Page 10: Planning
Functional Safety SJ2-SN, SJ3,5-S(1)N 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 11: Assumptions
SIL 3 Application Only use the device in SIL 3 applications in combination with a control unit for SIL 3 safety applications from Pepperl+Fuchs, i. e. switch amplifier KFD2-SH-Ex1. • The device claims less than 25 % of the total failure rate for a SIL 3 safety loop. -
Page 12: Safety Function And Safe State
Functional Safety SJ2-SN, SJ3,5-S(1)N Planning Safety Function and Safe State Safe State The safe state of the device is the high impedance state (low current). Applications with control units or safety functions where the safe state is the low impedance state (high current) were not evaluated. -
Page 13: Characteristic Safety Values
Planning To ensure the safety of the safety loop according to SIL 3, only use control units for SIL 3 safety applications from Pepperl+Fuchs, i. e. switch amplifier KFD2- SH-Ex1. Reaction Time The reaction time for all safety functions is < 1 ms. -
Page 14: Useful Lifetime
Functional Safety SJ2-SN, SJ3,5-S(1)N Planning Useful Lifetime Although a constant failure rate is assumed by the probabilistic estimation this only applies provided that the useful lifetime of components is not exceeded. Beyond this useful lifetime, the result of the probabilistic estimation is meaningless as the probability of failure significantly increases with time. -
Page 15: Mounting And Installation
Connect the device in safety applications up to SIL 3 to a control unit for SIL 3 safety applications. Pepperl+Fuchs offers control units for SIL 3 safety applications, i. e. switch amplifier KFD2-SH-Ex1. Observe the limitations, see chapter 3.2. Configuration... -
