1. OPERATING PRINCIPLE

1.1 General operationThe machine works according to a pump systemdeveloped by Bravilor Bonamat. This system hasthe following advantages:� The components that are responsible for the

correct dosing of the water are housed in a coldwater unit. As a result, the largest cause offaults with machines, the formation of scale onthe dosing valves, is limited to a minimum.

� The float that regulates the water level is alsolocated in the cold−water circuit. This is anotherreason why the formation of scale is limited to aminimum.

2 �Copyright Bravilor Bonamat BV

1.2 Water dosing systemAfter a selection key is pressed, the pump motor isdriven with a controlled time and speed. The pumprotor displaces a certain amount of cold waterfrom the cold water reservoir to the bottom of theboiler. As a result, the hot water in the boiler ispushed upwards towards a water selector. Thisselector uses a rotating movement to select itsposition (beverage−dependent). Depending on theselected beverage, an ingredient is dosed which,together with the dosed water, is or is not mixedand poured into a cup.

1.2.1 Initialisation

The machine is switched on with the main switch.On the LCD (Liquid Crystal Display) the followingappear in succession: � all symbols that the display can show.

� the version number of the software(microprocessor) loaded from the factory.

� the version of the software table (Eeprom), alsoloaded from the factory.

This process takes approx. 3 seconds and endswith the steaming cup in the LCD display to showthat this phase has successfully finished.

1.2.2 Filling

The float tank and the boiler are connected by asiphon hose. Together, they form a communicatingvessel. When the machine is switched on for thefirst time, the float tank (fig.2 ) will be empty andthe float (fig.2 A.) will be low.� The magnetic valve (fig.1 ,1.) is opened and fills

water in the float tank with a speed of 2 litresper minute, depending on the pressure.

� The water in the float tank flows to the boilerthrough the hose under the float tank.

� After the water level has pushed the floatupwards, the water level in the float tank is thesame as that of the boiler. The magnetic valveis switched off.

Please note:Because the float tank is filled faster than thewater ”drops” to the boiler, the filling process willbe made with short intervals.

1.2.3 Heating

After the system is completely filled with water,element (fig.1 ,3.A.) is switched on by means of anelectronic relay (solid−state relay) in the machine.

The temperature sensor (fig.1 ,3.B.), which ismounted on the outside of the boiler, measuresthe actual temperature of the water. This ensuresthat the water in the boiler is heated to the desiredfinal temperature.

During the heating, a thermometer flashes in theLCD display. This indicates that the machine is notyet ready for use.

The temperature sensor is of the type NTC(Negative Temperature Coefficient). The higherthe measured temperature the lower theresistance of the sensor.

Hot water has a lower specific weight than coldwater. As a result, the hot water in the boiler willnot want to flow back to the float tank through thesiphon hose at the bottom. That part of the systemwill therefore remain cold. The latter is veryimportant because precisely the parts of the floattank are sensitive for scale.

The temperature sensor is mounted on the outsideof the boiler. As a result, there is no feed−throughin the wall and therefore there cannot be anylong−term leakage.

This measurement is less direct. This is why thetemperature is regulated proportionally. Theheating switches on for a certain time and off for acertain time.

After the period that the heating has been off, ameasurement is made. The next time, the heatingwill be on for longer or shorter.

The higher the temperature in the boiler, theshorter the moments become that the element ison, and the longer the intermediate time becomes.In this way, an accurate temperature is obtained inthe boiler.

There is a second temperature sensor on theboiler (fig.1 ,3.C.). This sensor monitors the outlettemperature of the dosed water. If this sensormeasures a too low temperature, the machine isblocked. No more water is dosed.


1.2.4 Dosing

Dosing is allowed when:� The float is in the top position.

� The second temperature sensor measures atemperature higher than the blockingtemperature.

� After a selection key is pressed, the pumpmotor (fig.4 ) is driven for a certain time,depending on the programmed amount, with acertain speed (number of revolutions).

Fig. 4 Pump motor + rotor

� The pump rotor rotates in the pump chamber,which is filled with water. This is formed by thebottom of the float tank and the underneath ofthe pump housing (fig.5 ).

Fig. 5 Pump housing

� The pump rotor pumps the water out of thepump chamber, through the siphon hose in thebottom of the boiler.

� As a result, the hot water in the boiler is pushedout of the boiler.

� The float and the magnetic valve ensure thatthe level in the float tank is maintained and thatwater remains in the pump chamber.

The volume of the displaced liquid (yield) is mainlydetermined by the time and speed of the pumpmotor.

