1General
1.1 Introduction
The Barista Milk Mate is a simple beverage system for 2 lines that is usually used to dispense
different sizes of milk portions.
It is operated by using a graphical user interface with a touch screen.
An ergonomic PC application, the X5M MM Konfiguration, is supplied to conveniently configure the
controller unit. All necessary configurations can also be made directly at the controller unit via a
service menu.
The configuration of the device isn’t easily available for the customers. Only authorized persons
may change the settings: an adjustable, predefined code has to be entered for authentication.
1.2 Memory
A counter for each portion and some other events are logged in the background.
All data is stored in special non-volatile memory and thus can’t get lost even after a loss of power.

2.2 Connection of the supply
For supplying the device only direct current (DC) in the range of 12-24VDC may be used. This
voltage is also used to supply the valves!
2.3 Connection of the valves
Commonly available DC-valves or -pumps may be connected to the according outputs. Only valves
or pumps with a nominal voltage of 12 - 24VDC (according to the supply voltage) are to be used!
2.4 Connection of a PC
The device may be connected to a PC via USB for configuration purposes. Therefore the
configuration program has to be installed on the according PC.
A cable of type "USB-Mini-B <-> USB-A" has to be used for this connection!

2.5 Connection of a cash register
2.5.1 Bottom view of the electronics board
Use the highlighted connector (1) to connect a cash register via the optionally supplied serial RS-
232 cable (9 pole SUB-D).
The connector at the cable is wider than the connector at the electronics board to make it
impossible to connect it reversed (in this case it would hit the solder joint next to the connector)!
Prevent the cable from unintended disconnection by proper means, e.g. by using a glue to fix it to
the printed circuit board!

3Operation
3.1 General operation
The operation of the Barista Milk Mate is solely done via the touchscreen.
The main menu can only be entered when using a proper code (see chapter "3.5 Code input")!
3.2 Switching on the device
The Barista Milk Mate is switched on by connecting the power supply unit to the power grid.
3.3 Standby
The standby screen shows the chosen picture (menu "Settings"
–"Standby image").
Normally the standby screen is shown after a certain amount of
time (see general setting "Standby timeout" in the
configuration) when no action happens meanwhile.
If the standby screen is touched then the desktop is shown (see
below).
3.4 Desktop
At the Barista Milk Mate a maximum of 4 portions may be
stored, which are chosen via the 4 product buttons.

Manual Barista Milk Mate 1.5
© La Cultura Del Caffè GesmbH 04.09.2015 Page 8 | 36
3.4.1 Dispensing of portions
By touching a button the according portion is dispensed. During
this action a "Play"-sign is shown at the button.
If the parameter "Aborting possible" is set to "yes", the actual
dispensing of a portion (even if it is paused at this moment)
may be stopped by touching the title bar (see the blue framed
area at the picture to the right). Even when a portion is stopped
this way the reporting counter for this portion is incremented!
ATTENTION:
If "General settings –Serial interface –Type" is set to be a cash
register interface, the dispensing of a portion only starts if the
cash register allows the request. In the meanwhile the button is
shown as being pressed, but without the “Play”-sign mentioned
above! If the cash register denies the request, the button is
again shown in its normal state.
If a button is touched again while a portion is dispensed (the
"Play"-sign is shown) and if the parameter "Pausing possible" is
set to yes, a "Pausing"-sign is shown at the button and the
portion is paused.
If the parameter "End pause automatically" is set to be 0, the
pause needs to be ended manually by touching the button again
–then the "Play"-sign is shown and the portion is resumed.
If the parameter "End pause automatically" is greater than 0,
the pause will be ended automatically after the given time
expires. During this time the "Pausing"-sign is filled up slowly
with the color of the "Play"-sign.

3.4.2 Reporting at the buttons
If the option "View reports without login" is set to yes, the
report counters for each portion are shown when touching the
title bar (see blue framed area in the picture to the right) for
about 3 seconds.
By doing so, a rectangle (using the style of the title bar) is
shown at the bottom edge of each button to show the actual
report counter for that button/portion.
It is shown as long as the screen is touched again to return to
the usual desktop screen.
3.5 Code input
The menu "Code input" is entered by touching and holding the
title bar (see blue framed area in the picture to the right) for at
least 5 seconds.
ATTENTION:
If the option "View reports without login" is set to yes, the
report counters at the buttons are shown after 3 seconds. In
this case KEEP touching the title bar without interruption to be
able to enter the menu "Code input"!

Manual Barista Milk Mate 1.5

Then the screen for the code login appears.
Enter the code via the numbered buttons and confirm via the
button "√". Alternatively the code input may be cancelled via
the button "X" in the title bar.
During code input each number pressed is shown by a "*" in the
title bar.
After the correct code is confirmed the main menu is shown
(see below).
3.6 Main menu
If a proper code has been entered and confirmed during the
code login, the main menu is shown:
"Reporting" shows the report counters for each button/portion.
The "Event memory" displays (chronologically) different events.
"Settings" is used to configure the device.
The "Service" menu is used for some calibration and test
routines.
3.7 Reporting menu
At the reporting screen the counter for each button/portion is
shown. It shows how often a button was pressed since the last
reset of the according counter.
ATTENTION:
Counters for buttons with "manual portions" (button not inactive
and time of each sequence is 0,00s) are also incremented each
time the button is pressed, but keep in mind that due to the
variable portions in this case it is not possible to deduce the
dispensed volume of the according beverage!

Manual Barista Milk Mate 1.5
© La Cultura Del Caffè GesmbH 04.09.2015 Page 11 | 36
To reset a counter choose the according button/portion in the
menu (it is marked with a red sign then, see picture).
The button "Reset counter" will become active if at least one
counter is chosen to be reset!
After pressing the button "Reset counter" a new pop-up window
appears to either confirm or cancel the procedure.
If the reset procedure is confirmed, the chosen counters are
reset to 0 and again all counters are shown in the menu.
In the example shown to the right the counters for button 1 and
button 2 were reset.

3.8 Event memory menu
The last 100 events are shown chronologically in a list.
Select an entry by touching it.
If details are stored for the selected event, the button "Details"
is activated to allow the user to see further, detailed data.

3.9.5 Buttons Portions
By using this menu each one of the 4 possible portions may be
set.
Press one of the buttons to set its portion.
Each portion consists of 2 sequences. The sequences may follow
each other sequentially or may run simultaneously. Every
sequence opens its valves for the time set.
Usually the portioning for each sequence is done by first
choosing the valves for this sequence (they are marked red
then). Then press & hold the button to coarsely set the
time for this sequence. Then the time may further be adjusted
by using the buttons "+" or "-".
If the function "1=2" is set (marked red), both sequences will
start simultaneously. If "1=2" is inactive, at first sequence 1 is
started, afterwards sequence 2 is started.
By pressing the "Test" button, the actual portion is dispensed for
verification purposes.
Confirm and store the new portion using the button "√" or
cancel using the button "X" in the title bar.
The example shown in the picture at the right hand side means
that the sequences are started simultaneously ("1=2" is
activated), so valve V1 and valve V2 are opened at once. After
1,00s V1 is closed, 0,30s later V2 is also closed (it is opened for
1,30s overall).
Manual portion:
If the valve time of both sequences is set to 0,00s and the
according button is not inactive, the dispensing lasts as long as
the button at the desktop screen is pressed. The according
valves may be set either in sequence 1 or sequence 2
Note:
If during portioning via the button no valve is chosen
(neither area "V1" nor area "V2" activated), the portioning can
be done without opening a valve. In this case at first the time is
set and afterwards the according valves for each sequence are
chosen.
