Safety Devices
During the running of appliance, some control
devices may activate and govern the correct
running of the machine. In other cases, they may
deactivate parts or the whole machine, to put the
appliance in safe conditions. Main controls are
described below.
GB
Door micro switch
If the door is opened, the magnetic switch placed
on the control board opens and, during blast-
chilling or shock-freezing, evaporator fans go off
and a warning message appears on the display at
the same time. This condition may also be
determined when the door is not perfectly aligned
to or near the control board: in this case with
machine in STOP phase, cycle start-up is
prevented, apart from start-up of the defrosting
cycle.
If a U.V. sterilisation cycle is active, the functioning
of the U.V. lamp is interrupted. The cycle continues
when the door is closed.
Protective Fuses
Some protection fuses in the general power supply
line are activated in case of overload.
High condensation temperature alarm
In the event of room conditions or functional
failures, which cause the condenser to exceed the
maximum temperature value, an alarm is triggered
and stops the machine running. The machine can
be run when an acceptable temperature value is
reset.
Evaporator Fan Micro switch
If the deflector is opened to inspect the evaporator
or fans, this micro switch positioned on the
evaporator
deflector,
functioning. Closure of the deflector with the
successive disappearance of the alarm on the
display, restores normal machine functioning.
