ESM1-A AC Power Supply
ESM1-B DC Power Supply
1. INTRODUCTION
TherearetwoESM1variants,identicalotherthanpowersupplyneeds
 ESM1‐AACPowerRequired(85‐264VoltsAC,50‐60Hz)
 ESM1‐BDCPowerrequired(9.6‐36Volts)
Thisdocumentprovidesbasicinformationontheinstallationandconnectionof
theEarthSenseESM1InsulationMonitortoanITsystem.Complete
informationonsetupandspecificationisavailablefrom
www.mrd.com.au/dl/esm1‐UM.pdf
TheESM1featuresadaylightreadableLCD,andallfunctionscanbeaccessed
andcontrolledusingthetwobuttoninterface.Thecurrentbuttonfunctionis
identifiedusingon‐screenlabels,andthemenusystemissimpletooperate
andprovidesguidanceandfeedback.Dependingonexperienceand
knowledge,itispossibletoinstalltheESM1withoutconsultingthemanual.
2. PRODUCTDESCRIPTION
TheESM1monitorstheInsulationResistance(IR)ofanattachedcircuitand
alertssystemoperatorsiftheIRfallsbelowauser‐selectedtripvalueforlonger
thanapre‐setperiod.Alertdevicesare:
 On‐screendisplayandLEDcolour/flash
 RelayactivateddevicesandExternalcommunicationusingRS485.
TherearetwoUserselectabletripvalues,RAN1andRAN2,referredtoasWarning
andAlarm.Intheeventofanalert,untilReset,thedevicewill:
 ContinuetomonitoranddisplaythecurrentIRvalue
 DisplaythehighestrecordedalertState(WarningorAlarm)
 DisplaythelowestIRvaluerecorded
 CountandDisplaythenumberofhourssincealertstarted
 ChangeLEDcolourandActivateRelay(s)(Ifthealertstate
continuesbeyondtheTripDelayperiod)
WarningandAlarmhavethefollowingsettableparameters:
 Trip(Response)Value(k)andTripDelay(seconds)
 RelayActivated(1or2)andActivatedState(NormallyOpenor
Closed)
Resetaredonemanually(onthedevice)orremotely(usingRS485ora
connectedresetswitch),orthedevicecanbeconfiguredtoAuto‐ResetiftheIR
increasesabovetheWarningvalue.
