manual RESET: A High pulse at I5 transmits the enable of the
comparator to the outputs. A High pulse at I6 revokes this
enable.
Behaviour of the device in the case of an error
The detection of random or systematic system errors in the
system or its control results in deactivation. In doing so, all
safety-oriented output circuits are switched off and the ERR
LED of the module lights or flashes. Error codes are also
output via the signal output X1 and the LEDs of the inputs.

In operating mode B-2, the specified safety level can only be adhered to if the sensor lines are individually sheathed and laid so
that they are protected.

Three error categories are distinguished:
 ERR lights:
 ERR flashes:
 ERR off:
Detailed information can be found in the manual.
The deactivation can be revoked if necessary by the user by
elimination of an error (e.g. in the control) and by switching off
the operating voltage and then switching it on again.
