Barrier common faults and repair methods are as follows: place the control magnet move bits: up and down in place are used chee Hall-element, if the rectangular magnet and gear change with the position of the cam disc, resulting in inaccuracies in place. Be adjusted accurately, non-reversible, can solve the problem. By hooking the adjusting nut loose: the lower part of the chassis has a lower threaded M10 retractors, residential Barrier, its function is to pull zero adjustment spring balancing mechanism and balancing functions. And is equipped with two M10 hex nuts and spring washers Ф10, if this nut loose, knocking sound and balance disorders occur when the machine is running, although the imbalance after the machine can also work, but it will greatly increase the speed reducer, motor and other drive mechanical load, thus affecting operational reliability and mechanical barrier life. Barrier common faults and repair methods are as follows: The crank arm loose screws Barrier: If this screw loose, Barrier principle, will result in a larger rock bit inaccurate and stop lever under the barrier gate rod bolts hanging tight lock nut. Power protection switch off: When the failure of the control section Barrier, Barrier brand, automatic protection barrier will work automatically, Shenyang Barrier, then parked on the ramp brake lever position does not move, the total power supply is disconnected, the machine is not working. The machine door is opened, the large belt rotates clockwise circle 3-8 when the host can be restored. If so many of restitution, you need to check whether the Hall element and a circuit board malfunction.
