GASKET 7E7912 - Caterpillar

Application Specific Settings
Note: Although derate may be turned On in the default settings, this application requires all derate to be turned Off when programming the ECM.Derate - Is a reduction of engine horsepower in response to an abnormal operating condition.Setpoint - Is a specific value which can activate the following responses: warning, deration, and shutdown. The setpoint can be a pressure, a speed, a temperature, or a voltage.Hysteresis - Is the change in the signal from a sensor that is tolerated by the ECM. This is the difference between the setpoint that activates a response and the value that deactivates the response. For example, a warning for low voltage can activate if a value below 20 volts is detected by the ECM. The voltage must rise to 22 volts to clear the warning. The hysteresis is the 2 volts that are above the 20 volts.Note: The settings listed below are specific to this application and may differ from the default settings in the software. When replacing an ECM, be sure to program the correct settings for the engine monitoring system.Engine Overspeed
The ECM will automatically perform the following functions if an engine overspeed occurs:
Warning
Shutdown
Table 1
Engine Overspeed
Parameter Default Setting
Warning setpoint 2070 rpm
Warning delay 0 seconds
Shutdown setpoint 2070 rpm
Shutdown delay 0 seconds
Hysteresis 100 rpm
Security level Required password If the engine speed exceeds the setpoint rpm, a warning and a shutdown will occur. The fuel will be shut off and the air shutoff will be activated.
Failure to reset air shutoffs prior to restart may result in severe engine damage.
The air shutoff must be reset before the engine is restarted. Ensure that both of the air shutoffs are reset.High Aftercooler Coolant Temperature
The ECM will automatically perform the following functions when high aftercooler coolant temperature occurs:
Warning
Shut down
Table 2
High Aftercooler Coolant Temperature
Parameter Setting
Warning setpoint 102 °C (216 °F)
Warning delay 5 seconds
Hysteresis 3 °C (5.4 °F)
Security level Required password
Shutdown setpoint 107 °C (225 °F)
Shutdown delay 5 seconds If the aftercooler coolant temperature is above 102 °C (216 °F) for 5 seconds, a warning will occur. To deactivate the warning, the aftercooler coolant temperature must be below 99 °C (210 °F).If the aftercooler coolant temperature is above 107 °C (225 °F) for 5 seconds, a shutdown will occur.High Air Filter Restriction Pressure
The ECM will automatically warn the operator if a high inlet air restriction occurs.The strategy is applied to the right side air filter and/or the left side air filter.

High Air Filter Restriction Pressure
Parameter Default Setting
Warning setpoint 7 kPa (28.1 inch of H2O)
Warning delay 5 seconds
Security level Required password If the inlet air restriction is above 7 kPa (28.1 inch of H2O) for 5 seconds, a warning will occur.High Crankcase Pressure
The ECM will automatically perform the following functions if high crankcase pressure occurs:
Warning
Shut down
Table 4
High Crankcase Pressure
Parameter Setting
Warning setpoint 2 kPa (8 inch of H2O)
Warning delay 3 seconds
Hysteresis −.25 kPa (1.0 inch of H2O)
Security level Required password
Shutdown setpoint 3.5 kPa (14.1 inch of H2O)
Shutdown delay 3 seconds If the
