16: GATE LIMIT LEARNING PROCEDURE (CONT.)
• If gate closes to right (viewing from secure side), adjust right hand knob of limit assembly (IMAGE
17-5) until the RED LED illuminates on control board (IMAGE 17-4).
10. Press OPEN or CLOSE buttons on the control board till gate is in approximately the halfway position.
11. If dual gate system, unplug the first actuator, plug in the second actuator and repeat Steps 4-9.
12. If dual gate system, plug both actuator motor connectors into Control Board, ensuring that the second
actuator with longer cable is plugged into MOTOR 2 connector.
13. Press OK when "Learn" is displayed to allow operator to begin the learning process.
14. The board automatically begins the limit learning process and the gate(s) moves automatically as follows:
a) A short opening sequence to determine number of motors.
b) A full closing cycle at half-speed to determine close limits (CLOSE LED lights at close position).
c) A full opening cycle at half-speed to determine open limits. (OPEN LED lights at open position).
d) A full closing cycle at full-speed into the closed position. (CLOSE LED lights at close position).
15. The OPEN and CLOSE buttons can now be pressed once (without holding) to fully open and close the
gate(s).
16. Check the position of each gate in its fully closed and open positions before continuing and if gate
limits are acceptable, proceed to next instruction.
NOTES:
By default, there is a 10 second delayed "Auto Close", so after 10 seconds of being open, the gate will
again close. This can be changed and set in the control board options as described in later instructions.
