r For the safe use of this equipment
CAUTION
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 measuring gas can damage the sensor.
• The detector (especially at the tip) becomes very hot. Be sure to handle it with gloves.
EXAxt ZR is very heavy. Handle it with care. Be sure not to accidentally drop it.
Handle safely to avoid injury.

1.Overview
The EXAxt ZR Separate-type Zirconia High-temperature Humidity Analyzer is used to
measure the humidity of hot gases continuously in driers which use hot gas or electricity
as the heat source. It can also be used in a variety of manufacturing applications in
humidifiers, as well as in driers, for humidity measurement and control. It can help
improve productivity in these application fields.
The ZR402G Separate-type converter is equipped with an LCD touchpanel which has
various setting displays, a calibration display, humidity 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 a self-test. Analyzer calibration can also be fully automated and ZR40H,
the automatic calibration unit, is provided. Choose the detector which best suits your
needs so that an optimal humidity control system can be obtained.
Some examples of typical system configuration are illustrated following pages :
1. Overview
IM 11M12A01-03E
1-1
1.1< EXAxt ZR > System Configuration
The system configuration should be determined by the conditions; e.g. whether the
calibration gas flow should be automated. The system configuration can be classified
into three basic patterns as follows:
1.1.1System 1
This is the simplest system consisting of a detector and a converter. This system can be
implemented for monitoring humidity in a production process such as food production.
No piping is required for the reference gas (air) which is fed in at the installation site.
The handy ZO21S standard gas unit is used for calibration.
Zero gas from this unit and span gas (air) is sent to the detector through a tube which is
connected during calibration.
CAUTION
• A needle (stop) valve should be connected to the calibration gas inlet of the detector.
The valve should be fully closed unless calibration is in progress.
• As this system uses ambient air for the reference gas, measuring accuracy will be
affected by the installation location.

1.1.2System 2
1. Overview
This system is for accurate monitoring and controlling humidity when the installation
environment is polluted with gases other than the air. Instrument air (clean and dry air
of oxygen concentration 21%) is used for the reference gas and the span gas for calibration. Zero gas is fed in from a cylinder during calibration. The gas flow is controlled by
the ZA8F flow setting unit (for manual valve operation).

This system is for accurate monitoring and controlling of humidity. Instrument air
(clean and dry air) is used for the reference gas and the span gas for calibration. Zero
gas is fed in from a cylinder during calibration. The calibration gas flow is controlled
automatically by the ZR40H automatic calibration unit.
This system is similar to system 2, except that the calibration gas flow is automated
using the ZR40H automatic calibration unit.

3.5E7044KF Case Assembly for Calibration-gas Cylinder
3.1Installation of the Detector
3.1.1Location
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 150°C, and the terminal box should not
affected by radiant heat.
(3) A clean environment without any corrosive gases.
3. Installation
CAUTION
• A natural convection type detector (model ZR22G-h-h-h-C), which uses ambient air
as reference gas, requires that the ambient oxygen concentration be constant.
(4) No vibration.
(5) The measurement gas satisfies the specifications described in Chapter 2.
(6) No measurement gas-pressure fluctuations.
IM 11M12A01-03E

3.1.2Probe Insertion Hole
Includes those analyzers equipped with a dust protector.
When preparing the probe insertion hole, the following should be taken into consider-
ation:
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 3.1 for the dimensions.
• If the detector is mounted horizontally, the calibration gas inlet and reference gas inlet
should face downwards.
When using the detector with pressure compensation, ensure that the flange gasket
does not block the reference air outlet on the detector flange. If the flange gasket
blocks the outlet, the detector cannot conduct pressure compensation. Where necessary, make a notch in the flange gasket. Confirm the external dimensions of the
detector in Section 3.7 before installation.
• The sensor (zirconia cell) at the probe tip may deteriorate due to condensation as it is
always at high temperature.
(1) Do not mount the probe with the tip higher than the probe base.
(2) If the probe length is 2.5 meters or more, the detector should be mounted vertically
(nomore than a 5° tilt).
(3) The detector probe should be mounted at right angles to the measurement gas
flow or the probe tip should point downstream.
Figure 3.1 illustrates an example of the probe insertion hole.
(vertical)
100mm
(Note)
When using the detector with ZH21B dust protector the diameter of the hole
should be 80mm or larger.

3.6Insulation 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 MV 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 kV resistance between the crossover wiring and ground to discharge.
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 arrester between
the terminal and ground is low.
8. After conducting all the tests, replace the jumper plate as it was.

detector is used for reference gas; therefore the accuracy of analysis will be affected
by ambient temperature changes or the like. If more accurate analysis is necessary,
use instrument air (dehumidified by cooling to the dew point –20°C or lower, and
removing any dust, oil mist and the like) for reference gas.
Stable analyzing can be conducted when using instrument air.

CAUTION
• The stop valve should be connected directly to the detector. If any piping is present
between the detector and the stop valve, water may condense in the pipe, which may
cause damage to the sensor by rapid cooling when the calibration gas is introduced.
The stop valve should be closed except while the calibration gas is being introduced.
Piping is required if the air around the detector is not clean.
• The reference gas should have an oxygen concentration identical to that of fresh air
(21%).

