Genset Start and Alarm
The Genset start and Alarm is an accessory module installed on TransferPacT Automatic and TransferPacT Active Automatic controller with following functions:
-
Genset output control with optional time delay function, 1 NC and 1 NO dry contacts are provided.
-
Alarm output, 1 NO dry contact is provided.
-
Green LED on the top of the accessory indicates the power status and proper connection of the accessory.
-
Communication with the main MCU on ATSE.
-
Only one Genset start (with capacitor) and alarm is allowed to be installed on one product.
Application Genset Start Output
When the utility source is lost, a dry contact will start the Genset irrespective with or without external 24 VDC. A time delay (T7) before Genset start can be set with or without external 24 V.
If the time delay (T7) is longer than 60 s, it is mandatory to have an external 24 VDC power supply.
When the utility source has recovered and ATSE has transferred back to utility, the Genset signal will remain until the end of the Genset cooldown timer.
Alarm
When there is an alarm, a dry contact will give the signal.
For TransferPacT Automatic, restart the controller (open and close the dielectric door) to shut down the alarm.
For TransferPacT Active Automatic, refer to Alarm and follow the procedures to acknowledge the alarm.
The alarm signal is irrelevant to Genset start or stop. It is relevant to transfer errors and phase rotations errors listed in Alarm Message .
