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 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 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" 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.
Setting/Status
A Mild aroma
B Medium Aroma
C Strong Aroma
D Over-limit
E Overwork
F Dreg expulsion
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.
