1. Connect the barrier gate power supply, press the "▲" and "▼" buttons on the controller to operate the gate arm up and down for 4 to 5 cycles at 90 degrees. If there is a vibration in the gate arm's descent time, it indicates insufficient tension of the balancing spring; move the gate arm 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 with a hex wrench. Ensure the bar reaches the desired effect during the lowering operation.

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

5. If the motor runs but the gate rod does not operate upon lifting, it indicates insufficient tension in the balancing tension spring. Adjust the tension spring status or increase the tension spring until the gate rod operates normally. Jiyang Gate Vehicle License Plate Recognition Rising and Falling Rod.

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

The automatic barrier in the parking lot lowers after 20 seconds of passing through. However, typically, it is triggered by the vehicle's presence. The barrier will only lower when 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 descends. More advanced barrier arms also feature anti-crushing mechanisms, which may be used if the vehicle is small. Needless to say, if the barrier arm is purely manually controlled.
