Status Parameters

Status parameters give the operating status of the MultiRanger. You can access parameters with the hand programmer (see page 32) or with Dolphin Plus (see page 27). Remote SCADA system access is also possible.

Controlling the Display

RUN mode provides numerous parameters and variables that you can track on the display (see Display on page 22).

The LCD displays EEEE if a value is too long.

Adjusting the primary reading for four-digit LCD readout:

Example

To reference the displayed level to sea level, enter the distance in Units (P005), between Empty (P006) and sea level. (Enter a negative value if Empty is below sea level.)

P062 is the distance between sea level and Empty.

Auxiliary Reading

The Auxiliary Reading area of the LCD displays parameter values while leaving the primary reading on screen.

Note: The parameters shown in the auxiliary reading field are indexed as follows:

???global

???by transducer

???by level

Multiple Readings [MR 200 only]

During differential or average operation (P001 = 4 /5), the display scrolls sequentially through Point Numbers 1, 2, and 3. Point 3 is the difference between (or average of) Points 1 and 2.

Changing Number Scrolling Speed

See Parameter Indexing on page 37. All the instructions in the following procedures apply to the hand programmer and assume that the MultiRanger is activated.

PROGRAM Mode

The MultiRanger is programmed by setting its parameters to match your specific application. Most parameters are indexed, allowing you to set the parameter to specific conditions and to more than one input or output. When the MultiRanger is in PROGRAM mode, you can change these parameter values and set operating conditions.

Please refer to the Parameter Reference section on page 117 for a full listing and explanations of parameter values.

The MultiRanger???s primary programming is by the hand programmer. Other access is available through Dolphin Plus software (purchased separately).

SIMATIC Process Device Manager (PDM)

(compatible with product software versions 1.07 and later)1

SIMATIC PDM is a software package for parameterizing, commissioning, diagnosing and maintaining process devices. For the MultiRanger 100/200, SIMATIC PDM connects directly to the device using Modbus over Port 1 or Port 2.

The MultiRanger 100/200 comes with Port 1 set for communications to SIMATIC PDM.

SIMATIC PDM contains a simple process monitor of the process values, alarms and status signals of the device. Using SIMATIC PDM you can

???display,

???set,

???change,

???compare,

???check the plausibility of,

???manage, and

???simulate

process device data.

More information about SIMATIC PDM is available at www.siemens.com/processinstrumentation: go to Products & Solutions > Products & Systems > Communication and Software > Process Device Manager. Please consult the operating instructions or online help for details on using SIMATIC PDM. An Application Guide on using MultiRanger 100/200 with PDM and Modbus is available on our website: www.siemens.com/processautomation.

Activating the MultiRanger

All the instructions in the following procedures apply to the hand programmer and assume that the MultiRanger is activated.

1.Power the MultiRanger.

2.Point the programmer at the unit and press PROGRAM .

3.Press DISPLAY .

Note: Power up display

???Single Point Model

???preset to display distance from the face of the transducer to the material

???transducer selection is preset for the XPS-10

???empty distance is preset to 5 m

???Dual Point Model

???starts in an OFF state and does not take level measurements

???to set up measurement, the quick start parameters must be configured

???See Quick Start parameters on page 119

Changing Parameters

Note: If Parameter Value alteration is not permitted, access the Lock parameter (P000) and enter the security code, (see Security below).

1.Starting in RUN mode, press PROGRAM and then press DISPLAY to put the unit into PROGRAM mode.

2.Press DISPLAY to select the Parameter Number field.

3.Enter the Parameter Number (e.g. 110). After the third digit is entered, the parameter value is shown.

4.Enter the new value, and press ENTER . The MultiRanger interprets the value, either accepting or replacing it with a valid value.

Helpful Hints

???For parameters P001 to P009, press a single digit (1???9) and then press DISPLAY to show that parameter.

???The ? icon indicates that the MultiRanger has accepted the value but that it conflicts with other values entered. Double-check your programming.

???By default, the SCROLL arrows show only the Quick Start parameters and any that have been changed.

???P733 sets all parameters to be scroll-accessed.

Security

The Lock parameter P000 secures the MultiRanger against parameter changes via the handheld programmer. The unit can still be put into PROGRAM mode when locked, and parameter values can be viewed, but no parameter values can be changed.

When P000 is set to 1954, programming is enabled. To disable programming, enter another value.

P000 (1954) is a fixed value password. Therefore, you should use other means to secure the MultiRanger if security is a concern.

Simulation

P000 Lock also controls how simulations affect control relays. By default, control relays are unaffected by simulation levels. But if P000 is set to ???1, they react to the simulated level. See Parameters P925???P927 on page 220 for running a simulation.

Using Units or Percent (%)

Many parameters can be viewed either in measurement units (P005) or as a percentage. View the parameter and then press MODE to toggle between units and percentage. The LCD shows the selected measurement type, either units (m, ft) or percentage (%).

MR 200 only:

Percentage is also available when showing flow and volume with 100%, based on the parameter that defines the maximum.

Most examples in this manual use the icons from the hand programmer but nearly all functions are also available through Dolphin Plus.

Operation

Operation

Parameter Indexing

Parameters are indexed when they apply to more than one input or output. The index value defines the input/output for that parameter. Indexed parameters contain a value for each index, even if that index is not used.

MultiRanger Display

The index number and the index values are displayed above the parameter indicator on the LCD.

Primary and Secondary Indexes

Primary Index: relates to direct input or output and can refer to relays, communications ports, and other parameters. In parameters that allow secondary indexes, the primary index is often referred to as a point.

Secondary Index: relates to previously indexed parameters where the parameter requires a second index, permitting multiple values on an indexed input or output.

Average or Differential [MR 200 only]

For differential or average operation dual-point MultiRanger, set P001 to 4 (differential) or 5 (average) and connect two transducers of the same type.

All the relevant parameters are then indexed by the correct number:

Index Description

2indexed by Transducer One or Two

3indexed by level measurement 1 = Transducer One

2 = Transducer Two

3 = Calculated Level (average or difference)

Measurement Conditions

The following information will help you configure your MultiRanger for optimal performance and reliability.

Response Rate

The response rate of the device influences the measurement reliability. Use the slowest rate possible with the application requirements.

The response rate is also important to functions connected to the filling or emptying indicators.

Dimensions [MR 200 only]

The dimensions of the vessel, wet well, or reservoir (except empty and span) are only important if you require volume.

Volume is required to report the level value in terms of volume. The pumped volume function can also report pumped volume or pump efficiencies.

Failsafe

The failsafe parameters ensure that the devices controlled by the MultiRanger default to an appropriate state when a valid level reading is not available.

???P070 ??? Failsafe Timer activates if an error condition is detected. Upon expiration of the timer, relay status defaults to values based on P071.

???P071 ??? Failsafe Material Level determines the level reading if the Failsafe Timer expires and the unit is still in an error condition.

???P129 ??? Relay Failsafe controls the reaction of each relay. See Relay Failsafe on page 45 for more information.

If Failsafe Operation activates frequently, see the Troubleshooting Appendix on page 231.

Relays

Relays are the primary controls of external devices such as pumps or alarms. The MultiRanger comes with extensive control and alarm functions.

General Introduction

Depending on the model, up to six onboard multi-purpose relays are provided on the MultiRanger. Each relay may be independently assigned to one function and has a corresponding status icon on the LCD.

The relay functions fall under three modes of operation:

Relay Function

Note: The MultiRanger 100 or 200 can be programmed with relays. The number of relays installed depends on the model. To determine the number of available relays that can be utilized in your MultiRanger 100 or 200, open the lid and count the large white relays to the left of the display. It is important to count the number of on-board relays as the software will allow programming of up to six relays whether they are installed or not.

Alarm

Level

In high alarm, the function goes on when the level rises to the ON setpoint and goes off when the level lowers to the OFF setpoint. In low alarm, the function goes on when the level lowers to the ON setpoint and goes off when the level rises to the OFF setpoint.

In Bounds [MR 200]

The relay will be in alarm if the level is inside the zone between the setpoints.

Out of Bounds [MR 200]

The relay will be in alarm if the level is outside the zone between the setpoints.

Rate of Change [MR 200]

In filling alarm, the function goes on when the rate of filling increases to the ON setpoint and goes off when the rate of filling drops to the OFF setpoint. In emptying alarm, the function goes on when the rate of emptying increases to the ON setpoint and goes OFF when the rate of emptying drops to the OFF setpoint. For emptying alarm, the setpoints must be entered as negative values.

Relays

Relays

Temperature [MR 200]

In high alarm, the function goes on when the temperature rises to the ON setpoint and goes off when the temperature lowers to the OFF setpoint. In low alarm, the function goes on when the temperature lowers to the ON setpoint and goes off when the temperature rises to the OFF setpoint.

Loss of Echo

The function goes on when the fail-safe timer expires. The function goes OFF when a valid echo is received (fail-safe timer is reset).

Pump

Level

In pump down, the function goes on when the level rises to the ON setpoint and goes off when the level lowers to the OFF setpoint. In pump up, the function goes on when the level lowers to the ON setpoint and goes off when the level rises to the OFF setpoint.

Miscellaneous

Totalizer and Samplers [MR 200]

Refer to Totalizing Pumped Volume on page 65. Relays are normally de-energized, contact closure is approximately 200 mSec duration.

Setpoint - ON / OFF

If the ON setpoint is higher than the OFF setpoint, the relay operates as:

???high alarm

???pump down control

If the ON setpoint is lower than the OFF setpoint, the relay operates as:

???low alarm

???pump up control

The ON and OFF setpoints can not be the same on an individual relay but may be common to other relays. The dead band or hysteresis is the difference between the ON and OFF setpoints. For in and out of bounds level alarms, the hysteresis is set at ?? 2 % of span from either boundary.

Relays

P111???Control Functions

The control function energizes the relay coils. When the instrument is at rest (no controls operating) the relay coils are de- energized.

P112???Relay ON Setpoint

Sets the process point at which the relay is tripped.

P113???Relay OFF Setpoint

Sets the process point at which the relay is reset.

P118???Relay Output Logic

Affects relay reaction. Reverses the logic (normally-open to normally-closed or vice versa).

P129???Relay Failsafe

Changes how individual relays react to a failsafe condition on the instrument.

Relay Wiring Test

P119???Relay Logic Test

Checks the application wiring by forcing a relay control function, such as a level alarm or pump control setpoint. Ensure all the relay programming and wiring works properly.

Please verify that ON and OFF respond correctly. Use P119 as a final test once all of the relay programming is done.

Relay Activation

The flexibility of the relay functions ensures that the MultiRanger can support relay wiring for different systems and applications. Use the following as a guide to the most common parameters.

Relay Setpoints and Functionality

[MR 100]: When a setpoint is reached, the corresponding action is taken. The setpoint can be an ON or OFF setpoint related to a process variable.

[MR 200]: The setpoint can be an ON or OFF setpoint related to a process variable, or a timed setpoint based on interval and duration.

[MR 100]: Functions affected by setpoint are configured by parameters that determine the application requirements such as timing. P111 Pump and Control functions (see page 134) sets the functions requirements.

[MR 200]: Functions affected by setpoint are configured by parameters that determine the application requirements such as timing. P111 Pump and Control functions (see page 134 sets the function requirements. Other function parameters:

???P133???Pump Power Resumption Delay

???P645???Relay Duration

Relay Logic is Modified

Normal operating conditions means that alarms are off and pumps are on. This can be reversed using P118???Relay Output Logic.

