Page 9: Planning
Functional Safety KFD2-SH-Ex1(.T)(.OP), KHA6-SH-Ex1 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
• The fault indication output which signals if the field circuits are broken or shorted is not considered in the FMEDA and the calculations. • For output I of the KFD2-SH-Ex1 and KHA6-SH-Ex1 devices, use the 3 redundant relay contacts to establish the necessary redundancy. - Page 11 Functional Safety KFD2-SH-Ex1(.T)(.OP), KHA6-SH-Ex1 Planning SIL 2 application If you use output I or output II of the device, you can reach SIL 2 according to IEC 61508. • The device shall claim less than 10 % of the total failure budget for a SIL 2 safety loop.

Page 12: Safety Function And Safe State
Functional Safety KFD2-SH-Ex1(.T)(.OP), KHA6-SH-Ex1 Planning Safety Function and Safe State Safe State The safe state of the outputs is the de-energized state. This state is reached when the input is in low state. Safety Function K***-SH-Ex1 The devices have two outputs that can be used for the safety function. Output I is a relay output with triplicated output relay, intended for use in applications up to SIL 3 or PL d. -

Page 16: Useful Life Time
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 17 Functional Safety KFD2-SH-Ex1(.T)(.OP), KHA6-SH-Ex1 Planning Maximum Switching Power of Output Contacts KFD2-SH-Ex1 I (A) Resistive load Resistive load Electrical life max. 10 switching cycles U (V) Figure 3.1 Maximum Switching Power of Output Contacts KHA6-SH-Ex1 I (A) Resistive load Resistive load Electrical life max.
