Technical description of the burner

Control box (LME22.2...)
Warnings
➤
All interventions (assembly and installation operations,
assistance, etc.) must be carried out by qualified personnel.
➤
Before modifying the wiring in the control box connection
area, fully disconnect the system from the power supply
(omnipolar separation).
➤
Protection against electrocution from the control box and all
connected electric components is obtained with the correct
assembly.
➤
Before any intervention (assembly and installation opera-
tions, assistance, etc.), ensure the wiring is in order and that
the parameters are correctly set, then make the safety
checks.
➤
Falls and collisions can negatively affect the safety func-
tions. In this case, the control box must not be operated,
even if it displays no evident damage.
For safety and reliability, comply with the following instruc-
tions:
–
avoid conditions that can favour the development of conden-
sate and humidity. Otherwise, before switching on again,
make sure the control box is perfectly dry.
–
Static charges must be avoided since they can damage the
control box’s electronic components when touched.
Use
The control box is a control and supervision system of medium
and large capacity forced draught burners, for intermittent opera-
tion (at least one controlled shutdown every 24 hours).
Installation notes
•
Check the electric wiring inside the boiler complies with the
national and local safety regulations.
•
Install switches, fuses, earth connection etc. in compliance
with local regulations.
•
Do not confuse the powered conductors with the neutral
ones.
•
Ensure that spliced wires cannot get into contact with neigh-
bouring terminals. Use adequate ferrules.
•
Arrange the H.V. ignition cables separately, as far as possi-
ble from the control box and the other cables.
•
When wiring the unit, make sure the 230V AC mains voltage
cables are run strictly separate from extra low-voltage cables,
to avoid the risk of electrocution.
Electrical wiring of the flame detector
It is important for signal transmission to be almost totally free
of any disturbances or loss:
•
Always separate the detector cables from the other cables:
– the line capacity reduces the magnitude of the flame sig-
nal;
– use a separate cable.
•
The cable length must not exceed 1 m.
•
Respect the polarity
•
Insulation resistance:
– must be at least 50 M
Ω
between the ionisation probe and
the earth;
– a dirty detector reduces the insulation resistance, fostering
leakage currents.
•
The ionisation probe is not protected against the risk of elec-
trocution. When connected to the electricity supply, the ionisa-
tion probe must be protected against any accidental contact.
•
Position the ionisation probe so that the ignition spark cannot
form an arc on the probe (risk of electric overcharge).
