Pressure switch signal
Signal Electric panel over
temperature
Electronic board failure alarm
Oven off failure alarm
The oven turns off the fans
and the cooling fan 30 minutes
after STOP but does not turn
off.
The oven turns off the cooking
fans 30 minutes after STOP but
does not start the procedure to
shutdown electronics
The flame is unstable and
reddish, sometimes the alarm
buzzes:
BURNER BLOCK
The oven does not reach
Set Point but reaches
overtemperature
Oven overcooks
Pressure switch stuck
Rear cooling fan ineffectiveness
If stop or cooling is pressed, the burner
does not turn off; the flame continues to
burn because of the baking fan vent
since it is still powered-up during flame
check (BURNER relay
glued)
Oven turned off irregularly with the
emergency stop button
Electricity grid sag
Power grid voltage drop because of the
application type
TIMER relay slave board failure
Prolonged cooling fan operation
in the hidden parameters
Gas valve unregulated output pressure
Side panels excessively low
Reset for the wrong gas type
Wrong gas supply pressure
Thermocouples defect
UK/31
Check the condition of the pressure switch
when the oven is turned off and the electric
and pneumatic connection then replace the
damaged components
Ensure that the ventilation produced by the
rear cooling fan is effective and reaches
the electric board
Replace circuit board
Instruct operator on the correct procedure
to turn off the oven unless the emergency
button must be pressed to secure the
equipment.
Ignore this warning because the error is
caused by external factors
Check if for some reason the oven's
installation setting may cause a voltage
drop that will turn off the oven abnormally
(e.g. refrigerators, compressor start up, etc
...) and eliminate the cause
Check relay condition on the slave board
on the opposite side of the gear motor.
Replace electronic board if necessary.
Check "Auto shutdown" in the hidden
parameters
Check that the output pressure from
the valve is 0 otherwise adjust; if it fails to
adjust, replace the valve
Lift the side panels
Check that the oven is regulated properly
for the type of gas power supply and the
outgoing pressure from the valve gas is 0
mbar.
Ensure that gas and supply pressure are
set as shown in the instruction manual (for
your country)
Check position, cleanliness and status of
the thermocouple
