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.

4Safety
4.1 Informal safety measures
- The operating and maintenance manual must be kept, together with the operating and
maintenance manual of the dispenser(s), at the site where the dosing system is used
at all times.
- General and local regulations on health, safety and environmental protection must also
be provided and complied with.
4.2 Use of symbols
The following symbols are used in these instructions:
4.3 Correct use, warranty
The Dosing system is designed for controlling our dispensers in non explosion-protected
environments.
Any
- modifications and additions,
- use of non-genuine spare parts,
- repairs by persons or organisations not authorised by the manufacturer
- use without original sensors for monitoring dosing pressure
that are done without the explicit and written approval of the manufacturer, can lead to
the warranty being rendered null and void.
The manufacturer shall have no liability whatsoever for damage resulting from failure to
follow the Operating and maintenance instructions.
The chemical resistance of the parts which come into contact with the product (see the
commissioning and maintenance manual of the dispenser) must be ensured prior to
commissioning.

4.4 Qualifications of the operators and maintenance personnel
The operating organisation is responsible for ensuring that the operators and
maintenance personnel are suitably qualified. The Operating and maintenance
instructions must have been read and understood. The relevant technical rules and safety
regulations must be complied with.
4.5 Organisational measures
The necessary personal protective equipment must be
provided by the operating organisation. All safety devices
that are fitted must be checked regularly. Safety glasses
and overalls must be worn during operation and cleaning
to provide protection against any splashes of chemicals.
All of the safety information contained in the respective
Operating and maintenance instructions for the dispenser(s) that are connected to the
Dosing system must be complied with.
4.6 Preparation for commissioning - visual inspection
The Dosing system must be visually examined each day before the start of work and
before all shift changes. If there is any doubt as to the system's readiness for operation,
it must be shut down immediately and inspected by a specialist before operation
resumes.
4.7 Preventing material damage to the motors of the 2K-dispenser
The 2K-dispenser lead (connector 16, Chapter 5.2, Connections, on page 11)
may only be connected and disconnected when the power supply is isolated.
The electronics in the drive motor could be damaged if this precaution is not
taken.
The 2K-dispenser should only be operated with the original pressure sensors
connected, which have been adapted to the controller.

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.
