4.4. Alarms
4.4.1. Temperature probe fault alarm
If the probe is faulty or not connected, or the temperature given is too
high (signal from the probe interrupted) or too low (short-circuited probe),
the system activates an alarm signal.
A buzzer goes on and off for about 10 seconds while the symbol for the
heating element alternates with that for the alarm
. The backlighting changes from
white to red.
If the faulty probe turns out to be the one for the top of the oven (TEMP
1), the temperature shown on the first line of the display will no longer be
the average between the probes at both the top and the bottom but only
that taken by the bottom temperature probe (TEMP 2). This allows the
user to continue cooking whilst waiting for technical assistance.
Interrupting the cooking cycle with the "start" key puts the system in the
“ON” state; the backlighting goes back to being white but the alarm
symbol remains highlighted (not alternating) in place of the
symbol for the top heating element.
After having identified a fault, it is necessary to turn on and turn off the
system with the "on/off" key to restore all the
system’s functions .
Conversely, if the faulty probe turns out to be the one for the bottom of the
oven (TEMP 2) the temperature shown on the first line of the display will
no longer be the average between the probes at both the top and the
bottom but only that taken by the top temperature probe (TEMP 1).
Interrupting the cooking cycle with the "start" key puts the system in the
“ON” state; the backlighting goes back to being white but the alarm
symbol remains highlighted (not alternating) in place of the
symbol for the bottom heating element.
After having identified a fault, it is necessary to turn on and turn off the
system with the "on/off" key to restore
all the system’s functions.
If both the probes are faulty, the buzzer sounds at regular intervals for 30
seconds while the symbols for the top and bottom heating elements are
