Parameter mode (PArA)
Displays the complete list of parameters and allows you to mod-
ify/program it.
The parameters level is subdivided into groups:
000: InF
Internal parameters
Carrying out backup/restore procedure.
100: ParA
General parameters
Information and identification data of the system.
200: ParA
Checks on the burner
Safety intervention times of the various phases
(setting parameters and leak detection control
times).
400: Set
Setting work points
Adjusting the rpm of the fan on start-up (P0), at
the minimum (P1) and at the maximum (P2).
500: ParA
Fan parameters
Setting the adjustment field of the number of rpm
of the fan at start-up (P0), at the minimum (P1)
and at the maximum (P2),ascent/descent ramps.
600: ParA
PWM fan parameters
Setting the PWM signal/times adjustment field of
the fan.
Setting the analogue input signal (3 positions,
0...10V, 0...20mA, 4...20mA, 0-135 Ω) used for
the modulation.
700: HISt
Log of the errors:
Choice of different visualisation modes for the
errors log.
900: dAtA
Process information
Displaying the value of the PWM signal (%), the
control box power supply voltage and the inten-
sity of the flame signal.

Parameters level
The parameters in the unit's memory can be displayed or modi-
fied in the Parameters level.
To pass to the parameters level a password is required.
With the LME7..., the control characteristics of the burner are
mainly established by the parameter settings. Each time that the
unit is started, the settings of the parameters should be con-
trolled.
The LME7... should never be transferred from one system to an-
other without the parameters matching those of the new system.
The parameters and the settings can be modified
only by qualified personnel.
DANGER
See the list of parameters for controlling the parameters that are
read-only or that can also be changed (See List of parameters
PME71.901... on page 63).
Key:
SO = Service operator (password for service);
OEM = Manufacturer (password for manufacturer).
Calibration and operation
To access this level, refer to "Access procedure with password".
Once the access procedure has been carried out, the display will
show "PArA" for a few seconds.
Select the desired group of parameters with keys "+" and "-",
and confirm by pressing the key "i/reset".
Within the group you have chosen, scroll through the list with the
keys "+" and "-". At the end of the list, the display shows "End".
To return to Normal visualisation mode, simultaneously press the
keys "+" and "-" (esc) twice.
To modify a parameter, refer to "Parameter modification proce-
dure".

All the parameters are checked in the factory.
Modification/tampering may compromise the
good operation of the burner and cause injury to
people or damage to things. In any case, modifi-
cations must be carried out by qualified personnel.
