First, the gate of the hinge screw loose: joint screw for the positive and negative thread phase, up and down between the two bearings with double-headed screw phase, if the screw loose, will cause the upper and lower bits are not accurate. Use a 80MM long Ф4 iron rod inserted between the double-headed screw to adjust the brake lever up and down in place. Second, the road gate embedding loosening: When the local sense of the coil can not be firmly fixed in the nest, the car crushed the road vibration will cause the nest within the coil deformation, changing the initial sense of inductance, then the sensor must be reset before normal work. The solution is to pour melted bitumen to fix it. Third, the gate of the crank arm screws loose: If this screw loose, will result in the track gate bar is not accurate up and down the bar and shake the larger, the bolt hanging tight, the nut can be locked. Fourth, the power protection switch off: When the control part of the gate failure, the road gate automatic protection device will automatically work at this time the brake lever stopped at a diagonal position does not move, the total power off, the machine does not work. At this point the machine door is opened, the large belt clockwise to rotate 3-8 laps to the upper position can be restored. If so many times can not restore the status quo, you need to check the Hall components and circuit board failure. Suzhou shutter repair! Fifth, place the control magnet in place: up and down are used Cimin Hall components, if the rectangular magnet and reducer with a cam disc position change, resulting in inaccurate place. Adjust it accurately, can not flip, you can solve the problem. Sixth, the pull-down hook adjustment nut loose: The lower part of the chassis with thread M10 pull-down hook, its function is to pull the balance mechanism of the spring and balance function zero adjustment. And equipped with two M10 hex nuts and Ф10 spring washers, if the nut is loose, the percussion sound and balance imbalance occurs when the machine is running, although the machine can run after the balance imbalance, but will greatly increase the reducer, motor and other drive The load on the machine affects the reliability and mechanical life of the gate.
