1. Connect to the barrier gate power supply, press the controller's "▲" and "▼" buttons to make the barrier rod move up and down 90 degrees 4 to 5 times. If the rod shakes during the lowering process, it indicates insufficient tension of the balancing spring; adjust the rod to a vertical position. Automatic vehicle identification barrier arm at the entrance of Changqing. Installation of barrier arm, lifting rod, and vehicle stop arm for access control.

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 rod 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 above steps (loosen the spring screw to allow the barrier arm to achieve the desired effect during the lowering operation.) Changqiu Electronic Lifting Rod, License Plate Recognition Barrier Arm Repair, Rising and Falling Rod Wholesales.

5. If the motor operates but the gate arm does not move upon lifting, it indicates insufficient tension in the balancing tension spring. Adjust the tension spring condition or increase the tension spring until the gate arm operates normally. Jiyang Gate Vehicle Plate Recognition Lift Arm. Automatic Scan Barcode Barrier Arm. Automatic Rise and Fall Arm.

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

The automatic barrier in the parking lot will drop 20 seconds after passing through. However, typically, it is triggered by the vehicle's movement. The barrier will only lower after the car 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 smaller. Needless to say, if the barrier arm is purely manually controlled, it operates without such mechanisms.
