Description
40
GPS reconnection error: Check connection status
41
Release unlocking instruction through platform (only applicable to the ECU with the GPS function)
42
Platform left turn button pressing error during start: Ensure that buttons on the handle are not pressed. If
not, consider replacing the handle or the PCU.
43
Platform right turn button pressing error during start: Ensure that buttons on the handle are not pressed. If
not, consider replacing the handle or the PCU.
46
Platform handle enable switch button pressing error during start: Ensure that the enable switch on the
handle is not pressed. If not, consider replacing the handle or the PCU.
47
“The platform handle is not in the middle position” error during start: Confirm that the handle is in the
middle position, and check the middle position parameter setting. If normal, consider replacing the handle or
the PCU.
52
Forward coil error: Check the connection of the coil and confirm that it is normal. If normal, check the coil for
short circuit or open circuit.
53
Backward coil error: Check the connection of the coil and confirm that it is normal. If normal, check the coil
for short circuit or open circuit.
54
Lifting error of lifting coil: Check the connection of the coil and confirm that it is normal. If normal, check the
coil for short circuit or open circuit.
55
Lifting error of lowering coil: Check the connection of the coil and confirm that it is normal. If normal, check
the coil for short circuit or open circuit.
56
Right turn coil error: Check the connection of the coil and confirm that it is normal. If normal, check the coil
for short circuit or open circuit.
57
Left turn coil error: Check the connection of the coil and confirm that it is normal. If normal, check the coil for
short circuit or open circuit.
58
Brake coil error: Check the connection of the coil and confirm that it is normal. If normal, check the coil for
short circuit or open circuit.
60
Check the motor controller.
61
Cool down the machine, and check the wiring. If the wiring is OK, replace the motor controller
62
Restart the machine, if fault exists, check the root cause; if fault still exists, replace the motor controller
63
Check the wiring, and then restart it, and replace the motor controller if necessary
64
Check whether the motor parameter enable delay is too short, and confirm that the parameter is correct
65
Check the wiring, and ensure that the correct throttle type is selected in the motor controller
66
Ensure that the emergency reverse check parameter in the motor controller is set to off
67
The motor enable delay may be too short, and confirm that parameter of other motor controllers is correct
68
Low voltage error: Check the battery voltage and charge if necessary. Check connection between the
battery and the switch, reinforce or clean it. Check whether the voltage of the PCU and the ECU is normal.
69
MC is detecting current in the motor, but there shall be no current in this case. MC thinks that the brake is
turned on
70
Adjust the ZAPI and/or check the toggle voltage due to loose wiring
71
Check wiring of main contactor, replace contactor if necessary, or replace motor controller
72
Check the battery voltage, check if it is charging. If the fault still exists, try to replace the motor controller
73
Cool down the restart machine or replace the motor controller
