4.24 Setting FGR curve points
The FGR curve points are set at the fuel-air ratio curve. During the time the curve menu
is in use, the state of the FGR function does not change. This means that if the AUX3 is
still at the
ignition position
when setting parameters, it maintains the position until the
curve setting is completed.
At this position, the recirculation duct remains in
ignition position
, and the AUX3 is
marked with
#
on the screen. The position value of the AUX3 can be changed, but it
will not follow the readjustment for that period of time. The changed value can also be
stored.
If the AUX3 is not marked with # when setting parameters, it is already on the ratio
control curve, and follows the readjustment of the position value immediately.
After time period or temperature is reached, AUX3 will be released and FGR curve can
be made.

FGR temperature is stored to each curve point. Current FGR temperature can be
viewed from display using +/- buttons.
Make sure capacity is stable and FGR tempererature is within the normal operation
limits before storing curve point. This temperature is used to module the FGR valve
during operation.
