Normal operation, not all monitored doors are closed.
Normal operation, all monitored doors are closed (after pressing the start button, for Manual start operating
mode)

Fault display
Internal component failure or actuator CES-A-BMB in the impermissible range or excessively high external interfer-
ence (EMC)
Operating fault
3x
Conguration error:
Teach-in operation must be performed again
Possible causes:
- State change during the teach-in operation
- The DIP switch setting and the conguration did not match during the teach-in operation
- DIP switch setting has been changed without teach-in operation
- The jumper (J1, J2) was tted with power supply switched on
- Closed feedback loop (Y1,Y2) present, although a feedback loop was not present during teach-in
- 24 V signal present at the start button input (S) although teach-in was performed with “Automatic start” operating
mode.
4 x
Fault in feedback loop
Possible causes:
- Malfunction of the monitored contactor
- Following removal from the operating distance, actuator is not outside the operating distance long enough; as a
result the feedback loop cannot be closed in this short time. Note the release time for the monitored contactor.
- Feedback loop was not closed on starting the evaluation unit
- Feedback loop was not closed on applying the operating voltage +UB.
