1. OPERATION PRINCIPLE
1.1 Standard type
The infrared rays radiated from the infrared light source is divided into two parts by the distributing
cell to be incident upon the sample cell and reference cell, respectively. Interference gas is sealed in
the distributing cell to lessen the influence of the interference gas contained in the sample gas. The
infrared ray is absorbed by the sample gas in the sample cell, and the transmitted light quantity is
reduced by the absorbed quantity. Meanwhile, such a gas that does not absorb the infrared ray is
sealed in the reference cell, so the infrared ray is transmitted without being absorbed. The rotary
chopper provided between the infrared light source and distributing cell turns on a cycle of approx.
9Hz. Therefore, a larger quantity of infrared ray and a smaller quantity of infrared ray are incident
to the detector simultaneously on a cycle of approx. 9Hz. A Fuji unique mass flow type detector is
employed as this detector. This detector converts the difference between these light quantities into a
resistance variation, and generates an AC signal of approx. 9Hz. Furthermore, this detector functions as an interference compensation detector which lessens the influence of the interference gas
contained in the sample gas by a special method.

1.2 Sample switching type
The following description is given on the infrared carbon monoxide analyzer. However, this analyzer makes the similar action in case of other components.
The sample switching type infrared analyzer is based on a basic operation principle that the carbon
monoxide has a unique infrared ray absorption spectrum. The monoxide is measured by a flow route
changeover and flow differential system with the sample gas through a carbon monoxide/carbon
dioxide converter set to zero gas.
One of the sample gases processed by the pre-processor gets in the sample cell of the analyzer, while
the other is converted into a gas containing no carbon monoxide through the CO/CO2 converter, and
it is put in the reference cell. The flow routes of these gases are changed over to each other by a
solenoid valve every 50 seconds, using the solenoid valve drive signal sent from the main printed
circuit board.
The sample cell and reference cell are provided with infrared-ray transmitting windows at both ends.
The sample gases are exposed to the infrared rays which are transmitted through these windows, and
absorb the infrared rays according to the measurement component.
The sample gas through the CO/CO2 converter does not absorb the infrared ray of the wave-length
peculiar to the carbon monoxide, while the sample gas containing the carbon monoxide put in the
sample cell absorbs the infrared ray.
The infrared rays transmitted through these two cells are incident upon the reference side detector
vessel and sample side detector vessel, respectively. The pressure of the detector vessel on the
larger light quantity side (the side of the sample gas through the CO/CO2 converter) becomes higher
than that of the other detector vessel. Therefore, the gas flows from the reference side to the sample
side at the moment of making the infrared ray incident upon the detector vessels, but it flows reversely at the moment of interrupting the infrared rays.
This flow is converted into an AC voltage by the mass flow sensor. This AC voltage is subjected to
A/D conversion and digital processing.

3. PIPING AND WIRING
3.1 Piping method
DANGER
On piping, the following precautions should be observed. Wrong piping may cause gas
leakage.
If the leaking gas contains a toxic component, there is a risk of serious accident being induced.
Also, if combustible gas is contained, there is a danger of explosion, fire or the like occurring.
Also, if combustible gas is contained, there is a danger of explosion, fire or the like occurring.
• Connect pipes correctly referring to the instruction manual.
• Exhaust gas should be led outdoors so that it will not remain in the sampling device and
indoors.
• Exhaust from the analyzer should be relieved in the atmospheric air in order that an unnecessary pressure will not be applied to the analyzer. Otherwise, any pipe in the analyzer
may be disconnected to cause gas leakage.
• For piping, use a pipe and a pressure reducing valve to which oil and grease are not adhering. If such a material is adhering, a fire or the like accident may be caused.
(1) Piping procedure
Connect pipes to the gas inlets and outlets located at the rear top of the analyzer.
Use anticorrosive tubes made of Teflon, stainless steel, polyethylene or the like for connecting the
analyzer and sampling system. Avoid using rubber or soft vinyl tubes even if there is no worry about
corrosion. Improper piping material may cause inaccurate indication due to adsorption of gas.
The pipe connections are Rc1/4 (PT1/4) or NPT1/4 internal thread. And the pipes should be kept as
short as possible to quicken the response. A suitable inner diameter is about 4mm. Note that dust
entering the analyzer may cause a malfunction, so be sure to use clean pipes and joints.

