FILTER ELEMENT-FUEL 7W8910 - Caterpillar

Use this procedure in order to troubleshoot an engine overload condition. Also use this procedure if the following event code is active.
Table 1
Event Code
Description Conditions which Activate the Code System Response
E242 (2) Engine Overload The engine load has exceeded the trip point and the delay time has expired. The alarm output is activated. The code is logged. Probable Causes
Excessive inlet manifold air pressure
The Low Heat Value (LHV) of the gas or the specific gravity of the gas is significantly different from the value that is programmed.Recommended Repairs
Check the Inlet Manifold Air Pressure
The calculated engine load increases when the air inlet pressure increases. Measure the air inlet pressure during engine operation with a load. For specific data on the engine, refer to the engine Technical Marketing Information.Obtain a Fuel Analysis and Program the Fuel Energy Content
Obtain an analysis of the gas in order to determine the LHV. Program the correct LHV for the "Fuel Quality" configuration parameter.If the LHV of the gas does not match the "Fuel Quality" parameter value that is programmed into the Electronic Control Module (ECM), program the ECM with the correct value for the "Fuel Quality" parameter by selecting the "Change" button in the lower left corner of the screen. Type the correct value and then select "OK".If the quality of the gas is not consistent, obtain several analyses over a period of time. Program the "Fuel Quality" configuration parameter to the average value of the LHV.
