Fault
code
Description
Cause Solution
0146
Invalid EEPROM of FL
motor controller
0246
Invalid EEPROM of FR
motor controller
0346
Invalid EEPROM of RL
motor controller
0446
Invalid EEPROM of RR
motor controller
0047
Operation sequence error of
pump motor controller
1. Input sequence error of
key switch, interlock
switch, directional
switch and accelerator;
2. Failure of key switch,
interlock switch, direc-
tional switch and
accelerator;
3. Improper wiring.
1. Check the input sequence of switches to
exclude the operation-induced cause;
2. Use a handhold unit to check each switch
condition;
3. Use a handhold unit to check the accelera-
tor signal;
4. Replace the failed switches.

Setup change of pump
motor controller
The key switch must be
restarted after setup
change of some
parameters.
Restart the key switch to eliminate the fault.

Power supply of pump motor
controller exceeding the
range
1. Excessively high/low
current of external
loads;
2. Check the setup.
1. Check the external loads of 5V and 12V
loading devices for short circuit or
damage;
2. Check the setup (external supply max and
external supply min);
3. Replace the failed devices.
