suction motor and burning the motor.
●During the use of the machine, if there is too much foam, it is recommended to use a
defoamer solution to prevent the foam from entering the filter screen and into the
suction motor, causing the motor to burn.
●Removal of suction motor:
The suction motor is fixed at the bottom of the sewage tank. Before removing:
1. Empty the sewage tank first, turn off the main power switch, and keep the
machine powered off;
2. Turn the sewage tank sideways and pull out the suction motor pair socket;
3. Loosen the fixing nut of the suction motor and take out the suction motor.
●Installation of suction motor:
1. Align the mounting holes of the suction motor with the screw of the sewage tank,
and then tighten it with a non-slip nut.
2. The installation can be completed by plugging the suction motor pair socket with
the machine line.
3.6 Controller function, diagnosis and disassembly
●X5 controller is CM2010C type; fixed inside the machine head, it is a
high-performance permanent magnet brushless motor controller.
●Drive function: Full-bridge power MOSFET control, realizes stepless control of
forward, backward, driving and braking, and realizes soft start and flexible braking.
● Downhill speed limit and anti-backslip function: Do not exceed the maximum
allowable speed when going downhill, and reverse the speed limit when parking on a
slope.
●Brake function: When the brake switch is valid, the vehicle decelerates and brakes
immediately, and finally stops.
●Diagnostic function: You can observe the number of flashes of the panel indicator
lights to determine the corresponding fault cause. For example: when the controller
fails, the control panel indicator will flash 7 times continuously, then pause for 2-3
seconds and then flash 7 times continuously, and so on.
