General
This operating manual contains all necessary instructions for the installation, commissioning, operation and
maintenance of the mp6-XOEM. The manual is intended to help you achieving optimal results in a short time and
shall also assist avoiding possible sources of errors. The operating manual of the other controllers, micropumps and
the accessories are available separately.
The products have been designed with state-of-the-art technology and in accordance with all relevant safety
regulations. However, a risk of damage to the units, other property, the operator and/or other persons cannot be
fully excluded.
Always ensure that specialized and trained personnel will comply with the following general instructions.
Therefore, please keep this manual and hand out copies as required.
Bartels Mikrotechnik GmbH rejects any responsibility for damages to persons or property resulting from non-
compliance with the instructions in this manual. In this case all warranties shall be void.
Declaration of conformity
Bartels Mikrotechnik GmbH declares that the products are compliant to the RoHS directive 2011/65/EU. The
controller complies with the requirements of EMV 2014/30/EU and CE markings have been affixed to the devices.
Additionally, the controllers are also compliant to the EU Low Voltage Directive 2014/35/EU.
Description of functions
The micropumps have been developed for the transport of gases or liquids. The controllers have been developed for
operating the micropumps. Bartels Mikrotechnik can assume no liability for damages resulting from the pump
media. This applies especially for hazardous fluids.
The pumps must be operated with Bartels Mikrotechnik electronics. Bartels Mikrotechnik GmbH cannot guarantee
the proper work of the units with customer specific electronics. If other controllers than the ones from Bartels
Mikrotechnik are used, Bartels Mikrotechnik disclaims any warranty.
Moreover, please note that components of the controller and pump are operating with high-voltage. Therefore,
persons wearing pacemakers are recommended to avoid the operating system.
Bartels Mikrotechnik assumes no liability for abnormal handling, improper or negligent use of the micropump and
the controller that is not conform to the specified purpose of the system. This applies especially for micropump
controllers, components and systems of other manufacturers, which have not been certified by Bartels
Mikrotechnik.
We guarantee that the micropumps comply with the actual state of scientific and technical knowledge hence the
operational risks are limited to a minimum.
Do not open the housing of the micropump and the controllers.In those cases, Bartels Mikrotechnik cannot issue a
guaranty anymore. Please keep this manual safe and give a copy to all users.

The mp6-XOEM controller
The mp6-XOEM is a small, easy to use driving circuit developed for the micropumps of the mp6-series especially
the mp6-liq as it delivers a 200Hz signal at full amplitude as a default signal. It generates amplitudes up to
250 Vpp from a 3-5 V DC supply.
Its low power consumption makes it ideal for battery powered handheld devices or even solar powered devices.
The module can be integrated into a PCB design as an 18 pin DIL package.
The build-in interface allows the user to adapt frequency, amplitude and signal-shape to its application by the use
of a few additional components or a microcontroller.
In order to locate Pin 1, please refer to the following figure. The pin is marked with a colored spot or triangular
marking on the corner of the PCB.

Connecting the micropump with the mp6-XOEM
The micropumps of the mp6-series can be connected with the mp6-XOEM via a FCC connector. More information
concerning this connector and the pin layout of the micropump can be found in manual of the micropump mp6-
series.
DANGER!
The output of the mp6-XOEM carries high voltage!
Only plug in the micropump when the mp6-XOEM controller is unpowered or
switched off

Examples of circuiting the mp6-XOEM
Operation with fixed settings
The mp6-XOEM can operate the micropumps of the mp6-series without further external components. In this case,
frequency and amplitude to the micropump are predefined to 250 Vpp and 200 Hz by the internal circuit.
Schematic 1: Predefined amplitude of 250 Vpp and frequency of 200 Hz by internal circuit.
Operation with variable settings via external components
In this example, amplitude to the micropump will be defined by external components. The amplitude can be varied
in the range from 0 Vpp to 250 Vpp.
Using a voltage divider it is possible to set the amplitude with only two additional resistors. See image
“Schematic 2” below for an example. First picture shows two resistors generating the reference voltage for the
AMP-pin. The voltage at the AMP-pin can be calculated with this formula:

VV DDAMPLITUDE  
As an alternative an appropriate potentiometer can be used to adjust the reference voltage. On the second picture
a potentiometer and an offset resistor are used to generate the reference voltage for the AMP-pin.

Rev. 1.2 (04.2020)
Schematic 3: Defining amplitude with external components.
The relation of the voltage at the AMP-pin vs. the output voltage is shown in the picture below. It shows a gain of
approx. 200:1 between reference voltage and output voltage.
OEM-Behavior 1: Output voltage changed with external components.
Unlike the mp6-OEM, the frequency on the mp6-XOEM cannot be selected via external capacitor. This can only be
done my supplying a clock signal to the CLK-pin witch is shown in the next chapter.
Operation with variable settings via microcontroller
Using a microcontroller to operate the micropump, a square wave signal (0V-VDD; 50% duty-cycle) with four times
the desired output frequency has to be supplied to the CLK Pin.
The amplitude can be set with an analog voltage between 0 V and 1.25 V. Voltages above 1.25V up to VDD are
allowed and keep the output voltage at maximum.
For minimizing the power consumption, the mp6-XOEM can be switched off. To do this, apply a 0V signal to the
AMP-pin.

Rev. 1.2 (04.2020)
Schematic 4: Controlling settings via microcontroller
Operation with variable settings via I²C-Interface
The mp6-XOEM can also be operated using the I²C-Interface. Using this interface all the features of the chip can be
accessed. The functionality and procedures are identical to the mp6-QuadOEM. A complete interface and protocol
description can be found in the manual of the mp6-QuadOEM on our download page.
To activate the I²C-Interface the onboard processor has to be deactivated by tying the reset pin to Ground. Select a
desired slave-address connecting pins A0 and A1 to either VDD or GND and interface the chip through the I²C-pins
SDA and SCL. Both need an external pullup resistor (47K recommended) tied to VDD. (There are no pullup resistors
onboard the mp6-XOEM)
Schematic 5: Controlling settings via I²C
All values are approximate and no guarantee of specific technical properties.
Changes in the course of technical progress are possible without notice.
