 1-8 INTRODUCTION
Model 700

The GC-PC interface provides the user with the

greatest capability, ease-of-use, and flexibility.
One PC running MON 2000 can connect with
up to 32 chromatographs (via RS-485 serial
communications links). MON 2000 is used to
edit applications, monitor operations, calibrate
streams, and display analysis chromatograms
and reports, which can then be stored to files
on the PC hard drive or printed from either the
PC printer port or the GC printer port.

Sample Conditioning System (SCS)

The sample conditioning system is located

between the process stream and the Analyzer
Assembly sample inlet (mounted on the lower
portion of the Analyzer Assembly stand). The
standard configuration includes a Stream
Switching System and filters.

The Model 700 electronics and hardware are

housed in two explosion-proof enclosures and
meet IEC Class I, Zone 1, Ex d IIB+H2, T4
(NEC Class 1, Division 1, Groups B, C, and D)
approval for use in a hazardous environment.

System Description SEPTEMBER 2007

 INTRODUCTION 1-9
Model 700

1.2.1 Functional Description

A sample of the gas to be analyzed is taken

from the process stream by a sample probe
installed in the process line. The sample passes
through a sample line to the SCS where it is
filtered or otherwise conditioned. After
conditioning, the sample flows to the Analyzer
Assembly for separation and detection of the
gas components.

DANGER TO PERSONNEL AND EQUIPMENT

Do not use a PC or a printer in a hazardous area.
Serial port and Modbus communications links are
provided to connect the unit to the PC and to
connect to other computers and printers in a safe
area.
Failure to follow this warning may result in injury or
death to personnel or cause damage to the
equipment.

The chromatographic separation of the sample

gas into its components is accomplished in the
following manner. A precise volume of sample
gas is injected into one of the analytical
columns. The column contains a stationary
phase (packing) that is either an active solid or
an inert solid support that is coated with a
liquid phase (absorption partitioning). The
sample gas is moved through the column by
means of a mobile phase (carrier gas). The
selective retardation of the components takes
place in the column, causing each component to
move through the column at a different rate.
This separates the sample into its constituent
gases and vapors.

SEPTEMBER 2007 Functional Description

 1-10 INTRODUCTION
Model 700

A detector located at the outlet of the analytical

column senses the elution of components from
the column and produces electrical outputs
proportional to the concentration of each
For additional information,
see Section 1.4 component. Outputs from the detector(s) are
amplified in the Analyzer Assembly electronics,
then transmitted to the Controller Assembly
for further processing.

Output from the Controller Assembly is

normally displayed on a remotely located PC or
a printer. Connection between the Controller
Assembly and the PC can be accomplished via a
direct serial line or via a Modbus-compatible
communication interface.

Several chromatograms may be displayed via

MON2000, with separate color schemes,
allowing the user to compare present and past
data.

Use of the MON2000 software for configuration

and troubleshooting procedures is essential in
most cases. The PC may be remotely connected
via telephone, radio or satellite communica-
tions. Once installed and configured, the Model
700 can operate independently for long periods
of time.

1.3 SOFTWARE DESCRIPTION

The MON2000 uses three distinct types of

software. This enables total flexibility in
defining the calculation sequence, printed
report content, format, type and amount of
data for viewing, control and/or transmission to
another computer or Controller Assembly. The
three types are:

Baseline Operating System (BOS)

Application configuration software
Maintenance and Operations software
(MON2000 version 2.2 or later)

The BOS and the Application configuration

software are installed when the
Model 700 system is shipped. The application
configuration is tailored to the customers
process and shipped on a floppy disk. Note that
the hardware and software are tested together
as a unit before the equipment leaves the
factory. The MON2000 software program
communicates with the Model 700 system and
allows an initial site system setup (i.e.,
operational parameters, application
modifications, and maintenance).

BOS

The Baseline Operating System (BOS)

supervises operation of the Model 700 through
its internal microprocessor-based controller; all
direct hardware interface is via this control
software. It consists of a multi-tasking program
that controls separate tasks in system
operation, as well as hardware self-testing,
user application downloading, start-up, and
communications. Once configured, a Model 700
can operate as a stand alone unit.

