6.2 Commands and indicators
All commands and indicators for the use of the device are grouped in a single control
panel placed on the frontal panel. Its functioning is electronically managed in low
voltage.
In this manual, the buttons and indicators are identified with the relative symbol, and/or
with an imprint ([K…] for pushbuttons, [Z…] for indicators).
The functioning of every command is described hereby: to obtain the best results, an
acknowledgment is suggested.
ON/OFF Pushbutton [K1]
When the electric supply is connected, the machine is ready to be turned on, the green indicator light [Z1] is on. By
pressing the button, the device turns on and the other buttons are enabled. The display shows the total refrigerating time
previously set (in prime minutes).
SETTING Pushbuttons [K3] - [K4]
By pressing these commands, the number of minutes visualised on the display will be increased or decreased (1…99).
Note: It is suggested to set the refrigerating time when the device is idle, generally between 8 and 12 minutes
depending on the kind and quantity of the mixture. It is possible to increase or decrease the timing even during
the refrigeration for particular needs.
In any case the timer will automatically memorise, as total time, the minutes VISUALISED ON THE DISPLAY
after having pressed one of the setting pushbuttons.
BEATING Pushbutton [K2]
By pressing the pushbutton, the rotation of the beater goes CLOCKWISE. Press again the pushbutton to stop the beater.
The relative lighted indicator [Z2], signals that the beater is rotating CLOCKWISE.
Note: Pressing the BEATING Pushbutton when the REFRIGERATION command is activated ([Z5] indicator lighted)
stops the refrigeration, and the timer is put in PAUSE. By pressing again the pushbutton to start the beating,
the refrigeration starts again.
REFRIGERATION Pushbutton [K5]
By pressing the pushbutton (after having set the timer) what follows will be commanded:
- The start up of the refrigerating system (the [Z5] indicator of this button lights up);
- The beating, automatically, clockwise (the BEATING indicator [Z2] lights up)
- The timing control, signalled by the flashing spot visualised on the display, at the left of the residual refrigerating time.
The relative indicator [Z5], when lighted, indicates that the refrigerating system is activated. It remains in function until:
- a new pressure of the REFRIGERATION Pushbutton, or that of the BEATING Pushbutton [K2];
- at the end of the pre- set time on the timer. In this case the timer remains in function to avoid the formation of ice on the
cylinders walls (the [Z2] indicator is still lighted). To stop it, press the BEATING Pushbutton [K2].
