Monitoring Parameters
"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's rated speed for generator set applications."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, a derating, or a shutdown."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 Inlet Air Temperature at High Engine Load"
The "Service/Configuration" screen of Cat ET defines the "High Inlet Air Temp Engine Load Set Point". The ECM can activate a warning, a derating, or a shutdown if the inlet air temperature increases to the trip point or if the inlet air temperature exceeds the trip point during the high load operation that is defined."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."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 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."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 Fuel Pressure"
The trip point for this parameter can be programmed by the customer. The ECM will activate a warning if the fuel pressure increases to the trip point or if the fuel pressure exceeds the trip point."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 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."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."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 Differential Fuel 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 Differential Fuel 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.Conditions for Parameters
Some of the programmable parameters are dependent on the status of an ECM output before the parameters are allowed to function. Some of the parameters are allowed to function after the crank terminate relay has been energized for more than 30 seconds. Other parameters are allowed to function after the output for the fuel control relay is energized. Some parameters are not dependent upon any conditions.The conditions are designed to eliminate false events during start-up if the customer has programmed a delay time to zero.If the trip point for a shutdown is programmed to activate before the trip point for a warning, the engine will shut down and the warning will not be activated.
