5.1 Hot water system

The water system is positioned at the back side of the machine and accessible from the back. If water and power are connected and the door is closed the water system start filling the boilers automatically.

The water system consists out of the following main components:

1. Inlet valve

2. Pressure reducer

3. Flow meter

4. Vibration pump(s)

5. Boilers

6. Valves (outlet valves and pressure valves)

5.3 Inlet valve

The inlet valve is controlled by the level sensor in the boiler and is switched on during a dispense of hot water to the brewer or mixer. The inlet valve is a 24V DC valve. The inlet valve contains a backflow protection. This backflow protection is preventing that water is flowing back into the water supply. Electrical connections/wire colors:

5.4 Pressure reducer

The pressure reducer reduces the water pressure to a stable pressure independent from the inlet pressure from the mains water supply. The required inlet pressure from the water supply is between 1,0 and 6 bar. The pressure reducer is adjusted to an outlet pressure of about 0,8 - 0,9 bar during an espresso cycle.

The input and output tube to the reducer must be connected in the right direction, the reducer works incorrectly in the reversed mode. There is an arrow on the side of the reducer indicating the correct water flow direction.

The reducer contains a backflow protection. This backflow protection prevents the possibility that water from the machine is flowing back into the main water supply.

Procedure to adjust the pressure reducer:

1. Remove the lower back plate from the machine.

2. Remove the tube clamp and stop. (see picture)

3. Connect the manometer to the tube.

4. Pull out the knob to unlock the reducer.

5. Select an (double) espresso. Adjust the reducer by turning the knob during the pump cycle of the espresso selection. The manometer must show 0,8 - 0,9 bar during an espresso cycle.

6. Lock the reducer by pushing the knob down towards it’s own housing.

7. Disconnect the manometer and replace the tube clamp and stop in the tube.

8. Replace the back plate on the machine.

5.5 Water flow meter/water counter

The water flow meter measures the quantity of the water flowing through the hot water pressure system.

Three functions are based on the water flow meter:

1. The water dosages for the consumptions are based on quantity of the pulses generated by the flow meter.

2. During the start up procedure it is detected if water is flowing into the system. If not, the machine will stop working and show the error messages “start-up problem” and “no water connected”

3. The amount of heating of the boiler is, besides the measurement with the temperature probe, also based on the quantity of incoming water.

The water flow meter is built in between the pressure reducer and the pumps. It is a small turbine which produces electrical pulses. Each 360º rotation produces 2 pulses in the sensor (Hall element). The pulses are detected by the control system.

The tube to the water flow meter must be connected in the right position; the flow meter cannot detect water in the reverse mode. There is a small arrow on the water flow meter which shows the right direction.

The water flow meter is a 1.8 mm type. Each pulse is about 0.8 ml of water.

5.6 Pump

The pumps are generating the pressure and flow of the water. The pumps increase the pressure to the required brewing pressure (1.5 till 10 bar).

The pump is a vibration pump. The plunger vibrates up and down, therewith a pressure can be build-up.

The pump is a 24VAC pump, the electrical signal to the pump is a 24DC block pulse.

The pressure can be adjusted by the electrical signal (pulse-width) to the pump. A longer pulse gives a higher pressure because the plunger is lifted higher. The maximum pulse width is 20. This figure can be set in the service program, individual for every consumption. Because of the high frequency of the pulses this electronic signal cannot be measured with an ordinary volt meter. The pulses for the two pumps runs out of phase so a stable high pressure is offered to brew an espresso.

Machines with one or two pumps:

- The Fresh brew version without a bean hopper (Zia 6000) has just 1 pump and is brewing coffee on a low 1-4 bar pressure.

- The B2C espresso machine has 2 pumps, parallel connected and can brew espresso on 8-10 Bar or coffee on a low pressure 1-4 bar. The variation in pressure generates an excellent coffee or espresso flavor.

Temp. safety

Temperature safety / clixon: The temperature safety switch is positioned on the side of the boiler. In the housing is a bi-metal disk which switch if the device gets too hot. This safety protects the heater against overheating if the control system does not switch off the heater. The temperature safety (normally closed contact) switches off at a temperature of 110ºC +/- 5ºC. The safety switches the current to the heater directly off if the boiler is overheating. The clixon is resettable after cooling down by pressing the pin by hand.

Temperature/Level sensor: The sensor in the boiler is a combined level and temperature probe. The sensor is isolated from the boiler housing with a plastic isolation clamped with two nuts around the stainless steel sensor housing. If replacement is needed the sensor needs to be replaced complete, including nuts.

