Configuration parameters concern various engine features. Some parameters can affect the performance of the engine. Most of the parameters may be programmed with a Caterpillar 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 Cat 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 Cat ET service tool will indicate that the parameter is “unavailable” when the parameter is selected.
Table 1 is a list of typical configuration parameters.
| Typical Configuration Parameters | |
|---|---|
| Parameter | Programmability |
| Air shutoff (ON/OFF) | Yes |
| Crank duration | Yes |
| Crank terminate speed | Yes |
| ECM serial number | No |
| Engine rated speed | Software dependent |
| Engine serial number | Yes |
| Equipment ID | Yes |
| Fuel correction factor | Yes |
| Low idle speed | Yes |
| Maximum number of crank cycles | Yes |
| Personality Module Part Number | Software dependent |
| Personality module release date | Software dependent |
| Rated fuel position | Yes |
| Total fuel | Yes |
| Total hours | Yes |
| Total tattletale | No |
The Emergency Diesel Generator set (EDG) is delivered for installation with a crank duration of 10 seconds.
Ensure that the "Air Shutoff" parameter is "Enabled/ON".
No password is required for programming a new Electronic Control Module (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 "Fuel Limit" and "Personality Module Mismatch".
The air shutoff uses a plate that rotates on a shaft in order to shut off inlet air to the aftercooler. The engine stops because of the restricted air supply to the combustion chamber. The air shutoff only actuates for the following conditions:
- The Emergency Stop button is pressed.
- An overspeed shutdown occurs.
- The operator manually activates the air shutoff with the emergency air shutoffs on the engine. It is not necessary to activate both of the air shutoffs in order to shut down the engine. If one air shutoff is activated, the other air shutoff is activated automatically.
Both of the air shutoffs must be reset before the engine can be restarted.

To reset the air shutoff, turn the reset knob to the "OPEN" position.
Ensure that both of the air shutoffs are reset.
When the engine is shipped from the factory, an estimate of the engine's fuel consumption is programmed into the ECM. The estimate is based upon the engine's performance specifications. The actual fuel consumption can be determined with a meter that measures the flow of the fuel. Customers are likely to find a slight difference between the estimate of fuel consumption that was programmed and the actual fuel consumption. The customer can use a Cat ET service tool to program the ECM for the actual fuel consumption. A factory level security password is required in order to change this parameter.
To program the ECM for the actual fuel consumption, change the Fuel Correction Factor that is already programmed into the ECM. The Fuel Correction Factor can be programmed in increments of 0.5 percent between ± 25 percent.
The Cat ET service tool can display the trends of the engine performance. The information can be used to improve the overall performance of the engine. The historical information is stored in a format that can be used to construct histograms. Data is available for the following parameters:
- Engine rpm
- Percent of engine load
Incrementing the Hours of the ECM
A new ECM that is installed on an engine can be programmed to display the correct total number of operating hours for that engine. A Cat ET service tool and a factory level security password are required.
Adjusting the Total Fuel Consumption for the ECM
A new ECM that is installed on an engine can be programmed to display the correct total fuel consumption for that engine. A Cat ET service tool and a factory level security password are required.
The CAT Data Link provides the ability for the diesel generator control panel (DGCP) to monitor various engine parameters. The communication is established through the engine vision interface module (EVIM).

The CAT Data Link Flash provides the capability to flash the software for the engine control with the CAT Data Link.
