Automatic Bypass The Automatic Bypass consists of a static
Inverter to Utility.
This protection works automatically by opening contactor K6 and K8 (in series with the thyristors of the static switch) and eventually K7, and acts in case of internal defects of the system, or due to wrong manipulations on the Manual Bypass Q2.
Manual Bypass The Manual Bypass consists of a pair of manual switches (Q1 and Q2), which removes the UPS from the Load for maintenance, while still supplying the Load with power directly from the Utility.
BatteryThe Battery supplies the DC power to the Inverter when the Utility is out of accepted tolerances.
g
GE
3.2OPERATION MODES
3.2.1 Normal operation mode
During normal operation, the Rectifier converts input AC power to DC.
The DC power provides input power for the Inverter and charging power for the Battery. The Inverter converts the DC power to continuous and regulated AC power, which supplies the critical load.
The control panel reports the Battery charge status and the expected backup time with the actual load.
3.2.2 Utility failure operation
When the Utility is no longer within acceptable tolerances, the Battery will provide the DC power to the Inverter.
The Inverter will maintain continuous AC power to the Load until the Battery Voltage reaches the lower limit of the Inverter operation capability.
During the discharge, the LCD screen displays the estimated time the Battery can support the critical load.
Prior to the Battery completely discharging, the "stop operation" alarm (shutdown imminent) warns the operator that the Battery is almost discharged and the UPS is about to shut down.
Fig.
Fig.
In case of parallel operation
With a parallel system for power capacity (see Section 3.3)
???With the Bypass Utility power available, a low Battery warning on any unit will cause the Load to be transferred to Utility (after a selectable time delay).
???With Bypass Utility power not available, a low Battery warning on any unit will start the ???stop operation??? timer (adjustable).
The Load will shut down at the end of the ???stop operation??? time period.
With a parallel system for redundancy (see Section 3.3)
???When a Battery low warning occurs on a unit not necessary to support the present load, this unit will shut down after a timeout period (selectable).
The Load is shared between the other units
???As the warning occurs on one unit necessary to support the present load, the system starts the "stop operation" timeout (selectable).
The Load will shut down at the end of the ???stop operation??? time period.
g
GE
3.2.3Utility recovery operation
As soon as the AC input power recovers, the
Rectifier will start automatically, supplying DC power to the Inverter and recharging the Battery.
If the Inverter was previously shut down due to low Battery, the Load will be initially powered by Utility through the Automatic Bypass.
When the Battery is recharged enough to ensure a minimum time of operation with the present load, the Inverter will start automatically and the Load will be transferred back to the Inverter.
Fig.
In case of parallel operation
When the AC input power recovers, the Rectifiers will start up sequentially, according to their number in the parallel system. This minimizes the initial inrush current.
The Inverters will start up automatically, but only when the Battery has recharged enough for a minimum runtime with the present load.
When enough Inverters to supply the Load have been restarted, the Load will be transferred from the Automatic Bypass back to the Inverter output.
3.2.4 Automatic Bypass
In normal operation, the Load is supplied by the
Inverter.
When the control system detects a fault in the Inverter, an overload condition or a
When the Inverter recovers, or the overload or
If the UPS is unable to return to normal mode following an automatic transfer to Bypass mode, an alarm condition will be initiated.
A Manual Bypass (operator initiated) will not be considered as an alarm condition.
FIG.
BYPASS
In case of parallel operation
Each unit has it???s own internal Bypass. These units are continuously exchanging information, enabling all of the internal Bypass circuits in a parallel system to operate simultaneously.
If the Inverter of a unit fails, it???s Bypass circuit remains available to the parallel system.
It is excluded only if the unit is separated from the common bus by opening it???s output switch Q1.
3.2.5Manual Bypass
The Manual Bypass circuit consists of Q1 and Q2 manual switches, which permits transfer of the Load directly to the unconditioned AC power without interruption, leaving the UPS available for maintenance.

3.3PARALLEL SYSTEM OPERATION
3.3.1 Introduction to the parallel system
Two or more equal power units can be paralleled to increase the output power (paralleling for capacity) or to improve the overall reliability of an UPS system (paralleling for redundancy). The outputs of parallel units are connected to a common power bus, and in normal operation the units connected on the parallel bus share the Load equally.
The modular concept of SG Series allows parallel operation of up to 8 units, without using paralleling switchgear, external bypass circuits or common control circuitry (see Fig.
Parallel units for power capacity
Several units can be paralleled in order to achieve output power greater than the maximum power of a single unit.
The maximum total power shared between the paralleled units is equal to the total installed nominal power.
In the event of a failure of one unit, the power supplied by the UPS system becomes insufficient and the Load will be transferred to the Utility Bypass source.
Parallel units for redundancy
The nominal power rating of the n+1 out of n redundant paralleled modules must be equal to or greater than the required Load power.
The Load will be equally shared by the n units connected on the output bus.
Should one of the n paralleled units trip
From this results higher reliability and security for the Load plus a higher MTBF (Mean Time Between Failures).

