TALEA / ODEA - LINE 04 FUNCTIONAL PRINCIPLES
Autodose
The appliances are fi tted with an automatic dosage quantity adjustment from the following
software versions:
Type Software version with autodose
Talea Touch ≥ V.01.08.14
Talea Ring Plus / Ring ≥ V.02.00.08
Talea Giro e Odea Giro / Go ≥ V01.02.01
Function:
The coffee machine adjusts automatically the average coffee dose with an algorithm based on
three informations that it detects via the electronic board:
1. Number of grinding pulses performed during the grinding,
2. Maximum of average values of the current consumption of the gear device during the coffee
pressing,
3. Aroma selected by the customer.
The algorithm compares the maximum of the average values of the gear device’s current con-
sumption with the range defi ned to the selected aroma fuction in order to adjust the number of
grinding pulses for the next coffee.
If the value of the current consumption is less than the minimum of the range defi ned for the
aroma in question, the grinding pulses will be increased by 2.
If the value of the current consumption is more than the maximum of the range defi ned for the
aroma in question, the grinding pulses will be decreased by 4.
If the value of the current consumption is within the range defi ned for the “Exceeded stress”,
the coffee will be brewed and the grinding pulses will be decreased by 10.
If the value of the current consumption is within the range defi ned for the “Ejection”, the coffee
cake will be ejected and the grinding pulses will be decreased by 10.
In the customer has selected “coffee powder” as the aroma, no adjustment will be done.
This guarantees that, regardless of the coffee type used, the grinding level setting
or possible wear to the grinding disc always remains constant when dosing.
Important:
The machine monitors in the area of the fi elds shown in green (A,B,C) during normal operation.
This area is normally only left when changing the type of coffee (new bean type / fat content,
new blend). Therefore when changing the type of coffee, a few dispenses may be subject to
under or over dosage (until the controller has compensated for the change).
Caution: In case of overdosage, dry coffee may be ejected several times as a result.
This is not a fault and can occur during fi rst use or after a service.
