WARNING
Ine
ffectiveness of the protective device due to selection of an unsuitable encoder
The target safety-related level may not be achieved in the event of non-compliance.
►
Select a suitable encoder.
►
Take suitable measures against the encoder’s systematic errors and common causes of error.
Choosing the right encoder is crucial to achieving the desired safety integrity level (SIL) and performance level (PL).
S
ystematic faults and common cause faults (CCF), in particular, need to be minimized in this case.
