1INTRODUCTION
With a micro dispensing of the MDS 3000 line from Vermes Microdispensing you have bought a
high quality product. Due to the long-standing experience of the team in regards to electronic de-
vices and piezo controls, these products provide highest functionality and reliability.
Thank you very much for your trust in us.
We will now show you how to assemble and use the microdispensing system. In order not to im-
pair the inherent safety concept of the system, procedures described in this manual have to be fol-
lowed consequently during installation and operation.
Read this manual before you start the assembly and always consult it during the use of the
microdispensing system. Start with the chapter “Safety Notes” (see page 11). This will help to pre-
vent any problems for the user or the equipment. In the case of further questions, consult our

The MDS 3000 Product Family
The MDS models are members of the MDS 3000 product family, specialized in most accurate dis-
pensing and designed for flexible use with substances of low, medium and high viscosity (up to
2.000.000 mPas).Applications can be found in the fields of SMT and in the production of electron-
ics, semiconductors and photovoltaic modules and many more.
Each microdispensing system belonging to the MDS 3000 product family is composed of a high pre-
cision valve based on a piezoelectric element (MDV series), a control unit (MDC series) and an op-
tional selectable supply unit.
Due to its compact modular design, the system can be integrated quickly into any existing produc-
tion environment without major preparatory work. A change in the production line (e.g. a modifi-
cation of the liquid to be processed) is easily possible, since all of the dispensing parameters are
adjustable in a large range. Fine-tuning of the sequence is therefore possible at any time. The sys-
tem allows for reproducible proportioning of hundreds of identical single dots (0,3 nl up to
> 200 µl)or beads within a few seconds.
A comprehensive choice of accessories is available, e.g. nozzle inserts, tappets, seals and supply
units, so that the system can easily be adapted to new challenges any time, without giving rise to
major investment.
Valves compatible with MDC 3200+
The base of each Microdispensing System of the MDS 3200+series is the control unit MDC 3200+,
which is then combined with a valve. This can be any valve of the series MDV 3200A or MDV
3200F. This is a complete list:

3.5 Warnings
•Handle the mains cables correctly: Always seize the cable at the plug. Never touch it with
wet hands.
•The cable should never be squeezed or kinked. Never place the instrumentation (or any
other object)on the cable.
•Damaged cables may give rise to fire and danger caused by electricity. Inspect them vis-
ually in regular intervals. Damaged parts should be exchanged at once.
•In the case of a major disturbance, disconnect the equipment immediately from the
mains.
•Spare parts not delivered or recommended by the manufacturer could affect the inher-
ent safety of the system. The same problem arises, if the customer attempts to process
substances not admitted for the dispensing system.
•Unqualified repair work often causes major damages, sometimes even personal injuries.
Therefore repair is reserved to our Technical Support and authorized subcontractors.
•Before removing the actuator and sensor cable, the system must be switched OFF.
•For longer interruptions, switch OFF the control unit.
•Before disconnecting the MDC 3200+from the mains, switch it OFF.
•Repeatedly switching ON and OFF the equipment may reduce the lifetime of the power unit.
•Before charging the fluid system with an aggressive, reactive or toxic substance, it must
be verified that it is compatible with all of the contacting components inside the system.
•The supply pressure at the cartridge or in the pressure tank of 7 bar resp. 100 bar (accord-
ing to the system configuration) should never be exceeded.
•If you use the MDV with a heater for the nozzle unit, the temperature in that area can
reach up to 120 °C. Do not touch it during operations and afterwards only once it had
enough time to cool down.
•When cleaning the components in contact with the transported substance, the device
should be placed in a safe and stable position, without being subjected to vibrations.
•To clean the actuator, a cloth not fluffy and lightly moistened (e.g. by Isopropanol)is rec-
ommended. During the cleaning procedure, no liquid should penetrate into the actuator
itself (e.g. through the plug).

