CAUTION! - 

The mechanical 

stop screw limits handwheel 
operation ONLY and is NOT to 
be used as an electrical travel 
limiting device.

This actuator has been factory calibrated and tested to stop at 0 degrees for CW position and to stop at 90 degrees 
for CCW position. Most installations onto valves or dampers will likely not require recalibration of these settings. Please 
mount the valve or damper and proceed on these pages 

only

 if adjustments are required. Note that for most actuators 

these positions are independent - for instance the CW position is accurate while the CCW position might need adjustment.

 

WARNING – 

Serious Damage to the actuator will result if the motor is allowed to drive the gear train into the

mechanical stop! Remove power from this device BEFORE making any travel adjustments.

Reposition Mechanical Stop
1. Disconnect power.

2. Loosen the RIGHT SIDE mechanical stop. This is the CW mechanical stop

limit adjustment. Using a 17mm wrench and a 5mm hex key, hold the jam
nut and turn the stop screw 5-6 turns CCW so it clears the mechanical boss
inside the actuator.

This will allow you to adjust the cam/switch stop position
without running into the mechanical stop screw.

3. Use the manual override handwheel to position the actuator to your required 

CW position. Keep all changes /- 3 degrees of the factory setting.

Adjust CW Cam (Bottom)

4. Cam 1 is the bottom cam (red) and is the end-of-travel adjustment for the 

actuator CW position. With POWER OFF and the actuator at its required 
CW position, use a sharp 2.5mm hex key to free up the cam set screw. 

Take care not to let the hex key slip at this stage, it can easily strip out. 

Once it is free adjust it as described below: 

Rotate the hex key to the RIGHT 10-15
degrees until you hear a click. This will
reset the switch roller arm.

Gently tighten (CW) the set screw only
until slight pressure is felt. Ideally the
set screw rides along the camshaft.

Now SLOWLY rotate the hex key to the
LEFT, pushing the cam, until you hear
the “click” on the bottom switch. The
click means correct adjustment has
been achieved.

Tighten the cam set screw.

5. Apply power

 and test for the correct CW position:

Drive the actuator CCW at least 15-20 degrees.

Drive the actuator CW until the cam stops the electrical travel.

Check to be sure this is the correct CW position you require.
Repeat the steps of item 4 if further adjustment is needed.

Tighten Mechanical Stop

1. With the actuator in the proper position. Hold the 17mm wrench on the

RIGHT SIDE jam nut to prevent the jam nut from locking and turn the 5mm
hex key CW until the end of the stop screw bottoms out against the internal
stop boss.

2. Turn the hex key ONE FULL TURN CCW and lock this position with the jam

nut. Now the actuator will reach its end of travel electrically before there is
any interference from the mechanical stop.

3. CW position calibration is now complete.

Cam 2 - CCW Cam

CCW Mechanical Stop

Reposition Mechanical Stop
1.  Disconnect power.

2.  Loosen the LEFT SIDE mechanical stop. This is the CCW mechanical stop 

limit adjustment. Using a 17mm wrench and a 5mm hex key, hold the jam 
nut and turn the stop screw 5-6 turns CCW so it clears the mechanical boss 
inside the actuator. 

This will allow you to adjust the cam/switch stop position 
without running into the mechanical stop screw.

3.  Use the manual override handwheel to position the actuator to your required 

CCW position. Keep all changes /- 3 degrees of the factory setting.

Adjust CCW Cam (Second from Bottom)

4.  Cam 2 is the second cam up from the bottom (green) and is the end-of-

travel adjustment for the actuator CCW position. With POWER OFF and the 
actuator at its required CCW position, use a sharp 2.5mm hex key to free 
up the cam set screw. 

Take care not to let the hex key slip at this stage, 

it can easily strip out. 

Once it is free adjust it as described below: 

Rotate the hex key to the LEFT 10-15 
degrees until you hear a click. This will 
reset the switch roller arm. 

Gently tighten (CW) the set screw only 
until slight pressure is felt. Ideally the 
set screw rides along the camshaft.

Now SLOWLY rotate the hex key to the 
RIGHT, pushing the cam, until you hear 
the “click” on the bottom switch. The 
click means correct adjustment has 
been achieved. 

Tighten the cam set screw.

5.  Apply power

and test for the correct CCW position:

Drive the actuator CW at least 15-20 degrees.

Drive the actuator CCW until the cam stops the electrical travel. 

Check to be sure this is the correct CCW position you require.
Repeat the steps of item 4 if further adjustment is needed. 

Tighten Mechanical Stop

1.  With the actuator in the proper position, hold the 17mm wrench on the 

LEFT SIDE jam nut to prevent the jam nut from locking and turn the 5mm 
hex key CW until the end of the stop screw bottoms out against the internal 
stop boss. 

2.  Turn the hex key ONE FULL TURN CCW and lock this position with the jam 

nut. Now the actuator will reach its end of travel electrically before there is 
any interference from the mechanical stop.

3.  CCW position calibration is now complete.
