Section 2 General information
2.1 Safety information
Read the entire operating instructions before the instrument is unpacked, set up or put into
operation. Observe all hazard and warning notes. Non-observance could lead to serious
injury of the operator or damage to the device.
To make sure that the protection provided by this instrument is not impaired, do not use or
install this instrument in any manner other than that specified in these operating
instructions.
2.1.1 Hazard information in these operating instructions
DANGER
Indicates a potentially or imminently hazardous situation that, if not avoided, can result in death or
serious injury.
WARNING
Indicates a potentially or imminently dangerous situation that, if it is not avoided, can lead to death
or to serious injuries.
Indicates a possible dangerous situation that can have minor or moderate injuries as the result.
Indicates a situation that, if it is not avoided, can lead to damage to the device. Information that
should be particularly emphasized.
Note: Information that supplements aspects of the main text.
2.1.2 Precautionary labels
Observe all labels and tags attached to the instrument. Non-observance may result in
personal injury or damage to the device. For symbols attached to the instrument,
corresponding warning notes are found in the user manual.
This symbol may be attached to the device and references the operation- and/or safety notes in the user manual.
Electrical devices marked with this symbol may no longer be disposed of in unsorted domestic or industrial waste in
Europe after August 12, 2005. According to valid provisions (EU Directive 2002/96/EC), consumers in the EU must
return old electrical devices to the manufacturer for disposal from this date. This is at no cost to the consumer.
Note: Contact the manufacturer or supplier for instructions on how to return end-of-life equipment,
manufacturer-supplied electrical accessories and all auxiliary items for recycling or proper disposal.

General information
2.2 General information about the probes
The probes have been developed for use in municipal waste water applications.
The ISE probes (refer to Figure 2) feature ion-selective electrodes for continuous
measurement of ammonium and/or nitrate in the tank itself. They operate without reagents
and require no further processing of the sample. The ammonium/nitrate ions are
measured using an ion-selective electrode.
The only wearing part is the sensor cartridge (refer to Figure 3, Page 9) (order number
LZY694). The sensor cartridge consists of the ion-selective electrodes for ammonium and
potassium (compensation electrode for ammonium) or nitrate and chloride (compensation
electrode for nitrate), a pHD reference system and a temperature sensor for comparing
temperatures.
Note: Note that the nitrate and chloride electrodes are deactivated when using the AISE sc probe.
When using the NISE sc probe, the ammonium and potassium electrodes are deactivated.
An additional cleaning unit designed for automatically cleaning the sensor cartridge
membranes can be ordered separately. For details, refer to the instruction sheet supplied
with the cleaning unit.
The manufacturer recommends to use the High Output Air Blast system for the
compressed air supply (refer to 7.2 Accessories, page 39); This is a compressor in
weather-proof plastic housing.

2.3 Functional principle
Ion-selective electrodes have a special membrane to which only a specific type of ion can
adhere. As a result, an ion-specific potential forms on the membrane surface. To measure
a potential difference, a reference system is required that will not be affected by the
sample to be measured.
The CARTRICALTM technology reduces cross-sensitivity by calibrating not only the
individual electrodes but also the measuring electrode against the compensation
electrode and the reference; this is carried out at the factory. The reference system is
designed using pH-differential technology and is therefore particularly stable in terms of
drift and contamination.

Section 3 Installation
Only qualified personnel should conduct the tasks described in this section of the operating
manual.
3.1 Unpack the probe
Remove the probe from the shipping container and inspect it for damage. Verify that all
items listed in Figure 4 are included. If any items are missing or damaged, contact the
manufacturer or your distributor.

NOTICE
Do not touch the membrane on the sensor cartridge to avoid damage of the sensor.
Make a note of the date on the sensor cartridge certificate. It is not an expiration date, but indicates
the optimum date to put the sensor cartridge into operation to ensure a maximum service life.
