Accelerator Optionals

Feature Description
This feature allows the user to determine the type of engine
governor control. The two types available are the automotive
(minimum or maximum) and Variable Speed or All Speed
Governor types. The automotive governor provides a constant
fueling for a given accelerator position. With the automotive
governor selected the engine speed can vary with changes in
engine loading for a constant accelerator position.
The Variable Speed governor provides a constant engine speed
for a given accelerator position. With the Variable Speed
governor selected the engine speed will remain constant with
changes in engine loading for a constant accelerator position.
The Variable Speed governor is an option. It is best suited for
applications where a constant engine speed is desired to
perform a desired task where engine or power take-off speed
must remain constant.
Driver Activation/Deactivation
The selection of the governor type can be accomplished two
ways. If the vehicle is equipped with a cab-mounted switch, the
driver can activate this switch to select between the automotive
or Variable Speed governor. If the cab switch is not available the
TM
INSITE service tool can be used to select the desired
governor type.
Interaction with other Features and Parameters
This feature does not interact with any other feature or
parameter.
Disadvantages
For applications that require a constant engine speed to perform
a desired task, the automotive governor will not hold the engine
or Power Take-Off speed constant for a given accelerator
position.
