5. OPERATION
24 SYNTHESIS GAS
The oven continues working and only probe 1 is used to measure the
temperature. The control temperature is automatically raised by 40°C.
This variation in the temperature value is effected to correct the only
value taken in the coldest part of the oven and to simulate a value near to
the real one previously elaborated by making the average between the
hottest and coldest points. This allows the oven to be used even when a
probe breaks.
5.6.3.
“OVER”
If the temperature measured by the probe 1 exceeds 350°C and, at the
same time, probe 2 exceeds 450°C, the temperature value on the display
is replaced by the flashing word “OVER” and the alarm sounds
intermittently.
You can switch off the alarm by pressing the key .

5.6.4.
“BELT”
When the conveyor motor is broken or sends wrong signals to the circuit
board, the word “BELT” flashes on the display and the alarm sounds
intermittently.
This means that the cooking time does not correspond to the set value
and that specialized personnel are required to reset the functions of the
oven.
5.6.5.
“FAN”
If the pressure regulator fails for 5 consecutive seconds when the fan is
on, the temperature value on the display is replaced by the flashing word
“FAN”, the buzzer sounds intermittently and the oven heating (if on)
switches off. The alarm switches off automatically when the pressure
regulator contact is re-established or the oven is switched off (after the
switching off phase). The correct functioning of the pressure regulator
should then be checked.
While the alarm sounds, fan and conveyor (if on) remain activated.
The buzzer can be silenced by pressing the key .
5.6.6.
“PRESS”
If there is no pressure regulator (before switching on the fan), the word
OFF is replaced by the flashing word “PRESS”, the alarm sounds
intermittently and the switching on procedure terminates.
To reset the functioning of the oven, check that the pressure regulator is
working properly. To do this, check that the pipes are connected without
any constriction. If necessary, adjust the calibration with the screw located
