selection. All beverages are dispensed in cup measurements. A liquid crystal display provides status indications and operational information. All operations are microprocessor controlled. 2. A cup is placed under the dispense head and the selection is made via a capacitive key selection. The drink is then dispensed in the required quantity. The machine does not accept money, but a feature such as this can be added. 3. The status of the machine may be monitored, and the configuration altered, by accessing a program using the keypad and display. The program offers a menu of options; each consisting of a number of sub-options which can be altered. 4. The Vitro S3 Beverage Machine has a feature, which heats the water in the boiler very quickly, with one heater connected, from a 230V~, 16A single-phase supply. FIG 1.1 VITRO S3 BEVERAGE MACHINE Model shown is S3 FBT

Supply voltage : 230V~, 50Hz, single phase, fused supply Current rating : 10A/16A (b) The fused electrical supply should terminate at an appropriate isolator located within 1m of the beverage machine. Water Supply 6. (a) 15mm dia. Water mains supply, terminating at a convenient stop tap located within 1m of the beverage machine. (b) Water pressure : 0.1 MPa minimum, 0.8 MPa maximum (c) A 15mm double backcheck valve, with inspection port, should be fitted prior to the flexible hose. The mains Water Supply should be fitted with a suitable water blocker.

secured table, bench, cabinet or food and drink counter. Cabinet Front 8. 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 9. 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 Interior 10. A swivel open door provides access to the plastic product containers, each fitted with a gear driven worm screw located in the base of each canister to dispense ingredients in exact amounts. 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 three canisters are removed and steam hoods of the mixing bowls are removed the extract chamber can be removed for cleaning. 11. Located on the upper 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. 12. 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. 13. 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.

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. 15. 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. 16. The cold water mains supply enters the machine at the base of the cabinet and connects with inlet valve, which controls the flow of water to the boiler. The water is maintained at a constant level in response to signals from a water level probe which is connected to the Controller Board. 17. The water is heated to the required temperature by a single element. 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. 18. 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. 19. 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 over the overtemp sensors which will cut off the electrical supply to the heating elements. This sensor is mounted on top of the heater tank and are re-settable. Heater and Boosting 20. The 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 for the duration specified in the variable CUP BOOST If the temperature is 3° more than the DESIRED TEMPERATURE, set in the CHANGE SETTING MENU all boosting operations are disabled. If the actual temperature is between 0 – 1.5° less than the DESIRED TEMPERATURE the SSR toggles ON & OFF unless a boost operation is in progress then the SSR are ON. If the actual temperature is between 2° - & 3° less than the desired temperature the SSR is ON. Boost operations are as above. If the actual temperature is more than 3° below the desired temperature the SSR’s are ON.

21. 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”. This fault can be cleared by switching the machine off and on. Note: An empty tank may take several cycles to fill completely. 22. 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.

Functional Description 23. 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. 24. 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. 25. 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. 26. 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. FIG 1.3 ELECTRICAL & ELECTRONIC SYSTEM – FUNCTIONAL DIAGRAM 1. HEATER SSR'S VALVES MOTORS/FAN CONTROLLER BOARD WATER LEVEL KEYPAD TEMP SENSOR DISPLAY PUSHBUTTONS Capacitive Touch Screen Selection

outlet (or from a 13A domestic outlet), only 15A fuse protects the heater circuit, a solid state relay (SSR) contact and high temperature cut-out is placed in the circuit of heater 28. 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, 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-out remove the supply to the heater. Reset buttons for cut-out is accessible at the top of the machine. 29. 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). 30. 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. 31. The dispensing of a beverage begins with the keypad selection, which is scanned by the MPU Controller Board via a ribbon connector. Which passes through the button control board to the MPU. 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.

program and the Engineer’s Program. The Operator’s Program is available to both the Operator and the Service engineer, but the Engineer’s Program is only available to the SERVICE ENGINEER. 2. Both the programs are stored in programmable read only memory on the Controller Board. The values and settings (Variables), which the program allows the programmer to alter, are stored in NVRAM (non-volatile random access memory). 3. Settings are maintained, without the need for back-up battery, when the power supply is removed.

KEYPAD FUNCTIONS 4. The Operator’s Program is available to the operator and Service Engineer. The Program provides options for counting the number of drinks dispensed for each beverage, monitoring the weight of ingredients used, showing the total vends dispensed and resetting the drink dispensed counters if applicable. Additionally, the operator can set the machine to Out of Service if required. 5. Keypad functions when used in the Operator’s programming mode, are as follows:-  Key (ENTER) used to access a function.  Key (PROG) used to access the operators program, then used to change menu functions.  ARROWS UP (), DOWN (), LEFT (), RIGHT () are used for adjustments when in program mode.   key is used for selecting option when in output test mode. FLUSH PROG ESC ENTER

