Grinders – grinding degree and motor cooling
The grinders have been set to a default value at the factory and must be set
up for the customer-specific types of bean and beverages during
commissioning of the machine.
See attachment Schaerer Barista - Basic beverage settings
With specially hardened grinder disks and the powerful grinder motor, these
grinders can achieve a very fine grinding degree, with a grain size distribution
down to a minimum of 190 µm.
Important technical service instructions
Factory settings:
Grinding degree 3 -> approx.: 1.6 g/s and a grain size distribution of about 280 µm
o Due to the fine grinding degrees and the longer grinding time, it is necessary to actively cool down the motor
o The two installed fans perform the function of motor cooling and cool the bean hopper as well
Grinders – idle current calibration
Menu -> Service -> Service routines -> Idle current
calibration starting for Grinder 1 or Grinder 2.
Follow the animation - lock the bean hopper (see left illustration) and
measure the idle current. After successfully carrying out the idle current,
open the bean hopper again and dispense a test beverage in order to fill the
grinder.