VTK-VS-BA-015e-A | User Manual MDS 3200+ Series |Safety Notes
•The MDV 3200 series is designed according to the Normally Open principle. Therefore
the valve is normally open and the transported liquid can flow. Before switching OFF the
microdispenser, do not forget to lower the supply pressure to atmospheric pressure.
3.6 Qualifications of Operators and Maintenance Personnel
The microdispensing system together with all attached accessories should only be used by compe-
tent personnel with an adequate qualification. They must know and understand the content of the
manual. We do suppose that the department head is aware of possible dangers, and correspond-
ingly assigns the tasks to persons able to execute their work in a responsible manner.
According to DIN VDE 0105 and IEC 364 qualified personnel refers to members of the team with a
sufficient knowledge of relevant norms, directives and rules for prevention of accidents. They need
the qualification and experience necessary, so that they are in a position to realize and to prevent
possible dangers already at an early stage. Knowledge in First Aid and a direct contact to the local
emergency units is required as well.
3.7 Protective Equipment and Safety Clothing
You should always wear suitable protective equipment, whenever handling or dispensing aggres-
sive, reactive or toxic substances. The same is valid in the presence of a high supply pressure.
This may comprise:
•Safety glasses
•A breathing apparatus
•An overall and gloves resistant to the corresponding chemical fluid
When you work in the direct vicinity of the MDS for a prolonged period, you
should also wear ear protection.

This key opens the valve, taking into consideration the current values for “Ris-
ing” and “Falling”. The valve remains opened until the key is released. Maxi-
mum length: 2 min. Then the valve closes automatically in order to protect
the actuator.
If you start the control unit, while holding the [F2]-key, you are given the op-
tion to format the EEPROM. With [enter] you agree, with [esc] you skip this
point and reach the main menu just as normal. This function will only be nec-
essary in exceptional cases.
IMPORTANT INFORMATION!
Settings for Scenarios will not be reset back to the factory settings. That is
only possible with the options “Scenario” and “Reset ALL” after entering the
service code 1000 (s. chapter 4.1.5.7).

4.1.5 Menu Structure
The main menu of the control unit MDC 3200+contains 6 submenus: “Pulse Parameters“, “Heat-
ing“, “Status“, “F-Valve”, “Scenario” and “Service-Option”. With the [enter] key you can reach the
level of the submenus. There you can switch around with the keys [arrow right] and [arrow left].
Another option from the main menu is to use [arrow right] or [arrow left], which allows you to
gather some information about the system, like maintenance situation or ID numbers. The items
are “Tappet”, “Nozzle”, “Date”, “MDC ID”, “Valve ID” and “Firmware Rev.” “Firmware Rev.” will
give you the current revision of the firmware on your MDC. “Date” gives the current date and time
(as UTC), if your MDC has a Real Time Clock (RTC). With [arrow up] you reach a level, where you
can find information about the frequencies of your setups or scenario (depending on, if scenario is
“ON” or “OFF”). Menu levels are always “wrap-around”, i.e. you can move on from the last item in
a menu directly on to the first. With [escape] you can change from a sub menu into the next higher
menu level.
INFORMATION! (Dispensing frequency/valve type)
In the upper right corner of the display you can always see the dispensing frequency which would
result from the working parameters. Switching the setup via select pins doesn’t change the display.
Only if “Scenario” in the submenu “Scenario” is turned “ON”, the display will show “Scenario” in-
stead.
The main menu shows an “A” or “F”, to indicate the operating mode used by the MDC. “A” is
shown, if an F-valve is used in A-mode (see chapter “Service-Option” 4.1.5.7)or it is an A-valve. “F”
is used for an F-valve in F-mode.
IMPORTANT NOTE! (Menu “F-Valve”)
The menu item “F-Valve” will only be shown, if there is actually a valve of the F series connected to
your MDC. If the F-valve is in A-mode (see chapter 4.1.5.7), you can still see and use the functions
of the menu “F-Valve”.
•Dispensing parameters for a particular process can be recalled and modified in the sub-
menu “Pulse Parameters“.
•“Heater“ – select the settings for the heating.
•You can use the submenu “Status“ to decide on individual cycles for the replacement of tappet
and nozzle insert (see page 98). The current state of the system with respect to the mainte-
nance interval can be verified by the function “Maint. Cycle“ (see page 98). With “Maint. Mes-
sage” you can decide to show maintenance messages or not. Error messages concerning the
system are shown with the function “Error“.
•The submenu “F-Valve” will only be shown, if there is actually a valve of the F series (MDV
3200F or MDV 3200F-HS)connected to your MDC. Here you will find those functions with a di-
rect relation to the special features of this valve type.
•In the submenu “Scenario” you can enter values for pre-defined scenarios. Here you can also
set the option to work with these scenarios.
•The submenu “Service-Option” is used to enter service codes and to change the baud rate.
