General notes

This operating manual describes the installation and operation of the online Analyzer SYCON 2702.

The installation and commissioning are to be carried out by an authorised specialist.

The device may only be operated under the conditions described in this operating manual. The

device may be used only for the specified purpose of use. For the installation and operation of the

Analyzer, all the provisions applicable on site (such as EN, DIN, VDE, UVV) are to be followed.

The Analyzer is used for automatic determination of total water hardness or carbonate water

hardness in process water. Proper operation can only be guaranteed if the reagents and spare parts

recommended by us are used.

Modifications to the electrical wiring and the programming may only be made by a trained

specialist.

The water connection pipes to the device should be kept as short as possible and should not be

laid together with network lines or in their immediate vicinity. In the vicinity of strong

electromagnetic emitters, the analysis can become disturbed. In this case, separate interference

suppression measures are to be taken; in particular the EMC directives are to be followed.

It is recommended to always have access to the analyzer when familiarising oneself with these

operating instructions in order to understand the described relationships and functions

immediately. Since certain areas are built upon one another, it is advisable to work through the

chapter in the specified order.

If there are any questions when using the analyzer, you will receive support from our partners or us.

You can reach us by phone during normal business hours or by email. You will find complete

contact details of our technicians and our partners on our website.

This operating manual contain various safety instructions that indicate possible risks when using

the analyzer. This specifically concerns hazards for

•people,

•this product or related devices and installations,

•the working environment.

Various symbols in this manual indicate special hazards in order to avoid personal injury and

equipment damage. Please read the entire text in full before starting work.

This symbol indicates useful tips for a better understanding of the device.

This symbol is a general warning that indicates circumstances that need to be

considered.

Pressure

This symbol is a warning that you must expect lines under pressure.

Voltage

This symbol indicates the risk of electric current and the endangerment of

people and electronic components and assemblies.

Transport

Check immediately after receipt that the device is complete and free from

transport damage. The analyzer is shipped in a manner safe for transport.

Nevertheless, damage may occur during transport. Instruct the deliverer

immediately about damage during transport.

Protect the analyzer from possible damage during transport. If necessary,

remove any liquids still in it in advance. Remove the reagent bottle and close

it to prevent the reagent from leaking.

Storage

Store the analyzer in a dry place at temperatures between 0 - 45° C and

without direct sunlight.

Instruction on disposal

The device must not be disposed of as residual waste. Bring the device to a collection point. The

battery should be disposed of separately.

Alternatively, you can return the analyzer to your dealer or us for disposal.

Scope of supply

The SYCON 2702 is available in two versions:

1. Wall-mounted analyzer

The analyzer consists of a controller and the measuring chamber. Both are mounted on a

wall bracket. This version is fully functional and includes connections for the water inlet and

-outlet and a holder for holding an reagent bottle (Figure 1).

2. Analyzer in housing

Optionally for wall-mounted analyzer, a plastic housing is available in order to use the

analyzer in locations where more severe contamination is expected (Figure 2). The analyzer

on the wall mount can be quickly mounted in the housing with 4 screws. If the analyzer and

the housing are ordered together, the device is already mounted in the housing.

SYCON 2702 in detail

Device description

The analyzer consists of the following components: The controller with graphic display and control

panel is on the left side of the device. 4 cable bushings are provided on the lower controller

housing. The dosing pump is on the right side and the measuring chamber is below the dosing

pump.

The dosing pump is plugged onto the motor shaft of the motor and snaps into the receptacle. It

can be removed without tools. The measuring chamber is attached to 2 guide pins on the

controller housing. This can also be removed without tools and is undone with 2 captive locking

pins. Dosing plugs, actuator plugs, inlet- and outlet plugs are attached to the measuring chamber

in the same way and can be quickly undone.

The measuring chamber, which is always depressurised and always filled to prevent germs, is in the

middle. The actuator plug with a white high-power LED is in the middle of the measuring chamber.

The sensor system is located in the housing. The agitator (magnetic agitator), which is firmly

connected to the housing, is below the measuring chamber.

The water connections for hoses with an outer diameter of 6 mm are below the reagent bottle.

Inlet with sample water (left) and outlet (right). Both are firmly bolted to the wall bracket.

There is a solenoid valve in the supply line behind the reagent bottle.

SYCON 2702 in detail

Principle of function

The SYCON 2702 based on the SYCON series is an online analyzer for the automatic determination

of water parameters according to the colorimetric titration method. By adding an reagent to the

water sample, a colour reaction is produced. Depending on the reagent used, the device evaluates

the colour intensity. By changing the colour of the sample during the addition of the reagent, the

SYCON 2702 calculates the concentration of the substances in water. The device can only

determine one parameter at a time. Parameters and measuring range are determined by the

reagent used.

Note on oxidizing agents:

Oxidizing agents, e.g. calcium hypochlorite, chlorine, chlorine dioxide, sodium hypochlorite or

ozone beyond the limits permitted in "TrinkwV 2012" attack the dye contained in the reagent and

interfere with the measurement. An exact determination of the water hardness is no longer

guaranteed. An activated carbon filter upstream of the analyzer can remove these oxidants from

the sample water and thus allow the correct determination of the water hardness.

The capacity of an activated carbon filter consumes during operation. Therefore, the activated

carbon filter must be replaced at regular intervals. The effectiveness of the charcoal filter can be

checked using Caldur® test kits.

range of the total hardness is achieved by using different reagents. (The

following units are available for the analysis value: °dH, °f, ppm CaCO3,

mmol/l, °e, °Ж these are shown in the display).

Accuracy

Measuring accuracy: ± 5% of the maximum reading of the respectively used

reagent.

Repeat accuracy: ± 2.5% of the maximum reading of the reagent used

Please note: Depending on the substances in the water, there may be shifts

in the reading that affect the measurement accuracy. In such cases, we

recommend performing a hardness measurement by hand titration and

calibrating the analyzer to this reading.
