Installation, Adjustment & Maintenance

16 of 31

1)Determine the direction of rotation of the cranks. In a standard installation, the cranks pivot toward the motor, and the roadway.

The limit switch cams rotate the same direction that the pivot rotates. Cam 1 is always the raise stop, Cam 2 is always the lower stop, Cam 3 generally controls the arm lights if there are any.

IMPORTANT: Always power down at the main switch before adjusting the limit switches.

2)Manually rotate the barrier into its fully open to traffic (raised) position by inserting the manual crank onto the shaft extending from the top of the motor and turning it until the barrier reaches the desired position.

Note: At fully open, the connecting rods should be parallel with the sides of the operator and with the cranks. The cranks should be pointing straight up.

3)With an allen wrench loosen the limit switch cams just enough so that they will turn, but not so much that they are loose.

4)Rotate Cam 1 until the limit switch follower just falls off of the edge of the cam. Keep the direction of rotation of the cam in mind as you set it to ensure that when the barrier rotates, the limit switch follower will move back onto the cam.
