2.2.1. Specifi cation for the measurement of the coffee products temperature.

The temperature is infl uenced by the fl ow from the dispenser and stratifi 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 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.

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.

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.

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

Coffee Q.ty 70/120 gr.

Temperature of 1st product 69°C ≤ 85°C
Temperature of 2nd product 72°C ≤ 85°C

2.2.2. Specifi 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
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: e.g. Xelsis, Exprelia, Syntia, Intelia.

With milk at Trefr. (about 4-10 °C): ≥ 36

System with Pinless Wonder: New royal, Energica Pure, Intelia EVO Latte.
With milk at Trefr. (about 4-10 °C): ≥ 45

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 (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.

GRAN BARISTO 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. 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 (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 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.

4.2. Coffee cycle

Switching on

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

- It acts on microswitch 1 (see following chapter).

- The gear motor changes its rotation direction and moves upwards again by approx. 1-2 mm.

- The boiler begins to heat the water for approx. 30 sec with controlled power, in order to reach
the optimal temperature. The temperature will then remain at a constant level.

Coffee cycle

1. The grinding process is controlled by time duration in function of coffee strength selected.

2. The gear motor (brewing unit) moves to the brewing position.

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

4. Product dispensing (the pump operation period is defi ned by the amount of product dis-

pensed).

5. The gear motor moves to its home position (the dregs are expelled automatically).

An NTC is used as a temperature sensor; in the event of overheating this reduces boiler element
power consumption.
The electronic system detects the current boiler temperature from the drop in voltage of the
sensor and adjusts it accordingly.

The gear motor is powered by a direct
current motor that engages with the
smaller double toothed wheel using a
worm screw. The unit is mounted on the
axle of the large gear wheel and when
a coffee is requested, it moves from the
standby position to the dispensing posi­tion, and then back to the standby posi­tion again.

- Standby position: 1

- Dispensing position: 2

4.6. Water level detection (water tank)

“Water low” message (water reserve)

Function:

The water level is monitored by a capacitative sensor, located one
third of the way up the water tank wall.
If the electronics assembly detects, by means of the sensor,
that the amount of water in the tank has dropped below the
above mentioned level, a water reserve remains available for
the dispensing process underway (this will cover 200 fl ow meter
pulses).
The product dispensing process will then come to an end.
If a dispensing cycle ends after the sensor has been triggered (in
the reserve) then the display “Water low” continues to be displayed
during the following dispensing cycle.

Detailed description of the diagnosis menu

1. Product counters
“Product counters” represents the total number of deliveries performed by the machine for

each product from the production.

2. Error counters
“Error counters” displays the total number of errors “out of service” (fail) occurred in the system

(see “Errors log”), and allows you to reset the drive (see “Errors reset”).
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, submit the fol­lowing information:

Error code: is the numerical code for the type of fail has occurred in the system. For example,
“Error code E01” is the error with index 1 and is equivalent to the Grinder blocked.

Error index: represents the numeric position of the error in the internal list.
The maximum number of elements in the list is 20: the list is handled in a circular fashion, that
is, the data in the fi rst position is always the last error that occurred in order of time (eg 01/07
means that you are reading the most recent error on a total of 7 errors).

Error text: is the text description of the type of error that occurred in the system.
For example: “Grinder blocked.”

The cancellation of the error list by “Errors reset”, as it deletes all information relating thereto,
also prevents access to the menu under “Errors log”.

List of possible errors of “out of service”:

Grinder blocked (E01): occurs if the grinder is to have the mills blocked.
In this case, the machine stops the instant the user asks for the machine to dispense a drink
made of coffee (just coffee beans).

Brewing unit blocked work (E03): occurs when the brew unit can not move from location to
location work home.

Brewing unit blocked home (E04): occurs when the brew unit can not move from the home
position to the work position.

