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 congurations are illustrated below:
1.1 < EXAxt ZR > System Conguration
The system conguration 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 conguration can be classied 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

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.

< Pressure setting for the ejector for high temperature use >
Pressure supply for the ejector should be set so that the suction ow of the sample gas becomes
approximately 5 L/min. To set this, proceed as follows:
(1) In Graph 4, draw a horizontal line from the 5 L/min point on the vertical axis (Suction ow:
Qg) toward the gas pressure line to be used, to nd the point of intersection. Draw a line vertically down from the point of intersection to the axis to nd the drive pressure, P (at the
ejector entrance).
(2) In Graph 1, determine Po (pressure setting) from L (the distance between the ejector and
the pressure gauge).
(3) Open the needle valve to supply air for the ejector to the pressure gauge until it indicates the
pressure setting, Po.
NOTE
Qg (the suction ow) may require change according to the conditions of use. Refer to Subsection
3.2.2 and Subsection 4.1.4 for details.
Graph explanation
1) Graph 1 is to compensate for pressure loss in piping between the ejector and the pressure
gauge, and nd Po (pressure setting).
2) Graph 2 shows correlation between P (drive pressure) and Qa (air consumption).
3) Graph 3 shows correlation between P (drive pressure) and Pg (suction pressure; when the sample gas inlet of the ejector is closed).
4) Graph 4 shows correlation between P (drive pressure) and Qg (suction ow) for each gas
pressure.

2.7.3 Check Valve (K9292DN, K9292DS)

This valve is mounted on the calibration gas line (directly connected to the detector). This valve prevents the sample gas from entering the calibration gas line. Although it functions as a stop valve, operation is easier than a stop valve as it does not require opening/closing at each calibration. Screw a check valve, instead of a stop valve into the calibration gas inlet of the detector.

3.1.6 Probe Insertion Hole

Includes those analyzers equipped with a probe supporter and probe protector. When preparing the probe insertion hole, the following should be taken into consideration:
CAUTION
• The outside dimension of detector may vary depending on its options. Use a pipe that is
large enough for the detector. Refer to Figure 3.6 for the dimensions.
• If the detector is mounted horizontally, the calibration gas inlet and reference gas inlet
should face downwards.
• The sensor (zirconia cell) at the tip of the detector may deteriorate due to thermal shock if
water drops are allowed to fall on it, as it is always at high temperature.
(1) Do not mount the probe with the tip higher than the probe base.
(2) The detector probe should be mounted at right angles to the sample gas ow or the probe
tip should point downstream.

The following should be taken into consideration when installing the detector: (1) Easy and safe access to the detector for checking and maintenance work. (2) Ambient temperature of not more than 60°C and the terminal box should not be exposed to
radiant heat. (3) A clean environment without any corrosive gases. (4) No vibration.
(5) The sample gas should satisfy the specications described in Chapter 2.
CAUTION
Be sure to read Subsection 3.1.2 to 3.1.5 where the important information on writing is provided.
IM 11M13A01-02E
<3. Installation>

3.2.2 Usage of High Temperature Probe Adapter (Model ZO21P)

During analysis, the surface temperature of the probe adapter should be within the range from more than the dew point of the sample gas and 300°C or less to prevent ejector clogging, gasket deterioration or bolt scoring.
Where the dew point of the sample gas is not known, keep within the range of more than 200°C to less than 300°C.
The temperature shall be measured at the probe in the probe adapter and the surface of the blind
ange at the opposite side.
When the surface temperature is not within the above range, the following measures can be taken to change the temperature.
CAUTION
When the surface temperature of ZR22S or ZO21P exceeds temperature class T2(300°C), this system shall not satisfy explosion-proof requirement for outside of the furnace.
<When the surface temperature exceeds 300°C>
3-9
(1) When the furnace pressure is negative, lower the pressure setting to reduce induction ow
of the sample gas. Refer to Subsection 2.7.1, Ejector Assembly for High Temperature, for the setting of
induction ow. When you reduce induction ow, ensure that the ejector inducts air when the furnace pressure uctuates.
(2) When the furnace pressure is positive, close the needle valve for the sample gas outlet to
reduce the exhaust gas ow. Refer to Subsection 4.1.5, Piping to the High Temperature
Probe Adapter.
(3) When the probe adapter is surrounded by a heat insulator, remove the heat insulator.
Ensure that the temperature of the probe adapter does not fall below the dew point of the gas in winter.
(4) To prevent temperature rises due to radiant heat, insert heat insulator between the wall of
the furnace and the probe adapter.
(5) To prevent temperature rises from thermal conduction, place the mounting ange as far
from the wall of the furnace as possible.
CAUTION
When a heater is used in hazardous area, then be sure to use appropriate explosion-proof heater and wiring conduit.
IM 11M13A01-02E
<3. Installation>
< When the surface temperature is less than 200°C or below the dew point of the sample
gas>
(1) When the furnace pressure is negative, raise the pressure setting to increase induction ow
of the sample gas. Refer to Subsection 2.7.1, Ejector Assembly for High Temperature, for the setting of
induction ow. If there is much dust in the gas, the ejector may become clogged as induction ow increases.
(2) When the furnace pressure is positive, open the needle valve of the sample gas outlet to
increase the gas ow. Refer to Subsection 4.1.5, Piping to the High Temperature Probe Adapter.
(3) Warm the probe adapter. Refer to Subsection 4.1.5, Piping to the High Temperature Probe
Adapter.
(4) When the surface temperature is still less than 200°C or below the dew point of the sample
gas, even if the above measures have been taken, warm the probe adapter using a heat source such as steam.

