Installation
WARNING!
Risk of injury from improper installation.
▶
Installation may be carried out by authorised technicians
only and with the appropriate tools.
Risk of injury from unintentional activation of the system and
an uncontrolled restart.
▶
Secure system from unintentional activation.
▶
Following assembly, ensure a controlled restart.
Procedure:
→
Specify the attachment position of the positioner:
- parallel to the actuator or
- rotated by 90° to the actuator.
→
Determine home position and direction of rotation of the
actuator.
Anti-twist safeguard:
Note the flat side of the axle!
One of the setscrews must be situated on the flat side of
the axle as an anti-twist safeguard (see “Fig. 13”).
→
Connect adapter
①
to the axle of the positioner and secure
with 2 setscrews.
→
Secure setscrews with self-locking nuts to prevent them from
working loose.
Angular range of the position sensor:
The maximum angular range of the position sensor is
180°. The axis of the positioner should only be used within
this range.
Ideal position
for the rotational range
of the levelled shaft. (min
30°/max 180°)
The rotational movement of the
levelled shaft must be within the
position sensor angular range of 180°.

Assemble the multi-part assembly bridge suitable for the
actuator. The assembly bridge consists of 4 parts, which can
be adjusted to the actuator by varying the arrangement.
