2 - ELECTRICAL SYSTEMS - CONNECTIONS - CONFIGURATIONS

The machine is designed to operate under a single-phase voltage of 230 V AC (+5-10V)
It is protected with two T 6,3 A fuses on both phases.
A safety transformer supplies power to very-low voltage components (24 V DC), while the cooling unit and
the Flourescent lamp are powered with the mains voltage.
With regard to the safety transformer:
The primary winding is protected with a T 800 mA fuse
The secondary winding 25 V is protected with the following fuses:: T 1 A – T 4 A

The slide-out compartment door is fitted with a bipolar safety switch.
The switch is located on the front panel of the power supply unit, and when opening the compartment it
disconnects the power from all parts that can be accessed for normal maintenance and cleaning operations.
The only parts that stay energised are those protected by suitable covers carrying a plate with the warning
"Disconnect power before removing the cover”; to clear the voltage the power the power supply cable
must be disconnected from power outlet

or in the case of connection to a dedicated power board, it should

be set to OFF

The power cable can be supplied as standard feature and chosen
among the following types:
HO5 RN – F copper with a 3 x 1.5 mm

2

section

1) HO5 VV – F ,, ,, ,, ,,

2) HO7 RN – F ,, ,, ,, ,,
In all configurations the cable is fitted with a SCHUKO plug
permanently fixed to the cable

NOTE :

In the event of replacement cables of exactly the same
characteristics must be used.
Since the “SFERA” vending machine is approved by an
electrical safety certification institute (IMQ), replacements
with non-original components are not permitted.
Otherwise the electrical safety certificate and the warranty will
be void.

ACTUATION BOARD AND CONNECTIONS

(Electrical compartment open)

A

flourescente lamp is located vertically on the right­hand side inside the cabinet; the starter is fitted
inside the lamp holder. (see page 12)
The ballast is located inside the power supply
compartment.
The CPU board controls also the 24 V actuations by
means of TRIACs and Darlington switches, while the
lamp and the cooling unit are controlled by a relay
card located inside the power supply compartment.
(see page 12)
Some versions are provided with monitoring of the
selected product fall into the dispensing
compartment by means of a card with
receiver/transmitter diodes (infrared).
If during a selection the barrier is not interrupted it
means that a product is finished or jammed, in this
case the system will further attempt releasing the
product with small rotations; if also this fails the
selection is disabled and the customer is entitled to a
new selection.

3 – VENDING SYSTEMS

“Sfera” is

a vending machine belonging to the S&F range, with
product dispensing by means of the rotation of spirals.
During their rotation the steel spirals, because of their “auger
effect”, push forward the product loaded onto the tray,
dropping it in the dispensing compartment.

A

s an optional kit on request, some versions are provided with
infrared barriers with receiver/transmitter diodes and transistors
that detect the falling product and signal to the software that
the product was released correctly. In the event the barrier is
not interrupted, the option of trying the selection again is given;
if the selection fails again, the option of another choice or
refund is given. (SW option)
The tray is modular, and by simply moving the partitions it is
possible to change it from single to double or triple; there are
also some specific accessories for dispensing special products.
Different pitch spirals are provided, to be able to dispense 20 to
76 mm wide products.
In addition the spirals can be right or left hand, to be used in
double compartment configuration with double spiral. The
ratiomotor is fitted with a “minidip” switch to reverse the
rotation.
The tray is held into position automatically by a stop located on
the guides; to slide out the tray it need to be lifted slightly from
the front and then pulled fully to the second safety stop. To
extract it completely it needs to be lifted further and then
removed (after disconnecting the electrical connector located on
the right side). As standard feature, the vending machine is
provided with 6 trays, however up to 8 trays can be fitted by
reducing the space between trays
(see configuration instructions).

machine is type-approved (or awaiting approval) by IMQ,
therefore all components and electric units are certified as
conforming to European directives, and all cables are fully
sheathed and provided with double insulation. The door
cables are sectioned and fitted with special connectors to
facilitate disassembly of the door.

