Manual 35183
Manual Drive Access Plug
The actuator can be mechanically stroked and aligned to a mechanical position by use of a manual drive.
1.
To access the drive first remove the manual drive access plug below the motor per the image below.
2. After removing the plug, rotate the gear train by inserting a 0.75" hex drive and turning the motor and
pinion gear to the desired position.
Note: The extended and retracted internal mechanical hard stops can be found by turning the drive until it
stopes when 2.5 ft-lbs is applied. The actuator drive should rotate and move the shaft with less than
1.5 ft-lbs applied to the drive. Do not apply more than 10 ft-lbs to this drive or damage can occur to the
actuator. The 0% electrical position is set 1 motor turn away from the hard stop position (where the hard
stop position is measured at 2.5 ft-lbs).
3.
Replace the manual drive access plug when you are finished.
