The limit switches are now roughly adjusted. If the gate should stop
short of fully opened or closed, or if it bangs against the end stops
during operation, the limit switches can be fine-tuned after the operator
is powered up. (See FINAL SETTING OF THE LIMIT SWITCHES, P.
16.)
SETTING THE LIMIT SWITCHES
Before turning on the main power, set the limit switches which are
located on top of the frame, between the control box and the reducer
gearbox. See Figure 18. In a right-hand installation, the switch nearest
the control box is the open limit switch. In a left-hand installation, the
switch closest to the gearbox is the open limit switch.
Manually push the gate all the way open. Press down on the spring
loaded detent plate and rotate the open limit nut toward the open limit
switch contactor until you hear the open limit switch click. Rotate the
limit nut two more slots to give the operator time to stop the gate after
the limit switch has been activated. Release the detent plate and make
sure it drops into the slots on both limit nuts.
Manually push the gate all the way closed. Depress the detent plate and
rotate the close limit nut clockwise until the close limit switch clicks.
Again rotate the close limit nut two more slots. Release the detent plate
and make sure both limit nuts are firmly seated.

THE MOTOR WIRE CONNECTOR AND THE LIMIT
HARNESS CONNECTOR MUST BOTH ALWAYS BE IN
EITHER THE RIGHT OR LEFT POSITIONS. IF ONE IS
IN THE RIGHT POSITION AND THE OTHER IN THE
LEFT POSITION, THE OPERATOR WILL NOT STOP
THE GATE WHEN IT REACHES THE END OF TRAVEL.
