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.

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.
18
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.
9. Ready
Part number pressure reducer: 4MVL010
Looking from above: Turning clockwise = increase output pressure
Turning counter clockwise = decrease output pressure
19
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.

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.
plunger
coil
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.

Heater:
The boiler has a 1,4 KW/240VAC heater or a 1,1KW/110VAC. The volume in the
boiler is 0,36 liter.
The boiler and heater are made of stainless steel. The heater is welded in the top
of the boiler.
The winding resistance of the heater is:
Heater
resistance
1400W 240VAC 39 - 40Ω
1100W 120VAC 12 – 13Ω
The heater is controlled by the control system. This is based on a combination of
detected temperature by the temperature sensor and the amount of incoming
water by the flow meter.
24
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
95ºC
100 k
25ºC
126.7 k
20ºC
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
25
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 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.
12 bar safety valve
2 bar pressure valve
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.

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.
38
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.

5.22 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.

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.

Recipe settings
- 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.
65
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.
66
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.
67
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.
68
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.
