Test the limits by pressing the SBC to open and close the gate.
NOTE: If the SET OPEN LIMIT LED is still blinking, the limits were not programmed successfully. Repeat the
programming making sure the gate is fully opened and closed for each respective limit. If the problem persists, refer to the
Troubleshooting section.
PROGRAMMING
Program Limits
The limits are internal settings that indicate when the gates are in the fully open position and the fully closed position. For
proper functionality, the limits must be learned during the installation process. The programmed limit process uses a
combination of buttons on the control board.
The specific buttons used for programming depends on which side of the gates the control box is mounted on and how
many operators the installation includes. Refer to pages 11-12 to determine if the gate is Left- or Right-handed and for
explanation of PULL-TO-OPEN and PUSH-TO-OPEN.
If a mistake is made during the programming process press the RESET button on the outside of the control box to start
over.

automatically after 60 seconds of inactivity.
