Page 6: Planning
Safety Manual SIL KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Planning Planning System Structure 2.1.1 Low Demand Mode of Operation If there are two 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 7: Assumptions
Safety Manual SIL KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Planning Assumptions The following assumptions have been made during the FMEDA analysis: Only one input and one output are part of the considered safety function (only 2-channel version). The device shall claim less than 10 % of the total failure budget for a SIL2 ... -
Page 8: Safety Function And Safe State
Safety Manual SIL KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Planning Safety Function and Safe State The safe state of each channel is "output de-energized", independent of the mode of operation. The safety function has two modes of operation: normal operation (output follows input) inverted operation (output inverts input) ... -

Page 10: Safety Recommendation
Safety Manual SIL KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Safety Recommendation Safety Recommendation Interfaces The device has the following interfaces. For corresponding terminals see data sheet. Safety relevant interfaces: KCD2-SR-(Ex)1.LB(.SP), HiC2821: input I, output I, output II KCD2-SR-(Ex)2(.SP), HiC2822: input I, input II, output I, output II Non-safety relevant interfaces: output ERR ... - Page 11 Safety Manual SIL KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Safety Recommendation Our experience has shown that the useful life time of a Pepperl+Fuchs product can be higher if there are no components with reduced life time in the safety path (like electrolytic capacitors, relays, flash memory, opto coupler) which can produce dangerous undetected failures and if the ambient temperature is significantly below 60 °C.

Page 12: Installation And Commissioning
Safety Manual SIL KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Safety Recommendation Installation and Commissioning During installation all aspects regarding the SIL level of the loop must be considered. The safety function must be tested to ensure the expected outputs are given. When replacing a device, the loop must be shut down. In all cases, devices must be replaced by the same type. -
Page 13: Proof Test
Safety Manual SIL KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Proof Test Proof Test Proof Test Procedure According to IEC 61508-2 a recurring proof test shall be undertaken to reveal potential dangerous fails that are otherwise not detected by diagnostic test. The functionality of the subsystem must be verified at periodic intervals depending on the applied PFD in accordance with the data provided in this manual. - Page 14 Safety Manual SIL KCD2-SR-(Ex)*(.LB)(.SP), HiC282* Proof Test Multimeter KCD2-SR-Ex1.LB (mA) 240 R / 2.5 W 24 V DC Multimeter (mA) 240 R / 2.5 W 24 V DC Multimeter (mA) Multimeter (mA) 24 V DC Zone 0, 1, 2 Zone 2 Power I supply Supply...