6. Accessing the Operator program is by pressing the PROG key on the internal keyboard. The display will show: PRESS DRINK TO DISPLAY COUNTER DISPLAY COUNTER 7. The DISPLAY COUNTER option is accessed on entering the Operator’s Program. The resettable vend counts may be viewed by pressing each drink key (as shown on the keypad) in turn. 8. To access other options, press PROG on the internal keypad. The other options are as follows:  Total Vends  Reset Counters  Disable Vends  Reset Grout Counter  View Ingredient Counters  Machine Serial No. TOTAL VENDS 9. Access the Total Vends Count option using PROG key, the display will show total vend count. RESET COUNTERS 10. Access Reset Counters by using PROG key, to clear drink counters press ENTER. The display will show: ARE YOU SURE ENTER (Y) ESC (N) DISABLE VENDS 11. Access the DISABLE VENDS option by pressing the PROG key and then press ENTER when DISABLE VENDS is displayed. This will then disable all of the vends selections until they are re enabled. VIEW INGREDIENT COUNTERS 12. Access the View Ingredient Counters option by using PROG key. Press ENTER to display the first counter, then press the  UP arrow to scroll through the others.

13. Access the MACHINE SERIAL NUMBER by pressing the PROG key until the machines serial number is displayed on the LCD display.

Repeated pressing of PROG key causes the program to scroll through the options in the above sequence. Therefore a specific option is accessed by pressing PROG key until that option is displayed. To access any program press ENTER.

17. The Vitro S3 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 decaf/espresso 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. CBRW WTR1, CBRW WTR2, CBRW LOCK DELAY, CBRW AIR1, CBRW AIR2, CBRW SHOT – If the coffee ingredient is set and the machine has a coffee brewer these variables will become visible for customization of the brewer component of the drink. 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. 18. 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. 19. 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 21 the drink name assigned to a selection button has no effect on the selection, other than to control the characters displayed on the LCD screen when that selection is taken.

DRINK 03 NAME IS (IF NAME IS CORRECT MOVE TO STEP 4) where is the displayed name for that drink, e.g. Coffee.  To change the name Press ENTER. The display will show: ,  ENTER OR ESC  Use the   keys to scroll through the available drink names. Press ENTER to confirm the new name or ESC to return to the old one. A limited number of names do affect the function of the buttons to which they are assigned. These special names and their effects are listed in the following table: GO LARGE / ALT KEY This button becomes a ‘GOING LARGE / ALT KEY’ key. If pressed the machine will emit two beeps to show it is in ‘large/alt’ mode and the next drink to be selected will use the alternative set of presets associate with the other selection buttons. Typically these alternate selections will have been set to give a larger version of the standard drink in order to realise a GO LARGE function. Equally though the alternative selection could be configured to give Decaf selections.  If drink name is correct, use ,  to step through the program. The display will show: USES NOZZLE000  Press ,  to show Ingredient Settings. Display will show: Where is the name of the ingredient assigned to bin A (see EDIT BIN NAMES). Typically ingredient A is Milk 000 (Start) Time after button pressed that ingredient A motor starts in tenth of a second. 000 (Duration) Time for which ingredient A motor runs in tenths of a second.

FLUSH BOWL A 060 (Start) At the end of a dispense cycle it is possible to program a small amount of water through the large mixing system to clean it and prevent drips. These parameters control the timing of this FLUSH BOWL A 010 (Duration)

Note. Only occurs on last cycle of multi-cycle drinks. VEND DELAY 060 (Start) Under some circumstances it is desirable to have a pause between cycles of a multi-cycle selection. Theses variables provide the means to achieve this. VEND DELAY 010 (Duration) NUMBER OF CYCLES 001 Number of times settings repeat. For example set to 2 for a two cup pot. SCALE FACTOR 100 Scale factor applied to basic drinks settings. To accommodate different drink sizes. Operates on all settings together.  To adjust the drink, first select the parameter you wish to change. For example to adjust the Coffee strength scroll through to the parameter controlling the run time for the coffee ingredient motor. The display will show for example: COFFEE 010 (DUR)  Press ENTER - display will show: COFFEE VALUE = 012 (FLASHING DIGIT)  Press  to increase or  to decrease.  Press ENTER to accept the new value.  Press  to step through program to adjust other value or press ESC to return to SELECT DRINK TO MODIFY, then press ESC again to return to normal operating mode. SELECT DRINK TO TEST 20. The SELECT DRINK TO TEST option allows any selected drink to be dispensed, while still in the Engineer's Program, in order to be tested. This facility is useful for testing a drink that has been modified. Press DRINK A, for example, to test a change made to the selection in the SELECT DRINK TO MODIFY option. MOVE OR COPY DRINK 21. The MOVE OR COPY DRINK option facilitates the rapid movement or cloning of a drink to another physical button on the keyboard. This is to aid the customization of menus to suit requirements in the field on an individual machine basis. Three options are available.

