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

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 bar reaches the desired effect 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 during the lifting process but the gate rod does not move, it indicates insufficient tension from the balancing tension spring. Adjust the tension spring condition or increase the tension spring until the gate rod operates normally. Jiyang Gate License Plate Recognition Lift Rod. Automatic Scan Bar Code Barrier Gate.

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

The barrier in the parking lot drops 20 seconds after the vehicle passes through. However, typically, it is triggered by the vehicle's movement. The barrier will only lower after the car has passed.

The parking boom barrier detects the vehicle's passage through the barrier by sensing the coils before and after the boom. After the detection, there is a brief delay before the boom descends. More sophisticated boom barriers also feature anti-collision mechanisms, which may be used if the vehicle is small. Need I say more about manually controlled boom barriers?
