1. OVERVIEW

This infrared gas analyzer (type: IR400) measures the concentration of NO, SO2, CO2, CO and CH

contained in sampling gas on the principle that different atomic molecules have an absorption spectrum in the wave band of infrared rays, and the intensity of absorption is determined by the Lambert-Beer law.

Since this instrument incorporates a compact paramagnetic O components simultaneously by using the built-in O

sensor (up to 4 components if O2 sensor is excluded).

sensor, it allows measuring up to 5

Furthermore, use of a microprocessor or large sized liquid crystal display realizes improvement of operability, accuracy and multi-functions.

This instrument is optimum for measuring combustible gas exhausted from boilers or incinerators, and it is effective for steel gas analysis (blast furnace, steel converter, thermal treatment furnace, sintering (Pellet equipment), coke furnace), storage and maturity of vegetable and fruit, biochemistry (microbe), [fermentation], air pollution [incinerator, exhaust gas desulfurization, denitration], automotive emission (excluding tester), protection against disasters [detection of explosive gas and toxic gas, combustion gas analysis of new building material], growth of plants, chemical analysis [petroleum refinery plant, petroleum chemistry plant, gas generation plant], environment [landing concentration, tunnel concentration, parking lot, building management] and various physical and chemical experiments.

3.3 Piping

Piping should be connected to the gas inlets and outlets of the front panel of the analyzer.

• Use a corrosion resistant tube of Teflon, stainless or polyethylene to connect the instrument to

a sampling system. Even if there is a danger of corrosion, refrain from using a tube of rubber or soft vinyl. The instrument provides inaccurate indication due to gas absorption by piping materials.

• Pipe connection port is Rc1/4 female thread (or 1/4 NPT). Piping should be cut as short as

possible for a quick response. About 4 mm inner diameter is recommended.

• Entry of dust into the instrument may result in defective operation. Use a clean piping or

coupling.

Connect the gas tube by the following method.

Sampling gas outlet

For measuring unit 1

Sampling gas inlet

Sampling gas outlet (Purge gas inlet)

For measuring unit 2

Sampling gas inlet: Attach the gas tube to introduce gas to be measured such as one that has

completed dehumidification process and standard gases for zero and span calibration to this inlet. Gas flow to be introduced should be constant within the range of 0.5 ± 0.2 L/min.

Sampling gas outlet: Exhaust measured gas through the outlet. Attach the tube to exhaust mea-

sured gas outdoors or to the atmosphere.

Purge gas inlet: It is used for purging the inside of the total gas analyzer . When the ana-

lyzer must be purged, refer to Item 3.3.4 Purging of instrument inside. Use dry gas N

or instrumentation air for purge gas. (flow rate of 1L/min or

more should be used and no dust or mist is contained).

3.4 Sampling

3.4.1 Conditions of sampling gas

1. Dust contained in the sampling gas should be completely removed with a filter. For the final stage filter, use a filter that allows removing dust particles of 0.3mm.

2. Dew point of sampling gas must be lower than the ambient temperature to avoid occurrence of drain in the gas analyzer. If vapor is contained in the sampling gas, dew point should be lowered to 0°C by using a dehumidifier.

3. If SO

4. Corrosive gases such as Cl

5. Temperature of sampling gas should be within 0 to 50°C. Provide a means that prevents

3.4.2 Sampling gas flow

Flow of sampling gas should be 0.5 ± 0.2L/min. Avoid flow fluctuation during measurement. Observe the flow reading by a flowmeter provided as shown in the example of the sampling

system configuration (Item 3.4.6).

2 measurement is subject to moisture interference.

As shown by the configuration example on the next page, provide a device for humidifying zero calibration gas, thus controlling the moisture content at a constant level (moisture content in sample gas should also be controlled here) in configuring a sampling system. That allows the same moisture content as in the case of measurement to be contained in zero gas for calibration.

The inside of instrument need not be purged generally except for the following cases.

1. A combustible gas component is contained in sample gas.

2. Corrosive gas is contained in the atmospheric air at the installation site.

3. The same gas as the sample gas component is contained in the atmospheric air at the installa-

tion site.

In such cases as above, the inside of analyzer should be purged with the air for instrumentation or N2. Purging flow rate should be about 1L/min. If dust or mist is contained in purging gas, it should be eliminated completely in advance.

Description of setting items

• Peak Alarm : ON/OFF of peak alarm

• Alarm Value : If measuring value exceeds the set alarm value, a peak counter counts 1 time.

• Alarm Count : When a peak in excess of the setting

time occurs, a peak count alarm output

is provided.

• Hysteresis : To prevent possible chattering when the measuring value may exceed the set peak concentration by only 1 time, the peak count has an allowance in the hysteresis width.

Setting range

Alarm value : 10 to 1000 ppm 5 ppm step (initial value: 500 ppm) Alarm count : 1 to 99 times (initial value: 5 times) Hysteresis : 0 to 20 % of full scale (initial value: 0% of full scale)

[% full scale] represents the percentage with the CO range regarded as 100%.

Action of peak alarm

Example

If CO concentration exceeds the alarm value, counting will begin. If the number of peaks is over the set times per hour, a peak alarm contact output becomes closed (ON). If it is less than the set times per hour, it is open (OFF). Since 5 times of peaks /hour is marked at (1) section from the above graph, the peak count alarm is turned ON. Since peaks of more than 5 times per 1 hour occur at the interval between (1) and (2) , the peak count alarm remains ON. Since at (2), peaks are reduced to 4 times per hour, it is turned OFF.

