8. Operator light doesn't turn off:
• Disconnect the 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.
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-assembled 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 dis-
engaged?
• 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
opening 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 deflected joints or the chain ten-
sion on the drive is too loose.
18. Description of LEDs
LED1
• Flashes briefly: 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
