Behaviour during CO detection
Fig. 8-29 Parameter CO- controller - Behaviour during CO detection
1 Increasing air: Initial value at upcoming CO detection [digit]
Number of optimisation points that raise the current correction signal in the direction
of excess air immediately after the CO threshold has been detected.
Factory setting and value range 0 ... 300 corresponds to 0 ... 300 digit.
2 Increasing air: Speed gradient after CO detection [digit/s]
Number of optimisation points that increase the current correction signal in the direc-
tion of excess air during a direction change of the firing rate.
Factory setting and value range 0 ... 400 corresponds to 0 ... 400 digit.
3 Decreasing air: (Falling) speed gradient after decreasing CO correction [digit/s]
After a completed optimisation, the correction signal leaves the associated optimisa-
tion point by the set number of digit in the direction of excess air.
Factory setting and value range 0 ... 200 corresponds to 0 ... 200 digit.
