1. Connect the barrier gate power supply, press the controller's "▲" and "▼" buttons to make the gate bar run up and down 90 degrees 4 to 5 times. If the bar shakes during the lowering process, it indicates that the tension of the balancing spring is insufficient; adjust the gate bar to a vertical position.

2. Disconnect the power, open the cabinet, loosen the cover screws, and remove the cover.

3. Adjust each tension spring screw using a hex wrench. Ensure the rod reaches the desired effect during the lowering operation.

4. If the lifting rod shakes during the lifting operation, it indicates that the tension of the balancing spring is too great. Repeat the above procedure (loosen the spring screw to allow the barrier arm to achieve the desired effect during the lowering operation.)

5. If the motor operates but the gate arm does not move during lifting, it indicates insufficient tension in the balancing tension spring. Adjust the tension spring condition or increase the tension spring until the gate arm operates normally. Jiyang Gate Vehicle Plate Recognition Lift Arm. Automatic Scan Barcode Barrier Arm.

How long does it take for the automatic barrier to lower in the parking lot?

The automatic barrier will lower 20 seconds after passing through the parking lot, but typically, it is triggered by the vehicle's movement. The barrier will only lower when the car has passed.

The parking barrier arm uses inductive loops before and after the arm to detect if a vehicle has passed the barrier position. After detection, there is a brief delay before the arm descends. More advanced barrier arms also feature anti-crushing mechanisms, which may be used for smaller vehicles. Need I say more about those purely manually controlled barrier arms?
