Codes 3.4 and 3.2 Electromagnetic brake line problems, or electromagnetic brake failure
Use a multimeter to measure the resistance of the two cores on the controller to the plug-in. The specific
operations are as follows:
Code 4.1 Motor or motor line short circuit or controller failure
1. Remove the motor brake disc (the brake line is still connected), connect the motor M1
M2 directly to the positive and negative poles of the battery, observe whether the motor
rotates normally, if not, the motor will fail.
2. If the motor turns normally, the controller should be replaced.
Operation sequence failure in 3.5 and 3.1
1, interlock switch under normal circumstances, use a multimeter to measure the controller
14 core plug-in between J1-6 and the negative pole, when the handle rod is in the switch
working area, there is about 24V voltage. If not, check the interlock switch. For example,
check whether the interlock switch is normal and whether the signal cable of the switch is
connected to the controller.
4.2 Motor voltage cannot match accelerator input, motor or motor ring short circuit and
controller fault, troubleshooting operations are shown as follows:
Normally, it should be
about 40 ω. If no
resistance is displayed,
there is a problem with
the brake line or a short
circuit of the brake coil.