Backup Level Override

Backup level override provides the option of overriding the ultrasonic input with another contacting point level device, for example, the Pointek CLS200. The ultrasonic reading is fixed at the programmed switch level until the discrete input is released and the ultrasonic device makes its decisions based on the override value.

Backup Level Override Parameters

P064: Reading Override Enable

Sets the discrete input as the source of a level reading override.

P065: Reading Override Value

Substitutes value for current reading when the discrete input (P064) is enabled. Value is added in current units and is valid only for the following:

???level

???space

???distance

???difference

???average modes of operation

???head level in OCM mode

Example:

A high level backup switch is connected to Digital Input Two in the same application as Transducer One at level value 4.3 m.

Settings

When the level rises to 4.3 m and the switch is activated, the reading is forced to 4.3 m where it stays until the switch is de-activated.

P066: Override Time Delay

Sets the time (in seconds) used to calm the override condition input.

Override Level Backup

Discrete Inputs

Discrete Inputs

Wiring the Discrete Inputs

Normal state is standard operation, with the MultiRanger sensing the material level and controlling the pumps.

The discrete input contacts are either normally-open or normally-closed when the system state is normal.

Example:

Normal state for a backup high level switch is open, and the contacts on the discrete input are wired as normally-open.

See Discrete Inputs on page 21 for complete details on wiring the discrete inputs. To override a level using a discrete input, see Backup Level Override on page 47.

Programming the Discrete Input Logic

The P270 series of parameters permits control over the discrete input.

The current value of the discrete input is reported in P275:

mA I/O

To integrate the MultiRanger with other equipment, use the mA input and outputs.

Note: When a mA input parameter is accessed, a mA symbol appears in the upper left corner of the LCD display.

The mA input can be used as a level measurement or can be passed on to a SCADA system.

mA Input [MR 200]

Level Reading Parameters

To pass the mA input on to a SCADA system, read the value from the appropriate communication registers. For more information, go to the MultiRanger Communications section on page 89.

mA Output

The MultiRanger has two mA outputs, used to send measurements to other devices.

Configuring the mA output to send a 4 to 20 mA signal scaled from 10% to 90% of span of the second transducer:

1.If the level reading drops below 10% of span, the mA output drops below 4 mA.

2.If the level reading rises above 90% of span, the mA output rises above 20 mA.

I/O mA

Volume [MR 200]

Volume is a feature of the MultiRanger 200 only. Volume is used in two situations:

1.Calculate and display volume instead of level. For programming all setpoint parameters in terms of volume units rather than level units.

2.Calculate pumped volume to accomplish the following:

???Totalize the volume of material that is pumped out of the wet well

???Set an alarm on pump efficiency

When using volume, readings are given in arbitrary units specified in P051.

The default is 100, which gives a reading in percent of total. Use whatever units you want here. If the value is too large for the four-digit LCD, use a larger unit.

Example

If a wet well has a maximum capacity of 250,000 liters, use the value 250.0 for P051 and set the reading in 1000s of liters.

Tank Shape and Dimensions

There are many common tank shapes to select from. (See P050. If possible, use one of these.) Each tank shape uses the Empty distance (P006) in its calculations of volume.

Some tank shapes also require extra dimensions to calculate the volumes. Do not estimate these values. They must be correct to ensure the accuracy of your volume calculations.

To configure volume for a tank with a half-sphere bottom, set the following:

Notes:

???The default reading changes to a range from 0 to 100 (the value in P051)

???Empty (P006) is still measured to the bottom of the tank, not the top of A.

Characterization Chart [MR 200]

If you cannot use a pre-defined tank, then use one of the universal tank shapes and program the characterization curve.

1.Plot a volume to height chart. Usually a tank supplier will provide this chart. However, if you have a custom-built wet well then you will need access to complete drawings of the well or accurate measurements.

2.Enter the curve values from this chart into P054 and P055.

3.Ensure extra points are added around sharp transitions in the wet well volume (e.g: as steps in the well wall).

Note: The end points in the curve are 0,0 (fixed) and the point defined by P007??? Span and P051???Maximum Volume.

In Bounds/ Out of Bounds Range [MR 200]

Use the bounded range alarms to detect when the level is inside or outside of the range. By using a bounded range alarm, you can effectively put two level alarms (high and low) on one relay.

Setting an Out of Bounds Alarm

Results:

???Trips alarm above 1.35 m and below 0.25m

???Resets alarm below 1.25 m and above 0.35m

Setting an In Bounds Alarm

Results:

???Trips alarm below 1.25 m and above 0.35 m

???Resets alarm above 1.35 m and below 0.25 m

Cable Fault

Activates an alarm if transducer cable circuit enters a shorted or opened state.

Temperature [MR 200]

Use the temperature alarm to activate an alarm when the temperature reaches the ON setpoint (P112). This alarm uses the same setpoint parameters as the level alarms (P112 and P113).

With P112 and P113, you can set a high alarm (P112 > P113) or a low alarm (P112 < P113).

This shows a high alarm:

The temperature source can be the temperature sensor built into the transducer or an external TS-3, as set by P660.

Starting Pumps by Rate of Level Change [MR 200]

Use this function when multiple pumps will be controlled by rate of level change rather than setpoints. Pumping costs can be reduced because only the highest ON setpoint needs to be programmed. This results in a lower difference in head to the next wet well which, in turn, results in less energy being used to pump out the well.

Control Pump

Pump Control

When the first ON setpoint is reached, the pumps will start, one by one, until the material level rate of change is set at the same value or greater than the value in:

???P703 ??? Emptying Indicator (pump down applications)

???P702 ??? Filling Indicator (pump up applications)

Set delay between pump starts using P132 ??? Pump Start Delay.

Single and Dual Point [MR 200]

???Single Point Mode: one pump by rate control available that affects all pumps.

???Dual Point Mode: a single pump by rate control can be set up for each of the three available level points. Set Operation for difference or average (P001 = 4 or 5).

Notes:

???Set all pump control relay ON and OFF setpoints to the same value

???If the level is within 5% of Span (P007) of the OFF setpoint, then the next pump is not started

Rotating Pumps by Service Ratio [MR 200]

Prerequisite: Set pump relays to a service ratio value (P111 = 54 or 55).

Notes:

???The MultiRanger will not sacrifice other pumping strategies to ensure that the ratio is held true

???If the pump relays are set to the same value, then the ratio equals 1:1 and all pumps are used equally (preset)

When more than one pump is assigned a Pump Service Ratio value (in any time units) and a pump start is required (P112 Relay Setpoint ON), the pump with the fewest running hours (with respect to the assigned ratio values) starts.

Conversely, when a pump stop is required (113 Relay Setpoint OFF), the pump with the most running hours (as compared to the assigned ratio values) stops.

Totalizing Pumped Volume [MR 200]

Prerequisite: the volume of the vessel must be known.

Set in RUN Mode

1.Press PROGRAM for RUN mode.

2.Press TOGGLE to display pumped volume on the totalizer.

3. Press AUXILIARY P to display current level in the auxiliary reading area.

Setting Independent Failsafe Controls

Independent failsafe controls allow you to vary an individual relay from the global failsafe controls programmed in P070 to P072.

Example:

The global failsafe controls are set to hold and Relay Five is set to trigger an alarm bell.

Control Pump

Pump Control

Setting a Pump to Run On [MR 200]

When you need to pump below the normal OFF setpoint, use P130 (Pump Run-On Interval) and P131 (Pump Run-On Duration) to control this event.

Example:

The pump connected to Relay Three is set to pump for an extra 60 seconds every 5 hours.

Note: P130 counts when the indexed relay is tripped, not the number of pump cycles. If the indexed relay only trips once every four pump cycles then the actual interval of the run-on will be 20 pump cycles, or five cycles of Relay Three.

Setting the Pump Start Delays [MR 200]

The pump start delay ensures that all of the pumps do not start at once to avoid power surges. There are two parameters used here: P132???Pump Start Delay and P133???Pump Power Resumption Delay. The default is 10 seconds but you can increase this if your pumps take longer to spin up.

Example:

The delay between pumps is set to 20 seconds and the delay of the first pump is set to 30 seconds.

Reducing Wall Cling [MR 200]

Use the Wall Cling parameter to randomly alter the ON and OFF setpoints over a range. This eliminates the ridge of material that builds up at the setpoint that can give false echoes.

This setting may increase the number of days between trips to clean the wet well.

Wall cling reduction is set by P136. The relay setpoints ON and OFF are randomly varied inside a range so the material level does not stop at the same point.

Example [MR 200]:

A range of 0.5 meters is used to vary the setpoint. The randomly-selected setpoints are always inside the ON and OFF setpoints.

Grouping Pumps [MR 200]

You can group pumps and use the same pumping algorithm separately on each group. If you specify different pumping algorithms then the pumps are already grouped by algorithm and you do not need to use this parameter.

Group pumps only when four pumps are using the same algorithm and you want to split them into two groups.

Example:

Pumps One and Two can operate as a group and Pumps Three and Four can operate as another group.

Setting a Flush Valve [MR 200]

A flush valve stirs up the sediment on the bottom of the well during pumping so that it doesn???t accumulate. These parameters will control any relays set with P111 = 64 (Flush Valve).

Most sets of parameters will work with only one or two changes; however, for these parameters to work, all of them must be set to a value.

Control Pump

Pump Control

Example:

The flush valve connects to Relay Four and the watched pump is on Relay One.

Relay Controlled by Communications

A relay can be controlled directly by a remote system through communications. No other control schemes can then be used with a relay configured this way. Communications can be used to force status of some control relays, such as pumps.

Setting Zero Head

Many PMDs start flowing higher than the traditional empty distance of the application. You can account for the flow in one of two ways:

1. Use P605 (Zero Head) to have OCM calculations ignore levels below that value. Possible head = P007 minus P605.

Note: P603 (Max. Head) is preset to P007 and is not updated when P605 is used. Make sure you set P603 to the correct value when using P605.

Universal Calculation Support

When the primary measuring device (PMD) doesn???t fit one of the standard types, it can be programmed using a universal characterization. When Universal is selected as the PMD type (P600), then both P610 and P611 must be entered to define the flow.

Two curve types are supported:

???P600 = 4???linear (piece wise linear)

???P600 = 5???curved (cubic spline)

Both are shown in the following chart.

Typical Flow Characterization

Characterization is achieved by entering the head (P610) and corresponding flow (P611), either from empirical measurement or from the manufacturer's specification. Increasing the number of defined breakpoints will increase the accuracy of the flow measurement.

Breakpoints should be concentrated in areas exhibiting the higher degrees of non linear flow. A maximum of 32 breakpoints can be defined. The curve???s end point is always specified by the parameters Maximum Head (P603) and Maximum Flow (P604) for a maximum total of 33 breakpoints.

Use as many breakpoints as required by the complexity of your PMD.

See Volume on page 51 for more information and parameters P610 and P611 for characterization.

Testing the Configuration

After programming the unit, you must test the device to ensure that it performs to your specifications. This test can be run in simulation mode or by varying the level in the application. The latter is preferred as it more accurately represents running conditions. However, if it is not possible to do a physical test, a simulation will ensure that control programming is correct.

Simulation

In simulation mode, the LCD display reacts to the simulated level changes. Alarm relays will also react to the simulation, but any pump or control relays will not react.

To allow pump or control relays to operate on the simulated level, set P000 to ???1.

Simulating a Single Measurement

Access the appropriate parameter: (press PROGRAM and then key in the parameter number). Press TRANSDUCER five times to overcome Echo Lock (P711) if applicable: the associated Reading is displayed in the Parameter Value field, and any alarm relays are set accordingly.

