Addendum to M300EU Manual - P/N 04288

INTRODUCTION

1.

INTRODUCTION

This addendum is based on the M300E/EM Operators Manual (P/N 04288). It is intended as a supplement to the M300E/EM manual (P/N 04288) and provides an overview of the instrument operation and specific details regarding those areas where the M300EU is different in design or operating method from the M300E.

In most ways the M300EU is identical to the M300E/EM in design and operation, therefore most of the basic set up information, operating instructions as well as calibration, maintenance, troubleshooting and repair methods are the same and can be found in the M300E/EM manual (P/N 04288).

1.1. REFERENCE NUMBERING CONVENTION

Unless otherwise specified, chapter, section, figure and table reference numbers referred to within this text are relative to this document.

• EXAMPLE: “Table 2-1” refers to the figure, within this document, labeled as 2-1.

• 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 chapters, sections, figures and tables in the original document will be labeled as such and will not be an active link.

• EXAMPLE: “Figure 6.1 of the M300E/EM Operators Manual (P/N 04288)”.

1.2. M300EU OVERVIEW

NOTE

The information contained in this addendum is relevant to M300EU analyzers running: SOFTWARE

REVISION K.6. Some or all of the information may not be applicable to earlier or later revisions of software.

The software revision your analyzer is running is displayed in the upper left-hand corner of the display any time the instrument is in SETUP mode.

The model 300EU is a close derivative of the M300E/EM CO Analyzer, however its higher sensitivity require some changes its design and operation.

The primary differences between the M300EU and the M300E/EM 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 auto-reference period (A-REF) is subtracted from the sample concentration measurement. This corrects for instrument drift, ambient temperature changes and changing CO

2

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.

GETTING STARTED

3.1. UNPACKING THE M300EU

Unpack the M300EU as per the directions in Section 3.1 of the M300E/EM manual (P/N 04288), with the exception that there are no shipping screws.

3.2. M300EU ANALYZER LAYOUT

The front panel of the M300EU is identical to that of the M300E/EM (see Figure 3-1 of the M300E/EM Operators

Manual (P/N 04288). The Rear Panel is also very similar to that of the M300E/EM, 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 M300E/EM.

On the other hand, the internal layout of the M300EU is quite different from the M300E/EM. Most of these differences are related 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 multitube, high flow Nafion

®

dryer that removes moisture from the sample gas.

3.3. ELECTRICAL CONNECTIONS

The information found in Section 3.1.2 of the M300E/EM Operators Manual (P/N 04288) is applicable to the

M300EU with the following exceptions.

3.3.1. POWER CONNECTION

The information found in Section 3.1.2.1 of the M300E/EM manual (P/N 04288) is correct for the M300EU.

M300EU


3.3.2. ANALOG OUTPUT Connections


The analog outputs for the M300EU are different from those of the M300E/EM. Unlike the M300E/EM which can include options for measuring both O

2

and CO, the M300EU is a single gas analyzer (CO) and therefore does not require the fully configurable version of the analog outputs. The following information replaces that found in

Section 3.1.2.2 of the M300E/EM Operators Manual (P/N 04288).

The M300EU is equipped with several analog output channels accessible through a connector on the back 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 6.2.2 for a list of available functions.

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

The following table lists the default settings for each of these channels.

3.4. INITIAL OPERATION OF THE M300EU


NOTE

The analyzer’s cover must be installed and securely fastened to ensure that the convection oven portion of the internal layout is capable of properly creating and controlling temperatures of the analyzer’s optical bench.

3.4.1. STARTUP AND WARM UP OF THE M300EU

The process for starting and warming up the M300EU is identical to that described in Sections 3.2.1 and 3.2.2 of the M300E/EM Operators Manual (P/N 04288) except:

• It is best to alloy the M300EU to operate uninterrupted for at least 2 hours to allow the temperature of all areas of the convection oven area to equalize.

3.5. INITIAL CALIBRATION


3.5.1. PRE-CALIBRATION STABILIZATION

Before initially calibrating the M300EU 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 6.4.