SEPTEMBER 2007 Software Description

 1-14 INTRODUCTION
Model 700

MON2000

MON2000, available as a Windows-based

program, provides the human-machine
interface for maintenance, operation, and
troubleshooting. It allows the user to download
applications developed for a specific GC unit.
MON2000 provides operator control of the
connected Model 700, monitors analysis
results, and inspects and edits various
parameters that affect Model 700 operation. It
also controls display and printout of the
chromatograms and reports, and it stops and
starts automatic analysis cycling or calibration
runs.

After the equipment/software has been

installed and the operation stabilized,
automatic operation can be initiated. The link
between the MON2000 computer and the
Model 700 can either be direct, via a local serial
connection or remote, via an ethernet network,
modems, telephone lines and/or radio.

Operation of multiple Model 700

chromatographs (up to 32) with a single
MON2000 computer, via a multi-drop serial
link, is also supported.

terminology used in the
following explanations. 1.4.1 Thermal Conductivity Detector (TCD)

One of the detectors (located on the oven in the

Analyzer upper assembly) is a thermal
conductivity detector that consists of a
balanced bridge network with heat sensitive
thermistors in each leg of the bridge. Each
thermistor is enclosed in a separate chamber of
the detector block.

One thermistor is designated the reference

element and the other the measurement
element. See Figure 1-5 for a schematic
diagram of the thermal conductivity detector
(TCD).

SEPTEMBER 2007 Theory of Operation

 1-16 INTRODUCTION
Model 700

Figure 1-5 Analyzer Assembly with TCD Detector Bridge

In the quiescent condition (prior to injecting a

sample), both legs of the bridge are exposed to
pure carrier gas. In this condition, the bridge is
balanced and the bridge output is electrically
nulled. (The bridge can be balanced by the fine
and coarse adjustment potentiometers located
on the preamplifier circuit board.)

The analysis begins when a fixed volume of

sample is injected into the column by operation
of the sample valve. The sample is moved
through the column by the continuous flow of
carrier gas. As successive components elute
from the column, the temperature of the
measurement element changes.

Thermal Conductivity Detector (TCD) SEPTEMBER 2007

 INTRODUCTION 1-17
Model 700

The temperature change unbalances the bridge

and produces an electrical output proportional
to the component concentration.

The differential signal developed between the

two thermistors is amplified by the
preamplifier. Figure 1-6 illustrates the change
in detector electrical output during elution of a
component.

Figure 1-6 Detector Output During Component Elution

In addition to amplifying the differential signal

developed between the two thermistors, the
preamplifier supplies drive current to the
detector bridge. The voltage signal is converted
to a 4-20 milliampere (mA) current loop for
transmission to the Controller Assembly.

The signal is proportional to the concentration

of a component detected in the gas sample. The
preamplifier provides four different gain
channels as well as compensation for baseline
drift.

SEPTEMBER 2007 Thermal Conductivity Detector (TCD)

 1-18 INTRODUCTION
Model 700

The signals from the preamplifier are sent to

the Controller Assembly for computation,
recording on a printer, or viewing on a PC
monitor (via MON2000).

1.4.2 Flame Ionization Detector (Micro-FID)

The other detector (located on the oven in the

Analyzer Assembly) is a Flame Ionization
Detector. The Micro-FID requires a
polarization voltage and its output is connected
to the input to a high impedance amplifier
which is called an Electrometer. The burner
uses a mixture of hydrogen and air to maintain
the flame. The sample of gas to be measured is
also injected into the burner. See Figure 1-7 for
a schematic diagram of the Flame Ionization
Detector (Micro-FID).

The outermost end houses an air operated

piston. Air at 15 to 45 psi is directed by a
solenoid valve to either advance the stem to
inject the sample or to retract the stem.

The next section houses an auxiliary stem seal

assist. A piston driven by air at 80 to 100 psi
keeps adequate load on the stem seal to
counteract wear at the high temperatures and
pressures that might be encountered. There
are two "npt ports in this section; one port
retracts the sample piston and the other port
activates the seal assist.

 1-20 INTRODUCTION

The innermost section houses the stem seals

and the sample chamber. There are five " npt
ports in this section.

Within the enclosure cavity are the flash

chamber components surrounded with
insulating covers. At working temperatures,
the surfaces of these covers become very hot to
the touch.

The tip of the LSIV is the port where flashed

sample is taken to the oven system.

