The normal operating screen displays the information as shown in Figure 2.

The Honeywell EC-P2 is designed to avoid accidental shut-off of the power. To turn the unit off, the PWR button must be held down for approximately three seconds. Release the button after the ???Power Down??? message appears.

2.2 Changing the Target Gas using SMART-CELL Technology

The Honeywell EC-P2 can easily be changed to sense another target gas by installing the SMART-CELL for the desired target gas. Each SMART-CELL contains all the calibration and alarm setpoint information on its internal memory chip, so recalibration or reprogramming is not necessary when changing the Honeywell EC-P2 from one gas to another. This procedure can be performed with the unit powered on or off (see Figure 3).

1.Unscrew the two stainless steel thumbscrews and remove the black inlet / outlet manifold lid from the back of the unit.

2.To remove the existing SMART-CELL, grip the sides of the cell and pull it straight out.

3.Install the desired SMART-CELL by gently inserting it into the socket. Notice that the SMART-CELL is keyed so it cannot be inserted incorrectly.

4.Replace the manifold and hand tighten the thumbscrews.

5.Verify proper flow through the sampling wand using the flowmeter provided.

Note:

Extra SMART-CELLS should be kept on the optional sensor keeper when not in use to keep them ???warmed up??? and ready for immediate use. The sensor keeper is powered by an Alkaline ???D??? size battery which should be replaced every 6 months.

For a variety of target gases, see page 19 for a list of available SMART-CELLs. Contact Honeywell Analytics if the desired target gas is not listed, as new cells may be available.

2.3 Response Test

Prior to use, the unit should first be tested for proper response. With the detector operating, the unit should be exposed to a sample of the target gas.The display should show an increasing concentration. If not, do not use it for field measurements.

2.4 Sample Inlet Port

The Honeywell EC-P2 is provided with a quick disconnect flexible extension wand. It will work with or without the wand. When using the extension wand, the internal walls must be kept dry. Water on the walls of the tubing can potentially absorb the target gas. To dry, allow the unit to pump dry, ambient air for 15 minutes.

2.5 Response/Recovery Time

Under normal conditions, the instrument will reach 90% of final value within two minutes. This is dependent on concentration and temperature.

Recovery time for the sensor depends on duration and concentration of exposure. Short exposures of concentrations at the lower end of the target gas range result in rapid recovery. Long exposures to levels above the middle of the target gas range or short exposures to levels exceeding the target gas range can extend recovery times to hours. Repeated exposures above the target gas range will reduce cell life and should be avoided.

3 Maintenance

3.1 Periodic Maintenance

It is essential that the test and calibration schedule be adhered to. Honeywell Analytics recommends the following maintenance schedule:

???Response test prior to each use. Expose sensor to a sample of the target gas to verify proper sensor response and alarm functions.

???Calibration should be performed with certified calibration gas every six months, and all tests must be logged.

???Check filter material every six months. Replace if dirty or moist.

???If the optional sensor keeper is used for extra SMART-CELLs, change the sensor keeper battery once every 6 months. Use only alkaline ???D??? size batteries.

3.2Sensor Life

The electrochemical SMART CELL is extremely reliable, but the following can cause the cell chemicals to become depleted:

???A period of time

???Exposure to high temperatures

???Exposure to high concentrations of the target gas

???Exposure to high moisture

When the cell becomes depleted, the unit will give no indication of failure other than that the sensor will not respond. For this reason it is absolutely essential that these units be exercised with a gas sample on a regular basis.

Typical sensor life under normal use is two years or more.When the SMART-CELL will no longer calibrate properly, simply purchase a new SMART-CELL and replace.

3.3 Calibration

Calibration is recommended every six months in normal use. Each SMART-CELL stores its calibration and alarm setpoint information on its own memory chip. When the SMART-CELL is plugged into the Honeywell EC-P2, this information is used by the sensor. The SMART-CELL can be field calibrated by the user or returned to Honeywell Analytics for factory calibration.

