MGE Galaxy 5000

3.10Operation of the Relay Communication Card (Dry Contacts)

All systems are equipped with this remote transmissions card (also known as SECI). A complete specification exists for the card used in MGE Galaxy 5000.

This card is used for the transmission of information between the system and the environment.

Two inputs and six outputs are available for the user (see the table below for the default programming).

3.10.1Standard Mode

It is compatible with all MGE systems that are I2 C compatible.

All the SA1 microswitches must be set to OFF (if two SECI cards are installed in the unit, the second card must be identified differently. On the second card, microswitch 1 on SA1 must be set to ON).

In this mode, the relays switch when the UPS changes status. The information listed below is transmitted if the parameters were enabled in UPS Tuner.

Inputs

Factory configuration

Other possible signals for each contact

 

 

 

1 A

UPS ON

- Temperature fault in room

 

 

- Transfer to bypass AC input disabled

 

 

- Transfer to bypass AC input disabled if it is out of tolerances

1.B

UPS OFF

 

 

- UPS not synchronized with the bypass AC input

 

 

 

Outputs

Factory configuration

Other possible signals for each contact

 

 

 

1.1

General alarm

- Overload

 

 

- PFC fault

 

 

- Inverter fault

1.2

Battery fault

- Charger fault

 

 

 

 

- Automatic-bypass fault

1.3

Load on UPS

- Bypass AC source out of tolerances

 

 

- Battery-temperature fault

 

 

- Ventilation fault

1.4

Load on automatic bypass

- Emergency power OFF activated

 

 

- Battery circuit breaker(s) open

 

 

- Phase inversion on normal or bypass AC input

1.5

Load on battery power

- Fuses blown

 

 

 

 

- Transfer to AC bypass disabled

1.6

Low battery warning

- Operation in ECO mode

 

 

- Load on maintenance bypass

 

 

 

The indications 1.X become 2.X for a second identical card in the UPS. Contacts are of the NO (normally open) type.

(1) The general alarm can be tested by opening the battery circuit breaker.

3.10.2Programmable Mode

This operating mode is specific to the MGE Galaxy 5000. The description in this document concerns only the MGE Galaxy 5000.

Microswitch 3 on SA1 must be set to ON (if two SECI cards are installed in the unit, the second card must be identified differently. On the second card, microswitch 1 on SA1 must be set to ON).

In this mode, it is possible to assign predefined operating status conditions (see the complete list) to the various SECI output relays and predefined UPS commands to the SELV inputs.

Assignments are made using the MGE Galaxy 5000 user-machine interface.