The port at right angles to the length of the

LSIV is the input for carrier gas.

The heater block, a cylinder of aluminum, is

installed off-center surrounding the flash
chamber, close to the wall of the upper
enclosure. It houses the heater and an RTD
and is retained by a jamb nut that should only
be finger tight.

1.4.4 Methanator

After all other components have been

separated from the sample, normally
undetectable CO and CO2 are sent through the
methanator. They are combined with hydrogen
to make methane in a heat generated catalytic
reaction. The methanator is also known as a
methanizer or a catalytic converter.

1.4.5 Data Acquisition

Every second, exactly 40 equi-spaced data

samples are taken (i.e., one data sample every
25 milliseconds) for analysis by the Controller
Assembly. The sampling frequency of 40 Hertz
(Hz) was chosen to reduce normal mode noise
(at 60 Hz).

After each point on the chromatograph signal is

sampled, the resulting number is stored for
processing in a buffer area of the Controller
Assembly memory. During the analysis, only
the last 256 data points are available for
processing.

Because the data analysis is done as the signal

is sampled (in real-time), only a limited
number of past data samples is required to
analyze any signal.

As a part of the data acquisition process,

groups of incoming data samples are averaged
together before the result is stored for
processing. Non-overlapping groups of N
samples are averaged and stored, and thus
reduce the effective incoming data rate to 40/N
samples per second. For example, if N = 5, then
a total of 40/5 or 6 (averaged) data samples are
stored every second.

The value for the variable N is determined by

the selection of a Peak Width parameter (PW).
The relationship is

N = PW

where PW is given in seconds. Allowable values

of N are 1 to 63; this range corresponds to PW
values of 2 to 63 seconds.

Data Acquisition SEPTEMBER 2007

 INTRODUCTION 1-23
Model 700

The variable N is known as the integration

factor. This term is used because N determines
how many points are averaged, or integrated,
to form a single value. The integration of data
upon input, before storing, serves two
purposes:

The statistical noise on the input signal is

reduced by the square root of N. In the case
of N = 4, a noise reduction of two would be
realized.
The integration factor controls the
bandwidth of the chromatograph signal. It
is necessary to match the bandwidth of the
input signal to that of the analysis
algorithms in the Controller Assembly. This
prevents small, short-duration
perturbations from being recognized as true
peaks by the program. It is therefore
important to choose a Peak Width that
corresponds to the narrowest peak in the
group under consideration.

1.4.6 Peak Detection

For normal area or peak height concentration

evaluation, the determination of a peak's start
point and end point is automatic. The manual
The Controller Assembly determination of start and end points is used
software assumes that a only for area calculations in the Forced
region of signal quiescence
and stability will exist.
Integration mode. Automatic determination of
peak onset or start is initiated whenever
Integrate Inhibit is turned off. Analysis is
started in a region of signal quiescence and
stability, such that the signal level and activity
can be considered as baseline values.

SEPTEMBER 2007 Peak Detection

 1-24 INTRODUCTION
Model 700

Having initiated a peak search by turning

Integrate Inhibit off, the Controller Assembly
performs a point by point examination of the
signal slope. This is achieved by using a digital
slope detection filter, a combination low pass
filter and differentiator. The output is
continually compared to a user-defined system
constant called Slope Sensitivity. A default
value of 8 is assumed if no entry is made.
Lower values make peak onset detection more
sensitive, and higher values make detection
less sensitive. Higher values (20 to 100) would
be appropriate for noisy signals, e.g. high
amplifier gain.

Onset is defined where the detector output

exceeds the baseline constant, but peak
termination is defined where the detector
output is less than the same constant.

Sequences of fused peaks are also

automatically handled. This is done by testing
each termination point to see if the region
immediately following it satisfies the criteria of
a baseline. A baseline region must have a slope
detector value less than the magnitude of the
baseline constant for a number of sequential
points. When a baseline region is found, this
terminates a sequence of peaks.

A zero reference line for peak height and area

determination is established by extending a
line from the point of the onset of the peak
sequence to the point of the termination. The
values of these two points are found by
averaging the four integrated points just prior
to the onset point and just after the
termination points, respectively.

