2 Design and Function
2.1 Dosing head
Liquid dosing head
This is the standard head for liquid dosing. It is used together
with pump module and bottle.
Manual dosing head
The manual dosing head is used for manual powder dosing. It
is equipped with a integrated RFID tag to store substance data
and to provide printing data.
Functional description
As soon as a head is inserted, the instrument automatically reads the data of the head. In addition,
the instrument performs automatic adjustments concerning the Dosing steps, automatic door
operation and other instrument settings.
When no dosing head is installed the instrument will replace head-specific information with factory
settings.
8 Quantos Automated Dosing
2.2 Data stored in the dosing head’s RFID
Every dosing head is equipped with a integrated RFID tag (1)
which stores and exchanges data with the instrument.
The following data is stored in the RFID tag of the head:
•User data
•This block holds information about the substance such as
the name of the substance, the filling and expiry dates, the
quantity, etc. This data can be edited by the user at any time
and should be entered before using a new head for the first
time to have the data available for reports and labels.

3.4.1 Connecting the tubes
Connectors of pump module
To Bottle PumpExhaustInlet
CAN CANRS232CPower Supply
The thinner tube is used for transporting liquid from the bottle to the liquid dosing head. The slightly
bigger tube is used for pumping air into the bottle. By adding air, pressure rises in the bottle. When
pressure reaches min. 0.3 to max 0.5 bar (4.4 to 7.2 psi) the micro dispensing valve in the dosing
head opens and liquid can ascend the liquid tube. The two tubes are further referred to as liquid tube
and air tube.
§The liquid dosing head is inserted in the liquid dosing head
support.
− Connect liquid tube (1) at bottle (2) and at liquid dosing
head (3).

NOTICE
Damage on tube connectors because of mishandling!
If the tubes are not removed correctly, the connectors and therefore the pump module
can be damaged.
Wrongly cut tubing can cause leaking connections.
1 To remove tubes, press down ring on connector and pull out tube carefully.
2 Cut tubes with a tube cutter.
A tube in the air inlet to bottle (5) opens the valve of the air outlet. Never leave a tube which is
connected to the air outlet unconnected at the other end because pressure can not be built up.
You can connect up to 3 bottles to the pump module (7).
