ADJUSTING THE LIMIT SWITCHES
Test the operator to verify that the limit switches are properly set. The
operator should open and close the gate completely. After properly setting
the limit switches, the control board must be set according to the operator
application. The system accessories should also be connected to the
control board.
The limit switches determine how far the gate travels to open and close. The closer the limit nut is to the limit switch,
the less distance the gate will travel to open or close. Adjust the limit switches by moving the limit nuts.
MAKE SURE THE OPERATOR POWER IS OFF BEFORE ATTEMPTING TO ADJUST THE LIMIT SWITCHES.
Lift and release the limit switch plate to unlock the limit nuts (see
illustration at right). Using a fingertip, roll the limit nuts along the travel
shaft until the correct open and closed gate positions are determined.
If the operator is mounted to the LEFT of the gate (see illustration
below): the left limit switch adjusts the open position. The right limit
switch adjusts the closed position.
If the operator is mounted to the RIGHT of the gate (see illustration
below): the right limit switch adjusts the open position. The left limit
switch adjusts the closed position.
Lift limit switch plate to release,
then adjust limit nut.
