CALC function
The diagram (Fig. 37) 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. 38) 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 37.
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.
