5. SAFETY DEVICES
Limbs shearing-prevention safety device (batch freezer): Implemented by means of a
safety circuit compliant with the European directive, it intervenes when the door is opened
and/or when the safety grid on the hopper is lifted, temporarily switching the machine to
STOP mode.
Limbs shearing-prevention safety device (heater): Implemented by means of a safety
circuit compliant with the European directive, it intervenes when the lid is opened,
temporarily switching the machine to STOP mode.
Motor overheating safety device: Implemented by means of automatic reset thermal
relays; they protect the machine's beater motors from overloads, by signalling the relative
alarm message on the display, emitting an intermittent acoustic signal and enabling to
reset directly from the push button control panel.
Semi-hermetic compressor motor overheating safety device: Implemented by means
of an automatic reset thermal relay; it protects the machine compressor motor operation
from overloads, by signalling the relative alarm message on the display, emitting an
intermittent acoustic signal and enabling to reset directly from the push button control
panel.
Chiller circuit over-pressure safety device: implemented by the approved automatic-
restoration safety pressure switch; it protects the integrity of the chiller circuit from
overpressure.
Heat elements safety device: implemented by means of safety thermostat; it protects the
heat element from overheating, by signalling the relative alarm message on the display,
emitting an intermittent acoustic signal and allowing restore directly from the push button
control panel.
Protection against short circuit of auxiliary utilities: Implemented by fuses which
intervene on the logic unit or auxiliary power supply in the event of short-circuits.
SELV safety circuit: the push button control panel is powered at low voltage by means of
an approved dual-insulation safety transformer, protected against short circuits by fuses.
Bain-marie fluid level safety device: implemented by a conductivity probe inside the tank
which signals alarm on the display and coupled with an intermittent acoustic signal if the
fluid level is insufficient.
