Basic Operating Principles
The powered machine is normally in the stand-by mode.
When a button is pressed, a vend cycle starts.
If a sale price is preset, before pressing the selection the required amount of money must be inserted by
means of coins.
According to the selection required and to the version of the machine, the vend cycle is composed by
some of the following procedures.
5.1
Preparation of hot drinks from instant ingredients
This procedure is usually carried out after the cup is correctly positioned under the outlet pipes of the
beverage. More than one procedure of this sort can be carried out simultaneously or in sequence during
a vend cycle.
1) When the solenoid valve corresponding is activated, the preset quantity of water is poured to dissolve
the ingredients;
2) The water coming from the water refilling tank, in which the water level is kept constant, is conveyed
under pressure in the boiler by means of a pump;
3) If present, the mixer motor is activated;
4) The geared motor activates the screw feeder, in the canister of the corresponding ingredient, which
pours the correct quantity of ingredient in the mixing bowl. More than one canister of ingredients can
be activated simultaneously for the same mixing bowl;
5) If present, the motor of the mixing bowl is switched off.
5.2 Preparation of the Espresso coffee
This process is carried out in the models equipped with the espresso coffee group after the selection
button corresponding to coffee beans selections has been pressed. The execution priority between this
process and the process for the preparation from instant ingredients is preset by the programme of the
machine and varies according to the selection chosen.
1) The coffee grounds are ejected into the waste bucket (this procedure can be carried out also after
10 minutes of inactivity of the coffee group);
2) The coffee group moves to the correct position to receive coffee dose;
3) The coffee grinder is activated for a time programmed by software;
4) The coffee group moves to the infusion position: this occurs when the coffee group motor is started.
The cup and the lower filter are moved upwards to close the brewer and press the compress of
ground coffee;*
5) The water coming from the water-refilling tank, in which the water level is kept constant, is conveyed
under pressure in the boiler by means of a pump. After the activation of a solenoid valve, the same
quantity of warmed water is then conveyed to the coffee group;
6) The coffee group ends the cycle.
* Procedures marked by asterisk may be carried out in a different order according to the electronic
setting of the machine.
