pump motor controller
Excessively low resistance
of potentiometer.
Overcurrent at potentiometer low end, replace
if necessary
0145
Pot-low overcurrent of FL
motor controller
0245
Pot-low overcurrent of FR
motor controller
0345
Pot-low overcurrent of RL
motor controller
0445
Pot-low overcurrent of RR
motor controller
0046
Invalid EEPROM of pump
motor controller
1. Software error;
2. Controller failure.
1. Download the correct software version;
2. Replace the controller.

0047
Operation sequence error
of pump motor controller
1. Input sequence error of
keyswitch, interlock
switch, directional
switch and accelerator;
2. Failure of keyswitch,
interlock switch,
directional 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 ot check the
accelerator signal;
4. Replace the failed switches.
