Fault
code
Description
Cause Check
0215
Low temperature of FR
motor controller
0315
Low temperature of RL
motor controller
0415
Low temperature of RR
motor controller
0016
High temperature of pump
motor controller
1. Controller temperature
over 95℃;
2. Machine overload and
motor mismatch;
3. Controller damage.
1. Check the cooling measures of controller;
2. Monitor the operating current of controller,
re-match the motor if too large, reset the
turning point and slip value，properly
restrict the current if needed.
3. If the above checks fail, replace the
controller.

Severe undervoltage of
pump motor controller
1. Battery data setup
error;
2. Excessive battery
resistance;
3. Damaged fuse;
4. Damaged main
contactor.
1. Measure the battery voltage with a
multimeter to check proper voltage with
KSI and B+ circuits;
2. Check the fuse and contactor;
3. Check the battery setup, system voltage
and undervoltage setting.
4. If the drive controller fails, main contactor
not engaged, the pump controller will
report the fault.

when regenerative
brake enagages.
1. Check the battery with a multimeter for
proper voltage;
2. Check the fuse and contactor;
3. Check the battery setup, system voltage
and undervoltage setting.
4. Check the regenerative brake setup and
current limit.