Peak Detection SEPTEMBER 2007

 INTRODUCTION 1-25
Model 700

The zero reference line will, in general, be non-

horizontal, and thus compensates for any
linear drift in the system from the time the
peak sequence starts until it ends.

In a single peak situation, peak area is the area

of the component peak between the curve and
the zero reference line. The peak height is the
distance from the zero reference line to the
maximum point on the component curve. The
value and location of the maximum point is
determined from quadratic interpolation
through the three highest points at the peak of
the discrete valued curve stored in the
Controller Assembly.

For fused peak sequences, this interpolation

technique is used both for peaks, as well as,
valleys (minimum points). In the latter case,
lines are dropped from the interpolated valley
points to the zero reference line to partition the
fused peak areas into individual peaks.

The use of quadratic interpolation improves

both area and height calculation accuracy and
eliminates the effects of variations in the
integration factor on these calculations.

For calibration, the Controller Assembly may

average several analyses of the calibration
stream.

1.5.1 Conc Analysis - Response Factor

Concentration calculations require a unique

response factor for each component in an
analysis. These response factors may be
manually entered by an operator or determined
automatically by the system through
calibration procedures (with a calibration gas
mixture that has known concentrations).

The response factor calculation, using the

external standard, is:

Area n Ht n
ARF n = --------------- or HRF n = -----------
Cal n Cal n

where

ARFn area response factor for component n in area

per mole percent

Arean area associated with component n in calibra-

tion gas

Caln amount of component n in mole percent in

calibration gas

Htn peak height associated with component n

mole percent in calibration gas

HRFn peak height response factor for component n

Basic Analysis Computations SEPTEMBER 2007

 INTRODUCTION 1-27
Model 700

Calculated response factors are stored by the

Controller Assembly for use in the
concentration calculations, and are printed out
in the configuration and calibration reports.

Average response factor is calculated as

follows:

where

RFAVGn area or height average response factor for

component n

RFi area or height average response factor for

component n from the calibration run

k number of calibration runs used to

calculate the response factors

The percent deviation of new RF averages from

old RF average is calculated in the following
manner:

RF new RF old
deviation = ----------------------------------- 100

where the absolute value of percent deviation

has been previously entered by the operator.

1.5.2 Conc Calc - Mole Percentage

(without Normalization)

Once response factors have been determined by

the Controller Assembly or entered by the
operator, component concentrations are
determined for each analysis by using the
following equations:

Area n Ht n
CONC n = --------------- or CONC n = --------------
ARF n HRF n

where

ARFn area response factor for component n in

area per mole percent

Arean area associated with component n in

unknown sample

CONCn concentration of component n in mole

percent

Htn peak height associated with component n

mole percent in unknown sample

HRFn peak height response factor for component

Component concentrations may be input

through analog inputs 1 to 4 or may be fixed. If
a fixed value is used, the calibration for that
component is the mole percent that will be used
for all analyses.

1.7 GLOSSARY

Auto Zero

Automatic zeroing of the TCD preamplifier

may be configured to take place at any time
during the analysis when either the component
is not eluting or the baseline is steady.

The Micro-FID is automatically zeroed at each

new analysis run and can be configured to take
place anytime during the analysis when either
the component is not eluting or the baseline is
steady. The TCD is only automatically zeroed
at the start of a new analysis.

Baseline

Signal output when there is only carrier gas

going across the detectors. In a chromatogram
you should only see Baseline when running an
analysis without injecting a sample.

Carrier Gas

The gas used to push the sample through the

system during an analysis. In C6+ analysis we
use Ultra Pure (zero grade) Carrier Gas for the
carrier. This gas is 99.995 percent pure.

Chromatogram

A permanent record of the detector output. A

chromatograph is obtained from a PC
interfaced with the detector output through the
Controller Assembly. A typical chromatogram
displays all component peaks, and gain
changes. It may be viewed in color as it is
processed on a PC VGA display. Tick marks
recorded on the chromatogram by the
Controller Assembly indicate where timed
events take place.

3.1.4 Signal Wiring

Follow these general precautions for field

wiring digital and analog input/output (I/O)
lines:

DANGER TO PERSONNEL AND EQUIPMENT

Observe all precautionary signs posted on the Model
700 enclosure. Applicable to all digital and analog I/O
lines connecting to the GC: Any loop of extra cable
left for service purposes inside the GC housing must
not be placed near any AC power lines.
If this precaution is not followed, the data and control
signals to and from the GC can be adversely affected.