The time that the motor is on is regulated from thesoftware and is very accurate.

The number of revolutions of the motor ismeasured with an active revolution counter.

Figure 6 shows that a disc is mounted on the shaftof the pump motor (A = Encoder). This discrotates at the same speed as the pump rotor.

The encoder rotates between a light sensor (B)and interrupts a light beam. The interruption of thelight beam is converted to pulses that can be readby the electronics.

A B

Fig. 6 Encoder

This forms an active revolution regulation thatguarantees that, during the time that the pumpmotor is on, the speed and thus the water yieldremain constant.

Selection of the dosed hot water: This machine is fitted with a hot water selector.This component (fig.7 ) is responsible for thedosed water from the boiler being dosed in aminimum of 3 and a maximum of 6 directions(type−dependent).

Fig. 7 Water selector

Fig. 8 Water selector internal


Fig. 9 Water distribution disc

After the machine is switched on, the waterselector goes to the stand−by position accordingto the following procedure:� The water selector motor is driven.

� This motor uses a plastic worm to drive thewater distribution disc (fig.8 / 9 ).

� The cams on the distribution disc interrupt thelight beam of the light sensor and pass thesepulses to the control (fig.10 ).

� When the light sensor observes the wide camon the distribution disc (fig.10 / 11 ), the initialposition is determined.

Fig. 10 Water distribution disc

Fig. 11 Water distribution disc with wide cam

Operation of the water selector after a selectionkey is pressed:� Depending on the selected beverage, the water

selector determines its position.

� After the position is determined, the pumpmotor is driven.

� The dosed hot water is pumped into the top ofthe water selector (fig.12 A).

� The water runs through the central hole of thedistribution disc (fig.12 B). It comes out throughthe slanted hole at the bottom (fig.12 C).

� After this, the water falls into one of thechambers in the bottom of the water selector(fig.12 D).

� The water runs to the relevant part through thehoses that are connected to the water selector.

� The water selector rotates back to its initialposition.

Please note:The arrow in fig.12 A shows a small hole on thetop of the water selector cover. This is an aerationhole, which prevents siphoning. A hose, whichgoes to the top of the float tank, is connected tothe tulle.

Please note:Depending on the selected beverage, the waterselector can also rotate during the pumping. Thisis done if water has to go to several mixingsystems.

A B C DFig. 12 Water selector components


1.3 Powder dosing systemThe powder dosing system consists of aningredient holder (canister) that is driven by amotor (canister motor).

After the start key is pressed, the canister motorwill rotate after a certain delay. This motor drives aworm, which transports the ingredient to thecanister outlet.

The control of the canister motor makes it possibleto regulate timing and dosing speedindependently. As a result, the ingredient can bepoured into the mixer at the same time that thewater flows out. However, the canister motor willstop slightly earlier than the water, to rinse themixing jug clean.

Depending on the type of ingredient, “beatersprings” are used in the canister. These springsensure that less tunnel formation occurs. This isthe caking of ingredient against the walls.

Fig. 13 Outlet canister


1.4 Mixing systemThe mixing unit (fig.15 ) mixes the hot water andthe ingredient. After a selection key is pressed, thewater will be dosed in the mixing chamber after acertain delay. The product falls into the mixingchamber from above. Depending on the selectedbeverage, the mixer will start to rotate with acertain number of revolutions.

An exhaust opening is mounted on top of themixing chamber (fig.14 ). This cover has anopening at the rear, which is pressed into anexhaust opening through the sheet−metal work.The function of this exhaust system is to ensurethat vapour from the mixing chamber does not getthe chance to reach the ingredient holder outlet.Figure 16 shows an example of an exhaustsystem suited for three mixing systems.

Fig. 14 Exhaust hood

Fig. 15 Mixing unit

Fig. 16 Exhaust system for three mixing systems

1.5 Ventilation systemThe ventilation system (fig.17 ) removes thesteam, that developes during dosing. So thesettling of warm steam and condensation in themixing chamber will be prevented. Therefore themixing chamber will get less dirty.

Fig. 17 Ventilation system


1.6 Operating systemThe operating system consists of a:� Keyboard

� Main board

1.6.1 Keyboard

The keyboard is the printed circuit board with selection keys. Settings that can be changed inthe programming menu are also saved in theEeprom of this printed circuit board. When thekeyboard is replaced, the machine will thereforehave the factory settings.

