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.  
 

• 

The SQK33.00 actuator can be fitted with an auxiliary switch 

• 

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.
