EVENT
None Displayed when all faults have been reset
No power A ground fault has been detected:
For voltage < 1000 V, detection threshold is 166 mA
For voltage >= 1000 V, detection threshold ramps from
166 mA at 1000 V down to approximately 70 mA at
approximately 1500 V.
No power Failed diode(s) in main rectifier
None GF Cutout Switch is open with the system not in REST.
No Propel Temperature exceeds a limit for a sufficient time.
No power Lost communication with both inverters
No power DC link voltage exceeds limit for a sufficient time.
Occurs while not in retard, exceeds propel voltage limit
Occurs while in retard, exceeds retard voltage limit
Occurs instantaneously in propel or retard, exceeds link
voltage limit
Alternator field current exceeds limit.
No power Exceeds current limit over time
Exceeds current limit with no persistence
With persistence due to low engine speed
None Incorrect input from retard lever
None Incorrect input from retard pedal
No power Incorrect link volts
