1. Connect to the barrier gate power supply, press the controller's "▲" and "▼" buttons to run the barrier arm up and down 90 degrees for 4 to 5 times. If there is a vibration when the arm lowers, it indicates insufficient tension in the balancing spring; position the barrier arm vertically. Automatic vehicle recognition at the Changqing gate: barrier arm, lift arm, and gate arm installation.

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

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

4. If the lifting rod vibrates during the lifting process, it indicates that the tension of the balancing spring is too great. Repeat the aforementioned operation (loosen the spring bolt to allow the barrier arm to achieve the desired effect during the lowering operation.)

5. If the motor runs but the gate arm does not operate when lifting, it indicates insufficient tension from the balancing tension spring. Adjust the tension spring status or increase the tension spring until the gate arm operates normally. Jiyang Gate License Plate Recognition Rising and Falling Arm. Automatic Scan Code Barrier Arm.

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

The automatic barrier in the parking lot lowers after 20 seconds of passing through, but typically, it is triggered by the vehicle's presence. The barrier will only lower when the car has moved on.

The parking barrier arm detects the vehicle passing through by the inductive loops before and after the arm. After detection, there is a brief delay before the arm descends. More sophisticated barrier arms also feature anti-crushing mechanisms, which may be employed if the vehicle is smaller. Need I say more about the manually controlled barrier arm?
