1. INTRODUCTION

This addendum for the Teledyne API Model T300U is a supplement to the T300/T300M manual (P/N 06864) and provides an overview of the instrument operation and specific details regarding those areas where the T300U is different in design or operating method from the T300.

In most ways the T300U is identical to the T300/T300M in design and operation; therefore, most of the basic set up information, operating instructions and calibration, maintenance, troubleshooting and repair methods are the same and can be f ound in the T300/T300M manual (P/N 06864).

1.1. REFERENCE NUMBERING CONVENTION

Unless otherwise specified, section, figure and table reference numbers referred to within this text are relative to this document. EXAMPLE: “Table 2-1” refers to the table within this document.

Additionally, in the electronic version(s) of this manual references internal to this document will be active links to that section, figure or table.

References to sections, figures and tables in other manuals will be labeled as such and will not be an active link. EXAMPLE: “Figure 6.1 of the T300/T300M Operators Manual (P/N 06864)”.

1.2. T300U OVERVIEW

The Model T300U is a close derivative of the T300/T300M CO Ana lyzer; however its higher sensitivity requires some changes to its design and operation, which are documented in this addendum.

The primary differences between the T300U and the T300/T300M analyzers are:

• INTERFERENT REJECTION: Periodically the sample gas stream is routed through an internal CO scrubber allowing the instrument to make a measurement of the sample gas completely free of CO; the measurement made during this autoreference period (A-REF) is subtracted from the sample concentration measurement. This corrects for instrument drift, ambient temperature changes and changing CO

levels in the sample gas.

• OPERATING METHOD: An additional operating mode is added allowing the user to manipulate several parameters associated with the A-REF measurement cycle.

• SAMPLE GAS CONDITIONING: A Nafion



drier is used to dry the sample and

alleviate any effects from humidity changes in the sample gas.

• IR OPTICS: The objective and field mirrors on the optical bench are gold plated. This maximizes their reflectivity and increasing the amount of IR light reaching the detector and improving the optical bench’s signal-to-noise performance.

• PNEUMATIC OPERATION: The flow rate is higher. It has a 1.8 LPM nominal flow rate. The flow sensor is rated to 6 LPM.

• MECHANICAL DESIGN: The optical bench is placed in a temperature-controlled, convection-heated oven. This dramatically reduces instrument noise and temperature related drift.

1.3. CALIBRATION VALVE OPTIONS FOR THE T300U

The hardware options for the T300x family of analyzers are available in the T300U. For a list and descriptions of these options please see Section 1 of the T300/T300M Operators Manual (P/N 06864).

However, the T300U offers one calibration valve option: Ambient Zero and Ambient Span, except that due to the auto-reference gas path and multi-tube Nafion



dryer, this

option has a different gas flow in the T300U versus the T300/T300M.

3. GETTING STARTED

CAUTION

GENERAL SAFETY HAZARD

To avoid personal injury, always use two persons to lift and carry the T300/T300M.

ATTENTION

COULD DAMAGE INSTRUMENT AND VOID WARRANTY

Printed Circuit Assemblies (PCAs) are sensitive to electro-static discharges too small to be felt by the human nervous system. Failure to use ESD protection when working with electronic assemblies will void the instrument warranty. See A Primer on Electro-Static Discharge of the T300/300M manual for more information on preventing ESD damage.

CAUTION!

Do not operate this instrument until you’ve removed dust plugs from SAMPLE and EXHAUST ports on the rear panel!

Note

Teledyne API recommends that you store shipping containers/materials for future use if/when the instrument should be returned to the factory for repair and/or calibration service. See Warranty section in this manual and shipping procedures on our Website at

http://www.teledyne-api.com under Customer

Support > Return Authorization.

3.1. UNPACKING THE T300U

Unpack and install the T300U per the directions in Sections 3.1 and 3.1.1. of the T300/T300M manual (P/N 06864).