To verify Reading calculations (P920 to P926)

1.Go to the parameter to be simulated (P920, P921, P922, P923, P924, P925, or P926), and key in a material level in Units (Units defined in P005), or % of Span (% of Span defined in P007).

2.Press ENTER to display the calculated Reading. [Regardless of setting for P001, the parameter value being simulated will display as the primary reading. The auxiliary reading will always display the level value (P921). See ???Display??? on page 22 for positions of the primary and auxiliary readings on the LCD.]

3.Verify the calculated Reading. (At this point, the simulation is in Stop state. The effect of the ARROW key is based on this state. See chart on page 86.)

Note: When you set P001 = 3 (Distance), span (P007) is preset to empty (P006), therefore the primary and auxiliary readings may display the same value when Space (P922) is being simulated.

Simulating a Level Cycle

Starting a (P920, P921, P922, or P923) simulation when level = 0:

1.Go to the parameter to be simulated (P920, P921, P922, or P923).

2.Press ENTER to simulate level rise and fall. At the start of a simulation, the default rate is 1% of Span / second.

Configuration the Testing

Testing the Configuration

3.Press the ARROW or to adjust the simulated rate of rise or fall, based on the chart on page 86. The maximum rate is 4% of Span / second.

The effect of the ARROW key is determined by the state (rate of rise or fall) immediately before the key is pressed.

When the level rises to 100% or falls to 0%, it reverses direction at the same rate.

Checking Volume Characterization [MR 200]

To confirm universal volume calculations (P050 = 9, 10) are correct:

1.Go to P920.

2.Key in a level associated with a known volume.

3.Press ENTER .

4.Check the returned volume against the manufacturer???s chart.

5.Change parameters P054 and P055, as required.

6.Repeat steps 2 to 5 until the volume curve is verified.

Checking OCM Flow Characterization [MR 200]

To confirm universal flow calculations (P600 = 4, 5) are accurate:

1.Go to P925.

2.Enter a level with a known flow.

3.Press ENTER .

4.Check the returned flow against the manufacturer???s chart.

5.Change parameters P610 and P611, as required.

6.Repeat steps 2 to 5 until the flow curve is verified.

I/O Checkout

After the unit is installed, test to verify the wiring.

Relays

Use P119 to force a state change and verify that the results are as expected (pump starts, alarm sounds, etc.).

Discrete Inputs

Use P270 to force the input value and verify that the results are as expected.

1.Go to P270 [DI] where DI = the discrete input to be tested

2.Set P270 to 0 (forced OFF)

3.Go to P275 [DI] to verify that the value is forced

4.Check the state of outputs to ensure that they respond as expected

5.Go to P270 [DI]

6.Set P270 to 1 (forced ON)

7.Go to P275 [DI] to verify that the value is forced

8.Check the state of outputs to ensure that they respond as expected

For further information see Discrete Inputs section on page 48.

mA Input [MR 200]

Use P254 to test the mA input value against a true level. Use a trusted external mA source to generate the signal required for testing, and verify the incoming signal with P260. Check that the system responds as expected when the mA level is changed.

mA Output

Use an external device to test the mA output against the measured level. Check that the mA value changes to reflect the changes in the measured level.

Application Test

If you are testing the application by varying the material level (the preferred test method) make sure that none of the control devices is connected (or at least that no power is available to them).

If you are testing the application in simulation mode (and P000 is not ???1), then control relays are not energized and the control devices can remain connected.

While the level is being cycled, check the results of the discrete inputs either by closing the circuit externally (preferred) or by using P270 Discrete Input Function to force the input ON or OFF. Try all possible combinations to thoroughly test the setup. For each combination, run a complete cycle to verify that the relays operate as expected.

Configuration the Testing

Testing the Configuration

Monitor system performance carefully, under all anticipated operating conditions.

1.When the MultiRanger performs exactly as required, programming is complete.

2.If alternate Reading units, Failsafe action, or relay operation is desired, update the parameters for the new functionality.

3.If the system performance experiences problems, see General Appendix C: Troubleshooting, on page 231.

If you cannot observe all possible operating conditions during the System Performance Evaluation, use the level simulation (see page 85) to verify programming.

When a simulation is run, alarm relays will react to the simulated level changes, but control relays will not react. You can set P000 to value ???1 to trigger the control relays based on the simulated level.

Retest the system every time you adjust any control parameters.

P779 Modem Inactivity Timeout

Sets the time that the unit will keep the modem connected with no activity.

To use this parameter, ensure that P778 (Modem Available) =1. Ensure that the value is low enough to avoid unnecessary delays when an unexpected disconnect occurs but long enough to avoid timeout while you are still legitimately connected. This parameter value is ignored by the Modbus Master Drivers as they automatically disconnect when done communicating.

Hanging Up

If the line is idle and the P779 Modem Inactivity Timeout expires, then the modem is directed to hang up the line. Ensure that P779 is set longer than the standard polling time of the connected master device. Set P779 to 0 to disable the inactivity timer.

Product ID (R40,064)

This value identifies the Siemens device type:

Point Data (R41,010 ??? R41,031)

Measurement point data contain the current instrument readings. These are the values shown for the reading measurement for each measurement point. The reading is based on the setting for P001 (operation). P001 can be set to level, distance, OCM flow, or volume. See Parameter Reference section on page 117 for details.

The measurement registers are 41,010 to 41,012. The MultiRanger uses 41,010 when configured with a single transducer and 41,010 to 41,012 when configured with two transducers (P111=4 or 5 only). Two transducers can create three readings because they can generate an average or differential reading (R41,012) as well as the two level readings (R41,010 and R41,011).

Available registers:

The reading is expressed as a percentage of full scale, multiplied by 100:

Totalizer (R41,040 ??? R41,043)

The totalizers are stored as 32 bit integers using two registers. The totalizers can be read with R41,040 and R41,041 as totalizer for Point 1, and R41,042 and R41,043 as totalizer for Point 2. The totalizer values can be reset to any value by writing that value to the registers. The values can be cleared by writing zero (0) to the registers.

Input/Output (R41,070 ??? R41,143)

The MultiRanger has discrete inputs, mA inputs, mA outputs and relay outputs. See below for details for each I/O type.

Types Register Modbus

Modbus Register Types

Discrete Inputs (R41,070)

This table shows the current status of the discrete inputs. Only register 41,070 is used.

Relay Outputs (R41,080)

This table shows the current status of the relays. A reading of 0 means that the relay function is not asserted and a 1 means that it is asserted. For example, a 1 for a pump relay means that the pump is running.

Values are written to control a relay only if the Relay Control Function (P111) is set to communications (65). See Relay Function Codes (P111 Only) on page 110.

mA Input (R41,090) [MR 200]

The mA input is scaled from 0 to 2,000 (0 to 20 mA multiplied by 100). P254 displays the value of the input. This parameter is indexed by the input number.

mA Output (R41,110-41,111)

The mA output is scaled from 0 to 2,000 (0 to 20 mA multiplied by 100). This is displayed in P911.

Pump Control (R41,400 ??? R41,474)

Only relays set for pump control (P111 = 50 to 52) are available. These registers have no effect on relays programmed for other uses.

Pump ON Setpoint (R41,420 ??? R41,425)

The ON setpoint level (P112) for the referenced pump relay.

The setpoint is scaled from 0 to 10,000 (0 to 100% of span multiplied by 100). So 54.02% is shown in the register as 5402.

Modbus Register Types

Parameter Access (R43,998 ??? R46,999)

Parameter values are given as integers in the range of registers from R44,000 to R44,999. The last three numbers of the register correspond to the parameter number.

Usually, the parameters are all read / write.

Note:

???Parameters P000 and P999 are read only. If P000 is set to lock activated then all of the parameters are read only via the handheld programmer

???Parameter P999 (Master Reset) cannot be used via Modbus

???See Data Types on page 107 for a description of the different types of data associated with different parameters

Each parameter register has a corresponding format register that holds the format information required to interpret the value. See Format Words (R46,000 to R46,999) on page 105.

Parameter Indexing

Many parameters are indexed. There are two possible indexes: a primary index and a secondary index. A secondary index is a sub-address of the primary index. Some indexed parameters affect multiple I/O devices.

The following is an example of a primary index:

P111 is the Relay Control Function. This parameter determines how a relay is controlled by the MultiRanger (used as an alarm, for pump control, etc.). Because there are up to six relays on the MultiRanger, P111 is indexed by six to allow each relay to be programmed independently.

A few parameters also have a secondary index. While a secondary index is important for setting up the MultiRanger, it is almost never needed through remote communications.

Indexing the Parameter Access Area

Each parameter communicates its value to only one register. You must know the index(es) for the parameter in order to interpret the information in the register correctly.

For example, to make use of the value returned in register R44,111 you must know which relay it is referring to. See Relay Function Codes (P111 Only) on page 110 for details on P111 values.

To determine the index values, the primary and secondary index must be read or write. The two possible methods of handling these index values are described in the following paragraphs: Global Index Method and Parameter Specific Index Method.

Reading Parameters

To read parameter values, follow the steps listed in either the Global or the Parameter Specific Index Method that follow. You must be able to program your HMI or SCADA system before completing these methods.

Global Index Method (P782 = 0)

Global format method sets index values for all parameters simultaneously. Use this method to read multiple values set to the same index values.

1.Write the primary index value into R43,999.

This is a value between 0 and 40 which specifies the input or output indexed by the parameter.

Examples are:

???Transducer 1 is index 1

???Discrete input 2 is index 2

???Relay 5 is index 5

2.Write the secondary index value into R43,998.

This is a value between 0 and 40 that specifies the secondary index on the parameter. This value is usually 0.

3.Write the desired format value into the appropriate format register. Because the primary and secondary indexes are already specified, these portions of the format word are ignored and only the last digit is significant.

See Format Registers on page 115 for details.

4.Read the value from the appropriate parameter register.

Types of values are:

???Numeric Values, on page 107

???Bit Values, on page 107

???Split Values, on page 108

???Text Messages, on page 109

???Relay Function Codes (P111 Only), on page 110

A value of 22,222 indicates that an error has occurred. Specify a different format type and try again.

Parameter Specific Index Method (P782 = 1)

The Parameter Specific index method sets the index values for each parameter independently. Use this method to read multiple parameters with different index values.

1.Write the primary index, secondary index, and data format values into the appropriate format register.

For example, to read the following information:

???measured level (P921)

???in units with three decimal places

Types Register Modbus

Data Types

The MultiRanger parameters do not always use integers to hold values. For the convenience of the programmer, those values are converted to and from a 16-bit integer number. This section describes the conversion process. The sections that follow describe where those values are in the discrete I/O and block transfer addresses, and how to get the parameters you need.

Numeric Values

Numeric parameter values are the most common. For example, parameter P920 (Reading) returns a number that represents the current reading (either level or volume, depending on the MultiRanger configuration).

Numeric values are requested or set in units or percent of span, and may be specified with a number of decimal places.

Numeric values must be in the range ???20,000 to +20,000 to be valid. If a parameter is requested and its value is more than +20,000, the number 32,767 is returned; if it is less than ???20,000, the number ???32,768 is returned. If this overflow happens, decrease the number of decimal places.

If a parameter cannot be expressed in terms of percent of span, or has no meaningful value, the number 22,222 is returned. Try requesting the parameter in units, or refer to P005 in the Parameter Reference section on page 122.

Bit Values

Bits are packed into registers in groups of 16 bits (1 word). In this manual, the bits are numbered from 1 to 16, with bit 1 as the least significant bit (LSB) and bit 16 as the most significant bit (MSB).

