recognized at the encoder input the diagnostic time is set to "0" and immediately starts to
operate again.
If an encoder-based safety function is activated and if the diagnostic time has extended
the diagnostic testing interval of 12 hours, then the "Encoder fail" changes immediately
into the safe status "Encoder Fail":

Diagnosis time of 12 h expired -> the safety function is requested once more
Even if during an actively encoder-based safety functions the diagnostic interval is
exceeded because there is no movement, the module changes into the safe status
"Encoder Fail".

Expiration diagnostic time during the encoder-based safety function -> Encoder fail
The "Encoder Fail" status can be exited by deactivating all of the safety functions of the
module and after acknowledging the error message in the controller a movement can be
generated at the encoder. With this movement the diagnostic time is set to "0" again and
the module is ready for use, again.
Then the encoder-based safety functions of the module can be activated, again:
