SETTING MOTOR 1 OPEN/CLOSE LIMITS
After connection of actuator and battery leads to the control board, the gate should now open or
close when the appropriate button(s) on the control box or control board are pressed.
NOTE: For dual gate installations, leave the MOTOR 2 actuator disconnected until after the
MOTOR 1 actuator has been limit adjusted. See INSTRUCTION 13 for MOTOR 2 adjustment
instructions.
1. Remove the cap(s) from the limit screws on the actuator (IMAGE 12-1).

2. Using the appropriate button on the control board, cycle the gate(s) to the open and close
position. If close and open limits are not acceptable, adjust the limit switch in the 816 actuator
as follows:
• Extended actuator: EXTEND more - Turn the EXTEND limit screw counterclockwise
• Extended actuator: EXTEND less - Turn the EXTEND limit screw clockwise
• Retracted actuator: RETRACT more - Turn the RETRACT limit screw clockwise
• Retracted actuator: RETRACT less - Turn the RETRACT limit screw counterclockwise
NOTE: Do not extend extension tube too far out or risk unscrewing tube from main drive
screw. Maximum tube length is 66 inches (167.64 Centimeters).
3. If adjusting a dual gate system, proceed to INSTRUCTION 13.
NOTE:
If gate open/close limit indicators on the control board behave the opposite from what is
expected, reverse the limit lead wiring (orange & wires wires) for that motor.
