INFORMATION
Thisgivesadviceonapplicationsandprovidesinformationonspecialfea
tures.
Intendeduse
TheunitmeetstherequirementsofEN6094751,EN602041andVDE01131.Thecon
tactexpansionmoduleisusedtoincreasethenumberofinstantaneoussafetycontacts
availableonabaseunit.Baseunitsareallsafetyrelayswithfeedbackloopmonitoring.
ThecategorythatcanbeachievedinaccordancewithENISO138491dependsonthe
categoryofthebaseunit.Thecontactexpansionmodulemaynotexceedthis.
Foryoursafety
}Onlyinstallandcommissiontheunitifyouhavereadandunderstoodtheseoperating
instructionsandarefamiliarwiththeapplicableregulationsforhealthandsafetyatwork
andaccidentprevention.
EnsureVDEandlocalregulationsaremet,especiallythoserelatingtosafety.
}Anyguaranteeisrenderedinvalidifthehousingisopenedorunauthorisedmodifica
tionsarecarriedout.
}NoteforovervoltagecategoryIII:Ifvoltageshigherthanlowvoltage(>50VACor>120
VDC)arepresentontheunit,connectedcontrolelementsandsensorsmusthavea
ratedinsulationvoltageofatleast250V.

Safetyfeatures
Theunitmeetsthefollowingsafetyrequirements:
}Thecontactexpandermoduleexpandsanexistingcircuit.Astheoutputrelaysare
monitoredviathebaseunit'sfeedbackloop,thesafetyfunctionsontheexistingcircuit
aretransferredtothecontactexpandermodule.
}Thesafetyfunctionremainseffectiveinthecaseofacomponentfailure.

Functiondescription
Thecontactexpansionmoduleisanaddondevicewithoutdelayondeenergisation,andit
isusedtoexpandasafetycircuit.Thecontactexpansionmoduleisdrivenbyabaseunit

– Closethesafetycontacts1314,2324,3334,4344and5354.
– TheLEDs"CH.1"and"CH.2"arelit.
}Functionalprocedureafteroneorbothinputcircuitsareopen(safetycontactsofthe

– Openthesafetycontacts1314,2324,3334,4344and5354.
– TheLEDs"CH.1"and"CH.2"goout.

Installation
}TheunitshouldbeinstalledinacontrolcabinetwithaprotectiontypeofatleastIP54.
}UsethenotchontherearoftheunittoattachittoaDINrail.
}EnsuretheunitismountedsecurelyonaverticalDINrail(35mm)byusingafixingele
ment(e.g.retainingbracketoranendangle).
Wiring
Pleasenote:
}Informationgiveninthe"Technicaldetails[ 9]"mustbefollowed.
}Theoutputs1314,2324,3334,4344,5354aresafetycontacts.
}Topreventcontactwelding,afuseshouldbeconnectedbeforetheoutputcontacts(see
Technicaldetails).