Water circuit interrupted (E05): occurs when the fl ow meter is faulty, disconnected or does
not occur passage of water. In these cases, since the machine fails to correctly read the pulses
of water, enters alarm condition “CHARGING CIRCUIT” in the moment in which the user asks to
dispense a product:
if the “charging circuit” the machine supply fails block.This total.

DC Valve short circuit (E06): occurs when one of the valves of the fl ute is short-circuited.
This problem may occur during the delivery of a product based on milk.

Coffee temp. sensor short circuit (E10): occurs when the temperature of the coffee boiler
sensor is short-circuited. This error causes a total shutdown of the machine to start up.

Coffee temp. sensor open circuit (E11): occurs when the temperature of the coffee boiler
sensor is not detected. The problem is due to the absence of the signal of the sensor and does not
allow the machine to establish the actual temperature of the coffee boiler.
At start up, the machine enters the halt.

Boiler coffee timeout (E14): occurs when no power coming to the coffee boiler, this does not
reach the preset temperature within a time of 2 minutes.
At start up the machine remains long in the screen WAITING READY TEMPERATURE, with the
message “Warming up ...”, and after the expiry of the time goes to lock out.

Zero crossing error (E19): occurs when the machine does not detect the signal zero
crossing.

Coffee boiler overheating (E20): occurs when the temperature of the coffee boiler and ex­ceeds 170 ° C.

BU encoder error (E24): occurs when the machine is not correctly detect the signal of the en­coder

3. Water counters

“Water counters” shows water consumption (in liters) following delivery of products, the desca-

ling cycle, the cleaning cycle the activation group and fi lter.

The submenu “Descaling cycle” has the following items:
Liters since last: represents the total number of gallons of water consumed since the last descaling
cycle. It is reset after the complete execution of the descaling cycle.

Excess liters since last: represents the number of liters of water consumed in excess since the
car signals the descaling indicator.
It is reset after the complete execution of the descaling cycle.

Liters last descale: represents the total number of gallons of water consumed until the last de­scaling cycle.
Takes the value of “Liters since last” after the complete execution of the descaling cycle.

Excess liters last descale: represents the number of liters of water consumed in excess since
the car reported the descaling indicator until the last descaling cycle.
Takes the value of “Excess liters since last” after the complete execution of the descaling cycle.

Number of execution: represents the number of cycles executed on the machine descaling.

The sub-menu “Brewing unit cleaning” has the following items:

16

GRAN BARISTO 05 TROUBLESHOOTING

Page / 18

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

Liters since last clean: represents the total number of gallons of water consumed since the last
cleaning cycle group. It is reset after the execution of a complete cleaning cycle group

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

Since last reset: represents the total number of gallons of water from the last cycle of activation
fi lter.
It is reset after the execution of the cycle of activation fi lter.

Number of reset: represents the number of cycles performed activation fi lter on the machine

The item “Since production” has the following items:

Liters Coffee / Water represents the total number of liters of water consumed during the exe­cution of coffee products (or the mixed coffee) or water.

Liters Steam represents the total number of liters of water consumed during the execution of
milk products (milk or mixed part).

4. Grinding auto dose

The submenu “Grinding timer” indicates for each fl avor (Dose 1 Dose ... 6) the grinding time in
msecs.
These values evolve over time depending on the technique of ‘autodose.

The submenu “Encoding strength” indicates the multiplicative constants used to calculate the
expected volume of each fl avor (multiplicative constant * gr = number of encoder pulses relative
to the volume of the aroma: es: aroma 1 -> 44 * 5 = 220).

The submenu “Bean lack alarm” indicates for each fl avor the minimum number of encoder pul-
ses (volume of the pad) that allows you to not give the alarm without coffee.

The submenu “Dregdrawer alarm” has the following items:

“Dreg alarm”: indicates the value at which the counter is reset funds to indicate the alarm funds.

“Dreg counter” represents funds that the counter is initialized to the value of “Dreg alarm” to

any empty the drawer bottoms and decremented by a value depending on the dose in the ground
made products. When is 0 the machine will display the alarm drain funds.
