6.9.10 Reset push-button anomaly

if the reset button breaks or is kept pressed for more than 60 sec-
onds, the fault is indicated by the blinking of the led (see section
6.9.2) as long as the fault is present.
This fault is merely a visualisation.
 If the fault is detected during pre-purging or safety time, the
burner does not stop (the start-up sequence will continue).
 If the fault is detected during operation, the burner does
stops and stays stopped with the fault signal active.
 If the fault is detected during a lockout, the fault is not sig-
nalled and the burner cannot be reset.
When the fault disappears, the LED stops flashing.

6.9.11 Frequency main supply anomaly

The control-box automatically detects the value of the frequency
of the main supply in the range of 50 - 60 Hz, in both cases work-
ing times are verified. The fault is indicated by way of the blinking
LED (see section 6.9.2).
 If the anomaly is detected before heat demand the burner
does not start.
 If the fault is detected during the pre-purging, the burner
remains in purge condition and the fault is appropriately sig-
nalled.
 The fault is not detected during normal running, the burner
remains in this state.
When the fault disappears, the burner restarts.

6.9.12 Internal voltage anomaly

The control-box automatically detects if the internal voltage
works correctly. The fault is indicated by way of the blinking LED
(see section 6.9.2).
 If the anomaly is detected during the initialisation check time,
the burner does not start.
 If the anomaly is detected after a lockout the burner does not
start.
 If the anomaly is detected after a shut-down test, the burner
does not start.
 The fault is not detected during normal running, the burner
remains in this state.
When the fault disappears, the burner restarts.
Start-up, calibration and operation of the burner

6.9.13 Checking the fan motor

The control box automatically detects the presence of the fan mo-
tor and, in the event of a fault, it performs a lockout. The lockout
is indicated by the flashing led (see section 6.9.2).
6.9.14 Checking the electronic circuit controlling the
oil valve
The control box detects the presence of a fault inside the elec-
tronic circuit controlling the oil valve, the fault is indicated by the
flashing led (see section 6.9.2):
 if the anomaly is detected during the initialisation, the burner
goes into lockout.
 if the anomaly is detected during the pre-purging, the burner
goes into lockout.
 During a recycling, if the fault is detected, the burner does
not start and goes into lockout.
 If the anomaly is detected during running position the burner
remains in operation.
The fault is not detected if the burner is in lockout.

6.9.15 EEprom check

The control-box automatically detects if EEprom memory of mi-
cro-controller has failed and will perform a lockout. The lockout is
indicated by flashing led (see section 6.9.2).