Like the hysteresis of the alarm setting , the hysteresis prevents possible chattering when measured gas is fluctuated near the alarm value.

* For 10 minutes after the power is turned ON, a peak alarm counting is not carried out.

Releasing peak count alarm

To release the peak count alarm, set the peak alarm to OFF. Turning on the peak alarm initiates counting from 0.

7.3.5 Replacement of fuse on analyzer unit

Note) Before the following work, be sure to remove the cause of blown fuse (short, etc) and

repair.

(1) Turn OFF the main power supply SW of the analyzer. (2) Loosen setscrews (4 pcs.) from the top of the analyzer and remove the top cover. (3) Turn the fuse holder (shown in Fig. 7-3) counterclockwise and put it out, and the cap will be removed. Remove the fuse (250 V AC/3 A) from the holder. Replace it with a new one . (4) Mount the fuse holder cap and cover for analyzer indication unit in the reverse procedure. Turn ON the power supply SW. The work will be completed if the analyzer is normally worked.

d Precautions to be taken while checking

(1) When handling reference gas (during calibration), carefully read the reference-gas instruc-

tion manual to use the gas correcrtly. In particular, special attention must be taken in handling carbon monoxide gases; otherwise, you may suffer from gas poisoning.

(2) During maintenance checks, be sure to keep the near fan on. If any gas leaks, you may suffer from gas poisoning.

(3) When replacing the analyzer gas filter or conducting maintenance service of the washer, completely shut the calibration-gas valve. Otherwise, you may suffer from gas poisoning.

2. Standard Functions

Output signal holding:

Output signals are held during manual and auto calibrations by activation of holding (turning “ON” its setting). The values to be held are the ones just before start calibration mode or setting value. It is selectable. Indication of instantaneous values will not be held.

Remote output holding:

Output signal is held at the latest value or setting value by short-circuiting the remote output holding input terminals. Holding is maintained while the terminals are short-circuited.Indication of instantaneous values will not be held.

Switch ranges:

The switch ranges is available in manual, auto, and remote modes. Only preset

switch method is effective. Manual: Allows range to switch by key operation. Auto: Allows range to switch from low to high

range when 90%FS or more is available in

the low range.

Allows range to switch from high to low

range when 80%FS or less is available in

the low range. Remote: No-voltage contact input (for measurable

components)

Allows range to switch via an external sig-

nal when remote range switch input is re-

ceived.

When the contact input terminals for each

component are short-circuited, the first

range is selected, and it is switched to the

second range when the terminals are open.

Range identification signal:

The present measuring range is identified

by a contact signal.

The contact output terminals for each com-

ponent are short-circuited when the first

range is selected, and when the second

range is selected, the terminals are open.

Auto calibration:

Auto calibration is carried out periodically at

the preset cycle.

When a standard gas cylinder for calibra-

tion and a solenoid valve for opening/clos-

ing the gas flow line are prepared externally

by the customer, calibration will be carried

out with the solenoid valve drive contacts

for zero calibration and each span calibra-

tion turned on/off sequentially at the set

auto calibration timing. Auto calibration cycle setting:

Auto calibration cycle is set. Setting is variable within 1 to 99 hours (in increments of 1 hour) or 1 to 40 days (in increments of 1 day).

Gas flow time setting:

The time for flowing each calibration gas in auto calibration is set. Settable within 60 to 900 seconds (in increments of 1 second)

Auto calibration remote start:

Auto calibration is carried out only once according to an external input signal. Calibration sequence is settable in the same way as the general auto calibration. Auto calibration is started by opening the auto calibration remote start input terminals after short-circuiting for 1.5 seconds or longer.

Auto zero calibration:

Auto zero calibration is carried out periodically at the preset cycle. This cycle is independent on “Auto calibradion” cycle. When zero calibration gas and solenoid valve for opening/closing the calibration gas flow line are prepared externally by the customer, zero calibration will be carried out with the solenoid valve drive contact for zero calibration turned on/off at the set auto zero calibration timing.

Auto zero calibration cycle setting:

Auto zero calibration cycle is set. Setting is variable within 1 to 99 hours (in increments of 1 hour) or Setting is variable within 1 to 40 days (in increments of 1 day)

Gas flow time setting:

The timing for flowing zero gas in auto zero calibration is set. Settable 60 to 900 seconds (in increments of 1 second)

Upper/lower limit alarm:

Alarm contact output turns on when measurement value reach to the preset high or low limit alarm value. Contacts close when the channel value of each channel becomes larger than the high alarm limit value or smaller than the low alarm limit value.

Instrument error contact output:

Contacts close at occurrence of analyzer error No. 1, 3 or 10.

Calibration error contact output:

Contacts close at occurrence of manual or auto calibration error (any of errors No. 4 to 9).

Auto calibration status contact outputs:

Contacts close during auto calibration.

Pump ON/OFF contact output:

During measurement, this contact close. While calibration gas is flowing, this contact open. This contact is connected in power supply of pump, and stop the sample gas while calibration gas flowing.

It is the average value in the determined period of time just before the latest updating.) Averaging time is settable within 1 to 59 minutes (in increments of 1 minute) or 1 to 4 hours (in increments of 1 hour).

The above-mentioned output of average value is started from the initial state by opening the average value resetting input terminals after short-circuiting for 1.5 seconds or longer. Output is reset by short-circuiting and restarted by opening