3.2. INSTRUMENT LAYOUT

The front pa nel of the T300U is identical to tha t of the T300/T300M (see Figure 3-1 of the T300/T300M Operators Manual, P/N 06864). The Rear Panel is also very similar to that of the T300/T300M (see Figure 3-4 of the T300/T300M Operators Manual, P/N

06864), the only difference being that the instrument’s particulate filter is mounted externally on the upper left side of the rear panel rather than internally as on the T300/T300M.

The internal layout of t he T300U (Figure 3-1) differs from the T300/T300M due to the need to create a thermally insulated, convection-heated oven in which the optical bench temperature is raised and maintained at a high and very stable temperature. Additionally, there is a multi-tube, high flow Nafion



dryer t hat removes moisture from the sample

gas.

3.3. CONNECTIONS AND SETUP

The information found in Section 3.3 of the T300/T300M Operators Manual (P/N

06864) is applicable to the T300U with the exceptions of the Analog and Status Output connections, as described here.

Note

To maintain compliance with EMC standards, it is required that the cable length be no greater than 3 meters for all I/O connections, which include Analog In, Analog Out, Status Out, Control In, Ethernet/LAN, USB, RS-232, and RS-485.

3.3.1. ELECTRICAL CONNECTIONS

The electrical connection instructions in the T300/T300M Operators Manual apply except as differentiated herein.

3.3.1.1. Connecting Analog Outputs

The analog outputs for the T300U are different from those of the T300/T300M. Unlike the T300/T300M which can include options for measuring both O

and CO, the T300U is a single gas analyzer (CO) and therefore does not require the fully configurable version of the analog outputs. The following information replaces the Analog Outputs Section of the T300/T300M Operators Manual.

The T300U is equipped with several analog output channels accessible through a connector on the rear panel of the instrument:

• Channels A1 and A2 output a signal that is proportional to the CO concentration of

the sample gas.

• The default analog output voltage setting of these channels is 0 to 5 VDC with a reporting range of 0 to 500 ppb.

• An optional Current Loop output is available for each.

• The output labeled A4 is special. It can be set by the user to output any one a

variety of diagnostic test functions.

• The default analog output voltage setting of these channels is also 0 to 5 VDC.

• See Section 4.2.2 for a list of available functions.

• There is NO optional Current Loop output is available for Channel A4.

Table 3-1 lists the default settings for each of these channels.

3.5. INITIAL CALIBRATION

3.5.1. PRE-CALIBRATION STABILIZ ATION

Before initially calibrating the T300U it must be allowed to operate for a minimum of 12 hours.

After this stabilization period is complete and just prior to performing the initial calibration, manually initiate an auto-reference measurement by following the instructions in Section 4.4.

3.5.2. BASIC CO CALIBRATION SETUP

Note

The following procedure assumes that the instrument does not have any o f the available Zero/Span Valve Options installed.

To perform the following calibration you must have sources for zero air and span gas available for input into the sample port on the back of the analyzer. See Section 3.3.2.1 of the T300/T300M Operators Manual (P/N 06864) for instructions for connecting these gas sources.

Note

All Gas lines should be PTFE (Teflon), FEP, glass, stainless steel or brass.

3.5.2.1. Calibration Gases

The information found in Section 3.3.2.11 of the T300/T300M Operators Manual (P/N

06864) is applicable to the T300U with the following exception:

ZER O AI R

Zero air is a gas that is similar in chemical composition to the earth’s atmosphere but scrubbed of all components that might affect the analyzer’s readings, in this case CO and water vapor.

For the T300U this gas MUST include at least 5% O

(required for the proper operation

of the analyzer’s CO scrubber). For analyzers without an IZS or external zero air scrubber option, a zero air generator

such as the Teledyne Instruments Model 701 can be used.

Note

The zero air generator MUST be equipped with a hydrocarbon (HC) & CO scrubber option. For the Teledyne Instruments M701, this is Option 2B.

