14.2.5 High NRS Temperature
14.2.5.1 High NRS Temperature Operation
The engine control system monitors the NRS gas temperature in order to
prevent the temperature exceeding allowable levels. This monitoring system
parameter is required to prevent component damage due to excessive NRS
temps. The High NRS temperature protection supports Severity L1 and
Severity L2 only. When an L2 event is triggered the engine will initiate a
derate as shown in table 14.13. The associated diagnostics are shown below.
