CAUTION
National safety regulations
Failure to comply with national safety regulations may result in personal injury and property
damage.
● Observe national provisions and comply with the appropriate safety regulations.
CAUTION
Phase cut and pulse-duration-modulated (PDM) signals are not suitable.
Regulations and requirements to ensure the safety of people and property must be
observed at all times!
Commissioning
When commissioning, check both wiring and functioning of the actuator.
● Actuator stem extends
Valve closes
● Actuator stem retracts
Valve opens
NOTICE
The actuator must be commissioned only with a correctly mounted valve in place!
Self-calibration (SSA161.05 only)
When operating voltage is applied, the actuator self-calibrates (fully retracted ➙ fully
extended ➙ setpoint).
NOTICE
● Correct calibration is only possible with valve stroke > 1.2 mm. Valve stroke < 1.2 mm
results calibration failure.
● If calibration fails, the actuator performs another calibration automatically after
10 seconds.
● After three failed calibration attempts, the actuator stem remains in the extended
position and the valves are closed.
Maintenance
The actuators require no maintenance.
