LIMIT SWITCH ADJUSTMENT
Make sure the limit cams are positioned between the limit switch actuators before proceeding
with adjustments.
1. Open / Remove the control panel cover.
2. Open or close door to determine the moving direction of the limit switch cams.
3. Open or close door to the desired position.
Disconnect power before adjusting limit switch cams.
4. While pressing the spring-loaded lever (G), which holds the limit switch cams in place, adjust the limit
switch cam (E or F) until the micro switch (C or D) clicking sound is heard.
5. If the limit switch cam cannot be rotated to its desired position, release the lever and move the door
away from the desired position, then adjust the limit switch cam to its desired position. It may be
necessary to repeat this step until the exact position has been reached.
6. Repeat step 3 and 4 for the opposite position. Adjust close limit cams so that actuator is engaged as
door fully seats at the floor.
7. Micro switch (A or B) can be adjusted to accommodate sensing edge cut-off position.
