DCU does not get any data from Battery A
DCU does not get any data from Battery B.
Remaining motor operation time < 5 minutes.
Battery voltage difference too high.
NO TAKE-OFF !!!
Battery voltage difference is > 30 V. Battery with lower voltage
is disabled, so no take-off is possible.
Battery Cell Voltage Low
Motor LIMITED !
At least one battery cell voltage gets down to the low level.
If in standby motor operation is demanded but the charger is still
connected.
Motor Current Limit!
Temperature Motor Controller
Motor controller limits power to the motor.