• It is recommended to use ZH21B dust protector to protect the probe output from dust
agitation (i.e., to prevent combustible materials from entering the probe cell) where
humidity measurements are made under dusty or combustible, such as paper dust,
environment.

4.2.2Piping for the Calibration Gas
This piping is to be installed between the zero gas cylinder and the ZA8F flow setting
unit, and between the ZA8F flow setting unit and the ZR22G detector.
The cylinder should be placed in a calibration gas unit case or the like to avoid any
direct sunlight or radiant heat so that the gas cylinder temperature does not exceed 408 C.
Mount a regulator valve (specified by YOKOGAWA) on the cylinder.
Mount a check valve or the stop valve (specified by YOKOGAWA) or the nipple (found
on the open market) at the calibration gas inlet of the detector as illustrated in Figure
4.8. (The check valve or the stop valve may have been mounted on the detector when
shipped.) Connect the flow setting unit and the detector to a stainless steel pipe 6 mm

however, the piping is basically the same as that of System 2. Refer to Section 4.2.
Adjust secondary pressure of both the air set and the zero gas reducing valve so that
these two pressures are approximately the same. The flow 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 Sec. 7.10.2), and
adjust zero gas reducing valve and calibration gas needle valve so that zero gas flow is
within the permitted range. Next check span gas calibration contact output and adjust
air set so that span gas flow is within the permitted range.

(4) Except when a “600V silicon rubber insulated glass braided wire” is used, connect
the cable shield to the FG terminal of the converter.
IM 11M12A01-03E
5.2.3Connection to the Converter
To connect the wiring to the converter, proceed as follows:
(1) M4 screws are used for the terminals of the converter. Each wire in the cable should
be terminated in the corresponding sige crimp-on terminal.
(2) When a rubber insulated glass braided wire is used for wiring to the detector, use a
terminal box. For wiring between the terminal box and the converter, use basically a
cable, e.g. PVC sheathed PVC insulated cable, rather than individual wires.
Note
The above is to prevent moisture or corrosive gas from entering the converter and to
ground the detector without fail.

Basically, PVC insulated PVC sheathed control cables (2 cores) are used for this wiring.
When the ambient temperature of the detector exceeds 808 C, install a terminal box, and
connect to the detector using six 600V silicon rubber insulated glass braided wires.
5.3.2Connection to Detector
When connecting the cable to the detector, proceed as follows:
(1) Mount cable glands or conduits of the specified thread size to the wiring connections
of the detector.
The detector may need to be removed in future for maintenance, so be sure to allow
sufficient cable length.
(2) If the ambient temperature at the location of wire installation is 80 to 1508 C, be sure
to use a flexible metallic conduit for the wire. If a non-shielded 0 600V silicon rubber
insulated glass braided wire 0 is used, keep the wire away from noise sources, to
avoid noise interference.
(3) The size of the terminal screw threads is M3.5. Each cable should be terminated in
the corresponding size crimp-on terminals (*1) respectively.

The following describes the minimum operating requirements — from supplying power
to the converter to analog output confirmation to manual calibration.
System tuning by the HART communicator, refer to IM11M12A01-51E “HART
Communication Protocol”
7.1Checking Piping and Wiring Connections
Check that the piping and wiring connections have been properly completed in accordance with Chapter 4, “Piping,” and Chapter 5, “Wiring.”
7.2Checking Valve Setup
Set up valves and associated components used in the analyzer system as follows
procedures:
7. Startup
(1) If a stop valve is used in the detector’s calibration-gas inlet, fully close this valve.
(2) If instrument air is used as the reference gas, adjust the air-set secondary pressure so
that an air pressure equals measured gas pressure plus approx.50 kPa (or measured
gas pressure plus approx. 150 kPa when a check valve is used, maximum pressure
rating is 300 kPa) is obtained. Turn the reference-gas flow setting valve in the flow
setting unit to obtain a flow of 800 to 1000 ml/min. (Turning the valve shaft counterclockwise increases the rate of flow. Before turning the valve shaft, if the valve has a
lock nut, first loosen the lock nut.) After completing the valve setup, be sure to
tighten the lock nut.
Note
The calibration-gas flow setting is described later. Fully close the needle valve in the
flow setting unit.

7.3Supplying Power to the Converter
CAUTION
To avoid temperature changes around the sensor, it is recommended that rather than
tuning it on and off power be continuously supplied to the High-temperature Humidity
Analyzer if it is used in an application where it is used periodically.
It is also recommended to flow a span gas (instrument air) beforehand.
Supply power to the converter. A display as in Figure 7.1, which indicates the detector’s
sensor temperature, then appears. As the heat in the sensor increases, the temperature
gradually rises to 7508 C. This takes about 20 minutes after the power is turned on,
depending somewhat on the ambient temperature and the measured gas temperature.
After the sensor temperature has stabilized at 7508 C, the converter is in measurement
mode. The display panel then displays the oxygen concentration as in Figure 7.2. This is
called the basic panel display.
