1 Safety instructions

1.1 Designated use

The ion-selective electrode system is designed for measuring tasks in the activated sludge basin

of municipal sewage treatment plants.

The following parameters can be monitored depending on the device version:

•Nitrate

• Ammonium

• Potassium (to compensate ammonium)

• Chloride (to compensate nitrate)

• pH value

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 sensor has been designed and tested according to the state of the art and left the factory in

perfect functioning order.

Relevant regulations and European standards have been met.

As the user, you are responsible for complying with the following safety conditions:

• Installation instructions

• Local prevailing standards and regulations.

3.3 Installation instructions

"Caution!

• Select a measuring place that is easily accessible so that no hazards for operating staff can

occur.

• Select a measuring place with representative concentration levels.

• If mounting the transmitter outdoors, you must use a weather protection cover which you can

order as an accessory.

1. Secure the transmitter to an upright post, a railing or a wall.

2. Mount the sensor using the optional bracket. The sensor must be immersed in the medium

over approx. 30 cm (12").

3. Route the cables in such a way that no mechanical damage or interference influences can

arise from other cables.

4. Connect the compressed air to the sensor.
