2. OPERATING LOGIC
2.1. OPERATING MODES:
The appliance can operate in the following modes:
• User Programming Mode: From the user menu you
can change appliance programming as described
in the instruction booklet.
• Diagnostics Mode: this mode allows service
engineers to adjust operating and service
parameters. This menu contains all the user menu
items plus a series of more complex programming
options reserved for service personnel.
• Test Mode: Used by service personnel to
check operation of the appliance and its main
components.
2.2. USER PROGRAMMING MODE
This mode is accessed by means of the menu button (see instruction booklet)
2.2.1. MENU OPTIONS
The following options can be programmed by the

2.3. GROUND COFFEE DOSAGES
The coffee dosage depends on the rpm of the coffee
grinder (controlled by a sensor) and the mechanical
grind setting (by means of the adjuster knob).
2.3.1. DOSAGE PROGRAMMING FOR THE USER (AROMA FUNCTION)
You can select the quantity of ground coffee for
each coffee type (espresso, caffé, lungo coffee) by
setting the “Aroma” parameter. This serves to make
stronger or weaker coffee.
Aroma Type:
• 0: LIGHT (grinder speed of 45 rpm)
• 1: REGULAR (grinder speed of 50 rpm)
• 2: STRONG (grinder speed of 55 rpm).

2.3.2. DOSAGE PROGRAMMING FOR THE ENGINEER
In “Test” mode you can increase the rpm of the cof-
fee grinder in correspondence with each aroma type
(LIGHT, REGULAR, STRONG) by 2.5 rpm.
The available levels are as follows:
2.4. FACTORY SETTINGS
The machine is delivered with the following factory
settings:
Temperature level = 2 (Medium)
Water hardness = 3 (High)
Stand-by delay = 3:00
Prebrewing = 1 (short)
Espresso Quantity = 110
Caffé Quantity = 170
Lungo quantity = 290
Espresso Aroma = 1 (Regular)
Caffé aroma = 1 (Regular)
Lungo Aroma = 1 (Regular)
Power-on time = 0:00
Power-off time = 0:00
Display contrast = 6 (60%)
Waterlter=0(No)
Clock active = 0 (No)
Time visible = 0 (No)
Rinses permitted = 1 (Yes)
Note several factory setting parameters depend on the language set on the appliance:
- if any European language is selected the appliance will present EUROPE settings
- selection of USA English or Canadian French results in US settings.

2.6. SBS VALVE
Beverage dispensing
The SBS delivery valve (see fig. 2), which is
adjustable using the knob, serves to alter (increase
or decrease depending on the knob setting) the
owrateofwaterforbrewingintheunit.
This serves to alter the coffee brewing time (extraction
time)andconsequentlytheintensityofavour,while
maintaining the quantity of crema constant.
Function
With the SBS valve in its open position, an
accumulation of coffee is obtained inside the
diaphragm valve due to the low counter-pressure
of the SBS valve. Consequently the membrane
valve needle remains in the fully open position due
to resistance of the spring. The coffee is delivered
rapidly (see Fig. 3).
With the SBS valve in its closed position, an
accumulation of coffee is obtained on the valve
diaphragm resulting in a pressure build-up inside the
valve. The spring succumbs to the counter-pressure
and the valve element consequently reduces the
owofcoffee(seeg.4).