Unsigned Double Precision Integer (UINT32)

Large numbers are put into unsigned 32 bit integers. By default, they are set up so that the first word (register) is the most significant word (MSW) and the second word (register) is the least significant word (LSW).

Types Data

Data Types

For example, if R41,442 is read as a UINT32, the 32 bits would look like this:

The two registers are read as a 32-bit integer.

The most significant word (MSW) and least significant word (LSW) can be reversed to accommodate some Modbus drivers. See Word Order (R40,062) on page 98 for details.

The position of the decimal place is dependent on the register. For more details see the description of the register.

Split Values

Certain parameters are actually a pair of numbers separated by a colon, using this format: xx:yy.

One example is P807, Transducer Noise, where:

xx= the average noise value in dB

yy= the peak noise in dB

The number which corresponds to xx:yy, either for reading or setting a parameter, is determined by the following formula:

For storing to the device:

value = (xx + 128) x 256 + (yy + 128) For reading from the device:

xx= (value / 256) ??? 128 yy = (value % 256) ??? 128

where % is the modulus operator.

The modulus can be computed by following these steps: value1 = value / 256

value2 = remainder of value1 value3 = value2 x 256

yy = value3 ??? 128

It may simplify Parameter to notice:

xx= (most significant byte of value) ??? 128

yy= (least significant byte of value) ??? 128

Text Messages

If a device parameter returns a text message, that message is converted to an integer and provided in the register. The numbers are shown in the following table:

Types Data

Data Types

Relay Function Codes (P111 Only)

Please note that the MultiRanger 200 offers more function codes.

If a device parameter returns a relay function code, that message is converted to a number and is then provided in the register. The numbers are shown in the following table:

MultiRanger 100

See P111 on page 134 of theParameter Reference section.

Communication Appendix A

Communication Appendix A: Single

Parameter Access (SPA)

This Appendix is intended to provide someone with advanced communications knowledge the ability to access any parameter value in any available format.

Built into MultiRanger is an advanced handshaking area that can be used to read and write single registers to the MultiRanger. This section performs a similar function to the Parameter access section. The differences are:

1.Advanced section is more powerful and harder to program.

2.Advanced section only gives you access to one parameter at a time.

Mapping

Parameter Read and Write (40,090 ??? 40,097) is a series of eight registers used for reading and writing parameter values to and from the MultiRanger. The first three registers are always unsigned integers representing parameters and index values. The second five registers are the format and value(s) of the parameter.

All parameters normally accessed through the hand-held programmer are available through these registers.

Reading Parameters

To read parameters through Modbus do the following steps:

1.Send the parameter, its primary index, and its secondary index (usually 0), and format to registers 40,090 to 40,093.

2.Wait until you can read the written values from the registers (40,090 to 40,093) to confirm that the operation is complete.

3.Read the value from registers 40,094 and 40,095.

Writing Parameters

To set parameters through Modbus do the following steps:

1.Send the parameter, its primary index, and its secondary index (usually 0) to registers 40,090, 40,091, and 40,092.

2.Write the value to registers 40,096 and 40,097.

3.Write the desired format word to register 40,093 to enable the MultiRanger to interpret the value correctly.

Format Register

For example, to format the level reading so that it is shown in percent with two decimal places shifted left, the format bits would look like this:

The value sent to the MultiRanger is 0001001000000000 binary or 512 decimal. The value 512 is sent as an integer to register 40,093 to format the output words 40,094 and 40,095 accordingly.

If the numeric data type is set for integer and the value contains decimal places, they are ignored. In this situation, use the decimal offset to ensure that you have an integer value and then write your code to recognize and handle the decimal offset.

Parameters

P005 Units

Specifies measurement units used for dimensional values.

Changing this value automatically changes the units displayed for many parameters. Existing values are converted and do not have to be re-entered.

P006 Empty

Enter distance in units (P005) from the face of the transducer to the process empty point.

Setting this value also sets Span (P007) unless Span was already set to another value. For distance operation (P001=3), Span is preset to Empty.

P007 Span

Sets the range levels to be measured.

Span is preset for a value close to the maximum available. Enter a value reflecting maximum application range.

Always prevent the monitored surface from approaching within 0.3 m (1 ft) of the transducer face as this is the minimum blanking for most Siemens Milltronics transducers (some require more blanking ??? see your transducer manual).

Many other parameters are set as a percentage of span (even if they are entered in units). The values of these other parameters may change if the span is altered after installation and the other parameters are measured using a level determined upward from the Empty level toward the transducer face.

MultiRanger 200

All volumes are based on span so it should be set for the maximum volume point if volume calculations are needed.

Volume (P050 to P055) [MR 200]

Please note that the volume parameters apply only to the MultiRanger 200.

Use these parameters to enable the MultiRanger to show readings based on vessel or wet well volume (rather than level)..

Parameters

Parameters

P052 Tank Dimension A [MR 200]

Dimension A as used in P050 Tank Shape.

Enter one of the following:

???height of the tank bottom if P050 = 2,3,4, or 5

OR

???length of one end section of the tank if P050 = 7, in Units (P005)

P053 Tank Dimension L [MR 200]

Dimension L as used in P050 Tank Shape.

Enter the following:

???tank length (excluding both end sections) if P050 = 7

P054 Level Breakpoints (Universal Volume Calculation)

[MR 200]

When the tank shape is too complex for any of the preconfigured shapes, you can specify the volume based on segments.See ???Accessing a Secondary Index??? on page 117 for more information.

Enter the following:

???up to 32 level breakpoints (where volume is known) if P050 = 9 or 10

Entering a Level Breakpoint

1.Go to Parameter P054.

2.For each index enter a breakpoint in measurement units.

3.Ensure that each breakpoint corresponds to the same index for P055.

Parameters

In RUN mode, the decimal position adjusts to prevent the number of digits from exceeding the display capabilities. To keep the decimal place from shifting, reduce the number of decimal places to that shown at 100%.

Example:

If 100% is 15m, use two decimal places for sample readings of 15.00 or 12.15.

P061 Convert Reading [MR 200]

Multiplies the current value by the specified amount to allow for scaling.

Examples:

???If the measured value is in feet, enter 0.3333 to display the number of yards

???For simple linear, volume conversions set POO5 to 1 (meters) and then enter the volume measurement per unit to get the correct conversion. For example, if the reservoir contains 100 litres per vertical meter, use 100 to get the reading in litres.

Notes:

???This method does not calculate volume. It must not be used in place of the volume parameters if any volume dependent features (such as pump efficiency) are used. To calculate true volumes see Volume (P050 to P055).

???Avoid entering a value that, when multiplied by the maximum current Reading, exceeds the display capabilities. If value exceeds four digits, EEEE is shown.

P062 Offset Reading

Adds the specified value to the level reading, usually to reference the reading to sea level or another datum level.

The operation of the device is not affected by the Offset Reading. This value is used for display purposes only. All control measurements are still referenced to Empty.

Parameters

Please note the following:

???enter value in current units (as selected in P005)

???valid for level, space, and distance

???volume is calculated based on the Backup level

Example:

Transducer One is configured for a level measurement. Digital Input 2 is connected to a Hi Level Backup switch located a level of 4.3m.

When the level rises to 4.3m, and the switch is activated, the reading is forced to 4.3m. The reading stays at 4.3m until the switch is de-activated.

P066 Override Time Delay

Defines the time used to calm (debounce) the override condition input. Set in seconds.

Note: Activation of the Level Override is subject to the measurement cycle. This can add up to four seconds to the overall response time depending on operating conditions and programming.

P069 Password

Holds the current password for P000.Select by typing in 069.You cannot scroll to this parameter.

This parameter is write-only, and can only be selected by entering 069. To change the password, unlock the device by entering the current password into P000. Then enter the new password into P069. To lock the device, enter a password other than the correct one in P000. While the device is unlocked, the password is visible in P000.

Failsafe (P070 to P072)

P070 Failsafe Timer

The time for invalid measurements to elapse before Failsafe State activates.

Once activated, the Failsafe State initiates the following:

1.The material level is reported based on P071 Failsafe Material Level.

???The unit responds to the new level as programmed (control and alarm relays activate as defined by the programming).

???Individual relays can have independent failsafe responses. See P129 Relay Failsafe.

2.The appropriate error is displayed:

???LOE for loss of echo from the transducer

???Short for a shorted transducer cable

???Open for a cut transducer cable

???Error for all other problems

When modifying the preset value, set it short enough to protect the process but long enough to avoid false alarms. Only use No Delay (0.0 Minutes) for testing.

P071 Failsafe Material Level

The material level reported when a Failsafe State is initiated.

Select the Failsafe Material Level based upon the relay operation required during failsafe operation.

Parameters

Parameters

Selecting HI, LO, or HOLd

1.Press FUNCTION to display the Auxiliary Function symbol.

2.Press ARROWS to scroll to the desired option.

3.Press ENTER to set the value.

Entering a Measurement

To enter a specific Failsafe Material Level within -50 to 150% of Span (P007), in Units (P005).

Relay reaction

The way in which relay programming reacts to the failsafe level depends on P129 Relay Failsafe (page 140). By default:

???Alarm relays have P129 = OFF and so react to the Failsafe Material Level.

???Control relays have P129 = dE and so de-energize the relay when the unit enters Failsafe mode regardless of the Failsafe Material Level.

P072 Failsafe Level Advance

Sets the speed the MultiRanger advances to and returns from the Failsafe Material Level.

Relays (P100 to P119)

The MultiRanger has three or six relays (or digital outputs) used to control devices and alarms. While the number of devices is limited by the relays, all control functions are accessible through software and each parameter is indexed to the three or six relays. See the Relay section on page 41.

Preset Applications (P100)

The MultiRanger makes standard applications easier to program by providing an extensive list of presets.

Enter the dead band in either percent of span or units of measure (P005). The dead band value is applied both above and below the upper and lower bound setpoints as shown in the fig- ure.

Actual ON or OFF setpoint

P116

Setpoint set in P112 or P113 P116

Actual OFF or ON setpoint

Parameters

P118 Relay Output Logic

The logic applied to relays to determine the contact open or closed state.

The relay contact operation is NORMALLY CLOSED for alarms and NORMALLY OPEN for controls. See P111 Relay Control Function for more information.

Note: P118 is not reset by a master reset (P999).

Power Failure

When power is cut to the MultiRanger, its relays fail to the following states:

1.Relays 3 and 6 are Form C types, so you can wire it either NORMALLY OPEN or NORMALLY CLOSED. Check the wiring before programming.

To use relays 3 or 6 as general alarm indicators, set P118 to 3 ??? negative logic and wire the alarm for normally open operation. When an alarm event occurs (see below) or when power is cut, the circuit closes and the alarm activates.

Positive Logic

In software, all relays are programmed the same way, with ON setpoints indicating when to change the relay contact state (open or closed). This parameter allows the reversal of the operation so that relay contacts can be NORMALLY CLOSED or NORMALLY OPEN.

P118 is preset to 2 which is positive logic.

Negative Logic

When P118 = 3 (negative logic), the operation for the indexed relay is reversed from normal.

P119 Relay Logic Test

Forces the relay control logic into an ACTIVATED or DE-ACTIVATED state.

This parameter tests site wiring and control logic programming. Forcing the relay to an activated or de-activated state is similar to the MultiRanger detecting an event and responding to it. Helpful in testing new installations and diagnosing control problems.

Pump Setpoint Modifiers (P121 and P122) [MR 200]

Please note that these parameters apply to the MultiRanger 200 only.

These parameters provide alternate ways of starting the pumps in the pump group. See the Pump Control section on page 58 for descriptions of the pump control algorithms.

