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 0.3µm.
(2) Dew point of the 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 2˚C by using a dehumidifier.
(3) If SO
3
mist is contained in the sampling gas, use a mist filter or cooler to remove SO
3 mist.
Other mists should be removed by using a mist filter or gas dryer.
(4) Corrosive gases such as Cl
2
, F
2
and HCl, if they are contained in the sampling gas in considerable amounts, will shorten the life of component parts.
(5) Temperature of the sampling gas should be within 0 to 50˚C. Pay attention not to flow hot gas directly into the instrument.
3.4.2 Sampling gas flow
Flow of sampling gas should be 1.0L/min ± 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 (Section 3.4.6).
3.4.3 Preparation of standard gas
Routine calibration is required by standard gas for keeping this instrument under normal operation condition (once a week). Prepare a standard gas cylinder for zero calibration and span calibration.

3.4.4 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 the 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 or dry N

Action of peak alarm
(1) A peak count alarm is close at 5 times/hour. (ON)
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 logic 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.

7.4 Cleaning of sampling cell
Entry of dust or water drops in the sampling 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.
Caution
Maintenance actions should only be accomplished by properly trained and qualified personel.
Not withstanding these maintenance steps, local facility and organizational safety program requrirements must be followed.
7.4.1 Disassembly and assembly of sampling cell
There are two kinds of sampling cells, block cells (cell length: 4 mm, 8 mm, 16 mm, 32 mm) and pipe cells (Cell length: 64 mm, 125 mm, 200 mm and 250 mm).
2-component analyzer may incorporate both sampling cells in one optical unit. In such a case, detach the pipe cell and then block cell (See Fig. 7-3).
a. How to remove pipe cell (See Fig. 7-1)
1) Stop measured gas. If it is harmful, purge the pipe cell thoroughly with zero gas.
2) Turn OFF the power switch.
3) Remove the cover (with loose 6 screws on the front panel and a screw on the rear panel).
4) Remove the tube connected to the pipe cell.
5) Loosen and remove a screw (No. 7) from the cell retainer (No. 11) fastening the pipe cell
(bothends).
6) Remove the cell from the measuring unit and unscrew the infrared transmission window (No.
14) at both ends in the right direction.
7) For assembly, reverse the disassembly procedure and make sure to put the space in 0.5mm between light source unit and measuring cell and detector.
In addition screw the pipe part of gas inlet (No. 14) with window on the both side to the measuring cell with matching the pipe part and marked part of measuring cell.

5) Disconnect and remove detector output cables from detector output circuit board (No.12).
Applying identification mark on top of removed cable connector will ensure proper pin assignment later.
6) Unscrew the two screws (No. 10) that hold the detector to the light source unit to remove the detector from the measuring unit. The block cell can be removed together with the detector.
7) To remove the block cell, unscrew the two screws (No. 6) holding the block cell to the detector. The infrared transmission window (No. 8) 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 (No. 9) is placed between the window holder and block 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 cable connector into the PCB, be careful to attach the connector with proper pin assignment (top/bottom).

7.4.2 How to clean sampling cell
1) To clean the sampling cell inside or infrared ray transmission window, first clear large dirt of it with a soft brush and then wipe lightly with soft cloth.
Do not use abrasive or paper 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 sampling cell interior is very dirty, use a soft lint-free 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 the sampling cell or window cleaning is completed, assemble according to the sampling cell disassembly and assembly procedures. Assemble the pipe carefully. If it becomes bent or damaged, replace it with a new part.
5) Do not wash the sample cell components with water.

When error No.1 occurs, remove the top cover of the analyzer and check the LED on the light source power board. If LED light is turned off, this has been caused by disconnection of the light source.
When errors No. 1 to No. 3 and No. 10 occurs, the analyzer is faulty. Contact your dealer or our sales office.
When errors No. 4 to No. 8 occurs, the calibration procedure may be incorrect.
Check the following items, and if error still occurs, contact us as shown above.
(1) Is the calibration gas supplied in the analyzer?
(2) Does the calibration operation match the supplied gas? (For example, zero calibration is performed while flowing the span gas.)
(3) Does the supplied gas concentration match the gas concentration set at the calibration concentration setting?
Also, when errors No. 5 and No. 7 occurs, you can perform calibration forcibly, following the procedure shown below. Use it as fault recovery when calibration fails and calibration contents are missed.

2. Standard Functions output signal holding:
Output signals are held unchanged during manual and auto calibrations by activation of holding (turning “ON” its setting).
The values held are those just before start calibration mode or setting value.
Usage is selectable.
Indication of instantaneous values will not be held.
Switch ranges: The switch ranges function is available in manual, auto, and remote modes. Only preset switch method is effective.
Manual: Allows range to switch by key operation.
Auto: Automatically switched from first range to second range when the measured value exceeds 90%FS of first range.
Automatically switched from second range
Remote: Voltage contact input
(Option) to first range when the measured value drops to 80% or less first range.
Allows range to switch via an external signal when remote range switch input is received.
When the contact input terminals for each component are input voltage, the first range is selected, and it is switched to the second range when the terminals are open.
* These switch range value are settable between the first range and second range values (low/high range values).
3. optional Functions
Remote output holding:
Output signal is held at the last value or preset value by voltage input to the remote output holding input terminals.
Holding is maintained while is voltage input to the terminals. Indication of instantaneous values are not held.
Range identification signal:
The present measuring range is identified by a contact position.
The contact output terminals close for each component when the first range is selected, and open when the second range is selected.
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 900 seconds (in increments of 1 second)
Auto calibration remote start:
Auto calibration starts by opening the auto calibration remote start input terminal after short circuiting for 1.5 sec or longer.
Auto calibration starts when contacts open.
Auto zero calibration:
Auto zero calibration is carried out periodically at the preset cycle.
This cycle is independent from “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 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 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 within 60 to 900 seconds (in increments of 1 second)
High/low limit alarm:
Alarm contact output turns on when measurement value reaches the preset high or low limit alarm value.
Contacts close when the instantaneous value of each channel exceeds the high alarm limit value or falls below the low alarm limit value.
Instrument error contact output:
Contacts turn on at occurrence of analyzer error No. 1, 2, 3 or 10.
Calibration error contact output:
Contacts turn on at occurrence of manual or auto calibration error (any of errors No.
4 to 9).
Auto calibration status contact outputs:
Contacts turn on during auto calibration.

Moving average method is used. Sampling interval is 30 secs.
(Output is updated every 30 seconds.
Update is the averaged value of the most recently elapsed averaging time period.)
Averaging time period is settable within 1 to 59 minutes (in increments of 1 minute) or 1 to 4 hours (in increments of 1 hour).
Average value resetting:
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 sec or longer.
Output is reset by input voltage and restarted by opening the terminal circuit.

Response interval may be changed depending on timing of the switching gas by sample switching operation. (Td=5-20 seconds)
Interference from other gases:
Sample switching design effectively minimizes interference. But it may occur depending on component gas and its concentration.
Preprocessing can further decrease influence in this case.