3.5.2. BASIC CO CALIBRATION SETUP

NOTE

The following procedure assumes that the instrument does not have any of 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 3.1.3 of the M300E/EM Operators Manual (P/N 04288) 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 3.1.3.2 of the M300E/EM Operators Manual (P/N 04288) is applicable to the

M300EU with the following exception:

ZERO AIR

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

For the M300EU this gas MUST include at least 5% O analyzer’s CO scrubber).

(required for the proper operation of the

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

05514 Rev A1 11


3.5.3. BASIC CO CALIBRATION PROCEDURE

M300EU


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 M300EU’s analog output setup differs from that of the M300E/EM and because the M300EU cannot have be modified to include the optional CO

sensor packages, there are some minor differences in the initial Calibration procedure as described in Section 3.3 of the M300E/EM Operators Manual (P/N 04288).

These are:

• STEP 1 - SET LIMITS:

• 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 the M300EU cannot be modified to include the O

M300EU OPERATING INSTRUCTIONS

6.1. SUMMARY OF DIFFERENCES BETWEEN OPERATING

THE M300EU AND THE M300E/EM ANALYZERS.

For the most part the operation instruction for the M300EU are the same as those described in Chapter 6 of the

M300E/EM manual (P/N 04288) with the following exceptions:

• There are several additional Test functions related to the optical bench’s convection oven and the A-

REF

cycle (see Section6.2.2).

• 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 iDAS 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

6.3).

• The optional O

sensor packages available for the M300E/EM are not available ton the

M300EU. Ignore all references to these in the M300E/EM Operators Manual (P/N 04288) when operating the M300EU.

• The set of available VARS is different (see Section 6.5.

• The set of submenus available under the DIAG menu is slightly different (see Section 6.6).

• The set of signals available under the DIAG ÆSIGNAL 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 M300E/EM and the M300EU, there are some differences in DIAGÆ ANALOG I/O CONFIGURATION submenu

(see Section 6.7.1).

• There are no alarm outputs available of the M300EU. Ignore Section 6.14 of the M300E/EM Operators

Manual (P/N 04288).

• There is an additional STATUS OUTPUT related to the A-REF cycle (see Section 3.3.3).

• The default Hessen protocol gas ID and status flag list is different from that of the M300E/EM (see

Section 6.7.4).

6.2.1. AUTO-REFERENCE MODE (AREF)

One of the most significant differences between the M300E/EM and the M300EU 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 t for changes in ambient temperature of the sample gas and age related drift of the optical bench components

(see Section 10.1.1 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. the status output (pin-7 on the status output connector) to high.

6.3. SETUP Æ RNGE: ANALOG OUTPUT REPORTING

RANGE CONFIGURATION

6.3.1. PHYSICAL RANGE VERSUS ANALOG OUTPUT REPORTING

RANGES

Functionally, the M300EU 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, gain-amplification circuitry. Once properly calibrated, the analyzer’s front panel will accurately report concentrations along the entire span of its physical range. M300EU 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 M300EU 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 iDAS 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.

6.3.2. ANALOG OUTPUT RANGES FOR CO CONCENTRATION

The analyzer has two active analog output signals related to CO concentration that are accessible through a connector on the rear panel.

M300EU


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

• With independent reporting ranges reporting a “single” output signal (SNGL Mode, see Section 6.3.3) o

• Be to operate completely independently (DUAL mode, see Section 6.3.4). 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 6.3.5).

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 6.7.1) 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:

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-.1 VDC.

6.3.4. RNGE Æ MODE Æ DUAL: CONFIGURING THE M300EU 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 RANGE 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

6.3.5. RNGE Æ MODE Æ AUTO: CONFIGURING THE M300EU ANALYZER

FOR AUTO RANGE MODE

AUTO range mode gives the analyzer to ability to output data via a LOW range (displayed on the front panel as

RANGE1 ) and HIGH range (displayed on the front panel as RANGE2) on a single analog output.

