LIMIT SWITCH ADJUSTMENT
Adjustment of door travel is done by moving the limit cams on the threaded shaft. The position of the 4 limit switches are
factory adjusted and should not be altered. The limit switches are:
- “Open” limit switch: End of door travel in the fully open position
- “Closed” limit switch: End of door travel in the fully closed position
- “Advanced Open” or “Auxiliary advanced closed” limit switch:
A) For relay logic operators this advanced open limit switch is used for open/close devices or timer to close features.
B) For logic board this auxiliary closed limit switch is used for open/close devices used when motor direction
is reverse of standard.
- “Advanced Closed” Limit switch: Used to prevent reversing device from reversing door when door is almost fully closed.
To adjust door travel:
1.
Open cycle: Depress cam plate and spin “Open” limit cam away from “Open” limit switch to increase door travel or spin
“Open” limit cam towards the “Open” limit switch to decrease door travel. After each adjustment ensure that cam plate
fully engages in slots of both limit nuts.
2. Adjust “Open” limit cam so that door stops at the desired fully open position.
3. Close cycle: Depress cam plate and spin “Close” limit cam away from “Close” limit switch to increase door travel or spin
“Close” limit cam towards the “Close” limit switch to decrease door travel. After each adjustment ensure that cam plate
