The cautionary descriptions listed here contain important information about safety, so they should always be observed. Those safety precautions are ranked in 2 levels, “DANGER” and “CAUTION.” DANGER CAUTION Wrong handling may cause a dangerous situation, in which there is a risk of death or heavy injury. Wrong handling may invite a dangerous situation, in which there is a possibility of medium-level trouble or slight injury or only physical damage is predictable. Caution on installation and transport of gas analyzer 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 • Install the gas analyzer in a place that satisfies the conditions described in the “Instruction Manual.” Otherwise electric shock, fire, or malfunction may result. • During maintenance and check, care should be taken to keep the unit free from cable chips or other foreign objects. Otherwise, it may cause fire, trouble or malfunction of the unit. • For lifting the gas analyzer, be sure to wear protective gloves. Bare hands may invite an injury. • The gas analyzer is heavy. Two or more persons should carry the gas analyzer with sufficient care to avoid injury or damage to body. iv INZ-TN514401-E Caution on piping DANGER 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 indoors. • Exhaust from the gas analyzer should be relieved in the atmospheric air in order that an unnecessary pressure will not be applied to the gas analyzer. Otherwise, any pipe in the gas 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 on wiring CAUTION • Be sure to perform specified grounding work to avoid electric shock or malfunction. • Be sure to use a power supply of correct rating. Connection of power supply of incorrect rating may cause fire. • Wiring work must be performed with the main power set to OFF to prevent electric shocks. • 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. Caution on use DANGER • For correct handling of calibration gas or other reference gases, carefully read their instruction manuals beforehand. CAUTION • Do not operate the gas analyzer continuously with the cover opened. Otherwise dust may enter, causing a failure. • Do not open the cover and touch inside while the gas analyzer is operated. Otherwise burns or electric shock may result. INZ-TN514401-E v Caution on maintenance and check DANGER • Before performing work with the cover opened, be sure to turn off the power and purge fully not only the gas analyzer but also measurement gas lines with air and N2 gas. Be careful not to stain the filter and packing with oil or grease. Otherwise gas leak may occur, thus causing poisoning, fire, or explosion. CAUTION • Be sure to remove metallic objects such as a wristwatch or a ring. Never perform work with wet hands to avoid electric shock. • If the fuse is blown, eliminate the cause, and then replace it with the one of the same capacity and type as before. Otherwise, shock hazard or fault may be caused. Others CAUTION • If the cause of any fault cannot be determined despite reference to the instruction manual, be sure to contact your dealer or Fuji Electric’s technician in charge of adjustment. If the instrument is disassembled carelessly, you may have a shock hazard or injury. • Do not use replacement parts not specified by the manufacturer. Otherwise sufficient performance of the gas analyzer may not be obtained, or accidents or failure may result. • Dispose the parts removed for maintenance as noncombustible waste. vi INZ-TN514401-E 1.

Also check that the zero gas pot is filled with clear water. (ZSVF) → Locate a gas leaked portion and remedy. 2) Check if detector signal is as specified (based on result of detector signal checked on amplifier printed circuit board). → Adjust detector signals. If a check cannot be made on signals, check the detector. Record voltage when zero gas is supplied and check the detector voltage. 3) Check the A/D data against the display (see Factory mode and A/D data). → Check voltage at the main printed circuit board. Check the switching power supply. Record the A/D data when zero gas is supplied. (2) No span calibration can be performed 1) Check that span gas concentration and span concentration settings are the same. 2) Check that specified amount of span gas is supplied to the gas analyzer main unit. → Locate a gas leaked portion and remedy. 3) Check that zero calibration can be properly performed. → If zero calibration can not be performed, repeat the procedure “1) No zero calibration can be performed.” 4) Check if detector signal is as specified (based on result of detector signal checked on amplifier printed circuit board). → Record voltage when span gas is supplied (to compare with the voltage when zero gas is supplied). Check the detector and detector voltage. 5) Check the A/D data against the display (see Factory mode and A/D data). → Check voltage at the main printed circuit board. Check the switching power supply. Record the A/D data when span gas is supplied. (3) Drift 1) Check that specified amount of measured gas is supplied to the gas analyzer main unit. → Locate a gas leaked portion and remedy. 