Troubleshooting
At each service, please check all the functions described in the relevant section on commissioning.
Problem
Possible cause, tip
Error message in the display (Ennn)
See the section above on error messages.
The door reverses and the red LEDs M1/M2 start flashing.
Is the load guard correctly installed?
Has the correct supply voltage been set? Mechanical fault?
Does the door move easily when decoupled?
Are the red LEDs SE.C1, SE.C2, SE.O1 or SE.O2 on or
flashing?
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.
The door will not open or close.
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 door will not close but it will open.
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.
No automatic closing.
Suspect an interruption somewhere in the stop circuit.
Wicket door contact? Stop button? Check the setting for
restart after stopping.
