Fault Condition/Trigger
(For configurable items, fault applies only if
configured. All listed conditions to be met
unless stated otherwise)
UGM has detected an anomaly in EEPROM with regard
to the Machine Setup configuration.
MACHINE SETUP > LOAD SYSTEM ≠ NO;
Load System is the 4-Cell LSS;
and one of the following conditions:
UGM determines LSS-stored values for Unloaded
weight in Indirect 0x100≠ 0x108 or
UGM determines LSS-stored values for Accessory
weight in Indirect 0x102≠ 0x10A
UGM determines LSS-stored checksum1 (0x10F) ≠
checksum 2 (0x107)
Ground software has been installed on a UGM with a
ST10F274 processor (Hardware Rev < 6), which does
not have guaranteed flash storage in the sector where
Constant Data is written.
VLow FET determined to be failed because all Digital
Inputs are high; UGM unable to read high-sensing
inputs.
Load System is the 1-Cell LSS;
Strain Gauge 1 or 2 reports Initialization, Defect or Not
Installed error
(internal error)
The machine will assume the platform is overloaded.
This fault, once annunciated is latched within a given
key cycle.

UGM to prompt operator Power Cycled and EEPROM data in associ-
to correct issue via Ana- ated area is changed
lyzer and disable all
machine and engine func-
tions (i.e., command
engine shutdown and do
not permit start).until
EEPROM data in corrupted
area is changed.

State = Overloaded
Disable all machine and Power Cycled
engine functions (i.e.,
command engine shut-
down and do not permit
start)
Disable all machine and Power Cycled
