For isolated/compensated systems in case of 2-phase-to-ground and 3-phase-to-ground faults, whenever a
ground fault and phase fault occur at a same time, SICAM FCM indicates phase fault as a priority event on
HMI/Modbus.

Fault-Reset Mechanism

4.1.3
The fault status of the device can be reset through anyone of the following mechanisms:
•
Auto reset as per user-defined time setting
•
Digital input (DC 24 V to DC 60 V)
•
User interface through keypad (Reset)
•
RS485/Modbus interface
The following logic diagram shows the fault-reset mechanism.
