Engine: C3.3 (S/N: E3J1-UP)Industrial Engine: 3054C (S/N: 3341-UP)Introduction
Reference"General Information"There are two types of Logic Control Governor, the LCG1 and the LCG2.The Caterpillar Logic Control Governor is an electronic governor for speed control which contains a rotary actuator. The circuit board for the controller is in the same housing. The unit can provide a number of preset speeds, bias spring and control settings. The unit also provides the link for the diagnostic and the data functions. This manual covers installation, the programming of software and diagnostics. The functionality of the control unit can be changed with the service tool software.
Do not perform any procedure that is outlined in this publication until you have read the information and understand the information.
Note: Trained personnel should only carry out installation and servicing. By using proper tools, also correct procedures to carry out the installation.Function
Functions that set the speed of the governor are listed below.
Select 50/60 Hz in order to select 1500 rpm or 1800 rpm as the governor speed. This is based on the voltage input when the voltage inputs are applied to the governor.
50/60 Hz can increase engine speed.Raise / lower adjust can decrease engine speed. This is based on voltage inputs while the engine is in operation. The functions of the speed bias are listed below.
The isochronous speed cannot change the speed of the governor. The functions that sense the speed are listed below.
Magnetic Pick Up (MPU) speed sensing converts flywheel speed or the pulse for the ring gear speed into engine speed, in rpm. Control functions are listed below.
The coefficients for the speed control are reset, compensation and gain. The logic and support functions are listed below.
Overspeed error can determine when the actual engine speed is too high.
Underspeed error can determine when the actual engine speed is too low.
Fail safe error. Detect engine speed low of the signal input.
Error on configuration will detect a configuration that has not been downloaded to the controller.
Relay control controls the driver for the relay output during error conditions.
Fault storage. Whenever an error has occurred a fault code is recorded. The fault code is recorded as a Electronic Erasable Programmable Read Only Memory (EEPROM) format.
"Governor state". The generated code by the engine is detected by the governor state: off, crank, start, run, or error. The error is based on code that is generated.Service Software
The LCG1 and LCG2 have a digital control system with no externally accessible adjustment. Software is available in order to help the dealer or the Original Equipment Manufacturer (OEM) with each phase of the application, manufacture and field service. The software for the LCG1 and the LCG2 is compatible with Windows 2000/XP software. The software gives the dealer and the OEM the ability to perform the following procedures:
Input software files to the LCG1 and the LCG2.
Enable the technician to view fault codes .
Enable the Logic control governor software to be updated during the field service.The logic control governor service tools are available from your Caterpillar dealer.Refer to Special Instruction, "Caterpillar Logic
