MOUNTING
4.1
Preparation
Attention:
Standard application
It is recommended that a door leaf stop piece be mounted by the customer.
Inverse application
It is imperative for the customer to install a door leaf stop piece!
This stop piece prevents the door leaf from being damaged in the manual operating
mode. As an option, an open position stop piece can be integrated into the drive me
-
chanism itself.
1. Check the free running movement of the door leaf.
Should it fail to move smoothly and silently, or if it is out of balance (i. e. it opens or closes by
itself), these problems must be eliminated first!
Attention:
The motor connector plug must be re-connected in the control unit, according to the
respective mounting version (Y = standard
see chapter 4.2 Mounting versions). This
in order to ensure the cushioning function.
2. Loosen the two screws (A).
3. Pull the control (B) out from under the
gearbox housing (C).
4. Re-connect the motor connector plug (D).
5. Remount the control unit (B).