The calibration procedure requires the use of a bypass tee to allow the gas to be drawn into the flow cell without creating variable pressure or dilution problems. Calibration gas cannot be fed into the flow cell under pressure.

When applying calibration gas use the bypass tee as shown in Figure 4 on page 11. The flowrate of calibration gas should be high enough that at least 0.5 SCFH is flowing out of the calibration tee.This can be measured with the supplied flowmeter and insures that air is not being drawn into the unit and diluting the calibration gas.

Note:

The unit may be zeroed without spanning it; however, never span the unit without first zeroing it.

The following procedure will calibrate the SMART-CELL.

To Enter ZERO / SPAN Mode

1.Push power button to turn unit on. Wait for power up sequence to finish (30 seconds).

2.Push and hold the unnamed button (second from left) first, then Push and hold the Menu button. Hold both buttons until the screen goes blank (2 seconds). Release both buttons and the unit is now in Programming Mode.

3.Push the SENS button and the unit is now in the zero/span mode.

Zero Calibration

4.Be sure the unit is in clean air or apply zero air for two minutes.

5.Push ZERO button.

6.Push SAVE button to save the new zero calibration.

Span Calibration

7.Push SPAN button.

8.Apply span gas for two minutes.

9.Push INC button (increase) or DEC button (decrease) until the display matches the span gas concentration.

10.Push SAVE button to store new span calibration.

To Exit ZERO / SPAN Mode

11.Push DONE button twice slowly to get back into normal operation mode.

3.4Troubleshooting

The detector does not start: Check to see that a fresh battery is installed. Both the primary and standby batteries must be discharged for this problem to occur. Plug the charger into the Honeywell EC-P2 to charge the standby battery. Wait 10 minutes and retry.

The detector does not respond to the target gas: Verify the proper flow rate using the supplied flowmeter. Perform calibration. If sensor won???t calibrate, the SMART-CELL may be depleted. Contact Honeywell Analytics for a replacement

SMART-CELL.

Pump alarm: This will occur if the pump motor stops or if an internal pressure sensor detects blockage of the inlet. Check that the internal filter is not clogged or wet and that the inlet tube is clear.

External flowmeter indicates no flow: Verify that pump is running. Check that the manifold screws are tight and the extension wand connection is tight.

Unit does not respond when keys are pressed: Press and hold all four buttons for five seconds. This will reset the Honeywell EC-P2. Turn the unit back on by pressing the PWR button.

High reading won???t clear: When the sensor is exposed to very high gas concentrations, it takes a relatively long time for the sensor to clear. Leave the unit running in a clean environment for a few hours to clear the sensor. If it doesn???t clear after six hours, the sensor may have been damaged. Contact Honeywell Analytics for a replacement SMART-CELL.

Unit is in alarm with gas reading of 0 ppm: Check the alarm setpoints and alarm functions as described on page 12. Verify that alarm is not programmed as a downscale alarm, and that the setpoint is above zero.

4 Programming and Advanced Features

4.1 Alarm Setpoints, Functions

The Honeywell EC-P2 has three adjustable alarm setpoints. These setpoints are stored on each SMART-CELL. The Caution setpoint is to warn of excessive negative zero drift. The WARNING and ALARM setpoints are to warn of potentially dangerous target gas concentrations. The following procedure will change the WARNING setpoint.

To Enter CAUT / WARN / ALRM Mode

1.Push power button to turn unit on. Wait for power up sequence to finish (30 seconds).

2.Push and hold the unnamed button first, then Push and hold the Menu button. Hold both buttons until the screen goes blank (two seconds). Release both buttons and the unit is now in Programming Mode.

3.Push the ALRM button and the unit is now in the CAUT / WARN / ALRM mode.

Warning Setpoint

4.Push WARN button.

5.Push S.P. button (setpoint).

6.Push INC button (increase) or DEC button (decrease) until the display matches the desired warning setpoint. Notice the minus sign above the arrow if the setpoint is below zero.

7.Push SAVE button to store new warning setpoint.

