3.9. Dose self-learning (SAS) 120-127V
The aim of this function is to automatically regulate the average dose of ground coee (SELF-LEARNING);
this takes place with an algorithm based on the following values and setting by the user:
1. Number of coee grinder pulses during the grinding cycle.
2. Max. average value of the power consumed by the gear motor during the coee brewing cycle.
3. Aroma selected by the user.
e 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
coee produced.
If the power consumption value is less than the minimum current value, the grinding pulses will be in-
creased by 2.
If the power consumption value is greater than the maximum current value, the grinding pulses will be de-
creased 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” avour is selected by the user, no modication will be made.
is guarantees that, regardless of the coee type used, the grinding level setting and the wear on the
grinders, the ground coee dose always remains constant.
Important:
For perfect operation, machine adjustment should take place in the area of the elds highlighted in green
(A, B, C). When the type or brand of coee is changed, there may be variations in the size of the beans
and their stickiness or roasting level. is leads to variations in power consumption (mA), with resulting
excessive or insu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. is is not a fault, but
can occur during preliminary operation or aer a service.
