1. Symbols and safety General dangers of non-compliance with safety regulations PSF-Q-M 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-Q-M 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.
Mounting positions Outdoor usage: When using actuators in environments with high temperature fluctuations or high humidity, we suggest a heating resistor to be fitted to prevent the build-up of condensation within the enclosure. Figure 2: Mounting positions 5. Function The PSF-Q-M electric actuators with manual override are designed for the operation of 90° quarter-turn actuators. For mechanical connection to the valve, the actuators are equipped with flanges according to ISO 5211.
7. Valve mounting The PSF-Q-M actuators are designed with a mechanical interface according to ISO 5211 for valve mounting. The gear contains an exchangeable drive bush to connect the actuator to the valve shaft. Check if the actuator flange suits the valve flange. ...
9. Adjustment of the position indicator The position indicator is a two-coloured half ball turning under a transparent dome with blackened quarter segments. Take off the cover and turn the half ball as appropriate to adjust the position indicator. Figure 6: Adjustment of the position indicator 10.
10.2 Wiring diagram Figure 7 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 7: Electric supply 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, the green LED is flashing 7 times. Push button B1 to return to normal operation. Check the set rotation angle by specifying the setpoint and measuring the actual value. In case of unsuccessful commissioning the green LED is flashing quickly. ...
12.2 Valve curve Switch position S2-10 can be used to select the relationship between the set value and the actuator position. Two curves are available. With the linear valve curve, the actuator position in % corresponds to the set value in %. The "Quick Opening Curve"...
14.2 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. 14.3 Spare parts Damaged actuators should be returned to our plant in Bad Duerkheim, Germany, or to our representatives, to be checked for damages and their possible causes.
