Monitoring System Parameters
The Electronic Control Module (ECM) monitors the operating parameters of the engine. The ECM can initiate a warning or a shutdown if a specific engine parameter exceeds an acceptable range. The default settings for the parameters are programmed at the factory.To accommodate unique applications and sites, many of the parameters may be reprogrammed with the Caterpillar Electronic Technician (ET). The screens of Cat ET provide guidance for the changing of trip points. Use Cat ET to perform the following activities:
Select the available responses.
Program the level for monitoring.
Program delay times for each response.Note: Some of the parameters are protected by factory passwords. Other parameters can be changed with customer passwords."Low Engine Oil Pressure"
The trip point for this parameter is set at the factory. The trip point cannot be changed. If the engine oil pressure is less than the trip point for the engine speed, the ECM will generate a warning or a shutdown. The trip point depends on the engine speed. For example, if the engine is operating at less than 600 rpm and the engine oil pressure is reduced to 175 kPa (25 psi), a warning is generated. If the engine is operating at a minimum of 600 rpm and the engine oil pressure is reduced to 400 kPa (58 psi), a warning is generated. This parameter is always active."Low System Voltage"
If the system voltage reaches the trip point, the ECM will generate a warning or a shutdown. The trip points for the warning and for the shutdown can be programmed with a customer password. This parameter is always active."High Engine Coolant Temperature"
If the engine coolant temperature reaches the trip point, the ECM will generate a warning or a shutdown. The trip point for the warning can be programmed with a customer password. The trip point for the shutdown requires a factory password. The warning can be turned On and Off. The shutdown is always active. The default trip points are dependent on the jacket water coolant temperature rating."Low Engine Coolant Temperature"
If the engine coolant temperature reaches the trip point, the ECM will generate a warning. The trip point for the warning can be programmed with a customer password. This parameter can be turned On and Off."High Jacket Water Pump Outlet Pressure (High Engine Inlet Pressure)"
When the cylinder block inlet pressure increases to the set point, the ECM will generate a shutdown. The trip point for this parameter is set at the factory. The trip point cannot be changed. This parameter is always active."Low Outlet Jacket Water Pressure"
When the engine jacket water pressure decreases to the set point, the ECM will generate a warning. The trip point for this parameter is set at the factory. The trip point cannot be changed. This parameter is always active."Engine Overspeed"
If the engine speed reaches the trip point, the ECM will activate an engine shutdown. A typical trip point is 113 percent of the engine rated speed. The trip point for the shutdown requires a factory password. This parameter is
