GEAR (Idler-10 Teeth) 8S4368 - Caterpillar

Configuration parameters concern various engine features. Some parameters can affect the performance of the engine. Most of the parameters may be programmed with an Electronic Technician (ET) service tool. Some of the parameters require a password in order to be programmed.Note: For information on programming the parameters, use the appropriate ET service tool and see the Service Manual, "Troubleshooting" module.Some parameters may not be available on all applications. If a parameter is not available, the ET service tool will indicate that the parameter is “unavailable” when the parameter is selected. Table 1 is a list of typical configuration parameters.

Engine Rated Speed Software dependent
Air Shutoff (ON/OFF) (If equipped) Programmable
Ether Control (ON/OFF) Programmable
Total Tattletale Unprogrammable
Pilot House EMS Status (ON/OFF) Programmable
Cold Mode Cylinder Cutout Programmable For generator set engines with switchgear conversions and for marine auxiliary engines, the following parameters are programmed at the factory to 0:crank duration and maximum number of crank cycles.
"Crank duration"
"Maximum number of crank cycles"The “0” settings prevent the Electronic Control Module (ECM) from engaging the starting motors. The settings must be reprogrammed before the engine will crank.Engines that are equipped with a generator set control panel do not require reprogramming for "Crank Duration" and for "Maximum Number Of Crank Cycles". These parameters are programmed in the generator set control panel.Ensure that the "Air Shutoff" and the "Ether Control" parameters are "Enabled/ON" (if equipped) . If the engine does not have these options, ensure that these two parameters are "DISABLED/OFF".If the engine is equipped with a prelube pump, the "Engine Prelube Duration" must be programmed to a value that is greater than “0” seconds. Otherwise, the prelube pump will not cycle. If the engine is not equipped with a prelube pump, the parameter must be programmed to “0”.No password is required for programming a new ECM during the first 100 hours of service life. This 100 hour “free configuration” feature enables the customer to tailor the programmable setpoints to the requirements of the installation. Exceptions are the following parameters: "Fuel Limit", "Personality Module Mismatch", "ECM Hours" and "ECM Total Fuel Consumption".Caterpillar Monitoring System
The engine is equipped with a programmable Cat Monitoring System. The ECM monitors the operating parameters of the engine. The ECM can initiate responses if a specific engine parameter exceeds an acceptable range. Three possible responses may be available for each parameter: "", "DERATE" and "SHUTDOWN". Some of the responses are not available for some of the parameters. An ET service tool is used to perform the following activities:
Select the available responses.
Program the level for monitoring.
Program delay times for each response.The settings
