Device description
The analyser consists of the following components: The control unit with graphic display and
control panel is located on the left side of the unit. There are 4 cable feed-throughs on the lower
control housing. On the right side is the dosing pump and below it the measuring chamber.
The dosing pump is attached to the motor shaft of the motor and engages in the receptacle. It can
be removed without tools. The measuring chamber is attached to 2 guide pins on the control
housing. It can also be removed without tools and is released with 2 captive locking pins. The
metering plugs, actuator plugs, inlet and outlet plugs are attached to the measuring chamber in the
same way and can be released quickly.
In the middle is the measuring chamber, which is basically pressureless and always filled to avoid
contamination. In the middle of the measuring chamber is the actuator plug with a white high-
power LED. The sensor system is located in the housing. Below the measuring chamber is an
agitator (magnetic stirrer) that is firmly connected to the housing.
Under the reagent bottle are the water connections for hoses with an outer diameter of 6 mm: inlet
with sample water (left) and outlet (right).
Both are firmly screwed to the wall bracket.
Behind the reagent bottle there is a solenoid valve in the supply line.

Operating principle
The SYCON P based on the SYCON series is an online analyser 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 generated. Depending on the reagent used, the device evaluates the
intensity of the colour. Through the colour change of the sample during the addition of the reagent,
the SYCON P calculates the concentration of the water ingredient. The device can only determine
one parameter at a time. Parameter and measuring range are determined by the reagent used.

Note on oxidising agents:
Oxidising agents such as calcium hypochlorite, chlorine, chlorine dioxide, sodium hypochlorite or
ozone above the limits permitted in "TrinkwV 2012" attack the dye contained in the reagent and
interfere with the measurement. This means that an exact determination of the measured value is
no longer guaranteed. An activated carbon filter connected upstream of the analyser can remove
these oxidants from the sample water and thus enable the correct determination of the measured
value.
The capacity of an activated carbon filter is consumed during operation. Therefore, the activated
carbon filter must be replaced at regular intervals. The effectiveness of the activated carbon filter
can be checked with the help of Caldur® test sets.

Installation
The installation should be done in the following steps to avoid errors:
•Install the analyser in a dry, easily accessible and easily visible place.
•Secure the analyser or the housing stably with screws according to the instructions.
•Connect the unit electrically and make sure that the input voltage is correct. Check the type
plate to make sure.
•Connect the inlet and outlet according to the installation instructions. Make sure that the
inlet pressure is correct and that the outlet is kept free and short.
•Insert the reagent and connect it to the dosing pump. Make sure that the connecting hoses
are not twisted.
•Do not switch on the unit until all preliminary work has been completed and the housing is
closed.
•Now make the unit settings on the unit.
The sample water must be clear and free of solids. Otherwise, a filter must be
provided upstream of the analyser. Solids in the water can damage the
solenoid valve or prevent it from closing. If the solenoid valve blocks or no
longer opens or closes, the flow through the measuring chamber will not be
correct. This leads to incorrect measurements.
The temperature of the sample water must be between 5 and 40 °C.
If the sample water has a higher temperature, a sample cooler must be used.
This is available as an accessory.
