Engine Monitoring Parameters

Usage:

C13 EMS

"Engine Monitoring Mode"

This parameter determines the level of action that will be taken by the Engine Control Module (ECM) in response to a condition that has the capability to damage the engine. The ECM reads the coolant temperature, oil pressure, and intake manifold air temperature. If the ECM has been programmed to monitor the OEM installed coolant level sensor, the ECM will read that sensor.

"Engine Monitoring Lamps"

This parameter determines the lamp requirements for the engine monitoring system. If this parameter is programmed to the "Warning Lamp" option, J1/P1:29 is available for the connection of a red warning lamp. The warning lamp is used to alert the operator that an engine problem is occurring. The warning lamp also indicates when the engine is being derated or the lamp will indicate that shutdown will take place.

If this parameter is programmed to "Option 1", there will be up to three discrete lamp outputs that are available for use to indicate specific engine problems. "Option 1" configures J1/P1:29 for the connection of a low oil pressure lamp and "Option 1" also configures J1/P1:31 for the connection of a high coolant temperature lamp. If a coolant level sensor is used, then J1/P1:30 will also be available for the connection of a low coolant level warning lamp. If the parameter for the "Coolant Level Sensor" is programmed to No, then J1/P1:30 can be used to connect a PTO switch-on lamp.

"Coolant Level Sensor"

This parameter determines if the ECM monitors the input signal of the coolant level sensor. This parameter also determines the type of sensor that is installed.

"Engine Coolant Temperature Derate Enable Status"

Note: This parameter is not supported on Dec 2003 and newer software. This parameter may be turned OFF. This parameter may also be locked out.

This parameter allows the coolant temperature derate to be enabled or disabled. When the coolant temperature reaches 103 °C (217 °F), the engine power is derated by three percent. When the coolant temperature reaches 104 °C (219 °F), the engine power is derated by six percent. 166-14 Rated Engine Power Special Instructions becomes active when the ECM derates power to the engine.

Note: This parameter will not disable the engine monitoring of the engine coolant temperature. If 110-00 High Coolant Temperature Warning or 110-11 Very High Coolant Temperature is active, the ECM will take action relative to the programming of the "Engine Monitoring Mode" parameter.
