1. Connect to the barrier gate power supply, press the controller's "▲" and "▼" buttons to operate the gate arm up and down for 4 to 5 cycles at 90 degrees. If the gate arm shows a shaking phenomenon during the lowering, it indicates insufficient tension of the balancing spring; adjust the gate arm to a vertical position. Automatic vehicle identification at the Chqing 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 screw using a hex wrench. Ensure the bar reaches the desired effect during lowering operation.

4. If the lifting rod shakes 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 rod to achieve the desired effect during the lowering operation.) Changqiu Electronic Lifting Rod, License Plate Recognition Barrier Gate Repair, Rising and Falling Rod Wholesales.

5. If the motor operates during the lifting process but the bar does not move, it indicates that the tension of the balancing tension spring is insufficient. Adjust the tension spring status or increase the tension spring until the bar operates normally. Shanghe Gate License Plate Recognition Lift Bar. Automatic Scan Code Barrier Gate Bar.

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

The barrier will descend after 20 seconds of passing through the parking lot, but typically, it's感应activated. It will only lower once the vehicle has passed.

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.
