2 INTRODUCTION

An Uninterruptible Power Supply (UPS) provides the power for critical loads that need a reliable, continuous, disturbance free supply.

In case the power provided by the Utility Fails, or exceeds the permitted tolerances, the power to supply the Load is provided by the Battery for the specified time at the rated Load (or longer at a reduced Load) or until the Utility power returns.

SG Series is a true double conversion On-line UPS system where the Load is continuously supplied by the Inverter through the Rectifier.

In case of trouble on the Inverter Output Voltage, or when overload or short-circuit on the output occur, the Load is instantly transferred to the Utility via the Automatic Bypass.

The UPS automatically returns to normal mode when the failure condition is restored.

Key features

• More Critical equipment supported

Rated at 0.8 Power Factor, SG Series delivers more real power than other UPS in the market. With today’s trend toward power factor corrected loads, SG Series can support more total Load than any other UPS available, allowing you to support a greater number of today’s enterprise computing Power Factor Corrected (PFC) equipment.

• No single point of failure

Redundant Parallel Architecture (RPA) is an exclusive GE technology. With RPA, SG Series UPS are controlled in a true peer-to-peer configuration where all critical elements and functions (including Bypass) are redundant. SG Series is designed to be the most reliable power protection system available on the market today.

• High Efficiency

Using IGBT technology and Space Vector Modulation (SVM) strategy, SG Series offers low output voltage distortion and provides efficiencies up to 93%.

• Fully digital

Digital Signal Processor (DSP), Flash memory and SVM strategy, are the technology corner stones of new age of power quality and power reliability.

3 DESCRIPTION

3.1 BLOCK DIAGRAM AND MAIN ELEMENTS

The SG Series system can be divided into the following main elements:

Fig. 3.1-1 Block diagram

Control System SG Series is designed with microprocessor-controlled signal processing circuits. The interface between the operator and the unit is provided by the monitoring system on the front panel. This monitoring system consists of an active mimic diagram, a keyboard and a backlit display.

Rectifier The standard Rectifier consists of a 6-pulse SCR-bridge, which converts the 3-phase Utility Voltage into a controlled and regulated DC-voltage. This regulated DC-voltage is used to supply power to the Inverter, and to provide charging power to the Battery.

Inverter

The Inverter converts the DC voltage into a three-phase ACvoltage with constant amplitude and frequency, which is completely independent and isolated from the AC-input voltage.

Automatic Bypass The Automatic Bypass consists of a static semiconductor-switch (SSM: Static Switch Module), used to provide an uninterrupted transfer of the Load from Inverter to Utility.

Back-feed Protection

All SG Series UPS's are equipped with an automatic system for the protection against voltage back feeding towards Utility, through the Bypass (Applied Standard IEC 62040-1). 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

SG Series

10, 20, 30 & 40 kVA

3.2 OPERATION 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.

initial inrush current.

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 short-circuit condition, the Automatic Bypass will transfer the critical Load to the Utility without interruption. When the Inverter recovers, or the overload or short-circuit condition is corrected, the Load will be automatically transferred back to the Inverter. 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.

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.

3.2.5 Manual Bypass

3.3 PARALLEL 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 paralleling switchgear, external bypass circuits or common control circuitry (see Fig. 3.3.1-1).

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 or greater than the required The Load will be equally shared by the n Should one of the n the load, maintaining conditioned power to the critical load. From this results higher reliability and security for the Load plus a higher MTBF (Mean Time Between Failures).

3.3.2 Features of RPA parallel system

The SG Series parallel system is designed to provide a complete

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

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.

bus guarantees the exchange of data and

Redundant Parallel

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.

3.4 RECTIFIERS PARALLELED ON THE SAME BATTERY

A parallel system with a Common Battery for two or more Rectifiers, requires a particular installation and adequate setting of some parameters, (accessible only through password), and can therefore only be done by a qualified engineer from GE.

Usually each Rectifier-Inverter Unit runs with its own Battery. In case of parallel units are running with a Common Battery (max. 4 UPS - see Fig 4.12-1), the sharing circuit between individual Rectifier is integrated in the communication bus of the system in order to assure an equal sharing of the Rectifiers output currents.

• The units delivered for this functioning mode needs a special parameters setting, so they

must be prepared in advance before the installation.

• 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

• In case one must be powered down for maintenance, switch-OFF the concerned unit before

open the DC fuses / MCB on the Battery line (7).

• 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:

A 1 – 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”.

B 1 – 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.

The validity tests performed by the UPS are not exhaustive. You should not rely exclusively on these tests. Care should be taken when modifying the values of the parameters.

For all parameters except the LCD Contrast parameter the new value is saved and used after the ok button was pressed.

In the case of the LCD Contrast parameter the new value is used immediately in order to obtain a better visual feedback.

Modem enabled You can enable/disable with Y/N the remote control through modem calls

by using this parameter.

Init This parameter presents the modem initialization string. It can be 39 characters long.

When editing this parameter the UPS considers that a blank character

terminates the string.

