1.2 Measuring principle
The OXITEC
®
5000 O
2
analyzer system consists of an InSitu probe which is installed in a duct to measure non-
combustible process gases and of an electronic unit for voltage and gas supply, as well as for signal processing.
The oxygen sensor is at the tip of the probe and is regulated to 800 °C and works on the zirconium oxide principle of
measurement. Here, a mV signal between the reference gas side of the sensor (inside, instrument air 20.95% O
2
)
and the measured gas side is measured, which depends logarithmically on the ratio of oxygen partial pressures on
both sides of the sensor.
The mV signal is converted according to the Nernst equation into oxygen partial pressure within the process gas,
whereby the O
2
concentration is determined in the process gas. Gas-tight separation of reference air and process
gas is of particular importance.
Should combustible components such as CO or H
2
be present in the sample gas, they will react with oxygen at the
sensor surface and can reduce the measured value.
1.3 Intended use
Info
The OXITEC
®
5000 analyzer measure in flue gases of combustion plants or in comparable inert gas
mixtures. If oxidizable gas components are contained in these processes, contact ENOTEC.
For reasons of safety and the possibility of accidents, unauthorized conversions and modifications of the
system are prohibited.
Warning
The system cannot be used to determine the oxygen concentration of combustible gases or in a location
where combustible gases are present as the measuring cell temperature of 800 °C could present an
explosion hazard!
Info
The minimum concentration of O
2
in flue gas should, under normal process conditions, not be less than
0.5 %. If the O
2
concentration is regularly below 0.5 %, we recommend the option of CSP (Cell Surface
Protection) to protect the O
2
sensor
.
Caution
Under no circumstance should the measuring probe be directly connected to the 230 VAC main power
supply,as this will immediately destroy the probe heater element!
1.4 Safety hazards
Warning hot surface
During operation, the temperature of the probe filter head and of other parts exposed to flue gas is 150 °C
– 800 °C (302 °F – 1472 °F). Direct contact with the hot parts when dismantling or maintenance will cause
severe burns! The probe may only be removed with heat-insulated gloves. Before removing the probe,
always switch off the supply voltage of the electronic system. After removal, store the probe in a safe,
protected place and wait until it has cooled down below 35 °C (95 °F).
1.5 Disruption of the process
The analyzer system has to be kept in operation also in the event of the process being disrupted or if the plant is
powered off temporarily (e.g. at night or during the weekend).
Frequently cooling down and heating up of the probe results in thermal stress of the hot probe parts (heater,
thermocouple and sensor) and reduces their product life. ENOTEC will not accept any responsibility for resultant
damage.
1.6 Storage instructions
ENOTEC equipment and spares are to be stored in a dry and ventilated environment at temperatures between
-40 °C to +80 °C (-40 °F to 176 °F). Paint fumes, silicone sprays, etc. must be avoided in the storage environment.

2.7 Installation of the probe
Warning
When installing the probe, note the following:
- When the process is in operation, the probe should always be in operation (heated state). A cold
measuring probe during operation can lead to deposits and a shortening of the lifetime of the measuring
probe.
- If maintenance work takes place on the process gas side (e.g. drying heat resistance material, cleaning
with water, removal of old refractory lining, welding, chemical cleaning ...), mechanical and chemical
damage of the measuring probe and the measuring cell can occur.
In such cases, the probe should always be removed from the process.
The flue gas temperature, pressure and all other process conditions must be in accordance with the specification.
Leave enough space for insertion/removal of the probe and protection tube (if supplied) and ensure access to the
measuring probe and/or connecting box. Before cutting a hole in the flue gas duct, make sure that the inside of the
duct has enough space for probe installation and that no soot is blown out nearby or any obstacles are in the way.
For probe lengths exceeding 2000 mm, a support must be mounted inside the duct (every 2 m) to prevent the probe
and mounting tube from flexing or bending. ENOTEC recommends installing the probe horizontally (- 1 ° to - 3 °)
for the fastest possible response time. A vertical (90 °) installation decreases the response time significant.
The ambient temperature at the connection box and
the process temperature must not be exceeded.
Avoid vibrations greater 2g
Maintain the protection class Heavy equipment, ensure proper lifting and carrying

2.10 Adjusting the V-shield
Before installing the probe, the direction of flue gas flow must be determined and the filter head assembly turned
to such a position that the V-shield faces the oncoming flue gas. The filter head can be turned freely a full 360° for
this purpose, by loosening the counter nut, loosening the torx screw and rotating the filter head / V-shield to the
required position, and then tightening the torx screw and counter nut.

3 Initial Operation
3.1 Checklist before commissioning the system
Is the system number of the probe identical to the system number of the electronic unit? If not, change the
assignment.
Does the voltage specified on the name plate correspond to the line voltage? (See section 1.7 - Name Plates)
If not, contact ENOTEC.
Is the electrical wiring connected correctly? (See section 2.6 - OXITEC 5000 Wiring Diagram)
Are the pneumatic connections correct and gas tight? (See sections 2.15 and 2.16 - Pneumatic Connections)
Make sure that there are no leakages at the probe - e.g. is the counter flange welded gas tight to the duct and
are the flange bolts tightened sufficiently? Are gaskets in use? (See section 0 - Mounting of the Probe)
Do the conditions at site match the specification in the data sheets? (See section A - Technical Data)
3.2 System power up
Switch on the line voltage to the system. After a short power up information, the user is prompted to
Select language, set the System date, System time, enter a TAG number and ENOTEC REMOTE code (only if
