The coil of the barrier is loose: when the local induction coil cannot be firmly fixed in the nest, the vibration of the car over the road will cause the deformation of the coil in the nest and change the initial inductance of the ground inductance. At this time, the sensor must be reset before it can work normally. . The solution is to pour melted asphalt into it to fix it.

Common faults and maintenance methods of Gate are mainly as follows:


The coil of the barrier is loose: when the local induction coil cannot be firmly fixed in the nest, the vibration of the car over the road will cause the deformation of the coil in the nest and change the initial inductance of the ground inductance. At this time, the sensor must be reset before it can work normally. . The solution is to pour melted asphalt into it to fix it.
 
The joint screws of the barrier are loose: the joint screws are connected by positive and negative threads, and the upper and lower bearings are connected by a double-ended screw. If the screws are loose, the upper and lower positions will be inaccurate. Insert an 80MM long Ф4 iron rod between the double-headed screws and turn the adjustment gate rod up and down.
 
The turning arm screw of the barrier is loose: If this screw is loose, it will cause the barrier of the barrier to be inaccurately up and down and to shake when the bar is stopped. Just suspend the bolt and lock the nut.
 
In-position control magnet shifting: The upper and lower in-position adopts Cmin Hall elements. If the position of the rectangular magnet and the cam disc of the reducer is changed, the in-position may be inaccurate. The problem can be solved by adjusting it accurately and not turning it over.
 
Power-off protection switch: When the control part of the barrier fails, the automatic protection device of the barrier will automatically work. At this time, the barrier rod stops at the inclined up position and does not move, the main power supply is disconnected, and the machine does not work. At this time, open the door of the machine, and turn the large belt clockwise 3-8 times to the upper position to recover. If the original state cannot be restored for so many times, it is necessary to check whether the Hall element and the circuit board are malfunctioning.
 
The adjustment nut of the pull-down hook is loose: there is a threaded M10 pull-down hook in the lower part of the chassis, and its function is to pull the spring of the balance mechanism and adjust the zero point of the balance function. It is also equipped with two M10 hexagon nuts and Ф10 spring washers. If the nuts are loose, knocking noises and imbalance will occur when the machine is running. Although the machine can still run after the imbalance, it will greatly aggravate the reducer, motor and other transmissions. The load of the mechanical parts affects the reliability and mechanical life of the barrier gate operation.
