8. To verify that the operator recognizes the target magnet, turn off both DC and AC power switches and
watch the display go blank. Then, turn both switches on. The operator beeps indicating Limit Relearn
Mode. The gate then travels about 6 inches (15cm) in the open direction and stops. The buzzer beeps
again and the gate travels in the close direction at a rate of .5 ft/s until the target magnet passes the target
sensor. The buzzer sounds one last time, the operator resets, and “GATE CLOSED” appears on the
display.
9. If “LEARN OPEN” appears, then the target magnet was not detected. Check chain alignment and make
sure the target magnet passes across the face of the sensor. See Figure 1-14.
Note: Repeat steps 6 – 8 if you are still having difficulty with the operator learning its limits.
