General notes

These operating instructions describe the installation and operation of the online analyser SYCON

P. Installation and commissioning must only be carried out by an authorised specialist.

The unit may only be operated under the conditions described in these operating instructions. The

unit may only be used for the specified purpose. When installing and operating the analyser, all

locally applicable regulations (such as EN, DIN, VDE, UVV) must be observed.

The switch of the analyser does not disconnect the mains terminals from the power supply. The

installation of a suitable electrical disconnecting device is the responsibility of the system operator.

Before opening the housing, disconnect the unit from the power supply and secure it against

unintentional reconnection.

The analyser is used for the automatic determination of the p-value in the process water. Proper

operation can only be guaranteed if the reagents and spare parts recommended by us are used.

Changes to the electrical wiring and programming may only be carried out by a designated

specialist.

The water connection lines to the unit should be kept as short as possible and should not be laid

together with mains lines or in their immediate vicinity. In the vicinity of strong electromagnetic

radiators, interference with the analysis may occur; in this case, separate interference suppression

measures must be taken, in particular the EMC guidelines must be observed.

It is recommended to always have access to the analyser when familiarising oneself with the help of

these operating instructions in order to be able to understand the explained correlations and

functions immediately. Since certain areas build on each other, it makes sense to work through the

chapters in the given order.

If you have any questions about the use of the analyser, you will receive support from our partners

or from us. You can reach us by telephone during normal business hours or by email. The contact

details of our technicians and our partners can be found on our website.

Safety instructions and symbols used

In this operating manual you will find various safety instructions that point out possible risks when

handling the analyser. This concerns in detail dangers for

•People,

•this product or associated equipment and installations,

•the working environment.

Subject to change without notice Page 5

Various symbols in these operating instructions indicate special dangers to prevent personal injury

and damage to the appliance. Please read the entire text completely before starting work.

This symbol draws your attention to useful tips that contribute to a better

understanding of the unit.

This symbol is a general warning that indicates circumstances that must be

observed.

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

Voltage

This symbol indicates the danger of electric current and the danger to

persons and electronic components and assemblies.

Transport

Immediately after receipt, check that the unit is complete and has no

transport damage. The analyser is delivered in a transport-safe condition.

Nevertheless, damage may occur during transport. Immediately inform the

delivery person of any transport damage.

Protect the analyser from possible damage during transport. Remove any

liquids still in it beforehand. Remove the reagent bottle and close it to

prevent the reagent from leaking.

Storage

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

of direct sunlight.

Disposal note

The appliance must not be disposed of with residual waste. Take the unit to a collection point. The

battery must be disposed of separately.

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

SYCON P in detail

The SYCON P online analyser is characterised by the following features:

•Reliable, accurate and fully automatic analyser

•Monitoring of two programmable limit values

•Simple commissioning through configuration wizard

•Self-calibrating and self-monitoring

•Easy maintenance and cleaning

•Compact design

•Multicolour, multilingual graphic display

•Relay output for limit value 1

•Relay output for limit value 2 or reagent alarm

•Relay output for fault indication

•Relay output for feed pump, reagent alarm or cooling water valve

•Analogue output 0/4 - 20 mA for measured value or status message

•2 programmable digital inputs

•Measurement data memory and measurement data log on SD card

•No formation of condensate in the optics

•Software updates via SD card

Scope of delivery

The SYCON P is available in two versions:

1. Analyser on wall mount

The analyser consists of a control unit and the measuring chamber. Both are mounted on a

wall bracket. This version is completely functional and contains the connections for the

water inlet and outlet as well as a holder to accommodate an reagent bottle (Figure 1).

2. Analyser in housing

A plastic housing is available as an option for the analyser on the wall bracket in order to use

the analyser in places where more contamination is to be expected (Figure 2). The analyser

on wall bracket can be quickly mounted in the housing with 4 screws. If the analyser and

housing are ordered together, you will receive the analyser already mounted in the housing.

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.

A more detailed description of the components can be found from page 40.

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.