A

ll connectors for the vending machine control function
branch out from the power supply unit: Keypads, payment
systems, ratiomotors, heating elements, display, cooling
units, electronic cards.

T

he power supply unit transforms the grid electricity to 24 V

A

C and the CPU board acts as rectifier and controller of
actuations to the power users.

his way the software controls the unit switching on and

off with extreme accuracy.

T

he unit is controlled by means of a relay card located in
the power supply unit (SOR card).
When the machine is switched on, the software reads the
value (in Ohm) from the NTC probe and, according to that
value, sends a signal to the relay card that activates o

r

deactivates the cooling unit operation.
The cooling unit is very compact, with the air intake for the
condenser cooling from the lower part of the base through
a filter that removes the dust; such filter is accessible and
easy to remove for cleaning FIG. 2.

T

he cooling air is
expelled from the front side through the lower grille,
allowing installation in a bank of machines or in a small
space without causing problems to the cooling unit.
In order to completely remove the cooling unit the
dispensing compartment assembly has to be removed
(quick and simple operation), therefore remove the
fastening screws from the unit and support the evaporato

r

during the extraction operation, ensuring that the powe

r

cable and the power supply unit connector are
disconnected. FIG 3
The control software has the option of setting switching on
time periods, or the safety temperature. See specific
programming manual for further details. It is possible to
set the first two trays with a temperature suitable for
perishable food products.

6– CABINET AND DOOR

Porta vetrata

The cabinet is made of pre-varnished sheet-metal, assembled with rivet

s

and various reinforcements; pre-formed polystyrene foam insulation
panels are placed between the external pre-varnished sheet-metal part
and the internal refrigerated box part.
The advantage of this solution, compared to the injected polyurethane
foam insulation, is mainly form an environmental point of view, as in
the event of future scrapping of the machine, the cabinet can be
disassembled completely without any complications . ( almost
impossible in the case of cabinet injected with foam and welded)
The base is made from sturdy sheeting, welded and varnished to obtain
greater stability. The feet are adjustable for perfect levelling. By
removing the lower grille a regular trans-pallet can be used for routine
moviment of the machine.

The SFERA is provided with two opening systems: main door and side
sliding compartment.
The main door, for loading products, is a glass front type with double
glazing.
The handle for opening is part of the perimeter profile of the frame,
and locking is by means of a single lock located inside the sliding
compartment on the right.

A

sliding compartment is located on the front right side, with the user
interface integrated on its front panel; the CPU board and the payment
system compartment are fitted inside on the central wall.
The following are fitted on the front panel (user interface) : the main
display, the coin slot and the coin return button, the selection keypad
and the lock, that as well as ensuring a three-point lock it keeps the
glass door closed.
The sliding compartment is protected by a safety switch that
disconnects the 230 V AC power, leaving anyway the option of
operating in programming mode by inserting the special key in the
safety switch slot.
The dispensing compartment, with hinged hatch opened from the
upper side, is located on the lower base; such compartment is fitted
with an anti-theft device and anti-vandalism system that will keep it
closed when no selections are made, permitting opening only during a
selection.

Before opening the glass door the sliding door, provided
with a lock, must be opened. To close everything proceed
in the reverse order, i.e. close the glass door, then push
the sliding compartment into position and lock with the
key.

PROBLEM

(and/or indication on the

display)

POSSIBLE CAUSE

SOLUTION

The display indicates the

message:

“Compressor”

If the compressor runs for 24 hours
consecutively without the cabinet reaching
the temperature set via the SW, the machine
is locked and the selection disabled.
The following could be the cause:
Lack of gas in the refrigeration circuit due to
possible leaks.
Failure to the evaporator’s electric fan.
Failure to the condenser’s electric fan or PTC
triggered.
Clogged lower and/or side grille
Failed probe (in this case the message “probe
failure” will be displayed)

Normally two to four hours are required to
reach the operating temperature
(according to the load). A longer time
means that there is a malfunction: check
for any small leaks in the refrigerating gas
circuit; if necessary repair the leak and
charge with the correct dose of gas.
Check that the electric fans work correctly.
Check for the correct cooling airflow inside
the refrigerated box. In the case of failure
to components, replace with original parts.

