10.0 Engine Protection System
Overview
The Engine Protection System monitors the engine systems for conditions that might
require the engine to either derate, or in some circumstances shut down. If any of the
monitored conditions exceed Engine Protection System thresholds, the functionality
will provide a visual warning to the driver. This warning allows the driver to adjust the
operation of the vehicle to correct the condition. If the customer has selected either
derate or shutdown, and the driver has not succeeded in correcting the condition, a
derate or shutdown sequence will be initiated. Derate provides reduced engine
performance to correct the engine condition. Shutdown will turn the engine off to
prevent imminent failure.
Standard Configuration

Derate
Derate allows the engine to provide a power reduction or a maximum engine speed
limitation. If an engine is equipped with derate, once a visual warning is provided a
derate will be implemented in an attempt to correct the condition and mitigate a
potential failure. Once a derate request has been triggered, the derate will implement
immediately.
Additional Configuration Options

Warning

Shutdown
Warning allows the engine to provide a visual indication that the Engine Protection
System has detected a condition that could potentially cause an engine failure.
Shutdown allows the Engine Protection System to turn off the engine if the driver
does not take action to correct the condition. When a shutdown request is triggered,
the engine will shutdown in 60 seconds.
