Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 4. THE M200AH NOX ANALYZER 4.1. Principle of Operation 4.1.1. NOX Measurement The Teledyne API Model 200AH Analyzer is designed to measure the concentration of nitric oxide [NO], total oxides of nitrogen [NOx] and, by calculation, nitrogen dioxide [NO2] (Note: the calculation of NO2 is not available in instruments equipped with the Oxygen measurement option.) With the proper setup, it can operate in any of three sampling modes.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 concentration is measured and stored internally. The valve is then switched, routing the sample gas through the converter, the signal measured is the NOX concentration which is also stored in the computer. The [NO2] component is calculated by subtracting [NOX] - [NO] = [NO2] using the built-in computer.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 Figure 4-1: Paramagnetic Sensor Refer to Figure 4-1. The measuring system is “null-balanced”. First, the ‘zero’ position of the suspension assembly, as measured in nitrogen. is sensed by a split photo-sensor that receives light reflected from a mirror attached to the suspension assembly. The output from the photosensor is fed back to a coil wound around the suspension assembly.

Test Functions NOTE In any of the following TEST functions, if a value of XXXX is displayed, that indicates an off scale and therefore meaningless reading. TEST functions allow the operator to examine several important operating parameters of the M200AH to verify correct Analyzer operation. If faults are discovered, refer to Troubleshooting Section 9. Range (RANGE) This is the Range of the instrument.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 Signal Stability (STABIL, NOX STB) The instrument noise is computed by calculating the standard deviation of the last 10 minutes of concentration data. If NO/ NOX switching mode is selected, the noise reading is that of the NOX channel. If NO only or NOX only mode is selected the Noise applies to the mode selected. The noise value only becomes meaningful if sampling a constant concentration for more than 10 minutes.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 DC Power Supply Voltage (DCPS) The DCPS voltage is a composite of the 5 and 15 VDC voltages in the Power Supply Module. This is meant to be a quick indicator to show if the PSM is working correctly. The nominal value is 2500 mV 200 mV. Reaction Cell Temperature (RCEL TEMP) This is a measurement of the temperature of the reaction cell. It is controlled by the computer to 50 2C.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 If the analyzer is equipped with the molybdenum converter option the TEST function will report MOLY TEMP, the temperature setpoint will be 315 10°C. If the analyzer is equipped with the Model 501 external converter option, the converter temperature is shown on the front panel of the M501. The TEST function O3KL will report the temperature of the catalytic ozone killer located inside the converter can.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 5.2.2. CAL, CALS, CALZ, Calibration Functions The calibration and zero/span checking of the M200AH analyzer is treated in detail in Section 7, Table 7-1 summarizes types of calibration. 5.2.2.1. CAL, CALS, CALZ The CAL, CALS, and CALZ keys control the calibration functions of the analyzer. In the CAL mode the analyzer can be calibrated with zero/span gas coming in through the sample input port on the rear panel.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 5.2.2.5. NO, NOX and O2 Cal Concentration Before the M200AH can be spanned, it is necessary to enter the expected span concentrations for NO and NOX. In single range mode there is one value each for the NO, NOX and O2 expected span values. The span values are entered by pressing CAL-CONC-NO or CAL-CONC-NOX or CAL-O2-CONC keys for NO , NOX and O2 span concentrations respectively.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 Because the span calibration calculation includes zero calibration data and zero calibration includes span calibration data, the zero and span calibrations can be performed in any order and the instrument will be accurately calibrated either way. After every zero or span calibration, it is very important to check the QUALITY of the calibration.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 5.3.3. Data Acquisition System (DAS) The M200A contains a flexible and powerful built in data acquisition system (DAS) that enables the analyzer to store concentration data as well as diagnostic parameters in its battery backed memory. This information can be viewed from the front panel or printed out through the RS-232 port.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 The function of each of the default Data Channels is described below: CONC: Samples NOX, NO and NO2 (NOX, NO and O2 if the instrument is equipped with the Oxygen option) concentration data at one minute intervals and stores an average every hour with a time and date stamp. Readings during calibration and calibration hold off are not included in the data. The last 800 hourly averages are stored.