Event Code
Description Conditions which Activate the Code System Response
E243(1) High Left Turbo Turbine Outlet Temperature The temperature at the outlet for the left turbocharger turbine has exceeded the trip point and the delay time has expired. The alarm output is activated. The code is logged.
E243(3) High Left Turbo Turbine Outlet Temperature The shutdown output is activated. The code is logged. The engine is shut down.
E244(1) High Right Turbo Turbine Outlet Temperature The temperature at the outlet for the right turbocharger turbine has exceeded the trip point and the delay time has expired. The alarm output is activated. The code is logged.
E244(3) High Right Turbo Turbine Outlet Temperature The shutdown output is activated. The code is logged. The engine is shut down.
E245(1) High Right Turbo Turbine Inlet Temperature The temperature at the inlet for the right turbocharger turbine has exceeded the trip point and the delay time has expired. The alarm output is activated. The code is logged.
E245(3) High Right Turbo Turbine Inlet Temperature The fuel is shut off. The shutdown output is activated. The code is logged. The engine is shut down.
E246(1) High Left Turbo Turbine Inlet Temperature The temperature at the inlet for the left turbocharger turbine has exceeded the trip point and the delay time has expired. The alarm output is activated. The code is logged.
E246(3) High Left Turbo Turbine Inlet Temperature The fuel is shut off. The shutdown output is activated. The code is logged. The engine is shut down. Probable Causes
Low load
Excessive load
High inlet manifold temperature
Incorrect air/fuel ratio
Exhaust restriction
Problem with a valveRecommended Repairs
Low Load
At loads that are less than 50 percent, the inlet air is controlled by the air choke actuator. If the air/fuel mixture is too lean, compression of the higher volume of air through the turbocharger will increase the temperature. Correct the air/fuel ratio.Excessive Load
Make sure that the load is not excessive. Reduce the load. If necessary, disengage the driven equipment and test the engine.Check for Event Codes for High Inlet Manifold Air Temperature
Use the control panel's display to check for the following event codes:
E026 (3) High Inlet Air Temperature (shutdown)
E027 (1) High Inlet Air Temperature (warning)If one or more of the codes is active, refer to Troubleshooting, "Inlet Air Temperature Is High".Air/Fuel Ratio
An air/fuel mixture that is too rich will increase the exhaust temperature. A change in the fuel energy content will change the air/fuel ratio. Obtain a fuel analysis.The fuel supply pressure must be adequate and stable. Adjust the engine according to Systems Operation/Testing and Adjusting, "BTU and Precombustion Chamber Adjustments".Verify that the exhaust emissions are correct.Measure the Exhaust Restriction
Measure the exhaust restriction during engine operation with a load. For data that is specific to the engine, refer to the Technical Marketing Information. Also refer to the Application and Installation Guide, LEBW4970, "Exhaust Systems".Investigate the cause of the exhaust restriction. Perform adjustments and/or make repairs, as needed.Problem with a Valve
Make sure that the inlet valves, the exhaust valves, and the gas admission valves are in good condition. Check the cylinder compression. Refer to Operation and Maintenance Manual, "Cylinder Pressure - Measure/Record".