P121 Pump by Rate [MR 200]

Sets the pump relays to accept control by rate of level change once the first ON setpoint is reached.

Use this function when multiple pumps are to be controlled by rate of level change rather than by setpoints.

Parameters

Parameters

The delay between pump starts is set by P132 Pump Start Delay.

This only applies to any relays set to pump control (P111 = 50 to 56).

Notes:

???All pump control relay ON and OFF setpoints must be the same value

???If the level is within 5% of Span (P007) of the OFF setpoint, the next pump is not started

P122 Pump Service Ratio [MR 200]

Selects pump usage based on the RUN time ratio rather than last used.

This parameter only relates to relays with P111 = 54 or 55.

To make this parameter useful, assign it to all of the pump relays. The number assigned to each pump relay represents the ratio applied to decide the next pump to start or stop.

Notes:

???The MultiRanger will not sacrifice other pumping strategies to ensure that the ratio is held true

???If the pump relays are set to the same value then the ratio equals 1:1 and all pumps are used equally (preset)

Independent Relay Failsafe (P129)

P129 Relay Failsafe

Sets how individual relays react to a failsafe condition, to allow for more flexible programming.

Use this for operations independent of the Failsafe Material Level (P071).

Parameters

P131 Pump Run-On Duration [MR 200]

Sets the number of seconds that the pump runs on.

Your pump capacity determines the amount of material that can be removed. Choose a value long enough to clean out the vessel bottom, yet short enough not to run the pump dry. Also be sure that this value does not overlap with P130 (Interval). The timing should look something like this:

P132 Pump Start Delay [MR 200]

Sets the minimum delay (in seconds) between pump starts.

Use this feature to reduce a power surge from all pumps starting at the same time. This delay determines when the next pump is permitted to start.

P133 Pump Power Resumption Delay [MR 200]

Sets the minimum delay before the first pump restarts after power failure.

This reduces the surge from the first pump starting immediately on power resumption. When this delay expires, other pumps will start as per P132.

Parameters

Flush Systems (P170 to P173) [MR 200]

Please note that these parameters apply to the MultiRanger 200 only.

Use this feature to control an electrically operated flush valve on a pump to divert some pump output back into the wet well to stir up sediment.

Notes:

???If any of the following parameters are set to 0, this feature will not work.

???In Dual Point mode, a flush valve can be set up for each of the three available level inputs (P001 = 4 or 5).

Single Point Mode

Enter the MultiRanger relay number of the pump with the flush valve. The activation of this pump relay drives the usage of the flush system. Both P172 Flush Interval and P171 Flush Cycles are based on the operation of this relay and control any relay set to P111 = 64, Flush Valve.

Dual Point Mode

The indexed relay is the one that controls the flush device. The value is the pump relay that is watched by the flush system. Enter the pump relay value into the parameter at the flush relay index.

Example

If you need to watch pump Relay One to control a flush valve on Relay Two you would set P170[2]=1.

P170 Flush Pump [MR 200]

Picks the number of the pump relay which triggers the flushing device.

Enter the MultiRanger relay number of the pump with the flush valve. The activation of this pump relay drives the usage of the flush system. Both P172 Flush Interval [MR 200] and P171 Flush Cycles [MR 200] are based on the operation of this relay and controls any relay set to P111 = 64, Flush Valve.

Independent mA Setpoints (P210 and P211)

Use these features to reference the minimum and/or maximum mA output to any point in the measurement range.

P210 0/4 mA Output Setpoint

Sets the process level corresponding to the 0 or 4mA value.

Enter the value (in applicable units or %) to correspond to 0 or 4 mA.

P211 20 mA Output Setpoint

Sets the process level that corresponds to the 20 mA value.

Enter the value (in applicable units or %) to correspond to 20 mA.

mA Output Limits (P212 and P213)

Use these features to adjust the minimum and/or maximum mA output values, which should suit the input limit requirements of the external device.

Parameters

Parameters

P212 mA Output Min Limit

Sets the minimum mA output value (in mA) to be produced.

P213 mA Output Max Limit

Sets the maximum mA output value (in mA) to be produced.

mA Output Trim (P214 to P215)

This does not affect the P203 value shown, and is used when recalibration of an external device is impractical.

To adjust the value so that the device correctly indicates 4.00 (when P214 is accessed) or 20.00 mA (when P215 is accessed):

1.Attach ammeter to MultiRanger 4 to 20 mA output.

2.Access P214, Index 1 (for mA output 1) or 2 (for mA output 2). Press CLEAR and

ENTER . The ammeter should show a value near 4 mA.

3.Enter the exact value displayed on the ammeter into P214 (Index 1 or 2).

4.The ammeter should then read exactly 4.00 mA.

5.Repeat steps 1 to 4 to set P215, using 20 mA as the desired value.

P214 4 mA Output Trim

Calibrates the 4 mA output.

Adjust this value so the device indicates 4.000 mA when P214 is accessed.

P215 20 mA Output Trim

Calibrates the 20 mA output.

Adjust this value so the device indicates 20.00 mA when P215 is accessed.

mA Output Failsafe (P219) [MR 200]

Please note that this parameter applies to the MultiRanger 200 only.

P219 mA Output Failsafe [MR 200]

Use for failsafe operation, independent of the Failsafe Material Level (P071).

Selecting an independent mA Failsafe option:

1.Press MODE to display the Auxiliary Function symbol.

2.Press ARROWS to scroll access the failsafe options.

3.Press ENTER when the desired option displayed.

Or, to produce an mA output at a specific value, enter the value required. This is used only if mA output is allocated to a transducer (P201 = 1 to 7).

mA Input (P250 to P260) [MR 200]

Please note that these parameters apply to the MultiRanger 200 only.

Parameters

Parameters

P270 Discrete Input Function

Sets how discrete signals are interpreted by the MultiRanger.

P275 Scaled Discrete Input Value

Shows the current value of the discrete input after any scaling is applied.

Readings are updated continuously even in PROGRAM mode. The value signals a level override event.

Standard Data Logging (P300 to P321)

All records can be reset by pressing the CLEAR keys.

Record Temperatures (P300 to P303)

These features display the high and/or low temperatures in ??C. When a parameter relating to a TS-3 Temperature Sensor is accessed, the Point Type display changes to the

TS-3 symbol .

If the unit is powered up without a temperature sensor connected, the value ???50??C is displayed. This information can help trace problems with both built in and external temperature sensors.

Parameters

P303 Temperature, Sensor Minimum

Shows the lowest temperature encountered, as measured by the TS-3 Temperature Sensor (if applicable).

Record Readings (P304 and P305)

This identifies the occurrence of the record high and low level readings. Press CLEAR keys to reset these values once the installation is working correctly.

P304 Reading Max

Shows the highest Reading calculated (in normal Reading units or %).

P305 Reading Min

Shows the lowest Reading calculated (in normal Reading units or %).

Pump Records (P309 to P312)

These features to identify pump usage and if the associated Relay Function (P111) is set for any pump control feature. The value is that of the pump connected to the associated terminals.

Enter a value to set the current record to that value. Use this if a pump is added with a known number of hours logged, or the value can be reset to zero 0 after maintenance.

Parameters

Flow Records (P320 and P321) [MR 200]

Please note that these parameters apply to the MultiRanger 200 only.

These features are enabled if Operation is set for OCM (P001 = 6), or an OCM device is defined (P600 ??? 0). Use them to identify the occurrence of the record high and low flow rates as displayed in OCM Max Flow (P604) units, or as a percent of OCM Max Flow.

Press CLEAR keys to reset values once the installation is working correctly.

P320 Flow Max [MR 200]

LCD Totalizer (P322 and P323) [MR 200]

Please note that these parameters apply to the MultiRanger 200 only.

Use these features to view, reset, or preset the eight-digit display totalizer when Operation is set for OCM or Pumped Volume (P001 = 6 or 7). The eight-digit totalizer is divided into two groups of four digits. The four least significant totalizer digits are stored in P322, and the four most significant digits are stored in P323. Adjust these values separately to set a new total.

Example

P323 = 0017

P322 = 6.294

Totalizer Display = 00176.294

Totalizer units are dependent upon programming. Enter zero 0 (if required) to reset the totalizer to zero. Alternatively, enter any other (applicable) value, to preset the totalizer to the necessary value.

Note: A second point is available only if the Dual Point Feature is enabled.

P322 LCD Total Low [MR 200]

P323 LCD Total High [MR 200]

View and/or alter the four most significant digits of the totalizer value.

Profile Records (P330 to P337)

WARNING:

These parameters are for authorized service personnel or technicians familiar with Siemens Milltronics echo processing techniques.

These features can record up to ten Echo profiles, initiated manually (P330), or automatically (P331 et al). If ten Profiles are already saved, addresses 1 through 10 are filled, the oldest automatically initiated record is overwritten. Manually initiated records are not automatically overwritten. All records are automatically deleted in the event of a power interruption.

When a record is displayed, results are based on current programming (which may have been altered since the record was saved). This permits the effect on the echo profile to be observed when changing an echo parameter.

For more information on PMD, see page 73.

Parameters

Parameters

P603 Maximum Head [MR 200]

The level value associated with Maximum Flow, in Units (P005).

This represents the highest head level supported by the PMD and works in conjunction with Maximum Flow (P604) to define the highest point in the exponential curve. Use it when the Primary Measuring Device (PMD) requires a maximum head and flow reference point. This would include Exponential, Palmer Bowlus Flume, H-Flume, and Universal breakpoints.

P604 Maximum Flow [MR 200]

The maximum flowrate associated with Maximum Head (P603).

This represents the flow at the highest head level supported by the PMD. and works in conjunction with Maximum Head (P603) to define the highest point in the exponential curve. Use it when the Primary Measuring Device (PMD) requires a maximum head and flow reference point. This would include Exponential, Palmer Bowlus Flume, H-Flume, and Universal breakpoints.

Also use this parameter with Time Units (P606) to define the flowrate units. The limitation of four digits is for the LCD only, and the flowrate value is available with greater precision through communications.

Parameters

Parameters

P633 LCD Totalized Decimal Position [MR 200]

Enter the maximum number of decimal places to be displayed.

Note: Set the decimal position during initial commissioning of the MultiRanger 200. If the position is changed later, the totalizer data in P322 and P323 will be incorrect and must be reset according to the new decimal value.

In RUN mode, the number of decimal places displayed is not automatically adjusted. When the LCD Total value is so large as to exceed display capabilities, the total rolls over to 0 and continues incrementing.

P640 Remote Totalized Multiplier [MR 200]

Use this feature if the remote totalizer (device connected to the relay set for totalizer operation [relay Function, P111 = 40]), updates too slowly or rapidly.

Parameter is relevant only if Operation is set to OCM or Pumped Volume (P001 = 6 or 7). The relays on the MultiRanger have a maximum frequency of 2.5 Hz.

P651 Sound Velocity Calibration

Changes the speed of sound constant.

Condition for use of this feature

???The acoustic beam atmosphere is other than air

???The acoustic beam atmosphere temperature is unknown

???The Reading accuracy is acceptable at higher material levels only

For best results, calibrate with the level at a known value near empty.

Parameters

P654 Velocity at 20??C

This value is used to automatically calculate Sound Velocity (P653).

After performing a Sound Velocity Calibration, check this value to verify the acoustic beam atmosphere is air (344.1 m/s or 1129 ft/s).

Alternatively, if the acoustic beam atmosphere sound velocity at 20??C (68 ??F) is known, and the sound velocity vs. temperature characteristics are similar to that of air, enter the sound velocity.