When the AUTO range mode is selected, the analyzer automatically switches back and forth between userselected LOW & HIGH ranges depending on the level of the CO concentration.

• The unit will move from LOW range to HIGH range when the CO concentration exceeds to 98% of the

LOW range span limit.

• The unit will return from HIGH range back to LOW range once the CO concentration falls below 75% of the LOW range span limit.

To set the ranges press following keystroke sequence:

NOTE

Avoid accidentally setting the LOW range (RANGE 1) of the instrument with a higher span limit than the

HIGH range (RANGE 2). This will cause the unit to stay in the low reporting range perpetually and defeat the function of the AUTO range mode.

6.4.1. ADJUSTING THE A-REF MODE CYCLE TIME

The auto-reference measurement feature is initiated by the M300EU at regular intervals (see Section 10.1.1). It

is triggered by the timer feature of the analyzers ACAL system, which uses the instrument’s internal clock.

All M300EU 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 7.7 of the M300E/EM Operators Manual).

SIGNAL I/O:

Allows observation of all digital and analog signals in the instrument. Allows certain digital signals such as valves and heaters to be toggled ON and OFF.

ANALOG OUTPUT:

When entered, the analyzer performs an analog output step test. This can be used to calibrate a chart recorder or to test the analog output accuracy.

ANALOG I/O CONFIGURATION:

This submenu allows the user to configure the analyzer’s four analog output channels, including choosing what parameter will be output on each channel. Instructions that appear here allow adjustment and calibration the voltage signals associated with each output as well as calibration of the analog to digital converter circuitry on the motherboard.

ELECTRIC TEST:

The analyzer is performing an electric test. This test simulates IR detector signal in a known manner so that the proper functioning of the sync/demod board can be verified.

DARK CALIBRATION:

The analyzer is performing a dark calibration procedure. This procedure measures and stores the inherent dc offset of the sync/demod board electronics.

PRESSURE CALIBRATION:

The analyzer records the current output of the sample gas pressure sensor. This value is used by the CPU to compensate the CO concentration.

FLOW CALIBRATION:

This function is used to calibrate the gas flow output signals of sample gas and ozone supply. These settings are retained when exiting DIAG.

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

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

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

4. Choose 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.

6.7.2. CALIBRATION OF THE ANALOG OUTPUTS

This section replaces Section 6.13.6 of the M300E/EM Operators Manual (P/N 04288).

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 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.

Automatic calibration can be performed via the AOUTS CALIBRATION command, or by using the CAL button located inside each of the output submenus (e.g. CONC_OUT_1, CONC_OUT_2 or TEST_OUTPUT). By default, the analyzer is configured so that calibration of analog outputs can be initiated as a group with the

AOUT CALIBRATION command or individually.

CALIBRATION PROCEDURES

Calibration of the M300EU should be performed according to the procedures described in Chapters 7 & 8 of the

M300E/EM Manual - P/N 04288 with the following notes and exceptions:

• Delivering span and zero gases for the higher resolution the M300EU 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).

• DO NOT calibrate the analyzer if it has been turned off or if no sample gas has been flow 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 Section 6.4.2 .

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 7.1.2 of the M300E/EM Operators Manual).

• Zero air must include at least 5% O

2

(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 7.1.3 of the M300E/EM 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 Chapter 11 of this manual for troubleshooting tips.

MANUAL CALIBRATION



• STEP3 – ZERO/SPAN CALIBRATION

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

INSTRUMENT MAINTENANCE

The information found in Chapter 9 of the M300E/EM Operators Manual (P/N 04288) is applicable to the M300EU with the following exception(s):

• The oven temperature should be tracked along with the other parameters listed on Table 9-2 of the

M300E/EM Operators Manual (see Table 9-1 below).

9.1. 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

M300EU, 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 cycle is < 2 hours away.

This should be done no sooner than 2 hours after the M300EU 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 re-stabilize.

