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 4 to 5 times. If the gate arm shows a shaking phenomenon during the lowering process, it indicates that the tension of the balancing spring is insufficient; adjust the gate arm to a vertical position. Automatic vehicle recognition at the Changqing gate, barrier gate lifting arm, and access control vehicle stop arm installation.

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

3. Adjust each tension spring bolt using a hex wrench. Ensure the rod is effectively lowered during 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 procedure (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 that the tension of the balancing spring is insufficient. Adjust the state of the spring or increase the tension until the gate rod operates normally. Shanghe Gate, License Plate Recognition Lift Rod. Automatic Scan QR Code Barrier Gate.

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

The automatic boom in the parking lot will lower 20 seconds after passing through. However, it's usually sensitive. The boom will only lower after the vehicle has passed.

The parking barrier arm uses inductive loops before and after the arm to determine 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-ramming mechanisms, which may be used if the vehicle is smaller. Need I say more about those manually controlled barrier arms?
