ICM CONTROLS ICM493 Programmable Single-Phase Voltage Monitor Installation Guide
INSTALLATION
- Remove cover by extracting the screw from the bottom of the enclosure.
- Remove desired size knock-outs for conduit from the enclosure (1/2” or 3/4”).
- Mount the enclosure to the desired surface.
- Attach input and output conduit, apply strain relief.
- Tilt front panel diagonally and insert the panel into the enclosure, as shown in Figure 1.
- Lay the front panel horizontally in the enclosure and align the holes on the side, as shown in Figure 2.
- Using the two larger screws, included in the kit, and a screwdriver, attach the front panel to the enclosure.
- Wire L1 and L2 directly to the contactor input and output, as shown in Figure 3.
- Close the hinged plate and secure the upper right corner into the bracket with the small screw provided in kit.
- Once settings have been configured, attach cover and secure with screw.
CALIBRATION FEATURE
The ICM493 can be calibrated to match the reading from a true RMS meter.
- Measure input voltage from T1 to T2 using a true RMS meter.
- Hold
buttons simultaneously until line voltage starts to flash. - Adjust voltage using buttons to match measured voltage from step 1.
- Push
button to lock values into memory.

| Parameter | Description | Range | Default | Recommended |
| Line Voltage | The expected line voltage | 200-240 | 240 | Nameplate Voltage** |
| Over/Under Voltage | The allowed percentage over and under the set line voltage | 5% to 10% | 10% | 10% Over/Under |
| Anti-Short Delay | The amount of time delay between the end of a fault, and closing of the contactor | 0:30 to 10:00 | 0:30 | 4 minutes |
| Reset Mode Retries | The number of retries after a fault has occurred. Auto has unlimited retries. | 1 to 5, Auto | Auto | Auto |
| Allowed MOV Fail | The number of surge devices allowed to fail while maintaining operation. Setting to “5” will allow operation, even when surge protection has been exhausted. | 0 to 5 | 5 | Set to “5” for ensured operation. Set to “4” for max. operation while ensuring surge protection. |