THEORY OF OPERATION

10.1. MEASUREMENT METHOD

THEORY OF OPERATION


M300EU with the following addition. It is recommended that you read that section before continuing.

10.1.1. AUTO-REFERENCE RATIO

The higher resolution of the M300EU makes it more susceptible then the M300E/EM 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

2

and H

2

O.

The M300EU 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 10.1.3.2 of the

M300E/EM 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 REF represents the exact state of the sample gas and the optical bench’s sensors without CO present.

Figure 10-1: M300EU Gas flow during Auto-Reference Measurements

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 or negative offset.

Whenever an A-REF is manually initiated either by using the AREF submenu via the front panel (see Section

6.4.2) or by activating 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)

05514 Rev A1 49


M300EU


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 auto-reference 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 6.4).

Figure 10-2: Auto-Reference Measurement Cycle

10.2. PNEUMATIC OPERATION

With the exceptions to the difference discussed on other portions of this addendum regarding the A-REF CO scrubber and the Nafion

®

dryer, (See Sections 3.2, 5.1.1, 5.1.2, 5.1.3, 10.1.1 & 0) the pneumatic operation is the

same as that described in Section 10.3 of the M300E/EM Operators Manual (P/N 04288).

10.2.1. 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

2

.

NOTE

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

2

.

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

The O

3

scrubber is located inside the auto-reference valve assembly.

50 05831 Rev. 01

M300EU


10.2.2. THE A-REF VALVE ASSEMBLY


The auto-reference valve assembly is located next to the optical bench, at the rear of the 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 10-1).

10.2.3. THE NAFION

®

DRYER.

Normal room air contains a certain amount of water vapor. While H absorption (in the same range as CO) it can cause enough interference to affect the high-resolution measurements of the M300EU.

2

O is a very low-level interferent for IR

To account for this the M300EU 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 M300EU that a long single tube style dryer would.

05514 Rev A1

Figure 10-3: Semi-Permeable Membrane Drying Process

51


M300EU


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

3

) and some low molecular amines.

The gas of interest to the M300EU, CO, does not get absorbed and passes though the dryer unaltered.

To provide a dry purge gas for the outer side of the Nafion tube, the M300EU returns some of the dried air from

the inner tube to the outer tube (see Figure 3-2).

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 M300EU is capable of adequately drying ambient air to a dew point of ≤ -6˚C (~4000 ppm residual H

2

O) at the flow rate of the analyzer.

10.3.2. THE RELAY PCA



10.3.2.1. Temperature Control of the Convection Oven



• 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 2 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.

10.3.3. MOTHERBOARD


M300EU with the following additions:

10.3.3.1. A to D Conversion

Because the M300EU has much higher resolution and sensitivity than the M300E/EM, 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.

10.3.3.2. 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.

11.3. GAS FLOW PROBLEMS


Along with the information found in Section 11.2 of the M300E/EM Operators Manual (P/N 04288), also be aware that problems with the flow of gas through the Nafion problems through the M300EU. Poor gas flow or leaks related to the dryer can also cause it to not dry the sample gas efficiently allowing extra H

2

®

dryer could also be a cause of pressure or flow

O to interfere with the analyzer’s CO measurements.

In addition to the checks described in the M300E/EM 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 11.6) for parts and instructions.

11.4. OTHER PERFORMANCE PROBLEMS


M300EU with the following addition.

11.4.1. Unexplained DRIFT

Because the M300EU makes higher resolution CO measurements than the M300E/EM, subtle issues with certain subsystems that would be unimportant for the M300E/EM 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 un interrupted for at least 2 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 6.13.6.5 of the M300E/EM Operators

Manual).

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

3. Perform a Dark Calibration of the Optical Bench (see Section 6.13.7.2 of the M300E/EM 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 6.4.2).

• This should account for any issues related to changes in the ambient conditions of the sample gas.

The M300EU makes higher resolution CO measurements than the M300E/EM means that it is susceptible to temperature coefficient issues related to the motherboard’s A-to-D 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.
