mode selection section 16.5 of this document for more information on the
configuration of these switches.
17.2.3 Engine All Speed Governing Installation
The All Speed engine governing feature requires no special installation other
than a method of engine speed demand. Please refer to the engine speed
demand section 11.0 of this document for more information on the methods
supported by the engine ECM.
17.3 Rating Selection Using EST
Some engines will have the capability to run more than one power rating. If
this is the case, the highest allowed rating may be changed via the “rating”
parameter on the configuration screen with EST. Note however, that the
engine may not be running the highest enabled rating due to the status of the
mode switches or due to requests from another electronic module on the
machine over the J1939 datalink.
17.4 Engine High Speed Governor (Governor Run-Out)
17.4.1 Engine High Speed Governor Operation
The 1204F and 1206F series engine range offers the ability to configure the
run-put gradient of the High Speed Governor (HSG) via the configuration of
the engine Rated Speed (RS) and the engine High Idle (HI).
Note: Not all engine ratings support the configuration of the engine RS.
The HSG curve is a linear line. The slope of this line can be adjusted using
the HI and RS speed settings. The line determines the response of the
engine once the engine speed enters the HSG controlled area of the torque
curve. Figure 15.4 Shows a HSG run out line with the same rated speed and
two different HI settings.