If no blank character is found then all 39 characters are used.

Alarm This Y/N parameter controls the automatic events signaling through

modem.

If this parameter is set to Yes the UPS itself will call the remote location

when a new event occurs.

Delay This parameter controls the delay between the occurrence of a new event

and the modem dialing.

It is useful because since the events typically do not occur isolated but in

certain sequences, you can eliminate the need for multiple dial-outs for such a sequence of events.

The number of the event (255 = the most recent).

The standard code and the status word.

The date and time when the event occurred.

Code Alarms Meaning

Parameters are lost and have been replaced with default values. Call nearest Service Center for intervention. The master unit detected the slave unit missing on the communication bus even though switch Q1 is still closed. The u-switch mounted on the Rectifier Input Fuses indicates a blown fuse, and consequently shut down. Clearance of this condition allows you to restart the Rectifier. K4 not closed despite a closing command being issued. Signaled by auxiliary contact.

Rectifier cannot start. K4 not open despite an opening command being issued.

Signaled by auxiliary contact. Utility remains connected to Rectifier bridge. This function, when enabled on input programmable relays (password required), warns the user about the external Battery Fuses failure or MCB opening, signalled by NO free contact. Temperature sensor indicates an over temperature on the

Rectifier Bridge

Only alarm is given. The Rectifier, when in Off state, cannot start as long as this condition persists. The temperature sensor inside the input transformer winding indicates over temperature. Only the alarm is given. The Rectifier, when in Off state, cannot start as long as this condition persists.

Code Alarms Meaning

The Battery has been discharged and reached “stop operation” time-out (default 3 minutes), and the Inverter will

be shut down. It will restart automatically only when the Battery has recharged enough for a minimum runtime.

Dangerous high DC Voltage caused inverter shutdown. Inverter restarts automatically after Battery returns to floating voltage.

A leakage current to earth has been detected on the DC circuit.

During battery test the voltage falls under the critical level (depending setting parameters). Battery test is stopped.

Rectifier and Inverter are OFF. The DC power supply is discharging the Battery. Rectifier must be restarted or Battery must be disconnected in order to avoid damage. Rectifier Voltage hasn’t reached the set value (probably fault on regulation loop). LED Rectifier on control panel is blinking.

Inverter Output Fuses Inverter can be started manually after replacement of the

fuses. K7 not closed despite a closing command being issued. Signaled by auxiliary contact.

Load will be supplied by Utility. K7 not open despite an opening command being issued.

Signaled by auxiliary contact. Load will be supplied by Utility. The temperature sensor of the Inverter Transformer indicates over temperature. Elapsed “stop operation” time, Inverter shutdown. With Utility OK, Load is transferred on Utility. Blown input DC fuse(s) F1 of the Inverter. Inverter cannot be started as long as present. An abnormal condition has been detected on one or more power modules of the Inverter (temperature or over current). Inverter shutdown and cannot be started as long as the alarm is present.

Inverter Output Voltage is out of the tolerances (± 10%).

Inverter is switched OFF. Detection of Inverter Bridge (Is) current limit causing the Inverter OFF and automatic re-start.

After 3 times the Inverter switches-Off, and it can be restarted manually. The “Slave” oscillator is not in synchronized with the Master; thus causing the shutdown of it’s Inverter. If after a restart the condition remains, the LED inside the Inverter symbol on the panel will not light up, indicating that this Inverter cannot supply the Load anymore.

8.1.3 Programmable input free contacts

Some programmable UPS functions (indicated in Section 4.1), can be activated by closing an external contact, if connected, on:

X1 / 10, 21 or J2 / 10, 23 User Input 1 (default = Not used) (RL1) X1 / 11, 22 or J2 / 11, 24 User Input 2 (default = Emergency GEN ON) (RL2)

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.

8.1.5 AUX 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 X1/10-21 or J2/10-23, making the UPS operate as if the internal switch Q2 has closed.

This function can be activated by changing a dedicated parameter (password required).

When this NO (Normally Open) contact closes, the output Inverter Contactor K7 it is automatically opened and the Load transfer back to Inverter will be inhibited.

In a parallel system, the input on customer interface of each unit must be connected to a separate AUX contact of the External Maintenance Bypass Switch.

10 MAINTENANCE

10.1 MAINTENANCE

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 @ 1-800-637-1738

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 set-up parameters. The start up technician has access to this code and can program this feature during start up.

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.

10.1.5 Long shut-down periods of the UPS-system

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.

10.1.6 UPS room conditions and temperature

The UPS room and the Battery Room have to be maintained clean and free from dust.

A high temperature of the UPS room and of the Battery Room affect the lifetime of several components inside the equipment.

The Battery is very sensitive to room temperatures above 77°F (25°C).

10.1.7 Long shut-down periods of the UPS-system

Cleaning, a visual inspection and a mechanical inspection of the UPS modules.

Replacement of defective parts or the preventive replacement of parts with a defined lifetime

“Updating” of the equipment (technical improvements subsequent to the delivery).