The display indicates the

message

“Coin mechanism”

If the CPU for more than 30 seconds does
not receive communication impulses from an
Executive serial coin mechanism, or 75
seconds from a BDV serial coin mechanism,
or if it receives an impulse for longer than 2
seconds, the machine locks and the
selections are disabled.

Replace the coin mechanism with one that
is certain to work and check the
communication. Check connections.
Check the CPU board, and if necessary
replace with that is certain to work.
Check that the 24 V DC power supply fuse
is intact.

The display indicates the

message

“RAM data”

One or more areas of the RAM contain wrong
data, which could change the operating
default values.
The machine will continue working, but some
parameters could have been changed, with
consequences to the general functioning ­the RAM needs to be initialised as soon as
possible to recover data from the EPROM.

Initialise the CPU again.
After initialising, all data settings will go
back to the default settings; restore the
customised data using the programmer or
a PC.
If, in spite of initialising, the malfunction
persists, replace the CPU board with an
already tested one that is certain to work.
It the malfunction persists, replace the
cables or check the suitability of
connections.
The machine was designed to comply with
the EMC directive, but if located in an
environment subject to high interference
immunity problems could arise, therefore
in the event of such interference persisting
the vending machine should be moved to
a different location.

The display indicates the

message

“Probe”

The temperature control probe in the
refrigerated box is of the NTC type, with the
internal resistance that lowers as the
temperature rises.
If the probe is interrupted, the machine locks
after 5 minutes from the failure and the
selections are disabled (THE DISPLAY WILL
INDICATE THE TEMPERATURE – 5 ° C)
If there is a short-circuit in the probe, the
machine locks after 60 minutes and the
selections are disabled (THE DISPLAY WILL
INDICATE THE TEMPERATURE +32° C)
NB: AFTER THE SENSOR FAILURE HAS BEEN
DISPLAYED FOR TWO HOURS, A
COMPRESSOR FAILURE WILL ALSO BE
INDICATED.

Check the internal resistance in the NTC
probe using a digital multimeter: A
resistance of 730 ohm corresponds to a
temperature of 30° C.
A resistance of 2612 ohm corresponds to a
temperature of 0° C (melting ice).
Replace the probe with an original one;
before installing the new one check that
the internal resistance corresponds to the
above parameters.
Reset the failures by accessing the special
software function. See programming
manual

7 – TROUBLESHOOTING

NECTA SPA TECHNICAL MANUAL “SFERA “

Manual “ SFERA” 16 / 19

The display indicates the

message

“Motor failure n. XY”

At machine start, an automatic test routine
checks the presence of trays and their
number, therefore a motor failure is not
indicated, as they are not activated. When a
selection is made a microswitch is activated,
which must close at the end of the cycle;
should this function not occur the motor
locks or continues running because of an
actuation card failure.
In this case a time-out is triggered to stop
the motor, placing it out of service.

Check that there are no interferences to
the motor rotation.
Check that the motor is efficiently running.
Check that the microswitch is efficiently
working.
Check that in fact there is not a time-out.
If the motor does not pick up at all, check
the electrical connection ensuring that a
24 V DC reaches the motors.
If all checks are OK replace the card, as
the actuation or the software may be
malfunctioning.

The display indicates the

message

“product finished”

This information can be displayed in the
version fitted with infrared sensors. And it
means that the barrier was not interrupted
during a selection due to two possible
causes: 1) end of product, 2) jammed
product

The software automatically tries to make
the product drop with small movements,
and if this fails the selection is blocked. In
this case the failure must be reset after
correcting the problem.
The software allows a new selection to be
made and the customer does not lose his
credit.

The display indicates a

number of trays not

corresponding to the real

situation

At machine start, an automatic test routine
checks the presence of trays and their
number, therefore if a tray is not indicated it
is because it is not electrically detected.

Check that the cables are correctly
connected.
Check that the cables are efficient.

The machine does not

start and the display is

off

The vending machine is protected against
short-circuits with two line fuses (one on
each phase),
with fuses on the secondary winding and on
CPU board power supply (see wiring
diagram).

