GENERAL DESCRIPTION
8. The Vitro X3 Beverage Machine is a table top unit which may be mounted on a secured
table, bench, cabinet or food and drink counter.
Cabinet Front
9. The cabinet front door has a large glass panel and located within this panel are 10
capacitive touch switches. On the rear of the door is the display for accessing product
information and machine settings with an internal keypad which provides access to the
Operator’s and Engineer’s Program and a USB port
10. The panel can, when unscrewed, be hinged to give access to the ZMCU control board,
button control board, ZMCU adaptor and capacitive touch PCB’s.
Cabinet Rear
11. The rear lower portion on the cabinet has six screws which if removed allow the espresso
boiler, solid state replay, pump and valves to be accessed by sliding the metalwork which
all of this is mounted onto out.
Cabinet Interior
12. A swivel open door provides access to the three plastic product containers, each fitted with
a gear driven worm screw located in the base of each canister to dispense ingredients in
exact amounts. Accessed through the lid of the machine is the forth bean hopper canister.
The ingredients are mixed with hot water in mixing bowls prior to the beverage being
poured from the dispense head.
A plastic agitator is located inside of the milk topping and chocolate canister to ensure free and
consistent flow of product. Additionally a whipper unit, located beneath the mixing bowls,
ensures that the product and water are correctly mixed.
The ingredient canisters must be removed for filling of the products and when all four canisters
are removed and steam hoods of the mixing bowls are removed the extract chamber can be
removed for cleaning.
13. Located on the rear of the machine on the back left hand panel is the machine on/off
switch, which controls the power to the MPU, power supply. Access to all other components
is either by removal of the lid assembly/boiler cover and motor shelf.
14. Further access to the inner components is achieved by removing the left-hand side panel
by unscrewing the location screw and then the panel will drop down clear of its keyhole
slots. Removing this panel gives access to all internal components.
15. The mains electricity supply cable enters the machine via a cable gland on the base panel
of the machine, where it terminates in a terminal block. The supply is then connected via
the terminal block, line filter to the on/off switch on the front of the machine.

WATER SYSTEM
16. The main water supply enters the machine via a double inlet valve, which is mounted in the
cabinet base panel. A length of tube then takes the water supply into the top of the water
boiler via an air break into a channel, which is directed, to the bottom of the heater tank for
the instant products.
The Espresso system water enters through the same double inlet valve mounted in the
base of the cabinet. The water then enters an internal water tank where it sits before being
pumped via an ULKA pump into the espresso boiler.
17. Instant hot water is dispensed from the boiler, via the appropriate solenoid operated valve,
to the mixing bowl. A length of tube directs any overflow from the boiler via overtemp safety
thermostats to the waste tray.
Espresso hot water is dispensed from the boiler, via the appropriate solenoid operated
valve, to the brewer group. A length of tube attached to the purge valve on the top of the
coffee valve directs any overflow into the water tray. The boiler is protected via overtemp
safety thermostats to the waste tray.
18. The cold water mains supply enters the machine at the back of the cabinet and connects
with a double solenoid operated inlet valve, which controls the flow of water to both the
instant and espresso boilers. The water is maintained at a constant level in response to
signals from a water level probe which is connected to the Controller Board for the instant
and a volumetric counter for the Espresso system.
19. The water is heated to the required temperature by a single heating element in the instant
boiler and a single element in the espresso boiler. The Controller Board ensures that the
temperature is maintained to a predetermined level by controlling the supply to the heater in
response to signals from the N.T.C. temperature sensor which forms part of the
level/temperature probe assembly in the Instant boiler and temperature sensor in the
Espresso boiler.
20. Hot water from the boiler is fed directly to the mixing bowls where it mixes with the
dispensed ingredient to produce the selected beverage. Solenoid operated valves
distribute the hot water to the selected mixing bowl, the amount of water being determined
by the program setting.
21. The temperature of the water is monitored by the Controller Board via a sensor inserted into
the tank, thus causing the supply to the heater to be removed when the water in the boiler
reaches its required temperature setting. If the temperature in the boiler increases causing
the water to boil over, the water will flow down the overflow pipe over the overtemp sensors
which will cut off the electrical supply to the heating elements. These sensors are mounted
on the cabinet rear and are re-settable.
Heater and Boosting
22. The instant heating control system employs an intelligent algorithm to obtain maximum
performance as follows:-
Boost operation takes place when the inlet valve opens following a selection being taken. The
heater control algorithm is instructed to turn on the SSR’s for the duration specified in the
variable CUP BOOST referred to Section 2 paragraph 24.
If the temperature is 50 more than the DESIRED TEMPERATURE, set in the CHANGE
SETTING MENU (see Section 2 paragraph 24) all boosting operations are disabled.
If the actual temperature is between 0 –35 less than the DESIRED TEMPERATURE one SSR

is OFF and the other one toggles ON & OFF unless a boost operation is in progress then both
SSR are ON.
If the actual temperature is between 35 - & 50 less than the desired temperature one SSR is
ON and the other is OFF. Boost operations are as above.
If the actual temperature is more than 50 below the desired temperature both SSR’s are ON.
The Espresso system also has a boost control which operation takes place when the heater
control is instructed to turn on the SSR’s for the duration specified in the variable GRP
OVRDRVE TIME referred to Section 2 paragraph 24.
The GRP OVEDRVE TIME is located in the CHANGE SETTINGS menu. If a coffee based
vend has not produced from the machine inside the specified time of the GRP OVERDRVE
TIME the next coffee based vend produced from the machine will heat the Espresso boiler to
the specified GRP OVRDRVE TEMP from the CHANGE SETTINGS MENU to ensure a cooler
vend is not to be produced

Tank Filling & Overflow Protection
23. The control system will only open the inlet valve for a maximum of 40 seconds. If the tank
is not full at the end of this time the machine will enter a fault condition. The internal display
will read “TANK FILL FAULT CALL OPERATOR” for the Instant system or “GROUP
WATER SYSTEM FAUT” for the Espresso. This fault can be cleared by switching the
machine off and on and attempting a refill.
Note: An empty tank may take several cycles to fill completely depending on water pressure.
24. The second protective mechanism is designed to act as a fail-safe in the event that a slow
leak occurs which does not result in the liquid entering the drip tray. The machine will
cease all attempts to fill the tank after 20 tank top ups have been made, if no selections
have been taken in the meantime.

