2.2. 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

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. 45 sec., at full power, in order to reach the optimal temperature. The temperature will then remain at a constant level.

Coffee cycle

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

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. Heating element values and corresponding temperatures: see table.

4.3. Single microswitch

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.

4.6. Low bean level detection, dose quantity adjustment, coffee grinder blocked

Without beans n=100%

With beans n=100%

Without beans n=50%

With beans n=50%

The coffee grinder is driven by a direct current motor (1) using a worm screw helicoidal wheel transmission (2). The worm screw (2) drives a plastic gear wheel (3), which turns the lower grinder (4) and the increment pin (5) There are two magnets (6) in the gear wheel; at every rotation these induce two pulses to a Hall sensor, which in turn transmits them to the electronic system.

No coffee

A low coffee bean level is detected by the Hall sensor, after variations in the pulse frequency (with or without coffee). If there are no coffee beans (operation while empty), the number of rotations – and therefore the number of pulses – will be greater.

t1 = no coffee indication

If, however, there are coffee beans, the number of rotations will be lower due to the force created by the grinding.

t2 = no indication

t3 and t4 = this measurement is performed at the end

of each grinding process

Dose quantity adjustment

The dose quantity is adjusted in accordance with the pulses detected (number of rotations proportional to the

selected ﬂ avor – mild, medium or strong).

Coffee grinder blockage

If the coffee grinder becomes blocked for any reason, pulses will no longer be transmitted to the electronic system and the grinder will come to a stop.

4.7. Dose self-learning (SAS)

06

The aim of this function is to automatically regulate the average dose of ground coffee (SELFLEARNING); this takes place with an algorithm based on three pieces of data that the machine receives via the card:

1. Number of coffee grinder pulses during the grinding cycle.

2. Max. average value of the power consumed by the gear motor during the coffee 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 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” ﬂ avour is selected by the user, no modiﬁ cation 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 ﬁ elds 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 insufﬁ 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.

4.8. 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.

If the function is turned on the electronics assembly monitors the ﬂ ow meter pulses, recording one pulse every two turns.

“Change water ﬁ lter” message

The electronics assembly uses the ﬂ ow meter impulses to keep track of the amount of water which has ﬂ owed through; after the speciﬁ ed amount (set in accordance with the water hardness level), the “Replace ﬁ lter” message appears.

When the machine is switched on the procedure starts; the display changes to yellow and the word “ON” indicates that the procedure is running. During the procedure the 2-way solenoid valve remains open and the steam is discharged.

Caution!!! If the dreg drawer is not fully in, the machine will ask you to insert it, this must be done otherwise the 2- and 3-way solenoid valves are not powered.

Caution!!! If the side hatch opens, the machine warns you to close it, the hatch must be closed otherwise the 2- and 3-way solenoid valves will not be powered.

When the procedure is completed, the message “COMPLETE” appears on the display, the solenoid valves close automatically and the machine may be switched off.
