Code 4.2 Motor Voltage
If the motor voltage can’t match the accelerator input, The motor or motor ring short circuit and controller
failure. Troubleshooting operations as below steps:
Please replace the controller If the voltage of the accelerator changes normally.
Quick determine controller failure.
Pull out the plug of the accelerator. If the controller still reports a fault after power on. Then there is fault
controller
Controller fault light is always on . No walking . Then need to check below step one by one :
1
、
Measure whether there is voltage output 0-5V from the accelerator (Between J1-1 and Negative pole)
2
、
2Short-circuit the J1-6 on the 14-pin plug of the controller with the 7th line on the 5th pin, and turn the
accelerator after restarting the truck to see if there is walking
3
、
The brake locked, Remove the brake (keep the brake cable connected) turn the accelerator after
restarting the truck to see if it is normal
4
、
Remove the brake disc (keep the brake cable connected) Connected The motor M1 and M2 directly to
the positive and negative poles of the battery. And observe whether the motor rotates normally. If not.
The motor Failure
5
、
After all above test finished and all result are normal, then it should be controller problem.
Turn the Multimeter to 24V DC, insert the pin into J1-
1(Accelerator 0-5v speed signal)2(Negative). Turn the
accelerator after Power-on. And observe whether the
Multimeter reading has a linear change of 0-5v voltage
