LIMIT SWITCHES
The limit switch adjustments are located on the top shelf of the operator. Remove the cover from the operator to
make adjustments. The normal settings from the factory allow for about 15 feet of travel. You will most likely
have to adjust the limits for your installation. To adjust limits press down on the limit plate assembly, this will
release the limit plate from the limit adjustment cams and allow the cams to turn. Turn the limit adjustment
cam, which corresponds to the direction you want to adjust.
NOTE: WHEN THE LIMIT ADJUSTMENT CAM DEPRESSES THE LIMIT SWITCH ACTUATOR
THE GATE WILL STOP.