3.2.3 Probe Insertion Hole

A high temperature detector consists of a ZR22S--015 Detector and ZO21P High Temperature Probe Adapter. When forming the probe insertion hole, the following should be taken into consideration:
3-10
(1) If the probe is made of silicon carbide (SiC), the probe hole should be formed so that the
probe is mounted vertically (within ± 5° tilt).
(2) In the case where the probe is made of stainless steel and the probe adapter is to be
mounted horizontally, the probe hole should be formed so that the probe tip is not higher than the probe base.

3.6 Insulation Resistance Test

Even if the testing voltage is not so great that it causes dielectric breakdown, testing may cause deterioration in insulation and a possible safety hazard. Therefore, conduct this test only when it is necessary.
The applied voltage for this test shall be 500 V DC or less. The voltage shall be applied for as
short a time as practicable to confirm that insulation resistance is 20 MΩ or more.
Remove wiring from the converter and the detector.
1. Remove the jumper plate located between terminal G and the protective grounding terminal.
2. Connect crossover wiring between L and N.
3. Connect an insulation resistance tester (with its power OFF). Connect (+) terminal to the crossover wiring, and (-) terminal to ground.
4. Turn the insulation resistance tester ON and measure the insulation resistance.
5. After testing, remove the tester and connect a 100 kΩ resistance between the crossover wiring and ground, to discharge for over 1 min. During discharge, do not touch the terminal.
6. Testing between the heater terminal and ground, contact output terminal and ground, analog output/input terminal and ground can be conducted in the same manner.
7. Although contact input terminals are isolated, insulation resistance test cannot be conducted because the breakdown voltage of the surge-preventing arrestor between the terminal and ground is low.

4. Piping

This chapter describes piping procedures based on two typical system congurations for EXAxt
ZR Separate type Explosion-proof Zirconia Oxygen Analyzer.
• Ensure that each check valve, stop valve and joint used for piping do not allow leakage.
Especially, if there is any leakage of the calibration gas from pipes and joints, it may cause clogging of the pipes or incorrect calibration.
• Be sure to conduct leakage test after piping.
• Basically, apply instrument air (dehumidied by cooling to the dew point -20°C or lower, and
removing any dust, oil mist and the like) for the reference gas.
Do not loosen or remove any Flame Arrestor of gas inlet/outlet during piping.
The detector modication or parts replacement by other than authorized representative of Yokogawa Electric Corporation is prohibited and will void ATEX Certication, FM Approval, CSA Certication and IECEx Certication.

• When a high temperature detector is used and the sample gas pressure is negative,
connect an auxiliary ejector to the sample gas exhaust hole of the high temperature probe adapter (see Subsection 4.1.5, Figure 4.3).
• When a high temperature detector is used and the pressure of the measured gas is 0.5
kPa or higher, it is recommended that a needle valve (throttle) be used in the sample gas exhaust of the high temperature probe adapter (see Subsection 4.1.5, Figure 4.4).
CAUTION
This is for lowering the sample gas temperature below 700°C. If the gas temperature is high and
the pressure is also signicantly high, the sampled gas temperature may not reduced below
700ºC when reaching the detector. On the other hand, if the sample gas temperature is lowered too much, condensation may be produced in the high temperature probe adapter. During wintertime, it is recommended that the high temperature probe adapter should be protected with an insulating material to prevent condensation (see Figure 4.5). For the usage of the high temperature probe adapter, refer to Subsection 3.2.2.
• When a high temperature detector is used and blow back is required to eliminate dust
accumulating in the probe of the high temperature probe adapter, air supply piping for purging should be installed.
IM 11M13A01-02E
<4. Piping>
CAUTION
If a sample gas contains much dust (e.g., in recovery boilers or cement kilns), the probe is more likely to become clogged. To eliminate this dust accumulation using air pressure, piping is generally installed from an air source only when cleaning is performed. Some cases, however, may need a permanent installation of the blow back piping. See Subsection 4.2.5 for the installation of blow back piping.