Teledyne API - T300U Addendum to T300/T300M Manual Getting Started

06867D DCN7970 23

3.5.3. BASIC CO CALIBRATION PROCEDURE

The initial calibration should be carried out using the same reporting range set up as used during the analyzer’s factory calibration. This will allow you to compare your calibration results to the factory calibration as listed on the Final Test and Validation Data Sheet.

Because the T300U’s analog output setup differs from that of the T300/T300M and because the T300U could not be modified to include the optional CO

or O2 sensor packages, there are some minor differences in the initial Calibration procedure as described in Section 3.4 of the T300/T300M Operators Manual (P/N 06864).

These differences are:

• STEP 1 - Set Lim it s :

• Reporting Range Limit should be set to 50.000 ppm .

• STEP 2 – Dilution Ratio:

• Ignore this step

• STEP 3 – Set CO Span Gas Concentration

• The CO span gas concentration should be 40.000 ppm

• STEP 4 – Zero/Span CalibratiOn

• Set the display to show the STABILITY test function.

• There is no GAS TO CAL step because there are no gas options to choose in

the T300U.

Ignore Sections 3.4.4.3 and 3.4.4.4 of the T300/T300M Operators Manual (P/N 06864) since they relate to sensor options not available on the T300U.

4. T300U OPERATING INSTRUCTIONS

4.1. SUMMARY OF SETUP AND OPERATION DIFFERENCES BETWEEN T300U AND T300/T300M ANALYZERS.

For the most part the setup and operation instruction for the T300U are the same as those described in Sections 4, 5, and 6 of the T300/T300M manual (P/N 06864) with the following exceptions:

• There are several additional Test functions related to the optical bench’s convection oven and the A-REF cycle (see Section 4.2.2).

• There is and additional warning message related to the optical bench’s convection oven (see Section 3.4.2)

• There is an additional operating mode, AREF, which can be used to force the instrument to make an auto-reference measurement and calculation.

• There are several additional DAS trigger events and parameters (see Appendix A of this addendum).

• The reporting range setup and configuration of the A1 and A2 analog outputs is different (see Section 4.3).

• The optional O

and CO2 sensor packages available for the T300/T300M are not available on the T300U. Ignore all references to these in the T300/T300M Operators Manual (P/N 06864) when operating the T300U.

• The set of available VARS is different (see Section 4.5).

• The set of submenus available under the DIAG menu is slightly different (see

Section 4.6).

• The set of signals available under the DIAG SIGNAL I/O submenu is different (see Appendix A of this addendum).

• Because of the difference in how the analog output ranges are implemented between the T300/T300M and the T300U, there are some differences in DIAG



ANALOG I/O CONFIGURATION submenu (see Section

4.7.1).

• There are no alarm outputs available of the T300U. Ignore Sec ti on 5.10 of the T300/T300M Operators Manual (P/N 06864).

• There is an additional STATUS OUTPUT related to the A-REF cycle (see Section

3.3.2).

• The default Hessen protocol gas ID and status flag list is different from that of the T300/T300M (see Secti on 4.7.4).

4.2.1. AUTO-REFERENCE MODE (A-REF)

One of the most significant differences between the T300/T300M and the T300U analyzers is the auto-reference measurement feature. In this mode, the analyzer makes special measurements and calculations that are applied to the CO concentration calculation to dramatically improve interferent rejection as well as compensate for changes in ambient temperature of the sample gas and age related drift of the optical bench components (see Section 8.1.1 for detailed information about how and when this A-REF feature occurs).

When in A-REF mode, the analyzer:

• Freezes the CO concentration reading displayed on the front panel and output via the analog outputs or COM Ports.

• Displays AUTO-REF in the Mode field of the analyzer’s front panel (see menu chart, Figure 4-1).

• Sets the A-REF status output (pin-7 on the status output connector) to high.

Figure 4-1: Display during A-REF Mode

Note

Initiating a calibration through either the front panel touchscreen, the COM ports or digital control inputs terminates the A-REF mode.

Also, when the instrument is in Calibration Mode, the A-REF mode is suppressed until the instrument exits Calibration Mode.

