Structural components
6.1 Coffee grinder
The service life of the grinding wheels is approx. 80.000 grinding processes (1
grinding process = approx. 10 g). The grinding capacity on the finest setting is
approx. 180 g/min, i.e. roughly 3 g/s. The grinding capacity decreases as the
wheels begin to wear down.
The grinding process is timer-controlled, which means that less ground coffee is
dispensed as the grinding wheels begin to wear down. The reduced grinding
capacity can be compensated by increasing the grinder running time (parameter:
ground coffee quantity). If the grinding capacity is severely reduced, the grinding
wheels must be replaced.
6.1.1 Adjusting the grinding fineness
. Set the ground coffee quantity and grinder running time to the standard value.
Disconnect the machine from the mains!
Adjusting the grinding wheels
Adjusting ring
Catch
. Release the catch.
. Tighten the adjusting ring until the upper grinding wheel touches the lower
grinding wheel.
. Turn the adjusting ring back a notch.
Upper
(fixed) grinding wheel
Cap nut
Lower (rotating)
grinding wheel
. Grasp the cap nut and turn the lower
grinding wheel manually through at
least 1 complete revolution.
There should no longer be any rubbing sounds: otherwise, turn back another notch.
Then perform the following setting for
the coffee type.
Settings for coffee type
After adjusting the grinding wheels:
- Instant coffee = turn back approx. 12 notches
- Cafe Crème = turn back approx. 10 notches,
- Espresso = turn back approx. 10 notches.
. Carry out test run.
. If necessary, correct the setting on the coffee grinder: loosening the adjusting
ring (i.e. turning anti-clockwise) causes the beans to be ground more coarsely (please note that the ground coffee quantity increases accordingly).

6.2.1 Operation of brewing unit
Calibration process
Photoelectric barrier for measuring
distance travelled
(encoder)
The brewing group is calibrated every
time the machine is switched on. This involves measuring the upper and lower
limit positions of the plunger, then calculating and storing the distance between
the two.
Go to photoelectric barrier
for reference
point
Procedure:
Upper brewing
plunger with
needle filter
2. Brewing plunger moves all the way
down to record the bottom limit position. At the same time, the distance
covered is recorded via the perforated disc and encoder.
Ground coffee
funnel with
wiper
Brewing bush
Lower brewing
plunger with
strainer
1. Brewing plunger moves upwards to
determine the upper limit position (reference point) and is wiped at the
same time.
3. Brewing plunger moves upwards
then back to the home position (ready
for brewing; ground coffee funnel in
filling position).
Using the stored data, the control system
is now able to move the ”upper brewing
plunger” to each desired/programmed
position:
e. g. to the positions ”Fill with ground coffee”, ”Brew coffee”, ”Compress ground
coffee” or ”Wipe off coffee grounds”.
Service instructions bremer VIVA, issued 1997-07 Status: 2003-03
6-5
Brewing sequence
After having pressed the product key:
1. Coffee is ground and falls into the brewing cylinder.
2. ”Upper brewing plunger” moves down until it is a set distance away from the
”lower brewing plunger” depending on the required article.
The machine checks whether the metered quantity of ground coffee is sufficient by attempting to recompress it with the ”upper brewing plunger” at reduced motor power( ”bean container empty” signal).
The grinder of the assigned product keys gets blocked.
After refilling the bean container and deleating the blocked product keys by
pressing one of them more than 5 seconds they are again usable. The next 2
products after deblocking are not checked if there is enough coffee dispensed.
3. Brewing water is metered.
4. ”Upper brewing plunger” recompresses the ground coffee in order to to dry it.
5. ”Upper brewing plunger” and ”lower brewing plunger” move upwards, thus
automatically actuating the wiper. The coffee grounds are scraped off into the
grounds container.
6. Brewing plunger moves to the home (i.e. filling) position.

Automatic cleaning of brewing unit (duration: approx. 5 minutes)
After confirmation that the cleaning tablet has been added:
1. The ”upper brewing plunger” moves down into the brewing cylinder and closes the brewing chamber.
2. The brewing cylinder is filled with hot water. A reaction time of approx. 60
seconds then ensues during which the cleaning tablet is dissolved.
3. 4 rinses are carried out under pump pressure, using approx. 70 ml of hot
water each time. The detergent solution is pumped through the coffee-carrying pipes into the coffee dispenser.
4. The ”upper brewing plunger” moves to the lower imit position to squeeze out
the remaining detergent solution.
5. 4 rinses are carried out under pump pressure with clear hot water. For this
purpose, the ”upper brewing plunger” moves upwards slightly and hot water
is pumped in. Afterwards, the ”upper brewing plunger” moves down to the
lower limit position to squeeze out the remaining water.
6. The machine switches off automatically (standby).
7. When the machine is switched on again:
- the brewing unit is calibrated,
- the brewing water and hot water/steam boilers are heated up,
- a brewing cycle takes place to neutralise the brewing unit and coffee-carrying components. The neutralisation results from the setted values of the
article key one (left hand side the first).

