PUMP GP-PISTON 6E5280 - Caterpillar

System Configuration Parameters are parameters that affect emissions, power of the engine, and other features. The parameters are programmed at the factory. In most cases, the parameters do not need to be changed. The System Configuration Parameters must be reprogrammed if an Electronic Control Module (ECM) is replaced and/or the engine rating is reprogrammed. System Configuration Parameters do not need to be reprogrammed if the Personality Module is replaced. Proper values for these parameters are available on the Caterpillar Electronic Technician (ET). Certain Configuration Parameters are also stamped on the Engine Information Plate.Note: If the parameters that are protected with the factory passwords are changed, the Caterpillar warranty may be voided.
Engine Serial Number
The engine serial number should be programmed to match the engine information plate. The serial number is not programmed on a new ECM.Fuel Ratio Control (FRC) Offset
The ECM determines a value that is based on the atmospheric pressure. The value is used to adjust the fuel ratio control. This will control the exhaust while the engine accelerates. An offset value of 25 may be used to adjust for customer preference, fuel quality or other factors that affect engine performance.Note: This parameter may not be available on all applications.Rated Fuel Position
This parameter is used to set engine power. A Factory Password is required to change this setting.
Table 1
Minimum Default Maximum
Minimum Rack Engine Dependent Engine Dependent Low Idle
The parameter defines the lowest rpm level.
Table 2
Minimum Default Maximum
300 rpm 600 rpm 900 rpm Cooldown Speed
This parameter defines the engine rpm level when the Engine Control Switch (ECS) is placed in the STOP position.
Table 3
Minimum Default Maximum
300 rpm 600 rpm 1600 rpm Cooldown Period
This parameter defines engine operation at the cooldown speed. Programming this parameter to 0 will disable this function.
Table 4
Minimum Default Maximum
0 minutes 5 minutes 30 minutes Prelube Time
This parameter sets the engine prelubrication timeout period. Programming this parameter to 0 will disable this function.
Table 5
Minimum Default Maximum
0 seconds 0 seconds 210 seconds Crank Duration
The crank duration determines when the starting motors will be energized. The crank duration determines when the starting motors will be disengaged. Programming this parameter to 0 will prevent the ECM from engaging the starting motors.
Table 6
Minimum Default Maximum
0 seconds 0 seconds 60 seconds Cranking Cycles
This parameter is the total number of crank cycles that can be performed.
Table 7
Minimum Default Maximum
0 0 10 Crank Terminate Speed
This parameter determines when the starting motor will disengage.
Table 8
Minimum Default Maximum
100 rpm 400 rpm 500 rpm Air Shutoff
Programming the parameter to "OFF" will disable the air shutoff. This parameter should be programmed to "OFF" if the function is not being used or installed on this engine. This will prevent diagnostics from being logged.Note: This parameter can only be read from the secondary ECM.