See Section 4.4 for information about changing the A-REF cycle time or manually initiating an auto-reference measurement.

4.3. SETUP  RNGE: ANALO G OU TP UT REPORTING RANGE CONFIGURATION

4.3.1. PHYSICAL R ANGE VERSU S ANALOG OUTPUT REPORTING

RANGES

Functionally, the T300U analyzer has one hardware “physical range” that is capable of determining CO concentrations between 0 ppb and 100,000 ppb. This architecture improves reliability and accuracy by avoiding the need for extra, switchable, gainamplification circuitry. Once properly calibrated, the analyzer’s front panel will accurately report concentrations along the entire span of its physical range. T300U analyzer’s physical range can create data resolution problems for most analog recording devices. For example, in an application where the expected concentration of CO is typically less than 1000 ppb, the full scale of expected values is only 1% of the instrument’s 100,000 ppb physical range. Unmodified, the corresponding output signal would also be recorded across only 1% of the range of the recording device.

The T300U solves this problem by allowing the user to select a scaled reporting range for the analog outputs that only includes that portion of the physical range relevant to the specific application.

Note

Only the reporting range of the analog outputs is scaled. Both the DAS values stored in the CPU’s memory and the concentration

values reported on the front panel are unaffected by the settings chosen for the reporting range(s) of the instrument.

4.3.2. ANALOG OUTPUT RANGES FOR CO CONCENTRATION

The A1 and A2 channels output a signal that is proportional to the CO c oncent ratio n of the sample gas. They can be configured:

• With independent reporting ranges reporting a “single” output signal (SNGL Mode, see Section 4.3.3).

• Be to operate completely independently (DUAL mode, see Section 4.3.4). In this mode the user can set the measure span and signal scale of each output in a variety of combinations (but not the units of measure).

EXAMPLE: A1 OUTPUT: Output Signal = 0-5 VDC representing 0-1000 ppb concentration

values A2 OUTPUT: Output Signal = 0-10 VDC representing 0-500 ppb concentration

values.

• Or to automatically switch between the two ranges dynamically as the concentration value fluctuates (AUTO modes, see Section 4.3.5).

Both the A1 and A2 outputs can be:

• Configured full scale outputs of: 0 - 0.1 VDC; 0 - 1VDC; 0 - 5VDC or; 0 - 10VDC.

• Equipped with optional 0-20 mADC current loop drivers and configured for any

current output within that range (e.g. 0-20, 2-20, 4-20, etc.).

The user may also add a signal offset independently to each output (see Section 4.7.1) to match the electronic input requirements of the recorder or data logger to which the output is connected.

DEFAULT SETTINGS

The default setting for these the reporting ranges of the analog output channels A1 and A2 are:

• SNGL mode

• 0 to 500.0 ppb

• 0 to 5 VDC

Reporting range span may be viewed via the front panel by viewing the RANGE test function. If the DUAL or AUTO modes are selected, the RANGE test function d will be replaced by two separate functions, RANGE1 & RANGE2. Reporting range status is also available as output via the external digital I/O status bits.

Note

Upper span limit setting for the individual range modes are shared. Resetting the span limit in one mode also resets the span limit for the corresponding range in the other modes as follows:

4.3.3. RNGE  MODE  SNGL: CONFIGURING THE T300U ANALYZER FOR SINGLE RANGE MODE

The single range mode sets a single maximum range for the both the A1 and A2 analog outputs. If the single range is selected both outputs are slaved together and will represent the same reporting range span (e.g. 0-50 ppm), however, their electronic signal levels may be configured for different ranges (e.g. 0-10 VDC vs. 0-0.1 VDC.

4.3.4. RNGE  MODE  DUAL: CONFIGURING THE T300U ANALYZER FOR DUAL RANGE MODE

DUAL range mode allows the A1 and A2 outputs to be configured with separate reporting range spans as well as separate electronic signal levels. The analyzer software calls these two ranges LOW and HI.

