Start-up, calibration and operation of the burner
6.8 Start-up procedure
Check that the operator panel display shows the heat request
and
“OFF Upr” : this means it is necessary to set the modulation
curve of the burner.
Access the Parameters Level referring to "Access procedure
with password" at page 36.
The display screen displays the parameters group 400 .
Confirm with the key “i/reset”
The display visualises “run”
Confirm with the key “i/reset”. The burner starts up.
The display visualises all the phases and relative times in se-
quence. The phases are listed in section
"List of phases" at
page 18.
Phase 22:
Start of the fan motor.
Phase 24:
The burner goes to the pre-purging position, the air servomotor
opens the damper at 90°.
Phases 80, 81, 82, 83:
These phases relate to the valve seal test.
Phase 30:
The count of the pre-purging time pre-set in the factory begins.
Phase 36:
The burner goes to its switch-on position, point “ P0 ”, defined in
Tab. O at page 40: the display shows a flashing “ P0 ” indicator.
If the set value is adequate, confirm using the button “+” .
Otherwise, modify the ignition point, see the section "Procedure
for inserting and adjusting points on the modulation curve"
at page 38).
Phase 38:
The ignition phase begins and the spark goes off.
Phase 40:
The gas valves open (the count of the safety time begins). Check
the presence of the flame from the special inspection window,
and that the combustion parameters are correct. if necessary,
vary the degrees of opening/closing of the air and fuel servomo-
tors.
If the control box goes into lockout, press the keys
“+” and “-”
( ESC ) simultaneously: the display visualises alternately the lock-
out code for flame absence c: 4 ) and the relative diagnostic ( d: 3 ).
Solve the problem, referring to the paragraph "Ignition failure"
at page 48.
To unlock, see
"Reset procedure" at page 35. The display vis-
ualises “OFF Upr” .
Repeat the "Start-up procedure" .
Once it has ignited (point “P0” ), proceed with the calibration of
the modulation curve.
Press the button “
+ ”: the display visualises the flashing “ P1 ” indi-
cator and proposes the same settings as for point “ P0” .
Press the button“ + ” again: “ CALC ” appears on the display for a
few seconds.