8.Push DONE button to return to Alarms mode.

To Exit CAUT / WARN / ALRM Mode

9. Push DONE button twice slowly to get back into normal operation mode.

The Caution and Alarm setpoints are programmed in the same manner, except for step four above in which you would push either the CAUT or ALRM button. The function of each alarm can be selected to alarm on increasing gas concentration (UP arrow), alarm on decreasing gas concentration (DOWN arrow), or be disabled (off). The following procedure will set the Warning function to alarm on decreasing concentration (Useful for Oxygen Depletion warning).

To Enter CAUT / WARN / ALRM Mode

1.Push power button to turn unit on. Wait for power up sequence to finish (30 seconds).

2.Push and hold the unnamed button first, then Push and hold the Menu button. Hold both buttons until the screen goes blank (two seconds). Release both buttons and the unit is now in Programming Mode.

3.Push the ALRMS button and the unit is now in the CAUT / WARN / ALRM mode.

Warning Function

4.Push WARN button.

5.Push FUNC (function) button.

6.Push SELECT button while viewing the arrow in the lower left hand corner of the screen to toggle through the following three possibilities:

???UP arrow ??? Warn on increasing concentration (gas goes higher than setpoint).

???DOWN arrow ??? Warn on decreasing concentration (gas goes lower than setpoint).

???Blank ??? warning function turned OFF.

7.Push SAVE button when the DOWN arrow is displayed to store new warning function.

8.Push DONE button to return to Alarms mode.

To Exit CAUT / WARN / ALRM Mode

9.Push DONE button two times slowly to get back into normal operation mode.

The Caution and Alarm functions are programmed in the same manner, except for step four above in which you would push either the CAUT or ALRM button.

4.2 Display Variables

The Honeywell EC-P2 has two adjustable display variables.These variables control signal conditioning of the LCD display. Variables are stored on each SMART-CELL. The AVG (Average) variable determines the number of one second samples to average to calculate the displayed value. The lower the averaging value, the faster the display will change and the more ???wiggle??? will be displayed. The BLANK (zero blanking) variable controls the lowest reading that will be displayed. This is to eliminate the misleading display of signals within the zero noise of the sensor. The following procedure will change the AVG variable.

To Enter AVG / BLANK Mode

1.Push power button to turn unit on. Wait for power up sequence to finish (30 seconds).

2.Push and hold the unnamed button first, then Push and hold the Menu button. Hold both buttons until the screen goes blank (two seconds). Release both buttons and the unit is now in Programming Mode.

3.Push the MORE button.

4.Push the DISP (display) button and the unit is now in the AVG / BLANK mode.

AVG Variable

5.Push AVG button.

6.Push INC button (increase) or DEC button (decrease) until the display matches the desired value.

7.Push SAVE button to store new AVG variable.

To Exit AVG / BLANK Mode

8. Push DONE button twice slowly to get back into normal operation mode.

The Blanking variable is programmed in the same manner, except for step 5 above in which you would push the BLANK button.

4.3 Sample Mode

The Sample Mode feature allows the user to take a measurement using a predefined repeatable method to eliminate user ???interpretation??? of a gas concentration that is changing. This is similar to a digital scale, for example, so the exact same reading will be taken regardless of who is taking it.

The measuring sequence used in Sample Mode is as follows:

???Draw a Sample for a user programmed sampling time to allow unit to stabilize to the existing gas concentration.

???Measure the gas concentration and average it for a user programmed measuring time.

???Clear the gas concentration to below a user programmed recovery value before allowing another cycle to start. (Unit should be moved to fresh air during the clear time.)

Taking a sample

To take a sample, locate the detector at the desired sample location, and push the SMPL (sample) button on the normal operation screen. The unit will count down the Sample time, followed by the Measure time, at the end of which the average value will be displayed.

Note the displayed sample value. Pushing the CLEAR button will return the unit to the normal operation screen once the gas concentration is below the predefined recovery value. The unit is now ready to take another sample if desired.

