A graphical representation of the behaviour during CO detection can be found in chapter Fig.
8-29 Parameter CO- controller - Behaviour during CO detection.
Fig. 8-31 Behaviour during firing rate change
CO Threshold: Increasing air while changing the direction of the firing rate
Number of optimisation points which change the current optimisation value in the direction of
increasing air pressure immediately after changing the firing rate direction (P231).
CO Threshold: Increasing air while changing firing rate (without the direction of the firing rate)
Number of optimisation points which change the current optimisation signal in the direction of
increasing air pressure immediately after a firing rate change (P248).
