1Introduction
Dear customer,
we congratulate you on buying your Dosing system. We are certain that it will fully meet
your requirements. We wish you trouble-free and successful operation.
The dosing system eco-CONTROL EC200-K is made up of the dosing control and the
2K dispensers.
The Dosing system has been designed and tested for the most precise work with our
dispensers. 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. Operation is done via an intuitive operator guidance system using a graphic
user interface. It is possible to operate two dispensers at the same time. It is possible to
set it up for other dispensers at any time without noteworthy setting-up times.
The dispensers have been developed and tested for high-precision work with products
ranging from low to high viscosity with extremely high repeat precision.
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. Turning the rotor in the stator creates conveyance
which is either proportional to the angle of rotation or rpm-dependent.
Since the direction of flow is reversible, the medium can be sucked back to allow a clean
break of the thread. Self-sealing depends on the viscosity.
We would be glad of your help as part of our efforts to maintain our standard of quality at
the highest possible level. Please tell us about any possible ways we can improve our
product.

4.8 Sources of danger due to Dosing system
- Very high dosing pressures can be produced, depending on the viscosity and the speed
of rotation, and this could result in unintended spurting out of the medium. Check the
flow quantity in relation to the dosing needle used (needle cross-section).
- When it is started up for the first time and after being refilled, air bubbles that are
included in the medium could cause an uncontrollable spurting out of the outlet nozzle.
Only start production operation once the Dosing system has been completely
bled.
- Wear suitable protective clothing if chemical, corrosive or dangerous products are
being used. Note and comply with the safety stipulations and the information from
the manufacturer. Ensure sufficient bleeding or extraction of air. Take special safety
precautions if working with dangerous media, for example, provide eye flushing
facilities if working with corrosive chemicals.
Failure to follow the instructions given below can result in damage to the unit and
possible severe injury to persons in the vicinity.

5.8 The dosing programs and their areas of application
General
In order to achieve teh moste accurate results with the eco-CONTROL EC200 DUO, all
the main factors for a reproducible dosing operation can be set.
The dosing system must be recalibrated each time the medium is changed.
See 5.9, Calibrating page 17.
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:
Dosing program
Flow quantity Flow rate Dosing time Sucked back quantity Suck back speed Pause before Sucking back Material density

5.8.1 Dosing programs
Quantity program
Quantity program is used to give out a fixed and defined quantity of medium. Depending
on the 2K-dispenser and the medium used, it is possible to set very small amouts per
dosing. The dosing time is determined by the volume flow. The dosing operation can be
broken off at any time until the set time has expired (STOP key).
Start / stop program
The Start / stop program is used if the 2K-dispenser is set to convey the medium 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 be done for a set period. This is triggered by
the operator (or an external controller). The output quantity can be defined. The dosing
operation can be broken off at any time until 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 by itself 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 and
a return flow are carried out as well.

Once the pot life has expired, dosing takes place (empty shot) in accordance with the
set mixer size, filling it with "fresh" medium.
Empty shot = single dosing
Continuous = ongoing in accordance with the pot life.
The Rinse function can be activated after a pot life has been entered.
The value must be smaller than the pot life. It starts running backwards after the
mixer has been filled (while the pot life is running). The remaining time is shown.
Once the flush time has expired, the mixer is rinsed once with the component from
the selected dispenser (A or B). This ensures that the mixer is filled with just one
medium and protected against sticking. The quantity corresponds to the set mixer
size.

5.10.4 Dosing quantity
General on determining the dosing amount.
Notice: If a value that differs from 100% is set in the Calibration manual menu
(section 5.9.2), this affects the results of the dosing.
The smallest dosing quantities can be determined most easily via the weight. We
recommend setting the material density first.
Dose your required quantity with the Start / stop program and weigh it. Now input in the
quantity program the quantity in g.