3.2 Sampling
3.2.1 Sample gas condition
(1) Remove all dust included in sample gas by means of a filter. Use a filter capable of eliminating
dust particles of 0.3µ at the final stage.
(2) The dew point of sample gas must be lower than the ambient temperature to prevent accumulation of drain inside the analyzer. If water vapor is included in the sample gas, then feed the gas
through a dehumidifier to lower the dew point to around 0°C.
(3) If SO3 mist is included in sample gas, then use a mist filter, cooler etc. to exclude the mist. The
same applies if other kinds of mist are included.
(4) Note that if strongly corrosive gas such as Cl2, F2 or HCr is included in sample gas in a large
amount, it will shorten the service life of the analyzer.
(5) The sample gas temperature should range from 0 to 50°C. Be careful not to introduce a high
temperature gas directly into the analyzer.
3.2.2 Sample gas flow rate
The sample gas flow rate should be as follows.
Provide a flowmeter as shown in the preceding diagram to measure the flow rate.
Standard type
0.5r±0.25r/minute
Sample switching type
(1r+1r)±0.1r/minute (sample gas+reference gas)
Flow differential type
(0.5r+ 0.5r)±0.25r/minute (sample gas +reference gas)

3.2.3 Preparation of standard gas
Prepare standard gas for zero point and span point calibration.
Zero gas
N2 gas
Span gas
Gas with concentration of 80% or more of full scale for each component
When using a Zirconia O2 analyzer, use air for zero gas.
Zero gas
Air (O2 analyser span gas in measuring method) Note)
Span gas
1 to 2% O2 (O2 analyser span gas in measuring method)
Gas with concentration of 80% or more of full scale for other than Zirconia O2 analyzer.
Note: When calibrating the low and high ranges of Zirconia type O2 analyzer, use 9 to 10% O2/N2
for the low range, and air for the high range.
3.2.4 Analyzer interior purging
Although purging of the analyzer interior is normally unnecessary, it should be considered in the
following cases.
(1) When combustible gas is included in the measured gas
(2) When corrosive gas is included in the atmosphere at the installation site.
(3) When the same gas as the measured components is included in the atmosphere at the installation site.
In such cases, purge the analyzer interior with instrumentation air or N2. The flow rate for purging
should be about 1r/minute.
And dust or mist should be completely eliminated from the gas for purging.
3.2.5 Pressure at sample gas outlet
Arrange so that the sample gas outlet is at atmospheric pressure.

3.3 Wiring method
CAUTIONS
• Wiring is allowed only when all power supplies are turned off. This is required for preventing a shock hazard.
• Enforce construction of class-3 grounding wire by all means. If the specified grounding
construction is neglected, a shock regard or fault may be caused.
• Wires should be the proper one meeting the ratings of this instrument. If using a wire
which cannot endure the ratings, a fire may occur.
• Use power source that matches the rating of the unit. Use of power source out of rating
may cause fire.
The external terminals are provided on the rear of the instrument.
Carry out wiring to each terminal according to the figure. Terminal screws are M3 (but power
terminals are M4).
Use shielded wires for the output signals to suppress the influence of external noise.

3.3.1 Power terminals
Grounding wire
The power terminals are arranged as shown in the figure.
Power supply
Connect the specified power supply to the terminals and
connect a grounding wire to the ground terminal.
The grounding should be made securely.
Use solderless terminals (for M4) for connection to the
terminals.
E
Source
When the noise generating source is located nearby
Avoid installing this analyzer near an electrical apparatus which produces power source noise. (Such as
high frequency furnace, electric welder, etc.) If use of
the analyzer near such an apparatus is unavoidable,
then keep the power lines separate to avoid noise.
If noise from a relay, solenoid valve or the like enters
the power source, then attach a varistor or a spark
killer to the noise source as shown in the figure.
Note that attaching the varistor or spark killer away
from the noise source will be ineffective.

6. MAINTENANCE
If dust or water drips get in the measurement cell, its interior is contaminated and a drift may occur.
Since an error code is indicated if measurement or calibration is disabled, check if the measurement
cell is contaminated. When its is contaminated, clean it in the procedure given in this chapter.
At the same time, check the sampling devices, particularly, the filter to prevent the cell interior from
being contaminated by dust, mist or the like.
6.1 How to clean sample cell (pipe cell)
This unit is strictly adjusted prior to delivery from the factory, and special care should be taken
when handling it.
(1) To purge the sample cell, turn off the
power switch and stop the flow of sample
gas and flow zero gas for a few minutes.
Loosen the knurled knobs (2 pieces) on the
front panel and pull out the analyzer
interior by means of the grips.

When the sample cell is reassembled after having been removed for cleaning or the like, this
adjustment should be carried out before use. Following is the adjustment procedure.
(1) First carry out electrical zero adjustment.
With the power turned off, detach the connectors CN2 and 3 (for 1st component) and CN4 and
5 (for 2nd component) leading from the detector which are connected with the main PCB (2).
Next, turn on the power and calibrate the zero point using ZERO and CAL keys.
(2) Turn off power, connect the connectors CN2 and 3 (1st component) and CN4 and 5 (2nd
component), and turn on power again. Supply dry nitrogen from the sample gas inlet and wait
until the indication stabilizes.
(3) Set up the optical zero adjustment mode as
in section 4.2.3. The following indications
will appear on the main and sub indicators
of the analyzer front panel.
