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.
Thedelayondeenergisationsafetycontactsmayonlybeuseduptomax.PLd(Cat.3).
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withdelayondeenergisation,anditis
usedtoexpandasafetycircuit.Thecontactexpansionmoduleisdrivenbyabaseunit(e.
g.emergencystoprelay).
}Functionalprocedureafterclosingthesafetycontactsofthebaseunit:
– Thesupplyvoltageispresentattheinput(A1)ofthecontactexpansionmodule.
– Closethesafetycontacts1718,2728,3738and4748.
– TheLEDs"CH.1"and"CH.2"arelit.
}Functionalprocedureafteropeningthesafetycontactsofthebaseunit:
– Thereisnotsupplyvoltageatinput(A1)ofthecontactexpansionmodule.
– Safetycontacts1718,2728,3738and4748openafterthedelaytime.
– 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).

Pleasenote:
}Informationgiveninthe"Technicaldetails[ 9]"mustbefollowed.
}Outputs1718,2728,3738and4748aredelayondeenergisationsafetycontacts.
}Topreventcontactwelding,afuseshouldbeconnectedbeforetheoutputcontacts(see

Byclosingorinterruptingtheinputcircuityoucancheckwhethertheunitswitchesonoroff
correctly.
Forsafetyreasons,theunitcannotbestartedifthefollowingfaultsarepresent:
}Contactmalfunction:Asthecontactblockisconnectedtoabaseunit,
reactivationwillnotbepossibleifthecontactshaveweldedaftertheinputcircuithas
