· If the actuator is forced to travel beyond its end positions, overload protection
responds.
· Observe information given in chapter 4.2.1 Positioning signal and flow
characteristic selection, page 31.
Before making the function check, the following preconditions must be satisfied:
· "Environmental conditions" specified in chapter "Technical data" (page 45).
· Actuator is mechanically connected to a Siemens valve.
· Actuator is in “Automatic” mode (page 42).
· Actuator and, if required, accessories are correctly fitted and connected. Also
refer to chapter
·
· Connection terminals” (page 48) .
· 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 4.2.3 Calibration
(page 32).
