INCANTO 04 OPERATING LOGIC
5/10
When the coffee grinder is working, the software monitors the current consumption. If the current
value is very low, the machine concludes that coffee is missing; if the current value is very high, the
machine concludes that the coffee grinder is blocked; instead, if the current value is in the middle,
the machine concludes that all is ok and it goes on to do the product.
Because the current consumption of grinder changes depending on the situations (motor new or
old, cold or hot, etc., coffee blends), these current thresholds are not static, but dynamic.
1) When the system get the stability (i.e. the system got the current target) the coffee doses
should be:
A1 A2/3 A4/5
7,5 9,0 10 ±1,5 grams
with medium grinding (500±60μm) and using coffee of test.
2) the 3 grinding times are always:
T
1
<T
2
<T

beside, every grinding time is, respectively:
4,0s ≤ T
3
≤10s (10000ms)
3,5s ≤ T
2
≤9s (9000ms)
3,0s ≤ T

≤8,1s (8100ms)
