}Useofaproductoutsidetheareasdescribedintheproductdocumentation
}Anyusethatisnotinaccordancewiththedocumentedtechnicaldetails.
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.

Therelaymeetsthefollowingsafetyrequirements:
}Thecircuitisredundantwithbuiltinselfmonitoring.
}Thesafetyfunctionremainseffectiveinthecaseofacomponentfailure.
}Thecorrectopeningandclosingofthesafetyfunctionrelaysistestedautomaticallyin

Functiondescription
Whenthesupplyvoltageissupplied,the"POWER"LEDilluminates.Theunitisreadyfor
operationwhenthestartcircuitisclosedorwhenastartcontactisopenedandclosed
againinthestartcircuit.
}Highsignalatinputcircuit(e.g.lightguardnorinterrupted):Thesafetycontactsare
closedandthesemiconductoroutputtransmits.
}Lowsignalattheinputcircuit(e.g.lightguardisinterrupted):Thesafetycontactsare
openandthesemiconductoroutputisdeenergised.

}SemiconductoroutputY32shouldnotbeusedforsafetycircuits!
}Topreventcontactwelding,afuseshouldbeconnectedbeforetheoutputcontacts(see
Technicaldetails).
}Usecopperwirethatcanwithstand60/75°C.
}Donotconnectcapacitiveload.
