Operational limitations in failure situations
Operational limitations are applied to the engine when alarms or failures shown in Table 2-19 occur. These
limitations can be changed depending on properties of the machine to which the engine is installed.
Table 2-18 shows mapping flags to be used for limiting the engine operation.
Table 2-19 shows alarms and failures at which operational limitations are applied to the engine, and flags for
the limitations.
