ICM450
Programmable Three Phase Voltage
Monitor with 25-Fault Memory
Protects motors from premature failure
and burnouts
Specification
Input
• Line Voltage: Universal, 190-630 VAC
• Frequency: 50-60 Hz
• Load Side Monitoring: Optional
• Control Voltage: 18-240 VAC
• Frequency: 50-60 Hz
Output
• Type: Relay, SPDT
• Voltage Range: 240 VAC @ 10A maximum
• Frequency: 50-60 Hz
Control Operating Temperature
• Operating Temperature: -40ºF to +167ºF (-40ºC to +75ºC)
• Storage Temperature: -40ºF to +185ºF (-40ºC to +80ºC)
LCD Operating Temperature
• Operating Temperature: -4ºF to +167ºF (-20ºC to +75ºC)
Mechanical
• Mounting: Surface mount using (2) #8 screws
• Terminations: Screw terminals
• Weight: 12 ounces (341 grams)
Dimensions
• 6 1/2" L, 4 1/4" W, 1 3/8" H (16.5 cm. L, 10.8 cm. W, 3.5 cm. H)
Parameters
Phase Unbalance Protection
• Voltage Unbalance: 2-20% adjustable
Over/Under Voltage Protection
• 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 should this occur
Delay on Break Timer
• Control Voltage: 18-240 VAC
• Time Delay: 0 to 10 minutes adjustable
Fault Interrogation Delay
• Time Delay: 0 to 15 seconds adjustable
• Provides a delay between fault detection and system shutdown - helps to eliminate
nuisance trips or unnecessary shutdowns
Installation of the ICM450 shall be performed by trained technicians only. Adhere
to all local and national electric codes.
Disconnect all power to the system before making any connections.
Caution
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.

LOAD
• Terminals 1 and 3 are the control signal input terminals
• "Control Mode" is turned ON or OFF in setup
• With "Control Mode" set to "ON," there must be a voltage
present on terminals 1 and 3 for the relay output terminals
4 and 6 to close; this voltage can be supplied from a
thermostat, pressure switch, etc.
• When the voltage on these terminals is re-applied,
the unit will not re-energize until the delay on break
(0-10 minutes) time has elapsed
• Use of terminals 1 and 3 is optional; they will be ignored if
the "Control Mode" is set to "OFF"
• Terminals 4 and 6 are "dry," normally open contacts
• Terminals 4 and 6 are closed when power is within
specifications
• Terminals 4 and 6 open when there is a fault
condition
• Terminals 4 and 6 open when there is a loss of the
control signal with "Control Mode" set to "ON"
