Basic safety notes The actuators may only be operated by skilled and authorized operating personnel. Make sure to follow all security advices mentioned in this manual, any national rules for accident prevention, as well as the owner´s instructions for work, operation and safety. ...
3. Storage Proper storage means: Only store the actuators in ventilated, dry rooms. Store the actuators on shelves, wooden boards, etc., to protect them from floor moisture. Cover the actuators with plastic foil to protect them from dust and dirt. ...
Installation dimensions Outdoor usage: When using actuators in environments with high temperature fluctuations or high humidity, we recommend using a heating resistor. Figure 2: installation position The actuator may be mounted in any desired position except “cover facing downwards”. 6. Manual operation The hand wheel allows manual operation in case of power failure or during adjustments (Mounting or positioning the valve).
Please protect all of the power supply and control cables in front of the terminals mechanically by using suitable measures against unintentional loosening. Never install the power supply and the control cables together in one line but instead please always use two different lines.
Two adjustable limit switches are installed to limit the stroke of the actuator, and cut-off the motor current in the relative direction. Most motors have a thermal switch, depending on the actuator type, to cut off the current in both directions when a maximum temperature is reached (only at standard single phase power supply).
9. Setting the mechanical stop There is one adjustable screw available for setting the mechanical limit of the 90° angular stroke. When setting the mechanical end positions, only the handwheel may be used. Do not operate the actuator electrically. Remove the protection cap (Figure 6;...
Run the actuator electrically to the closed position until the required position is reached. Turn the cam of the CLOSE limit switch (Figure 8, Pos. 1) with a suitable srew driver (4 mm blade width) anti- clockwise until the micro switch is heard to click. ...
