"Impending Shutdown Delay Enable Status"
Note: This parameter may be "read only" on some applications.This parameter can be programmed to "DISABLED" or "ENABLED". The default is "ENABLED". This parameter determines the control system response to level 2 events.DISABLED - The level 2 event will cause an immediate shutdown.ENABLED - The engine continues to run for the length of time that is programmed for the "Impending Shutdown Delay Time" parameter."Impending Shutdown Delay Time"
This parameter can be programmed to a period of time between "0.1" minutes and "10" minutes. The default value is "10". The engine will shut down after the programmed period of time if a level two event occurs and the "Impending Shutdown Delay Enable Status" parameter is programmed to "ENABLED".Power Monitoring
The ECM monitors the generator output power in order to accurately control the air/fuel ratio. The ECM uses an output from one of the following sources in order to monitor the generator output power:
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 determine the generator actual power output. The electronic control module value of the generator actual power output is displayed on Cat ET as the "Generator Real kW" parameter in "General System Parameters" status group of this parameter is within one percent of the generator actual power output, the ECM will accurately control the air/fuel ratio."Engine Load Input Configuration"
The parameter allows programming the input source for load. The following options are available:
A power sensor that provides an analog signal of 0 to 5 volts
A generator set control via the Cat Data Link"Generator Output Power Sensor Scale Factor"
For power monitoring with a power sensor, the ECM accepts a linear signal with a range of 0 VDC to 4.8 VDC. The signal from the power sensor increases from 0 VDC to 4.8 VDC as the generators output increases. For the best resolution, use as much of the full scale as possible. The kW power sensor should be selected such that the maximum 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 determine the generator output. The scale factor is determined by the full scale range of the power sensors . The equation that is used to determine the scale factor is provided in Table 4.

(R x 1.1) ÷ 4.8
R is the generator rated output in kilowatts.

Power Sensor Maximum Rated Output Voltage 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
