Default Conditions for the Monitoring System
Table 3 contains the default conditions that cause an event code to be generated. Table 3 also contains a column that describes the system response when the conditions indicate that an abnormal operating condition exists.
Table 3
Default Conditions and System Response
Event Code Conditions which Generate this Code System Response
E004(3) Engine Overspeed Shutdown The engine rpm has exceeded the trip point for engine overspeed for the delay time. The engine will shut down. The code is logged.
E007(2) High Aftercooler Temperature Derate The engine's aftercooler coolant temperature is above the trip point temperature. If the trip point for the derate is exceeded the derate will reduce power linearly from 0% to a maximum of 25% over a period of 480 seconds. The code is logged.
E008(3) High Aftercooler Temperature Shutdown The engine's aftercooler coolant temperature is above the trip point temperature. The engine will shut down. The code is logged.
E009(2) High Altitude Derate The ECM detects atmospheric pressure that is less than 92.5 kPa (13.4 psi). The ECM limits the fuel if the engine is operated above a default altitude that is dependent on the engine rating. The ECM will derate the engine in 3 percent increments for every 305 m (1000 ft) increase in elevation up to a maximum derate of 35 percent. The code is logged.
E015(2) High Engine Coolant Temperature Derate The engine coolant temperature is above the trip point temperature. If the trip point for the derate is exceeded the derate will reduce power linearly from 0% to a maximum of 25% over a period of 480 seconds.
The code is logged.
E016(3) High Engine Coolant Temperature Shutdown The engine coolant temperature is above the trip point temperature. The engine will shut down.
The code is logged.
E017(1) High Engine Coolant Temperature Warning The engine coolant temperature is above the trip point temperature. The code is logged.
E021(2) High Exhaust Temperature Derate The exhaust temperature is above the trip point temperature. The code is logged.
The ramp rate of the derate is 2 percent per 15 seconds.
The maximum derate is 20 percent.
E031(2) Air Filter Restriction Derate The inlet air restriction is above the trip point pressure for the delay time. Derates power 2% per kPa to a maximum derate of 25%. This derate will not reset, if the value falls below the value of the trip point.
The code is logged.
E038(1) Low Engine Coolant Temperature Warning The coolant temperature is below the trip point temperature. The engine must be operated at an average load that is greater than 20% for ten minutes. When the average load is greater than 20% and the coolant temperature is below 80 °C (176 °) for 5 seconds, a warning will occur. To deactivate the warning, the 10 minute average load must drop below 20% or the coolant temperature must be greater than 85 °C (185 °F).
The code is logged.
E040(3) Low Engine Oil Pressure Shutdown The engine
