Attention:
During operation, the actuator and/or coupling move with substantial force. Risk of
injury! Keep your hands off the actuator!
Compressed-air supply:
To achieve trouble-free operation of the position controller, dry, clean, and
oil-free instrument air is required.
Required compressed-air quality as per ISO/DIS 8573-1:
• Size and density of solids: Class 2
• Pressure dew point: Class 2 (minimum 20 K below ambient temperature)
Travel limiting
travel limiting function of the actuator must be performed according to Samson
’s data sheet.
Alignment of the actuator
If the actuator is in an unsuitable position to install the cables and the connection for the position / end
switch, the alignment can be adjusted by turning the yoke of the actuator.

Electrical and pneumatic additional components
If applicable, electrical signal values are defined in the technical drawings.
Initialization of the position controller:
The valves are already initialized with the positioner.
WEKA AG recommends re-initializing the position controllers during commissioning
of the valves. For instructions for this process, either contact WEKA AG or download
them directly from the homepage of the position controller supplier.
Various extra components
The valves can be equipped with various extra components, such as sensors,
switches, solenoid valves, etc. Connect the components to your monitoring system.
For instructions of this process either contact WEKA AG or download them directly
from the homepage of the component manufacturer.
