Alltheunitsusedwithinasafetyfunctionmustbeconsideredwhencalculatingthesafety
characteristicdata.
INFORMATION
Asafetyfunction'sSIL/PLvaluesarenotidenticaltotheSIL/PLvaluesof
theunitsthatareusedandmaybedifferent.Werecommendthatyouuse
thePAScalsoftwaretooltocalculatethesafetyfunction'sSIL/PLvalues.
Supplementarydata
CAUTION!
Itisessentialtoconsidertherelay'sservicelifegraphs.Therelayoutputs'
safetyrelatedcharacteristicdataisonlyvalidifthevaluesintheservicelife
graphsaremet.
ThePFHvaluedependsontheswitchingfrequencyandtheloadontherelayoutput.Ifthe
servicelifegraphsarenotaccessible,thestatedPFHvaluecanbeusedirrespectiveofthe
switchingfrequencyandtheload,asthePFHvaluealreadyconsiderstherelay'sB10d
valueaswellasthefailureratesoftheothercomponents.
Servicelifegraph
Theservicelifegraphsindicatethenumberofcyclesfromwhichfailuresduetowearmust
beexpected.Thewearismainlycausedbytheelectricalload;themechanicalloadisnegli
gible.