• The LOW range setting corresponds with the analog output labeled A1 on the rear panel of the instrument and is viewable via the test function RANGE 1.

• The HIGH range setting corresponds with the A2 output and is viewable via the test function R ANGE 2.

• While the software labels these two ranges as LOW and HI, when in DUAL mode

their upper limits need not conform to that convention. The upper span limit of the LOW/RANGE1 can be a higher number than

that of HI/RANGE 2

Note

Once the units of measurement have been changed, the unit MUST be recalibrated, as the “expected span values” previously in effect will no longer be valid. Simply entering new expected span values without running the entire calibration routine is not sufficient.

The following equations give approximate conversions between volume/volume units and weight/volume units:

CO ppb x 1.25 = CO ug/m

4.4.1. ADJUSTING THE A-REF MODE CYCLE TIME

The auto-reference measurement feature is initiated by the T300U at regular intervals (see Section 8.1.1). It is triggered by the timer feature of the analyzers ACAL system, which uses the instrument’s internal clock.

All T300U analyzers are shipped from the factory the ACAL system enabled (even on instruments without calibration valve options installed) and the first ACAL sequence already programmed and activated with the DELTA TIME parameter set for 4 hours (for a more detailed discussion of the ACAL system see Section 9.4 of the T300/T300M Operators Manual).

This interval time can be changed to fit the specific application in which the T300U is being used. To change the A-REF interval, press:

To configure the analyzer’s three analog outputs, set the electronic signal type of each channel and calibrate the outputs by:

1. Selecting an output type (voltage or current, if an optional current output driver has been installed) and the signal level that matches the input requirements of the recording device attached to the channel.

2. Determining if the over-range feature is needed and turn it on or off accordingly.

3. Considering if a Voltage scale is in use: a bipolar recorder offset may be added to the signal if required.

4. Choosing a Test Channel parameter to be output on the channel.

5. Calibrating the output channel. This can be done automatically or manually for each channel.

4.7.2. ANALOG OUTPUT CALIBRATION

This section corresponds to Section 5.9.3.2 of t he T300/T300M Operators Man ual (P/N

06864).

ANALOG OUPUT calibration needs to be carried out on first startup of the analyzer (performed in the factory as part of the configuration process) or whenever re-calibration is required. The analog outputs can be calibrated automatically, either as a group or individually, or adjusted manually.

During automatic calibration, the analyzer tells the output circuitry to generate a zero mV signal and high-scale point signal (usually about 90% of chosen analog signal scale) then measures actual signal of the output. Any error at zero or high-scale is corrected with a slope and offset.

In its default state, the analyzer is configured for automatic calibration of all channels, which is useful for clearing any analog calibration warnings associated with channels that will not be used or connected to any input or recording device, e.g., datalogger. However, manual calibration should be used for the 0.1V range or in cases where the outputs must be closely matched to the characteristics of the recording device. Manual calibration requires the AUTOCAL feature to be disabled. Automatic group calibration can be performed via the AOUTS CALIBRATION command, or by the DIAG>ANALOG I/O CONFIGURATION menu and pressing the CAL button within each of the output submenus (e.g. CONC_OUT_1, CONC_OUT_2 or TEST_OUTPUT).

5. CALIBRATION PROCEDURES

Calibration of the T300U should be performed according to the procedures described in Sections 9 & 10 of the T300/T300M Manual - P/N 06864 with the following notes and exceptions:

• Delivering span and zero gases for the higher resolution the T300U can be difficult. Attention must be paid to the quality of the gasses, the level of contaminants in the gases as well as the history and conditioning of the gas delivery components.

• The analyzer must be continually operating with and adequate flow of sample gas, for 2 hours prior to performing a calibration (12 hours is recommended for the initial calibration).

• NOTE: DO NOT calibrate the analyzer if it has been turned off or if no sample gas has been flowing though it within the last 2 hours.

• After this stabilization period is complete and just prior to performing the initial calibration, force the instrument to perform an auto-reference measurement by following the instructions in Secti on 4.4.2 .

