OVERVIEW> OVERVIEW This product measures the concentration of NO, SO2, CO2, CO and CH4 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 O2 sensor, it allows measuring up to 4 components simultaneously by using the built-in O2 sensor (up to 3 components if O2 measurement is excluded). Furthermore, use of a microprocessor and large sized liquid crystal display realizes improvement of operability, accuracy and multi- functions. This product is being purposely designed to be a part of large-scale fixed installations (LSFI.) Intended uses of the product being part of LSFI are • Combustion gas measuring / control of industrial furnaces / incinerators. • Steel gas analysis (blast furnace, converter, thermal treatment furnace, sintering ((pellet equipment)), coke furnace) • Chemical analysis (petroleum refinery plant, petrochemical plant, gas generation plant) • Environmental management and others IM 11G02Q01-01EN 3rd Edition : May 31, 2017-00  1.1 1-2 <1.

The water concentration should be equalized in reference gas and sample gas. *2: Use No2/NO converter in case of measuring NOx. *3: The concentration of measuring component in a reference gas determines whether a reference gas purifier is required or not. If the concentration level is lower than 0.1 % FS, a reference gas purifier is not required. If atmospheric air is used as reference gas and the measuring range is lower level than the description below, the use of a reference gas purifier is recommended. However, for measuring CO2, atmospheric air should not be used as reference gas. NO analyzer : 0-100 ppm or less, SO2 analyzer : 0-50 ppm or less, CO analyzer : 0-1000 ppm or less.

INSTALLATION> To install the analyzer for optimum performance, select a location that meets the following conditions; • IR250 is system built-in type, embedded in a steel rack, or enclosure of steel sheet. Keep a minimum clearance of 10 cm above the analyzer for heat dissipation. The same size of clearance is required for each analyzer when you install several units on a multistage rack. • Circuit breaker rating should meet the analyzer rating, that meets IEC60947-1 and IEC60947-3. • Circuit breaker should be installed near the analyzer where an operator can access it. • A label that clearly identifies the breaker should be placed on it. 3.2 How to install The next table shows the type of mounting and its code of equipment. Rack-mounting type of equipment can be installed with sliding rails. Mounting type (Code) IR250-A Rack-mounting with sliding rails (-A) Panel-mounting (-B) Wall-mounting (-C) Rack-mounting (-D)  See “2.4 IR250-B IR250-C IR250-D     External dimensions” on page 2-14. Follow the next instruction and install equipment properly. • Front side of equipment must stand vertically. • The analyzer weight must be supported at the bottom of the casing.(except IR250-B) • Protect the analyzer from vibrating. For example, install rubber material around the case to minimize the vibration. IM 11G02Q01-01EN 3rd Edition : May 31, 2017-00  3.3 3-3 <3. INSTALLATION> Piping WARNING 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. CAUTION Piping connection must be secured. Gas inlets have several types: reference gas inlet, outlet or purge gas inlet. When the connection is insecure or wrong, combustible, toxic, explosive gas may be accumulated inside the analyzer or system. Observe the following when connecting the gas pipes. • The pipes should be connected to the gas inlet and outlet on the analyzer, respectively. • Connect the sampling system to the instrument by using corrosion-resistant tube. The material should be such as Fluoropolymer (PTFE), 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 obtaining quick response. Pipe of approx. ∅4 mm (inside diameter) is recommended. • Entry of dust in the instrument may cause operation fault. Use clean pipes and couplings.

