02 TECHNICAL SPECIFICATIONS

2.3.1. Specification for the measurement of the coffee products temperature.
The temperature is influenced by the flow from the dispenser and stratification of temperatures in
the glass. In order to consider these phenomena and to introduce measures that allow comparisons
in controlled conditions, below guidelines must be followed:
Conditions:
a) Water temperature in tank: 23°C (+/-2°C).
b) It must be used a plastic cup (see picture N°1).
c) It must be used a thermocouple thermometer (e.g. type K - see picture N°2).
d) The coffee machine is tested without any change of parameters or calibrations, which may
affect the temperature of products, so the measurement of temperature must be done with
machine in default factory setting.
Procedure:
1. The temperature must be measured in the cup, immediately after dispensing. Cup has to be
placed on a non-metal surface using a thermocouple thermometer (Picture 1).
2. The temperature in the cup is measured by immersing the probe of the thermometer up to touch
the bottom.The probe then must be moved in a circular motion for 5/6 rotations. At the of the rotations, stop in the center of the cup (Picture 2).
3. The highest temperature measured during the rotations is the value we are searching for, and
that must be reported;
4. Test measurement: from end of dispensing to the end of rotations must be completed within 12
seconds.
5. the distance of the probe from the bottom of the glass is a function of the quantity of coffee dispensed: 10mm for 35gr - 17mm for 60gr - 35mm for 120gr and superior (Picture 3).
Limits of acceptability
The acceptance limits are divided by features and
products and are the following:
Espresso Coffee Italy Q.ty 25/40 gr.
Temperature of 1st product 69°C ≤ 85°C
Temperature of 2nd product 72°C ≤ 85°C

2.3.2. Specification for the measurement of the Milk products temperature.
Milk evaluation
To carry out the test, a partially skimmed UHT milk with a percentage of grease between 1.5-1.8%
at a refrigerator temperature Trefr. (between 4 to 10°C) must be used.
The milk product must be checked on a beaker of 250 ml of capability and with an inner diameter
of 70mm, brewing 100gr of product.
Parameters to be respected:
The parameters to be respected are: milk temperature and height of the cream. Each of these parameters, however, must be evaluated depending on the type of system used for the production of
hot milk. Actually three types of devices are present on the appliances:
• Manual system (pannarello)
• Semi-Automatic system (cappuccinatore)
• Automatic system (carafe, Pinless wonder system, etc.)
Milk temperature in the beaker:
System without Pinless Wonder: With milk at Trefr. (about 4-10 °C):
≥ 36
how does it work:
1. The cold milk is frothed with air in the first chamber.
2. Then, the frothed milk is heated in the second chamber thanks to the steam.

Height of the milk cream in the beaker:
Manual system (pannarello) ≥ 15mm on 100gr. of brewed product
Semi-automatic system (cappuccinatore) ≥ 20mm on 100gr. of brewed product
Automatic system: carafe, cappuccinatore, Pinless wonder e.g. (New Royal, Energica Pure, Intelia
EVO latte) ≥ 20mm on 100gr. of brewed product
How to measure the temperature of the milk.
1. The measurement is carried out in the beaker, immediately after the end of milk brew, positioned
on a non-metallic surface, using a thermocouple thermometer (eg. Type K). Stop the preparation
of mixed product: at the end of milk brewing, where “One Touch product” function is present.
2. The temperature is measured by immersing the probe of the thermometer, positioning the probe
inside the beaker at about 10mm from the bottom of the container, then the probe moves in
a circular motion for 3-5 turns, stopping at the end, at the center of the beaker. It detects the
maximum temperature reached in a time of relief between 3 to 5 seconds. It is important the
mixing of milk before the measurement at 10mm from the bottom of the beaker. If the mixing is
correct, temperature, for a few fractions of a second, during the measurement should not oscillate.

