setup_pot_faults()）
Troubleshooting： Reduce the
throttle pot wiper voltage
42 Throttle Wiper Low
Throttle invalid
1. Throttle pot wiper voltage too low
Reason： Throttle pot wiper(pin
16) voltage is lower than the low
fault threshold(can be changed
with the VCL function
setup_pot_faults()）
Troubleshooting： Raise the
throttle pot wiper voltage
43 Pot 2 Wiper High
Full brake
1. Pot 2 wiper voltage too high Reason：Pot 2 wiper(pin 17)
voltage is higher than the high
fault threshold(can be changed
with the VCL function
setup_pot_faults()）
Troubleshooting：
Reduce the pot
wiper volta
ge
44 Pot2 Wiper Low
Full brake
1. Pot 2 wiper voltage too low. Reason： Pot 2 wiper(pin 17)
voltage is lower than the low fault
threshold(can be changed with
the VCL function
setup_pot_faults()）
Troubleshooting：
Increase the pot
wiper voltage
45 Pot Low Overcurrent
Throttle invalid
Full brake
1. Potentiometer impedance is too
low.
Reason： Pot low end (pin 18)
exceeds 10mA.
Troubleshooting: Reduce low end
current, restart the key switch
46 EEPROM Failure
Motor stops
Main contractor stops.
EM brake stops
Throttle stops
Interlock stops
Driver1-4 stop
PD stops
Brake
Pump stops
1. Error writing to the EEPROM. It
may be caused by VCL writing to
EEPROM, or CANBUS, or
incorrect parameter editing.
Reason：
Controller system tries to
write into EEPROM but failed.
Troubleshooting：Download
correct software(OS), set correct
parameter, and then restart the
key switch.
47 HPD/Sequencing Fault
Throttle invalid
1. Wrong sequence setting of key
start, interlock, direction and
throttle input sequence setting.
2. Wiring, swi
tch key, interlock,
Reason：
The wrong input of key
start, interlock, direction and
throttle cause HPD and
sequencing fault.