Metal conduit must be used for all process

signal wiring (assuming operation in a
Class 1, Division 1 Explosive Area). Metal
conduit is not required for use in general
purpose areas.
Metal conduit or cable (in compliance with
EN 60079-14) used for process signal wiring
must be grounded at conduit support points
(intermittent grounding of conduit helps
prevent induction of magnetic loops
between the conduit and cable shielding).
All process signal wiring should be a single,
continuous length between field devices and
the GC. If, however, length or conduit runs
require that multiple wiring pulls be made,
the individual conductors must be
interconnected with suitable terminal
blocks.
Use suitable lubrication for wire pulls in
conduit to prevent wire stress.

Signal Wiring SEPTEMBER 2007

 INSTALLATION AND SETUP 3-11
MODEL 700

Use separate conduits for AC voltage and

DC voltage circuits.
Do not place digital or analog I/O lines in
same conduit as AC power circuits.
Use only shielded cable for digital I/O line
connections.
- Ground the shield at only one end.
- Shield-drain wires must not be more
than two AWG sizes smaller than the
conductors for the cable.
When inductive loads (relay coils) are
driven by digital output lines, the inductive
transients must be diode-clamped directly
at the coil.
Any auxiliary equipment wired to the GC
must have its signal common isolated from
earth/chassis ground.

3.1.5 Electrical and Signal Ground

Follow these general precautions for grounding

electrical and signal lines:

For shielded signal conducting cables,

shield-drain wires must not be more than
two AWG sizes smaller than the conductors
for the cable. Shielding is grounded at only
one end.
Metal conduit used for process signal wiring
must be grounded at conduit support points
(intermittent grounding of conduit helps
prevent induction of magnetic loops
between the conduit and cable shielding).

SEPTEMBER 2007 Electrical and Signal Ground

 3-12 INSTALLATION AND SETUP
MODEL 700

A single-point ground (the outside case

ground lug) must be connected to a copper-
clad, 10-foot long, 3/4-inch diameter steel
rod, which is buried, full-length, vertically
into the soil as close to the equipment as is
practical (note: the grounding rod is not
furnished.)

Ground Lug Ground Lug

Inside Lower Outside Lower
Enclosure Enclosure
Figure 3-6 Ground Lug Lower Enclosure

Resistance between the copper-clad steel

ground rod and the earth ground must not
exceed 25 Ohms.
On ATEX certified units, the external
ground lug must be connected to the
customers protective ground system via
AWG 9 (6mm2) ground wire. After the
connection is made, apply a non-acidic
grease to the surface of the external ground
lug to prevent corrosion.

Electrical and Signal Ground SEPTEMBER 2007

 INSTALLATION AND SETUP 3-13
MODEL 700

The equipment-grounding conductors used

between the GC and the copper-clad steel
ground rod must be sized according to the
following specifications:

Length Wire

15 ft. (4.6 m) or less 8 AWG

stranded, insulated copper

15 to 30 ft. (4.6 to 9.1 m) 6 AWG

stranded, insulated copper

30 to 100 ft. (9.1 to 30.5 m) 4 AWG

stranded, insulated copper

All interior enclosure equipment-grounding

conductors must be protected by metal
conduit.
External equipment, such as data printers,
that are connected to the GC should be
powered via isolation transformers to
minimize the ground loops caused by the
internally shared safety and chassis
grounds.

3.1.6 Electrical Conduit

Follow these general precautions for conduit

installation:

Conduit cutoffs must be square. Cutoffs

must be made by a cold cutting tool,
hacksaw, or by some other approved means
that does not deform the conduit ends or
leave sharp edges.
All conduit fitting-threads, including
factory-cut threads, must be coated with a
metal-bearing conducting grease, such as
Crouse-Hinds STL or equivalent, prior to
assembly.

SEPTEMBER 2007 Electrical Conduit

 3-14 INSTALLATION AND SETUP
MODEL 700

Temporarily cap the ends of all conduit runs

immediately after installation to prevent
accumulation of water, dirt, or other
contaminants. If necessary, swab out
conduits prior to installing the conductors.
Install drain fittings at the lowest point in
the conduit run; install seals at the point of
entry to the GC explosion-proof housing to
prevent vapor passage and accumulation of
moisture.
Use liquid-tight conduit fittings, such as
Myers Scru-tite or similar, for conduits
exposed to moisture.

