2 DESCRIPTION 2.1 SCB - SYNCHRONIZATION OF CRITICAL BUSES

Fig. 2.1-1 SCB – Synchronization of Critical Busses block diagram

The UPS configuration in Fig. 2.1-1 enhances security, reliability and safety of a system for the power supply to extremely critical loads. Basically it is composed of 4 major blocks, see Fig 2.1-1: • UPS Group A: this group can be minimum 1, maximum 6 units.

• UPS Group B: this group can be minimum 1, maximum 6 units.

• ISM – Intelligent Synchronization Module. ISM (Intelligent Synchronization Module) allows synchronizing of two independent groups of parallel UPS’s, each having a maximum of 6 UPS units of equal rating from 10 – 500 kVA.

• STS – Static Transfer Switch. A Static Transfer Switch can select between 2 sources (UPS groups). As standard the Static Transfer Switch will supply the load from the preferred source. In case the source would fail it will transfer the load to the second source. A condition is that both sources are synchronized continuously, also on battery operation.

Each group of UPS’s are independent and capable to supply the full load, eventually redundant. Each unit in the group is synchronized to its Master, which in return synchronizes to the utility voltage, if available.


Features & benefits:

• Redundant Power Supply providing highest reliability.

• Redundant Communication Bus tolerating an accidental cable cut.

• CRC Code (Cyclic Redundancy Check) for error free communication.

• High Precision Synchronization offering seem less transfer from one source to the other.

• Top and Bottom Cable access for easy installation.

• Compatible with GE SitePro (only series 6) and SG Series UPS and with GE’s unique RPA concept.

• Global Power Supply Voltage for worldwide usage (208, 400 or 480 VAC – 50 / 60 Hz).

• Synchronizes 2 groups of max. 6 UPS units (ranging from 10 - 500 kVA) each offering great flexibility.

• User Friendly Control Panel providing complete information on the spot. 2.1.1 STS - Static Transfer Switch

Fig. 2.1.1-1 STS - Static Transfer Switch block diagram

The STS is designed for the switching of two alternativepower sources without interruption of the supply toenergy receivers. The STS is connected to two sources of electrical powerwith terminal X01 for the Group A source and X02 forthe Group B source. Depending on current settings and system status, oneof the two sources (Group A or Group B) is connected tothe output terminal X03 (STS Output). K1, K2, K3, K4 and K5 are manually operated circuitbreakers. K1 and K2 are normally open, while K3, K4 and K5 arenormally closed. X01, X02 and X03 are terminals.

The operation is extremely simple and is structured on three important main menus related to the ISM operation, as follows: METERING An ISM must offer some metering information for the user to be able to examine

the operating status at any time.

ALARMS In case of abnormal functioning, the ISM must keep a history of what has happened as a series of events.

PARAMETERS The user must be able to program certain functions of the ISM (user parameters, accessible without password) to his needs.

6.2.1 Events (Alarms and Messages)

Each of the following listed events can be displayed on the LCD screen. Alarms and Messages are differently specified because the alarms are indicating an abnormal functioning of the ISM (which are additionally signalled with the LED alarm and acoustically with the buzzer), while the messages indicate the various states of operation of the ISM (stored in the events list, but not activating the LED alarm and the buzzer). When in alarms mode, the LCD screen displays a time ordered sequence of screens corresponding to the last 256 alarms and messages, each screen indicating:

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

7 OPERATION

WARNING !

Before connecting hazardous voltages, make sure that: • The cables for ISM supply and communication are correctly connected and in

accordance with existing standards; • The equipment frame has been correctly grounded to the earth; • All panels, which had been previously removed to allow ISM connection, have been

correctly reinstalled; • Make sure fuse holders “F1, F2, F3, F4” inside the ISM cabinet and “F5, F6, F7, F8” in

the distribution cabinet(s) are closed.

7.1 PROCEDURES FOR SCB - SYNCHRONIZATION OF CRITICAL BUSSES Procedure for SCB - Synchronization of Critical busses start-up As soon as one of the UPS’s, either from Group A or Group B supplies the load, the ISM system will automatically start-up.

NOTE ! As the ISM system starts-up, an Alarm is issued and the Buzzer starts sounding if the synchronization at the last shutdown was disabled (“SYNC OFF”).

To enable synchronization, press either the key “SYNC AUTO” for automatic choice of the synchronization source, or “SYNC MASTER A” / “SYNC MASTER B” to choose manually one of the two. Condition for the above is that at least one UPS of a group has it’s electronics supplied and at least one parallel group supplies the load, and consequently the ISM. To switch from automatic to manual synchronization, press one of the keys marked “SYNC MASTER A” or “SYNC MASTER B”, depending on which group is desired to be the Super Master. To change from manual synchronization to automatic, press the key “SYNC AUTO”. To disable synchronization press key “SYNC OFF”.

NOTE ! If a parallel system with an active synchronization command is shutdown (including electronics), the command for synchronization will be disabled and the “Alarm 4005 - Group failure on ISM system” is issued, together with an acoustical signal from the buzzer.

Procedure for SCB - Synchronization of Critical busses shutdown If no UPS of either Group A or B supplies the load, the ISM system is shutdown automatically.


8 MAINTENANCE An ISM system, like other electrical equipment, needs periodic preventive maintenance. A regular maintenance check of your installation guarantees higher reliability of your ISM. Preventive maintenance work on the ISM can be done only by trained Service Technicians. We therefore recommend you sign a Maintenance and Service contract with the local Service Centre organisation. The ISM follows the same service program and intervals as for UPS systems. Service check If this LED 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 Centre for preventive maintenance work. ISM room conditions and temperature The ISM room has to be maintained clean and free from dust. A high temperature of the ISM room affects the lifetime of several components inside the equipment. Component with limited lifetime We recommend the replacement of component such as lithium battery for the backup of data on the control boards of the units every 50’000 hours.


9 NOTES 9.1 NOTES FORM It is recommended to note in this section Notes, with dates and short descriptions, of all the operations performed on the ISM, such as: maintenance, components replacement, abnormal situations, etc. .
