CONTROLS AND INFORMATION

The machine can be used only as slave, therefore the
control functions are handled by the master machine.
The main switch, which is of the manual type, disconnects
the machine in the event of maintenance operations.
The information for the user (sales price and selection
number) is indicated on self-adhesive labels to be placed
in front of the spirals during installation.

INTERNAL COMPONENTS

The evaporator assembly mounted on the cabinet shelf
comprises two fans, the evaporator, the air duct and a
water retaining tray placed under the evaporator.
The C.P.U. board (central processing unit) located in the
lower right section inside the vending machine controls
the different functions and communicates with the C.P.U.
board of the master machine.

The cooling unit is located in the lower part of the cabinet.
When removing the cover of the last ventilation grille (see
Fig. 17) the air circulation ensures a uniform temperature
inside the refrigerated box, between 9°C and 12°C.
When covering the ventilation grille, the temperature
inside the refrigerated box is differentiated between the
upper three trays (12°-16°C) and the lower three trays (8°-
10°C).
The cooling unit is defrosted automatically every 6 hours.
However, the timing is programmable.
The power supply unit, mounted in the lower section of the
cabinet, contains the relay card which activates the com-
pressor, the protection fuses, the main switch, the trans-
former and the C.P.U. board.

MAIN SWITCH

The power supply unit (see Fig. 27) is fitted with a manual
switch that disconnects the power from the machine
electrical system,

except from the terminal board supporting the line
cable, the line fuses and from the same switch area.

Before removing the cover from these parts (indicated
with a specific plate) it is necessary to disconnect the
external switch.

All operations which require the machine to be ener-
gised with the door open must be carried out by
qualified personnel who are aware of the specific risks
of such condition.

BANK CONFIGURATION

The machines are initially configured for operation in a
bank of machines, therefore the software must be set for
the necessary options.
After completing the connection between the machines
and to the power supply, switch on only the master
machine.
Access the master/slave function in the technician menu
and select the type of slave to define the number of digits
indicating the selection.
Two digits (XX) are advisable if the bank has only one
machine with numeric selection.
If there are two slaves, it is advisable to use three digits
(0XX, 9XX) for identifying the selection groups.
When switching on the slave regarding the choice made,
the master will communicate if the procedure was suc-
cessful.
If necessary, repeat the procedure to configure the sec-
ond slave, making sure not to configure two slaves the
same way.
The configuration must be defined every time the master
machine is initialised.
Should the configuration of a slave need to be changed,
access the master function that indicates the switched on
slaves as not configured.
After the configuration, it will be possible to access the
filler and technician menus of the slave from the master
machine.
When pressing the programming button on the master,
the software will ask the user to select the type of vending
machine to be accessed.
