Systems Description
Original

This feature is capable of storing 100 exceedance Logs. Exceedances
are recorded for EGT, engine torque, transmission torque, N
G
, N
P
, N
R
(high), engine oil pressure (low), transmission oil pressure (low), and
cargo hook.
Exceedance logs maybe either recorded or downloaded to the GBMC.
Perform Exceedance Log Menu procedure (Ref. Figure 7−40) to access
cumulative usage data.
The Fault Log contains data associated with fault discrete data from
the EEC’s and a BIT failure that was detected in the IIDS, BMS, or
aircraft transducers/sensors. This type of log is recorded whenever an
IIDS, EEC, or aircraft sensor fault is detected. The system is capable
of storing 100 Fault Logs.
Fault logs maybe either recorded or downloaded to the GBMC.
Perform the Fault Log Menu procedure to access data (Ref. Figure 7−42).
IIDS setup contains (Ref. Figure 7−43) data that reflects the current
configuration of the aircraft, such as, aircraft serial number, engine
type installed, engine serial number, fuel calibration, operating soft
ware, etc.
On power up, the IIDS uses information in the setup log to compare
the current Torque and EGT trim values from the EEC to the values
stored in the IIDS setup log to assure the data collected by the IIDS
remains with the respective engine. If there is a discrepancy, a fault
log is created and certain engine ASCM functions are disabled for the
affected engine(s): Exceedance Logs for N
G
, N
P
, Torque, EGT; Power
Assurance function (including trend logs); and Cumulative Logs (cycle
counting, SSO, FSO, TSN, and engine run time).
To recover from this disable function, the Setup Log must be revised
to match the values from that specific engine(s) through the GBMC.
Once the Setup Log has been revised, a power−up of the IIDS will verify
the new data. If the new values match, all engine ASCM functions are
restored.
The IIDS features 7 keys on the right side of the front face to allow
the pilot access to the various functions/programs by paging through
the menus. The keys include:
‘‘CLR’’ (clear): Used to blank the alphanumeric display and exit all
menu functions if pressed for more than 1.5 seconds. If pressed for less
than 1.5 seconds in the Night Mode after a C/W/A event, the CLR key
resets the intensity to the previous setting.
