PROGRAMMING

Program Limits

The limits are internal settings that indicate to the control board when the gates are in the fully Open position and the
fully Closed position for your specific installation. For proper functionality, the limits need to be learned during the
installation process. The learn limit process uses a combination of buttons on the control board.
The specific buttons used for learning limits depends on which side of the gates your control box is mounted on and how
many operators your installation includes. Refer to pages 11-12 to determine if your installation is Left- or Right-handed
and for explanation of PULL-TO-OPEN and PUSH-TO-OPEN.
If you make a mistake during the limit programming process press the RESET button on the outside of the control box to
start over.
SINGLE ARM LEFT-HAND SIDE
With the gate in the closed position, press the LEARN LIMITS button. The SET OPEN LIMIT LED will blink.
NOTE: The "Learn Limits" mode can be exited at any time by pressing the RESET button. The mode will time-out
automatically after 60 seconds of inactivity.