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 5.3.4. Range Menu For NOX measurements, the instrument operates on any full scale range from 5 to 5,000 ppm. The range is the concentration value that equals the maximum voltage or current output on the rear panel of the instrument. If the range you select is between 5 and 500 ppm the front panel will read the concentration anywhere from 0 to 500 ppm regardless of the range selected.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 To set up Auto Range press SETUP-RNGE-MODE-AUTO, then press ENTR. To set the values press SETUP-RNGE-SET. The M200AH will prompt you for LO, then HI which is the lower and upper ranges of Auto Range. Key in the value desired, then press ENTR. Remote Range works the same as AutoRange except that the LO/HI range decision is made via remote status inputs on the rear panel, see Figure 2-2 for pinout.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 3. SELECT RANGE The range selection is the same with dilution as with normal monitoring. See Section 5.3.4 for information on range selection. You should note however, the value entered should be the actual concentration of the calibration gas entering the dilution probe. The units of this number is ppm. 4. CALIBRATION When the above selections have been made, the instrument now must be calibrated through the dilution probe.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 5.3.4.7. Recorder Offset If necessary, a recorder offset can be introduced into the analog output voltages. This can be used to bias the output voltage or current 10%. It is intended for older design chart recorders that cannot show slightly negative readings. It can also be used to bias the input to a datalogger to offset small external ground loop voltages that are sometimes present in monitoring systems.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 5.3.8. Communications Menu The COMM menu allows the RS-232 BAUD rate to be set. To set the BAUD rate press SETUPMORE-COMM-BAUD, select the appropriate BAUD rate, then press ENTR. The instrument ID number can also be set. This ID number is attached to every RS-232 message sent by the M200AH. To set the ID press SETUP-MORE-COMM-ID and enter a 4 digit number from 0000-9999, then press ENTR.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 5.4. M200AH Operating Modes The M200AH has two main operating modes. The instrument is normally in SAMPLE mode when it is taking data or doing a calibration. The second main mode is the SETUP mode. In this mode the many features of the instrument can be altered, enabled or disabled. Within these two main modes there are many other operating modes which are shown in Table 5-7.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 This is the most common mode of operation. It provides continuous output of NO, NOX and NO2 gas concentrations. To select switching mode press SETUP-MORE-VARS-ENTR and press NEXT to scroll to the MEASURE-MODE variable. Set the value of this variable to NO NOX, then press ENTR. Press EXIT to return to SAMPLE mode. 5.4.2. NOX Only Mode In this mode only NOX is measured. The converter is in the sample stream continuously.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 5.5. 4-20 mA Current Loop The analog signal output is available on the rear panel as a voltage or 4-20 mA current output. Optionally the current loop outputs can be isolated. See Section 6.3 for a description of isolated current loop outputs. The current outputs come out on the same terminals that are used for voltage outputs see Figure 2-2. The NO, NOx, NO2 and Test Channel outputs have current loop capabilities.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 5.7. RS-232 Interface The RS-232 communications protocol allows the instrument to be connected to a wide variety of computer based equipment. The interface provides two basic functions in the M200AH. 1. First is a comprehensive command interface for operating and diagnosing the analyzer. The command set can be used interactively or operated via stored program.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 940331 is the default password. The password can be changed to any number from 0 to 999999 by the variable RS232_PASS. To change the password enter the command V RS232_PASS=940331 which sets the password to the factory default. Protocol of Port Communication The RS-232 interface has two protocols of communication, because if the port is attached to a computer it needs to have different characteristics than if used interactively.

Examples of the T command are: T LIST Lists test messages currently enabled with T SET T LIST ALL Lists all test messages T CONVTEMP Prints the temperature of the converter T LIST NOX Prints NOx concentration message T NOX Prints concentration message 5.7.4.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 Whenever a warning message is reported on the analyzer display, if the RS-232 interface is in the normal mode(i.e. not in quiet mode) the warning message is also sent to the RS-232 interface. These messages are helpful when trying to track down a problem with the analyzer and for determining whether or not the DAS reports are actually valid.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 Whenever the analyzer starts or finishes a calibration, it issues a status report to the RS-232 interface. If the RS-232 interface is in the normal mode, these reports will be sent. Otherwise, they will be discarded.

Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 9.2. Performance Problems When the response from a span check is outside the control limits, the cause for the drift should be determined, and corrective action should be taken. Some of the causes for drift are listed below: NOTE It has been our experience that about 50% of all analyzer performance problems are sooner or later traced to leaks in some part of the system. 1. Fluctuations in flow, caused by leaks or plugged orifices. 2.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 9.2.2. Flow Check 1. Check TEST function RCEL - this is the absolute pressure in the reaction cell. It should be 3 - 10 in-Hg-A. 2. Check that pump is running. Observe pump for proper operation. 3. Check that pump tubing is connected to rear of analyzer. 4. Confirm that the sample pump is producing vacuum by removing fitting at rear of analyzer and checking for suction at fitting. 5. Check for correct flows.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 2. Check instrument electronics. A. Do ELEC TEST procedure in DIAGNOSTIC menu Section 9.1.3.2. B. Do OPTIC TEST procedure in the DIAGNOSTIC menu Section 9.1.3.3. If the M200AH passes ET and OT that means the instrument is capable of detecting light and processing the signal to produce a reading. Therefore the problem is in the pneumatics. 3. Check ozone generator subsystem.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 3. HVPS noisy - see HVPS test procedure. See Section 9.3.8.5. 4. Defective electronic components on preamp board. - use optic test and electric test to check electronics, optics and observe noise. 5. Contamination of ozone generator and/or reaction cell - This can be wet air or impurities. This can be detected by high PMT readings with zero air as sample gas.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 9.2.7. Unstable Zero Common causes are: 1. Leak in pneumatic system. 2. Light leak - check the sensor module with strong light. 3. Sample lines or sample filter dirty - clean or replace. 9.2.8. Inability to Span If the SPAN button is not illuminated when attempting to span, that means the reading is outside of the software gain ranges allowed.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 A. A leak that admits gas containing NO. B. Contaminated reaction cell. Remove and clean cell. C. Wet (i.e. undried ambient air) air into the ozone generator. Check the PermaPure drier and associated plumbing for leaks and correct operation. D. Zero gas that isn't really zero. Make sure you're not trying to zero the machine with sample air or span gas. E. AutoZero filter is corrupted with high readings.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 7. Ozone concentration too low: A. Wet air in generator - need to disassemble, clean, dry. B. Electrical short circuit. C. Transformer partial failure. 8. Sample inlet vent line too short - should be at least 15". 9. Sample exhaust not properly vented, creating a backpressure at the sample inlet port of the instrument. See Figure 2-4 for venting recommendations. 9.2.11. Slow Response 1.

Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 Common faults in the ozone generator are: 1. A leak or some other failure in the drier will let ambient air into the generator. There is enough water vapor in room air to cause the generator to make nitric acid aerosol. It is very corrosive and causes the generator cartridge to short out, and plug up due to salt build-up.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 9.3.6.1. The PermaPure Drier The PermaPure drier is constructed of 2 concentric tubes. The inner tube is a special material that has an affinity for water vapor. The outer annulus is evacuated by the instrument pump. This creates a concentration gradient causing water in ambient air to diffuse into the outer annulus, thus the air in the inner tube becomes progressively drier as it progresses down the tube.

PMT The PMT detects the light emitted by the reaction of NO with ozone. It has a gain of about 500,000 to 1,000,000. Because of its high sensitivity to light, it is not possible to test the detector outside of the instrument in the field. The best way to determine if the PMT is working is by using Optic test.
Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2 9.3.8.4. PMT Cooler The PMT cooler uses a Peltier cooler supplied with DC current from the switching power supply in the Power Supply Module. An overall view is shown in Figure 9-11. The temperature is controlled by a proportional temperature controller located on the Preamp board. The input voltage from the supply is 15 VDC. Typical current through the cooler at room temp is about 1.5 to 2 A.
