Note:
The accelerating function (forceful closing) is only activated for the standard drive
mechanism.
4.7.1
Accelerating force
While an installation is in the state “without mains power” or in the operating mode MANUAL,
the motor acts as an attenuator, thus guaranteeing a constant closing speed until the Closed posi
-
tion is reached.
To make sure that, when switched to the de-energized state or in the operating mode MANUAL,
the door leaf is reliably engaged by the door lock, the drive mechanism is equipped with a door
slam function (acceleration causing a forceful closing). By means of the potentiometer, the motor
attenuation (shortly before the door leaf reaches the closed position) can be adjusted so that the
pressure spring will have sufficient power for pushing the door leaf safely into the door lock.
Procedure:
1. Open the door leaf by 90° and then let it be closed.
2. Should the door leaf fail to engage in the lock, adjust the door slam cushioning by means of
the potentiometer (provided on the control unit).
Warning:
In de-energized state or in the operating mode MANUAL, the closing procedure must
last at least 3 seconds (from the open position 90° up to the closed position 0°).
