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.

1.4 Return

If the sensor has to be repaired, please return it cleaned to the sales centre responsible.

Please use the original packaging, if possible.

Please enclose the completed "Declaration of Hazardous Material and De-Contamination" (copy

the second last page of these Operating Instructions) with the packaging and the transportation

documents.

No repair without completed declaration!

1.5 Notes on safety icons and symbols

Warning!

This symbol alerts you to hazards. They can cause serious damage to the instrument or to

persons if ignored.

Caution!

This symbol alerts you to possible faults which could arise from incorrect operation. They could

cause damage to the instrument if ignored.

!Note!

This symbol indicates important items of information.

• Special measuring cable

• Immersion assembly

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.

3.3.3 Installing the sensor in immersion assembly CYA611

The immersion assembly CYA611-0B is designed for on-site installation of the sensor. Cover the

thread NPT 3/4" with a layer of Teflon tape. Screw the sensor into the assembly.

Note the instructions and safety guidelines in the operating instructions of the immersion

assembly.

3.4 Post-installation check

• Check the membrane for leak tightness und replace it if necessary.

• Is the sensor installed in an assembly and is not suspended from the cable?
