Resetting/Replacing Tripped Fuses - DAAB EP104 Instruction Manual

DAAB AUTOMATIC CONTROL UNIT EP104
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 S.E1, S.E2 or S.E3 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.

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 on? They should be on. Have the
wrong 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.
FC/SL 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 push terminals. Switch on the
power again with the jackable terminals disconnected.
Check that the automatic control unit is in pulse mode. Is
the FC/SL LED on? Are any of the safety edge LEDs on? Is
SL1 or SL2 on? 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.
