Safety instructions CCS120
1 Safety instructions
1.1 Designated use
The sensor is used for continuous measurement of total chlorine in water. Within this context
the following compounds are included in the term total chlorine:
• free chlorine (Cl2 (dissolved), HOCl, OCL-)
• bound chlorine (chloramines)
• organic-bound chlorine (e.g. cyanuric acid derivates)
Typical applications are:
• Controlling total chlorine content of drinking, industrial, process, cooling water and pool
sector
• Measuring total chlorine content in fresh water and sea water for process, swimming pool and
whirl pool treatment
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 organisation.

3.3.2 Installing the sensor in flow assembly CCA250
The flow assembly CCA250 is designed for on-site installation of the sensor. In addition to the
chlorine sensor, a pH and redox sensor can be installed. A needle valve regulates the flow within
the range of 30 ... 100 l/h (7.92 ... 26.40 US.gal/h). If the value drops below 30 l/h (7.92
US.gal/h) or flow stops completely, this can be detected by an inductive proximity switch and
an alarm signal plus locking of the dosage pumps can be triggered.
Note the instructions and safety guidelines in the operating instructions of the flow assembly.
If the medium is fed back into a surge tank, pipeline or the like, ensure that the thus generated
back pressure on the sensor does not exceed 1 bar (14.5 psi) and remains constant.
Negative pressure at the sensor, e.g. by feedback of medium to the suction side of a pump, must
be avoided.
