Mechanical mounting 
Position of actuator bolt 
The actuator bolt for moving the potentiometer lever can be 
mounted permanently on the lever itself or on the valve stem. 
Depending on the mounting method, when the valve moves the 
actuator bolt performs either a circular or a linear movement 
with reference to the center of rotation of the potentiometer 
lever. Select the chosen bolt position in the HMI menu in order to 
ensure optimum linearization. The default setting is actuator 
bolt on lever.

Mounting on rotary actuator 
For mounting on part-turn actuators in accordance with 
VDI / VDE 3845, the following attachment kit is available: 
M10130-01
Figure 14: Components of attachment kit 
• Adapter 1 with spring 5
• four M6 screws each 4, spring washers 3 and washers 2
to fasten the attachment bracket 6 to the positioner 
• four M5 screws 7, Spring washers 8 and washers 9 to 
fasten the attachment bracket to the actuator 
Required tools: 
• Wrench, size 8 / 10 
• Allen key, size 3

Figure 15: Mounting the adapter on the positioner 
1. Determine the mounting position 
(parallel to actuator or at 90° angle) 
2. Calculate the rotational direction of the actuator 
(right or left). 
3. Move the part-turn actuator into the home position. 
4. Pre-adjust feedback shaft. 
To make sure that the positioner runs within the operating 
range (refer to General on page 13), the mounting position as 
well as the basic position and rotation direction of the 
actuator must be considered when determining the adapter 
position on axis 1. For this purpose, the feedback shaft can 
be adjusted manually so that the adapter 3 can be attached 
in the correct position. 
5. Place the adapter in the proper position on the feedback 
shaft and fasten with threaded pins 2. One of the threaded 
pins must be locked in place on the flat side of the feedback shaft.

After mounting, check whether the operating range of the 
actuator matches the measuring range of the positioner, refer to 
General on page 13.

Safety instructions 
DANGER 
Risk of explosion for devices with local communication 
interface (LCI) 
A local communication interface (LCI) may not be operated in 
hazardous areas. 
• Never use the local communication interface (LCI) on the 
main board in a hazardous area! 
WARNING 
Risk of injury due to live parts! 
When the housing is open, contact protection is not provided 
and EMC protection is limited. 
• Before opening the housing, switch off the power supply. 
The electrical connection may only be established by authorized 
specialist personnel. 
Notices on electrical connection in this instruction must be 
observed; otherwise, electric safety and the IP-rating may be 
adversely affected. 
Safe isolation of electric circuits which are dangerous if touched 
is only guaranteed when the connected devices fulfill the 
requirements of EN 61140 (basic requirements for secure 
separation). 
To ensure safe isolation, install supply lines so that they are 
separate from electrical circuits which are dangerous if touched, 
or implement additional isolation measures for them.
