International Controls & Measure ICM450C 6-1/2 in. 3-Phase Voltage Monitor Installation manual
International Controls & Measure ICM450C is a programmable three-phase voltage monitor designed to protect motors from premature failure and burnouts. It monitors line voltage, load voltage (optional), phase unbalance, over/under voltage, phase loss, and phase reversal. The ICM450C features a 25-fault memory, adjustable fault interrogation delay, and a delay on break timer. It has a universal input voltage range of 190-630 VAC and a frequency range of 50-60 Hz. The output is a relay with a voltage range of 240 VAC at 10 A maximum.

Adhere to all local and national electric codes. Disconnect all power to the system before making any connections. Installation 1.Using (2) #8 screws, mount the ICM450 in a cool, dry, easily accessible location in the control panel. 2.Connect voltage as shown in Figure 1 (below). Leave existing line and load side connections intact on the contactor. 3.Load side monitoring is optional (unit may be used to monitor line side only). Wire the contactor and optional control voltage monitoring as in Figures 2 and 3 (below). Note: Load/line wire must be rated for 3-phase voltage rating, 20ga minimum. 4.Upon application of power, the ICM450 will be on line and will begin to monitor the system.

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. Fault Conditions 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 ICM450 only (example: swap load 1 and load 2) * 3. Re-apply power. Back Phase Unbal 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 Volt 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 Rev 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 ICM450 (example: swap load 1 and load 2)* 3. Re-apply power. Front Phase Unbal 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 Volt 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. * Only swap phases during initial setup, not after the ICM450 has been in operation without errors.
