2.3.1. Specication for the measurement of the coee products temperature.

The temperature is inuenced by the ow from the dispenser and stratication 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 coee machine is tested without any change of parameters or calibrations, which may

aect 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 rota-

tions, 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 coee dis-

pensed: 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 Coee 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. Specication 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 pa-

rameters, 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 rst 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 oscil-

late.

GAGGIA BABILA 02 TECHNICAL SPECIFICATIONS

6/6

How to measure the milk cream.

The temperature (Trefr or Tamb) of the milk doesn’t aect 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. Open the steam knob to discharger water circuit for 4 sec, then close the knob.

2. Place the beaker with the frother dipped in milk, open the steam knob to maximum and

start the chronometer.

3. 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. Open the steam knob to discharge water circuit for 4 sec. then close the knob.

2. 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.

3. 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. Launch the “hot milk” function.

2. 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

Grams of Product Minimun Height of the milk cream

≥ 130 ≥ 30mm

120 ≥ 25mm

110 ≥ 22mm

100 ≥ 20mm

90 ≥ 16mm

80 ≥ 13mm

70 ≥ 11mm

NB: To verify more accurately the height of the cream, a practical expedient dictated by expe-

rience is to add to the product just delivered a small amount of coee. The addition of coee

immediately put in evidence the surface of separation between liquid and cream.

Drain to the drip tray

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 rells the

circuit by expelling the air in the pipe

Draining the unit: before the unit descends, it opens briey, releasing the pressure created to prevent the unit from

spraying and making the pad drier

Coee product: when a coee beverage is selected, the pump is charged briey during the grinding process and the

valve assumes the drain position for hot water to pass through the pipes.

4.5. Coee cycle

Switching on

When the machine is switched on, the gearmotor repositions itself as follows:

- It stresses microswitch 1 (see the following chapter)

- The gearmotor changes the rotation direction and moves upwards again by approx. 1-2 mm

- The boiler begins to heat the water for approx. 45 sec. at full power in order to

reach the optimal temperature. The temperature will then remain constant.

Coee cycle

1. The coee grinder starts the grinding process (controlled by pulses generated by a sensor)

2. The gearmotor (coee unit) moves to the dispensing position

3. Preliminary dispensing phase (short pump activity, short pause)

4. The product is dispensed (the pump operation time depends on the amount of product

dispensed)

5. The gearmotor moves to the idle position (the dregs are expelled automatically)

With beans n=50%

The coee 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.

No coee

When no coee beans are present, this is detected by the Hall

sensor due to variations in the pulse frequency (with or without

coee).

If there are no coee beans (operation while empty), the number

of rotations and therefore the number of pulses, will be greater

t1 = no coee signal

If there are coee beans, the number of rotations will be

lower due to the force created during the grinding process

t2 = no signal

t3 and t4 = this reading is taken

Dose quantity adjustment

The dose quantity is adjusted in accordance with the pulses

detected

(number of rotations proportional to the weak, medium and

strong avour selection)

If the coee grinder is blocked for any reason, pulses will no

longer be transmitted to the electronic system and the grinder

4.10 Auto-learning dose (SAS)

The aim of this function is to automatically regulate the average dose of ground coee (SELF-

LEARNING); this takes place with an algorithm based on the following values and setting by the

user:

1. Number of coee grinder pulses during the grinding cycle.

2. Max. average value of the power consumed by the gear motor during the coee brewing cycle.

3. Aroma 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 coee 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 dis-

pensed 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” avour is selected by the user, no modication will be made.

This guarantees that, regardless of the coee type used, the grinding level setting

and the wear on the grinders, the ground coee dose always remains constant.

Important:

For perfect operation, machine adjustment should take place in the area of the elds

highlighted in green (A, B, C). When the type or brand of coee 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 insucient 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.

SBS Principle - Saeco Brewing System

Adjusting the ow speed, which inuences the

contact time between the coee and water,

alters the extraction and therefore the taste

intensity and strength of the coee.

• Slower ow: Stronger extraction

• Faster ow: Lighter extraction

SBS dispensing valve

Turning the SBS adjustment knob will trigger

the brewing process in the coee unit, where

the ow speed is adjusted via a cream valve.

Cream valve adjustment

Greater ow (light extraction)

If the SBS valve is open, the coee ows

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 ow does not decrease.

