M300EU INTRODUCTION

Addendum to M300EU Manual - P/N 04288

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

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

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

• 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

humidity changes in the sample gas.

drier is used to dry the sample and alleviate any effects from

• 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.

3. 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

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.

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

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 A­REF 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
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).

and CO2 sensor packages available for the M300E/EM are not available ton the

• 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.

• Displays the Message AUTO-REF in the mode filed of the analyzer’s front panel.

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

NOTE:

Initiating a calibration through either the keyboard, the COMM 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 6.4 for information about changing the A-REF cycle time or manually initiating an auto-reference

measurement.
