Instructions for appropriate handling

Instructions for appropriate handling – FLUIDIC
The micropump may only be rinsed or filled at theoutlet (only suctioning), otherwise the maximum
pressure of 1bar is exceeded. This will lead to a
malfunction of the pump.

Foreign material (e.g. fluff) in the fluid channel
affects the operating mode of the micropump. Pay
attention to a clean handling of the micropump.
Otherwise, this will lead to a malfunction of thepump. We recommend the use of filters.

Only pump liquids with a particle size <50 μm.
Otherwise, this will affect the performance of themicropump. We recommend the use of filters.
Please note that we offer suitable filters for yourapplication. Please contact.

Not every medium can be pumped with themicropumps and the filters used. Refer to thedatasheets which provide information about thechemical resistance of the micropumps and filters.

Instructions for appropriate handling

Instructions for appropriate handling - ELECTRICALA reliable connection between micropump and board
connector (for example: mp6-mol) must be ensured.
Otherwise, this will lead to a malfunction of the pumpor the electronics.

Do not interrupt the connection between the drivercontrol and micropump during operation. Otherwise,
this will lead to a malfunction of the pump or theelectronics.

The three figures on the right illustrate how toconnect the micropump to the plug. The pump cablehas to be inserted with the contact surfaces orientateddown into the plug. Both components are firmly
connected by closing the white plug. Whendisconnecting the pump, the board connector mustfirst be opened! Verify yourself that the board
connector is always locked before start running thepump. Otherwise, this will lead to a malfunction of thepump or the electronics.

The driver chips are very sensitive to electrostatic
discharge. This can occur if the driver chip isconnected to the supply voltage but the ground is notearthed. Touching any ground point on the mpMultiboard causes a discharge and leads to a defect.
The same effect occurs when using a grounded meter,
e.g. an oscilloscope, and taking measurements on thecontrol. With each contact to the measuring tips adischarge current flows that is dissipated via earth. To
prevent this, the earth terminal of the measuring
device should be connected to the ground of thecontroller before the measurement. Otherwise, this willlead to a malfunction of the electronics.

Instructions for appropriate handling - ELECTRICAL

Attention: The controls (mp-Lowdriver, mpHighdriver, mp-Highdriver4, mp-Multiboard, mpvalvedriver) are at high voltages. Touching thecontrols during operation is strictly prohibited.

Danger to life!

Before the first operation it is essential to take careto avoid reverse polarity and to stick to theoperating parameters in accordance with theoperating instructions. Otherwise, this will lead to themalfunction of the electronics.
Our controls are packaged in ESD material upondelivery. Please also take care for a suitable electronic
packaging after receipt of the goods and duringstorage. Minimal electrostatic discharges can cause
defects.

When controlling the micropumps, square-edged
rectangular signals should only be used for a shorttime, as otherwise the piezoactuators will be subjected
to heavy mechanical loads. This will lead to themalfunction of the pump.

Instructions for appropriate handling

Instructions for appropriate handling – MECHANICAL
Please do not bend the flex cable. The flex cable ofthe micropump must not be led around sharp corners
or edges or around the top or bottom of the pump.
Otherwise, this will lead to the failure of the pump or
the electronics.
The flex cable of the micropump is very sensitive andshould therefore be protected against possible
vibrations or tractive forces. We recommend a fixingof the micropump and the plug connection for traction
relief of the flex cable.

Do not modify the flex cable or similar.
Modifications may affect functionality and may nolonger ensure the warranty.

Take care that the flex cable of the micropump andalso the connector has no contact with any liquid ormoisture. Otherwise, this will lead to a short circuitand thus to the malfunction of the pump or theelectronics.

According to the manufacturer's specification theconnector is designed for only 30 cycles of operation.
A regular change is recommended.
