Having a problem?
1. Pull the manual release handle to disengage the trolley.
2. Lift the door about halfway. Release the door. It should stay in place, supported entirely by its springs.
3. Raise and lower the door to see if there is any binding or sticking. If your garage door binds, sticks or is out of balance, call a
professional garage door service engineer.
ISSUE POSSIBLE REMEDIES
Operator moves only in OPEN
direction but not in CLOSE
direction
Operator doesn’t fully open the
door to the marked position. It
stops and reverses.
Operator doesn’t fully open the
door to the marked position. It
stops but doesn’t reverse.
The connection arm can’t be
installed between door and
operator.
Door can be opened with the
operator but cannot be closed
from the open position. The
operator moves a little (appr. 1
sec) and then reverses.
The door touches the rail
• The travel distance hasn’t been programmed at all or hasn’t been programmed properly.
Only possible when installed for the first time.
• Some models will only close the door, if photocells are connected. In this case photocells
are included.
• Release operator and check if it closes. If so, do the force adjustment
• The marked position is too close to the operator. Because of the operator this position can’t
be used. Some doors can’t be opened to the full horizontal position. Readjust travel distance
(shorter).
• The force adjustment hasn’t been programmed properly and the operator moves inefficiently.
• Doorarm must be fully extended shortly before reaching its final position. If it’s not, check
the distance between rail and door.
• Door is too heavy or insufficiently balanced in OPEN direction. Rebalance door (call a
trained technician or have it repaired) Grease track rollers and hinges.
• Travel distance too short. Readjust!
• Doorarm screws were not tightened.
• Door is distorted.
• Is the operator properly installed (just above the door) ?
• Is the doorarm properly installed?
• Doorarm must be fully retracted when the door is closed.
• Operator reverses because the adjusted force is lower than the required force. Readjust
force. Test: Standing in front of the door you can „help“ the door to move from the open
position by pulling at the door for the first 50cm. This confirms that the adjusted force was
too low.
• The door has passed over the horizontal position and is facing upwards. In this case
readjust travel distance (shorter).
• If the operator will close the door during the force learning but doesn’t close the door later
on, this is due to a bumpy not smooth running door.
• Remedies:
• A: Readjust travel distance. Do not open door too far.
• B: The spring pulls the door upwards strongly and therefore the door is unbalanced. The
operator now requires too much force in order to move the door down. Diminish (readjust)
tension of door spring.
• C: Rail vibrates due to high force. Aspacer (e.g. a piece of wood) between ceiling and rail
avoids vibrating and bending of the rail.
• The remedies mentioned may occur combined.
• If the door functions properly and is well balanced then also the operator will function
properly.
In rare installations, the canopy door may touch the operator rail when closing. This is NOT
the fault of the operator or arm. If this occurs:
1. Manually check the operation of the canopy door to ensure that it is closing easily. The
door must have a slight drop at the start of closing.
2. If the door is not running easily, check that the side wires are not catching or binding on the
wire guides. Move the guides until the wires run free.
3. Raise the operator head by about 50mm (2”) vertically so there is a slight downward angle
on the rail.
4. The door spring may be over tensioned.
