An exclusive User’s Manual might be attached to the products whose sufx codes or option
codes contain the code “Z” (made to customers' specications). Please read it along with this
manual.
The EXAxt ZR Separate type Explosion-proof Zirconia Oxygen Analyzer has been developed for
combustion control in various industrial processes. This analyzer basically consists of a detector
and a converter. You can select between several versions, based upon your application.
Optional accessories are also available to improve measurement accuracy and automate
calibration. An optimal control system can be realized by adding appropriate options.
This instruction manual refers to almost all of the equipment related to the EXAxt ZR.
You may skip any section(s) on the equipment which is not included in your system.
Regarding the HART communication protocol, refer to IM 11M12A01-51E.
IM 11M12A01-51E has been published as " Model EXAxt ZR Series HART Protocol" .
The all-in-one version (with sensor and analyzer integrated in one body) is described in
IM 11M12A01-04E
<Before using the equipment, please read any descriptions in this manual related to the
equipment and system that you have, on appropriate use and operation of the EXAxt ZR.>

n Precautions in Handling Explosion-proof Zirconia Oxygen Analyzer
The explosion-proof zirconia oxygen analyzer (Model ZR22S) are designed as explosion-proof
instruments.
When using either of these instruments in an explosion-susceptible hazardous area, note the
following and observe the given precautions:
Use only the supplied, the explosion-proof zirconia oxygen analyzer (Model ZR22S) and
accessories, or any explosion-proof certication may be invalidated.
For the details, refer to the system congurations in the manual.
CAUTION
Only trained persons use this instrument in industrial locations.

n For the safe use of this equipment
WARNING
EXAxtZR is very heavy. Handle it with care. Do not drop it. Handle safely to avoid injury.
Connect the power supply cord only after conrming that the supply voltage matches the rating of
this equipment. In addition, conrm that the power is switched off when connecting power supply.
Some process gas is dangerous to people. When removing this equipment from the process line
for maintenance or other reasons, protect yourself from potential poisoning by using a protective
mask or ventilating the area well.
CAUTION
Requirements for explosion-proof use:
The ZR22S is connected to a ZR402G or AV550G*
The ambient temperature is in the range -20 to +60°C. The surface temperature of the ZR22S is
not over the temperature class T2 (300°C)*
*1: Refer to IM 11M12D01-01E
*2: The terminal box temperature does not exceed 150ºC

.
Oxygen concentration of sample/reference /calibration gas shall not exceed that found in normal
air, typically 21 vol%.

that is mounted in a non-hazardous area.
IM 11M13A01-02E
NOTE
The cell (sensor) at the tip of the detector is made of ceramic (zirconia element). Do not drop
the detector or subject it to pressure stress.
• Do NOT allow the sensor (probe tip) to make contact with anything when installing the
detector.
• Avoid any water dropping directly on the probe (sensor) of the detector when installing it.
• Check the calibration gas piping before introducing the calibration gas to ensure that there
is no leakage of the gas. If there is any leakage of the gas, the moisture drawn from the
sample gas may damage the sensor.
• The detector (especially at the tip) becomes very hot. Be sure to handle it with gloves.

1. Overview
The EXAxtZR Separate type Explosion-proof Zirconia Oxygen Analyzer is used to monitor
and control the oxygen concentration in combustion gases, in boilers and industrial furnaces,
for wide application in industries which consume considerable energy–such as steel, electric
power, oil and petrochemical, ceramics, paper and pulp, food, or textiles, as well as incinerators
and medium/small boilers. It can help conserve energy in these industries. The EXAxtZR also
contributes to preservation of the earth’s environment in preventing global warming and air
pollution by controlling complete combustion to reduce CO
ZR22S Separate type Explosion-proof Detector uses a high-reliability Zirconia sensor, and its
heater assembly can be replaced on site. The detector is mounted, for example, on the wall of a
ue and can measure the gases directly.
For use in combustion gases at temperatures up to 1400°C, choose the general-purpose 0.15
m long detector, which is combined with ZO21P, the high temperature probe protector. The
converter is equipped with an LCD touch screen which has various setting displays, a calibration
display, oxygen concentration trend display, with easier operation and improvement of display
functions. The converter is equipped with various standard functions such as measurement
and calculation as well as maintenance functions including self-test. Analyzer calibration can
also be fully automated ─ and ZR40H, an automatic calibration unit, is available. Choose the
detector version which best suits your needs so that an optimal combustion control system can
be obtained.

Some examples of typical system congurations are illustrated below:
1.1 < EXAxt ZR > System Conguration
The system conguration should be determined by the conditions; e.g. whether calibration is
to be automated, and whether ammable gas is present and requires safety precautions. The
system conguration can be classied into three basic patterns as follows:
1.1.1 System 1
This system is for monitoring and controlling oxygen concentration in the combustion gases of
a large-size boiler or heating furnace. Clean (dry) air (21%O
the span gas for calibration. Zero gas is fed in from a cylinder during calibration. The gas ow is
controlled by the ZA8F ow setting unit (for manual valve operation).

1.1.2 System 2
This example, System 2, represents typical applications in large boilers and heating furnaces,
where there is a need to monitor and control oxygen concentration. The reference gas and
calibration-time span gas are (clean, dry) instrument air. Zero gas is supplied from a gas cylinder.
System 2 uses the ZR40H automatic calibration unit, with auto-switching of the calibration gas.
A “combustible gas detected” contact input turns off power to the heater. There’s also contact
output from the converter that can be used to operate a purge gas valve to supply air to the
sensor.
