Setup
4 Hz Initial setup after delivery without jumper connected to J1, J2 or J, 0V.
1 Hz Teach-in operation
Acknowledgement of completion of teach-in operation.
Normal operation
15 Hz
(10 s)
Self-test, duration approx. 10 seconds, is performed after applying the operating voltage U
B
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)
Function test Function test active (TST input = 24 V)
Fault display
Internal component failure or actuator CES-A-BMB in the inadmissible range or excessively high external
interference (EMC)
Operating fault
3 x
Configuration fault:
Teach-in operation must be performed again
Possible causes:
- State change during the teach-in operation
- The DIP switch setting and the configuration did not match during the teach-in operation
- DIP switch setting has been changed without teach-in operation
- The teach-in jumper (J1, J2 or J, 0V) was fitted 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.

Important:
If you do not find the displayed device status in the System status table, this indi-
cates an internal device fault. In this case, you should contact the manufacturer.
Note:
The read heads CES-A-LNN and CES-A-LSP have an integrated LED for the indication
of the door position. The LED illuminates with the safety guard closed.
