Commissioning notes
When commissioning the system, check the wiring and functions, and set any auxiliary
switches and potentiometers as necessary, or check the existing settings.

The manual adjuster must be rotated counterclockwise to the end stop, i.e. until
the red indicator marked «MAN» is no longer visible. This causes the Siemens
valves, types VVF.., VVG.., VXF.. and VXG.. to close (stroke = 0%).

Maintenance notes
The SKD.. actuators are maintenance-free.
When servicing the actuator:
· Switch off pump of the hydronic loop
· Interrupt the power supply to the actuator
· Close the main shutoff valves in the system
· Release pressure in the pipes and allow them to cool down completely
· If necessary, disconnect electrical connections from the terminals
· The actuator must be correctly fitted to the valve before recommissioning.
Recommendation SKD6..: trigger stroke calibration.
«Replacement parts», see page 17.
A damaged housing or cover represents an injury risk
· NEVER uninstall an actuator from the valve
· Uninstall the valve-actuator combination (actuating device) as a complete
device
· Use only properly trained technicians to uninstall the unit
· Send the actuating device together with an error report to your local Siemens
representative for analysis and disposal
· Properly mount the new actuating device (valve and actuator)
Parts could fly ultimately resulting in injuries from uninstalling an actuator with a
damaged valve housing due to the tensioned return spring.
Disposal
The device contains electrical and electronic components and must not be disposed of
together with domestic waste. This applies in particular to the PCB.
Legislation may demand special handling of certain components, or it may be sensible
from an ecological point of view.
Current local legislation must be observed.
