ICM Controls ICM401A Phase Monitor with Surge Protection

Upon wiring three phase voltage (180-600 VAC) to the ICM401A and connecting 24 VAC single-phase voltage to the Y & C terminals, the control will continuously monitor the three-phase line for phase loss and phase reversal. If all voltage conditions are within the specified range, a green light will illuminate on the ICM401A, and the Y-OUT terminal will be energized with 24 VAC. Upon a phase loss or a phase reversal, a red fault light will illuminate on the ICM401A indicating a fault is presently occurring and the Y-OUT terminal will be de-energized. Once the fault is no longer present and providing the 24 VAC control voltage is still applied at Y & C, the ICM401A will automatically re-energize the Y-OUT terminal.
