1Introduction
Thank you for buying the analyzer from the product range of on-line water quality monitors.
The analyzer belongs to the most modern systems on the market and sets new standards:
Simple to operate
Quick commissioning via menu
Easy maintenance and cleaning
Intelligent measuring-chamber design
High measuring accuracy
Self-calibrating
The analyzer for the monitoring of water quality is part of a water preparation system. This
handbook is tailored for both the manufacturers and the operators of such equipment.
This handbook contains instructions for the use and operation of the analyzer. Please read
these instructions carefully before operating the unit.
We recommend that this handbook is kept near the unit for quick reference although we have
made every effort to make the unit, as far as possible, self-explanatory in its operation.
The unit should only be operated in harmony with the instructions in this handbook.
We will not accept any liability for damage caused by operator error or failure to follow the
instructions found in this handbook.
Some details and instructions in this handbook may vary slightly from the delivered unit. We
reserve the right to make technical changes to improve our products without prior notice.
The analyzer from the product range is an on-line analyzer that automatically recognises and
warns of the increase in water hardness in a water preparation system. When used with a
water grading system, the professional monitors can control the minimum and the maximum
hardness (for drinking water for example).
This is not a system to prevent increase in water hardness.

2Unit description
The on-line hardness monitor analyzer is a compact analysis unit which is able to monitor the
presents of various chemicals in water. In these instructions, only the on-line monitoring of
total hardness and carbonate hardness are described.
2.1 Principle of Function
The 6051 is an on-line analyzer for the automatic investigation of water parameters by the
colorimetric test method. Following the introduction of a reagent into the water sample, a
colour reaction occurs. Depending on the chosen method, the unit either evaluates the
intensity of the colour or ascertains the value at which the colour changes. From this
information the analyzer calculates the concentration of the chemical content. The unit can
only ascertain one parameter. The method and the measurement range are determined by the
reagent.
2.2 Unit overview
The analyzer has two variations:
1. Analysis unit on wall mounting
The Analysis unit consists of a control unit and a measuring chamber. Both are
mounted on a wall mounting plate. This variation is completely functional and includes
the connections for the water inlets and outlets as well as the holder for the reagent
bottle. (Fig. 1)
2. Analysis unit in protective case
In addition an optional plastic case is available to protect the unit in environments
where extreme levels of dirt and grease are expected. (Fig. 2)The Analysis unit on the
wall mounting plate is easily fixed in the protective case by 4 screws. If the analysis unit
and the protective case are ordered together, they will be delivered assembled.
The analysis unit is operated by means of a menu, a graphic display and 6 keys on the control
panel.

Unit description
2.5 BOB-Operation
The abbreviation BOB stands for “Betrieb ohne Beobachtung“(which means “Operation
without Observation“). This a special term found in the German ‘TÜV’ rules for boiler-houses.
These rules require that an analysis unit has enough reagent to last for 72 hours for unmanned
operation.
A relay output can be used, for example to activate an alarm if the reagent level is below that
necessary for the minimum time interval.
The analysis unit is specially designed for ‚BOB‘-operation. Boiler systems require an accurate
monitoring of water quality, especially the hardness of the boiler supply water according to the
technical guide-lines for boiler systems TRD 604 (Technische Regeln für Dampfkessel, published
by the‘ TÜV’).
The analysis unit calculates the consumption of reagent to make sure that enough reagent is
available for reliable measurements during the period of unobserved operation.
If the next 72 hour ‘BOB’-operation cannot be reliably guaranteed, the alarm “Reagent
shortage” will be activated. Please check to see that the reagent is within its best before date.
Only use fresh reagent.
2.6 Installation requirements
Reagents / Maintenance sets / Accessories
There are various analyzer reagents available that cover a wide range of measurement. When
choosing the correct reagent, it is important that the hardness range to be monitored lies in
the middle of the measurement range of the reagent.
In all, the analyzer covers the measurement range of 3.6 - 5349 µmol/l. There are 11 reagents
available:

N.B. Indicators 530/500 and above are very temperature sensitive and it may be necessary to
correct the test results with reference to the environmental temperature.
The reagents are available in 500ml bottles. This amount is sufficient for about 10,000 analyses at low
hardness. The number of analyses is dependent upon the hardness level and the reagent used.
Reagents that are not in use should be stored in a cool dark place. Avoid direct sunlight. The
shelf life of the reagents is at least 24 months if stored below 25°C and in a dark place. High
temperature sand direct sunlight can significantly reduce the shelf life!

2.7 Maintenance sets
The analysis unit needs very little maintenance. There is a maintenance set available for the analysis
unit. It is recommended to change the dosing-pump cassette, the reagent pipes and the ‘o’-rings after
50,000 analyses or every 6 months.
It is also recommended that the measuring chamber is regularly cleaned –at least every 6 months. The
cleaning set is offered for this purpose. This set contains everything necessary in the way of equipment
including the cleaning fluid.

3General Safety
Please observe the following safety instructions before operating the unit.
We wish to inform you of the appropriate use, installation and maintenance of the analyzer in
order to ensure a safe, problem free operation. Please take careful note of the possible dangers
that may result from incorrect use. The safety symbols are explained and fundamental
instructions given. The reading of this chapter does not replace technical training. The
installation and the commissioning of this unit should only be carried out by an authorized
and qualified person.
This handbook describes the installation and the operation of the on-line analyzer for the
automatic ascertainment of water hardness.
This unit may only be used in accordance with the conditions described in this handbook. In
particular, the unit must be protected from wet and damp. The protection class of the unit on
an open mounting plate is IP43. When mounted in a protective case, the protection class is
IP54. Splashing or condensation should be avoided. The unit may only be used for the specified
purpose. During installation and operation of the analysis unit, the relevant regulations (e.g.
EN, DIN, VDE, UVV) should be observed.
The analysis unit should only be used to ascertain the total water hardness or the carbonate
hardness in the sample water. Correct operation can only be warranted if the manufacturers
recommended reagents and spare parts are used.
Changes to the electrical wiring and the programmes should only be carried out by a
designated and qualified person.
The connecting cables should be kept as short as possible and not laid next to, or in close
proximity to, power cables. Analysis may be adversely affected by strong electromagnetic
fields. In this case special protective measures should be applied. Correct earthing is essential.
It is recommended to have these operating instructions at hand during the initial operating of
the equipment in order to get an immediate understanding of the functions. Since the various
ideas build upon the previous information it makes sense to work through the chapters in their
printed order.
If any problems occur or questions arise during the operation of the analysis unit, you can get
assistance from your supplier. Try to locate the problem as accurately as possible or to record
the action and conditions that lead to the problem. This makes speedy assistance possible.
