SAFETY MESSAGES

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.

A safety message alerts you to potential hazards that could hurt you or others. Each safety

message is associated with a safety alert symbol. These symbols are found in the manual and

inside the instrument. The definition of these symbols is described below:

GENERAL WARNING/CAUTION: Refer to the instructions for details on the

specific danger.

CAUTION: Hot Surface Warning

CAUTION: Electrical Shock Hazard

Technician Symbol: All operations marked with this symbol are to be performed

by qualified maintenance personnel only.

Electrical Ground: This symbol inside the instrument marks the central safety

grounding point for the instrument.

CAUTION

The analyzer should only be used for the purpose

and in the manner described in this manual.

If you use the analyzer in a manner other than that for which

it was intended, unpredictable behavior could ensue with

possible hazardous consequences.

1 HOW TO USE THIS MANUAL

The Model 200AU has been designed to provide serviceability, reliability and ease of operation.

The M200AU’s microprocessor continually checks operating parameters such as temperature,

flow, and critical voltages. The instrument’s modular design uses captive screws to facilitate

repair and ease of access. If you encounter any difficulty refer to Section 9 General

Troubleshooting Hints.

We recognize that the need for information in 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 M200AU Front Panel Menus:

The Menu Index (Figure 5-1, Figure 5-2, Table 5-1 and Table 5-2) 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, outlined in the Table of Contents, 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

1. Verify that there is no apparent shipping damage. If damage has occurred please advise

shipper first, then Teledyne API.

CAUTION

To avoid personal injury, always use two persons to

lift and carry the Model 200AU.

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

instrument cover, then refer to Figure 2-1 for screw location.

3. 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.

4. Please check the voltage and frequency label on the rear panel of the instrument for

compatibility with the local power before plugging in the M200AU.

2.2 Electrical and Pneumatic Connections

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

1. Attach the pump to the Exhaust Out port on the instrument rear panel.

2. If you are connecting to a calibrator, attach a vented sample inlet line to the sample inlet

port. The pressure of the sample gas at the inlet port should be at ambient pressure. The

exhaust from the pump should be vented to atmospheric pressure. See Figure 2-3 for inlet

and exhaust line venting recommendations during calibration.

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

datalogger. Refer to Figure 9-4 for the jumper settings for the desired analog output voltage

range. Factory default setting is 0-5VDC.

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

Operation.

WARNING

Analyzer Exhaust –Sample Pump

For brief periods after power-up, analyzer

exhaust may contain ozone.

Make sure pump exhaust is routed to well ventilated

area at atmospheric pressure.

WARNING

Lethal voltages present inside case.

Do not operate with cover off during normal operation.

Before operation check for correct input voltage and frequency for

both the analyzer and the sample pump.

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. After confirming proper supply voltage, turn on the instrument power.

2. The display should immediately light, displaying the instrument type (M200AU) and the

computer's memory configuration. If you are unfamiliar with the M200AU, 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 M200AU requires about 30 minutes for all internal components to come up 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. During this time temperatures and other conditions are out

of specification. Because many warning conditions could be displayed the software

suppresses warning conditions for 30 minutes after power up. After 30 minutes, warning

messages will be displayed until the respective warning conditions are within specifications.

Use the CLR key on the front panel to clear warning messages.

4. While waiting for instrument temperatures to come up, you can check for correct

operation by using some of the M200AU'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. 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 instruments not equipped with the external converter

option, we recommend calibration with zero air and span gas coming in through the sample

port. The procedure is:

1. Press

CAL-CONC-NOX

This key sequence causes the M200AU to prompt for the

expected NO

x

concentration. Enter the NO

x

span

concentration value by pressing the key under each digit until

the expected value is set.

2. Press ENTR ENTR stores the expected NO

x

span value. This value will be

used in the internal formulas to compute subsequent NO

x

concentration values.

3. Press

CAL-CONC-NO

In the same CAL-CONC sub menu press the NO button and

enter the expected NO span value, then ENTR. As before this

value will be used in the internal formulas to compute the

subsequent NO concentration values.

4. Press EXIT-EXIT Returns instrument to SAMPLE mode.

5. Press

SETUP-RNGE-

MODE-SING-ENTR

If necessary, you may want to change ranges. Normally the

instrument is shipped in single range mode set at 500 ppb. We

recommend doing the initial checkout on the 500 ppb range.

6. Press

SETUP-RNGE-SET

After SETUP-RNGE-SET, enter 500 and press ENTR. The

instrument will now be in the 500 ppb range.

7. Press EXIT Returns instrument to SAMPLE mode.

Step 2 - Calibrate the instrument:

Zero/Span Calibration Procedure

Step Number Action Comment

1. Input Zero gas Allow Zero gas to enter the sample port on the rear of the

instrument.

2. Press CAL The M200AU enters the calibrate mode from sample mode.

When the CAL button is pressed, the adaptive filter is

activated. This allows the instrument to respond rapidly to

concentration changes regardless of their magnitude.

3. Wait 10 min Wait for reading to stabilize at the zero value. If you wait less

than 10 minutes the final zero value may drift.

4. Press ZERO The ZERO button will be displayed.

5. Press ENTR Pressing ENTR actually changes the calculation equations and

zeroes the instrument.

6. Input Span Gas Switch gas streams to span gas.

7. Wait 10 min Wait for reading to stabilize at the span value. If you wait less

than 10 minutes the final span value may drift.

8. Press SPAN The SPAN button should be displayed. If it is not, check the

Troubleshooting Section 9.2.8 for instructions on how to

proceed. In certain circumstances at low span gas

concentrations (<100ppb), both the ZERO and SPAN buttons

will appear.

9. Press ENTR Pressing ENTR actually changes the calculation equations so

that the concentration displayed is the same as the expected

span concentration you entered above, thus spanning the

instrument.

10. Press EXIT Pressing EXIT returns the instrument to SAMPLE mode.
