3.10 Operation of the Relay Communication Card (Dry Contacts)
All systems are equipped with this remote transmissions card (also known as SECI).
Acomplete 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).
3.10.1 Standard Mode
It is compatible with all MGE systems that are I
2C 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.
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.
3.10.2 Programmable 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.
