Monitoring System

| NOTICE |

|
The Engine Monitoring System is not a guarantee against catastrophic failures. Programmed delays and derate schedules are designed to minimize false alarms and provide time for the operator to stop the engine. |
The following parameters are monitored:
- Coolant temperature
- Oil pressure
- Engine speed
- Atmospheric pressure (Barometric pressure)
The coolant temperature, oil pressure, and the engine speed can trigger an engine shutdown.
- Atmospheric pressure (Barometric pressure) can trigger an engine de-rate.
The atmospheric pressure sensor (Barometric pressure sensor) can de-rate the engine. Operating the engine and increasing the altitude will de-rate the engine in accordance with emission regulations. The start of the de-rate will be determined by the flash file that is installed.
