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.
Repair The actuators cannot be repaired; the complete unit must be replaced. Disposal The device is considered an electronic device for disposal in accordance with European guidelines and may not be disposed of as domestic waste. ● Dispose of the device through channels provided for this purpose. ● Comply with all local and currently applicable laws and regulations. Warranty Technical data on specific applications are valid only together with Siemens products listed under "Equipment combinations".
