6.5.10 Adding Points
Should there be a previously saved curve that does not contain twenty points, additional points
may be added.
NOTICE
Up to 20 points can be programmed. A high resolution should also be used, since this ensures
precise combustion control. It is also possible, however, to store fewer than 20 points. This is
advisable, for example when entering an initial, approximate curve.
NOTICE
A definitive curve for the VMS should always comprise at least 10 points.
Turn selector switch (2) to SETTINGS
Turn selector switch (1) to FIRING RATE RATING (fir-
ing rate)
Run to desired firing rate
If the display shows a flashing number after the firing-
rate rating, instead of adding a new point an old one is
overwritten.
Turn selector switch (1) to SETPOINT
Switch (4) up or down until system is optimally adjusted
at the selected firing-rate rating.
VMS 5: Switch (1) to DISPLAY CHANNEL 5
the display shows setpoint and actual value feed-
back
Switch (4) channel 2 up or down until channel 5 is opti-
mally adjusted.
Turn selector switch (1) to ACTUAL VALUE FEED-
