Force learning cycle
Warning:
During this procedure, the operator automatically learns the normal mechanical force required to
open and close the garage door. Force limits are deactivated until the conclusion of the learning
cycle. Keep a suffi cient distance from the entire path of motion of the garage door!
Do not interrupt this procedure.
Note:
During this procedure the display shows "0".
1. Press the OPEN button (B) or use the set hand transmitter. The garage
door moves from the end position CLOSE to the end position OPEN.
2. Press the OPEN button (B) again or use the set hand transmitter. The
garage door moves from the end position OPEN to the end position
CLOSE.
After approximately 2 seconds, the "0" on the display goes out.
Note: After completing the force learning cycle, the display "0" must go out.
Checking force limit
1. Place a force gauge or obstruction (e.g. the operator's cardboard box) in
the closing area of the door.
2. Close the garage door. The garage door moves to the end position
CLOSE. When the garage door reaches the obstruction, the garage
door must stop and then move back a short distance towards the OPEN
position.
3. If the door can lift persons (e.g. openings greater than 50 mm or treads),
the force limiting unit must be checked in the opening direction: For
additional load of the door with 20 kg of mass, the drive has to stop.
Delete force learning cycle
Note: The force learning cycle always starts from the end position CLOSE.
The force learning cycle must be repeated after each replacement of the
garage door springs:
Proceed to Menu 5 (see special settings) and keep the programming button
(PROG button) (D) pressed for 3 seconds. The number "0" is displayed.
Complete the process as described in the force learning cycle section.
For your safety, we recommend that the door system be checked before initial use and as needed –
but at least once a month – by a specialist. We recommend consulting a specialist company.