The units used are m/s if P005 = 1, 2, or 3 (or ft/s if P005 = 4 or 5).

Temperature Compensation (P660 to P664)

P660 Temp Source

Source of the temperature reading used to adjust the speed of sound.

The MultiRanger uses the TS-3 temperature sensor assigned to the transducer. If one is not connected, the ultrasonic/temperature transducer is used. If the transducer does not have an internal temperature sensor, the Temp Fixed (P661) value is used.

If the acoustic beam atmosphere temperature varies with distance from the transducer, connect a TS-3 Temperature Sensor and ultrasonic / temperature transducers, and select average.

Parameters

P664 Temperature

View the transducer temperature in ??C.

If Temp Source (P660) is set to any value other than Fixed Temp, the value displayed is the temperature measured. If Temp Source is set to Fixed Temp, the P661 value is displayed.

Rate (P700 to P708)

These parameters determine how material level changes are reported.

P700 Max Fill Rate

Adjusts the MultiRanger response to increases in the actual material level (or advance to a higher Failsafe Material Level, P071).

Enter a value slightly greater than the maximum vessel filling rate. This value, in Units (P005) or % of Span (P007) per minute, is automatically altered when Maximum Process Speed (P003) is altered.

Parameters

P703 Emptying Indicator

The empty rate required to activate the LCD Emptying indicator ().

This value (in Units (P005) or % of Span (P007) per minute) is automatically set to 1/10 of the Max Empty Rate (P701).

P704 Rate Filter

Damps Rate Value (P707) fluctuations.

Enter the time or distance interval over which the Rate Value is to be calculated before the display updates.

This is automatically altered along with Maximum Process Speed (P003).

This value automatically alters the Rate Update Time (P705) and / or Rate Update Distance (P706). Alternatively, these parameter values may be altered independently.

Parameters

P728 Shot Delay

The delay, in seconds, between transducer shots.

Range: 0.1 to 4.0

Values

Preset: 0.5

Use this if transient acoustic noise within the vessel is causing measurement difficulties due to echoes from one shot being received on the next. If more than one ultrasonic unit is installed for redundancy, this value should be 0.

Parameters

SmartLinx Reserved (P750 to P769)

These parameters are reserved for optional SmartLinx communications cards and vary by card. Refer to the SmartLinx documentation to determine if any of them are used.

Communications (P770 to P782)

The MultiRanger communication ports are configured by a series of parameters that are indexed by port. See the Communications section on page 89 for a complete description of communications set-up.

Communication parameters are indexed to these communication ports, unless otherwise noted:

1RS-232 port (RJ-11 modular telephone)

2RS 485 port on terminal block

P770 Port Protocol

The communications protocol used between the MultiRanger and other devices.

The MultiRanger supports the internationally recognized Modbus standard in both ASCII and RTU formats. Other protocols are available with optional SmartLinx cards.

P771 Network Address

The unique identifier of the MultiRanger on the network.

Range: 0 to 9999

Values

1 * Preset:

For devices connected with the Siemens Milltronics protocol this parameter is ignored. For devices connected with a serial Modbus slave protocol, this parameter is a number from 1-247. The network administrator must ensure that all devices on the network have unique addresses. Do not use the value 0 for Modbus communications as this is the broadcast address and is inappropriate for a slave device.

P782 Parameter Index Location

Determines where index information is stored for the parameter access area.

0 * Global

Values

1Parameter-Specific

Global (0)

The primary and secondary index values are global (they affect all of the parameter access area at once) and stored in:

???primary index ??? R43,999

???secondary index ??? R43,998

Parameter-Specific (1)

The primary and secondary index values are encoded into the format words found between R46,000 and R46,999. Each format work corresponds with the R44,000 series number in the parameter access map. For example, the format register R46,111 corresponds to the parameter P111 and the value is stored in R44,111. If the Modbus protocol (P770 = 2 or 3) is not used this parameter is ignored.

SmartLinx Hardware Testing (P790 to P795)

Note: These parameters are used to test and debug a SmartLinx card (if installed). Disregard these parameters if you do not have a SmartLinx card installed.

P790 Hardware Error

The results of ongoing hardware tests in the communications circuitry.

If FAIL or ERR1 is displayed in P790 (Hardware Error), go to P791 (Hardware Error Code) and P792 (Hardware Error Count) for information about the error.

Parameters

P799 Communications Control

Enables the read/write access to parameters via remote communications.

Notes:

???P799 controls the lock access via communications.

???P000 controls the lock access via the Siemens handheld programmer.

Echo Processing (P800 to P807)

P800 Near Blanking

The space near the transducer face which cannot be measured.

Use this feature if the surface is reported to be near the transducer face but is in fact much further away. Extend this value when changing transducer location, mounting, or aiming.

Please note that changing the Near Blanking cannot correct measurement problems. Ensure that Span (P007) < Empty (P006) minus Near Blanking (P800)

Parameters

Parameters

P805 Echo Confidence

Displays the echo confidence of the measurement echo from the last shot.

Use this feature to monitor the effect of transducer aiming, location, and mechanical transducer / mounting isolation.

Both short and long shot Echo Confidence is displayed. (To display this value in the auxiliary display while the unit is running, press for 4 seconds.)

Etransducer cable is open or short circuited.

P806 Echo Strength

Displays the strength (in dB above 1 uV RMS) of the echo which was selected as the measurement echo.

P807 Noise

Displays the average and peak ambient noise (in dB above 1 uV RMS) being processed.

The noise level is a combination of transient acoustic noise and electrical noise (induced into the transducer cable or receiving circuitry). See Noise Problems in the Troubleshooting Section on page 232.

Advanced TVT Adjustment (P830 to P835)

The following parameters are for authorized Siemens Milltronics Service personnel or technicians familiar with Siemens Milltronics echo processing techniques.

Advanced TVT control applies to long shots only.

P830 TVT Type

Selects the TVT Curve used.

Select the TVT type which gives the highest confidence (P805) under all level conditions. Use this parameter with caution, and do not use TVT Slopes with the bF or bLF Algorithm (P820).

P831 TVT Shaper

Turns the TVT Shaper ON or OFF.

Turn the TVT Shaper ON before using P832 and afterwards. Turn the TVT Shaper ON and OFF while monitoring the effect to pick up the true echo.

Parameters

Parameters

P832 TVT Shaper Adjust

Allows manual adjustment of the TVT curve. Use this parameter in conjunction with Dolphin Plus PC Software.

Use this feature to bias the shape of the TVT curve to avoid selecting false echoes from fixed objects.

Adjustment to this parameter is best done while viewing the echo profile with Dolphin Plus. Refer to the Dolphin Plus online help for details.

The TVT curve is divided into 40 breakpoints, accessible by enabling the point number as the breakpoint index field. Each breakpoint is normalized to a value of 0, as displayed in the parameter value field. By changing the breakpoint value, up or down, the intensity of the bias applied to that breakpoint of the curve is respectively changed. By changing the value of adjacent breakpoints, the effective bias to the shaper can be broadened to suit the desired correction. In the case of multiple false echoes, shaping can be applied along different points of the curve. Shaping should be applied sparingly in order to avoid missing the true echo.

P833 TVT Start Min

Use this feature to adjust the TVT Curve height to ignore false echoes (or pick up true echoes) near the start of the Echo Profile.

Enter the minimum TVT Curve start point (in dB above 1 uV RMS).

This feature should only be used if increased Near Blanking (P800) would extend farther than desired into the measurement range.

Appendix A: Index Types

Index types

1.MultiRanger 100: The two level points are: Transducer One and Trans- ducer Two.

Level point typically has 1 index in Single Point Mode (standard), and 2 indexes in Dual Point Mode (optional).

MultiRanger 200: The three level points are: transducer 1, transducer 2, and the calculated point which can be difference (P001=4) or average (P001=5).

Level point typically has 1 index in Single Point Mode (standard), and 2 indexes in Dual Point Mode (optional). A third index is available in both modes when Operation (P001) is set for DPD (P001=4) or DPA (P001=5).

2.MultiRanger 200: The number of indexes available in Single Point Mode (standard) is typically 1, but can be expanded to 2 if Operation (P001) is set for DPD (P001=4) or DPA (P001=5).

In Dual Point Mode (optional), the number of available indexes is always 2.

Types Index A: Appendix

Appendix B: Tech Reference

Appendix B: Technical Reference

Transmit Pulse

The transmit pulse consists of one or more electrical ???shot??? pulses, which are supplied to the transducer connected to the MultiRanger terminals. The transducer fires an acoustic ???shot??? for each electrical pulse supplied. After each shot is fired, sufficient time is provided for echo (shot reflection) reception before the next (if applicable) shot is fired. After all shots of the transmit pulse are fired, the resultant echoes are processed. The transmit pulse shot number, frequency, duration, delay, and associated measurement range are defined by parameters P803 and P840 to P852.

Echo Processing

Echo processing consists of echo enhancement, true echo selection, and selected echo verification.

Echo Enhancement is achieved by filtering (P821 and P822) and reforming (P823) the echo profile. The true echo (echo reflected by the intended target) is selected when that portion of the echo profile meets the evaluation criteria of Sonic Intelligence??. Insignificant portions of the echo profile outside of the measurement range (Span P006 + Range Extension P801), below the TVT Curve (P830, and P832 to P835), and less than the Confidence Threshold (P804) and Short Shot Floor (P851) are automatically disregarded. The remaining portions of the Echo Profile are evaluated using the Algorithm (P820) and Short Shot Bias (P850). The Echo Profile portion providing the best Echo Confidence (P805) is selected.

True echo verification is automatic. The position (relation in time after transmit) of the new echo is compared to that of the previously accepted echo. When the new echo is within the Echo Lock Window (P713), it is accepted and displays, outputs, and relays are updated per the Fuzz Filter (P710) and Rate Parameters (P700 to P703). If the new echo is outside of the Window, it is not accepted until Echo Lock (P711) requirements are satisfied.

Dolphin Plus Display

TVT (Time Varying Threshold) curves

A TVT curve describes a threshold below which any echoes will be ignored. The default TVT curve is used, until P837 and P838 are used to create a new ???learned TVT curve???.

Auto False-Echo Suppression

False echoes can be caused by an obstruction in the beam path (pipes, ladders, chains, and such). Such false echoes may rise above the default TVT curve.

P838 allows you to set a distance, and P837 then instructs the MultiRanger to ???learn??? where the obstructions/false echoes are within that distance. The new TVT curve is set above the false echoes, screening them out.

Reference Tech B: Appendix

Appendix B: Tech Reference

Distance Calculation

To calculate the transducer to material level (object) distance, the transmission medium (atmosphere) sound velocity (P653) is multiplied by the acoustic transmission to reception time period. This result is divided by 2 to calculate the one way distance.

Distance = Sound Velocity x Time / 2

The Reading displayed is the result of performing any additional modification to the calculated distance (as determined by Operation P001, Units P005, Volume Conversion, P050 to P054, Reading, P060 to P063, OCM, P600 to P611, and/or Totalizer P622 to P633 parameters).

Sound Velocity

The sound velocity of the transmission medium is affected by the type, temperature, and vapor pressure of the gas or vapor present. As preset, the MultiRanger assumes the vessel atmosphere is air at 20??C (68??F). Unless altered, the sound velocity used for the distance calculation is 344.1 m / s (1129 ft / s).

Variable air temperature is automatically compensated when a Siemens Milltronics ultrasonic / temperature transducer is used. If the transducer is exposed to direct sunlight, use a sunshield or a separate TS-3 temperature sensor.

