(1) Mounting method

Mount so that the front panel is vertical.

(2) Caution on installation

70% or more of the instrument weight should be supported by the case bottom. (When mounting on a panel or 19 inch rack, attach a support under the rear of the case.)

3.2 Piping method

DANGER

• Use clean pipes of which inside should not be stained with deposits of oil or fat.

• Piping joints must be tightened firmly to avoid gas leakage.

• Exhaust gas should be discharged to an outdoor safe place to prevent it from staying in the

sampling device and indoors.

• Exhaust from the analyzer should be relieved at the atmospheric pressure 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.

(1) Piping procedure

Connect pipes to the gas inlets and outlets located at the top left on the analyzer rear. 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) 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.

Carry out gas piping as follows.

Purge gas inlet : Connect purge gas pipe here.

Reference gas outlet : Connect pipe here for discharging reference gas.

Reference gas inlet : Connect reference gas here in case of flow differential system.

Sample gas outlet : Connect pipe here for discharging measured gas.

Sample gas inlet : Connect gas to be measured here.

3.3 Sampling

3.3.1 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 accumula-

tion 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 SO

(4) Note that if strongly corrosive gas such as Cl

temperature gas directly into the analyzer.

3.3.2 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)

3.3.3 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

(Span gas in measuring method is gas with concentration of 90% or more of full scale.)

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. (Span gas in measuring method is gas with concentration of 90% or more of full scale.)

Note: When calibrating the low and high ranges of Zirconia type O2 analyzer, use 9 to 10% O2/N

for the low range, and air for the high range.

3.3.4 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 installa-

tion site.

In such cases, purge the analyzer interior with instrumentation air or N should be about 1r/minute.

And dust or mist should be completely eliminated from the gas for purging.

3.3.5 Pressure at sample gas outlet

Arrange so that the sample gas outlet is at atmospheric pressure.

3.4 Wiring method

CAUTIONS

: Turn OFF all the power before starting a wiring work to prevent a risk of electric

shocks.

: Be sure to enforce construction of specified grounding.

The external terminals are provided on the rear of the instrument. Carry out wiring to each terminal according to the figure. Terminal screws are M3.5 (but power

terminals are M4). Use shielded wires for the output signals to suppress the influence of external noise.

3.4.1 Power terminals

The power terminals are arranged as shown in the figure. 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.

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.
