● burner minimum load, note ratio
● set fan rotation speed as small as possible, but not under 60%
● check combustion values with flue gas analysis
● check the combustion flame
● set load value and point load is determined according to current fuel consumption
as a percentage of maximum load
In the settings for air servomotors and frequency converter control, residual oxygen is
adjusted as desired for each curve point.
When you have made changes, press

buttons to increase or decrease burner start
capacity.
Curve point 9 ver. 5
3. Servomotors follow an imaginary linear curve towards the maximum or minimum
load. The oxygen value can be monitored on the display. When increasing load,
monitor that combustion values do not increase to a hazardous level. If necessary,
set curve point for interval by pressing
Enter
, and correct servomotor positions to
return combustion values to a normal level. Press
Esc
to return to the initial state.
The curve point for maximum load will be set when fuel consumption for full load is
reached.
