2MAIN FUNCTIONS
The MFC universal has two main functions: controlling heaters and controlling cooling valves. You
can control up to four devices (heaters or cooling valves) at the same time. This chapter describes
these two main functions.
2.1 Heating
VERMES MicroDispensing Systems can be fitted with a heater. With a heater, you can control the
dynamical viscosity of the fluid you want to dispense. For some fluids, dispensing without heating
is impossible. Heating may also be required to ensure a constant process temperature, or when the
dispensing has to take place above room temperature.
There are two main types of heater: nozzle heaters and cartridge heaters. With the MFC universal,
you can control those heaters. For some applications, e.g. hot melt dispensing, it works best to
combine both types of heaters. For a list of heaters compatible with the MFC universal, check
chapter 1.1.
Figure 2 shows one example, the MDFH 48-CC, connected with a MicroDispensing Valve.
The heater contains a heating element, to create the necessary warmth near the nozzle (see Figure
3, red part). To check the temperature, the heater also contains a Pt100 sensor (see Figure 3, blue
part). This allows the MFC universal to keep the target temperature near the nozzle.
Since there is a small but necessary distance between the sensor and the nozzle, in some applica-
tions might be a slight difference between the temperature measured at the Pt100 sensor and the
actual temperature at the nozzle. For those applications, you have the possibility to use a tempera-
ture correction. You can change the correction parameters for a channel in the menu of the MFC
universal (“Channel Settings -> Temp. Corr. Set.”, see chapter 3.7.3)or with the serial command
“CON:TCORR<channel no.>,<line of best fit gradient>,<line of best fit Y-axis intercept>,<save
YES/NO>” (see chapter 4.3.2). When the temperature correction is active, the display for the target
temperature will show additionally in brackets the value without correction.
We recommend you use the temperature correction only after you have fully understood the sys-
tem. You can find more information in the attachment 7.4.

2.2 Cooling
A VERMES Microdispensing Valve works best, if the temperature inside the valve stays below a cer-
tain limit. E.g. for the MDV 3250+this limit is at 80 °C for the actuator system and 39 °C at the out-
side of the valve body. For this reason, microdispensing valves can be fitted with an air-cooling
adapter (see Figure 4).
With the MFC universal, it is possible to control the airflow according to the temperature inside the
valve. This improves the dispensing accuracy and allows you to save compressed air costs.
To regulate the compressed air flow, the MFC universal controls a proportional compressed air
valve, the FCV Flow Control Valve (for an example see Figure 5). It regulates the airflow between
your compressed air supply and the microdispensing valve you want to cool.
At the same time, the MFC universal is connected with the sensor module of the microdispensing
valve via the Adapter Cable MFC, MDC and Sensor (see Figure 15)and receives the temperature
values from inside the valve. This grants the MFC universal the information needed to keep the
target temperature in the correct range by increasing or decreasing the cooling airflow as neces-
sary.
The compressed air connectors of the FCV Flow Control Valve are marked on one side, “1” is “IN” and
“2” is “OUT”. These connectors have 6 mm diameter. If you to want to connect the valve with a micro-
dispensing valve with 3 mm connectors, you need a 6 mm to 3 mm adapter.

The MFC universal has ten control lamps. The System Status control lamps are for the whole sys-
tem. The Channel control lamps and Status control lamps are numbered left to right from “1” to
“4”, as they are for one specific channel each.
Control lamp System Status (red):
This red LED flashes to show when there is an error. It is turned OFF again, once you confirm the
error by pressing the [enter]-key or by sending the serial command „SYS:ERR:QUIT”. This LED also
flashes once, if you press an incorrect key (e.g. the [enter]-key in a purely informational menu item,
which has no further sublevels, or if menu items are blocked).

Control lamp System Status (blue):
This blue LED is ON as long as the MFC universal is on. It always flashes quickly while pressing one
of the softkeys. It also flashes quickly, while a command is send via serial or LAN connection and
the MFC is in the top menu.
Control lamps Channel (orange):
These orange LEDs are ON to indicate the channel, which is selected in the menu. So only one of
these four LEDs can be ON at a time.
With service code 8310 (see chapter 3.7.2), you can also activate them to have a second function.
While you are in the top menu level, it will flash to indicate a channel is ON and using energy to
keep a temperature. The speed of flashing indicates the load percentage. You can deactivate this
function with service code 8300.
Control lamps Status (green):
These green LEDs have two different purposes, depending on your position in the menu:
1. While you are in the top menu level, they are ON while the device at their respective channel is
active (heating or cooling). Until the target temperature is reached, they flash (below the target
temperature with short flashes, above it with long flashes), then they are steady.
2. While you are in one of the channel settings menus, the LEDS are ON, if their channel is connect-
ed with a heater or a cooler.