Also, if the temperature varies between the transducer face and the liquid monitored, use a TS-3 temperature sensor (submerged in the liquid) in combination with an ultrasonic / temperature transducer. Set Temp Source (P660) for both, to average the transducer and TS-3 measurements.

Atmosphere composition other than air can pose a challenge for ultrasonic level measurement. However, excellent results may be obtained by performing a Sound Velocity Calibration (P651) if the atmosphere is homogeneous (well mixed), at a fixed temperature, and under consistent vapor pressure.

The MultiRanger automatic temperature compensation is based on the sound velocity / temperature characteristics of ???air??? and may not be suitable for the atmosphere present. If the atmosphere temperature is variable, perform frequent Sound Velocity Calibrations to optimize measurement accuracy.

Sound Velocity calibration frequency may be determined with experience. If the sound velocity in two or more vessels is always similar, future calibrations may be performed on one vessel and the resultant Velocity (P653) entered directly for the other vessel(s).

If the sound velocity of a vessel atmosphere is found to be repeatable at specific temperatures, a chart or curve may be developed. Then, rather than performing a Sound Velocity Calibration each time the vessel temperature changes significantly, the anticipated Velocity (P653) may be entered directly.

Scanning

MultiRanger 100/200

When echo processing is complete (if more than 1 vessel is monitored) the scanning relay changes state to supply the transmit pulse to the other transducer after the Scan Delay (P727).

Scan Delay is automatically set by Maximum Process Speed (P003). When high speed scanning is required (sometimes the case for equipment position monitoring), the Scan Delay may be reduced. Reduce the Scan Delay only as required, otherwise premature scanning relay fatigue could occur.

MultiRanger 200

When two transducers are connected and configured in a dual point unit, the MultiRanger will scan each in turn via the scanner relay. When a single point MultiRanger is programmed for differential or average level Operation (P001 = 4 or 5), two transducers of the same type must be used.

Volume Calculation [MR 200]

Please note that the Volume Calculation feature is only available on the MultiRanger 200.

The unit provides a variety of volume calculation features (P050 to P055).

If the vessel does not match any of the eight preset Tank Shape calculations, a Universal Volume calculation may be used. Use the level/volume graph or chart provided by the vessel fabricator (or create one based on the vessel dimensions). Based on the graph, choose the Universal Volume calculation, and select the level vs. volume breakpoints to be entered (32 max). Generally, the more breakpoints entered, the greater the accuracy.

Universal, Linear (P050 = 9)

This volume calculation creates a piece-wise linear approximation of the level/volume curve. This option provides best results if the curve has sharp angles joining relatively linear sections.

Enter a Level Breakpoint at each point where the level/volume curve bends sharply (2 minimum).

For combination curves (mostly linear but include one or more arcs), enter numerous breakpoints along the arc, for best volume calculation accuracy.

Reference Tech B: Appendix

Appendix B: Tech Reference

Select at least enough breakpoints from the curve to satisfy the following:

???two breakpoints very near the minimum level

???one breakpoint at the tangent points of each arc

???one breakpoint at each arc apex

???two breakpoints very near the maximum level

For combination curves, enter at least two breakpoints immediately before and after any sharp angle (as well as one breakpoint exactly at the angle) on the curve.

Flow Calculation

Please note that the Flow Calculation feature is only available on the MultiRanger 200. The MultiRanger provides numerous OCM flow calculation features (P600 to P611).

If the PMD (primary measuring device) does not match any of the eight preset PMD calculations, or if a PMD is not used, select a Universal Volume calculation. Use the head/ flow graph or chart provided by the PMD fabricator (or create one based on the PMD or channel dimensions).

Based on the graph, choose the Universal Flow calculation, and select the head versus flow breakpoints to be entered (32 max). Generally, the more breakpoints entered, the greater the flow calculation accuracy.

Universal, Linear [MR 200]

Please note that the Universal, Linear feature is only available on the MultiRanger 200.

Set P600 = 4.

This flow calculation creates a piece-wise linear approximation of the head/flow curve. This option provides best results if the curve has sharp angles joining relatively linear sections.

Enter a Head Breakpoint at each point where the head/flow curve bends sharply (2 minimum). For combination curves (mostly linear but include 1 or more arcs), enter numerous breakpoints along the arc, for best flow calculation accuracy.

See also Typical Flow Characterization on page 83.

Universal, Curved [MR 200]

Please note that the Universal, Curved feature is only available on the MultiRanger 200.

This calculation creates a cubic spline approximation of the head/flow curve, providing best results if the curve is non-linear, and there are no sharp angles.

Select at least enough breakpoints from the curve to satisfy the following:

???two breakpoints very near the minimum head

???one breakpoint at the tangent points of each arc

???one breakpoint at each arc apex

???two breakpoints very near the maximum head

Reference Tech B: Appendix

Appendix B: Tech Reference

For combination curves, enter at least 2 breakpoints immediately before and after any sharp angle (as well as 1 breakpoint exactly at the angle) on the curve. For more information, go to Typical Flow Characterization on page 83.

Maximum Process Speed

The MultiRanger???s ability to respond to material level changes is designed to exceed even the most demanding installation requirements.

The Maximum Process Speed setting automatically presets various parameters affecting the MultiRanger response to material level changes as follows:

If any of these parameters are independently altered, a Maximum Process Speed (P003) parameter alteration automatically resets the independently altered value.

Slower Maximum Process Speed (P003) provides greater measurement reliability. Faster, independently set Max Fill (P700) and Max Empty (P701). Rates may be impeded by Echo Lock (P711), Scan Delay (P727), and Shot Delay (P728) values.

Appendix C: Troubleshooting

Noise Problems

Incorrect readings can be the result of noise problems, either acoustic or electrical, in the application.

The noise present at the input to the ultrasonic receiver can be determined by viewing parameter P807. The display reads ##:##, where the first number is the average noise and the second is the peak noise. In general, the most useful value is the average noise.

With no transducer attached the noise is under 5 dB. This is often called the noise floor. If the value with a transducer attached is greater than 5 dB, then signal processing problems can occur. High noise decreases the maximum distance that can be measured. The exact relationship between noise and maximum distance is dependent on the transducer type and the material being measured. Any average noise level greater than 20 dB is probably cause for concern unless the distance is much shorter than the maximum for the transducer.

Determine the Noise Source

Disconnect the transducer from the MultiRanger. If the measured noise is below 5 dB, then continue here. If the measured noise is above 5 dB go to Non-Transducer Noise Sources below.

1.Connect only the shield wire of the transducer to the MultiRanger. If the measured noise is below 5 dB, continue with the next step. If the noise is above 5 dB, go to Common Wiring Problems.

2.Connect the white and black transducer wires to the MultiRanger. Record the average noise.

3.Remove the positive wire of the transducer. Record the average noise.

4.Re-connect the positive wire and remove the negative wire. Record the average

noise.

Using the table below, determine the appropriate next step. The terms higher, lower and unchanged refer to the noise recorded in the previous steps.

These are guidelines only. If the suggested solution does not solve the problem, try the other options also.

Acoustical Noise

To confirm that the problem is acoustical, place several layers of cardboard over the face of the transducer. If the noise is reduced, the noise is definitely acoustical.

Non-Transducer Noise Sources

Remove all input and output cables from the MultiRanger individually while monitoring the noise. If removing a cable reduces the noise, that cable may be picking up noise from adjacent electrical equipment. Check that low voltage cables are not being run adjacent to high voltage cables or near to electrical noise generators such as variable speed drives.

Filtering cables is an option but is not recommended unless all other options have been exhausted.

The MultiRanger is designed to work near heavy industrial equipment such as variable speed drives. Even so, it should not be located near high voltage wires or switch gear.

Try moving the electronics to a different location. Often moving the electronics a few meters farther from the source of noise will fix the problem. Shielding the electronics is also an option, but it should be a last resort. Proper shielding is expensive and is difficult to install properly???the shielding box must enclose the MultiRanger electronics completely, and all wires must be brought to the box through grounded metal conduit.

Common Wiring Problems

???Make sure that the transducer shield wire is connected at the electronics end only. Do not ground it at any other location.

???Do not connect the transducer shield wire to the white wire.

???The exposed transducer shield wire must be as short as possible.

???Connections between the wire supplied with the transducer, and any customer installed extension wire should be done in grounded metal junction boxes.

On Siemens Milltronics transducers the white wire is negative and the black wire is positive. If the extension wire is colored differently, make sure that it is wired consistently.

Extension wire must be shielded twisted pair. Older MultiRanger products may have included recommendations to use co-axial cable for noise reduction purposes. This is no longer the case. Use shielded twisted pair. See the installation section for specifications.

Reducing Electrical Noise

???Ensure that the transducer cable does not run parallel to other cables carrying high voltage or current.

???Move the transducer cable away from noise generators like variable speed drives.

???Put the transducer cable in grounded metal conduit.

???Filter the noise source.

Reducing Acoustical Noise

???Move the transducer away from the noise source.

???Use a stilling well.

???Install a rubber or foam bushing or gasket between the transducer and the mounting surface.

???Relocate or insulate the noise source.

???Change the frequency of the noise. The MultiRanger is only sensitive to noise between 25 KHz and 65 KHz.

Measurement Difficulties

If the Failsafe Timer (P070) expires due to a measurement difficulty, LOE flashes alternately with the last known Reading. In rare cases, the MultiRanger may lock on to a false echo and report a fixed or wrong reading.

Flashing LOE Display

The loss of echo (LOE) display appears when the echo confidence is below the threshold value set in P805 Echo Confidence.

LOE occurs when:

???The echo is lost and no echo is shown above the ambient noise. See low echo confidence (P805) and low echo strength (P806).

???Two echoes are too similar to differentiate. See low echo confidence (P805) and low echo strength (P806).

If LOE is displayed, check the following:

???Surface monitored is within the transducer maximum range

???Transducer model (P004) matches the transducer used

???Transducer is located and aimed properly

???Transducer is not submerged without a submergence shield

Adjust Transducer Aiming

See the transducer manual for range, mounting, and aiming details. For optimum performance, adjust transducer aiming to provide the best Echo Confidence (P805) and Echo Strength (P806) for all material levels within the measurement range.

The most efficient method of checking echoes is with Siemens Milltronics Dolphin Plus software.

Use Dolphin Plus to graphically display the echo profile at the installation. Interpret the echo profile and change relevant parameters.

Edit the parameter values. Use F1 to get online help at any time.

Press (five times or more to verify stability and overcome any echo lock P711).

Increase Failsafe Timer Value

Increase the Failsafe Timer (P070) value, if failsafe operation will not be compromised by the larger value.

Try this only if LOE shows for short periods of time.

Install a Transducer with a Narrower Beam

Sometimes the interference echoes from the sides of a vessel can cause the MultiRanger to lock onto a consistent, incorrect level. Try installing a longer range (narrower beam) transducer, enter the new transducer model (P004), and (if necessary) optimize aiming and frequency again.

Always contact your Siemens Milltronics service personnel before selecting a transducer to solve this type of problem.

Use Dolphin Plus to Debug Echo

If a narrower beam transducer is not available, use Dolphin Plus to view live sonic profiles and make adjustments to the Advanced Echo Processing parameters.

Fixed Reading

If the Reading is a fixed value, regardless of the transducer to material surface distance, ensure the:

1.Transducer acoustic beam is free from obstruction.

2.Transducer is properly aimed

3.Transducer is not in contact with any metal object.

4.Material mixer (if used) is operating while the MultiRanger is operating. If it is stopped, ensure that the mixer blade is not stopped under the transducer.

Obstructions in the Sound Beam

Check for (and remove if present) any acoustic beam obstruction, or relocate the transducer.

