18.11.3 Direct entry of O
If the limit values of a plant are known, and if the CO limit need not be remeasured, the
O2 min. values can be entered directly.
P u n k t
O 2 - M i
P - L u f
On the first line, «Point», select the point number to be changed and confirm with
ENTER (point 1 can be adjusted). With the second line, «O2 Min Value», the O2 min.
value can be directly parameterized. The points will only be approached if, previously,
setting choice «P Air Man» has been used.
18.11.4 Measuring the O
On the first line, select the point number and confirm with ENTER. Now, select line «P-
Air Man» and confirm. After confirmation with ENTER, the ratio control system
approaches this point on the parameterized ratio curve, that is, air rate reduction «P-Air
Man» will be set to «0». The display on the second line changes to «Actual O
which will then be displayed.
P u n k t
O 2 - I s
P - L u f
By readjusting the air rate «P-Air Man», the amount of combustion air and thus the O2
value can be reduced. «P-Air Man» corresponds to the relative air rate reduction.
During the readjustment, all actuators on the curve parameterized as air-influencing will
travel to the relevant positions. When the O
O Value» will be entered as the «O
