8.3.7 Possibilities
If one or more units have to be taken out of the power management system, the following possibilities exist
depending on the situation.
8.3.8 Auxiliary supply OFF
The auxiliary supply must be removed from the AGC. This means that a CANbus alarm occurs on the other
AGCs. These alarms appear in a 2 DG plant where ID 2 is powered down:
Alarms Functioning unit (ID 1)
System alarm Failed CAN tx line
System alarm CAN ID 2P/S MISSING (P = Primary CAN, S = Secondary CAN)
Menu 7533 Miss. all units
Menu 7535 Any DG missing
The alarms will be present at all times during the failure. A reconfiguration of the power plant is required to
remove the alarms.