For the connection of the Adapter Cable MFC and FCV for the respective channel. See Picture 8 for
an example of a 7-pin PCB connector. Pin 4 is the external pin. You can find the pin functions in
chapter 4.4.
4 x Sockets for Cable for Heater/Adapter Cable MFC, MDC and Sensor:
Four sockets for the connection with a heater cable for the respective channel or the Adapter Ca-
ble MFC, MDC and Sensor, if a cooler is connected. If you plug in a device, while the MFC is ON, but
the channel inactive, you get the message “Device Plugged In”. (In case the channel is active, you
get an error. See chapter 5.2.) You have to confirm the message with [enter]. If you unplug a de-
vice, you get the message “Device Plugged Out”. The display automatically jumps back to the menu
item “Act. Temp.” after a few seconds.

3.4 Function Keys
Each of the keys explained below has a keypad alarm. Pressing one of the keys creates a short
beeping noise, so you can hear if a key was pressed correctly. If you press the [enter]-key in a
menu, where it has no function, an alarm beep sounds. The same happens, if you try to turn ON a
channel without a device connected to it. You can turn the keypad alarm OFF in the submenu
“Beeper Settings” of the menu “General Settings”(see chapter 3.7.4).
Function Key Function
Pressing the [enter]-key confirms the menu selection and opens the corre-
sponding submenu or a page where a value is edited.
... or ...
Pressing the [enter]-key confirms the entry of a value, and the screen changes
to the next-higher menu level.
Note:
For the menu item “Channel ON/OFF” (see chapter 3.7.3)it makes a differ-
ence, if you confirm it with a short press of the [enter]-key or with a longer
press. If you confirm it with a short press, this is not saved internally and
therefore gets lost, once you switch off the MFC. If you confirm it with a long-
er press, the MFC saves this setting. It will be there, even after switching OFF
and ON the MFC.
Note:
Pressing the [enter]-key in a menu, where it has no function, leads to an alarm
beep.
Pressing the [esc]-key aborts the current action; values just entered are delet-
ed. The next-higher menu level opens.
... or ...
Direct access to the next-higher menu level. You will always jump back to the
menu item, from which you had entered the submenu.
... or ...
By pressing the [esc]-key for a long moment, you jump back to the menu item
“Act. Temp.” in the highest menu level.
... or ...
By pressing the [esc]-key you force a re-start, if you are in the bootloader
(usually only during a firmware update).
By pressing the [save]-key you confirm the entry of a value, and the screen
changes to the next-higher menu level. With this function it acts the same as
the [enter]-key.
With the [recall]-key you can retrieve the standard values for the cooler offset
and temperature correction settings, which are saved in the OW-EEPROM.
You have to enter the menu item for the channel and value you want to reset,
then you press the [recall]-key.
Press [enter] to confirm the selection.
Press [esc] to abort.
[↑]-key
By pressing this key, you switch between different settings of a parameter,
e.g. ON/OFF.
... or ...

... or ...
A parameter is modified.
[→]-key
The screen moves one menu step ahead.
... or ...
The cursor is shifted one position to the right.
... or ...
A parameter is modified.
[«]-key
By pressing this key you jump back one channel (4 -> 3, 3 -> 2, 2 -> 1, 1 -> 4), if
you are in one of the channel settings submenus, where you can change the
settings for a single channel. You stay on the same menu level as you were
before. This allows you e.g. to quickly change the temperature settings on all
four channels without having to navigate through the whole menu system.
[»]-key
By pressing this key you jump forward one channel (1 -> 2, 2 -> 3, 3 -> 4, 4 ->
1), if you are in one of the channel settings submenus, where you can change
the settings for a single channel. You stay on the same menu level as you were
before. This allows you e.g. to quickly change the temperature settings on all
four channels without having to navigate through the whole menu system.
In a menu item which shows minimum, maximum or mean values (e.g. “Heat-
er Load Mean Value” or “Act. Temp. Minimum”) the [F1]-key resets the start-
ing point for calculating these values, when pressed for a long moment. The
value is calculated and displayed anew from this point forwards.
By pressing the [F1]-key in the menu “LAN Info” for a long moment, you close
the current TCP connection (if there is one active).
Pressing the [F1]-key in the menu “Act. Temp.” shortly shows you the target
temperatures for a few seconds, whereas in the menu “Set. Temp.” it shows
you the actual temperatures.
Pressing the [F1]-key shortly in the submenu “Set Temp” of one the channel
settings directly sets the current temperature as your target temperature for
this channel.
The [F2]-key is only used in the top menu. When pressing it, the display shows
the name of the menu item again for a few seconds.

