A 5 mm Allen (Hex.) key and 0.8 x 4 mm flat screwdriver are 
required to perform commissioning of the CK Mechanical 
Switch Mechanism.

Set torque limits

Indicator/Adjustment Point

Torque Cam Clutch Screw

1)  Move the valve to a mid-travel position and loosen the 

Torque Cam Clutch 1.5 turns using a flat screwdriver.

2)  Adjust each Torque Cam to the desired value (between 

min. & max.) by moving the cam using a screwdriver on the 
adjustment point.

 CAUTION: Ensure the screwdriver remains 

perpendicular to the switch mechanism faceplate 
when adjusting the torque trip limits to avoid 
introducing an offset to the set value.

3. Commissioning

  Close Torque Adjustment Point

3)   Tighten the Torque Cam Clutch Screw once both torque 

trip limits have been set.

 CAUTION: Ensure the Torque Cam Clutch Screw is 

tightened enough to fully deform the spring washer 
underneath the screw head.

  Factory Calibration Fixings

 WARNING: Do not adjust the fixings or position 

of the yellow torque indicator plates. These are 
factory configured for 40-100% adjustment of the 
actuator torque and under no circumstances should 
be moved.
