Output
TheICM492continuouslymonitorsincominglinevoltage
forfaultsanddisplaysRMSvoltageonthedigital
display.Whenlinevoltageisappropriate,ICM492closes
theCOMandN.O.relaycontacts.Whenincomingline
voltageisoutsideofuserselectedparameters,ICM492
willclosetheCOMandN.C.relaycontactsandindicate
afaultconditionbyashingFAULTondisplay.Theunit
recordsthelastvefaults,storingthehighestandlowest
voltagereadingsthatcausedthefault.TheUP,DOWN
andSELECTbuttonsarepressedsimultaneouslyto
clearthefaultsfrommemory.TheSELECTmenuhas
thefollowinguseradjustablesettings:voltagesetpoint,
timedelay,overvoltagepercentage,undervoltage
percentage,controlmode,andresponsetime.Time
delaypreventsshortcyclingwhenfaultnolongeris
presentandrapidpowerinterruptions.Theresponse
timeonthefaultconditioncanbeadjustedtohelp
reducenuisancetripsfromtransientfaults.When
ControlModesettingisselectedONthenICM492will
closeCOMandN.O.relaycontactsonlywhencontrol
voltageispresentatControlVoltageterminalsandthe
