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, 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, Barrier panels, thus affecting operational reliability and mechanical barrier life. The main structure of inverter motor: NdFeB rare earth permanent magnet synchronous motor inverter from coding. The motor speed can be precisely follow the input frequency changes and changes in Jiangsu Barrier, when a significant change was constant torque speed. In power, the situation with the same speed compared to other commonly used motor starting inrush current and volume were minimal, but the torque is 2-3 times that of other motor and when the motor stall for a long time, the electrical current does not work It will rise. Thus lifting the brake lever can be very smooth, electric Barrier, can accurately control the gate (or closing) time consuming, theory accurate to 1/1000 second, and never under any circumstances be damaged motor (not including over Pressure on usage).
