11.3.4 M‐Bus+pulseoutputs(typeno.:HC‐003‐21)
TheM‐BusmoduleispoweredthroughtheM‐Busnetworkandisthusindependentofthemeter’sinternalsupply.
Two‐way communication between M‐Bus and energy meter takes place via a digital isolator providing galvanic
separationbetweenM
‐Busandmeter.
Themodulesupportsbothprimary,secondaryandenhancedsecondaryaddressing.Themodulecancommunicateat
communicationspeedsof300,2400,9600or19200baudandautomaticallydetectsthespeedused.
TheoutputdatapackagecanbeconfiguredtoincludevariousregistercombinationsbymeansofthePC‐
programs
METERTOOLHCWandREADyManager.

ThemoduleisfittedwithtwosetsofscrewterminalsforconnectiontotheM‐Busnetwork.TheM‐Buscablecanthus
beloopedthroughthemetersothattheuseofjunctionboxescanbeavoided.Theconnectionisindependentof
polarity.The
M‐Buscablemustbecoppertwistedpair.Maxcablesizeis1.5mm

11.3.5 M‐Bus+ThermalDisconnect(typeno.HC‐003‐22 )
ThisM‐Busmodulehasanoutputforconnectionofa24VAC,normallyopenornormallyclosed,thermalactuator,
whichissuppliedbythemodule’sexternalpowerconnection.ThermalDisconnectenablesremotediscon nectofthe
flow,e.g.
inconnectionwithenergymanagementandmaintenanceorasaresultofleakagedet ection.TheThermal
DisconnectsystemisphysicallyplacedontheM‐Busmodule,buttheoutputiscontrolledbyMULTICAL®bymeansof
commandsthataresentviatheM‐Busnetwork.Themoduleispower‐supplied
bythe24VACor230VACpowersupply
inMULTICAL®.Itisnotpossibletobattery‐supplyMULTICAL®.
The Thermal Disconnect module requires an external 24 VAC power supply for operating the thermal actuator.
Transformertypeno.6699‐403cansupplybotha24VAC‐suppliedMULTICAL®andathermal
actuatorwithapower
consumptionofupto5W.
ForcontrollingThermalDisconnectremotely,theWindows®‐basedPCprogramUSBMeterReaderisused.