4.1.3 Piping for the Reference Gas Inlet

Reference gas piping is required between the air source (instrument air) and the ZA8F ow setting unit, and between the ZA8F ow setting unit and the ZR22S detector.
Insert the air set next to the ow setting unit in the piping between the air source and the ow
setting unit. Use a 6 mm (O.D.) × 4 mm (I.D.) or larger (or nominal size 1/4 inch) stainless steel pipe between
the ow setting unit and the detector.

4.1.4 Piping for the Reference Gas Outlet

If the ZR22S is exposed to rain or water splash, connect the pipe outlet on downward.

4.1.5 Piping to the High Temperature Probe Adapter

• The sample gas should be at a temperature below 700°C before reaching the detector sensor. If the gas is under negative pressure, it should be fed to the detector by suction.
• For usage of the high temperature probe adapter when using high temperature detector,
refer to Subsection 3.2.2.
• If the sample gas is under negative pressure, connect the ejector assembly (E7046EC/
E7046EN) as illustrated in Figure 4.3. Mount the pressure gauge as close as possible to the ejector. However, if the ambient temperature is too high, mount the gauge in a location with a temperature below 40°C.

If the temperature of the sample gas is high and its pressure exceeds 0.49 kPa, the temperature of the sample gas at the detector may not be below 700°C. In such a case, connect a needle valve (found on the local market) through a nipple (also found on the local market) to the sample gas outlet (Rc1/2) of the probe adapter so that the sample gas exhaust volume is restricted.
In cases where condensation is likely to occur in the probe adapter when the sample gas is cooled, protect the probe adapter with an insulating material as illustrated in Figure 4.5.

4.2.2 Piping for the Calibration Gases

The piping for the calibration gases should be installed between the calibration gas cylinders (or instrument air source) and the detectors with the ZR40H automatic calibration unit.
Figure 4.7 shows the ZR40H Automatic Calibration Unit piping diagram. Adjust secondary pressure of both the air set and the zero gas pressure reducing valve so that
these two pressures are approximately the same. The ow rate of zero and span gases (normally
instrument air) are set by a single needle valve. After installation and wiring, check the calibration contact output (see Subsection 7.11.2), and
adjust zero gas pressure reducing valve and calibration gas needle valve so that zero gas ow is
within the permitted range. Next check span gas calibration contact output and adjust air set so
that span gas ow is within the permitted range.

5.5.2 Grounding Wiring

The ground wiring of the detector should be connected to the ground terminal of the detector case. The ground wiring of the converter should be connected to either the ground terminal of the converter case or the protective ground terminal in the equipment. The grounding terminals of the detector are of size of M4 (inside) and M5 (outside), and the grounding terminals of the converter are of size M4. Proceed as follows:
(1) Keep ground resistance to 100 Ω or less.
(2) When the ambient temperature of the wiring installation is 75 to 150°C for the wiring of the
detector, use wiring material with sufcient heat resistance.
(3) When connecting the ground wiring to the ground terminal of the converter case, be sure
that the lock washer is in contact with the case surface (see Figure 5.9.).
(4) Ensure that the jumper plate is connected between the G terminal and the protective ground
terminal of the converter.
(5) No intermediate parts are used for the internal ground terminal of the detector. Use crimping
terminal for connection to the internal ground terminal in order to avoid corrosion by high contact potentials.
(6) In order to prevent the earthing conductor from loosening, the conductor must be secured
to the terminal, tightening the screw with torque of approx. 1.2 N•m (for M4) or 2.0 N•m (for
M5).

To enter a password (in combination with text data, numeric values and codes), the alphabetic
character entry panel display rst appears. If you press any numeral key [0 - 9], the current
display then changes to the numeric-value entry panel display, enabling you to enter numeric
values. If you press the [other] key, the current display then changes to the code-entry display,
enabling you to enter codes. These displays alternate between the three. Figure 6.7 shows the relationship between these three displays. Three alphabetic characters and three codes are assigned for each individual switch. If the alphabetic character key is pressed and held, three characters appear in turn. Move the cursor to the desired character and release the key to enter it. If an incorrect character is entered, move the cursor to re-enter the characters. The following shows an example of entering “abc%123.”
