Middle points are set manually by decreasing load manually for example in 10%
distances. Note that residual oxygen level is sufficiently over aired if the burner is
equipped with O
2
trim control. Oxygen residual level is set 1% higher than the normal
level. There can be 15 curve points at the maximum. Set at least 10 curve points for O
2
trim control.
Measure fuel consumption on every adjusting point so that the set of
curves correspond to the genuine load situation.
Check combustion values of ignition capacity with flue gas analysis.
When curve points have been set, exit from curve setting menu level, and set the
burner to operate on minimum load from manual operation menu level.

4.23 Activating FGR
Burner equipped with FGR can also be used without FGR. Whenever
you change FGR on or off, you need to recheck fuel-air ratio curves.
FGR can be activated from:
Params. & Display

Flue gas recirc.
↵
FGR mode

It is recommended to commission the plant first without flue gas recirculation (FGR).
Thus the fuel-air ratio control system is set as if the plant operated without the FGR
function.
When all other settings have been made, create FGR curve points at ratio curve. The
FGR function will become active after you have stored the curve point settings.
During the time the curve menu is in use, the state of the FGR function does not
change. This means that the AUX3 for FGR is still at the
FGR closed
position until
parameter setting is completed.
The parameters for FGR mode have been set at the factory. The commissioning
personnel will adjust the settings at start-up if needed.
For further instructions, see the section