The gas flow rate should be kept constant within the range of 1.0 ± 0.5 L/min. for IR250-A, 0.5 ± 0.2 L/min. for IR250-B,IR250-D, and 1.0 ± 0.2 L/min. for IR250-C. Sampling gas (reference gas ) outlet: Measured gas is exhausted after measurement. Connect the pipe so that the gas may escape through the gas outlet into the atmosphere. Purge gas inlet: It is used for purging the inside of the total gas analyzer. When the analyzer must be purged, refer to Item 3.4, Purging inside Analyzer. Use dry gas N2 or instrumentation air for purge gas. (flow rate of 1 L/min or more should be used and no dust or mist is contained). Reference gas inlet: For IR250-C, introduce reference gas for the sample switching. Connect the pipe so that atmosphere pretreated with dehumidification, dry air, dry N2 is supplied properly. The gas flow rate should be kept constant within the range of 1.0 ± 0.2 L/min. IM 11G02Q01-01EN 3rd Edition : May 31, 2017-00  3.4 3-5 <3. INSTALLATION> Sampling See “1.2 Sampling system configuration” on page 1-3 l Standard requirements of sampling gas Flow rate: IR250-A ; 1.0 ± 0.5 L/min IR250-B, IR250-D ;0.5 ± 0.2 L/min IR250-C; 1.0 ± 0.2 L/min Temperature: 0 to 50°C Pressure: less than 10 kPa (atmosphere open at gas outlet) Dust : Particle size should be smaller than 0.3µm and the mass concentration should be less than 100µg / Nm3. Mist : Not allowed Moisture lower than 2°C saturation Corrosive element : less than 1 ppm Use sampling gas with care as below; • The dust contained in sample gas should be eliminated completely with filters. The filter at the final stage should be capable of eliminating dust of 0.3 microns. • The dew point of sample gas must be lower than the ambient temperature for preventing formation of drain in the analyzer. If water vapor is contained in sample gas, its dew point should be reduced down to about 0°C through a dehumidifier. • If SO3 mist is contained in sample gas, the mist should be eliminated with a mist filter, cooler, etc. Eliminate other mist in the same way. • If a large amount of highly corrosive gas such as Cl2, F2 or HCl is contained in sample gas, the service life of analyzer will be shortened. So, avoid such gases. • Sample gas temperature is allowed within a range from 0 to 50°C. Pay attention not to flow hot gas directly into the analyzer. • Flow rate must not be changed during a measurement. • Install a flowmeter as shown in a configuration (1.2), and check the flow rate. l Standard gas for calibration Prepare the standard gas for zero / span calibration. Periodical calibration are necessary. (weekly is recommended) Measuring components excluding O2 Zero gas: N2 gas Span gas: Gas with concentration of 90% level or higher in the range of each corresponding component (recommended) (the rest of it is N2) Measuring O2 (Built-in paramagnetic O2 analyzer) N2 gas Zero gas: Span gas: Gas with concentration of 90% level or higher in the range of each corresponding component (the rest of it is N2 gas or atmosphere (21% O2 )) IM 11G02Q01-01EN 3rd Edition : May 31, 2017-00  3-6 <3. INSTALLATION> Measuring O2 (External Zirconia O2 analyzer) Zero gas Dry air, or atmospheric air, but atmospheric air should not be contained in zero gas if CO2 meter is provided. Span gas 1 to 2% gas (the rest of it is N2) It is understood to influence the calibration model of the infrared gas analyzer when a lot of H2, He, and Ar are included in the measurement gas (pressure broadening). The span gas must use a gas near the composition of the measurement gas when you measure the gas like the above-mentioned. l Purging of instrument inside The inside of instrument need not be purged generally except for the following cases. • A combustible gas component is contained in sample gas. • Corrosive gas is contained in the atmospheric air at the installation site. • 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 N2. Purging flow rate should be about 1 L/min. If dust or mist is contained in purging gas, it should be eliminated completely in advance. l Pressure at sampling gas outlet Pressure at the sampling gas outlet should be adjusted to atmospheric pressure.

If using the instrument near such a noise generating unit is unavoidable, use a different power line to avoid noise • Mount a noise suppressor such as varistor or spark quencher as shown below to the noise generating unit when noise is generated from relays or solenoid valves. Mount the suppressor near the noise generating source, otherwise it will have no effect. Main unit power supply varistor or spark quencher install near the source Noise generating source n I/O Wiring Diagram NOTE • The analog output signals of the instrument are not isolated individually. It is recommended to isolate the signals individually to eliminate the interference from the unnecessary signals or the effect of external interference, especially it the cable exceeds 30 meters or leads to outdoors. • To avoid external interference, wiring of analog output signal, O2 sensor input and contact input should be run separately from that of power supply and contact output. • To avoid the effect of noise generated from external units, be sure to ground the analyzer main unit.

