ICM409
THREE-PHASE LINE MONITOR
All features and specications subject to change without notice.
The ICM409 is a low cost
three-phase voltage monitor
with fault indicator.
Protects Against...
• Low Voltage • Power Interruptions
• High Voltage • Phase Loss
• Unbalanced Voltage • Phase Reversal
Features
• Adjustable delay-on-make timer for staggered starting
• Adjustable delay-on-break for anti-short cycle protection
• Adjustable universal voltage from 190 VAC to 480 VAC
• Adjustable voltage unbalance from 2-8% of the line
voltage
Status LED Indicators
• GREEN LED = Load ON • RED LED
• Solid = Phase reversal
• 1 ash = DOM time
• 2 ashes = Low voltage
• 3 ashes = High voltage
• 4 ashes = Unbalanced
voltage

Mode of Operation
Designed in a small, easy-to-mount, surface mount or
DIN rail style case, the ICM409 continuously monitors the
incoming line voltage for errors. When the line voltage is
appropriate, the ICM409 closes a set of N.O. contacts and
lights a green LED. When the incoming voltage is outside
of the user’s set parameters, the N.O. contacts open
and the red light will ash a code for the particular fault
present. The control will also interrogate the line voltage
during the fault condition to avoid short cycling and
nuisance trips.
