regulaTion of grinding wheels
Use this group of functions to check the parameters in-
tended to regulate the distance between grinding wheels
automatically and to enable or disable the function on
the grinders complete with an automatic regulation
device.
In particular, you can choose on which grinder - identi-
ed by a number - to act. After you have made your
choice, the leds of the selection of reference corre-
sponding to that grinder will turn on.
auTomaTic regulaTion enaBle
For each grinder you can decide whether to let the auto-
matic regulation device work or not.
auTomaTic regulaTion parameTers
For each selection of reference, please program:
- The water dose (expressed in volumetric counter
pulses -cdv-)
- The brewing time (expressed in sec.)
- The manual regulation of the distance of grinding
wheels; any variation will correspond to about 1/6 of a
turn of the regulation ring nut. Positive values reduce
granulometry (finer grinding), negative values increase
it (coarser grinding).
new grinding wheels
This function is intended to reset the times stored with
reference to the grinding wheel wear; in particular, the
average initial grinding time stored during the rst selec-
tions and used to establish when grinding wheels are
worn (the grinding time is over 50% longer than the initial
time).
grinding wheel TesT
Use this function after having replaced the grinding
wheels or the grinder.
The test shall be carried out without coee.
- If you confirm the test, grinding wheels rotate and come
close to each other to touch;
- the machine will stop, waiting for confirmation;
- if you confirm once again, grinding wheels depart and
rotate the grinding wheel ring nut by some turns;
- the machine will stop, waiting for confirmation;
- if you pour coffee and dispense some selections of
reference, grinding will automatically become stable
auToTesT
Function used to check the operation of the main com-
ponents of the machine semiautomatically. Press the
Enter key to display the “AUTOTEST” message ashing
on and o.
You can renounce any operation and move to the next
one by pressing the exit key. If you conrm by press-
ing the enter key, you will start the autotest cycle. Some
controls occur automatically. Others require the manual
operation of the component under control.

- operating whipper motors for 2 seconds at the various
speeds
- dispensing a cup

number of the button you shall press, turn on the rela-
tive led and wait for its operation before moving to the
next key
- checking the operation of the boiler temperature probe
- checking the operation of the sound signaller (buzzer)
- checking the operation of the coin mechanism
- checking the grinding wheels (only grinding with au-
tomatic regulation); the machine tightens the grinding
wheels to build up a pack up to the maximum closing
point and opens them by 5 turns upon confirmation
- aspirator management; the machine powers on and off
the powder suction fan wheel
- checking the “open door micro” operation: the machine
will remain in standby mode until you operate the “open
door micro”.
Operate the “open door micro” by turning the lock key.