GAGGIA BABILA
02 TECHNICAL SPECIFICATIONS
How to measure the milk cream.
The temperature (Trefr or Tamb) of the milk doesn’t affect as much the test result on measuring
the milk cream; by convection is assumed to always use milk at refrigerator temperature Trefr..
Manual systems (Pannarello)
Pour 100cc. of milk at Trefr. in a beaker of 250 ml of capacity and with a inner diameter of 70 mm;
with machine in steam mode:
1.
2.
3.

Open the steam knob to discharger water circuit for 4 sec, then close the knob.
Place the beaker with the frother dipped in milk, open the steam knob to maximum and
start the chronometer.
After about 30 to 60 seconds, close the knob and check the result on milk.

Semi-automatic systems (cappuccino)
Pours milk at Trefr. in a container ; with the machine in steam mode:
1.
2.
3.

Open the steam knob to discharge water circuit for 4 sec. then close the knob.
Insert the silicone tube in the milk container, placing a beaker of 250 ml capacity and with
an inner diameter of 70 mm under the cappuccino maker and open the steam knob.
After having provided 100gr. of product, close the knob and check the result obtained on
milk. Note: The same applies to machines which have a steam key on the user interface
and a solenoid valve in place of the steam tap.

Automatic: Carafe, Cappuccino Pinless wonder e.g.:(New Royal, Energica Pure, Intelia
EVO Latte), etc..
After setting the machine to delivery of 100gr. of product:
1.
2.

Launch the “hot milk” function.
Collect the product in a beaker with a 250ml of capacity and with an inner diameter of
70 mm, and verify the result obtained on milk. Carry out the test using milk at a Trefr..

In case the machine allows modify of the emulsion through the menu, use the machine with the
emulsion set to the default value.
Related to the above testing procedure derives the following table of acceptability:
Manual, Semi-Automatic and Automatic’s Milk System

NB: To verify more accurately the height of the cream, a practical expedient dictated by experience is to add to the product just delivered a small amount of coffee. The addition of coffee
immediately put in evidence the surface of separation between liquid and cream.

Functions:
Safety valve: opens towards the drain if the pressure exceeds 16-19 bar
Filling the circuit: the solenoid valve opens (drain position), the pump is controlled and automatically refills the
circuit by expelling the air in the pipe
Draining the unit: before the unit descends, it opens briefly, releasing the pressure created to prevent the unit from
spraying and making the pad drier
Coffee product: when a coffee beverage is selected, the pump is charged briefly during the grinding process and the
valve assumes the drain position for hot water to pass through the pipes.

The coffee grinder is activated by a direct current motor (1) via helicoidal wheel transmission and
a worm screw (2).
The worm screw (2) activates a plastic toothed wheel (3), which turns the lower grinder blade (4)
and the increment pin (5).
There are two magnets (6) in the toothed wheel and with every rotation they transmit two pulses
to a Hall sensor, which in turn transmits them to the electronic system.

04 OPERATING LOGIC

4.10 Auto-learning dose (SAS)
The aim of this function is to automatically regulate the average dose of ground coffee (SELFLEARNING); this takes place with an algorithm based on the following values and setting by the
user:
1. N
umber of coffee grinder pulses during the grinding cycle.
2. M
ax. average value of the power consumed by the gear motor during the coffee brewing cycle.
3. A
roma selected by the user.
The algorithm compares the maximum average value of the power consumed by the gear motor
with the value listed in the table for the selected aroma, in order to calculate the new grinding
pulse value for the next coffee produced.
If the power consumption value is less than the minimum current value, the grinding pulses will
be increased by 2.
If the power consumption value is greater than the maximum current value, the grinding pulses
will be decreased by 4.
If the power consumption value falls within the “over-torque” interval, the product will be dispensed and the grinding pulses will be decreased by 10.
If the power consumption value falls within the “abort cycle” interval, the dreg will be expelled
and the grinding pulses will be decreased by 10.
If the “pre-ground” flavour is selected by the user, no modification will be made.
This guarantees that, regardless of the coffee type used, the grinding level setting
and the wear on the grinders, the ground coffee dose always remains constant.

