1. Connect to the barrier gate power supply, press the "▲" and "▼" buttons on the controller to run the barrier arm up and down for 4 to 5 cycles at 90 degrees. If the arm shows a shaking phenomenon during the lowering, it indicates insufficient tension in the balancing spring; adjust the barrier arm to a vertical position. Automatic vehicle recognition at the Changqing gate: barrier arm, gate arm, and vehicle stop arm installation.
2. Disconnect the power source, open the cabinet, loosen the cover screws, and remove the cover.
3. Adjust each tension spring screw using a hex wrench. Ensure the rod is effective during the lowering operation.
4. If the lifting rod vibrates during the lifting operation, it indicates that the tension of the balancing spring is too great. Repeat the aforementioned steps (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 bar does not move upon lifting, it indicates insufficient tension in the balance tension spring. Adjust the tension spring condition or increase the tension spring until the bar operates normally. Jiyang Gate License Plate Recognition Lift Bar. Automatic Scan QR Code Barrier Gate.

How long does the automatic boom arm take to lower at the parking lot?
The automatic boom at the parking lot will lower after 20 seconds of passage. However, typically, it is triggered by the vehicle passing by. The boom will only lower after the car has moved on.
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 lowers. More advanced barrier arms also feature anti-crushing mechanisms, which may be used if the vehicle is smaller. Need I say more about those purely manually controlled barrier arms?
