1. OVERVIEW The infrared gas analyzer (IR200) measures the concentrations of CO2, CO, CH4, SO2, NO and O2 contained in sample gas. CO2, CO, CH4, SO2, and NO are measured by non-dispersion infrared method, while O2 is measured by paramagnetic or fuel cell method. Up to 4 components including O2 (3 at the maximum for measurement of components other than O2) can be measured simultaneously. A high-sensitivity mass flow sensor is used in the detector unit of infrared method.
2. NAME AND DESCRIPTION OF EACH PART 2.
3. INSTALLATION DANGER This unit is not explosion-proof type. Do not use it in a place with explosive gases to prevent explosion, fire or other serious accidents. CAUTION • For installation, observe the rule on it given in the instruction manual and select a place where the weight of gas analyzer can be endured. Installation at an unsuited place may cause turnover or fall and there is a risk of injury. • For lifting the gas analyzer, be sure to wear protective gloves. Bare hands may invite an injury.
3.2 Installation of analyzer There are two methods of installing the analyzer. For detailed dimensions, see Chapter 9.3. (Unit:mm) 19 inch rack mounting (Note) Types External dimensions Mounting dimensions Mounting method Guide rail MODE ENT Slide rail M6 ZERO ESC SPAN 429 450 or more 483 465 101.
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.
(2) Sampling gas flow rate A flow rate of sampling gas must be 1 ± 0.5L/min. A flow meter should be provided as shown in Fig. 3-2 to measure flow rate values. (3) Preparation for standard gas Prepare the standard gas for zero/span calibration.
(7) Example of sampling system configuration The system configuration may vary depending upon the nature of measured gas, coexistent gases or application. A typical configuration diagram is shown in Fig. 3-2. Since a system configuration depends upon measured gas, consult with Yokogawa.
3.5 Wiring method Caution on wiring • Wiring work must be performed with the main power set to OFF to prevent electric shocks. CAUTION • Enforce construction of class-D grounding wire by all means, 100V or less. If the specified grounding construction is neglected, a shock hazard or fault may be caused. • Wires should be the proper one meeting the ratings of this instrument. If using a wire which cannot endure the ratings, a fire may occur. • Be sure to use a power supply of correct rating.
When noise source is in the vicinity Do not install the instrument near an electric device that generates noise from the power supply (such as high-frequency furnace and electric welder). If there is no other choice but to install it near such devices, provide completely separate power line to eliminate noise. In case noise may enter from a relay, solenoid valve, etc. through power supply, connect a varistor or spark killer to the noise source as shown below.
(4) Contact input (DI): terminal block 2, 13 to 20 , terminal block 3, 5 to 10 . • It is for a contact input at no voltage. An input is provided when switching to short circuit (on) or open (off). • No voltage is applied to the terminals. (5) Contact output (DO): terminal block 3, 13 to 20 , terminal block 4 and terminal block 5 • Contact rating: 250 V AC/2 A, load resistance • An output is for a relay contact output.

d Precautions to be taken while checking 1. When handling reference gas (during calibration), carefully read the reference-gas instruction manual to use the gas correcrtly. In particular, special attention must be taken in handling carbon monoxide gases; otherwise, you may suffer from gas poison-ing. 2. During maintenance checks, be sure to keep the near fan on.

Error display Error contents Probable causes Error No.1 Sector motor rotation detector signal is faulty. • Infrared ray light source is faulty. • Sector motor rotation is faulty or stopped. • Motor rotation detector circuit is faulty. • Amplifier circuit is faulty. Error No.3 A/D conversion signal is faulty. • Circuit is faulty. Error No.4 Zero calibration is not within the allowable range.
In case of Error No. 5 and No. 7 ENT ? Pressing ESC delete the error display. ENT ESC Calibration is continued. Unless another calibration error occurs, calibration is carried out to the end, the Measurement screen returns. Error log file If error occurs, the history is saved in an error log file. The error log file exists in the maintenance mode. Error log screen Day of the week and time when an error occurred. Component with which the error occurred.
8.2 Other Troubleshooting The following table shows how to remedy other troubles, such as faulty readings. Symptom Checking Item Remedy, etc. Drift * Check if the sample gas is supplied to the analyzer at the specified flow rate. * Check the optical system, e.g., the sample cell window, O-ring, detector window and inside of the cell for heavy dirt.

(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.
(3) Optional functions O2 correction: Conversion of measured CO , SO2 and NO gas concentrations into values at reference O2 concentration. 21-On Correction formula: C = –––––––– x Cs 21-Os C : Sample gas concentration after O 2 correction Cs : Measured concentration of sample gas Os : Measured O2 concentration O n : Standard O 2 concentration (value changeable by setting) *The upper limit value of the fractional part in this calculation is 4.
(6) Installation Requirements • Use this instrument .(Select a place where the equipment does not receive direct sunlight, draft/rain or radiation from hot substances.) • Avoid a place where receives heavy vibration. • Select a place where atmospheric air is clean.
