7 Mechanical assembly and configuration

CAREFUL
Safe operation of the elevator door actuator requires that it is properly assembled and put into
operation by qualified staff, with due attention to the warning notices of this operating manual.
Before all work on the door actuator it is to be ensured that the controls are without power.
Only then is an immobility of the door guaranteed. The mechanical assembly and setting of the
elevator door actuator takes place in the following steps:
1. Mount the motor on the motor mounting (rubber-bonded metal/vibration shock
mount). Thereafter the motor is mounted on the mounting bracket if necessary.
. Mount the overhead pulley, if necessary with mounting bracket. Make sure of the
alignment of the drive pinion and the overhead pulley; these should be aligned with
each other as precisely as possible.
3. Bolt the timing chain and the door clutch holder together and set it up.
NOTICE
Use the door clutch holder (timing chain lock) as described in the attachment exclusively! Through
an improper fastening a notch effect can be effected on the timing chain, which can lead to the
destruction of the timing chain! The door clutch holder (timing chain lock) may not run through the
pinion drive or the overhead pulley!
4. Tighten the timing chain with the aid of the tensioning device. The correct
tension is achieved when the timing chain can be pushed in by approximately 3 cm
per every meter distance in the middle between the drive pinion and the overhead
pulley.
5. Mount the control unit close to the drive motor
(take length of cable into account).
6. Mount the transformer close to the control unit
(take length of cable into account).
CAREFUL
In case of a fault or a short circuit of the outlet cable of the transformer the housing temperature
can rise to above 105° C.
Because of this the transformer may only be mounted on surfaces, where no danger of combustion
exists and touching by unauthorised persons is not possible.
The service staff should be notified of this fact.
