Severe Undervoltage
Reduced drive torque.
1. Battery Menu parameters are
misadjusted.
2. Non-controller system drain
on battery.
3. Battery resistance too high.
4. Battery disconnected while
driving.
5. See Monitor menu

Battery:
Capacitor Voltage.
6. Blown B+ fuse or main
contactor did not close.
Set:
Capacitor bank voltage
dropped below the Severe
Undervoltage limit with FET
bridge enabled.
Clear:
Bring capacitor voltage
above Severe Undervoltage
limit.

Battery:
Capacitor Voltage.
2. Battery Menu parameters are
misadjusted.
3. Battery resistance too high
for given regen current.
4. Battery disconnected while
regen braking.
Set:
Capacitor bank voltage
exceeded the Severe
Overvoltage limit with FET
bridge enabled.
Clear:
Bring capacitor voltage
below Severe Overvoltage limit,
and then cycle KSI.
22
Controller Overtemp Cutback
Reduced drive and brake torque.
1.
See Monitor menu»
Controller: Temperature
2. Controller is performance
limited at this temperature.
3. Controller is operating in an
extreme environment.
4. Excessive load on vehicle.
5. Improper mounting of
controller.
Set:
Heatsink temperature
exceeded 85°C (185°F).
Clear:
Bring heatsink
temperature
below 85°C (185°F).
23
Undervoltage Cutback
Reduced drive torque.
1. Normal operation. Fault
shows that the batteries need
recharging. Controller is
performance limited at this
voltage.
2. Battery parameters are
misadjusted.
3. Non-controller system drain
on battery.
4. Battery resistance too high.
5. Battery disconnected while
driving.
6. See Monitor menu» Battery:
Capacitor Voltage.
7. Blown B+ fuse or main
contactor did not close.
Set:
Capacitor bank voltage
dropped below the Undervoltage
limit with FET bridge enabled.
Clear:
Bring capacitor voltage
above Undervoltage limit.
