Shearing-prevention system: realized by means of a safety circuit in conformity with the
European standard; it intervenes when the door is opened and/or the grid on the hopper is
lifted and temporarily switches the machine to STOP. The following message appears on
the display “ALARM. OPEN DOOR EMERGENCY”. Do not use this device to stop the
machine during batching. Always use the function STOP.
The machine also carries out a series of controls during production:
Production control
Carried out by the microprocessor by means of a current transformer. A wattmetric control
of the agitator motor is performed.
Amperometric safety control
During temporized batching cycles, the electronic card carries out the reading of the
agitator motor power input and stops the cycle in case the absorbed current value reach or
exceed the one foreseen on the testing card.
Batch freezing safety timer
It intervenes 35 minutes after batching start in case the minimum consistency value
established by the manufacturer is not reached. The compressor and the agitator stop, the
following message is visualized on the display “ALARM. BATCHING TIME-OUT”, and an
intermittent acoustic signal (beep) is issued.
It is necessary to check for the presence of anomalies in the cooling circuit and/or check
the mixture dosage.
Anti-icecream in the centre
In case the ice-cream, during batching, becomes a consistent mass, which can no more
be worked with the paddle and is collected in the centre of the agitator, the electronic card
stops the compressor and switches the agitator motor to high speed for 45”. Then the
machine automatically resumes the interrupted batching cycle.
