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 right-
hand 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. 
As 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).

4 - POWER SUPPLY AND WIRING

 

Like all other NECTA products, the “SFERA” vending 
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.

 

All 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.

 

The power supply unit transforms the grid electricity to 24 V 
AC and the CPU board acts as rectifier and controller of 
actuations to the power users. 
All actuations are under extra-low safety voltage, while the 
lamps and the cooling unit are controlled by means of 
special relay cards at the grid voltage. 
The power supply unit is housed in a removable galvanised 
steel metal box for greater accessibility. 
When opening the door a safety switch is deactivated, 
disconnecting the power from all accessible parts. 
The unit is protected by electrical interference suppressor 
systems in conformity with the European directives. 
The power supply unit houses a safety transformer for the 
extra-low voltage, the grid fuses, the transformer secondary 
winding fuses, the fluorescent lamps ballasts, the relay card 
for controlling the cooling unit, the noise interference 
suppressors and the safety switch.

5- COOLING UNIT  

The internal temperature controlled by means of an 

NTC

type electronic, controlling a traditional type cooling unit,
but with design features that will bring it to the top of
what is currently available on the market. 
Yje NTC probe has an internal resistance that varies
according to the ambient temperature change. 
At the temperature of 0° C it is 2612 Ohm 
At the temperature of 3° C it is 2267 Ohm 
At the temperature of 30°C it is 733 Ohm 
This way the software controls the unit switching on and
off with extreme accuracy. 
The 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 or
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.  The 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 evaporator
during the extraction operation, ensuring that the power
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 rivets
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

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.

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 

(

H

azard 

A

nalysis 

C

ritical 

C

ontrol 

P

oint). 

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. 

 
Clean the machine, preferably at the end of the day or in the morning before the machine is used, and 

before loading the products to be sold. 

 

 

Fill in the checklist log for cleaning operations. 

 

When the display indicates an error message immediately check the trouble-shooting sheet. 

 

Use only recommended cleaning products approved for foodstuff, preferably liquid; do not use powder and 
abrasive products that could scratch plastic surfaces.