When conduit is installed in hazardous areas

(e.g., areas classified as NEC Class I, Division
1, Groups B, C, and D), follow these general
precautions for conduit installation:

DANGER TO PERSONNEL AND EQUIPMENT

Observe all precautionary signs posted on the
equipment. Consult your company policies and
procedures and other applicable requirements
documents to determine wiring and installation
practices that are appropriate for hazardous areas.
Failure to do so may result in injury or death to
personnel or cause damage to the equipment.

All conduit runs must have a fitting, which

contains explosion-proof sealing (potting)
located within 18 inches from the conduit
entrance to the explosion-proof housing.
The conduit installation must be vapor
tight, with threaded hub fittings, sealed
conduit joints and gaskets on covers, or
other approved vapor-tight conduit fittings.

system.

SEPTEMBER 2007 Preparing for Serial Connections

 3-38 INSTALLATION AND SETUP
MODEL 700

Before connecting a PC to the Model 700,

determine the following:

1. What serial ports are available at the PC?

When you select one, consider these points:
Standard PC serial ports are type
RS-232.
Usually there are two external serial
port jacks on a PC, located on the rear
panel. Most often, they are either DB-9
or DB-25 male (see below). Model 700 software
upgrades may be installed
via any available Com Port.

PC serial ports can be used by other

peripheral equipment attached to the
PC, such as a printer, mouse, or modem,
etc.
To determine which PC serial ports are
already being used by other equipment
and which port can be used for
connecting to the GC, note existing serial
connections, refer to your PC user
manual, and use diagnostic software
(such as Norton Utilities).
2. What serial ports are available at the GC?
The Model 700 without the Micro-FID
comes equipped with three serial ports
(standard), unless the customer needs a LOI
Interface connection, then only two com
ports are standard. The installation of the
optional Com4A board (with or without a

4.2 TROUBLESHOOTING AND REPAIR CONCEPT

The most efficient method for maintaining and

repairing the Model 700 GC system is a
component-replacement concept that allows
you to return the system to operation as
quickly as possible. Sources of trouble, such as
printed-circuit assemblies, valves, etc., are
identified during troubleshooting test
procedures and are replaced at the lowest level
practical with units in known working order.
The defective components are then either
repaired in the field or returned to
Measurement Services for repair or
replacement.

4.3 ROUTINE MAINTENANCE

The Model 700 GC system will perform

accurately for long periods with very little
attention (except for maintaining the Carrier
Gas cylinders). A bimonthly record of certain
parameters will assist greatly in assuring that
your Model 700 is operating to specifications.
The maintenance checklist should be filled out
bimonthly, dated, and kept on file for access by
maintenance technicians as necessary (see
Table 4-2).This gives you a historical record of
the operation of your Model 700, enables a
maintenance technician to schedule
replacement of gas cylinders at a convenient
time, and allows quick troubleshooting and
repair when it becomes necessary.

Troubleshooting and Repair Concept SEPTEMBER 2007

 MAINTENANCE AND TROUBLESHOOTINGTABLE OF CONTENTS 4-3
Model 700

A chromatogram, a Configuration Report, and

a Raw Data Report should also be made and
filed with the checklist, furnishing a positive
dated record of the Model 700. The
chromatogram and reports can also be
compared to the chromatograms and reports
run during the troubleshooting process.

4.3.1 Bimonthly Maintenance Checklist

Copy the sample maintenance checklist as

necessary for your files (see Table 4-2). If you
have a problem, please complete the checklist
and reports, and have the results available
when calling Measurement Services with a
problem. Also have the Sales Order number.
The Sales Order number can be found on the
nameplate located on the left side wall of the
upper housing of the Model 700. The
chromatograms and reports archived when
your Model 700 left the factory are filed by this
number.

The explosion-proof housing should not be opened
when the unit is exposed to an explosive environment.
If access to the explosion-proof housing is required,
precautions must be taken to ensure that an explosive
environment is not present.
Failure to do so may result in injury or death to
personnel or cause damage to the equipment.