Important:
For perfect operation, machine adjustment should take place in the area of the fields
highlighted in green (A, B, C). When the type or brand of coffee is changed, there may be
variations in the size of the beans and their stickiness or roasting level. This leads to variations
in power consumption (mA), with resulting excessive or insufficient doses (until the necessary
adjustments have been made to compensate for this change).
Caution: In the case of excessive dosage, powder may be expelled into the dreg
drawer. This is not a fault, but can occur during preliminary operation or after a
service.

4.11. SBS
SBS Principle - Saeco Brewing System
Adjusting the flow speed, which influences the
contact time between the coffee and water,
alters the extraction and therefore the taste
intensity and strength of the coffee.
•
Slower flow: Stronger extraction
•
Faster flow: Lighter extraction
SBS dispensing valve
Turning the SBS adjustment knob will trigger
the brewing process in the coffee unit, where
the flow speed is adjusted via a cream valve.

Cream valve adjustment
Greater flow (light extraction)
If the SBS valve is open, the coffee flows
easily because the pressure is lower and
the membrane remains almost in its base
position with the help of the spring.
The adjustment needle does not close the
opening and the flow does not decrease.

Cream valve adjustment
Slow flow (strong extraction)
The coffee is dispensed slowly with the SBS
valve closed due to the pressure created,
which acts on the membrane and presses it
to the side against the spring force.
Lastly, the valve needle closes the opening,
thereby, reducing the flow.

Function:
The water level is monitored by a capacitive sensor, located one
third up the water tank wall.
If the electronic system detects that the water is below the relative
level by means of the sensor, a water reserve of 200 pulses of the
flow meter remains available for the dispensing process.
The product dispensing process is then completed.
If a dispensing process ends after the sensor has intervened (in the
reserve), the "water absence" signal continues to be displayed as

Function:
The residual water level is monitored by a capacitive
sensor. The sensor is located approximately half way up
the upper edge of the residual drip tray. To make the best
of the tray capacity, the sensor is positioned near a dam
device. In this way, the residual water tray fills up to the
upper edge and overflows inside and when it reaches the
sensor, it triggers the "empty residual water tank" signal.

4.14. AquaClean water filter

The AquaClean filter is designed to reduce limescale deposits in the coffee machine and provide filtered water to preserve the aroma and flavor of each cup of coffee. By using a series of 8 AquaClean filters, there is no need
to descale the machine for 5000 cups (It depends both on the type of coffee used, rinsing and cleaning programs).
We recommend installing the water filter AquaClean the first use of the machine to the maximum before using 5 L of water.
The machine display will indicate when the filter needs to be replaced. The maximum limit is equivalent to 110 L of water.
The conditions related to the filter work environment (water, therefore, an active environment for bacteria and
microorganisms), require the replacement with a minimum frequency (we suggest 3 months from the activation to ensure the best performance). The filter starts’ working from the time is filled with water and continues working even with the machine off. It cannot be deactivated manually, as it must end its life cycle.
At the filter activation the display shows the icon with the percentage of use:
- Initially 100% then decreasing.
When the autonomy of the current filter becomes less than 8 L of water the display shows:
- The icon flashing slowly. It means 10%.
When the autonomy of the current filter becomes less than 2 L of water the display shows
- The icon flashing quickly. It means 0%.
After a maximum of 110 L of water supplied the flashing light turn off and the machine
needs to be descaled.

The submenu “Errors log” is available only if there is at least one error and, If so, it presents the
following information:
- Error code: is the numerical code for the type of fail occurred in the system. For example, “Error
code 15” is the error with index 15 and is equivalent the steam boiler timeout.
- Error index: is the numerical position of the error in the internal list. the maximum number of
items on the list is 20: the list is handled in a circular fashion, that is, the data in the first place is
always the last error occurred in chronological order.
- Error text: is the text description of the type of error that occurred in system. For example:
“Boiler steam out”.
The cancellation of the error list via “Errors reset”, as eliminates all information about them, also
