3.6.2. Dose self-learning (SAS)
e aim of this function is to automatically regulate the average dose of ground coee (SELF-LEARNING); this
takes place with an algorithm based on the following values and setting by the user:
1. Number of coee grinder pulses during the grinding cycle.
2. Max. average value of the power consumed by the gear motor during the coee 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 coee
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 (800≤ MAX_CURRENT_mA ≤1000),
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 (MAX_CURRENT_mA>1000), 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 modication will be made.
This guarantees that, regardless of the coee type used, the grinding level setting and the wear on the
grinders, the ground coee 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 coee 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
insucient 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 rst usage or after repair.