ELECTRICAL AND ELECTRONIC SYSTEM
Functional Description
25. The MPU Controller Board employs Microprocessor technology to monitor and control the
operation of the beverage machine. The board contains the main System Program, the
Operator’s Program and the Engineer’s Program, each stored in programmable read only
memory.
26. Variables, such as the amount of ingredients dispensed, are stored in non-volatile random
access memory (NVRAM) and are called up by addressing either the Operator’s Program
or the Engineer’s Program as appropriate.
27. The main System Program tasks the microprocessor with continually checking the status of
the input devices (keypad, probe, etc.) and responding to data received by signalling the
output devices (LCD display, motors, whippers etc.) to take the appropriate action. The
System Program also requests the microprocessor to interrogate the variable settings in
NVRAM and to modify its actions accordingly.
28. Output transistors and F.E.T. devices on the MPU Controller Board convert signals from the
Controller’s microprocessor circuit to the current drive necessary to operate output devices,
i.e. motors, whippers and inlet valve.

Circuit Description
29. If the beverage machine is supplied by a 230V~ single-phase supply from a 10A or 16A
outlet (or from a 13A domestic outlet), only one heater can be connected in circuit a 15A
fuse protected heater circuit, a solid state relay (SSR) contact and high temperature cut-out
is placed in the circuit of heater, there is one circuit to protect the Instant boiler and the
same to protect the Espresso boiler.
30. The SSR switches the supply to the heaters as directed by the MPU Controller in response
to data received from the temperature sensor part of the temperature/level probe for the
Instant boiler and purely the temperature probe for the Espresso boiler, thus maintaining
the water in the boiler at the correct temperature. However, if the water in the boiler starts
to boil, the high temperature cut-outs remove the supply to the heaters. A reset button for
the Instant cut-out is accessible at the top of the machine and the Espresso boiler cut-out is
accessed by removing the left hand side panel and depressing the cut-out directly on top of
the boiler.
31. A 230V~ ac main supply is taken from terminal block to the Power Supply PCB via the
on/off switch. The Power Supply PCB provides DC supplies of 24V, 12V and 5V. The 24V-
dc output supplies the ingredient motors, whipper motors, extract fan, SSR and solenoid
operated valves. The 12V-dc output supplies the MPU Controller Board and operational
coin acceptor (if fitted).
32. The MPU Controller Board continually checks the status of input devices connected to
plugs J1 and J3, and responds to any change of state by signalling the operation of the
relevant output devices via on-board current drive transistors. Thus, for example, the water
level probe controls the operation of the inlet valve and the temperature sensor controls the
operation of the SSR.
33. The dispensing of a beverage begins with the keypad selection, which is scanned by the
MPU Controller Board via a ribbon connector. Control Signals corresponding to the
required actions are then generated by the MPU Controller to operate the relevant output
devices in the correct sequence and for the specified duration. Operator data information is
sent in parallel form to the (LCD) Display.

SELECT DRINK TO MODIFY -INGREDIENT/WATER/WHIPPER ADJUSTMENTS PROGRAM
18. The Vitro Espresso Duo program provides total flexibility in setting the function of the
selection buttons. Each button has the possibility to add to its recipe any of the ingredients
in the machine. Thus, for example, the button programmed to dispense chocolate will have
in its control variables list, parameters to control the coffee, topping and tea motors, mixers
and valves. It would in theory be possible to program a button to have a little of each
product available. The program is arranged in sections showing the start time and running
duration for the ingredient motors, dispense valves and mixer motors. There is a start time
and running duration for each actuator. The times are in tenths of a second. In addition to
this other selection, specific parameters are included in the list of settings that can be
changed.
The SELECT DRINK TO MODIFY menu now features adaptive menus to hide settings from
view until they are required. For example, a drink which utilises milk ingredient will find
additional milk ingredient times are available to facilitate greater drink customization. The
adaptive menus are,
CHOCOLATE ING 2 & CHOCOLATE ING 3 –If a chocolate ingredient duration is set then
these additional settings will also appear.
MILK ING 2 & MILK ING 3 - If a milk ingredient duration is set then these additional settings
will also appear.
TBRW WTR1, TBRW WTR 2 - If the tea ingredient is set and the machine has a tea brewer
these variables will become visible for customization of the brewer component of the drink.
19. The settings for a selection are accessed using the SELECT DRINK TO MODIFY menu as
follows:
With the SELECT DRINK TO MODIFY menu displayed, press the selection button on the front
panel you wish to change.
Access will then be granted to the list of configuration parameters for that selection.
The list is navigated using the , arrows and ENTER or ESC to select items to change.
20. The first entry in the SELECT DRINK TO MODIFY menu allows the drink name to be
changed. In general, on Coffetek equipment the drink name has no effect on the behavior
of the selection button. Choosing a drinks name on some competitor’s equipment actually
configures the selection, so this point should be noted. The primary purpose for the drink
name change facility is to allow the correct name to be displayed when a selection is taken
or when using the auditing features. With the exceptions listed in the table on page 17 the
drink name assigned to a selection button has no effect on the selection, other than to
