Forceful closing range
Upon delivery from the factory, the activation of the accelerating function (forceful closing) is pre-
set (i.e. it intervenes approx. 5° before reaching the closed position). Under normal conditions, it
will not be necessary to change the default setting! However, in cases where in the de-energized
state or in the operating mode MANUAL the door leaf fails to be reliably engaged in the door lock,
the activation point of the accelerating function (forceful closing) can be shifted (by means of a
continuously adjustable cam disk).
Note:
The setting range is between 5 and 15° of the door opening angle.
Procedure:
1. Using a screwdriver, carefully prize the service cover (C) out of the gearbox housing.
2. By means of a socket wrench 1,5 mm, slightly loosen the locking screw (B), then carefully
turn the cam disk (A) to the left or to the right.
3. Tighten the locking screw (B).
4. Open the door leaf by about 45° and then let it be closed. Check whether the door leaf is
correctly pushed into the door lock.
5. Snap the service cover (C) into the gearbox housing.