2) Check that the cell window, O-ring, detector window and cell inside are not contaminated. → Clean the cell and window. Replace parts. (4) Readings are high or low too much. 1) Check that a large quantity of interference components (moisture) is not contained in sampling gas. → Check the components of the measured gas. (Check it with the user.) 48 INZ-TN514401-E (5) Readings are not increased 1) Check that specified amount of measured gases are supplied to the gas analyzer main unit. → Locate a gas leaked portion and remedy. 2) Check that zero and span calibration can be performed. → If possible, check for sampling gas (related to measured gas) and take remedies. → If not possible, check the procedure (1) and (2). INZ-TN514401-E 49 6. ADJUSTMENT IN HEAT TREATMENT FURNACE ● What is the adjustment in heat treatment furnaces? If, in plant gases to be measured actually, a large amount of other lower-molecular-weigh gases than nitrogen (N2) such as hydrogen (H2), or a large amount of other higher-molecular-weight gases than nitrogen (N2) such as argon (Ar) are contained, including the measuring components, it is known that the calibration curve (output performance to gas concentration) of the gas analyzers will be affected (pressure broadening). In such a case, the gas analyzer is adjusted with gases similar to plant gas compositions in manufacturing (adjustment by scale gas). After this adjustment, the gas analyzer is checked the calibration curve with N2 balance gas (calibration curve by check gas). Graphs with these calibration curves drawn are attached to products to be supplied. Since measurement in a heat treatment furnace has much gas of such composition, adjustment in heat treatment furnaces is performed. In order to perform exact measurement, there are two methods in span calibration: Composition of the standard gas for span calibration used for each method and its method are explained using an example. For the standard gas for zero calibration, use N2 or Air in any case so that zero point will not be affected. <Example> Assume that a 0 to 1% CO2 meter of the infrared gas analyzer measures CO2 contained in plant gases. When plant gases are composed of 0.5% CO2, 25% CO, 30% H2, 0.2% CH4 and 44.3% N2, either of the following is used as the span calibration standard gas. Standard gas type 1 Standard gas with the same composition as plant gases (scale gas) 2 Check gas Composition of standard gas 0.9% to 1% CO2 25% CO, 30% H2, remainder is N2 * 0.9% to 1% CO Remainder is N2. Method for span adjustment Perform span calibration directly. Perform span calibration indirectly. * A gas in small amount that has little effect on span calibration such as 0.2%CH4 is not included. (1) Method for span calibration by standard gas with the same composition as plant gas When using the standard gas with the same composition as plant gases given in 1, calibration can be performed without correction, as an error in calibration curve does not occur. 1) Set CO2 concentration to span calibration concentration set value. 2) Perform span calibration by using the operation key. 50 INZ-TN514401-E (2) Method for span calibration by check gas Span calibration is performed as follows when two kinds of check gas are used. (Since span calibration has an error of calibration curve, preset a calibration indication on the calibration curve graph attached to this gas analyzer for indirect calibration.) 1) The following calibration curve graph is attached to the test results for the product. In graph, the calibration curve by the scale gas (that is similar to plant gas and determines scales of this gas analyzer) and the calibration curve by the check gas that is adjusted by the scale gas (gas of simple composition of N2 balance gas to facilitate the gas analyzer check) are drawn. 1.0V Calibration curve by scale gas (composition of plant gases) 0.9 0.89V 0.8 Calibration curve by check gas (N2 balance gas) * When supplying check gases to instruments adjusted by the scale gas composition. 0.7 Output 0.6 0.5 0.4 0.3 0.2 0.1 0 0 0.1 0.2 0.3 0.4 0.5 0.6 Measuring gas concentration 0.7 0.8 0.89%CO2 0.9 1%CO2 0.95%CO2 Calibration curve graph attached to the product 2) When using 0.95% CO2 and remainder N2 (check gas) as calibration gas, in graph, a point of 0.95% on X-axis should be stretched to upward, draw a line toward Y-axis from the cross point with the check gas calibration curve. From the cross point with calibration curve on the scale gas composition, 0.89% or equivalent values can be obtained. 3) Set this point (0.89%) to the span calibration concentration of the calibration concentration set value. 4) Supply 0.95% check gas to perform span calibration. Then, the concentration value is corrected to 0.89%. Measurement suited to actual plants can be performed by this error correction of calibration curve. INZ-TN514401-E 51 7.
