Mounting positions
When commissioning the system, check the wiring and functions, and set any auxiliary
switches and potentiometers as necessary, or check the existing settings.
Cylinder with valve stem
connector fully retracted
→ stroke = 0 %
Cylinder with valve stem
connector fully extended
→ stroke = 100 %
The manual adjuster must be rotated counter-clockwise to the end stop.
This causes the Siemens valves, types VVF.. und VXF.. to close (stroke = 0 %).
Automatic operation
For automatic operation, the crank [2] on the manual adjustment knob [1] must be engaged.
If not engaged, turn the crank counter-clockwise until the display window [3] shows neither
the scale [4] nor the crank engagement bar.
