6. The door opens, but does not close:
• If installed, the photocells should be checked. If the LED at the photocells
blink, the alignment should be checked.
• Check remote control 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 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,
reprogramme 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 belt rattles on the rail:
• Adjust the belt tension. The cause is usually a very tight chain/belt.
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 belt 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 disengaged?
• 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. Setting the Force
The force setting button is located behind the cover at the operators
backside. The force setting regulates the amount of power required
to open and close the door.
1. Open cover on the backside of the opener.
Locate the yellow round button (2).
2. Push the yellow round button (2) twice to enter unit into Force
Adjustment Mode. The LED (3) (indicator light) and the UP button will
flash. Push UP button. The operator will travel to the UP position
learning the required amount of force. Once the UP limit is reached the
LED and the DOWN button a start to flash. Push DOWN button.
The operator will travel to the DOWN position learning the required
amount of force.
