End-of-life disposal
The transmitters contain a small lithium battery that must be
disposed of responsibly in accordance with local environmental
regulations. The remainder of the equipment does not contain
any substance that causes undue harm to the environment and
must be disposed of in accordance with the Directive on Waste
Electrical and Electronic Equipment (WEEE). It must not be
disposed of in Municipal Waste Collection.
Service and spares
Only personnel from ABB or its approved representative(s) is
(are) authorized to attempt repairs to the system and only
components formally approved by the manufacturer should be
used. Any attempt at repairing the instrument in contravention
of these principles could cause damage to the instrument and
corporal injury to the person carrying out the repair. It renders
the warranty null and void and could compromise the correct
working of the instrument and the electrical integrity or the CE
compliance of the instrument. If you have any problems with
installation, starting, or using the instrument please contact
the company that sold it to you. If this is not possible, or if the
results of this approach are not satisfactory, please contact the
manufacturer's Customer Service.

System overview
These Operating instructions provide the following
information:
• schematics showing test gas requirements
• electrical connection details between the AZ10 probe
and AZ10 transmitter (and AutoCal option)
WARNING
• System configuration must be performed only by users or
personnel with approved access rights (user privileges).
• Read all relevant sections of this guide before configuring
the system or modifying system parameters.
• Install and use this equipment as detailed in this guide.
Install and use associated equipment in accordance with
the relevant national and local standards.
The AZ10 oxygen probe measures oxygen concentration in
process gas using an in situ 'wet analysis' method. The 'wet
analysis' method avoids measurement error (typically 20 % of
reading higher than the actual value) that is introduced by a
sampling system using the 'dry analysis' method.
System equipment comprises a (process-mounted) AZ10 probe
controlled by the transmitter. During operation, a zirconia cell
within the probe is held at a constant temperature of 700 °C
(1292 °F) by a probe heater and control thermocouple assembly.
If the heater control circuitry or software fails (unsafe), the
probe heater power supply is switched off, ensuring the system
fails 'safe' and protecting the heater from an over-temperature
failure.
An output generated at the zirconia cell is processed in
the transmitter giving a locally displayed O2 reading and a
4 to 20 mA retransmission signal (over any range between
0 and 25% O2).
