ICM Controls ICM455 Installation, Operation & Application Manual page 2

Parameter Description
Line Voltage Average phase to phase line voltage.
Delay on Amount of time between the load de-energizing and re-energizing.
Break
Delay on Fault Amount of time before the load de-energizes due to a non-critical fault.*
% Over/Under Maximum/Minimum phase to phase average voltage, respectively.
Voltage
% Phase Amount of allowable voltage unbalance.
Unbalance
Reset Mode AUTO or number of times the load can be re-energized after a load side fault before a manual reset is
necessary.
Note: When monitoring line side only, the reset mode will always be AUTO.
Control Mode When control mode is set to OFF, the load will energize if no 3-phase fault condition exists. With control mode
ON, the load will energize if no fault conditions exist and control voltage is present at terminals 3 and 4.
Set Date/Time Set date and time in order to store faults in real time. When first powered on, or after a long power outage, you
will be prompted to set the date and time when SETUP is pressed.
* 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 of under 2
seconds and it is not user adjustable.
** For best recommendations, consult manufacturer of equipment.
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
Line Over Average phase-phase voltage exceeds the maximum
Voltage percentage
Line Phase Not all three of the phases on the line side are present
Loss
Line Phase Lines 1, 2, or 3 are not in sequence (not 120° phase shifted)
Reversal
Line Phase A voltage unbalance between the three line phases exceeds
Unbalance the unbalanced set point
Line Under Average phase-phase voltage in below the minimum
Voltage percentage
Load Not all three of the phases on the load side are present
Phase
Loss
Load Loads 1, 2, or 3 are not in sequence (not 120° Phase
Phase Rev Shifted)
Load A voltage unbalance between the three load phases
Phase exceeds the unbalance set point
Unbalance
Brownout All three phases lost (0V)
* ONLY swap phases during initial setup, not after the ICM455 has been in operation without errors.

ONE-YEAR LIMITED WARRANTY
The Seller warrants its products against defects in material or workmanship for a period of one (1) year from the date of
manufacture. The liability of the Seller is limited, at its option, to repair, replace or issue a non-case credit for the purchase
prices of the goods which are provided to be defective. The warranty and remedies set forth herein do not apply to any
goods or parts thereof which have been subjected to misuse including any use or application in violation of the Seller's
instructions, neglect, tampering, improper storage, incorrect installation or servicing not performed by the Seller. In
order to permit the Seller to properly administer the warranty, the Buyer shall: 1) Notify the Seller promptly of any claim,
submitting date code information or any other pertinent data as requested by the Seller. 2) Permit the Seller to inspect and
test the product claimed to be defective. Items claimed to be defective and are determined by Seller to be non-defective
are subject to a $30.00 per hour inspection fee. This warranty constitutes the Seller's sole liability hereunder and is in lieu
of any other warranty expressed, implied or statutory. Unless otherwise stated in writing, Seller makes no warranty that
the goods depicted or described herein are fit for any particular purpose.

Parameters
Fault Conditions
Corrective Action
1. Check system for over-voltage cause.
2. Increase the percent over-voltage setting if necessary.
3. Increase fault line interrogation if necessary.
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 (ex: Line 1
2. Repair the missing phase.
1. Turn OFF power.
2. Swap any 2 phases on the line side of the IMC455 (example: swap Line 1 and Line 2).*
3. Re-apply power.
1. Press the READ button to observe the present line voltages. Check system for unbalance cause.
2. Increase fault interrogation time if necessary.
3. Increase the percent unbalance setting if necessary.
1. Check system for under-voltage cause.
2. Increase the percentage under-voltage setting if necessary.
3. Increase fault time interrogation if necessary.
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 damage, debris, or excess carbon.
1. Turn OFF all power.
2. Swap any 2 phases on the load side of the ICM455 only (example: swap load 1 and 2).*
3. Re-apply power.
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.
Check system supply voltage for cause of voltage loss
Troubleshooting
Corrective Action
N/A Use calibration method described in "Button Functions".
Confirm that the control input (terminals 3 and 4) is properly connected and configured.
Press FAULT once to observe the current fault; correct the condition of the first fault
that appears (see Fault Conditions above for a list of corrective actions.
Indicates there are faults saved in the memory, press FAULT rapidly to scroll through
saved faults; to clear the faults, press and hold FAULT for more than 5 seconds.
The control mode setting is off; press SETUP to get to the control mode. Press
set control mode on.
To exit setup mode, press either READ or FAULT.
Unit in lockout; maximum number of retires in manual reset mode has been reached. To
reset unit, press FAULT and hold for more than 5 seconds.
Fix load side fault. Press FAULT to observe condition; the delay on break period may
be too short; press SETUP to enter the delay on break mode; press
delay.
