Function - General safety functions
Description of functions
When the system is switched on for the
first time, after a power failure or safety
shutdown, after a lack of gas or after the
system has been out of operation for 24
hours, the pre-ventilation period of 24
seconds begins.
During pre-purge period:
- blower pressure is monitored
- the combustion chamber is monitored for
flame signals.
At the end of the pre-purge period:
- ignition is switched on.
- main and safety valve are opened.
- burner starts.
Monitoring
The flame is monitored by an ionisation
probe. The probe is insulated and
fitted to the gas head and is routed
through the flame disc into the flame
zone. The probe must not have any
electrical contact with earthed parts. The
burner switches to lock-out if a short
circuit occurs between the probe and
the burner earth.
During burner operation, an ionised
zone is produced in the gas flame
through which a rectified current flows
from the probe to the burner head. The
ionisation current must be at least 1,5 μA.
Safety functions
- If no flame is produced when the burner
is started (gas release), the burner will be
switched off at the end of the safety
period, lasting no more than 3 seconds,
and the gas valve will close.
- If the flame goes out during operation,
the gas supply is interrupted within one
second. A restart takes place. Once the
burner starts, operation is continued.
Otherwise, a safety lock-out occours.
- If there is a lack of air during reventilation
or operation, a safety lock-out occours.
- If there is a lack of gas, the burner does
not begin operation or switches off.
A waiting time of 2 minutes follows. This is
followed by a further start attempt. If there
is still no gas pressure, a further waiting
time of 2 minutes follows. The waiting time
can only be reset by interrupting the
power supply to the burner.
Waiting times: 3 x 2 min, then 1 hour.
In the event of controller shutdown
- Controller thermostat interrupts heat
request.
- Gas solenoid valves close.
- Flame goes out.
- Burner motor switches off.
- Burner is ready for operation.

The E-BCU GAS fuel gas/LPG control and
safety unit controls and monitors the
forced draught burner. The
microprocessor-controlled program
sequence ensures maximum stability of
time periods, regardless of fluctuations in
the power supply or ambient temperature.
The design of the automatic combustion
control unit protects it from the effects of
brownouts. Whenever the supply voltage
drops below its rated minimum level (170
V), the control unit shuts down - even in
the absence of a malfunction signal. The
control unit switches itself back on again
once the voltage has exceeded the 178 V.

Start up - Air pressure switch adjustment - Setting gas pressostat
Air pressure switch calibration
The air pressure switch is provided for
monitoring the pressure of the
combustion air fan.
Unscrew screws A and B and remove
cover C.
After the air and gas setting you have to
calibrate the air switch with the burner
working on the low flame by slowly turning
the relative knob clockwise until the burner
locks out. Read the value and then
decrease it by 15%.
WARNING: the air pressure switch shall
prevent the air pressure to go below 85%
from the adjustment value in order to
prevent the CO in the fumes to exceed 1%
(10000 ppm).
Min gas pressure switch
The gas pressure switch has the function
to check that the gas pressure before the
gas valve does have the minimum
pressure to make the burner running
correctly.
Unscrew off and remove cover M.
- Set knob N to a value equal to 60% of
gas nominal feed pressure (i.e. for natural
gas nom. pressure = 20 mbar, set knob to
a value of 12 mbar; for LPG nom. pressure
of G30/G31- 30/37 mbar, set knob to a
value of 18 mbar). Screw up cover M.

Funzione - Funzioni generali di sicurezza
Descrizione del funzionamento
Alla prima messa sotto tensione, dopo
un'interruzione di corrente e una fase di
messa in sicurezza, dopo un'interruzione
di gas o dopo un arresto di 24 ore,
comincia un tempo di preventilazione di
24 sec.
Durante il tempo di preventilazione:
- la pressione dell'aria viene monitorata.
- controllo della presenza di eventuali
segnali di fiamma anomali.
Al termine del tempo di preventilazione
- l'accensione e inserita.
- l'elettrovalvola principale e di sicurezza e
aperta.
- il bruciatore si avvia.
Sorveglianza
La fiamma viene monitorata da una sonda
di ionizzazione. La sonda e montata in
modo isolato sulla testa del gas ed e
diretta attraverso il disco fiamma nella
zona della fiamma. La sonda non deve
avere alcun contatto elettrico con
componenti messi a terra. Se compare un
cortocircuito tra la sonda e la massa del
bruciatore, il bruciatore entra in stato di
anomalia. Durante il funzionamento, nella
fiamma del gas si crea una zona
ionizzata, attraverso la quale circola una
corrente raddrizzata dalla sonda verso il
boccaglio. La corrente di ionizzazione
deve essere superiore a 1,5 μA.
Funzioni di sicurezza
- Se all'avvio del bruciatore (rilascio del
gas) non si forma la fiamma, il bruciatore
viene arrestato al termine di un intervallo
di sicurezza di max. 3 secondi, la valvola
del gas si
chiude.
- In caso di anomalia della fiamma
durante il funzionamento, l'alimentazione
del gas si interrompe nella frazione di un
secondo. Viene avviata una nuova messa
in funzione. Se il bruciatore si avvia, il
ciclo di funzionamento prosegue. In caso
contrario si instaura una fase di messa in
sicurezza.
- In caso di mancanza d'aria durante la
preventilazione o il funzionamento, si
instaura una fase di messa in sicurezza.
- In caso di mancanza di gas, il bruciatore
non si mette in funzione e/o si arresta.
Segue un tempo di attesa di 2 minuti al
termine del quale avviene un nuovo
tentativo di avvio. Se la mancanza di
pressione del gas perdura, si avvia un
nuovo tempo di attesa di 2 minuti.In
questo caso, il tempo di attesa puo essere
interrotto esclusivamente dallo
spegnimento del bruciatore. Tempo di
attesa: 3 x 2 min., poi 1 ora.
Arresto di regolazione
- Il termostato di regolazione interrompe la
richiesta di riscaldamento.
- Le valvole gas si chiudono.
- La fiamma si spegne.
- Il motore del ventilatore si ferma
- Il bruciatore e pronto per il
sucessivo funzionamento.