1.6.2 Main board

The main board is located in the machine and isfitted with electronics to drive the machine. Thepower supply for the low−voltage currentcomponents is regulated from this board, as wellas the temperature regulation. On this board,there are one or more relays and semiconductorsthat can switch the electrical components on oroff.The main board is also fitted with amicroprocessor that regulates the boiler routine.


1.7 Hardware protectionsThe machine is equipped with a number ofhardware protections. These protections ensurethat no dangerous situations can arise, such asoverheating and/or water in the machine.

1.7.1 Overflow protection

This protection is in the float tank and ensuresthat, if the water becomes too high, excess wateris passed through the overflow and hose to thebottom of the machine.

1.7.2 Back−flow protection

The water from the magnetic valve is sprayedagainst the cover of the float tank, via a pipe in thefloat tank. Then, it goes into the float tank itself. Inthis way, water is prevented from flowing back intothe system and getting into the water system if thewater pressure is released from the magneticvalve.

1.7.3 Boiling protection

The boiling protection consists of a relay on themain board (printed circuit relay) and atemperature sensor against the boiler. Thisprotection ensures that the machine can not boil.The separate electronic relay (solid−state relay) inthe machine is connected in series to amechanical printed circuit relay on the main board.This printed circuit relay is switched on when themachine is switched on and contains water, andswitched off when the machine is switched off.The solid−state relay is regularly switched on andoff to keep the water in the boiler at the righttemperature. The printed circuit relay does notswitch much. If the solid−state relay becomesdefective, this can make a direct connection. Thisis why the heating element is permanentlyswitched on. The temperature sensor constantlymeasures the temperature of the water. When thewater temperature is too high, the operatingsystem switches the printed circuit relay off. Thus,the heating element will also be switched off. Thisprevents the water from boiling.

1.7.4 High temperature safetyswitch

The high temperature safety switch is mounted onthe outside of the boiler by means of two Klixons.If, for whatever reason, the operating system doesnot switch the boiler off, the Klixons ensure thatthe voltage on the element is mechanicallyswitched off.

During the boiling dry process, evaporationescapes from the boiler. This vapour enters thewater selector and can possibly exit between thecover and distributor. To prevent a few drops fromentering the machine, a drip tray for the waterselector has been made (fig.18 ).

Fig. 18 Drip tray water selector


1.8 Software protectionDepending on the type of machine, it is providedwith a number of software protections. Thesoftware looks at all inputs and outputs of themachine during the entire process. If situationsarise that are not allowed, the software intervenes.This intervention usually results in the machinebeing switched off and an Error message in theLCD display. For possible solutions to these Errormessages, see the Error list underneath.

Fig. 19 LCD display with error message

ERROR LIST

Error 1 Not applicable

Error 2 Temperature in boiler too high:− If the temperature sensor (NTC)

measures a value that is outside its range(0 Ohm or infinity), the machine isswitched off and ’Error 2’ appears in theLCD display. This also applies if theboiling protection (see hardwareprotection) is activated.

Error 3 Magnetic valve open without selection:− When the start key is pressed, the

magnetic valve is activated. If this valve isactivated without the start key beingpressed, a timer is switched on. If themagnetic valve is activated again withinthis time without the start key beingpressed, this indicates a leakage in thewater system or that the water is boiling.The machine is switched off and ’Error 3’appears in the LCD display.

Error 4 Not applicable

Error 5 Water selector in wrong position:− The water selector returns to its initial

position during start−up and after eachdosing. If the selector cannot find itsposition during the execution of thisroutine, it switches off and ’Error 5’appears in the LCD display.

Error 6 Magnetic valve opened too long:− If, for whatever reason, the process of

filling the float tank takes too long, themachine is switched off and ’Error 6’appears in the LCD display.

Error 7 Wrong Chip card:− In a number of cases, it is possible to place

a chip card in a chip card reader. This ispresent on the keyboard. Any data presentcan be downloaded or uploaded. If thesoftware on this chip card does notcorrespond with the software in themachine, ’Error 7’ appears in the LCDdisplay.

Error 8 Communication error between both prints:− There is constant communication during

machine start−up and during use. This isdone via the flatcable between thekeyboard and the main board. Ifcommunication is impossible, ’Error 8’appears in the LCD display.

Error 9 Pump motor rotates too slow or does notrotate at all:

− The pump motor is rotating during machinestart−up and during use. The light sensordetects no or too little pulses and ’Error 9’will appear in the LCD display.


1.9 ProgrammingThe programming is built up by means of a simpleprogramming carrousel. Have the user instructionsopen next to this text.
