27 Frequently asked questions
10. Opener works only in one direction:
• Door springs may be defective or the door is stiff in one direction.
• If the door is fine, re-programme operating power and stretch of way of
the opener.
11. The chain rattles on the rail:
• Adjust the chain tension. The cause is usually a very tight chain. The
spring on the clamping device of the rail must not be compressed
completely.
• The door runs unevenly and makes the drive vibrate. Improve door run.
12. Opener will not start due to power failure:
• Disconnect from the opener by pulling on the handle on the carriage
(manual release). The door can now be manually opened and closed.
If the opener is re-activated, the carriage also gets re-connected.
• If installed, the carriage is detached from the drive in case of power
failure by an external emergency release from outside the garage.
13. Door reverses after the force was programmed:
• See if the rail bends. The opener requires a lot of power to move the
door. Repair or install door correctly.
• Door is very heavy or in poor condition. Call a specialist.
14. Rail bends on the opener:
• Door is heavy, very heavy, stiff or in poor condition. Call a specialist.
• A swing of the rail while moving is a sign of an unevenly functioning
door with constantly changing power requirements. Call specialist,
possibly lubricate door. An additional suspension on the rail can be a
remedy.
15. The opener „runs“ (audible turning of motor) but the carriage
does not move:
• The carriage is released from the opener.
• In a new installation: During the assembly of motor and rail, the pre-as-
sembled adapter sleeve between the motor shaft and the rail was not
installed. This sleeve is pre-assembled at factory, but can be removed.
Standing behind the opener it can be observed whether the gearwheel
turns in the rail or just the motor.
• In a new installation: The chain has come off from the gearwheel in the
rail. Standing behind the opener, you can see the gearwheel.
• After years of use: Is the release defective or continuously disen-
gaged?
• After years of use: The sleeve between rail and motor or the motor
control gear is defective.
16. The door releases by itself from the carriage and stops:
• An external release that has been installed during a power failure
should be checked whether it stretches and releases during the open-
ing of the door. Watch the mechanism and reset if necessary.
• The handle of the release mechanism should not get caught in other
items.
17. The running path cannot be programmed, is de-programmed
or is changing slowly:
• The programmed running path is too short. Programme a longer path
for testing purposes.
• A small plastic knob is factory-mounted on the chain that is running in
the rail. During the travel of the opener this little button must press the
small switch located on the drive head. If the path is too short or the
button was torn down by incorrect installation, it has to be fixed again.
If the small switch is not pressed, the programming of the opener is not
possible.
• A mechanical fault at the door due to deected joints or the chain
tension on the drive is too loose.
18. Description of LEDs
LED1
• Flashes briey: A radio signal is received. Once the remote control is
programmed it opens and closes the opener.
• Is constantly on for approx. 10 seconds: An additional remote can be
programmed or all remotes will be deleted.
LED2
• Is constantly on: as long as the opener runs.
• Flashes: opener is in programming mode, „OPEN” position has already
been programmed and opener is ready for position „CLOSED“.
LED3
• Flashes: opener is in programming mode and ready for „OPEN“
position.
1. Door opener doesn’t work with remote control:
• Is the opener connected to the power supply? If a lamp connected
to the power socket does not turn on, check fuse or circuit breaker.
(Some sockets are enabled via a wall switch).
• Are all door locks disabled? See safety instructions!
• Does the control LED on the transmitter light up when the button is
pressed? If not, either the battery is empty, or the transmitter is defecti-
ve or too far removed from the opener.
• Try operating with a new battery.
• If you have two or more transmitters, of which only one works, check
programming of the receiver.
• Is there snow / ice under the door? If yes, the door may be frozen onto
the ground. Remove all obstacles.
• Perhaps the door spring is defective. This must be replaced by a
specialist.
2. Transmission range of the device is too low:
• Is a battery inserted? Put a new battery.
• Try radio control in the car at another location.
• The transmission range diminishes for metal doors, aluminium or metal
panels.
3. Door reverses for no apparent reason:
• Is the door hindered by anything? Pull manual release and operate
door by hand. In case of unbalanced or stuck gate, please contact the
service department.
• Re-programme operating power and stretch of way of the opener.
• Clear ice or snow in the closing area of the door.
• If the door reverses upon reaching the door position ‘Closed’, the limit
switch must be set for this door position.
After completing every setting, the automatic safety reverse must
be checked again:
• An occasional resetting of the end positions is not unusual.
In particular, the weathering can shift the doorway.
4. The garage door opens and closes by itself:
• Delete all transmitters and then re-programme them. See „Program-
ming of other handheld transmitters“.
• Is the remote control button jammed in position „ON“?
• Use only original remote controls! The use of third-party products leads
to disturbances.
• The remote control button was pressed accidentally (pocket).
• Cable of the wall switch is damaged (remove for testing purposes).
• An accessory connected to the opener causes the drive (remove for
testing purposes).
5. Door does not close completely:
• Re-programme stretch of way of the opener. Check for alterations in
the mechanical components, e.g. door arms and fittings.
After each new setting of the door position ‘Closed’, the automa-
tic safety reverse should be checked for function.
6. The door opens, but does not close:
• If installed, the light barrier should be checked. If the LED at the light
barrier blinks, the alignment should be checked.
• Check transmitter or wall switch for function.
7. Operator light doesn’t turn on:
• Open or close door. The light remains switched on for 2.5 minutes.
• Disconnect opener from the mains and connect again. The light comes
on for a few seconds.
• No power.
8. Operator light doesn’t turn off:
• Disconnect power from the mains supply for a short time and try again.
• The 2.5 minutes are not yet over.
9. Motor hums and runs very briefly, but does not function:
• Garage door springs are defective. Close the door and disconnect from
the opener by pulling on the handle of the carriage (manual release).
Open and close door manually. If the door is properly balanced, it is
held at each point of the doorway by the door springs alone. If this is
not the case, contact your service centre.
• If this problem appears during the first use, the door may be locked.
Deactivate door lock.
• Release opener from the door and try without door. If the door is fine,
re-programme operating force and stretch of way.
