Troubleshooting
At each service, please check all the functions described in the relevant section on commissioning.
Problem
Error message in the display (Ennn)
The door reverses and the red LEDs M1/M2 start flashing.
Are the red LEDs SE.C1, SE.C2, SE.O1 or SE.O2 on or
flashing?
The door will not open or close.
The door will not close but it will open.
No automatic closing.
The display and LEDs do not switch on
You will need to hold down the run button to operate.
Does the door inexplicably close "by itself"? (without an
error message or alarm LEDs)
• Resetting/replacing tripped fuses
If the fuse protecting the power supply to the automatic control unit trips, FAAC Nordic AB recommends following these
steps to reset/replace it.
•
Switch off the main switch to the automatic control unit.
•
Decouple the motor winder.
•
Reset or replace the fuse.
•
Switch on the main switch to the automatic control unit.
•
Check that none of the motor winders start before receiving the control signal.
•
Check that the motor winders can be started and stopped from the control buttons.
•
If the motor winder cannot be stopped, contact FAAC Nordic AB.

INSTRUCTION MANUAL DAAB AUTOMATIC CONTROLL UNIT EP104 4.08
Possible cause, tip
See the section above on error messages.
Is the load guard correctly installed?
Has the correct supply voltage been set? Mechanical fault?
Does the door move easily when decoupled?
Check the channels for the safety edge value. Is the
impedance correct?
Adjust the safety edge switch if necessary? Are all the safety
edge units in use? Are any of the limit switch LEDs on?
The safety edge will not work unless the limit switches are
connected at the time the power is switched on.
Is the stop LED on? The safety edge will not work unless
the stop circuit is uninterrupted at the time the power is
switched on.
Are all the green LEDs that should be lit on? Have unused
stop inputs been jumpered? Are any of the LEDs INP1-
INP6 on? They should not usually be on (unless the system
is parked at certain times). The limit switch LEDs must light
up before the door can be operated. Example: L.O1 is on =
motor 1 can start. The limit switches are connected in series
with the stop circuit. Fault/interruption in the wicket door
contact or other contact in the stop circuit. Check that the
warning is configured. Check that the block is configured.
The PHOTO LED should be on. Are any safety edge
indications on? They should normally be off. Suspect an
incorrect connection to the safety edge. Alternatively, an
adjustment may be necessary. Check the channel for pulse
operation.
Suspect an interruption somewhere in the stop circuit.
Wicket door contact? Stop button? Check the setting for
restart after stopping.
Are all supply phases present? Possibly a short circuit to
earth in a low current connection. Switch off at the main
switch for 1 minute and remove all jackable terminals. Switch
on the power again with the jackable terminals disconnected.
Check that the automatic control unit is in pulse mode. Is the
PHOTO LED on? Are any of the safety edge LEDs on? Is
LOOP1 or LOOP2 lit? These should only be on if a vehicle
is over the loop.
Try to operate the door again, opening and closing. Also
check C020 for the most recent stop cause. Cross-check the
number with the channel reference to find out what stopped
the door.
