ICM455
Important Safety Information
HIGH VOLTAGE WARNING!
– Turn off power at the
main service panel before installing.
Programmable,
Three-Phase
Voltage Monitor
Phase Unbalance Protection
• Voltage Unbalance: 2-20%, adjustable
Over/Under Voltage
• Under Voltage: 2-25%, adjustable
• Over Voltage: 2-25%, adjustable
Phase Loss Protection
• Phase Loss Condition: Equals 25% of nominal for any given phase; system will
shut down and a fault will be recorded if this should occur.
Delay on Break Timer
• Control Voltage: 18-240 VAC
• Time Delay: 15 seconds to 10 minutes
Fault Interrogation Delay
• Time Delay: 0 – 15 seconds, adjustable
• Provides a delay between fault detection and system shutdown—helps to eliminate
nuisance trips and unnecessary shutdowns.

Button Functions
Press to return to home screen, which alternates between line voltage
and phase average.
Press arrow to scroll through and select parameter settings in Setup
Mode.
Voltage Read Calibration:
Hold both down to calibrate line voltage. Fault and setup LEDs will flash.
Usethe and buttonstoadjust.Press SETUP to exit calibration.
Press to enter Setup Mode and select user parameters. Setup LED
illuminates when in Setup Mode.
Press to read faults. Hold for 5 seconds to clear faults and reset memory.
Fault light will blink when fault has been added to memory.
Press and hold to reset system due to system error – this will not reset
the parameters.
To turn backlight on, press any button.
