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.
NOTES: • If one gate is overlapping the other, the gate that is overlapping must be connected to GATE 1 so it will start moving before the other gate; gate 2 may need to be closed first if there is overlap or a gate lock is being used. • The programming can be exited at any time by pressing the RESET button. Programming times-out automatically after 60 seconds of inactivity.

Diagnostic Chart Your gate operator is programmed with self-diagnostic capabilities. The diagnostic LED will flash a number of times then pause signifying it has found a potential issue. Consult Diagnostic Chart below.
Troubleshooting SYMPTOM POSSIBLE SOLUTION Operator does not run. Diagnostic LED not on. • Power not connected. Make sure the AC/Solar input is connected and that at least one battery is connected with the corresponding fuse intact. • Low or defective battery. Check the battery to make sure that the red wire goes to the positive terminal of the battery and the black wire goes to the negative terminal of the battery. Replace the battery if the open circuit voltage is below 11.5Vdc. • Bad control board.
SYMPTOM POSSIBLE SOLUTION The arm moves but cannot exit Learn Limits mode. Cannot learn limits. • Arm does not extend or contract enough during travel. The arm piston must extend and contract close to its full length to Learn Limits. Adjust the arm mounting so that this can be achieved. • Motor cable wire not connected. Make sure that all the motor wires are connected properly. • Motor housing is not properly seated.
SYMPTOM POSSIBLE SOLUTION Gate opens but does not close. • An open input is continuously activated. Check the open loop or vehicle probe to make sure they are clear of objects. Verify connections and operation for these devices. • Low battery. Measure the voltage across the battery. Voltage should be above 11.5Vdc. Replace battery if required. • (Optional Accessory) Entry system output is connected to the OPEN input, and is “stuck” opening. Verify entry system connections and operations.
