1 Introduction

The mp6-QuadEVA is an evaluation board that allows to control up to four mp6 micropumps

simultaneously with one setting and up to a frequency of 800 Hz.

It is possible to change pump voltage and pump frequency directly with the rotary control elements at the

board or via USB. Simple control software is provided with the board. Also any terminal software can be

used to remotely control frequency and amplitude or enable/disable each of the four pumps.

2 Proper use

2.1 Intended purpose

The mp6-QuadEVA was designed to control up to four micropumps for gas pumping, i.e. four pieces of

mp6-AIR micropumps.

Nevertheless it is also possible to pump liquids, either with the mp6-AIR, mp6-pp or the standard mp6

pump; though the higher frequencies will not result in a performance boost.

If liquids should be pumped, please regard the following:

The micropump is intended for pumping liquids or gases with varying flow rates controlled by the

electronics. The mp6-QuadEVA controller is intended as a pump driver for mp6-AIR/mp6/mp6-pp.

Any other use of the micropump or controller unit is deemed improper.

Do not make any modifications or extensions to the pump or controller without the prior written consent of

the manufacturer. Such modifications may impair the safety of the unit and are prohibited! Bartels

Mikrotechnik GmbH rejects any responsibility for damage to the unit caused by unauthorized modifications

to the pump and risk and liability are automatically transferred to the operator.

2.2 Misuse

The use of gases or liquids which may alone or in combination create explosive or otherwise health-

endangering conditions (including vapors) is not permitted.

2.3 Staff selection and qualification

All work in connection with the installation, assembly, commissioning/decommissioning, disassembly,

operation, servicing, cleaning and repairing of the pump and the controller must be carried out by qualified,

Tel: [phone], Fax: [phone]

suitably trained and instructed personnel. Work on electrical components and assemblies must be carried

out by personnel with the necessary qualifications and skills.

2.4 Safety notice

The mp6-QuadEVA generates voltages of up to 260 Vpp. All parts of the evaluation board can carry

voltages in this range. Therefore, the board should only be used by qualified personnel. Although the output

power of the module is very low, proper insulation according to the application conditions needs to be

considered by the customer. This especially applies to the bottom side of the PCB. Contact with water or

other liquids needs to be prevented. The pump must not be unplugged while the board is active.

DANGER

THE EVALUATION BOARD CAN CARRY HIGH VOLTAGE!

BE CAREFUL, WHILE CONNECTING AND HANDLING THE BOARD!

4 Interface and mode of operation

The board does not have any main switch. When connecting the power supply to the DC connector (5) the

board is ready for operation. Connecting to a PC is optional. The board can be operated without PC

connection. However, if connected to an USB-power supply or an USB-port the power connection via DC

connector is still necessary.

4.1 Push-button

The four push–buttons (9) allow turning the individual pumps on or off. If turned on the corresponding

LED (6) will be illuminated.

4.2 Rotary knob: pump voltage

Through rotation of the rotary knob “SW1” (7) the pump voltage of all pumps can be changed, please use a

small flat blade screwdriver. The following table lists which voltage corresponds to the positions:

position SW1

pump voltage

Figure 2 Pump voltage at rotary knob SW1

(with four connected pumps and a frequency of 100 Hz)

The pump voltage may vary due to the number of connected pumps. With more pumps to operate the load

increases, hence the max voltage decreases. The pump voltage can also decrease a bit when operating with

higher frequencies.

The control signal to the pumps is a pure sine signal. Therefore it is not the same as with the mp6-OEM.

4.4 Operation via USB port (after installation of the drivers)

The driving parameters can be set via your PC. For this purpose any terminal software can be used that is

capable of sending commands to serial COM-Ports. In the example below the Windows software

HyperTerminal is used. As the HyperTerminal is not available in Windows 7 anymore, we recommend

freeware terminal software like PuTTY (http://www.putty.org).

On the driver CD supplied in the set you will find simple control software that can be used for evaluation

(see chapter 4.7).

HyperTerminal example:

Step 1: Connect the power supply to the board.
Step 2: Connect the board to your computer.
Step 3: Start Windows HyperTerminal. Every new session has to be titled.
Step 4: Choose the COM-port specified in the device manager.
Step 5: The connection-settings have to be:

Bits per second: 9600; Data bits: 8; Parity: none; Stop bits: 1; Flow control: none

Figure 4 Commands via USB

As soon as the first command is transmitted via USB the evaluation board changes internally to USB driving

mode. In this mode of operation the red LED (3) is illuminated. Changes of pump voltage and frequency

overwrite the rotary knob settings. The appropriate driver for the board will be send via Email.

The mp6-QuadEVA can also be used via LabView, Matlab and the like. Using LabView, please ensure that

the “NI Serial” package is installed. This will be installed in regular cases together with LabView, but

sometimes this option is skipped during install.

It can be downloaded on the National Instruments website as the “NI-Serial” package:

http://joule.ni.com/nidu/cds/view/p/id/2316/lang/en

Afterwards it is possible to select the right COM-port in the VISA resource name.

4.5 Local control

The push-button (2) switches back to local control when the device is driven in USB driving mode. Pump

voltage and frequency will be reset to the rotary knob positions. The red LED (3) turns off.

5 Maintenance

5.1 Cooling

The board may create some heat at the control chip when under continuous operation and at max

performance. It was successfully tested for the duration of one hour at 800 Hz, 250 V and four connected

pumps; no active cooling was applied.

However, it is recommended to take care of sufficient air flow to remove excess heat or consider installing

some active cooling on the board.

5.2 Exchanging the micropump

To connect the mp6/mp6-AIR/mp6-pp and Molex, refer to following three figures. Orientate both

components as indicated on the first picture, the mp6/mp6-pp facing downwards with its serial number

marking (!) and the Molex connector with the four small openings visible from above. Then insert the

mp6/mp6-pp flex into the Molex connector (Step1). Close the Molex connector to complete the

interconnection between both components (Step 2).
