ICM 3-Phase Voltage Monitor-Programmable ICM450

Stop Motor Burnouts!
3-Phase line voltage monitor with 25-fault memory, high temperature LCD display, easy setup & clear diagnostic display of system faults, 190-630 VAC operation... The ICM450 was specifically designed to protect motors and other 3-phase loads from premature failure and damage due to common voltage faults such as voltage unbalance, over/under voltage, phase loss, reversal, incorrect
sequencing and rapid short cycling.
• Reliable, high temperature LCD display simplifies system setup and diagnostics. Indicates condition of incoming line voltage, fault conditions, system setpoints and other user adjustments. Temp.: -20° to +75°C (-4° to +167°F)
• Simultaneous voltage display...an ICM exclusive!
View all 3 phases, no need to scroll through readouts.
• Fully adjustable variables...user may easily set and adjust variables when in SETUP mode:
• Line voltage: 190-600 VAC
• Voltage unbalance: 2-20%
• Delay on break period: 0-10 min.
• Fault interrogation: 0-15 sec.
• Over/under voltage: 2-25%
• Reset modes: AUTO or 0-10 Retries
• Control modes: ON or OFF
• Line voltage: universal- 190-630 VAC
• Frequency: 50/60 Hz
• Type: relay, SPDT
• Voltage range: Up to 240 VAC (Max: 10 amps)
• Frequency: 50/60 Hz Control Operating Temperature
• Operating temperature: -40° to +75°C, -40° to 167°F
• Storage temperature: -40° to +85°C, -40° to 185°F LCD Operating Temperature
Operating temperature: -20° to +75°C, -4° to 167°F Phase Unbalance Protection
Voltage unbalance: 2-20% adjustable
Over/under protection
• Under voltage: 2-25% adjustable
• Over voltage: 2-25% adjustable
Phase Loss Protection
Phase loss condition= <25% of nominal for any given phase. System
will shut down and a fault will be recorded should this condition occur.
Delay on Break Timer
• Control voltage: 18-240 VAC
• Time delay: 0-10 min. adjustable
Fault Interrogation Delay
• Time delay: 0-15 sec. adjustable
• Provides a delay between fault detection & system shut-down - eliminating nuisance trips/unnecessary Shutdowns.
• Mounting: surface mount using (2) #8 screws
• Termination: screw terminals
• Weight: 12 ounces (341 grams)
• Easy to install and configure...wiring diagram on unit, simple 7-step push-button setup, guide included.
• 25-Fault memory and storage...clearly displayed in LCD
• Ultra bright LED indicators...shows current mode:
Setup LED
Load energized LED
Control voltage LED
