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°.

Levelled 
shaft

180°

 

Maximum rota-

tional range  

90°

Fig. 13:  Angular range/anti-twist safeguard

 

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.

 

Attach the assembly bridge to the positioner using four 

hexagon bolts 

 and spring lock washers 

 (see “Fig. 14”).
