Fault
code
Description
Cause Solution
0221
Declined battery current of
FR motor controller
0321
Declined battery current of
RL motor controller
0421
Declined battery current of
RR motor controller
0022
Reduced over-temperature
performance of pump motor
controller
The controller operates in
hostile environment with
the radiator blade
temperature higher than
85℃
1. Use the machine under normal operating
conditions to increase the cooling effect of
controller.
2. If the ambient temperature is normal,
check the controller current which may
cause an abrupt rise in temperature if
being too high.

Reduced over-temperature
performance of FL motor
controller
0222
Reduced over-temperature
performance of FR motor
controller
0322
Reduced over-temperature
performance of RL motor
controller
0422
Reduced over-temperature
performance of RR motor
controller
0023
Reduced undervoltage
performance of pump motor
controller
1. Low battery level;
2. Battery data setup
error;
3. Battery aging.
1. Check the battery with a multimeter for
proper voltage;
2. Check the fuse and contactor;
3. Check the battery system voltage (pro-
gramme/battery menu nominal voltage)
and (user undervoltage) undervoltage
setting.

Reduced undervoltage
performance of FL motor
controller
0223
Reduced undervoltage
performance of FR motor
controller
0323
Reduced undervoltage
performance of RL motor
controller
0423
Reduced undervoltage
performance of RR motor
controller
0024
Reduced overvoltage
performance of pump motor
controller
1. Battery data setup
error;
2. Regenerative brake
current results in volt-
age rise.
1. Check the battery with a multimeter for
proper voltage;
2. Check the fuse and contactor;
3. Check the battery system voltage (pro-
gramme/battery menu nominal voltage)
and (user undervoltage) undervoltage
setting.
4. Check the regenerative brake current limit
setting (programme/current limits menu re-
gen current limit).
