Warning Category Indicator System Response Shown on the Cat® Electronic Technician (Cat ET) Service Tool Description of the System Response
(1) "Least Severe" Warning
(3) "Most Severe" Shutdown Use the Cat® Electronic Technician (Cat ET) Service Tool to perform the following activities:
Select the available responses.
Program the level for monitoring.
Program delay times for each response.The default settings for the parameters are programmed at the factory. To accommodate unique applications and sites, the parameters may be reprogrammed with Cat ET. The screens of Cat ET provide guidance for the changing of trip points.Note: Some of the parameters are protected by factory passwords. Other parameters can be changed with customer passwords.Changing the Settings of the Monitoring System
Use the following procedure to change settings of the parameters:
Use Cat ET and select the "Monitoring System" screen.
Highlight the desired parameter. Then click the "Change" button in the lower left corner of the screen.The "Change Monitor System" screen will appear.
Change the "State" to "On" or "Off".
Set the "Trip Point" and the "Delay Time" according to the "Allowed Values" in the lower half of the screen.
Click the "OK" button.If a password is required, the "Enter Passwords" screen will appear. Enter the correct passwords and then click the "OK" button.The new settings will be effective immediately.Monitoring Parameters
"Low System Voltage"
The trip point for this parameter is set at the factory. The trip point cannot be changed. This parameter is always ON. This parameter cannot be turned off. If the system voltage decreases to the trip point or if the system voltage goes below the trip point, the ECM will generate a warning or a shutdown."High Engine Coolant Temperature"
The trip points for this parameter can be programmed by the customer. The shutdown response is always ON. The shutdown response cannot be turned off. If the engine coolant temperature increases to the trip point or if the engine coolant temperature exceeds the trip point, the ECM will generate a warning or a shutdown."Low Engine Coolant Temperature"
The trip point for this parameter can be programmed by the customer. If the engine coolant temperature decreases to the trip point or if the engine coolant temperature goes below the trip point, the ECM will generate a warning."Engine Overspeed"
The trip point for this parameter is set at the factory. This parameter is always ON. This parameter cannot be turned off. If the engine speed increases to the trip point or if the engine speed exceeds the trip point, the ECM will activate an engine shutdown. A typical trip point is 118 percent of the engine rated speed."High Engine Oil Temperature"
The trip point for a warning for this parameter can be programmed by the customer. The trip point for a shutdown is set at the factory. This parameter is always ON. This parameter cannot be turned off. If the engine oil temperature increases to the trip point or if the engine oil temperature exceeds the trip point, the ECM will generate a warning or a shutdown."High Oil Filter Differential Pressure"
The trip point for a warning for this parameter can be programmed by the customer. The trip point for a shutdown is set at the factory. This parameter is always ON. This parameter cannot be turned off. If the engine oil filter differential pressure increases to the trip point or if the engine oil filter differential pressure exceeds the trip point, the ECM will generate a warning or a shutdown."Low Oil Filter Differential Pressure"
The trip point for a warning for this parameter can be programmed by the customer. The trip point for a shutdown for this parameter is set at the factory. This parameter is always ON. This parameter cannot be turned off. If the engine oil filter differential pressure decreases to the trip point or if the engine oil filter differential pressure goes below the trip point, the ECM will generate a warning or a shutdown."High Fuel Temperature"
The trip point for this parameter can be programmed by the customer. If the fuel temperature increases to the trip point or if the fuel temperature exceeds the trip point, the ECM will generate a warning."Low Fuel Pressure"
The trip point for this parameter can be programmed by the customer. If the fuel pressure decreases to the trip point or if the fuel pressure goes below the trip point, the ECM will generate a warning."High Engine Oil to Engine Coolant Differential Temperature"
The trip point for a warning for this parameter can be programmed by the customer. The trip point for a shutdown for this parameter is set at the factory. The shutdown response is always ON. The shutdown response cannot be turned off. If the differential temperature of the jacket water and the engine oil increases to the trip point or if the differential temperature of the jacket water and the engine oil exceeds the trip point, the ECM will generate a warning or a shutdown."Low Gas Fuel Differential Pressure"
The trip point for this parameter can be programmed by the customer. If the fuel differential pressure decreases to the trip point or if the fuel differential pressure goes below the trip point, the ECM will generate a warning."High Gas Fuel Differential Pressure"
The trip point for this parameter can be programmed by the customer. If the fuel differential pressure increases to the trip point or if the fuel differential pressure exceeds the trip point, the ECM will generate a warning."High System Voltage"
The trip point for this parameter is set at the factory. The trip point cannot be changed. This parameter is always ON. This parameter cannot be turned off. If the system voltage increases to the trip point or if the system voltage exceeds the trip point, the ECM will generate a warning.Trip Points of the Engine Load for High Inlet Air Temperature
The trip points for these parameters can be programmed by the customer. The shutdown response is always ON. The shutdown response cannot be turned off. This feature provides a trip point between high engine load and low
