GENERAL DESCRIPTION
The logic board DRF63A allows the complete management of the vending machine (refrigerated or
not) with a maximum of 63 different products.
The same logic board can be used for the entire range of spiral and disc vending machines. It is
necessaty only to select the category of machine in the programming menu (DRX-40/50 for
machines with maximum 63 spirals, DRX-25/30 for all other spiral machines and DFD-3C for disk
machines).
Also available is the operation of the lift system (optional) with programmable levels according to
the tray height.
The logic board allows the possibility to connect all of the most popular payment systems (coin
mechanism. banknotes validator, electronic keys and Executive changers) managing them
contemporaneously allowing also mixed payments.
The keyboard allows the selection of products in the most immediate way; the illuminated, 16
character LCD type display allows the visualizing (in different languages) of the product chosen,
the relative price and the eventual residual money owed for the sale.
All the parameters of work programmed during installation are memorrzed on a EEprom memory
which guarantees integrity even in the most demanding work environs.

FUNCTIONS OF THE DIP-SWITCH
All
parameters of work of the DRF63A logic board are programmable on the EEprom memory
(rvhich is present in the logic board) using the display and keyboard as an interface operator. Only
some options can be selected operating on the 6 way dip-switch DSW1.
The DSV/I dip-switch allows to configure the working conditions of the logic board according to
the followine table:

All dip-switches can be moved while the logic board is working without the necessity to switch off

allows access into the program facilities of the work parameters of the machine
(product prices, credit values of coin mechanism channels etc.).
In the following paragraph, visualization and modifìcation of these parameters will be explained in
detail.
Dip-switch 2 allows the visualization of the total takings from all payment systems present; the
value visualized is expressed in base units, therefore to know the total amount you must multiply
this number by the base unit. To re-set the value of the totalizer press keys "7" arrd "9" of the
keyboard at the same time. By pressing key "1" you can see the the copy of the non re-settable total
takings;pressing key "1" againyou can see the number of sales effected; the value of this totahzer
can be re-set by keys "7" and "9". Pressing again key "1" you can see the copy ofthe nonresettable sales totalizer.
Dip-switch 3 in the ON position allows free sales i.e. the possibility of selling without credit.
Dip-switch 4 in the ON position sets up the automatic re-set of any remaining credit after a fixed
time which can be programmed (10-240").
Dip-switch 5 in the ON position switches off the refrigerator; in absence of the temperature probe it
is necessary to disconnect the refrigerator to avoid a "probe breakdown" signal.
Dip-switch 6 activates the test ptogram of the machine; it is advisable to leave this dip-switch
always in the OFF position.
During the normal use of the machine, the dip-switches 1, 2 and 6 must be kept in the OFF position;
the activation of these will cause the logic board to suspend sales and enter into service mode.

PROGRAMMING OF THE PARAMETERS
For the programming of the work parameters in the EEprom memory it is necess ary to momentarily
move dip-switch 1 into the ON position; thus entering into the facility "programming of
parameters".
The programmable parameters are presented one by one on the display with their current value,
according to a continuous list; to move inside the list and make eventual modifications of the
parameter values, you need to use the keyboard present for sales. Holding pressed down the
relevant keys the values are quickly modified (with linear increasing of speed).
The following table shows the functions carried out by the keyboard in the normal phase of work
(sales) and in the phase of programming the parameters:

RE-SET VALUE
Keys " 1" a1ld "2" allow to move (backwards and forwards) in the opportune parameter of the list,
keys "4" and"5" modify (up/down) the value of the parameter, key "9" re-sets the value of the
parameter, key "7" recalls the value memorized in the previous parameter and finally key "8"
confirms the value.
Attention. changing the value present on the display does not alter the contents of the EEprom
memory; the set value is programmed permanently in the memory only after pressing the
confirmation key "8".
At any time during the phase of modifying parameters it is possible to exit by putting dip-switch I
back to the oFF position: only values confìrmed by key "S" will have changed.

Programming the "Price Holding" option to "Yes" also activates the list of "price lines" associated
with every single product. Be sure to have also programmed the real prices of each product in the
machine and to have imposed the same prices in the EXECUTIVE payment system.
Here follows the list of parameters which can be modified with respective field validity:
o
Product price 11 (0 + 10000 base units)
o
Product price 79 (0 + 10000 base units)

The programming of value 0 as the price of a product excludes same from sales: therefore program
all un-used products at 0. It is also advisable to program to 0 the values of all validator channels not
used.

WHAT TO DO IF...
GENERAL INSTRUCTIONS
. after t.anspoÌt, before switching on the machine, verifo that the flat cable connections are well inserted
. be careful not to mix up the 14 PIN flat cables (one is for the keyboard, the other for &e display)
r clean the outlet of the waste water container at least once a year
REFRtrGERATOR qTOUP
iF THE REFRIGERATOR DOESNT REFRIGERATE:
1. chect< if the compressor, condenser fan {external radiator} and internal fans (black} are working properly
Z. check that the temperature ís prqrammed oroperly (around 14"C)
3. if so, the refrigerator may have lost some gas; in this case, the interventlon of a refrigerator technician
to refill it is sufficient: check the plate that specifies the type of gas used: for the DRF models the gas is
usuaiiy R22 and you will need 3209r for the refili: for the DRX-20i25/30 the gas is R404A and you will
need 2709r for the refill
iF NEITHER THE
1.
FANS NOR THE COMPRESSOR TURN...
check the 6A fuse
iF THE FANS TURN BUT THE COMPRESSOR DOESNT...
1. check the contact relay. Try to jump it to see if the compressor works.
If the compressor and the radiator fan still don't work, it is necessary to check the wiring of connectlons.
IF IT APPEARS'PROBE ERROR''...
1. check if there is a false contact of the probe cables and the logic board. There is rarely a real problem
with the probe.
iF THE INTERNAL FANS DONT WORK...
1. In 7Ao/a of the machines with serial numbers starting with 506rc< to 705rc< (year of construction 19951992) it may be the outlet of the waste water container which ís blocked and the 2 black fans could turn
in the water and be damaged. You should re-open the outlet and enlarge it to a diameter of B mm and
replace the 2 fans.
SPIRAL GEARMOTORS
IF THE GEARMOTOR DOESNT WORK...
1. Check that the flat cable of the tray is not damaged externally (most likely case)
Z. If this is not the problem, you will need to replace the gearmotor
iF NO GEARMOTORS IN THE WHOLE MACHINE WORK, but the rnachine still sells...
L. it means that one of the trays flat cables has a shori circuit on the power supply. You wiil have to
disconnect all the flat cables and re-inseft them one by one until you find the defective one, which is to be
replaced.
MODELS DRX3OI5O LIFT (ONLY THE YERSIQ'.'S WITH LIFT)I

.
.
NECESSARY TO SUBSTITUTE THE GEARMOTOR..,
make sure the gearmotor is 116 cycles;
remove the circuÍt printed LIFT;
uns€rew the supporl stirrup of the "encoder" disc and reffiove Lhe gearmotor;
install the new gearmotor and put everything back together again.
