Authorized use
DANGER!
Danger – high pressure!
▶ Before disconnecting any lines and valves, turn off the pressure
and vent the lines.
Risk of electric shock!
▶ Before reaching into the device or equipment, switch off the power
supply and secure to prevent reactivation!
▶ Observe applicable accident prevention and safety regulations
for electrical equipment!
CAUTION!
Risk of burns/risk of fire if used continuously through hot
device surface!
▶ Keep the device away from highly flammable substances and
media and do not touch with bare hands.
General hazardous situations.
To prevent injury, ensure the following:
▶ Ensure that the system cannot be activated unintentionally.
• Do not place a physical load on the housing (e.g. by placing objects
on it or standing on it).
• Do not make any external alterations to the housing of the device.
Do not paint housing parts or screws.
▶ Installation and repair work may be carried out by authorized
technicians only and with the appropriate tools.
▶ After an interruption in the electrical or pneumatic supply,
ensure that the process is restarted in a defined or controlled
manner.
▶ The device must only be operated when in a perfect condition
and in consideration of the operating instructions.
▶ The general rules of technology must be observed for applica-
tion planning and operation of the device.
NOTE!
Electrostatic sensitive components/modules!
• The device contains electronic components which react sensitively
to electrostatic discharge (ESD). Contact with electrostatically
charged persons or objects are hazardous to these components.
In the worst case scenario, they will be destroyed immediately or
will fail after start-up.
• Observe the requirements in accordance with DIN EN 61340-5-1/5-2
to minimize or avoid the possibility of damage caused by sudden
electrostatic discharge!
• Also, ensure that you do not touch electronic components when
the power supply voltage is present!

5 SYSTEM DESCRIPTION
Due to the high reproducibility, the unit, which operates according to
the diaphragm pump principle, is suitable for the precise dosing of
very small fluid quantities in the µl range.
The dosing unit can also be used for aggressive media as highquality materials are used for the parts that come in contact with the
media.
The structure of the unit with active inlet and discharge valves
enables a bidirectional supply. The electronic control systems are
integrated in the unit.
The supply rate of the dosing unit is dependent on the viscosity of
the supplied medium and the flow resistances up- and downstream
of the dosing unit (e.g. hose system).
5.1 Conformity
The micro dosing unit Type 7615 conforms to the EC directives
according to the EC Declaration of Conformity.

8.3 Dosing quantity
The dosing unit is set to a pumping volume of 5µl/pump stroke as
standard. This value cannot be changed.
8.4 Selecting the dosing mode
By default, the dosing unit is configured so that it doses at a frequency of 5 Hz once the power supply voltage is connected. The
dosing mode can be pre-selected on the rotary switch for the electronics once the cover has been removed (see “Fig. 6: Setting the
dosing mode”).
DANGER!
Risk of electric shock!
▶ Before reaching into the device or equipment, switch off the power
supply and secure to prevent reactivation!
▶ Only adequately trained personnel may reach into the device!

(standard)
5 5 Hz service mode;
unit stops after
100 cycles
Unit doses precisely 5 µl
(= 1 stroke) and then stops.
Power supply voltage must be at
least 120 ms for this purpose. If the
power supply is then interrupted
for > 2 ms and is subsequently
reconnected, a stroke is initiated, etc.
doses at the selected frequency
once the power supply voltage is
connected.
For servicing purposes: Following
connection of the power supply
voltage, the unit operates at a frequency of 5 Hz for precisely
100 pumping cycles and then
stops.
The supply rate can be checked
using this function.