The Model 700 electrical/electronic components

are located in the upper and lower explosion-
proof housings. All of the electrical/electronic

Baseline Drift

To ensure that the baseline is not drifting,

compare the baseline upsets caused by valve
actuations with those of the spectrum
chromatogram provided with the Operational
Parameters Sheet.

Ensure that no evidence of component elutions

is present when sample is not being injected.

If differences exist between the two spectrum

chromatograms, the problem may be due to one
or more of the following:

programming of events
contamination of the multivalve sealing
diaphragms by foreign matter
improperly adjusted flows
leaks in the carrier system
column deterioration due to liquid
contamination from a sample
mis-identifying peaks

A noisy baseline can be caused by carrier leaks,

an electronic failure in the preamplifier, a
faulty power supply, or defective thermistors in
the detector. If the baseline is still noisy after
correcting for leaks, perform the Detector
Bridge Balance procedure (see Section 4.9)
before replacing the detector thermistors or the
preamplifier board.

4.7.3 Plugged Lines, Columns, or Valves

To ensure that lines, columns, and valves are

not plugged, check the gas flow at valve ports.
For a reference, use the flow diagram in the
drawing package, and remember these points
about flow diagrams:

Port-to-port flow paths are indicated by

solid or dashed lines.
A dashed line indicates flow direction when
the valve is ON, that is, energized.
A solid line indicates flow direction when
the valve is OFF, i.e., not energized.
A combination of solid and dashed lines
indicates a constant flow path regardless of
the ON/OFF state of the valve.

The analog outputs can be calibrated and or

adjusted via the MON2000 software. However,
these outputs should be measured with a good
digital meter upon initial installation at zero
scale and full scale. Then the span can be set
with MON2000 software so that it represents
values from zero to 100 percent of the user-
defined units in use.

Nominally, calibration is made within a range

of 4-20 milliamperes (mA) output from each
analog channel. However, zero scale
calibrations can be set with 0 mA output, and
full scale calibration can be set with up to 22.5
mA output. If there is reason to suspect that
the span on any particular channel might be off
after a period of time and heavy use, then the
analog output for that channel should be
recalibrated.

4.13.2 Analog Output Adjustment

The initial analog output adjustment will be set

at the factory, before shipment, at standard
values (4-20 mA). It may be necessary to check
and/or adjust these values depending on output
cabling/impedance. The adjustment may
require two persons if the units are some
distance apart. It will require a good digital
meter to check the zero and full scale values at
the receiving end. The scale or span value can
be adjusted by a PC with the Model 700 when
the values are known at the receiving end.

It is possible to calibrate the analog outputs

using different engineering units, volts and
percentages. For examples and detailed
instructions, refer to the MON2000 Software
for Gas Chromatographs Users Manual
(P/N 3-9000-522).

4.14 DISCRETE DIGITAL INPUTS/OUTPUTS

For instructions on connecting digital inputs

and outputs to the GC Field Termination
Boards, see Section 3.4.7 for more details.

An external loopback test circuit can be built

for troubleshooting the Model 700 digital input/
output operation.

4.15 RECOMMENDED SPARE PARTS

See Appendix D for the lists of recommended

spare parts for approximately one year of
maintenance. The quantities represent the
number of spares to cover most contingencies
at facilities where GC systems are in operation.

Measurement Services offers service and repair

service contracts that make maintaining most
spares for the GC system unnecessary. Details
regarding service contracts may be obtained by
contacting Measurement Services at the
address or telephone number on the Customer
Repair Report in the back of this manual.

(P/N 3-9000-522) for BOS
upgrade procedures.
BOS provides the basic resources and
interfaces to run the user's tasks. Unlike DOS
or Windows or Linux, since BOS is an
embedded real-time multi-tasking preemptive
operating system, there is no direct user level
interface to it. If a BOS upgrade is required to
your system, refer to the MON2000 Software
for Gas Chromatographs User Manual (P/N 3-
9000-522) for additional BOS information.

4.16.2 Applications

The GC application, which runs under BOS,

utilizes the tools provided by BOS to perform
the desired gas chromatograph functions for
the user. There are different applications to
provide for different gas chromatographic
needs. To load a new application or to upgrade
an existing application refer to the MON2000
Software for Gas Chromatographs User
Manual (P/N 3-9000-522) for details.

