Title: Siemens STA73-eng.pdf
The actuator stem extends and the small valve, V..P47.., is opened. The position of the stem is proportional to the DC 0…10 V positioning signal. The actuator stem retracts when de-energized and the small valve is closed by the own spring. The actuator deploys to the 50% stroke position if the positioning signal is lost when applying operating voltage. DC 0…10 V actuators support various operation modes, see also under DIP- Switch settings7 / 16Siemens Building TechnologiesElectrothermal actuators STA..3.., STP..3..CE1N4884en 03.05.2012STP63../STP63..
