Functions If the actuator is driven by a 3-position signal from the controller, it generates a rotary motion which is transferred to the valve (butterfly, slipper valve, three-port or four-port mixing valve). Direction of rotation of the actuator on delivery: . • Voltage at Y1 = Clockwise rotation . • Voltage at Y2 = Anti-clockwise rotation • No voltage = No rotation; actuator fixed in relevant position The direction of rotation can be reversed if required. Extending the actuator •

Mounting Mounting instructions are enclosed with the mounting kit. The valve, actuator and mounting kit are packed separately. The valve and actuator can be assembled easily on site. There is no need for special tools or calibration. Take care to install the valve the right way up. Refer to the mounting instructions for the valve concerned (butterfly or slipper valves). . .

Setting the angle of The angle of rotation is factory-set to 90°. However, the angle can be changed to rotation between 70° and 180°. This may be necessary when using non-Siemens valves. Special notes on this subject will be found in the mounting instructions for the ASK40 and ASK41 (mounting kits for non-Siemens valves). Maintenance . The actuators require no maintenance. When servicing the valve and/or actuator: switch OFF the pump and power Warning ! supply, close the main shut-off
