C.P.C. devices (BDV only)
It dialogues with the coin mechanism if devices are in-
stalled or removed from the serial interface (C.P.C.-type
devices - the monitoring unit is always enabled by default).
Minimum level of tubes
It brings forward the “Insert exact amount” message for the
user, by adding a number of coins between 0 and 15 to the
programmed number of coins, to set the “full change tubes”
status.
Free Vend (BDV only)
Most payment systems with the BDV protocol control the
free vend function.
However, there are some payment systems without such
function.
In this case, if free selections are to be dispensed, free
vending must be enabled with VMC (vending machine
control, disabled by default) and the price of the selections
must be set to zero.
COMMON FUNCTIONS
IMMEDIATE CHANGE

cash message is sent at the beginning of dispensing.

decimal point, i.e.:
0 decimal point disabled

and can then be modified as necessary.
SELECTIONS
The selection menu is composed of various sub-menus
which allow setting of the different parameters.
WATER DOSE
The water dose, expressed in cc, can be set for each
selection button and therefore each product assigned to it;
the display indicates the name of the product being se-
lected.
It is also possible to set the water flow rate of the single
solenoid valves expressed in cc/s (the default value setting
in cc/s is indicated in the selection dose table) to calculate
the amount of water to be dispensed.
WHIPPER CONTROL
The whipping duration can be set for each selection button
and therefore for each water dose composing the selec-
tion.
The duration can be set in two main modes:
absolute
that is, independently from the solenoid valve opening
time. The whipping duration is set in tenths of a second for
the instant models and volumetric counter pulses for the
Espresso models.
relative
that is, as the difference, more or less, from the moment
of closing the solenoid valve.
The whipping duration is always expressed in tenths of a
second.
POWDER DOSE
The powder dose, expressed in grams, can be set for each
selection button and therefore each product assigned to it;
the display indicates the name of the product being se-
lected.
For correct conversion of product dose values, the flow rate
of the single dosing units, expressed in g/s, can be set to
calculate the amount of powder to be dispensed.
It also possible to program the doses of a product “Glo-
bally”, i.e. setting all selections with a single operation.
ACCESSORIES
Dispensing of sugar, stirrer and cup can be enabled or
disabled for each single selection button.
SELECTION STATUS
Each single selection button can either be enabled or
disabled.
BUTTON-SELECTION
This function is used to associate a selection number,
indicated in the selection dose table, to a direct selection
button.
CHECKING THE SELECTION N.
This function is used to check the selection number (for
direct selection models) assigned to a button.
