Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2

1. HOW TO USE THIS MANUAL

The Model 200AH has been designed to produce accurate data, be serviceable, reliable and easy to use. The M200AH's microprocessor continually checks operating parameters such as temperature, flow, and critical voltages. The instruments design uses top mounted, modular components with captive screws to facilitate repair and ease of access. If you encounter any difficulty refer to the Troubleshooting Section 9 - General Hints.

We recognize that the need for information from this manual changes as time passes. When the instrument first arrives, it is necessary to get it up and running quickly and verify its correct operation. As time passes, more detailed information is often required on special configurations, calibration alternatives and other operational details. Finally there is the need for periodic maintenance and to quickly troubleshoot problems to assure maximum reliability and data integrity.

To address these needs, we have created three indexes to the information inside. They are: Table of Contents: Outlines the contents of the manual in the order the information is presented. This is a good

overview of the topics covered in the manual. There is also a list of Tables and a list of Figures. Index to M200AH Front Panel Menus: The Menu Index briefly describes the front panel menus and refers you to other sections of the

manual that have a detailed explanation of each menu selection. Troubleshooting Section 9: The Troubleshooting Section allows you to diagnose and repair the instrument based on

variables in the TEST menu, the results of DIAGNOSTIC tests, and performance faults such as excessive noise or drift. The troubleshooting section also explains the operation, adjustment, diagnosis and testing of each instrument subsystem.

If you are unpacking the instrument for the first time, please refer to Getting Started in Section 2.

2. GETTING STARTED

2.1. Unpacking

CAUTION

Your safety and the safety of others is very important. We

have provided many important safety messages in this manual.

Please read these messages carefully.

To avoid personal injury, always use two persons to

lift and carry the Model 200AH.

1. Before operation it is necessary to remove the shipping hold-down screws. Remove the

instrument cover, then remove 2 screws as shown in Figure 2-1.

2. Also check for internal shipping damage, and generally inspect the interior of the instrument

to make sure all circuit boards and other components are in good shape.

3. Please check the voltage and frequency label on the serial number tag on the rear panel.

Compare that to your local power before plugging in the Instrument.

2.2. Electrical and Pneumatic Connections

1. Refer to Figure 2-2 to locate the rear panel electrical and pneumatic connections.

2. Attach the pump to the “Exhaust Out” port on the instrument rear panel. The exhaust from

the pump should also be vented to atmospheric pressure.

3. Attach the sample inlet line to the sample inlet port. For initial testing, sample gas can be

calibration gas or stack gas. The pressure of the sample gas at the inlet port should be at ambient pressure and constant. See Figure 2-4.

4. If desired, attach the analog output connections to a strip chart recorder and/or datalogger.

Refer to Figure 9-4 - Analog Output Voltage Ranges - for switch settings. Factory default setting is 0-5 VDC.

5. Connect the power cord to the correct voltage line, then turn to Section 2.3 Initial Operation.

2-1

Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2

WARNING

Analyzer Exhaust – O3 Scrubber – Pump Pack

Danger – Analyzer exhaust contains ozone.

Do not defeat the internal zone scrubber. This device must always

be present between the analyzer reaction cell and pump.

Vent pump exhaust to well ventilated area at atmospheric pressure.

FIRE or EXPLOSION HAZARD

If the optional charcoal NO2 scrubber is used on the exhaust,

charcoal treated with halogen compounds must not be used.

Use only Teledyne API P/N 00596 charcoal.

Wait at least 5 minutes after turning off pump before

removing NO2 scrubber.

WARNING

Lethal voltages present inside case.

Do not operate with cover off during normal operation.

Before operation check for correct

input voltage and frequency.

Do not operate without proper chassis grounding.

Do not defeat the ground wire on power plug. Turn off analyzer power before disconnecting

electrical subassemblies.

2.3. Initial Operation

1. Turn on the instrument power.

2. The display should immediately light, showing the computer’s memory configuration, then

the instrument type - M200AH. If you are unfamiliar with the M200AH, we recommend that you read the overview Section 4 before proceeding. A diagram of the software menu trees is in Figure 5-1 and Figure 5-2.

3. The M200AH requires about 30 minutes for all internal components to come to temperature.

During this time the ozone generator power is OFF until the membrane dryer has time to purge itself, therefore there will be no response from the instrument, even if span gas is coming in the sample port. Many warning conditions are not displayed during this time, even though temperatures and other conditions are out of specification. All warning messages are enabled after 30 minutes of operation.

4. While waiting for instrument temperatures to stabilize, you can check for correct operation

by using some of the M200AH's diagnostic and test features.

5. Examine the TEST functions by comparing the values listed in Table 2-1 to those in the

display. Remember that as the instrument warms up the values may not have reached their final values yet. If you would like to know more about the meaning and utility of each TEST function refer to Table 9-1. Also, now is a good time to verify that the instrument was shipped with the options you ordered. Table 2-1 also contains the list of options. Section 6 covers setting up the options.

6. Electric Test and Optic Test both generate simulated signals in the M200AH. A. Electric Test checks the electronics of the PMT signal path. To operate Electric Test from

the front panel:

1) Scroll the TEST function to PMT.

2) Press SETUP-MORE-DIAG, then press ENTR to accept the default password. Scroll

to Electric Test and press ENTR to turn it on. Instrument responses should come to the values indicated in Table 2-1. To turn off this test press EXIT. For more information on the circuitry being tested refer to the Troubleshooting Section 9.1.3.2.

B. Optic Test is an "end to end" test of the analyzer HVPS-PMT-detector-electronics-

computer. It simulates a signal by turning on a LED in the Sensor Module. To operate Optic Test from the front panel:

1) Scroll the TEST function to PMT.

2) Press SETUP-MORE-DIAG, then press ENTR to accept the default password. Scroll

to Optic Test and press ENTR to turn on optic test. Instrument response should come up to the values indicated in Table 2-1. To turn off this test press EXIT. To return to the SAMPLE mode press EXIT until SAMPLE is displayed in the upper left display. For more information about OT operation see Section 9.1.3.3.

2-7

Teledyne API Model 200AH NOX Analyzer Instruction Manual, 06492, Rev. G2

7. When the instrument is warmed up, re-check the TEST functions against Table 2-1. All of

the readings should compare closely with those in the table. If they do not see Section 9.1.1. The next task is to calibrate the analyzer. There are several ways to do a calibration, they are summarized in Table 7-1. For a preliminary checkout we recommend calibration with span gas coming in through the sample port. The procedure is:

Step 1 - Set the range, then enter the expected NOx, NO and O2 span gas concentrations:

Step

For Units w/o

O2 Option

1. Press

CAL-CONC-NOX

For Units with

O2 Option

Press CAL-NOX-ENTR CONC-NOX

2. Press ENTR Press ENTR

3. Press

CAL-CONC-NO

Press CAL-NOX-ENTR CONC-NO

4. Press ENTR Press ENTR

5. Press

CAL-O2-CONC

Comment

This key sequence causes the M200AH to prompt for the expected span concentration. Enter the span value by pressing the key under each digit until the expected value is set.
