Page 11: Specification For The Measurement Of The Milk Products
XSMALL 02 TECHNICAL SPECIFICATIONS 2.3.1. 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 refrige- rator 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. - Page 12 XSMALL 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: 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: 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.

Page 28: Single Microswitch
XSMALL 04 OPERATING LOGIC 4.4. Single microswitch The gear motor is powered by a direct cur- rent 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 home position to the dis- pensing position, and then back to the home position again. - Home position: - Dispensing position: 4.5. Temperature sensor (adjustment) Temperature sensor An NTC is used as a temperature sensor; in the event of overheating this reduces boiler ele- ment power consumption. -
Page 29: Low Bean Level Detection, Dose Quantity Adjus Tment
XSMALL 04 OPERATING LOGIC 4.6. Coffee grinder function Ceramic coffee grinder 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 transmit two pulses to a Hall sensor, which in turn transmits them to the electronic system. 4.7. Low bean level detection, dose quantity adjustment, coffee grinder blocked No coffee Without beans n=100% 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 With beans n=100%... -
Page 30: Dose Self-Learning
XSMALL 04 OPERATING LOGIC Dose self-learning (SAS) The aim of this function is to automatically regulate the average dose of ground coffee (SELF- LEARNING); this takes place with an algorithm based on the following values and setting by the user: 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 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” 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. - Page 31 CHAPTER 5 SERVICE MODE...
