2.3.- DOSAGE OPERATION
It is important to remember that the buttons and control units receive signals in the two main switch supply
positions on the machine.
In the fi rst position, the switch will only operate the automatic
water fi lling, but not the heating elements.
In the second position, the switch receives a signal from
the starter relay (optional) and this allows the machine to
be heated and dispense coff ee. It is recommended that this
be done when the machine is hot and the working pressure
in the boiler(s) has been reached, as indicated by the green
range on the gauge (11), and/or shown on the display, if the
machine has one.
2.3.1. Programming dose on the control unit (not available on semi-automatic versions)
In order to program the dose you must press the 'non-stop' button on the left button pad (group 1) for 5 seconds,
and the non-stop coff ee LED will come on (*).
NOTE: If you have already entered programming mode and do not press any button to indicate a dose within
30 seconds, the button pad will go to stand-by position, and the previous step to start programming will have
to be repeated.
At this point programming can be started for the four coff ee selections. When the desired quantity of coff ee is
obtained, press the selection once again and the dosing will stop. The same operation will have to be followed for
all buttons.
By carrying out this process all the groups will be programmed automatically.
The selections that are already programmed will appear with their LEDs off . When this happens it is still possible
to modify the dose in the same manner as indicated above.
If during the dose programming the LED being programmed fl ashes, this means that the fl ow meter is not sending
electrical impulses to the control unit, and they will therefore not form a part of the programming. It is recommended
that the fl ow meters be checked.
