INSTRUCTION MANUAL DAAB AUTOMATIC CONTROL UNIT EP105

Revision 3
The display and LEDs do not switch on
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.
You will need to hold down the run button to operate.
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.
Does the door inexplicably close "by itself"? (without an
error message or alarm LEDs)
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.
• 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 drive unit.
• Reset or replace the fuse.
• Switch on the main switch to the automatic control unit.
• Check that none of the drive units start before receiving the control signal.
• Check that the drive units can be started and stopped from the control buttons.
• If the drive unit cannot be stopped, contact FAAC Nordic AB.