To make an RS-232 serial connection between

one of the DB 9-pin serial ports of the GC, and
a PC with DB 9-pin serial port, use a straight-
through serial cable, terminated as DB 9-pin

assignments are identical to those found on a
typical DB 9-pin serial port of an IBM PC.

The straight-through serial cable can be

obtained from most computer products

3. Open cylinder valve for Carrier Cylinder 1.
The pressure indicator will read the
cylinder pressure.
4. Open the shut-off valve attached to the
carrier regulator.
5. Regulate pressure out of the cylinder to 20
psig, then close the cylinder valve.
6. Open V-1 (bleed valve) and let the carrier
gas bleed to atmosphere until both gauges
read 0 psig, then close V-1.
7. Repeat Steps 4 and 5 two more times to
purge the line to V-2.
8. Purge the line to V-3 by repeating Steps 2
through 6; but this time, use bleed valve V-4
and Carrier Cylinder 2.
9. With valves 1-4 closed, open both cylinder
valves and regulate both carriers to
approximately 10 psig.
10. Open V-2 and V-3 simultaneously, then
turn both cylinder valves off and let the
carrier gasses bleed through the line to the
Analyzer until all gauges read 0 psig.
11. Repeat steps (8) and (9) two more times to
purge line to Analyzer.
12. Close V-3, leave V-2 open.

C.4 CALIBRATION GAS

The calibration gas used for BTU analysis

should be blended of gases specified as Primary
Standards. Primary Standard gases are
blended using weights that are traceable to the
National Institute of Standards and
Technology (N.I.S.T). For other applications,
the calibration gas should be blended to the
specifications detailed in the analyzers
Application Data Sheets.

The calibration gas should not have any

component that could drop out at the coldest
temperature to which the gas will be subjected.
A typical blend for a temperature of zero
degrees Fahrenheit is listed in the following
table (Table C-1). No dropout will occur in this
calibration gas if it is blended at a pressure
below 250 psig.

E.2.1 Navigating the Screen

LOI screens have several functions. They can

display data for review; they can display data
for editing; and they can be used to initiate
activities.

Use the Up and Down arrow keys to navigate

between fields or controls within each drop
down menu. Pressing the Down arrow key
while focus is on the last field of a drop down
menu moves the focus to the first field on a
screen. Alternatively, pressing the Up arrow

Navigating the Screen SEPTEMBER 2007

 LOCAL OPERATOR INTERFACE E-5

key while focus is on the first field of the drop

down menu causes the focus to move to the last
field.

Within any given screen, the function of the

Enter key depends upon the context. It can be
used to save changes or to initiate an action.

Pressing the Exit key closes the currently

open screen and discards any changes made to
the fields or controls on the screen.

The F1 and F2 keys are context dependent. A

one-word desrciption of the function of each of
these keys displays in a green prompt box
directly under the key in the title bar of the top-
level full-sized screen. In some cases, F1 acts
as a toggle between scrolling either a line or a
page at a time. When this is true, the currently
selected option (LN or PG) displays with a
green background and black text, while the
non-selected option displays with a black
background and green text. The F2 key, when
MAIN is displayed in its prompt box, closes all
screens that were opened through the Main
Menu and goes back to the Main Menu. If edits
were made, the operator will be prompted to
save or cancel the changes, or to abort the
original close request.

When a key is pressed, the word LED appears

in green in the upper left corner of the top-level
full-sized screen to acknowledge that the key
closure was recognized.

E.2.2 Editing Numeric Data

value of each digit. The possible values are 1,

2, 3, 4, 5, 6, 7, 8, 9, 0, - (minus), . (period), E,
and ' ' (space).

The - (minus) value is available for signed

numbers.

The . (period) and E values are available for

floating-point numbers, except for Retention
Times and Timed Event values.

The ' ' (space) value is available for Retention

Times and Timed Event values, and for the
most significant digit in the "tens" position or
greater.

The Down arrow key moves backward in the list

from the current value of the selected digit.

The Up arrow key moves forward in the list

from the current value of the selected digit.

The F1 (BACKSP) key acts as a backspace,

except when editing Retention Times and
Timed Event values. It deletes the digit
immediately to the left of the current position.

The Enter key validates and saves the entry.

The Exit key cancels any changes and restores

the previous value.
