• The operation manual for this product
• Generally applicable and local accident prevention and environmental protection
regulations
• Safety data sheets for the conveyed materials, as well as for any cleaning products or
lubricants being used
2.5 Preventing damage to equipment
In order to prevent damage to equipment and to ensure precision dosing, ensure that
• the connecting cable for a dispenser may only be connected or disconnected when
the power supply is switched off. Otherwise, the electronics in the drive motor could
be damaged
• only original dosing pressure sensors adapted for the dosing control unit are to be used
• the dispenser must never be operated without material (the stator will be destroyed)
• the material inlet (feed) and the material outlet must never be closed during operation
• the material outlet (e.g. dosing needle or mixer) must not be damaged or blocked
• the dispenser is regularly checked and cleaned
• the specifications in the product data sheet for the material are observed and adhered to

PRODUCT DESCRIPTION
3Product description
The dosing control unit has been developed and tested for high-precision work with
1-component and 2-component dispensers. Simultaneous operation of two identical
1-component dispensers is possible. For 2-component dispensers, a dynamic mixer can
also be connected.
The dosing system has a wide variety of setting options for the dosing quantity and time.
All the values that are related to production can be saved and changed at any time.
Up to 100 different programs can be stored in the dosing control unit.
Operation is done via an intuitive operator guidance system using a graphic user interface.
Depending on the customer order, the required software licence will come pre-installed on
the dosing control unit. The corresponding software licence is also saved as a “backup” on
the supplied USB stick.
Converting to a different software licence can be done at any time without significant setup
times. Simply install the new chargeable software licence on the dosing control unit using a
USB stick (activation). Different software licences are available (see page 110). You can get
the new USB stick from your contract partner or by contacting the manufacturer, citing the
serial number.
New software licences are encrypted and can therefore only be installed on one dosing
control unit. The serial number (SN) of the associated dosing control unit is therefore printed
on the USB stick. The serial number (SN) of the dosing control unit can be found on the type
plate (see page 99).
The dispensers have been developed and tested for precision dosing of materials ranging
from low to high viscosity with extremely high repeat precision.
Preeflow dispensers are positive displacement pumps. The conveying elements comprise a
rotating part, the rotor, and a stationary part, the stator. The rotor, which is in the form of a
type of knuckle thread, rotates inside the stator, which has one more thread turn and twice
the pitch length of the rotor. As a result, conveying areas are produced between the stator
and the rotor rotating inside the stator. The rotor also moves radially within the stator.
The conveying areas move forwards continuously due to the movement. The flexible shaft
used to drive the rotor compensates for the eccentric movement of the rotor and is completely
maintenance-free.
Since the direction of flow is reversible, the material can be sucked back to allow a clean
thread breakage.
The dispenser can be dismantled very quickly.
