Environment information (cont.)
"LED" signalling box (optional)
A basic "LED" signalling box with four indication lights may be supplied as an option with the MGETM GalaxyTM 6000 system.
It supplies the following signals:
◗load on battery;
◗ low battery shutdown warning; ◗ inverter stop;
◗ general alarm.
It connects to the terminals presented on the preceding page and draws its power from the external 220V AC, 50Hz or 60Hz power supply not connected to a UPS.
Additional information "Media Contacts 15" (optional)
An additional board may be installed in all types of systems. Terminals XR5 to XR9 on the board may be used to receive additional information from the environment and supply more precise information on system status (see figures 18, 19, 20 and 22 for the position of the board).

Signal reception
The signals should be provided by volt- free contacts.
◗"desynchronization with Mains 2" signal inhibits the inverter from synchronizing its output frequency with that of Mains 2. The inverter supplies a stable frequency and the load may no longer be correctly transferred from the inverter to Mains 2. In the event of a malfunction or an overload, the transfer will take place with a 0.8 second interruption in the supply of power to the load;
◗"gradual rectifier/charger shutdown" signal makes the rectifier/ charger shut down progressively to avoid excessive step load variations in the event of a low output engine generator set replacing Mains 1;
◗"generator current limiting" signal makes the rectifier/charger current limit the power drawn when a low output engine generator set has replaced Mains 1. The additional power required for the inverter is supplied by the battery;
◗"battery charge current limiting" signal reduces the battery charge current (programmable parameter) in the event a low output engine generator set has replaced Mains 1;
◗"transfer to Mains 2 disabled" signal blocks transfer of the load from the inverter to Mains 2. In the event the inverter shuts down (overload, etc.), the load is no longer supplied (for modular UPSs, this information is disabled and transferred to an auxiliary output);
◗"transfer to Mains 2 with interruption disabled" signal blocks transfer of the load from the inverter to Mains 2 if it would result in an interruption in the supply of power to the load. Only
◗"auxiliary" signal can be used to provoke (depending on personalization):
◗a forced shutdown of the inverter (regardless of the status of Mains 2),
◗a protected inverter shutdown (transfer of the load to Mains 2 without interruption only if it is within tolerances),
◗modification of the inverter output frequency (50Hz or 60Hz);
◗"remote inverter on" signal can be used to remotely start the inverter;
◗"remote inverter off" signal can be used to remotely shut down the inverter.
Note:
In a system with a Static Switch Cubicle, the following signals must be directed to the Static Switch Cubicle:
◗desynchronization with Mains 2,
◗transfer to Mains 2 disabled,
◗transfer to Mains 2 with interruption disabled.
