Manual Operation
3. After manual operation, leave the lever as is. When
power is re.applied to the actuator, the lever will disengage
and declutch the manual override. The actuator motor vill
then rotate the valve to the powered position.
4. If the lever does not “Lock” in the manual position while
trying to manually operate the actuator, then the actuator
gearing may be jammed and needs to be checked.
1. Pull the lever located on the side of the actuator toward
the hand wheel. The lever should “Lock” in position.
Rotate the hand wheel and the actuator output will rotate.
Fig. 1
2. If the lever does not “Lock” in the upright position, then
turn the hand wheel halfway and pull lever to the right
position.
· Rotate the hand wheel clockwise for CLOSE
· Rotate the hand wheel counter clockwise for OPEN
