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

(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1314,2324,3334and4344.

– 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.

– Openthesafetycontacts1314,2324,3334and4344.

– 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).

}Ifmorethan2unitsareinstallednexttoeachotherinthecontrolcabinet,leaveadis

tanceofatleast6mmbetweentheunits.

}Theoutputs1314,2324,3334and4344aresafetycontacts.

}Topreventcontactwelding,afuseshouldbeconnectedbeforetheoutputcontacts(see
