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.

4Safety
4.1 Informal safety measures
- The operation and maintenance manual must be kept together with the instructions of
the 2-component dispenser in the place where the dosing system is used at all times.
- General and local regulations on accident prevention and environmental protection
must also be provided and complied with.
4.2 Legend
The following symbols are used in this manual:
4.3 Intended use, warranty
The Dosing system is designed for controlling our 2-component dispensers in non
explosion-protected environments.
The warranty may be voided by any
- modifications and additions,
- use of non-genuine spare parts,
- repairs carried out by companies or persons that have not been authorized by
the manufacturer,
- use without original sensors for monitoring dosing pressure,
that are undertaken without the explicit and written approval of the manufacturer.
The manufacturer shall have no liability whatsoever for damage resulting from failure to
follow the Operation and maintenance manual.
The chemical resistance of the parts which are in contact with the material (see the
commissioning and maintenance manual of the 2-component dispenser) must be
ensured prior to commissioning.

4.4 Qualification requirements of operators and maintenance staff
The operating organisation is responsible for ensuring that operators and maintenance
staff are appropriately qualified. The Operation and maintenance manual 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 chemical
substances.
It is essential to comply with all of the safety instructions contained in the respective
Operation and maintenance manual for the 2-component dispenser that is connected to
the dosing control unit.
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 damage to equipment
Only remove and insert the mains plug of a 2-component dispenser (plug 16,
section 5.2, Connections on page 12) once the power has been switched off.
The electronics in the drive motor could be damaged if this precaution is not
taken.
Only use the original enclosed connection cables between the dispenser and
the dosing control. The connecting cables must not be extended or shortened.
This can lead to damage to the controller.
In addition to the standard length of 1.5 m, connection cable sets with 5 m (Art.no.
22266) and 10 m (Art.no. 22267) are also available.
The 2-component dispenser should only be operated with the original pressure
sensors connected, which have been adapted to the controller.
SAFETY

4.8 Potential hazards caused by the Dosing system
- Very high dosing pressures can be produced, depending on the viscosity and the speed
of rotation, and this could result in unintended spraying of the material. Adhere to the
correct delivery rate for the dosing needle used (needle cross-section).
- During initial commissioning and after being refilled, air bubbles in the material could
cause an uncontrollable spraying from the outlet nozzle. Only start production
operation once the Dosing system has been completely bled.
- Wear suitable protective clothing if using chemical or corrosive products, or products
that are hazardous to health. The safety regulations and manufacturer's
instructions must be observed and followed. Ensure adequate ventilation or
extraction. Take special safety precautions if working with dangerous material;
for example, provide eye flushing facilities if working with corrosive chemicals.
Failure to follow the instructions set out below can result in damage to the unit and
severe injury to persons in the vicinity.
