PROGRAMMING COFFEE DOSES
The quantities relating to the volumetric coffee doses can be modified and stored by following the procedure
set out below
In IDlE-ON status, press the
K5gRx (1..3)
key and keep pressing it for 5 seconds; make sure that the
lighting of the lEDs
l5gRx (1..3)
switches from fixed to flashing.
K5GRx
PRess KeY > 5 seconds
The display shows
Doses setting
Select within30s
Within 30 seconds (time-out to quit the programming phase), press any of the keys combined with the 4
doses which can be programmed (for example K1GRx). The lEDs will always stay on. The lED relating to
the key being programmed will flash until the dynamic programming is complete.
K1GRx
When the quantity of coffee with which the dose is to be programmed is achieved, press the key being
programmed to interrupt product dispensing with the consequent de-energising of EVx + PUMP. The new
value of the espresso dose is stored in EEPROM in pulses of the volumetric meter.

To proceed with programming the remaining coffee doses (if the programming time-out of 30 sec-
onds is not exceeded), repeat in sequence points
and
.
•
if the time-out (30 seconds) is triggered during the programming phase, to proceed with its per-
formance, you will need to repeat the entire sequence described in points
