3 Safety
3.1 Intendeduse
ThePWMrelayPNOZs50isdesignedforuseinsafetyrelatedapplications.
ThedevicemeetstherequirementsofENISO138491uptoPLeandENIEC62061upto
SILCL3.Forexample,itisdesignedforusewith
}Mechanicalholdingbrakes.
}Valves.
IntendeduseincludesmakingtheelectricalinstallationEMCcompliant.Theproductisde
signedforuseinanindustrialenvironment.Itisnotsuitableforuseinadomesticenviron
ment,asthiscanleadtointerference.
Thefollowingisdeemedimproperuseinparticular:
}Anycomponent,technicalorelectricalmodificationtotheproduct
}Useoftheproductoutsidetheareasdescribedinthismanual
}Useoftheproductoutsidethetechnicaldetails(seechapterentitled“TechnicalDe
tails”)
Pleasenotethefollowingsafetyguidelines:
Hazardanalysis
}Themachinemanufacturermustproduceahazardanalysisforthemachine.Hemust
takeappropriatemeasurestoensurethatunexpectedmovementsdonotleadtohaz
ardoussituationsforeitherpeopleorequipment.
Demandsonthesafetycontrolsystem
}ThePNOZs50mayonlybeoperatedinconjunctionwithahigherlevelsafetycontrol
system.
}Theoutputsonthesafetycontrolsystemusedtoactivatefastshutdownmustbetested
todetectshortsacrosscontactsandearthfaults.
}ThefaultsignaloutputO3mustbeevaluatedtogetherwithstatusoutputsO4(ifO1+/
O1isused)andO5(ifO2+/O2isused),ifthisisdemandedbytheplant/machine's
safetyrequirements.Processingofthesesignalsisusedtocheckthefeasibilityofthe
signalstates.Evaluationofthesesignalsmustbesuitabletoachieveasafecondition
fortheapplication.
Demandsontheconnected,inductiveload
}Theinductiveloadmustguaranteethedemandsonthesafetyfunctioninadeener
gisedstate.Forexample,inadeenergisedstateaconnectedsafebrakemustalways
beapplied,muststopahazardousmovementandmustpreventunintendedstartup.
Slowshutdownintheeventofafault
}Whendesigningasafeapplication,youshouldconsiderthataslowshutdowninstead
ofafastshutdownmaybeeffectiveintheeventofafault.Aconnectedbrakemayhave
alongerstoppingdistance.
Slowshutdown
}Thepowercircuit'sslowshutdownisnotsafetyrelated.Itmayonlybeusedwhenper
mittedbythehazardanalysis.