Temperature:

The temperature is detected by a thermistor mounted in the stainless steel housing. The control system is controlling the temperature in the boiler based on the resistance of the thermistor.

Resistance of the thermistor:

Resistance

Temperature

6.5 k

The temperature is adjustable in the settings of the control system. The optimal temperature setting is 90ºC in boiler 1 and 92 ºC in boiler 2. If no consumptions are made, the temperature in boiler 2 will automatically raise in about 25 minutes to 98º. Herewith the first consumption with a cold brewer is brewed with incoming water on a higher temperature, compensating the colder brewer.

The control system contains some safeties and warnings based on the detected value of the temperature sensor. A too high temperature, too low temperature, shortcut or disconnected sensor is detected by the control system.

- Disconnected temp. sensor is generated if the resistance is above 350 k.

- Shortcut temp. sensor is generated if the resistance is below 1 k

Reset

Level:

The level in the boiler is detected by the stainless steel housing of the sensor. The boiler is connected to ground. On the housing is a positive signal from the control system. If the sensor is in the water, current is able to pass through the water. The control system is detecting the water level because of this current.

5.8 Position of valves in the hot water system

The manifold with valves is connected straight on the boiler with a bolt. This connection is needed to keep the manifold with valves warm if the machine is not used for a while.

2-way outlet valve

The two way hot water outlet valve is equipped with a special disc

between valve and hose nozzle.

This disc has a very small hole (0.7mm) in the middle. All the water

must flow through this very small hole, causing the air in the water to dissolve.

If this disc is not fitted, tea made with hot water will have a foam layer

and will not look appealing.

5.9 2-way valve / outlet valve

The two way valve is the outlet from the hot water system to a component. The moveable plunger has an integral seat which, when the solenoid coil is energized, moves off the valve (direct operated) orifice opening the valve. When the coil is de-energized, a return spring repositions the plunger in the original closing position on the valve, thus cutting off the flow of the fluid. The valve is controlled by 24VDC from the IO-board.

5.11 Pressure valve 2 bar

The 2 bar pressure valve is a mechanical pressure valve. This valve automatic opens if 2 bar pressure is reached. This pressure valve can be switched off electronically by the 2-way expansion valve, in front of this 2 bar valve. The 2-way expansion valve is switched off during a vend cycle. If the system is in ‘standby’, the expansion valve is switched on (open) if the heaters are switched on, so the maximum pressure in the system during standby is 2 bar.

5.12 Safety pressure valve 12 bar

The 12 bar pressure valve is a mechanical pressure valve, in open line with the water system after the pumps. The valve automatically opens if 12 bar pressure is reached. Therefore the maximum pressure in the system can never be above 12 bar if this valve is functioning correctly.

Do not adjust the pressure valves in case of malfunction. They are specially set to 2 or 12 bar, and cannot be set correctly without special tools and knowledge. In case of malfunction replace for a new one.

Replace the tube.

Check the function of the brewer by making a test drink. Place a cup under the outlet.

5.16 Brewer cycle

Home position / Start position

After dosing the coffee the brewer start running. The motor runs clockwise till closed position.

Closed position

The dosed coffee is pressed together between the upper and lower piston. After pressing the coffee together the water is dosed through the piston, into the coffee cake and flows through the filter screen out into the top and outlet of the brewer. The pressure from the piston on the coffee cake is regulated by the adjustable current of the motor.

Open position

If enough water is dosed the brewer runs counter clockwise to the open position.

Waste wipe

The brewer runs through, herewith the lower piston moves to the top position. Now the brewer starts running clockwise and the coffee cake is swiped from the piston into the waste bucket.

Back to home

After swiping the coffee cake away, the brewer runs in the clock wise direction to the home position.

Start/home position

The brewer is ready for a new cycle.

5.17 Brewer motor and micro switch

The upper piston contains the filter, restrictions and pressure switch. This part switches mechanical to the coffee or espresso outlet.

Upper piston.

5.19 Controlling coffee/espresso pressure switch

With the unique patented system the CoEx®-brewer can make Coffee and espresso consumptions in one brewing system. The pressure for coffee and espresso is different, coffee is made with 3 - 4 bar pressure, espresso with 9 bar pressure.

The volume of a consumption is easily changeable in the software settings in the machine.

The duration time that the water is in contact with the coffee powder is a very important factor in the performance of the brewer and is about the same for coffee and espresso. The optimal water-coffee contact time is 15 - 25 seconds

To achieve this value a restriction in the system must be used. By the combination of a higher pressure, lower volume and an equal coffee contact time the flow for espresso must be much smaller than the flow for coffee. In the following figures the solution for making these two beverages in one system is shown.

