1. Symbols and safety General dangers of non-compliance with safety regulations PSF actuators are built at state-of the art technology and are safe to operate. Despite of this, the actuators may be hazardous if operated by personnel that has not been sufficiently trained or minimum instructed, and if the actuators are handled improperly, or not used as per specification.
2. Usage as per specification PSF actuators are exclusively designed to be used as electric valve actuators. They are meant to be mounted on valves in order to run their motors. Any other use is considered to be non-compliant and the manufacturer cannot be held liable for any damage resulting from it.
Installation position Outdoor usage: When using the actuators in environments with high temperature fluctuations or high humidity, we recommend using a heating resistor. Figure 2: Installation positions 5. Function The PSF actuators are designed as electric valve actuators with failsafe function. The actuator is mounted onto the valve via pillars.
8. Removing / closing the cover Open the cover only in a dry environment. Attention! Observe precautions for handling. Ground the actuator. Before opening the cover, touch grounded housing parts. Open: Loosen the screws by using a screwdriver and unscrew them entirely out of the gear casing.
9.2 Wiring diagram Figure 6 indicates the electrical connections for standard actuators. The wiring diagram inside the actuator is binding for the specific actuator wiring. For any optional accessories, see the separate wiring diagram in the corresponding installation instructions. *optional Figure 6: Wiring diagram PE earth connection has to be connected to gear casing at Ensure that all connecting cables are stripped to the correct length so that they are protected...

After successful commissioning, check the found or adjusted stroke by comparing the set value and the valve position. In case of unsuccessful commissioning the green LED is flashing quickly. Please check valve mounting. For commissioning, a stroke of at least 1 mm in direction “close with force” is required before the actuator has reached its mechanical stop.
13.2 Maintenance The actuators have a pre-tensioned spring inside, the gearbox housing must not be opened. Defective actuators should be returned to our plant in Bad Duerkheim, Germany, or to our representatives, to be checked for damages and their possible causes. 13.3 Spare parts Damaged actuators should be returned to our plant in Bad Dürkheim, Germany, or to our representatives, to be checked for damages and their possible causes.
