1 Safety instructions
1.1 Designated use
Sensor CSS70 and transmitter CSM750 form an analytical system for continuous measurement of
the spectral absorption coefficient.
The system is specifically designed to monitor the dissolved organic substances:
• in the wastewater effluent stream and
• in drinking water treatment plants.
Any other use than the one described here compromises the safety of persons and the entire
measuring system and is, therefore, not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.
1.2 Installation, commissioning and operation
Please note the following items:
• Installation, commissioning, operation and maintenance of the measuring system must only be
carried out by trained technical personnel.
The technical personnel must be authorized for the specified activities by the system operator.
• Electrical connection must only be carried out by a certified electrician.
• Technical personnel must have read and understood these Operating Instructions and must
adhere to them.
• Before commissioning the entire measuring point, check all the connections for
correctness. Ensure that electrical cables and hose connections are not damaged.
• Do not operate damaged products and secure them against unintentional
commissioning. Mark the damaged product as being defective.
• Measuring point faults may only be rectified by authorized and specially trained
personnel.
• If faults can not be rectified, the products must be taken out of service and secured against
unintentional commissioning.
• Repairs not described in these Operating Instructions may only be carried out at the
manufacturer’s or by the service organization.
1.3 Operational safety
The measuring system has been designed and tested to the highest standards and left the factory in
perfect functioning order.
Relevant regulations and European standards have been met.

3.4 Installation
• Select a measuring point where representative measurement can be taken. Do not mount the
sensor where medium flow is turbulent and fast-flowing.
• We recommend fitting the transmitter with a weather protection cover (see "Accessories").
• Attach the sensor to a special extension tube. Due to the weight of the sensor (approx. 5 kg), the
sensor cable does not provide sufficient support. Never carry the sensor by its cable.
• The best fixture is a pendulum frame which holds the sensor vibration-free.
• Install the system at an easily accessible position to prevent danger for the operating personnel
(during commissioning or when carrying out maintenance and cleaning work).
• Route all cable connections to prevent mechanical damage and interference from other lines.
• Install measuring channels of the sensor in the direction of flow to obtain a self-cleaning effect.
• The activated sludge version of the sensor is equipped with a cleaning unit which prevents soiling
or blocking due to particles by compressed air. For other applications with soiling contents, the
cleaning unit is available as an accessory. Install the air outflow of the cleaning unit at the narrow
side of the light slit.
3.5 Post-installation check
• After installation, check that all connections are fitted tightly and are leakage resistant.
• Check that the sensor is secured such that it is free of vibration and tension.
• Check whether all cables have been routed without damage or electromagnetic interference.

4.1 Electrical connection
#Warning!
• The electrical connection must only be carried out by a certified electrician.
• Technical personnel must have read and understood the instructions in this manual and must
adhere to them.
• Ensure that there is no voltage at the power cable before beginning the connection work.
4.2 Terminal assignment
#Warning!
• Ensure before connection that the power supply voltage corresponds with the voltage specified
on the nameplate!
• A clearly marked power supply disconnecting device must be installed in the vicinity of the
instrument.
• Protect the transmitter by a 1 A fuse.
• Only switch the transmitter on when the sensor connector is plugged in and secured.
• Only plug in or remove the sensor connector when the transmitter is switched off.