3.5 Beeper alarm
The MFC universal has not only an optical warning system with its LEDs, but also an acoustic one.
The acoustic warning system is the beeper alarm. The alarm beep sounds in the following situa-
tions:
•After start-up to announce the system is ready (short beep)
•When an error appears (continuous beep until you have confirmed the error)
•When during cooling or heating the actual temperature has reached the target temper-
ature (short beep)
•When connection or disconnecting a heater (short beep)
•When connection or disconnecting an MDV at the Y-cable (short beep)
You can switch OFF the beeper alarm in the submenu “General Settings -> Beeper Settings” (see
chapter 3.7.4). Select “Alarm Beep” with the [enter]-key and change it to “OFF”. In a new system
the beeper alarm is set to ON.
You have to distinguish the beeper alarm from the keypad alarm, which is explained in chapter 3.4.
You can turn them ON and OFF independently.
3.6 Setting up the MFC
This chapter describes how to set up your MFC universal and how to connect it with your VERMES
Microdispensing System. As example, we use a setup with one heater (channel 1) and one cooling
valve (channel 4). In Figure 9, you can see the schematic for this setup. You can find a larger version
of this schematic in the attachment 7.2.
Figure
9: Connection Diagram MFC (example with one heater and one cooling valve)

VTK-VS-BA-043e-C | User Manual MFC universal | Control Unit MFC universal
15
The control unit is designed as a 19” plug-in module, which has to be fixed in the corresponding
rack by means of four pan-head screws at the front side. Leave sufficient space around the unit to
simplify service. Ventilation should be available. Recommended are cases complying with enclo-
sures according to EN 61010-E with regard to fire protection.
IMPORTANT NOTE! (Potential damage to the MFC universal)
Do not close the four pan-head screws too tight; otherwise, the front panel can be damaged (rec-
ommended torque between 30 – 40 cN.m).
To avoid overheating and allow the required ventilation, you should ensure a minimum distance
between the control unit and any other object (at least 1.5 cm). Heat should not be accumulated
nor externally be introduced. Do not obstruct natural convection. Ventilation from the bottom side
and air exhaust above is important. Minimum width of ventilation openings is 8 cm x 8 cm.
Power connection of the MFC
The MFC needs an external power supply of 48 V DC. You have to connect this to the 4-pin PCB connector
(see Figure 10). The connection has to go to pins 1 and 4.
Heater connection
You have to connect the heater MDFH 48-CC (see Figure 11 with MDFH isolation body NAN-fix includ-
ed) with one of the Cable for Heater/Adapter Cable MFC, MDC and Sensor sockets at the bottom of the
back side of the MFC (see Figure 12). In most cases, it will be easier to screw the heater to your micro-
dispensing valve first. Push the plug in; then screw the connection tight. You should press the case
slightly forward while screwing.

CAUTION! (High temperatures)
The integrated heater can reach temperatures of up to 180 °C. Do not touch the nozzle area during
operation. Afterwards only touch it once it has cooled down.
Adapter Cable MFC, MDC and Sensor connection
If you want to use the MDV cooling, you have to connect the Adapter Cable MFC, MDC and Sensor (see
Figure 15)with one of the Cable for Heater/Adapter Cable MFC, MDC and Sensor sockets at the bottom
of the back side of the MFC (see Figure 16). The correct plug is the one from the longer end of the dou-
ble-ended cable (see Figure 17).
Figure
15: Adapter Cable MFC, MDC and Sensor
Figure
16: Adapter Cable MFC, MDC and Sensor connected

18
VTK-VS-BA-043e-C | User Manual MFC universal |Control Unit MFC universal
You have to plug the opposing end of the cable into the sensor socket of the MDC of your system (see
Figure 18).
You have to connect the shorter end of the double-ended cable with the sensor cable from the micro-
dispensing valve you are using in your system (see Figure 19).

Connecting the FCV Flow Control Valve
To connect the FCV Flow Control Valve (see Figure 20)with the MFC universal, you use the 7-pin PCB
connector of the Adapter Cable MFC and FCV for the channel. Picture 8 shows a 7-pin PCB connector.
Figure 21 shows the back side of the MFC universal with the 7-pin PCB connector. The connection is
with pin 1, pin 2 and pin 7.
The compressed air connectors of the FCV Flow Control Valve are marked on one side. An arrow shows
the flow direction. The connectors have 6 mm diameter. If you to want to connect the valve with a mi-
crodispensing valve with 3 mm connectors, you need a 6 mm to 3 mm adapter.

IMPORTANT NOTE! (MFC universal and channel ON before MDC)
If you are using a cooling system with the MFC universal, you have to switch ON the MFC and the re-
spective channel (see chapter 3.7.3 and chapter 4.3.2), before you can switch ON the connected MDC.
Otherwise, you would create an error at the MDC.
IMPORTANT NOTE! (Error when starting MFC universal)
In unlikely cases it can happen, that when starting your MFC universal, you receive the error message
“Firmware Error – Press Enter”. Press [enter] and try to restart the MFC. If the error remains, the firm-
ware has to be re-installed.
In this case, the firmware can only be installed with the MDC Upgradetool PICkit 3 (see User Manual
Firmware Update MDC Upgradetool PICkit 3). Contact the Technical Support of VERMES Microdispens-
ing (see page 4).
The next picture shows an overview of all the connections at the MFC universal (left) and the MDC
(right) for a system with one heater and one cooling valve. The connections have the following func-
tions (numbered clockwise):
1 Adapter Cable MFC, MDC and Sensor, connected with the sensor cable of the microdispensing valve