 COPY DRINK – the selected drink is copied to the destination button but remains at the original button also.  MOVE (ERASE ORG) – the selected drink is moved to the destination button but the original button is erased to facilitate adding a simple drink such as hotwater manually. Most of the more complex drinks would probably be copied from other drinks for instance a Café Latte might use an existing Cappuccino drink as a template. 22. To move or copy a drink  Press the ENTER key on the MOVE OR COPY DRINK menu.  The Display will show, SELECT DRINK TO MOVE OR COPY  Press the key of the drink that you wish to move or copy. Once you have done so the keyboard led of that drink will remain illuminated.  The display will now show, PLEASE SELECT DESTINATION  Press the key that you want the selected drink to be moved or copied to. The destination key will now flash and the display shows… SELECT PROCEDURE SWAP DRINKS  The bottom line of the display shows the currently selected procedure. Using the  (UP) and  (DOWN) keys you can choose from the options explained above namely SWAP DRINKS, COPY DRINK and MOVE (ERASE ORG). Once you are happy with the selection press ENTER to confirm or ESCAPE to cancel. 23. NOTE: If there is an ALT or GO_LARGE key assigned to a button an extra step will be required. As soon as you press ENTER on the MOVE OR COPY DRINK menu the display will show… DESTINATION OPT’ REGULAR->REGULAR  Press  (UP),  (DOWN), ENTER (SELECT) and ESCAPE keys to select the appropriate option. There are four possible options to choose from.  REGULAR->REGULAR – Copies a regular sized drink to another regular drink position.  REGULAR->LARGE – Copies a regular drink to a large drink position. This is often used so a regular drink can act like a template for a larger one.  LARGE->LARGE – Copies a large sized drink to another large sized drink position.  LARGE->REGULAR – Copies a large drink to a regular drink’s position.  Once an option is selected the process becomes exactly the same as when an ALT or GO LARGE key has not been asserted.

 (DOWN), keys are used to move through the list of output devices. When the desired device is displayed use the STAR key to switch the device ON/OFF For example, to operate the coffee mixer motor select COFFEE WHIPPER by pressing  until it appears in the display window, then press STAR to switch the motor ON. CHANGE PRICE OF, OR INHIBIT DRINKS 25. The CHANGE PRICE OF, OR INHIBIT DRINK option allows individual drinks to be priced or inhibited. Changing the price/inhibiting on a paid machine;  Press the drink you wish to set  Use the arrow keys to set the price and press ENTER  If you set the price as 0004 it will inhibit the drink Inhibiting a drink of a free vend machine;  Press the drink you wish to inhibit  Use the arrow keys to change this to Inhibited and press ENTER SET INGREDIENT THROW RATE 26.

To run the bootloader it is necessary to fit the jumper labelled ENG_LK and restart the machine. Once the machine starts up the display will show: BOOTING… (001) 49. The lower line of the display is the Bootloader version number and is not to be confused with the actual firmware version number that can be loaded onto the control board to run the machine. 50. All firmware must be stored in “.\COFFETEK\ZMCU\FIRMWARE” on the USB flash drive. On an operational machine any USB activity which saves data to the flash drive will create this directory automatically. It is recommended to keep this directory small to avoid erroneous firmware being loaded onto the ZMCU. 51. The machine will then search for attached USB devices. If a device is not found the display will show, PLEASE INSERT USB DEVICE 52. If a USB flash drive is attached the screen will briefly say DEVICE PRESENT 53. The bootloader will then scan the USB flash drive to see if any firmware updates are available in the “.\COFFETEK\ZMCU\FIRMWARE” directory. If this directory is not available the display will say NO FIRMWARE DIRECTORY FOUND! 54. If the directory exists but there are no valid files to upload the display will show, NO FIRMWARE FILES FOUND! 55. If a USB flash drive is inserted that does contain valid files the display will change to, SELECT FILE NG648_GB.000

NOTE: It is imperative that the correct version of software for the machine is selected otherwise correct machine operation cannot be assured. Pressing the  (UP) or  (DOWN) key will select any alternative software versions that are also available. Once you have the necessary software version selected press ENTER to confirm you wish to upload or press ESCAPE to cancel. 57. There are three stages which occur when ENTER is pressed. The first is verification that the file has valid contents. If it doesn’t have valid contents the operation is aborted but if it does then the memory storing the old software is erased. Finally the board is programmed with the new software. Once completed successfully the display will show, FIRMWARE UPDATED REMOVE ENG’ LINK 58. IF ESCAPE is pressed or there is a problem with the programming the display will show, REMOVE ENG’ LINK 59. Once the Engineer’s link is removed there will be three short beeps before the machine then restarts with the newly programmed software. 60. After programming it is always necessary to SET FACTORY DEFAULTS so that the machine is running with valid data. On start-up the ZMCU’s memory is scanned for corruption or misalignment and if detected it will prompt the user to set the factory defaults. CORRUPT FRAM SET DEFAULTS?  Press ESCAPE to ignore or press ENTER to confirm where it will then advance you to within the SET FACTORY DEFAULTS menu where you can select the defaults you require.  NOTE: The corrupt FRAM warning only occurs when the structure of the memory is not correctly in place and therefore is most often utilised for uninitialized boards. It is not guaranteed to trigger on each programming of the board so it’s important to remember to set the defaults regardless to ensure the machine works as expected. Quit Engineer Program 61.
