Emulsifier Valve; Cappuccinatore Unit; Solenoid Pilot Valve; Single Micro. Gearmotor - Saeco MAGIC M2 Technical Manual

12.2

Emulsifier valve

(*only versions M2 and M1).
(*only versions B2 and B1).
EV1 EV steam Puts the steam circuit in communication with the
cappuccino maker.
The steam reaches the steam injector directly.
EV2
EV pressure discharge Steam vents into the tray which lowers the pressure in
the boiler and empties it if necessary.
EV3 EV hot water Intercepts water from the coffee circuit to dispense hot
water directly into the cup.
EV4 EV rinsing Intercepts hot water from the coffee circuit and sends
it to the air and milk suction circuit of the cappuccino
maker to dry it.
EV5
EV air discharge Makes it possible to intercept the "milk suction branch"
and "air suction branch" circuits: serves as diverter
during rinse phase with air/water.
EV6 EV air flow Inserts compressed air into the air suction circuit to:
+ - avoid demijohn effect milk jug - cup at end dispensing.
Compressor - empty internal circuit of the rinse water.
EV7 EV of air input Solenoid valve for the management of the frothed and
non frothed milk.
EV8
EV hot water Intercepts water from the coffee circuit to dispense hot
water directly into the cup.
12.3

Cappuccinatore unit

(*only versions M2 and M1).
1
Cappuccinatore unit
2 Dispensing spout unit
12.4

Solenoid pilot valve

1
Discharge of the liquids recovery tank (normally open).
2 Drip prevention of coffee in output.
3
Coffee input.
4 Coffee output.

Single micro. gearmotor

Power on
When the machine is switched on the gearmotor positions itself as follows:
• It presses micro 1 (see next section)
• The gearmotor changes the rotation direction and moves upward by ca. 1-2 mm
• The boiler begins to heat the water for ca. 45 seconds, absorbing full heating
power to reach the optimal temperature. After this the temperature is maintained
constant.
Coffee Cycle
1. The coffee grinder begins grinding (managed by the dosing unit micro)
2. Dosing unit open
3. The gearmotor (brew group) moves to dispensing position
4. Preliminary dispensing phase (brief pump activation, brief pause)
5. Product dispensing (pump operation time is determined by the quantity of
product dispensed)
6. The gearmotor moves to off position - coffee grounds are automatically expelled.
