3.2.1 Function check and Calibration
Before making the function check, the following preconditions must be satisfied:
Mechanica
lly
• "Environmental conditions" specified in chapter "Technical data" (page 50)
•
Actuator is mechanically connected to a Siemens valve
•
Actuator is in "Manual operation" mode (page 46).
The act
uator can be operated with the help of the "Manual adjuster" (see page 46).
