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 programmed during the installation process. The programming uses a combination
of buttons on the control board.
The specifi c buttons used for programming depends on which side of the gate the control box is mounted and how many
operators the installation includes. Refer to pages 11 and 13 to determine if the gate is Left- or Right-handed.
If a mistake is made during programming press the RESET button on the outside of the control box to start over.
