PUMP GP-TRANSMISSION 1360529 - Caterpillar

This document provides necessary information for the correct electrical/electronic installation and application of these engines.Engine Functions
Electronic Governing
An electronic governor with a full speed range is used. The electronic governor is isochronous at Low Idle through High Idle or the programmed top engine limit.Fuel to Air Ratio Control (FARC)
The electronic control system has full control of the fuel delivery to the engine. The mechanical Fuel Ratio Control is eliminated. Electronic control of the fuel to air ratio provides optimum performance while limiting emissions.Fuel Injection Timing
Fuel injection timing varies as a function of engine operating conditions to optimize the engine performance. Engine performance is determined by the following conditions:* Cylinder pressure* Emissions* Exhaust temperature* Fuel consumptionShaping of Torque Rise
Electronic controls provide increased flexibility to customize the torque curve over a wide range of engine speeds.Engine Monitoring Feature
The engine monitoring mode determines the level of action that is taken by the Electronic Control Module (ECM) in response to a condition that can damage the engine. These conditions are identified by the ECM from the signals that are produced by the following sensors:* Coolant level sensor* Engine coolant temperature sensor* Engine oil pressure sensor* Inlet air temperature sensor* Transmission pressure sensor* Transmission temperature sensorEngine Monitoring Mode
The engine monitoring mode can be programmed to the following settings:* * DERATE is the factor default setting.ECM Engine Monitoring Programmed to
When the engine monitoring is programmed to , the following parameters are monitored:* Engine coolant level (if enabled)* Engine coolant temperature* Engine oil pressure* Inlet air temperature* Transmission oil pressure* Transmission oil temperatureWhen is selected, the engine will not derate.When an event code is active, the following lamps will be activated:* The diagnostic lamp will flash the flash code.* The alarm for the sensor will come on (if equipped).* The warning lamp will turn on (warning) or flash (derate). Table 1 provides the following information:* The diagnostic event code (EID)* The description of the event code* The status of warning lamp when the diagnostic code is active* The effect of derateTable 1: Engine Monitoring Programmed to ECM Engine Monitoring Programmed to DERATE
If the normal operating conditions are exceeded and the engine monitoring is programmed to DERATE, the ECM will alter the engine performance in steps. The process that reduces the performance of the engine is called "derate."When the engine is derated, the ECM reduces the engine performance in steps until the excessive operating condition is returned to the normal range. The following parameters control the derate process:* The coolant temperature is excessive.* The oil pressure is too low.When the engine monitoring is programmed to DERATE, the following parameters will derate the engine:* Engine coolant level (if enabled)* Engine coolant temperature* Engine oil pressure* Inlet air temperatureWhen the engine is derated, power is derated. Table 2 provides the following information:* the diagnostic event code (EID)* the description of the event code* the condition of the warning lamp when the diagnostic code is active* the effect of derate on the engineTable 2: Engine Monitoring Programmed to DERATE Required
