1Introduction
Dear customer,
Congratulations on the purchase of your Dosing system. We are confident that it will meet
all of your requirements. We wish you trouble-free and successful operation.
The Dosing system eco-CONTROL EC200 DUOMIX consists of the dosing control unit
and the 2-component dispenser.
The dosing control unit has been developed and tested for high-precision work with our
2-component dispensers. The Dosing system has a wide variety of setting options for the
dosing quantity and dosing time. All the values that are related to production can be saved
and changed at any time. Operation is done via an intuitive operator guidance system
using a graphic user interface.
The 2-component dispensers have been developed and tested for high-precision work
with products ranging from low to high viscosity with extremely high repeat accuracy.
They are rotating displacement systems consisting of a rotor and stator and can be
dismantled in no time. A number of voids are produced as a result of the various
geometries of the conveying elements. Feeding that is either proportional to the angle of
rotation or else is rpm-dependent is produced by the rotation of the rotor in the stator.
Since the direction of flow is reversible, the material can be sucked back to allow a clean
thread break. Self-sealing depends on the viscosity.
We would appreciate your assistance in our efforts to maintain the highest possible
quality standards. We would be happy to consider any suggestions you may have on how
we might improve our products.

5.8 The dosing programs and their areas of application
General
In order to achieve the most accurate results with the eco-CONTROL EC200 DUOMIX,
all the main factors for a reproducible dosing process can be set.
The dosing system must be recalibrated each time the material is changed.
See 5.9, Calibration, page 19.
All the parameters of a dosing program can be saved. When using a memory card,
24 program slots are available for permanent storage.
Without the memory card, the data is stored temporarily on program slot 00. It is kept until
the dosing system is switched off.
The following values
can be defined,
depending on the
dosing program used:

5.8.1 Dosing programs
Quantity program
The Quantity program is used to give out a fixed and defined quantity of material.
Depending on the 2-component dispenser and the material used, it is possible to set very
small amounts per dosing. The dosing time is determined by the volume flow. The dosing
process can be broken off at any time before the set time has expired (“STOP” key).
Start / Stop program
The Start / Stop program is used if the 2-component dispenser is to feed the material over
an individual period controlled by the operator (or external control). The output quantity
can be defined. The dosing quantity is determined by the volume flow.
Time program
The Time program is used if the dosing is to run for a set period. This is triggered by the
operator (or an external controller). The output quantity can be defined. The dosing
process can be broken off at any time before the set time has expired (“STOP” key).
The maximum dosing time that can be set is 99.99 seconds.
5.8.2 Operating modes
Dosing manually
In the three dosing programs the dosing is initiated by pressing the “START” key.
The Quantity program and the Time program end the dosing time by themselves either
once the set values have been reached or at the end of the set dosing time.
In the Start / Stop program, dosing can be ended by pressing the “STOP” key.
Dosing with the foot switch
The dosing system reacts to the foot switch being activated as follows:
In the Quantity and Time programs the dosing can be stopped by pressing the
“STOP” key before the specified values have been reached (EMERGENCY STOP).
A set pause or a suck-back will be carried out, however.