GE
3.3.2 Features of RPA parallel system
The SG Series parallel system is designed to provide a complete Redundant Parallel Architecture, and is free from common equipment.
Not only the Inverters are redundant, but also the Bypass functions are designed with redundant modular concept.
When one UPS needs maintenance or service, the Load is powered by the other units supplying the Load bus.
The redundant communication bus to which all units are connected keeps each unit informed about the status of all the other units.
The control panel located on each unit allows controlling and monitoring the status of this unit.
3.3.3 System control
A
Each module controls it's own function and operational status and communicates with all other modules, in order to act or react if necessary, adapting it to the new conditions.
3.3.4 Synchronization
All units are identical, but one unit is arbitrarily selected as the reference and all the other units synchronize to this unit, which in turn, synchronizes to the Utility Bypass voltage, as long as the later is within tolerances.
In case of reference failure, another unit in the parallel system is automatically chosen to take over the reference role.
The Bypass Input for all the units of the parallel system must be supplied from the same AC source (no phase shift allowed between them).
3.3.5 Load sharing
On each unit of the parallel system, Inverter Output Voltage and Current are measured and applied to a Load sharing bus.
An eventual difference between the units is therefore automatically equalized.
It is strongly recommended that no transformers, automatic circuit breakers or fuses should be inserted between the unit???s output and the Load common bus bars.
However, it is recommended that a disconnect or isolation switch be inserted.

???The installation must be performed only with the UPS system must be completely shut down.
???The AC Rectifiers input power (5) must be the same, with clockwise phase rotation for each unit.
???Each Rectifier must be set for the same floating DC voltage and the same Battery current limitation.
???It is recommended to install the fuses / MCB (7) on each line connecting the Rectifiers to the common Battery for maintenance / safety reasons.
???In case one must be powered down for maintenance,
???It is recommended to connect an external NO free contact ???Battery Fuses??? to the UPS and to enable the function by setting the parameter (see Section 7.1).
???If an emergency generator set supply the UPS, and the free contact ???Generator ON??? is connected to the Customer interface, connect a separate NO free contact on each parallel unit.
???The parameters enabling the Battery test, both manual and automatic, must be set in the same mode on all the units having the Rectifiers on Common Battery.
???Do not connect the temperature sensor for automatic battery floating voltage compensation.
???Do not enable the function Boost charge (parameter 87).

Type 3: Boolean parameters used to simulate command buttons.
The Boolean parameters have a range of Yes/No.
Only the user performs the modification of the value.
These ???Type 3??? parameters are used to initiate an action. There are two possibilities:
A1 ??? the user wants the UPS to start the action => the user sets the parameter to ???Yes???. 2 ??? the UPS finishes the action => the UPS sets the parameter to ???No???.
B1 ??? the user wants the UPS to start the action => the user sets the parameter to ???Yes???. 2 ??? the user wants to abort the action => the user sets the parameter to ???No???.
The actions that can be performed using such software buttons are:
???Print the metering information.
???Print the last 256 events.
???Print the values of the parameters.
???Print all the information obtainable from the UPS.
Returning from the Edit mode
Normally ok button is used to return from the Edit mode.
Then the UPS will perform some validity tests on the new value.
If these tests are successful then the new value is saved and used.
If these tests fail the Edit mode is not exited.

Some programmable UPS functions (indicated in Section 4.1), can be activated by closing an external contact, if connected, on:
8.1.4 Gen Set Signaling (GEN ON)
If an emergency generator set supplies the UPS in case of Utility Failure and the generator is particularly unstable in frequency, it should be suitable to install the signal ???Generator ON??? on X1/11, 22 or J2/11, 24 (this input is programmed as default for this function).
When this contact closes, it causes the change of certain functions (programmable) such as:
???Enabling or disabling of synchronization and consequently the Load transfer to generator.
???Reduction or elimination or delay of Battery recharging during the generator operation.
In a parallel system a separate NO (Normally Open) contact must be connected individually to each unit.
8.1.5AUX external Maintenance Bypass
If the UPS system is equipped with an external Maintenance Bypass Switch, it is possible to connect a NO (normally open) voltage free aux. contact from the External Bypass Switch to the programmable input
This function can be activated by changing a dedicated parameter (password required).

10 MAINTENANCE
GE
10.1MAINTENANCE
A UPS system, like other electrical equipment, needs periodic preventive maintenance.
A regular maintenance check of your installation guarantees higher reliability of your safe critical power supply.
Preventive maintenance work on the UPS can be done only by trained Service technicians.
We therefore recommend you sign a Maintenance and Service contract with GE Global Services @
10.1.1 Service check
If this lamp lights up during the normal operation, that means that the unit has not been serviced for the last 20,000 hours by a GE trained technician.
We highly recommend that you contact your Service Center for preventive maintenance work.
10.1.2 Fans and ventilation
We recommend a periodic cleaning of the ventilation channels and grids on the UPS system, in order to guarantee proper air circulation in the unit and in the Battery.
We recommend replacement of the fans in the units every 20,000 hours.
10.1.3 Other components with limited lifetime
We recommend the replacement of components such as Filter Capacitors and Lithium Battery for the backup of data on the control boards of the units every 50,000 hours.
10.1.4 Battery
We recommend a periodic Manual Battery Test, especially if the Automatic Battery Test is disabled, in order to verify if the Battery can provide the expected backup time in case of Utility Failure.
We recommend this test be performed at least every 3 months, especially if the Battery is not sufficiently discharged during normal operation.
The discharge time you use should be at least half of the Battery runtime.
For Automatic Battery Test setting, a special code is required to enter user
Please consider that, if you did a full Battery Test to verify the full runtime of the Battery, the charger needs at least 8 hours to recharge the Battery up to 90% of its capacity.
g
GE
10.1.5 Long
To guarantee that the Battery is fully charged, the UPS system should be in operation for at least
12 hours every 3 months.
If not the Battery may be permanently damaged.