Coffee cycle:

When coffee is chosen, the start flow is relative low and will not activate the pressure switch. (Spring is strong enough to keep pressure switch in coffee position) The coffee passes the primary restriction and can then flow through the large coffee channel.

Espresso cycle: When espresso is chosen, at first the flow is high and will activate the pressure switch. (Spring is not strong enough to keep pressure switch in Coffee position) The coffee channel is closed and the espresso is forced through the secondary restriction, reducing the flow and increasing the pressure to 9 bar.

This different pressure between coffee and espresso is only used in the B2C espresso machines. (Zia 8000) The CoEx® machines used as paperless fresh brew has no spring to switch between coffee or espresso pressure. (Zia 6000)

5.20 Seals

The brewer contains two pistons, the upper piston and lower piston. There are three sealing responsible for the sealing of the pressure room: Two in the lower piston and one in the upper piston. Hot water enters the cylinder (through the lower piston) between the two sealing rings in the piston.

The mix of water and coffee powder will be filtered by the mesh in the upper piston and then leave the cylinder.

The sealing in the upper piston and the lower sealing in the piston have to resist the pressure of the hot water during the brewing process (10 bars). As distinct from the most competitors this brewer is not equipped with o-ring sealing, rings which seems an important malfunction factor. In the following figure the impact of a coffee grain between the o-ring and the cylinder is shown. The grain will stuck which will result in twisting of the ring and grooves in the cylinder.

The shape of the selected u-cup ring avoids the grains scratching the cylinder. The sealing consists of a Teflon u-shaped ring filled with silicon. Disadvantages of this ring are the higher cost price and the fact that the piston must be divided into a lower piston and a piston head to fix it. The upper sealing in the

piston doesn’t have to resist

the high pressure but is only a scraper.

Two different U-cup rings are used in the brewer: The U-Cup ring in the upper piston has a blue color. The U-cup ring in the lower piston has a red color.

5.21 Replace seals in lower piston

1. Needed tool: Screw driver

2. Unscrew the bolt in top of the brewer and loosen the two other bolts 2 turns.

5.22 Mixer

The mixer consists of a mixer motor, to which a mixer blade and a mixer house are connected. The mixer is controlled by the control board and ensures a correct mixing of the ingredients and the water. Furthermore, the mixer whips air in de consumptions and forms a crème layer. This will grade up the taste and the appearance of the consumption.

Motor specification: 24VDC, 14.000 RPM. In case of a blockage, a safety is actuated on the IO board and the message “mixer blocked” is shown in the screen.

A restricted inlet diameter of the mixer house is used to create a nice flow in the mixer bowl. The used black mixer house is a special made house with inlet diameter for the pressure water system as used in the Zia 6000 an 8000 series.

Disassembling the mixing system:

1. Remove outlet pipes from the ingredient canisters.

2. Turn the bayonet catch counter clockwise (approx. 10º).

3. Remove the mixer house by pulling it towards you.

5. Pull the mixer blade towards you.

5.23 Grinder

The grinder can been build in the door or on the base plate next to the other ingredient canisters. In the grinder the coffee beans are ground through two metal blades to fine ground coffee. These two blades in the grinder are mounted horizontally. The upper blade in the grinder is a fixed blade and the lower blade is rotating, driven by a motor of 24VDC.

Grinder on canister plate grinder in door

By adjusting the upper grinder blade axially, the air gap between the two grinder blades can be set very accurately. This air gap defines the grain size of the ground coffee, what is known as the grinding degree. The grinding degree setting is made manually on a worm gear. The powder (ground coffee) is discharged into the powder outlet through four cams attached evenly around the circumference of the star shaft.

5.24 Grinder in door

The grinder is mounted in a housing fixed with hinges in the cabinet. By opening the door the grinder will rotate automatically and stay in the door. The grinder can be moved above the brewer for making a test drink with coffee from the grinder. In this case, unlock the grinder door with the green locking handle and rotate the grinder above the brewer.

5.25 Removing bean canister and grinder.

- Water/ingredient settings.

The water and ingredient dosage and other timings can be adjusted per available recipe. (see chapter 7.4.2 and 7.4.3 for detailed explanation)

- Strength control %.

The max strength difference from the medium dosage can be set. The medium dosage is the set dosage in the recipe settings of each individual consumption.

Example: For coffee and tea (this are main products) 5 strength steps are possible. If the main product strength is set to 10%: Every step means 5% more or less product. With this setting max 10% more or 10% less product from the average dosage is possible.

For milk (creamer) and sugar 3 strength steps are available. If the strength% is set to 30: Every step means 30% more or less product.

- Milk/Sugar available.