5.1. REQUIRED EQUIPMENT, SUPPLIES AND EXPENDABLES

• Gas lines to and from the analyzer should be PTFE or FEP Teflon, glass, stainless steel or brass only.

• Zero-air source (defined in Section 9.1.1.1 of the T300/T300M Operators Manual).

• Zero air must include at least 5% O

(required for the proper operation of the

CO scrubber).

• If a zero air generator such as the Teledyne Instruments M701 is used, it MUST

be equipped with a hydrocarbon (HC) & CO scrubber option. For the Teledyne Instruments M701, this is Option 2B.

• Span gas source (defined in Section 9.1.1.3 of the T300/T300M Operators Manual).

• A recording device such as a strip-chart recorder and/or data logger (optional).

Data recording device should be capable of bi-polar operation so that negative readings can be recorded.

• For electronic documentation, the internal data acquisition system can be used.

Note

If any problems occur while performing the following calibration procedures, refer to Section 11 of this manual for troubleshooting tips

5.2. MANUAL CALIBRATION

The information found in Section 9.2 of the T300/T300M Operators Manual (P/N

06864) is applicable to the T300U with the following exception(s).

• Zero/Span Calibration

• Set the display to show the STABILITY test function (same as the CO STB

function mentioned in the T300/T300M operator’s manual).

• There is no GAS TO CAL step because the T300U cannot be modified to

include the O

and CO2 sensor packages.

• The oven temperature should be tracked along with the other parameters listed on Table 11-2 of the T300/T300M Operators Manual (see Table 7-1 below).

7.1. PERFOMING AN AUTO-REFERENCE MEASUREMENT AFTER MAINTENANCE

It is very important to manually initiate an A-REF measurement whenever any maintenance is performed on the T300U, particularly if that maintenance is involves:

• Opening the top cover or the front panel while the instrument is making A-REF measurements.

• Opening the top cover or the front panel at any time when the next ACAL scheduled A-REF measurement cycle is < 2 hours away.

• Turning off the analyzer at any time when the next ACAL scheduled A-REF measurement cy cle is < 2 hours away.

This should be done no sooner than 2 hours after the T300U has been operating with the front panel / top cover properly closed and sealed. One this manual A-REF measurement is performed; the analyzer will discard any erroneous A-REF ratios that may have been recorded before the instrument’s oven temperature had a chance to restabilize.

8. PRINCIPLES OF OPERATION

8.1. MEASUREMENT METHOD

The information found in Section 13.1 of the T300/T300M Operators Manual (P/N

06864) is applicable to the T300U with the following addition. It is recommended that

you read that section before continuing.

8.1.1. AUTO-REFERENCE (A-REF) RATIO

The high er r esol ution of the T300U makes it more susceptible then the T300/T300M to the effects of a variety of environmental conditions such as:

• Drift related to the age of the optical bench components ( e.g. the IR lamp, the IR detector, etc.)

• Variations in the temperature of the sample gas (affecting it density).

• Interferents, specifically CO

and H2O.

The T300U accounts for these issues by adding an additional component to the CO concentration calculation call the Auto-reference ratio.

This ratio is arrived at in the same manner as the measure/reference ratio (described in Section 13.2.1.2 of the T300/T300M Operators Manual) with the difference that that during the measurements that are to calculate the A-REF ratio, the gas stream is switched to pass through a scrubber that completely removes all CO from the sample gas. Therefore the measured difference between CO MEAS and CO R EF represents the exact state of the sample gas and the optical bench’s sensors without CO present.

The analyzer averages the last five A-REF ratios and multiplies this average by a constant and the result is included in the final CO calculation as a positive o r negative offset.