Notes Cleaning
If the automatic cleaning sequence is interrupted by switching off the machine or
disconnecting the power supply, it is resumed as soon as the machine is switched on again and the command ”Add cleaning tablet” appears. The automatic
cleaning sequence must be completed.
If, during a working time of 24 hours, cleaning has not been carried out the display box will show the request “Clean machine”.
If, despite this request, the machine is not cleaned the display box will show the
command “Add cleansing tablet“ after another 26 hours thus forcing a cleaning
cycle.
6.2.2 Maintenance of brewing unit
The brewing unit must be serviced
- after approx. 60 000 brewing processes,
- at least once a year.
Maintenance comprises:
- replacement of wearing parts such as O-rings, strainers, etc. or

6.8 Brewing water boiler
6.8.1 Operation of brewing water boiler (installed on left-hand side of machine)
Brewing water boiler:
1. For preparing hot water for all types of coffee.
- Brewing pressure for coffee approx. 0.4 - 0.6 bar: the pressure for the
brewing water is reduced via the nozzle (1.2 mm dia.) in the flow sensor.
- Brewing pressure for coffee types espresso, schümli and cappuccino
approx. 8 bar. The pressure for the brewing water is increased via the
motor-driven pump.
2. For dispensing hot water in machines without a hot water/steam boiler. In
these models, it is not possible to brew and dispense hot water at the same
time (interlocked functions).
The water is supplied to the brewing water boiler
- from the pressure regulator,
- by the motor-driven pump M1,
- via the flow sensor B4,
- via the check valve.
The boiler pressure in the operational state is 2.6 - 10 bar.
When hot water is dispensed from the brewing water boiler, more cold water
is automatically supplied.
The temperature is controlled via the NTC temperature sensor B1.
Filling the brewing water boiler
After opening the on-site water valve:
- Cold water flows into the brewing water boiler until a pressure of 2.6 bar
is built up. A previously empty brewing boiler (initial filling) is now filled
with water to approx. 2/3 of its capacity.
After switching on the machine:
- The control system checks whether the flow meter is emitting impulses.
- If the flow meter is no longer emitting impulses, the brewing unit moves to
the brewing position.
- The brewing valve opens and remains open until the flow meter has measured a suitable number of impulses (predetermined by the control system). During this time, any air present in the brewing water boiler escapes. The supplied quantity of water is sufficient to fill the boiler completely
(including initial filling). Any excess water flows out of the coffee dispenser.
- The heater of the brewing water boiler is switched on and heats the water
to brewing temperature. From 80°C upwards, the article keys are
released for coffee-making.

6.9 Hot water/steam boiler
6.9.1 Operation of hot water/steam boiler
(installed on right-hand side of machine)
Hot water/steam boiler:
1. For dispensing steam and hot water.
2. For frothing or heating up milk.
The water is supplied to the hot water/steam boiler
- from the pressure regulator,
- via the check valve,
- via solenoid valve Y2.
The boiler pressure in the operational state is approx.1.3 bar.
The water level in the hot water/steam boiler is controlled by the electrode.
The NTC temperature sensor B2 enables hot water, steam and milk products
to be dispensed from a temperature of 110°C upwards.
The temperature is regulated via the pressure switch.
Filling and heating process of hot water / steam boiler
When the machine is switched on, the boiler heating is deactivated until the electrode is moistened with water for the first time (automatic filling during initial startup).
If the electrode is not moistened with water within 200 seconds, the control system switches off the hot water/steam boiler and locks the corresponding article
keys. In standby mode, the error code 02 is displayed.
If the machine is switched on again, the boiler filling procedure is repeated. Once
the electrode is moistened with water, the heater switches on. The solenoid valves for hot water and steam dispensing are open, and close when a temperature
of 85°C is detected by the NTC temperature sensor.
Limit values for hot water / steam boiler cut-off
- For first filling: If the electrode is not wetted with water within 200 seconds.
- For first filling: If the releasing temperature of 110°C is not reached within
7 minutes.
- During operation, after having taken hot water: If the electrode is not
wetted with water within 240 seconds.
Service instructions bremer VIVA, issued 1997-07 Status: 2003-03
6-28
Ventilation of the hot water / steam boiler
Ventilation during the heating process:
- The magnetic valves Y4 for hot water, Y6 for steam and Y5 for milk foam
are left open for ventilation of the hot water / steam boiler until the temperature of 85°C has been reached in the boiler.
Ventilation for cold pressure:
- The magnetic valve Y5 is opened for a period of 0.5 seconds if temperature has fallen below the releasing temperature of 110°C and temperature
has not gone up for a period of one minute.
Topping up with cold water during dispenser of hot water
Topping up with cold water during dispensing of hot water (to avoid excessive
splashing): when the hot water dispensing solenoid valve Y4 opens, the level in
the hot water/steam boiler falls. The cold water supply solenoid valve Y2 then
opens, allowing cold water to flow into the boiler and, at the same time, via a
nozzle to the hot water dispenser.