Programming sample mode variables

The sample mode variables are Sample, Measure and Clear as described above. The following procedure will change the Sample variable.

To Enter SAMP / MEAS / CLEAR Mode

1.Push power button to turn unit on. Wait for power up sequence to finish (30 seconds).

2.Push and hold the unnamed button (second from left) first, then Push and hold the Menu button. Hold both buttons until the screen goes blank (two seconds). Release both buttons and the unit is now in Programming Mode.

3.Push the MORE button.

4.Push the SMPL (sample) button and the unit is now in the SAMP / MEAS / CLEAR mode.

SAMP Variable

5.Push SAMP (sample) button.

6.Push INC button (increase) or DEC button (decrease) until the display matches the desired value. The display is in minutes and seconds.

7.Push SAVE button to store new SAMP variable.

To Exit SAMP / MEAS / CLEAR Mode

8. Push DONE button twice slowly to get back into normal operation mode.

The Measure and Clear variables are programmed in the same manner, except for step five above in which you would push the MEAS or CLEAR button.

4.4 Data Logging

The Honeywell EC-P2 can log periodic gas concentration readings to be downloaded to a file which can be read by Microsoft Excel or other popular spreadsheet applications.The EC-P2 will store instantaneous gas values every one, five, 10, or 15 minutes. Multiple sessions can be logged and then downloaded as separate files.

EC-P2 software installation:

The Honeywell EC-P2 is supplied with a CD containing the ???Honeywell EC-P2??? program. It will run on Windows 98, Windows 2000 or Windows XP. To install the program, place the disk in your CD drive. The CD should automatically begin the installation process. Follow the prompts as they appear on your screen. Accepting the default directory locations is recommended for most installations. If the CD does not automatically start, click on ???My Computer??? and then your CD drive. Double-click on the file named ???Setup.exe.???

Prior to your first datalogging session it is recommended that you connect the Honeywell EC-P2 to your computer with the data logging program running. The computer can then set the time in the EC-P2 to match its own clock.

Data Logging with the Honeywell EC-P2:

To Start the Data Logging Session

1.Push power button to turn unit on. Wait for power up sequence to finish (30 seconds).

2.Push the MENU button.

3.Push the LOG button and the unit is now in the CLEAR / INT / START mode.

4.If the CLEAR button is available, that means there is data currently stored in the unit. If desired, you can erase the data already in the unit by pushing the CLEAR button. (If you don???t push CLEAR, each data logging session can be downloaded as a separate file).

Each SMARTCELL has a wide range of choices of full scale values.

Note:

The full scale range as programmed below only affects the analog output and the data logging full-scale output.

The display will always cover the entire operating range of the SMART-CELL. Changing the range can affect the display resolution for some SMART-CELLs.

Changing the full scale range on EC-P2:

To Enter RANGE Mode

1.Push power button to turn unit on. Wait for power up sequence to finish (30 seconds).

2.Push and hold the unnamed button (second from left) first, then Push and hold the MENU button. Hold both buttons until the screen goes blank (two seconds). Release both buttons and the unit is now in Programming Mode.

3.Push the MORE button.

4.Push the DISP (display) button.

5.Push the MORE button and the unit is now in the RANGE mode.

Adjusting the RANGE

6.Push RANGE button.

7.Push INC button (increase) or DEC button (decrease) until the display matches the desired full scale range.

8.Push SAVE button to store new full scale range.

To Exit RANGE Mode

9. Push DONE button twice slowly to get back into normal operation mode.

Appendix A

Available SMART-CELLs

Notes:

1.None means there is no interference.

2.A number indicates that when exposed to the interference gas, the sensor will react the specified amount for a given concentration. For example,

on the first line of the table above, if the NO2 sensor is exposed to 1 ppm Bromine (Br2), the sensor will read 0.5 ppm.This interference is in addition to the target gas present.

For example, if an NH3 sensor is exposed to 1 ppm NH3 and 1 ppm Br2 at the same time, the reading will be 0.9 ppm
