Page 9: Planning
Functional Safety KF**-CRG2-(Ex)1.D Planning Planning System Structure 3.1.1 Low Demand Mode of Operation If there are two control loops, one for the standard operation and another one for the functional safety, then usually the demand rate for the safety loop is assumed to be less than once per year. -
Page 10: Assumptions
Functional Safety KF**-CRG2-(Ex)1.D Planning Assumptions The following assumptions have been made during the FMEDA: • Failure rate based on the Siemens standard SN29500. • Failure rates are constant, wear is not considered. • External power supply failure rates are not included. •... -
Page 11: Safety Function And Safe State
Functional Safety KF**-CRG2-(Ex)1.D Planning SIL 2 Application • The device shall claim less than 10 % of the total failure budget for a SIL 2 safety loop. • For a SIL 2 application operating in low demand mode the total PFD value of the SIF (Safety Instrumented Function) should be smaller than 10 , hence... -

Page 13: Useful Lifetime
As noted in DIN EN 61508-2:2011 note N3, appropriate measures taken by the manufacturer and plant operator can extend the useful lifetime. Our experience has shown that the useful lifetime of a Pepperl+Fuchs product can be higher if the ambient conditions support a long life time, for example if the ambient temperature is significantly below 60 °C. -
Page 14: Derating
Functional Safety KF**-CRG2-(Ex)1.D Planning Derating For the safety application, reduce the number of switching cycles or the maximum current. A derating to 2/3 of the maximum value is adequate. Maximum Switching Power of Output Contacts The useful lifetime is limited by the maximum switching cycles of the relays under load conditions. -