Whenever an A-REF is manually initiated either by using the AREF submenu via the front panel (see Section 4.4.2) or by a ctivatin g pin-7 of the instrument’s digital control input connector, all previously stored A-REF ratios are erased and the new ratio inserted. This allows the user to correct for a bad A-REF reading (e.g. the oven temperature during the A-REF cycle was too high/low)

The auto-reference measurement takes approximately 15 minutes. To ensure that the sample chamber of the optical bench is properly purged when switching

between the sample and auto-reference measurements and vice-versa, each autoreference cycle includes a 3 minute dwell period before and after the actual measurements are made. This cycle is restarted every 4 hours by an ACAL sequence, programmed at the factory (see Section 4.4).

8.2.1. THE A-REF CARBON MONOXIDE SCRUBBER

A special CO scrubber is used to remove all of the CO from the gas stream when the instrument is performing an auto-reference measurement. The scrubber contains a substance that catalyses a chemical reaction converting any CO in the gas stream to CO

Note

To operate properly, the gas flowing though the scrubber must contain at least 5% O2.

This includes calibration gases such as zero air and span gas.

8.2.2. THE A-REF VALVE ASSEMBLY

The aut o-reference valve assembly is located next to the optical bench, at the re ar of t he analyzer between the Nafion



dryer and the outer wall of the instrument (see Figure 3-1). The following table describes the state of each valve during the analyzer’s various operational modes (see Figure 8-1).

8.2.3. THE NAFION DRYER.

Normal room air contains a certain amount of water vapor. While H2O is a very lowlevel interferent for IR absorption (in the same range as CO) it can cause enough interference to affect the high-resolution measurements of the T300U.

To account for this the T300U has a special dryer added to the gas stream. The dryer consists of a bundle of parallel tubes of Nafion

, a co-polymer similar to Teflon® that absorbs water very well but not other chemicals. The multiple tube design of this dryer creates a large reactive surface without causing a restriction in the higher gas flow rate required by the T300U that a long single tube style dryer would.

Figure 8-3: Semi-Permeable Membrane Drying Process

Teledyne API - T300U Addendum to T300/T300M Manual Principles of Operation

06867D DCN7970 63

The dryer consists of a bundle of 0.030" O.D. Nafion tubes housed within a single large tube shell. Sample gas flows within the Nafion tubes while water vapor absorbs into the tubular membrane walls and is removed. Moisture permeating the tubing is carried away by a dry purge gas within the shell that flows countercurrent to the sample gas.

This process is called per-evaporation and is driven by the humidity gradient between the inner and outer tubes as well as the flow rates and pressure difference between inner and outer tubing. Unlike micro-porous membrane permeation, which transfers water through a relatively slow diffusion process, per-evaporation is a simple kinetic reaction. Therefore, the drying process occurs quickly, typically within milliseconds.

The first step in this process is a chemical reaction between the molecules of the Nafion

material and water, other chemical components of the gases to be dried are usually unaffected. The chemical reaction is based on hydrogen bonds between the water molecule and the Nafion material. Other small polar gases that are capable of hydrogen bonds can be absorbed this way, too, such as ammonia (NH

) and some low molecular amines. The gas of interest to the T300U, CO, does not get absorbed and passes though the dryer unaltered.

To provide a dry purge gas for the outer side of the Naf ion tube, the T300U returns some of the dried air from the inner tube to the outer tube (see Figure 3-3).

When the analyzer is first started, or if the instrument is turned on after having been off for more than 30 minutes, the humidity gradient between the inner and outer tubes is not very large and the dryer’s efficiency is low at first but improves as this cycle reduces the moisture in the sample gas and settles at a minimum humidity.

The dryer used in the T300U is capable of adequately drying ambient air to a dew point of ≤ -6˚C (~4000 ppm residual H

O) at the flow rate of the analyzer.

• There are two heaters attached to either side of the optical bench (see Figure 3-1)

that radiate heat into the insulated, oven area of the analyzer. Each heater has a fan attached to it that circulates the heated air throughout the oven airspace.

• The CPU senses the temperature level form different places inside the oven area

and determines the overall temperature of the oven. Eventually, all of the components within the oven area will stabilize at the same temperature. This usually takes about 24 hours after the instrument is turned ON.

