3.2 Commissioning and operation
3.2.1 Function check and Calibration
Before making the function check, the following preconditions must be satisfied:
· Environmental conditions specified in chapter "Technical data" (page 73)
· Actuator is mechanically connected to a Siemens valve
· Actuator is in "Manual operation" mode (page 69).
The actuator can be operated with the help of the "Manual adjuster" (see page 69).

· Ensure that the actuator’s and valve’s stem, or actuator’s and valve’s spindle are
securely connected in all positions.
· If the actuator is forced to travel beyond its end positions, overload protection
responds.
· Observe information given in chapter "Acting direction and flow characteristic"
on page 57.
Before making the function check, the following preconditions must be satisfied:
· Environmental conditions specified in chapter "Technical data" (page 73).
· Actuator is mechanically connected to a Siemens valve.
· Actuator is in "Automatic" mode (page 69).
Actuator and, if required, accessories are correctly fitted and connected. Also refer
to "Connection Terminals” (page 77)
· Power is applied.
Calibration is required with modulating actuators and SA..61.. before the function
check.
Before making the calibration, the following preconditions must be satisfied:
· A description of the calibration function is given in chapter "Calibration" (page 59
for non-Modbus actuators, page 63 for Modbus actuators).
· Housing cover is removed (step 6 "Special notes on mounting", page 35).