Cream valve adjustment

Slow ow (strong extraction)

The coee 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 ow.

Empty residual water tank signal

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 lls up to the

upper edge and overows inside and when it reaches the

sensor, it triggers the "empty residual water tank" signal.

Water absence signal (water reserve)

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

ow 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

e AquaClean lter is designed to reduce limescale deposits in the coee machine and provide ltered wa-

ter to preserve the aroma and avor of each cup of coee. By using a series of 8 AquaClean lters, there is no need

to descale the machine for 5000 cups (It depends both on the type of coee used, rinsing and cleaning programs).

We recommend installing the water lter AquaClean the rst use of the machine to the maximum before using 5 L of water.

e machine display will indicate when the lter needs to be replaced. e maximum limit is equivalent to 110 L of water.

e conditions related to the lter work environment (water, therefore, an active environment for bacteria and

microorganisms), require the replacement with a minimum frequency (we suggest 3 months from the acti-

vation to ensure the best performance). e lter starts’ working from the time is lled with water and con-

tinues working even with the machine o. It cannot be deactivated manually, as it must end its life cycle.

At the lter activation the display shows the icon with the percentage of use:

- Initially 100% then decreasing.

When the autonomy of the current lter becomes less than 8 L of water the display shows:

- e icon ashing slowly. It means 10%.

When the autonomy of the current lter becomes less than 2 L of water the display shows

- e icon ashing quickly. It means 0%.

The maximum number of “Fail” count is 20.

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 rst 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

prevents access to the submenu “Errors log”.

product: if the “charging circuit” fails C.A. blocked.

DC Valve short circuit: occurs when one of the valves of the ute is shorted circuit. Such a

problem may occur during dispensing of a product based on milk.

Coee temp. sensor short circuit: occurs when the temperature sensor coee boiler is shor-

ted. This error causes a blocking in C.A. to start-up.

Coee temp. sensor open circuit: occurs when the temperature sensor coee boiler is not

detected. The problem is due to the absence of the signal of the sensor and does not allow to

determine the C.A. the actual temperature of the boiler coee. At start up, the C.A. blocked.

Steam temp. sensor open circuit: occurs when the temperature sensor steam boiler is not

detected. The problem is due to the absence of the signal of the sensor and does not allow to

determine the C.A. the actual temperature of the boiler steam. At start up, the C.A. blocked.

Steam temp. sensor short circuit: occurs when the temperature sensor boiler steam is shor-

ted. This error causes a blocking in C.A. to start-up.

Water counters

“Water counters” shows the consumption of water (in pulses) following the granting of

products, to the descaling cycle, cleaning cycle, the activation group and lter.

The submenu “Descaling cycle” has the following items:

Since last cycle: is the consumption of water after the last cycle descaling.

Since second last: it represents the consumption of water after the penultimate cycle desca-

ling. Since last second takes the value of Since last after full implementation of a descaling cycle,

whereas Since last becomes 0.

Since third last: it represents the consumption of water after the antepenultimate cycle desca-

ling. Since last third has the value of Since last second after full implementation of a descaling

cycle

Number of execution: represents the number of cycles of decalcication performed on C.A .

The submenu “Brewing unit cleaning ‘has the following items:

Since last: it represents the consumption of water after the last cleaning cycle group. Since last

assumes the value 0 after the complete execution of the cycle cleaning group.

Number of execution: represents the number of cleaning cycles performed group on C.A .

The submenu “Water lter” has the following items:

Current Number: Current Number: current number of lter within the process chain longevity. It

can range from 0 to 8.

Remain. Cc to expire: Autonomy of the lter, so the amount of water in cc remaining before

the expiry of the lter.

Total Filter used: total number of lters turned on the machine

Total water cc: total amount of water, in cc, which has gone through the machine with active

lters and unexpired.

Remain. Cc startup: counter of the remaining water, expressed in cc, for the activation of the

rst lter of the chain (1/8) . It goes from 5000 to zero: the rst lter must be activated before

the counter reaches zero, otherwise it will be necessary to descale before activating the lter.

The item “Water since production” represents the total water consumption, expressed in

pulses turbine.

Max grinder dose

The item “Max grinder dose” allows you to select the maximum threshold value dose that can

take on the grinder. The range of variation of the chosen threshold can vary from 100 to 170.

Max ground

The item “Max ground” allows you to select the maximum number of coee grounds.
