H. SETTING LIMIT CAMS
• The limit cams are adjusted by loosening the locking screws and rotating the cams. The cams
rotate with the swing arm shaft, so small adjustments are magnified by the length of the gate.
• The gate operator torque limiter allows the gate to be pushed or pulled a short distance (a few
inches) only. Use manual controls to move the gate during limit cam adjustment.
• To avoid damage to the gate and gate operator due to the gate overrunning its limits, perform
the following steps carefully:
1. SETTING RIGHT GATE LIMIT CAMS
Figure 7. Setting Right Gate Limit Cam.
1. Make sure that switch S2 is set to the "Left" position.
2. Turn on gate operator power switch.
3. Using manual CLOSE and STOP, move the gate to its proper closed limit position.
4. Loosen the locking screw on the bottom limit cam and turn the cam clockwise until it just barely
closes the limit switch.
5. Retighten the limit cam locking screw.
6. Using manual OPEN and STOP, move the gate to its proper open limit position.
7. Loosen the locking screw on the top limit cam and turn the cam counterclockwise until it just
barely closes the limit switch.
8. Retighten the limit cam locking screw.
9. Open and close the gate to check the limit cam settings. If required, readjust the limit cams
until they are set properly.