• A separate fan blows directly on the A-to-D conversion circuitry of the motherboard

to more keep it at the same temperature as the oven airspace in order to eliminate any temperature-coefficient related offset.

8.3.3. MOTHERBOARD

The information found in Section 13.4.5 of the T300/T300M Operators Manual (P/N

06864) is applicable to the T300U with the following additions:

8.3.3.1. A to D Conversion

Because the T300U has much higher resolution and sensitivity than the T300/T300M, the possibility that temperature-coefficient related drift could occur in the 10.3.3.1. A to D conversion circuitry if there were a significant difference in temperature between the converter and the surrounding airspace. To prevent this, a fan direct heated air directly onto the A to D converter area of the motherboard to ensure that it is as close as possible to the current temperature of the oven area.

8.3.3.2. Sensor Inputs

OVEN TEMPERATURE SENSOR

A thermistor is located in the center of the insulated oven area (see Figure 3-1). It measures the analyzer’s inside temperature. This information is stored by the CPU and can be viewed by the user for troubleshooting purposes via the front panel display by selecting the test function OVEN TEMP or reported via the instruments TEST

CHANNEL analog output (A4) by setting the output function also named OVEN TEMP.

9.3. GAS FLOW PROBLEMS

Along with the information found in Section 12.2 of the T300/T300M Operators Manual (P/N 06864), also be aware that problems with the flow of gas through the Nafion



dryer could also be a cause of pressure or flow problems through the T300U. Poor gas flow or leaks related to the dryer can also cause it to not dry the sample gas efficiently allowing extra H

O to interfere with the analyzer’s CO measurements.

In addition to the checks described in the T300/T300M Operators Manual

• Check for blockages in the dryer.

• Check for leakage in and around the dryer and its fixtures (both the wet gas stream

and the purge gas inlets/outlets.

If it becomes necessary to replace the Nafion dryer, contact Teledyne Instruments’ Customer Service (see Section 9.6) for parts and instructions.

9.4. OTHER PERFORMANCE PROBLEMS

The information found in Section 12.4 of the T300/T300M Operators Manual (P/N

06864) is applicable to the T300U with the following addition.

9.4.1. UNEXPLAINED DRIFT

Because the T300U makes higher resolution CO measurements than the T300/T300M, subtle issues with certain subsystems that would be unimportant for the T300/T300M can affect its accuracy: The most common of these are:

• Temperature Coefficient issues related to the motherboard’s A-to-D converter

• Age related changes to some of the optical bench components (e.g. the mirrors, the

IR source, the IR detector, etc.)

• Ambient changes in the condition of the instrument or the sample gas.

If a drift problem exists and calibrating the instruments zero and span points does not correct the problem or there is no obvious component failure, perform the following operations in order:

1. Let the analyzer run uninterrupted for at least 24 hours.

• This will ensure that the entire oven area and all of the components therein have reached an equal and stabile temperature.

2. Perform an Internal A-to-D Converter calibration (see Section 5.9.3.10 of the T300/T300M Operators Manual).

• This should solve any issues related to the A/D converter.

3. Perform a Dark Calibration of the Optical Bench (see Section 9.6.1 of the T300/T300M Operators Manual).

• This should account for any issues related to changes in the optical bench

components.

4. Manually initiate an A-REF cycle (see Section 4.4.2).

• This should account for any issues related to changes in the ambient conditions

of the sample gas.

9.5.2. MOTHERBOARD

9.5.2.1. A/D Functions

The T300U makes higher resolution CO measurements than the T300/T300M means that it is susceptible to temperature coefficient issues related to the motherboard’s A-toD converter that could occur if the temperature of the motherboard differs significantly from that of the rest of the analyzer’s oven area.

• Compare the values of the BOX TEMP & OVEN TEMP test functions. If they are significantly different check the function of the:

• Oven theaters.

• The oven heater fans.

• The motherboard stabilization fan.

• The relays controlling the oven heaters.

• No abnormal blockages to airflow inside the oven area exist.
