Fault Condition/Trigger
(For configurable items, fault applies only if
configured. All listed conditions to be met
unless stated otherwise)
The engine is not running
The engine is not cranking
The UGM footswitch input J7-15 is LOW
The machine is in Platform Mode
The Main Dump output J2-13 is detected as HIGH via
the analog feedback 300ms after it is attempted to be
activated during the one time startup test of the UGM
hardware shutoff circuitry
The PM detects that its V(low) FET has failed and
reports this fault to the UGM
The machine is powered up and no model has been
selected yet in the MACHINE SETUP menu
The UGM detects one of the following conditions when
software type is 'P' or 'B':
The Version Verification Word #1 or the Version Verifica-
tion Word #2 values located in the constant data sector
of flash memory (found on constant data spreadsheet
tab pstConstantDataVersion) do not match the values
located in the code area of flash memory
The Version Major value located in the constant data
sector of flash memory (found on constant data
spreadsheet tab pstConstantDataVersion) does not
match the value located in the code area of flash mem-
ory
One or more of the current feedback gains that are cal-
culated and written to flash memory during the PIC
manufacturing test process are detected as being out of
range
The current feedback gains checksum that is calculated
and written to flash memory during the PIC manufac-
turing test process is detected as being incorrect
