Component description Function check with diagnosis instrument Limp home values (emergency control values) The basic values are used by the control unit to allow the engine to keep going if there is a technical fault in the system or its auxiliary equipment, sensors etc. Menus with sub-menus Engine speed (rpm) Engine speed Nominal engine speed The following values (Limp home values) are stored in the control unit: Control rod Control rod travel (mm) Relative control travel (%) Fuel temperature .......................................... 40 ° C Charge air temperature ................................. 55 ° C Coolant temperature .....................................
10 ° C Absolute pressure (kPa) Temperatures Charge air pressure .................. Please refer to the diagram on the previous page Coolant (°C) Fuel (°C) Charge air (°C) Engine speed ..........................................1000 rpm Fuel consumption nputs/Outputs (Please refer to explanation on next page) In 00000000 00000000 Out 00000000 00000000 Extreme values Highest and lowest values, and the time that an ex- treme value has been exceeded are stored in the con- trol unit.
These values can be read by means of a diag- nosis program (please refer to the “Function check with diagnostic program“ chapter) Engine history Operation time (hours:min:sec) The following extreme values are pre-programmed into the control unit: Basic data VShows engine specifications, engine number, “data set“ (parameter file) part number, time when it was installed and where, and by whom, it was programmed. Low charge air temperature ............................ 0° C Charge air temperature ................................ 110° C High fuel temperature ....................................60° C Low fuel temperature ......................................
