The related safety function is defined as the outputs are de-energized safe state , if there is a line fault detected. LB 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. Observe the information in the manual. Observe the requirements for the safety loop. Connect the device only to devices that are suitable for this safety application.
