ICM450
THREE-PHASE VOLTAGE MONITOR
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.

Mode of Operation
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.