6.19 Coffee dispenser with frother head
6.19.1 Operation
The prepared coffee flows through the dispenser block.
The milk frother for producing hot milk or milk froth is integrated in the dispenser
block.
The dispensed quantities of coffee and milk/milk froth are divided in the dispenser rocker, thus allowing 2 cups to be filled simultaneously.
The coffee dispenser is locked when the dispenser block is pulled out. The pin
on the dispenser block actuates the microswitch on the holder guide.
Production of milk froth
The steam solenoid valve Y5 opens, allowing steam to flow through the dispenser block while milk is simultanously sucked in (injector principle). Via the air
nozzle air passes through the pressure equalising chamber and mingles with the
milk and steam to produce milk froth. The milk froth flows into the frothing chamber, settles and then flows out again.
Production of hot milk (option)
The steam solenoid valve Y5 opens, allowing steam to flow through the dispenser block while milk is simultaneously sucked in (injector principle). Solenoid
valve Y7 is switched to prevent the entry of air. After being heated by the steam,
the milk flows into the frothing chamber, settles and flows out again.

10.8 Prevented Service for Brita water softener
The pulse trigger of the water gauge can be connected
− on the 5 pole connectionbenave the connection of the hot water outlet
− PIN 1 + 5
− Required 5− pol. plug (Id.Nr. 094196).
description of the system
To prevent calcification on coffee machines, Britta Waterfilters are placed into
the water supply of the coffee machines. The Problem is, that they have a
limitted throughput rate and they have no efffect anymore to soften the water.
The Flowrate is dependent from different factors. f.e. from the water hardness in
the area. Therefore is to each brita filter a table enclosed, how much water, at
which water hardness can run through the filter before it has to be changed.
Now you get a message in the display of the Coffee machine, if the water filter
needs to be exchanged.
Function
Therefore you have a preselected counter from 00 000 to 99 999 .unit = Liter
(realistic values are between 3000 and 50 000 Liter ). With a parameter in the
Service menue You can preset the counter to the Value which you need with
your filter and water quality.

In the new PC board we have for controlling the device applications a 32 Bit
processor inserted. The Neuronchip is just used for the communication of the
LON−Network
programmdownload
Communication in the network (f.e. VIVA with MDB Interface).
The APB−File for the Neuronchip is downloaded by the manufacturer and has
just to be downloaded new, when there are changes in the ntework interface via
ALEX (like untill now).
The Applicationprogramm (machineprogram) exists out of 4 blocks.They are
zipped in a file and get automatic unzipped by a download start and after a
programdownload again deleted – the zipped file remains. The name of the
zipped file is the name of the Software Version
f.e. VMK_0501_22.zdl
The Firmware of the control board includes a program named Bootloader. It
corresponds the BIOS of a PC. It is downloaded by the manufacturer and will be
automatical installed by a download of the applicationprogram with
plugin(improvement).
The Bootloader will be started first by switching on the PC board.
The Bootloader has following jobs:
1.Intialising of Hardware components (processor, memories – not In and
Outputs)
2.Check of the applicationprogram (checksum)
3.Start application
If the application test is negative the machine application will not be started.
LED of the product keys will flash.
The applicationprogram must be new downloaded.
The Bootloader is starting a LON−Application to make a LON−Communication
possible. This application, which is part of the bootloader program, is also used
by the PlugIn by downloading of the applicationprogram.
When the application is started, the bootloader is not any more required.

10.11 Functional Description VIVA au lait, Type 810 . . .
Functional Description
The VIVA au lait has two valves more than the VIVA standard design. The single
solenoid valves sit in contrast to the standard design directly on the hot
water/steam boiler. The steam valve Y8 is used additionally for the heating up of
milk and provides for an optimal expenditure temperature of approx. 71 degree
C, for the product milk.
The additional steam pipe waives the Injectorprinzip. Thus independent sucking
in of the milk is no longer possible. In the milk refrigerator is a pump, which
promotes the milk to the expenditure head. The steam valve Y9 is in each case
always needed for free blisters of the milk pipe by milk remainders, after the
expenditure for product.

During requirement of milk foam, e.g. for Cappuccino, Valve Y5 opens and
leaves steam I into the expenditure head, in order to warm the milk up. Air for
milk foam is sucked in as with VIVA standard machine design over Valve Y7.
After expenditure for product Valve Y5 switches off. The pressure drop takes
place from Valve Y5 by means of the feeder pipe and Valve Y8 into the steam
pipe II.

Functional description
The VIVA au lait has two more valves than the VIVA standard-model. As
opposed to the standard model, on the VIVA au lait the magnetic valves are
seated directly on the boiler.
This results in a significant reduction of condensation build-up. The steam valve
Y9 is for blowing the milk pipe clear of milk residue, always after dispensing the
product.

After dispensing, product valve Y8 drops out. Then shortly after the dropout,
valve Y5 lets in steam via connecting pipe / valve Y8 and blows out steam pipe
II.
No air suction (valve Y7) is required for milk products. Air valve Y7 only opens
for products with Milk foam (for example cappuccino) to froth the milk with air.