The milk or sugar option can be switched off. If switched off, the milk/sugar selection will disappear from the user menu.

- Selection available.

Every recipe can be available or not. If not available is selected the selection is not available in the user menu screen.

7.4.1 Water/ingredient settings

All available recipes are shown in the water/ingredient settings menu.

Select the recipe you want to change.

7.4.2 EXAMPLE: (Fresh brew) Coffee recipe in a bean to cup machine

Coffee = The settings for the ingredient fresh brew coffee. Press coffee, this gives a new screen: Delay = 0.0 means: Coffee is immediately dosed in the brewer, no delay. Duration = 2.5 means: The auger in the coffee canister rotates for 2.5 seconds, giving a certain amount of coffee in the brewer. Speed = 100 means: The auger rotates 100% (= full speed. )

In “Sub high pressure” is it possible to set the amount of water dosed in high pressure mode to give a nice crème layer on top of the coffee. Press sub high pressure to see the water amount for this part of the recipe.

Water amount (in main recipe) = the basis amount of water.

The water amount in the pressure boilers is adjusted in pulses generated from the flow meter. 1 pulse ≈ 0,8 ml Water amount 100 = about 80ml This coffee selection in this example exist out of 140(main recipe) + 40 (sub high pressure) = 180 pluses = 180 x 0,8 ≈ 144ml.

With the test button this recipe is dispensed in the service mode.

If there is also milk and sugar possible, the water amounts of milk and sugar are also added to the main recipe water amount if a black coffee is chosen.

Change a recipe setting:

1. Select the setting you want to change by

pressing the green button.

2. Enter the new value.

3. Press “Save” left under in the screen to

save the new setting.

7.4.3 EXAMPLE: Cappuccino recipe in a bean to cup machine

Beans = the duration time the grinder grinds beans.

3.0 means a duration of 3 seconds for the grinder.

Subr topping = the recipe for topping in the cappuccino.

- 1. Topping

0.5 in the first column means a delay of 0.5 (so

first there is water in the mixing bowl)

1.0 in the second column means a duration of 1.0

seconds for the milk powder motor.

- 2. topping

0.7 in the second column means a second topping

powder dosage of 0.7 seconds after a fixed, not visible delay. (Normally this delay is 0.5 seconds)

- Water amount = 100: The amount of water dosed through the topping mixer.

100 = 100 pulses.

Delay for UI release: Delay time at the end of the consumption, to delay the moment the machine is available for the next consumption. (also the “beep” at the end of a selection is delayed)

Water amount = the amount of water dosed through the brewer.

If there is also sugar possible, the water amount of sugar is also added to the main recipe water amount if a black coffee is chosen.

Change a recipe setting:

1. Select the setting you want to change by pressing the

green button.

2. Enter the new value.

3. Press “Save” to save the new setting.

7.4.4 Sub product milk and sugar

The sub products milk and sugar have their own water and product settings.

In this example: Delay = delay start dispensing product after start recipe = 0,5 sec. Duration = duration auger rotates, dispensing product = 0,7 sec. Speed = % of possible speed the auger rotates = 100%

7.5 Boiler temperature

Temperature setting gives the possibility to change the desired boiler temperature.

The default settings: Boiler 1: 90 = 90°C (194°F) Boiler 2: 92 = 92°C (197°F)

Show boiler temperature will show the actual temperature of the boilers in degrees Celsius or degrees Fahrenheit.

Boiler 2 is default set to 92°C (197°F). This value increases slowly automatically to 98°C (207°F) in about 20 minutes idle, to compensate a cold brewing system. As soon as a consumption is taken, the temperature setting decreases to the default 92°C. After the consumption is taken, the sequence of slowly increasing the boiler temperature in boiler 2 is starting again.

7.6 Cup sensor

Show cup sensor signal:

The signal of both sensors can be read individually. This way the visibility of a cup can be tested also.

Cup sensor setting:

The sensitivity of the cup sensor is adjustable. The value can be adjusted between 0 and 4000. The value 0 means switched off. In this case the machine works like there is no sensor. A higher value means less sensitive. So for detecting a transparent or dark colored cup the value must be set low. The default value is 100. This is the optimal value and gives the best detection for the most cup types. If there are two cup sensors in the machine, both are individual adjustable. Sensor 1 = Middle sensor. Sensor 2 = Right hand side sensor

Black cups or clear glass cups are not detectable, we advise to switch off the sensors if black cups or clear glass cups are used.

7.7 Language

Select the required active language. Depending on the configuration setup, a language selection is available. This chosen language is the default language for the user screen and the service program. DJD is the default English factory language.
