At power up, the ICM450 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 load energize LED is

turned on and the internal relay is energized. Continuity will be across terminals 4 and 6. If connections are made to the

load side terminals, the ICM450 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, the load-

energized LED will turn off, the fault LED will flash, and the fault is written to memory. Continuity will be across terminals

4 and 5.

If a non-critical fault condition (unbalance, high or low voltage) is present, the ICM450 will ignore it during the interro-

gation delay time. If it is still present following the interrogation delay time, the relay will de-energize, the load-energized

LED will turn off, the fault LED will flash, and the fault is written to memory. Continuity will be across terminals 4 and 5.

The ICM450 will store the last 25 faults in memory. The relay will not energize if any fault conditions exist. The integral

adjustable delay on break timer will prevent short cycling.

Stop Motor Burnouts!

Programmable 3-phase line voltage monitor

with 25-fault memory, high temperature LCD

display, easy setup & clear, diagnostic readout

of system faults, 190 to 630 VAC operation...

The ICM450 was specifically designed to protect motors and

other 3-phase loads from premature failure and damage due

to common voltage faults such as voltage unbalance, over/

under voltage, phase loss, reversal, incorrect sequencing and

rapid short cycling.
