Start-up, calibration and operation of the burner
6.12.0.1 Procedure for inserting and adjusting points on
the modulation curve
Nine adjustment/calibration points (P1 - P9) can be inserted in
the control box for each servomotor, varying their position by de-
grees and, consequently, the quantity of air and fuel introduced.
The ignition point P0 is independent of the minimum modulation
value. This means that, in the event of difficulty, it is possible to
switch on the burner at a value other than the modulation mini-
mum (
P1 ).
To access the Parameter mode (group 400) referring to the “Ac-
cess procedure with password” on page 44.
To insert or adjust a point, proceed as follows.
Using the keys “+” and “-” insert/select the curve point you want
and wait for it to flash: this means that the servomotors are now
positioned on the values shown on the display and which corre-
spond to the point previously set.
It is now possible to insert/modify the position by degrees.
For the fuel servomotor, keep the key “F” pressed (the position
in degrees flashes) and press the keys “+” or “-” to increase or
decrease the value.
For the air servomotor, keep the key “A” pressed (the position in
degrees flashes) and press the keys “+” or “-” to increase or de-
crease the value.
To adjust the speed of the inverter (expressed in % and that is 50
Hz = 100 % ), keep the buttons “F” and “A” simultaneously
pressed, the percentage position blinks and press buttons “+” or
“-” to increase or decrease the value.
Select another point, or exit this area by pressing the keys “+”
and “-” ( ESC ) simultaneously.
6.12.0.2 CALC function
The diagram (Fig. 44 on page 46) shows how the fuel modulation
curve is modified if the values of point “
P5 ” are changed.
By keeping the “+” key pressed for more than 3 s, the points
from “ P6 ” to “ P8 ” are recalculated.
By keeping the “-” key pressed for more than 3 s, the points
from “ P4 ” to “ P2 ” are recalculated.
The diagram of (Fig. 45 on page 46) shows the fuel modulation
curve when, after the modification of point “
P5 ”, the recalculation
of all the other points is not carried out.
WARNING
The set value does not require confirmation.
