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 |
• |
The SQK33.00 actuator can be fitted with an auxiliary switch |
||
functions |
• |
The SQL… actuators can be fitted with an auxiliary switch, a dual auxiliary switch or |
||
|
|
an auxiliary switch and a 1000-ohm potentiometer. |
||
If an auxiliary switch and/or potentiometer are fitted, the electrical wiring must take account of this. Refer to the wiring diagram under the actuator cover and see also the "Commissioning" and "Connection diagrams" sections in this data sheet.

*) Mounting kits ASK40 and ASK41 for non-Siemens actuators: refer to data sheet N42291
Mechanical design
The electric actuators require no maintenance. They have a reversible synchronous motor and reduction gears with self-lubricating sinter bearings. The housing base and the console are die-cast aluminium, and the cover is plastic.
"AUTO" and "MANUAL" modes can be selected with a rotary switch on the housing base. When the switch is set to "MANUAL", the actuator and valve can be operated with a manual lever. For manual operation, the angle of rotation is mechanically limited by an end-stop.
The actuators supplied have a 90° angle of rotation suitable for the Siemens valves. During automatic operation, rotation is limited by two built-in end-switches. For nonSiemens valves, the angle of rotation in the range 70° to 180° can be selected by repositioning the switching cams.
The direction of operation of the actuator can be reversed (refer to "Commissioning").
