Start-up, calibration and operation of the burner
• Pressing button "A" and button "+" increases the fan speed
and therefore the burnt output. Slowly increase the speed of
the fan checking the appearance of the flame, if possible, and
the value of the CO and CO2 to understand whether the burn-
er has been sufficiently calibrated. If necessary stop increas-
ing the speed and use the
maximum screw of the gas valve
to increase the gas flow rate: turn the screw V1 anticlockwise
(unscrew); to reduce the gas flow: turn the screw V1 clock-
wise (tighten).
• Proceed in steps until the maximum speed is reached (oP:
100) .
• Press the "+" or "-" together (ESC function) to return to the
normal operation.
• Press button "A" together with button "+" or "-" > 5 seconds
(value flashing on the display) to access the manual opera-
tion.
• Pressing the "info" button passes from the minimum modu-
lation (P1) to the maximum modulation (P2). Perform these
steps to perform the calibration of the minimum and maxi-
mum output points.
• Act on the valve settings, using the minimum screw for the
minimum output (P1) and the maximum screw for the maxi-
mum output (P2), to calibrate the combustion (CO and CO2).
• Act on the speed values for minimum output (P1) and maxi-
mum output (P2) pressing button
"A" and button "+" or "-" to
modify the 10 rpm.
NOTE:
The value of P2 can be increased up to the predefined maxi-
mum value (P2max factory set value). If this value can not be
reached (depends on the output and the back pressure of
the combustion chamber), the value oP: will be lower than
100 and cannot be confirmed. The P2 value must therefore
be decreased until oP can be seen: 100. in this case the val-
ue can be confirmed by pressing the "info" key. if no opera-
tion is carried out for a time of >30 seconds, LME7 passes
automatically to the normal operation mode. Keep the but-
ton “A” pressed together with the button “+” or “-” > 5 sec-
onds to return to the manual operation.
• Press buttons "+" or "-" together (ESC function) to exit the
manual operation and activate the automatic operation.
• Reset the external modulation control (control with 3 points or
analogue signal). In the automatic operating position the out-
put requisites of the external load regulator are valid.
NOTE:
When the burner is operating, the control box display shows
"oP:" meaning modulating operation. The display after "oP:"
indicates the value in percentage of the speed. The speed
corresponding to 100% is that of point P2 (maximum speed).
• To calculate the approximate number of fan revolutions from
the percentage
"oP" it is necessary to multiply the speed set
at point P2 by the percentage read (for example, with
P2=6000rpm and
oP =20% the speed of the fan is about
1200rpm).
• If the speed set at point P2 is changed (to lower the burnt out-
put, for example) also the current value, equal to “ oP ”, is
changed (e.g. P2 = 5000 rpm and oP = 20% the fan speed is
about 1000 rpm).
NOTE:
to safeguard the settings on the PME7 program module, a
manual backup must be carried out. Also see chapter "Man-
ual Backup".
WARNING
Eventual modifications to the parameters and the
settings should be set and saved in the memory
on-board the unit.
To save the modified settings of the PME7... pro-
gram module, the backup should be activated
manually. If this is not respected, the safety func-
tions and the set settings could be lost (P0, P1
and P2 values).
WARNING
At the first start-up, or else after replacing the pro-
gram module, it is necessary to check, immediate-
ly after the reset process, the sequence of the
functions and the settings of the parameters. If
this is not respected you risk losing the safety
functions.
WARNING
If the parameters have been changed, you need
to make a backup! If this is not respected, the
safety functions and the set settings could be lost
(P0, P1 and P2 values).
