Functional Safety KCD0-SD3-Ex1.1*45 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.
Functional Safety KCD0-SD3-Ex1.1*45 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. • The safety-related device is considered to be of type A device with a hardware fault tolerance of 0.
Functional Safety KCD0-SD3-Ex1.1*45 Planning Safety Function and Safe State Safe State The safe state of the output is the de-energized state. The output current is less than 50 A. Safety Function When the input signal is active, the output is activated. The safe state is introduced when the input voltage is below 5 V DC.

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.