MAINTENANCE> 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 Service personnel from YOKOGAWA will take care of the maintenance. Contact YOKOGAWA representatives for maintenance service. 7.3.1 Disassembly and assembly of sampling cell (Pipe cell, Block 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 unit. In such a case, detach the pipe cell and then block cell CAUTION Special care should be taken when assembling or disassembling the measuring cell to avoid the application of force to the detector pipe or light source unit pipe. If the pipe is deformed or damaged by excessive force, there is a danger of gas leak, thus resulting in faulty operation. l How to remove pipe cell (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 screws then remove the cover.(Open the front door on IR250-B). (4) Remove the tubes connected to the pipe cell. (5) See Figure. 7.1. Loosen and remove screws (Screw A) from the cell retainer fastening the pipe cell (both ends). (6) Remove the cell from the measuring unit and unscrew the infrared transmission window at both ends in the right direction.Don’t miss the O-ring. (7) For assembly, reverse the disassembly procedure.Make sure to put the space in 0.5mm between light source unit and the pipe cell, the pipecell and the detector.

MAINTENANCE> How to clean sampling cell CAUTION Handle the fragile window with care. Use care not to rub off the dirt from the window roughly. • 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. • If the window or the sampling cell interior is very dirty, use a soft lint-free cloth moistened with absolute alcohol. • 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. • 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. • Do not wash the sample cell components with water.

Error No.2 Detector failure. • Detector voltage circuit is faulty. • Detector element is broken or faulty. • Amplifier circuit is faulty Error No.3 A/D error • A/D conversion circuit is faulty. Error No.4 Zero calibration is not within the allowable range. Error No.5 A amount of zero calibration (indication value) is over 50% of full scale. • Zero gas is not supplied. • Zero point is deflected much due to dirty cell. • Detector is faulty. Error No.6 Span calibration is not within the allowable range. Error No.7 A amount of span calibration (difference between indication value and calibrated concentration) is over 50% of full scale. Error No.8 Measured values fluctuate too much during zero and span calibration. • Calibration gas is not supplied. • Time for supplying calibration gas is short. Error No.9 Calibration is abnormal during auto calibration. • Error corresponding to No. 4 to No. 8 occurred during auto calibration. Error No.10 Output cable connection is improper. • DIO circuit is failure. • Internal wiring to the DIO circuit is broken. • Gas is not supplied long enough. • Span gas is not supplied. • Calibrated concentration setting does not match cylinder concentration. • Zero calibration is not performed properly. • Span is deflected much due to dirty cell. • Detector sensitivity is deteriorated. When one of those errors among No.1 to No.3 or No.10 occurs, instrument error (FAULT) contact output is closed. When one of those errors among No.4 to No.9 occurs, calibration error contact output is closed. n Trouble shooting When Error No. 1 occurs, remove the top cover of the analyzer and check the LED on the light source power PCB. If the LCD light is turned off, light source is disconnected. When Error NO.1 to No.3 or No.10 occurs, the analyzer is faulty. Contact us immediately. When Error No.4 to No.8 occurs, the calibration procedure may be wrong. Check the following again. If the error is still indicated, contact us immediately. • Is the calibration gas supplied in the analyzer? • Does the calibration operation match the supplied gas? (For example, zero calibration is performed while flowing the span gas by mistake.) • Does the supplied gas concentration match the gas concentration set at the calibration concentration setting?[ Also, when Error No.5 or NO.7 occurs, you can perform calibration forcibly by following the procedure described in the next section. Use it as fault recovery when calibration fails and calibration contents are missed.
