"High Inlet Air Temp Engine Load Setpoint"
The programmable setpoint is a value that separates low engine load from high engine load for events that are activated by high inlet air temperature. An "Engine Load Factor" can be displayed on a Cat ET status screen. When the load factor setpoint is reached and the inlet air temperature increases to the trip point, the following event is activated:
"High Inlet Air Temperature at Low Engine Load"When the load factor setpoint is exceeded and the inlet air temperature increases to the trip point, the following event is activated:
"High Inlet Air Temperature at High Engine Load"Power Monitoring
The ECM monitors the generator output power in order to control the air/fuel ratio. The ECM uses an output from one of the following sources in order to monitor the generator output power:
Electronic Modular Control Panel II+ (EMCP II+)
Programmable Logic Controller (PLC)
WattmeterThe PLC and the wattmeter are also called power sensors.The ECM uses the values of the "Power Monitoring" parameters to estimate the generator actual power output. The ECM estimate of the generator actual power output is displayed on Cat ET as the "Generator Real kW". If the value of this parameter is within one percent of the generator actual power output, the ECM will accurately control the air/fuel ratio."Generator Output Power Sensor Scale Factor"
This parameter is not used for industrial arrangements.If the generator is equipped with the EMCP II+, information on the generator output is provided to the ECM via the Cat data link. The value for the "Generator Output Power Sensor Scale Factor" parameter is correctly programmed at the factory. No further adjustment is necessary for this parameter.If the generator is equipped with a power sensor, the sensor signal increases from 0 to 4.8 VDC as the output increases to the maximum. The maximum output is 110 percent of the generator rated output. For example, if the generator has a rated output of 1700 ekW, the maximum output is 1870 ekW. When the generator output is 1870 ekW, the power sensor will provide a signal of approximately 4.8 VDC.The ECM requires a scale factor in order to estimate the generator output. The equation that is used to determine the scale factor is provided in Table 3.

Computing the Value for the "Generator Output Power Sensor Scale Factor"
(R x 1.1) ÷ 4.8
R is the generatorrated output in kilowatts. For example, if the generator rated output is 1700 ekW, the correct value for the "Generator Output Power Sensor Scale Factor" parameter is 390. In this example, the relationship between the voltage level of the signal and the generator output is shown in Illustration 1 .
Illustration 1 g01062926
In this example, the value of the "Generator Output Power Sensor Scale Factor" parameter is 390.
The ECM multiplies the signal voltage by the scale factor in order to estimate the generator output. In this example, a signal level of 3.5 VDC indicates that the generator output
