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

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

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

4. If the lifting rod exhibits a vibration during operation, it indicates that the tension of the balancing spring is too great. Repeat the following steps (loosen the spring screw to allow the barrier rod to achieve the desired effect during the lowering operation.)

5. If the motor operates during the lifting process but the gate arm does not move, 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. Shanghe Gate Vehicle License Plate Recognition Lift Arm. Automatic Scan Code Barrier Arm.

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

The automatic barrier in the parking lot lowers 20 seconds after the vehicle passes through. However, typically it is sensor-activated. The barrier only lowers after the car has moved on.

The parking barrier arm detects whether a vehicle has passed through the barrier position by using inductive loops in front and behind the arm. After the detection, there is a brief delay before the arm descends. More advanced barrier arms also feature anti-ram mechanisms, which may be used if the vehicle is smaller.
