CAUTION
Caution on piping
In 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.
• Connect pipes correctly referring to the instruction manual.
• Exhaust should be led outdoors so that it will not remain in the locker and installation room.
• 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.
3 - 2 IM 11G02M01-01E
Observe the following when connecting the gas pipes.
The pipes should be connected to the gas inlet and outlet at the rear panel of the analyzer, respectively.
Connect the sampling system to the instrument by using corrosion-resistant tube such as Teflon, stainless steel, or polyethylene. In case where there is no danger of corrosion, don't use rubber or soft vinyl tube. Analyzer indication may become inaccurate due to the adsorp­tion of gases.
Piping connections are Rc1/4 (1/4 NPT) female-threaded. Cut the pipe as short as possible for quick response. Pipe of ø 4mm (inside diameter) is recommendable .
Entry of dust in the instrumant may cause operation fault. Use clean pipes and couplings.

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.
(5) Purging of instrument inside
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 installa­tion site.
In such cases as above, the inside of analyzer should be purged with the air for instrumentation

4. OPERATION

4.1 Preparation for operation

(1) Check of gas sampling tube, exhaust tube and wiring
Check that the pipes are correctly connected to the gas sampling port and drain port. Check that the analyzer is correctly wired as specified.

4.2 Warm-up operation and regular operation

(1) Operation procedure
1. Turn ON the power switch at the left of the front panel. In one or two seconds, the measurement screen will appear at the front panel.
2. About 2 hour warm-up operation About 2 hours are needed until the operating performance is stabilized. Warm-up operation
should be continued with the power ON.
3. Setting of various set values Set required set values according to Chapter 6, “Setting and calibration”.
4. Zero and span calibration Perform zero calibration and span calibration after warm-up operation. See Chapter 6.9, “Calibration”.
5. Make moisture interference compensation adjustment (NO Analyzer and SO (See “6.8 Maintenance mode” and “7.4 Moisture interference compensation adjustment” for details.)
Be sure to perform individual moisture interference compensation adjustment according to the system in the case of NO Analyzer and SO affected by moisture interference.
6. Introduction and measurement of measured gas Start measurement by introducing measured gas into the analyzer.
2 Analyzer. Otherwise measurement is
2 Analyzer).
Note) While in warm-up operation, the concentration reading may be beyond the
upper limit of the range (range-over) or below the lower limit (range-under) .
But this is not an error.

• Alarm Count : 1 to 99 times (initial value: 5 times)
• Hysteresis : 0 to 20% of full scale (initial value: 0% of full scale) * The hysteresis setting is made in terms of full scale.
Action of peak alarm
Example
(ON)
(OFF)
If CO concentration exceeds the alarm value, counting will begin. If the number of peaks is over the set times per hour, a peak count alarm 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 alarm
To release the peak alarm, set the peak alarm to OFF. Turning on the peak alarm initiates counting from 0.

7.5 Cleaning of measuring cell

Entry of dust or water drops in the measuring cell contaminates the interior of the cell, thus result­ing in a drift. Clean the inside if dirty. Then, check the sampling device, especially the filter, to prevent the cell from being contaminated by dust or mist.

7.5.1 Disassembly and assembly of measuring cell

There are two kinds of measuring cells, on block cells (cell length: 4 mm, 8 mm, 16 mm, 32 mm) and pipe cells (Cell length: 64 mm, 125 mm and 250 mm).
2-component analyzer may incorporate both measuring cells in optical unit. In such a case, detach the pipe cell and then block cell (See Fig. 7-1).
(1) How to remove pipe cell (See Fig. 7-1)
1. Stop measured gas. If it is harmful, purge in the measuring cell thoroughly with zero gas.
2. Turn OFF the power switch.
3. Detach the top cover.
4. Remove the pipe connected to the measuring cell.
5. Slide the infrared ray light source unit (No. 5) toward the front panel by loosening the screw (No. 1) fastened to the base plate to provide clearance between the pipe cell (No. 12) and light source unit.
6. Loosen and remove a screw (No. 7) from the cell retainer (No. 11) fastening the pipe cell.
7. Remove the cell from the measuring unit and unscrew the infrared transmission window (No.
14) at the both ends in the right direction.
Note) The reflection plate in the cell is not closely attached to the cell.
8. For assembly, reverse the disassembly procedure. Provide 0.5 mm clearance between the infrared ray light source unit and cell, and the cell and detector, respectively.

