Fault Condition/Trigger
(For configurable items, fault applies only if
configured. All listed conditions to be met
unless stated otherwise)
MSSO = Active
MACHINE SETUP > LOAD SYSTEM ≠ NO;
Load System is the 4-Cell LSS;
UGM detects LSS report of an anomaly exists that has
caused a WatchDog Timer reset.
MACHINE SETUP > LOAD SYSTEM ≠ NO;
Load System is the 4-Cell LSS;
UGM detects LSS report of an anomaly that exists in the
LSS EEPROM
MACHINE SETUP > LOAD SYSTEM ≠ NO;
Load System is the 4-Cell LSS;
UGM detects LSS report of improper excitation voltage
MACHINE SETUP > LOAD SYSTEM ≠ NO;
Load System is the 4-Cell LSS;
UGM detects LSS report of an anomaly that exists in the
LSS A/D converter operations.
The UGM has detected an anomaly in EEPROM
The UGM software version type is 'P' or 'B'
The UGM has received valid version information from
the PM
The PM software version type is 'P' or 'B'
The UGM software major version number does not
match the major version number of the platform soft-
ware
MACHINE SETUP > LOAD SYSTEM ≠ NO;
Load System is the 4-Cell LSS;
The UGM determines that the LSS software version is
not compatible with existing code.
The tilt sensor gain calibration values recorded to flash
memory during Phoenix International' s manufactur-
ing test are not present
The PM detects that its reference voltage is out of range
and reports the fault to the UGM
