Mode of Operation
At power up, the ICM400 evaluates the incoming power for
proper phase sequence, amplitude, and symmetry (voltage
unbalance). If the three phase input at the line side connections
is within user set parameters, the internal relay is energized and
the load energize LED is turned on. Continuity will be across
terminals 4 and 6.
If connections are made to the load side terminals, the ICM400
will transfer monitoring over to the load side only. When a critical
fault condition (phase loss or phase reversal) is present, the relay
will immediately de-energize and the load energize LED will turn
off. Continuity will be across terminals 4 and 5.
If a non critical fault condition (unbalance, high or low voltage)
is present, the ICM400 will ignore it for the interrogation delay
time. If it is still present following the interrogation delay time,
the relay will de-energize and the load energized LED will turn
off. Continuity will be across terminals 4 and 5. The relay will
not energize if any fault conditions exist. The integral adjustable
delay on break timer will prevent short-cycling.
