rent feedbacks are out of range at Startup or when
in standby
Applicable Power Module determines at Startup
that there is a problem with overvoltage/under-
voltage detection
not charging properly (increasing voltage) at
Startup
Applicable Power Module determines that an
internal Analog Input error exists
Power Module determines at when traction is
active that the current feedback sensors are out of
the permitted range and may cause incorrect data
acquisition values
Power Module determines at when traction is
active that the current feedback sensors are out of
the permitted range and may cause incorrect data
acquisition values
