REPLACING AND ADJUSTING LIMIT CAMS IN A RESTRICTED INSTALLATION

Figure 14.  Setting Limit Cams For A Restricted Installation.

1.  Make sure that switch S2 is set to the "Right" position.

2.  Turn on gate operator power switch.

3.  Using manual CLOSE and STOP, move the gate to its proper closed limit position.

4.  If not already loose, loosen the locking screw on the right limit cam and turn the cam clockwise

until it just barely closes the limit switch.

5.  Tighten the right limit cam locking screw.

6.  Using manual OPEN and STOP, move the gate to its proper open limit position.

7.  If not already loose, loosen the locking screw on the left limit cam and turn the cam counter-

clockwise until it just barely closes the limit switch.

8.  Tighten the left 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.
