Control Mode With control mode set to OFF, the load will energize if no 3- phase fault conditions exist; with control mode ON,
the load will energize if no fault conditions exist and control voltage is present at terminals 4 and 5 of the ICM450A
ON or OFF ON Based on wiring

* Non-critical faults are faults such as high/low voltage and phase unbalance. Critical faults, such as phase loss and phase reversal, have a fault interrogation and typical response time of
under 4 seconds and it is not user adjustable.

Press and release fault button to scroll through all saved faults.
Note: For initial setup, press and hold FAULT for 5 seconds to remove any previously stored faults.
Fault Problem Corrective Action
Back Phase Loss Not all three of the phases on the load side
are present
1. Re-energize the contactor.
2. If the fault reappears after the load energizes:
a. Turn all power OFF
b. Check all load side connections
c. Check the contacts of the contactor for debris or excess carbon.
Back Phase Rev Loads 1, 2, or 3 are not in sequence
(not 120º phase shifted)
1. Turn OFF all power.
2. Swap any 2 phases on the load side of the ICM450A and ICM450A PLUS+ only (example: swap load 1 and
load 2) *
3. Re-apply power.
Back Phase Unbalance A voltage unbalance between the three load
phases exceeds the unbalance setpoint
1. Press the READ button to observe the present load voltages. Check system for unbalance cause.
2. Increase the fault interrogation time if necessary.
3. Increase the percent unbalance setting if necessary.
Front Over Voltage Average phase-phase voltage exceeds the
maximum percentage
1. Check system for over-voltage cause.
2. Increase the percent over-voltage setting if necessary.
3. Increase the fault interrogation time if necessary.
Front Phase Loss Not all three of the phases on the line side
are present
1. Press and hold the READ button on the phase monitor or use an AC voltmeter to carefully measure all three
phase-phase line voltages (example: Line 1 Line 2, Line 2 Line 3, Line 3 Line 1).
2. Repair the missing phase.
Front Phase Reversal Lines 1, 2, or 3 are not in sequence
(not 120º phase shifted)
1. Turn OFF all power.
2. Swap any 2 phases on the line side of the ICM450A and ICM450A PLUS+ (example: swap Line 1 and Line
2)*
3. Re-apply power.
Front Phase Unbalance A voltage unbalance between the three line
phases exceeds the unbalance setpoint
1. Press the READ button to observe the present load voltages. Check system for unbalance cause.
2. Increase the fault interrogation time if necessary.
3. Increase the percent unbalance setting if necessary.
Front Under Voltage Average phase-phase voltage is below the
minimum percentage
1. Check system for under-voltage cause.
2. Increase the percent under-voltage setting if necessary.
3. Increase the fault interrogation time if necessary.
Fault Conditions
* Only swap phases during initial setup, not after the ICM450A and ICM450A PLUS+ has been in operation without errors.
