Mechanical installation and setting

CAUTION
Safe operation of the elevator door drive requires proper assembly and commissioning by
qualified personnel, with due attention given to the warning notices in the operating
instructions.
The controller must be disconnected from the power supply before starting any work on the
door drive. Only then is immobility of the door guaranteed.
The mechanical assembly and setting of the elevator door drive are performed in the
following steps:
1.
Mount the motor on the rubber-metal anti-vibration motor mounting.
Then, if necessary, mount the motor on the mounting bracket.
2. Mount the deflector pulley, if necessary with a mounting bracket.
Align the drive pinion and the deflector pulley as precisely as possible with each other
(flush).
3. Bolt the toothed belt to the door clutch holder, and put it in position.
Note
Only install the door clutch holders (toothed-belt joint) specified in the Appendix.
Unsuitable fastenings can concentrate the stress on the toothed belt, which can lead to
its destruction. The door clutch holder (toothed-belt joint) must not run over or touch the
drive pinion or deflector pulley.
4. Tension the toothed belt with the aid of the tensioning device. The correct tension has
been reached when the midpoint of the toothed belt can be pushed in by approximately 3
cm for every meter of distance between the drive pinion and the deflector pulley.
5. Mount the controller close to the drive motor (take the length of the cable into account).
Observe the permissible ambient temperatures, and take action to remain within the limits
when necessary.
