SYNTIA CAPPUCCINO 4.5. 04 OPERATING LOGIC Single microswitch The gearmotor is activated by a direct current motor that acts on the smaller double toothed wheel via a worm screw. The unit is mounted on the axle of the large toothed wheel and when a coffee is requested, it moves from the idle position to the dispensing position to then return to the idle position. 2 - Idle position: 1 - Dispensing position: 2 1 4.6.

SYNTIA CAPPUCCINO 4.7. 04 OPERATING LOGIC Coffee grinder 5 6 4 1 2 3 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. 4.8.
SYNTIA CAPPUCCINO 4.9 04 OPERATING LOGIC Auto-learning dose (SAS) The aim of this function is to automatically adjust the average dose of ground coffee (AUTOLEARNING); this occurs by means of an algorithm based on three pieces of information detected by the appliance board: 1. Number of coffee grinder pulses during the grinding cycle 2. Max average value of the power consumed by the gearmotor during the coffee brewing cycle 3.
SYNTIA CAPPUCCINO 04 OPERATING LOGIC 4.10. Water level detection (water tank) Water absence indication (water reserve) Water tank Sensor 200 puls. 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.

Descaling request Flow meter pulses Descaling indication with anti-scale filter (only in appliances equipped with a display) The water hardness is set on the basis of the regional water hardness analysis (1, 2, 3, 4). Enabled filter Disabled filter: If the function is disabled, the electronic system counts the flow meter pulses, recording one pulse for every revolution.