5. Remove the connector to the detector output cord from the printed board. For the 2-compo­nent analyzer, remove the output cord connector of the 2-component analyzer detector (No.
13) from the printed board, and then remove the 2-component detector by unscrewing two mounting screws (No. 14) fastening the 2-component detector.
6. Unscrew the two screws (No. 10) that hold the detector to the infrared ray light source unit to remove the detector from the measuring unit. The cell can be removed together with the detector.
7. To remove the cell, unscrew the two screws (No. 6) holding the cell to the detector. The infrared transmission window is just sandwiched (not fixed) between the detector and block cell. Keep the detector facing up, when removing this window.
8. For assembly, reverse the disassembly procedures.
Note) The O-ring is placed between the window holder and cell. Take care about the O-
ring position. With 2-component analyzer, install 2-component detector last. Take care so that no space is left between the 1-component and 2-component detectors. When inserting the detector output cord connector into the printed board, plug the connectors for 1-component detector and 2-component detector into position. The 1-component connector should be plugged into CN11 and 2-component connector into CN1, respectively.

7.5.2 How to clean cell

1. To clean the cell inside or infrared ray transmission window, first clear large dirt of it with a soft brush and then wipe with soft cloth lightly.
Don’t use hard cloth.
Note) Handle the fragile window with care. Use care not to rub off the dirt from the
window roughly.
2. If the window or the cell interior is very dirty, use a soft cloth moistened with absolute alcohol.
3. If the window is corroded, rub off the scale from the window lightly with a soft cloth to which chrome oxide powder is applied. If it is excessively corroded, it should be replaced with new one.
4. When cell or window cleaning is completed, assemble according to the cell disassembly and assembly procedures. Especially, the pipe should be closely connected without gas leak, and repair if the pipe is bent.

7.6 Inspection and maintenance of limited service-life components

The analyzer uses limited-life components. The recommended replacement periods are listed in the below table.
1. Limited service-life components are those which wear out or for which failure is presumed within five years under normal operating or storage conditions. Components with more than five years of service life are the exception.
2. The previous table only involves the recommended periods for conducting preventive main-
tenance for limited service-life components; these periods do not guarantee that accidental failures will not occur.
3. The recommended replacement preiods are tentative and depend on operating conditions.
4. The recommended replacement preiods may vary depending on the field date.

(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. Indication values will not be held.
Remote output holding:
Output signal is held at the latest value by short-circuiting the remote output hold­ing input terminals. Holding is maintained while the terminals are short-circuited. Indication values will not be held.
Remote range changeover:
Measuring range can be changed accord­ing to an external signal when remote range changeover input is received. Changeover is effective only when remote range setting is turned on. In this case, measuring range cannot be changed manually. When the contact input terminals for each component are short-circuited, the first range is selected, and it is changed over 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 component 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 calibra­tion and a solenoid valve for opening/clos­ing 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 calibration 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 599 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 cyclic auto calibration. Calibration starts when a non-voltage rectangular wave is applied to the auto calibration remote start input terminals (opened after short-circuiting for 1.5 sec­onds or longer). Auto calibration is started when the contacts open.
Auto zero calibration:
Auto zero calibration is carried out peri­odically at the preset cycle. This cycle is independent on “Auto cali­bration” 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 599 seconds (in increments of 1 second)
Upper/lower limit alarm:
Alarm contact output turns on when the preset upper or lower limit alarm value is reached. Contacts close when the instantaneous value of each component becomes larger than the upper alarm limit value or smaller than the lower 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 calibrationl.
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.

Used for averaging is the moving aver­age method in which sampling is carried out at intervals of 30 seconds. (Output is updated every 30 seconds. 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).
Average value reset:
The above-mentioned output of average value is started from the initial state by applying a non-voltage rectangular wave to the average value resetting input ter­minals (opened after short-circuiting for
1.5 seconds or longer). Output is reset by short-circuiting and restarted by opening.
CO concentration peak count alarm:
