Protects against Over and Undervoltage, and Rapid Short Cycling caused byTransient Faults and Power InterruptionsThe ICM492 is specifically designed to monitor linevoltage and guard single phase equipment againstdamage caused by under and over line voltageconditions and rapid short cycling. Records last fivefaults.DESCRIPTION• Universal Line VoltageInput• Easy-view Backlit DigitalDisplay• RMS Voltage Monitoring• 5-fault memory storage• Adjustable Voltage SetPoint• Adjustable Over VoltageSet Point• Adjustable UnderVoltage Set PointFEATURES• Adjustable Anti-ShortCycle Time Delay• Adjustable Response onFault Time• Control Mode• 5-Fault Memory• Universal ControlVoltage Input• Heavy Duty SPDT RelayOutputThe ICM492 continuously monitors incoming line voltagefor faults and displays RMS voltage on the digitaldisplay. When line voltage is appropriate, ICM492 closesthe COM and N.O. relay contacts. When incoming linevoltage is outside of user selected parameters, ICM492will close the COM and N.C. relay contacts and indicatea fault condition by flashing FAULT on display. The unitrecords the last five faults, storing the highest and lowestvoltage readings that caused the fault. The UP, DOWNand SELECT buttons are pressed simultaneously toclear the faults from memory. The SELECT menu hasthe following user adjustable settings: voltage set point,time delay, over voltage percentage, under voltagepercentage, control mode, and response time. Timedelay prevents short cycling when fault no longer ispresent and rapid power interruptions. The responsetime on the fault condition can be adjusted to helpreduce nuisance trips from transient faults. WhenControl Mode setting is selected ON then ICM492 willclose COM and N.O. relay contacts only when controlvoltage is present at Control Voltage terminals and theline voltage is good. The relay contacts can be usedto direct drive the load as long as current rating is notexceeded.MODE OF OPERATION!!! WARNING !!!Electrical Shock Hazard• Verify power is disconnected by removing a fuseor opening a circuit breaker before making anyconnections.• This control should be installed by a trained technician.• Incorrect installation can cause personal injuries,property damage or death.• Follow all local & national codes while installing control.
