<2. SPECIFICATIONS> Auto calibration starts by opening the auto-calibration-remote-start input terminals after short- circuiting them for 1.5 seconds or longer. Auto zero calibration: Auto zero calibration is carried out periodically at the preset cycle. This cycle is independent of “Auto calibration” cycle. When zero calibration gas and solenoid valve for opening/closing the calibration gas flow line are prepared externally by the customer, the zero calibration will be carried out at the preset auto zero calibration timing with the solenoid valve drive contact (for zero calibration) turned on/off.

(±2% of full scale/day for range less than 0-50 ppm) Response time (for 90%FS response) : Within 60 seconds including replacement time of sample gas (when gas flow rate is 0.5 L/min). Gas replacement time depends on the number of measuring components, and measuring range effects of interfering gases. Effects of interfering gases: When sample gas contains gas components listed below, the measurement accuracy may suffer. Consult Yokogawa for the countermeasures or the effect on accuracy. Analyzer Interference gas Effect analyzer 50 ppm of NO is equivalent to -6 ppm of SO...

SETTING AND CALIBRATION> <How to set/change the range> Select operating item The measuring range can be arbitrarily selected in the minimum and the maximum range specified at the time of purchase. The range to be used can be selected 1 or 2. Move the cursor to the item to be set by pressing or the key, and then press the key.
5-40 <5. SETTING AND CALIBRATION> 5.9 Calibration 5.9.1 Zero calibration ZERO It is used for zero point adjustment. For zero calibration, gas suited for an application should be used according to “(3) Standard gas in Item 3.3 Sampling.” Press the key on the Measurement ZERO screen to display the Manual Zero Calibration screen.
5-41 <5. SETTING AND CALIBRATION> 5.9.2 Span calibration It is used to perform a span point adjustment. Supply calibration gas with concentration set to the span value to perform the span calibration. For the span calibration gas for the NO , SO , CO , CO measurement, use the standard gas with a concentration of 90% or more of the range value.
6. MAINTENANCE WARNING Purge not only inside of IR400 but all measuring gas lines with zero gas sufficiently, when you provide maintenance or inspection on IR400 with its cover or door open. Otherwise it may cause hazardous accidents such as gas leakage, fire and explosion. CAUTION Do not operate the analyzer for a long time with its cover or door left open. Otherwise, dust,foreign matter, etc.

MAINTENANCE> 6.2 Daily check and maintenance procedures Table 7.1 Maintenance and check table Parts to be checked Phenomena Causes Remedy Indication value Indication values are (1) Clean the sampling cell. (1) Dust is mixed in lower. sampling cell In addition, check sampling Indication values are devices, especially gas filter. higher. (2) Air is absorbed midway (2) Find out cause of leak and in the sampling pipe.

<6.MAINTENANCE> After the end of sample cell cleaning, mount the cell in place and proceed to running. After cleaning sample cell, be sure to perform optical zero adjustment (see Item 6.3.3) and moisture interference compensation adjustment (see Item 6.3.4). WARNING If the window or the cell interior is very dirty, use a soft cloth moistened with absolute alcohol.
<6. MAINTENANCE> 6.3.2 Cleaning method for sample cell (block cell) (1) Turn off the power switch, stop the sample gas, and allow the zero gas to Top cover flow for several minutes to purge the cell interior. Loosen the setscrew (2 pieces) from the top cover and remove it. Remove the internal gas inlet tube. Loosen the 2 detector set bolts. Note) The distribution cell, block cell and detector are fastened by the same bolts.

<6. MAINTENANCE> 6.3.3 Optical zero adjustment method (optical balance adjustment) WARNING If the following operation is maladjusted, the measurement may adversely be affected. If you are not trained for adjustment, do not carry out this operation but contact the distributor or our serviceman.

<6.MAINTENANCE> Carry out the adjustment in the procedure in (4) and subsequent. ● Adjust on the primary side of the optical system so that the values for (a) to (d) in 1-1 and 1-2 become as close to 0 as possible within ±100 range. ● Adjust on the secondary side of the optical system so that the values for (e) to (h) in 2-1 and 2-2 become as close to 0 as possible within ±100 range. Operate the optical zero adjustment Optical zero adjustment knob knob to change the value displayed at (a) or (e).

<6.MAINTENANCE> 6.4 Inspection and maintenance of limited service-life components The analyzer uses limited-life components. The recommended replacement periods are listed in the below table. 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. The following table only involves the recommended periods for conducting preventive maintenance for limited service-life components;...