Check that the fuses are intact and if
necessary replace. First identify the cause
of the blown fuses.
Check the power supply cable.
The transformer’s functioning.

The refrigerated box does

not cool down and the

operating temperature is

not reached in spite of

being correctly set

The cooling unit sucks in air from the lower
section and expels it downwards through the
front grille. This route must be free.
Ensure that there are no objects in the lower
section of the vending machine.

Check that the pre-filter is not clogged.
The amount of refrigerant is not sufficient
The probe is interrupted or short-circuited, or
moved away from the correct position set at
the factory

(After some time the display indicates the

message “probe failure” or “unit failure”, or

both).

The vending machine can be positioned
against a wall,
but no objects can be positioned under the
vending machine base.
Check for small leaks using a special
instrument and detecting foam.
Restore the charge after eliminating the
leak.
Check that the NTC probe is positioned
and functioning correctly.

The internal lamps do not

light

Switching on and off of the lamps can be
programmed; therefore check that such
option was not included in the programming.
Probable failure to the starter / ballast

Check the functioning of the flourescent
lamp, starter and ballast
Check the functioning of the relay card
(SOR) that controls the 230 V AC power
supply
Check in the special software program that
the time band setting is correct.

The display indicates the

message: “programming”

The CPU and payment system compartment
door closure is monitored by a microswitch
that in the event of actuation with the door
open indicates
“Programming”

In this situation it is not possible to have

correct operation.

If the warning is with the door closed, check

the microswitch.

Check that microswitches are activated
correctly, check that cables are not
damaged or disconnected.
Replace the microswitches and/or the
cables

HACCP DIRECTIVE (EEC 93/43 and 96/3)

Outline and instructions for use

Notes: What is indicated by the EC Directive

Directives EEC 93/43 and 96/3 concern the hygiene of food products and are based on the HACCP (Hazard
Analysis Critical Control Point).

The purpose of this directive is to safeguard the consumer health, suggesting a series of actions to be taken by
the vending company, aimed at checking, identifying and correcting any critical aspects in the foodstuff chain,
from the purchase of products and machines to the dispensing of the product.
The HACCP is a system used to analyse any potential risks in the manufacturing and distribution cycle of food
product and to identify critical points where such risks can occur; the system also highlights the actions to be
undertaken and the decisions to be made with regard to such critical points, as well as the implementation of
checking and monitoring procedures.

Therefore, each vending company must develop a Company Hygiene Self-control Manual according to the
provisions of the directive - and if necessary use the information and recommendations formulated by some
associations in the sector. The manual must contain a programming and checking schedule for the hygiene
condition of each vending machine, and when a new machine is added this must be updated immediately.

Important notes:
For a correct use of the machine, the directives must be fully applied. The operator is responsible for

correct operations on a vending machine

HACCP Directives (EEC 93/43 and 96/3)

Guidelines for correct application

 Ensure hygiene control with a special manual for correct hygiene practices.
 After cleaning, do not touch the surface of any elements that may come into contact with food.
 Wash your hands thoroughly, preferably using disinfectant, before starting any hygiene operations
 Use disposable sterile gloves
 Always use a clean cloth to wipe dry.
 Keep the work area tidy.
 Check that the product packages are intact and not damaged.
 Use products within the recommended time period (see expiry date on the package).
 Always use products from the warehouse according to the principle of “first-in first-out”.
 Consumables must be kept and transported separate from the cleaning and hygiene products.
 Drums and sectors must be cleaned regularly (see operating instructions).
 Do not fill internal zones of the machine with products to be loaded in a second occasion.

 The products that need to be kept at a refrigerated temperature must be transported to the location of the

machine in containers that maintain the products at the ideal temperature or in containers that do not allow
excessive temperature difference.

CLEANING THE MACHINE
Carefully observe the following cleaning instructions! Considering that:

The Snakky normally dispenses products with a long shelf life, but it can be enabled to dispense short shelf
life products; in this case cleaning must be more frequent and stricter.
In the following instructions, only the cleaning and hygiene operations for the FIRST case are described.
