Mechanical Limit Stop Setting
In the event of a limit switch malfunction, the mechanical
limit stops will prevent the actuator from over traveling and
causing damage to the valve. The mechanical limit stops
should be reset whenever any adjustment is made to the
open and closed limit switches, this will protect the valve in
the event of any electrical malfuntion.
1. Turn the power off to the actuator. Engage the manual
override and fully close the valve clockwise.
2. Turn the mechanical limit stop into the body until contact
is made between the limit stop and worm wheel. After
contact is made, turn the limit stop back out two turns and
lock it in place with the nut by tightening the nut against
the body. Fig. 3

3. To set the open limit stop, follow the above instructions
except rotate the actuator in the counter clockwise
rotation.
If the mechanical stops are improperly set,
motor and gear damage may occur.
After setting the limit stops, check for proper
function by operating the actuator both manually
and electricly. Conrm that the end of travel limit switches
shut off power to the motor in both the open and closed
positions, and that the motor is not stalled or in an over-
torque condition.
