CALC function

The diagram (Fig. 38) 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. 39) shows the fuel modulation curve when,
after the modification of point " P5 ", the recalculation of all the oth-
er points is not carried out.

6.7.3 Modification of parameter "acceleration /
deceleration ramp"
The burner leaves the factory with the parameters 522 (acceler-
ation) and 523 (deceleration) already set.
If the operator needs to modify them, proceed as follows:
Access the Parameters Level referring to "Access procedure
with password" on page 39.
Using the "+" key select the parameters group 500 :
Using the "+" key select the parameters group 522 (accelera-
tion) :
press the "info" key to change parameter 522 .
The set value must be greater than at least 20% of the parame-
ter " ACCELERATION RAMP " of the Inverter.

With the key "+"
Select the parameter 523 (deceleration) :
press the " info " key to change parameter 523 .
The set value must be greater than at least 20% of the parame-
ter " DECELERATION RAMP " of the Inverter.
