4424 POWER MODULE VOLTAGE TOO LOW - MOD -
ULE SHUTDOWN
None 4_4 • DriveState = PREVENTED
• LiftUpState = PREVENTED
• Severe B+ Undervoltage Set: Capacitor bank voltage dropped
below Severe Undervoltage limit with FET bridge enabled.
• Effect: Reduced Drive Torque
• Possible Cause:
• Battery menu parameters are misadjusted
• Non-controller system drain on battery
• Battery resistance too high
• Battery disconnected while driving
• Blown B+ fuse or main contactor not closed
4475 POWER MODULE - BDI FAULT None 4_4 • DriveState = PREVENTED
• LiftUpState = PREVENTED
• Pump BDI Fault Set: BDI Percentage charge at 0% when the pump
was activated.
• Effect: ShutdownPump
• Possible Cause:
• Battery is fully discharged
• BDI parameters are mis-tuned
4476 BATTERY VOLTAGE TOO HIGH – UNPLUG
CHARGER
None 4_4 • Enter SafeMode
• LiftDownState = MAX
• The Ground Module momentarily measured excessively high battery
voltage (VBAT) (>32.0V) and entered SafeMode to protect system
devices. This may be due to improper battery charging or incorrect
voltage batteries being used.
4477 BATTERY VOLTAGE TOO HIGH – FORCING
DISCHARGE
None 4_4 Lift Down = PREVENTED
Lift Up = PREVENTED
Drive = PREVENTED
• The Ground Module momentarily measured excessively high battery
voltage (VBAT) (>32.0V) and entered SafeMode. This may be due to
improper battery charging or incorrect voltage batteries being used.