If an obstruction cannot be removed or avoided, adjust the Time Varying Threshold (TVT) Curve to reduce the Echo Confidence derived from the sound reflected by the obstruction. Use Dolphin Plus to adjust the TVT curve. (See P832: TVT Shaper.)

Nozzle Mountings

If the transducer is mounted on or in a nozzle, grind smooth any burrs or welds on the inside or open end (the end that opens into the vessel). If the problem persists, install a

Troubleshooting C: Appendix

Appendix C: Troubleshooting

larger diameter or shorter length nozzle, bevel the inside of the bottom end, or cut the open end of the nozzle at a 45?? angle.

See the transducer manual for complete mounting instructions.

For ST-series and XPS-10 transducers use the plastic conduit / flange adapter supplied with the unit.

If the mounting hardware is over tightened, loosen it. Over tightening changes the resonance characteristics of the transducer and can cause problems.

Set the MultiRanger to Ignore the Bad Echo

If the preceding remedies have not fixed the problem, the false echo has to be ignored.

If the Echo is Close to the Transducer

If there is a static, incorrect, high level reading from the MultiRanger there is probably something reflecting a strong echo back to the transducer. If the material level never reaches that point extend the Near Blanking (P800) to a distance to just past the obstruction.

Adjust the TVT to Ignore the Echo

Use Auto False Echo Suppression (P837-P839) to automatically shape around false echoes.

Wrong Reading

If the Reading is erratic, or jumps to some incorrect value periodically, ensure the:

1.Surface monitored is not beyond the MultiRanger???s programmed range or the transducer???s maximum range.

2.Material is not falling into the transducer???s acoustic beam.

3.Material is not inside the blanking distance of the transducer.

Types of Wrong Readings

If a periodic wrong Reading is always the same value, see Fixed Reading.

If the wrong Reading is random, ensure the material surface to transducer distance is less than the Empty value entered plus 20%. If the material/object monitored is outside this distance, increase Range Extension (P801) as required. This error is most common in OCM applications using weirs.

Liquid Splashing

If the material monitored is a liquid, check for splashing in the vessel. Enter a lower Maximum Process Speed (P003) value to stabilize the Reading, or install a stilling well. (Contact Siemens Milltronics or your local distributor.)

Adjust the Echo Algorithm

Use Dolphin Plus to view live sonic profiles and make adjustments to the P820 Algorithm parameter. See P820 on page 204 for details.

If the ???Area??? algorithm is used and narrow noise spikes are evident on the (long shot) Echo Profile, turn the Spike Filter (P821) on and/or widen the Narrow Echo Filter (P822). Also, if the true echo has jagged peaks, use Reform Echo (P823).

Appendix D: Pump Control Reference

Please note that some pump control features apply to the MultiRanger 200 only.

The MultiRanger has the pump control strategies to solve nearly any water / wastewater application. This section details these strategies for engineers requiring in-depth knowledge of the system and how it operates.

Pump Control Options

The various methods of pump control are made up of a combination of two control variables:

Pump Duty

The pump duty indicates in what sequence pumps are started.

Pump Start Method

The start method indicates whether new pumps start and run with any currently running pumps (most common) or whether new pumps start and shut off currently running pumps.

Pump Groups

The MultiRanger groups pumps that use identical pumping strategies based on the value of Relay Control Function (P111). Generally, one group of pumps corresponds to one wet well or reservoir.

Pump by Rate [MR 200]

Please note that this feature applies to the MultiRanger 200 only.

To trigger pump starts by the rate of change in material level use P121???Pump by Rate (P121). New pumps are started, one at a time, until the rate setpoint (Filling Indicator (P702), or Emptying Indicator(P703)) is reached.

Pump Control Algorithms

Please note that the MultiRanger 100 and the MultiRanger 200 use this feature differently.

MultiRanger 100

All of these algorithms can be used to start multiple pumps (assist).

MultiRanger 200

Control Pump D: Appendix

Appendix D: Pump Control

All of these algorithms can be used to start multiple pumps (assist) or one pump at a time (backup).

The MultiRanger 100 and MultiRanger 200 have three main methods of pump control:

Fixed

Starts pumps based on individual setpoints and always starts the same pumps in the same sequence.

Alternate

Starts pumps based on the duty schedule and always leads with a new pump.

Service Ratio

Starts pumps based on user-defined ratio of running time.

Fixed Duty Assist (P111 = 50)

Ties the indexed pump relay directly to the indexed setpoint.

Relay Operation (for P118 = 2)

The relay contact closes at the ON setpoint and opens at the OFF setpoint. Multiple relay contacts in the pump group can be closed at the same time.

Relay Table

The following table shows relay status when each setpoint is reached.

Fixed Duty Backup (P111 = 51) [MR 200]

Ties the indexed pump relay directly to the indexed setpoint.

Please note that this feature applies to the MultiRanger 200 only.

Relay Operation (for P118 = 2)

The relay contact closes at the ON setpoint and opens at the OFF setpoint. When a new relay trips the previously closed relay contact opens to shut down the running pump.

Only one relay contact in the pump group can be closed at any one time.

Relay Table

The following table shows relay status when each setpoint is reached.

Alternate Duty Assist (P111 = 52)

Alternates the lead pump each time the material level cycles and runs all pumps together.

Relay Operation (for P118 = 2)

The setpoints associated with the relays are grouped so that they can be rotated.

Setpoint one does not relate directly to relay one. The pumping algorithm manages the mapping of setpoints to relays.

When pumps are run, they RUN in parallel.

Alternate Duty Backup (P111 = 53) [MR 200]

Alternates the lead pump each time the material level cycles.

Please note that this feature applies to the MultiRanger 200 only.

Relay Operation (for P118 = 2)

The setpoints associated with the relays are grouped so that they can be rotated. Setpoint one does not relate directly to relay one. The pumping algorithm manages the mapping of setpoints to relays. When pumps are run, they can RUN only one at a time.

Control Pump D: Appendix

Appendix D: Pump Control

Service Ratio Duty Assist (P111 = 54) [MR 200]

Selects the lead pump based on number of hours each pump has run and the specified ratios that each pump requires.Multiple pumps can run at one time.

Please note that this feature applies to the MultiRanger 200 only.

Relay Operation (for P118 = 2) [MR 200]

Please note that this feature applies to the MultiRanger 200 only.

The setpoints associated with the relays are grouped so they can be redistributed based on pump RUN time ratios. The next pump to start or stop is the one with the required time to actual time ratio.

Over time the number of hours demanded of each pump will conform to the ratios specified. Usually, the ratios are specified in percent values.

To create a grouping of pumps where two pumps make up 50% of the run time and the third pump makes up the other 50%.

P122 is set to these values:

Service Ratio Duty Backup (P111 = 55) [MR 200]

Selects the lead pump based on number of hours each pump has RUN and the specified ratios that each pump requires.Only one pump can RUN at a time.

Please note that this feature applies to the MultiRanger 200 only.

This algorithm is the same as Service Ratio Duty Assist except that it will only RUN one pump at a time. When the next pump in the sequence starts, the previous pump stops.

First In First Out (FIFO) (P111 = 56) [MR 200]

Selects the lead pump based on the Alternate duty but uses staggered off setpoints and shuts down pumps based on the first in, first out rule.

Please note that this feature applies to the MultiRanger 200 only.

This algorithm starts pumps in the same way as Alternate Duty Assist but uses staggered OFF setpoints to shut the pumps down. When the first OFF setpoint is reached the FIFO rule shuts down the first pump started. If the pumps started in sequence 2,3,1 then they would be shut down in sequence 2,3,1.

Pump by Rate (P121) [MR 200]

Starts pumps until the level is changing at the rate specified in P702 or P703.

Please note that this feature applies to the MultiRanger 200 only.

Pumping costs can be less because only the highest ON setpoint needs to be programmed and this results in a lower difference in head to the next wet well which, in turn, results in less energy being used to pump out the well.

Other Pump Controls [MR 200]

Please note that these features apply to the MultiRanger 200 only.

There are a number of other controls available to modify pump behaviour.

Pump Run-On (P130, P131)

Extends the RUN period for a pump based on a set time interval. This allows for the wet well to be pumped lower than usual and reduces sludge build-up on the well bottom.

Wall Cling Reduction (P136)

Varies the ON and OFF setpoints to keep a fat ring from forming around the walls of the wet well.

Pump Group (P137)

Allows for two different Alternate Duty Assist or Alternate Duty Backup pump groups in the same application.

Appendix F: Upgrading

Appendix F: Upgrading

The following procedure will assist you if you are upgrading from a MultiRanger Plus to a MultiRanger 100 or MultiRanger 200.

If the application is unchanged, copy down the parameters in the MultiRanger Plus before de-commissioning the unit.

Mounting a MultiRanger 100/200

Please read the MultiRanger Installation section on page 8 before mounting the new MultiRanger 100/200.

Make sure the power is OFF to the unit before following these steps:

1.Remove the old MultiRanger Plus.

2.Mount the new MultiRanger 100/200 using the same mounting holes.

Connecting the Transducer

Important: Unlike the MultiRanger Plus, coaxial cable is not recommended for use with the MultiRanger 100/200 for transducer cable extensions. The MultiRanger 100/200 circuit is designed to use shielded twisted pair cable. Ideally, the coaxial cable should be replaced with twisted pair.

If this is not practical, please refer to the Coaxial Transducer Extension section below.

Coaxial Transducer Extention

The MultiRanger 100/200 uses a new differential input receiver that works either directly connected to the transducer lead or with a screened twisted pair extension cable via a field junction box. This arrangement, using two conductors and a screen, gives considerably better electrical noise immunity than the previous coaxial arrangement (up to 20dB) and will give reliable operation in applications where the proximity of power cables, variable speed drives etc. would have caused problems.

If you are installing a new MultiRanger system we strongly recommend that you use a good quality screened, twisted pair cable if an extension is required. If the integral transducer cable is used you need only connect to the MultiRanger and benefit from the superior performance.

Connecting a transducer with RG62 coaxial extension cable

If you are replacing an older Siemens Milltronics Ultrasonic Level Controller with a new MultiRanger where an RG62 coaxial extension is fitted and you are unable to replace the extension with a new cable, please refer to connection diagram below. Please note that the noise immunity performance will be similar to our older model ultrasonic level controllers if you use coaxial cable.

Existing installation

RG62 coaxial cable has been used to make the extension. The level controller might be a MultiRanger Plus, HydroRanger, HydroRanger Plus or one of our other level controllers.

Upgrading F: Appendix

Appendix F: Upgrading

MultiRanger Plus to MultiRanger 100/200 Parameters

The MultiRanger 100/200 uses the current Siemens Milltronics standard parameter set which is different than the parameter numbers used in the MultiRanger Plus.

The MultiRanger Plus parameters numbers are sequential (P-0 to P-99). The MultiRanger 100/200 parameters number are also sequential; however, some of the parameters are indexed.

Parameters are indexed when they apply to more than one input or output. The index value defines the input/output for that parameter. Indexed parameters contain a value for each index, even if that index is not used.

Example

In the MultiRanger Plus each relay had a dedicated parameter number for its function, ON and OFF points.

MultiRanger Plus Relay One

???P-8: Function

???P-9 : ON setpoint

???P-10: OFF setpoint

MultiRanger 100/200 uses P111 for all relays and indexes these parameters.

???P-111: Function

???P-112: ON

???P-113: OFF

The following tables show the differences between the MultiRanger Plus and the MultiRanger 100/200. They each show one relay programmed as a high alarm, and two relays programmed for pump control with alternating pump starts:
