There are many possibilities for the mall to fail. we are here Jinke Dacheng's technical engineers lists the common failure reasons of swing gate in shopping malls, and analyzes in detail the swing arm after the power swing gate swing back and forth or open the situation of channel gate.

Determine whether the limit photoelectric switch is illuminated by strong light and cover the box. If you need to open the box or box cover, please use an opaque dark object to cover the upper limit photoelectric switch for debugging.

Detect the photoelectric limit switch a, check whether the zero, left and right limit photoelectric switch is energized, check whether the wire is loose and poor contact; Enter the debugging menu, turn the brake shaft to drive the hood to cut off the optical coupler of left, zero and right limit photoelectric switch successively

Swing gate 523.

Check whether the limit photoelectric switch is reliably connected to the main board

If the limit photoelectric switch and cable are normal, the motherboard will be damaged.

After the swing brake is effectively opened, the brake does not move

Indicators on the mainboard are normal. When the switch signal is sent, the indicator blinks intermittently and the direction indicator turns green. Check the output voltage of PC and PD at PX terminal, and check whether the fuse is broken. When it is normal, check whether there is voltage output at MA and MB terminals of PX terminal; when there is output, check whether the motor connection is welded; Whether the motor is damaged

The main board indicator light is not on, and the LED digital tube is not displayed. Test the voltage output of PA and PB at PX terminal, and test the fuse of the fuse.

If the above conditions are normal, determine whether the mainboard is damaged.
