391-8170 EMISSIONS ANALYZER TOOL GP - (Bluetooth Module) (1) 1
393-0673 EMISSIONS ANALYZER TOOL GP (1) 1
(1) Either emissions analyzer may be used.
Connect a properly calibrated emissions analyzer to the exhaust stack.
Connect the Caterpillar Electronic Technician (ET) to the service tool connector. Refer to Systems Operation/Testing and Adjusting, "General Information (Electronic Control System)".Note: The engines control system must receive accurate information on the generators power output in order to control the air/fuel ratio.
Verify the information on the generators output power.
If the generator is equipped with an Electronic Modular Control Panel (EMCP), verify that the voltmeter and the ammeter are programmed with the correct values. Refer to the applicable service information for the control panel.
If the generator is equipped with a generator output power sensor (wattmeter), verify that the parameters for the wattmeter are programmed with the correct values. Refer to Systems Operation/Testing and Adjusting, "Electronic Control System Parameters" for information on the "Power Monitoring" parameters.
Verify that the "Fuel Quality" and "Gas Specific Gravity" parameters are programmed correctly. Use the values that are obtained from the Caterpillar Software, LERW4485, "Gas Engine Rating Pro (GERP)".
Verify that the value for the "Fuel Specific Heat Ratio" parameter is correct. Only enter a value of 1.4.
Start the engine. Increase the engine speed to high idle rpm. Verify that the engine is stable.If the engine is unstable, perform the following procedure.
Record the values for these parameters:
"Governor Proportional Gain"
"Governor Integral Gain"
"Governor Derivative Gain"
Set the values for the "Governor Proportional Gain", "Governor Integral Gain", and "Governor Derivative Gain" parameters to zero.
Adjust the "Fuel Quality" parameter until the engine becomes stable and the exhaust oxygen is approximately four percent. Verify that the exhaust port temperatures are below the setpoint for a warning.
Adjust the auxiliary governor. Refer to Systems Operation/Testing and Adjusting, "Engine Governing - Adjust".
Close the main circuit breaker for the generator in order to engage the generator.Note: When the engine load becomes greater than 25 percent, the air/fuel ratio control will operate in the feedback mode.
Slowly ramp the load up to 30 percent.Note: When the air/fuel ratio control is in the feedback mode, the Fuel Correction Factor (FCF) may no longer be 100 percent. The Electronic Control Module may adjust the FCF in order to compensate for the fuel quality and for the ambient conditions.
Set the "Desired Emission Gain Adjustment" parameter to a value of "100".
Verify that the value of the "Generator Real kW" parameter in Status Group 1 is within one percent of the generators output power.If the reading on Cat ET is not within one percent of the generators output power, refer to Troubleshooting, "Generator Output Power Readings Do Not Match".When the value of the "Generator Real kW" parameter is within one percent of the generators output power, continue with this procedure.
