MGE UPS Systems 6000 manual Maintainability, Communication

MGETM GalaxyTM 6000 : Specification guide

Parallel UPS, three-phase, 250 to 3000 kVA*

* Power rating for an N+1 redundant configuration

10.1.3 - Status indications with mimic panel

Indication of status conditions shall be distinct of the graphic display.

Three LEDs on the control panel indicate the following status conditions:

ωload protected;

ωminor fault;

ωmajor fault.

The mimic panel shall represent the UPS and indicate the status of the load supply using five two-colour (red and green) LEDs:

ωload supplied (LED at UPS output on mimic panel),

ωinverter on (inverter LED on mimic panel),

ωoperation on battery power (LED between battery and inverter on mimic panel),

ωbypass activated (bypass LED on mimic panel),

ωPFC rectifier on (rectifier LED on mimic panel).

A buzzer shall warn the user of faults, malfunctions or operation on battery power.

10.2 - Communication

10.2.1 - Standard communication

It shall be possible to remote the following controls, indications and measurements. To that end, the UPS shall have as standard equipment:

ωa programmable communication card for data input/output.

The card shall be equipped with eight dry contacts, six for input data and two for output data.

ωat least three communication ports for later addition, without interrupting operation, of communication cards implementing different protocols, e.g. SNMP, JBus/ModBus, RS232, USB.

10.2.2 - Communications options

The UPS shall be designed to enable the extension of communications, without system shutdown, to the following types of cards:

ωan SNMP communication card for connection to an Ethernet network, for connection to a computer-network management system;

ωan RS485 serial-link communication card capable of implementing the JBus/ModBus protocol for connection to a building management system (BMS);

ωan RS232 serial-link communication card for communication with a modem and a remote-maintenance system;

ωan USB communication card;

ωan XML-Web communication card for direct UPS connection to an intranet network, without connection to a server, capable of supplying information via a standard web browser.

The UPS shall be detectable by supervision software for large UPS systems.

Shutdown and administration software shall be available in addition to the communication cards.

11 - Maintainability

For optimum safety during servicing, a maintenance bypass shall be available to completely isolate the UPS.

11.1 - Local and remote diagnostics and monitoring - E. Services

ωThe UPS shall be equipped with a self-test system to check operation of the system as a whole each time it is started. To that end, the supply control/monitoring electronics shall offer:

ωauto-compensation of component drift;

ωacquisition of information vital for computer-aided diagnostics or monitoring (local or remote);

ωoverall readiness for remote supervision services provided by the manufacturer.
