1.2 INTRODUCTION
The Emerson Process Management Model 1000 Gas Chromatograph is a high-speed GC system that is factory engineered to meet specific field application requirements based on stream composition and the anticipated concentration of the components of interest. The GC System typically consists of three major components, the Analyzer Assembly, the GC Controller, and the Sample Conditioning System:
Analyzer Assembly (Model 1000 Series) - Located near the sample tap in a freeze-protected
shelter. The Analyzer includes GC columns, detectors, preamplifier, stream switching valves, and solenoids.
GC Controller - Located either integrally in the upper enclosure or made for mounting on a
standard 19-inch rack in a nonhazardous protected area, with or without a built-in keyboard and LCD. The GC Controller includes electronics and ports for signal processing, instrument control, data storage, personal computer (PC) interface, and telecommunications.
Rack Mount - Suitable for use in a nonhazardous environment.
Sample Conditioning System (SCS) - Located between the process stream and the Analyzer
sample inlet, usually mounted on the lower portion of the Analyzer stand. The standard configuration SCS includes a mounting plate, block (or shutoff) valves, and filters. Optionally, the SCS can be configured with Genie bypass filters, liquid shut-off valves, and
®
optional solenoids for stream switching; all of which can be enclosed in an electric (heat tape design) oven.
DESCRIPTION
1-3
SEP 2005 MODEL 1000
In its standard configuration, the Model 1000 series Analyzer can handle up to five streams: typically, four for sample and one for calibration. With an optional stream switch assembly added, the GC System can switch up to twelve streams, maximum.
The GC Controller, is designed to be operated primarily from a personal computer (PC) running the MON2000 software package. This provides the user with the greatest capability, ease-of-use, and flexibility. One PC running MON2000 can connect with up to 32 chromatographs (via RS-485 serial communications links). The PC is used to display analysis chromatograms and reports, which can then be stored to files on the PC hard drive, or printed from either the PC's printer port or the GC Controller's printer port.
Also, each individual GC Controller can be operated from its built-in keyboard and LCD (if installed in that configuration); however, this method offers more limited functions. Display of the chromatograms on the LCD is accomplished in scrolling strip chart fashion.
Since neither the PC nor a normal printer can be placed in a hazardous area, serial port and Modbus communications links are provided for connecting the GC System to the PC, other computers, printers, chromatographs, and Controllers.

1.3 FUNCTIONAL DESCRIPTION
A functional block diagram of a typical GC System installation is shown in Figure 1-1. 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 sample conditioning system where it is filtered or otherwise conditioned. After conditioning, the sample flows to the Analyzer for separation and detection of the components of the gas.
The chromatographic separation of the sample gas into its components is accomplished in the Analyzer in the following manner. A precise volume of sample gas is injected into one of the unit's analytical columns. The column contains a stationary phase (packing) that is either an active solid (adsorption partitioning) or an inert solid support that is coated with a liquid phase (absorption partitioning). The gas sample is moved through the column by means of a mobile phase (carrier gas). Selective retardation of the components of the sample takes place in the column that causes each component to move through the column at a different rate. This action separates the sample into its constituent components.
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 component. Outputs from the Analyzer detectors are amplified in the Analyzer electronics, then transmitted to the GC Controller for further processing. (See also, Section 1.6, "Theory of Operation.")
Output from the GC Controller is normally displayed on a remotely located personal computer (PC) or a printer. Connection between the GC Controller and the PC can be accomplished via a direct serial line or via the Modbus-compatible communication interface.
Multiple chromatograms may be displayed on the PC monitor, and compared or contrasted with separate color schemes. This allows a stored chromatogram to be compared/contrasted with a current or another stored chromatogram. This could be of great assistance when changing parameters or isolating a problem.
Use of a PC for configuration and troubleshooting procedures is essential in most instances. (Basic operations can also be performed from a keyboard and liquid crystal display that are built into certain versions of the GC Controller.) The PC may be remotely connected via telephone, radio or satellite communications. Once installed and configured, the GC System can operate independently for long periods of time.

1.6 THEORY OF OPERATION
See Section 1.7, the “Glossary” section of this manual, for definitions of some of the terminology used in the following explanations.
1.6.1 Analyzer Detector
The Analyzer detector subsystem 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. A schematic diagram of the thermal conductivity detector is shown in Figure 1-2.
DESCRIPTION
Figure 1-2. Schematic Diagram of Analyzer Detector Bridge
1-11
SEP 2005 MODEL 1000
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. 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 1-3 illustrates the change in detector electrical output during elution of a component.
Figure 1-3. Detector output during component elution
1. Detector bridge balanced.
2. First component begins to elute from column and to be sensed by the measurement thermistor.
3. Peak concentration of first component.
4. Second component begins to elute from column and to be sensed by the measurement thermistor.
5. Peak concentration of second component.
In addition to amplifying the differential signal developed between the detector's two thermistors, the preamplifier also supplies drive current to the detector bridge. The preamplifier also supplies drive current to the detector bridge. The voltage signal is converted to a 4 to 20-milliamp (mA) current loop for transmission to the GC Controller. 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. The signals from the preamplifier are sent to the GC Controller for computation, recording on a printer, or viewing on a PC monitor or LCD.
1-12
DESCRIPTION
MODEL 1000 SEP 2005
1.6.2. Data Acquisition
Every second, exactly 40 equi-spaced data samples are taken for analysis by the GC Controller (i.e., once every 25 milliseconds). Each data sample, after having been precision-amplified, is subjected to a twelve bit analog to digital (A/D) conversion. The sampling frequency of 40 Hertz (Hz) was chosen to reduce 60 Hz normal mode noise.
After each point on the chromatograph signal is sampled, the resulting number is stored in a buffer area in the GC Controller’s memory for processing. 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 to the Controller’s memory for processing. Non-overlapping groups of N samples are averaged and stored, and thus reduce the effective incoming data rate to 40/N samples/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 seconds,
where PW is given in seconds. All the various details in the analysis process are independent of the value of N. Allowable values of N are 1 to 63, which corresponds to values of PW from 2 to 63 seconds.
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. First, 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. Secondly, 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 GC Controller. This prevents small, short duration perturbations from being recognized as true peaks by the program. It is therefore important to choose a Peak Width corresponding to the narrowest peak in a group under consideration.
DESCRIPTION
1-13
SEP 2005 MODEL 1000
1.6.3 Peak Detection
For normal area or peak height concentration evaluation, the determination of a peak's start, peak point, and end is automatic. The manual determination of start and end points is used only for area calculations in the Forced 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. It is important that this be the case because the assumption is made by the GC Controller software.
Having initiated a peak search by turning Inhibit off, the GC Controller performs a point by point examination of the signal slope. This is achieved by using a digital slope detection filter which is a combination low pass filter and differentiator. The output of this detector is constantly compared to a system constant entered by the operator 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.
Peak termination is determined by the same application of this detector to the signal, but in the reverse sense. Onset is defined where the detector output exceeds the baseline constant, but termination is defined subsequently 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. 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.
1-14
DESCRIPTION
MODEL 1000 SEP 2005
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 GC Controller.
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 GC Controller may average several analyses of the calibration stream.

1.6.4 Basic Analysis Computations
Two basic analysis algorithms are included in the GC Controller. These are:
Area Analysis - Calculates area under component peak
Peak Height Analysis - Measures height of component peak
Concentration Analysis by Using Response Factor

EQUIPMENT DESCRIPTION

SEP 2005 MODEL 1000
2.1 SAMPLING SYSTEM
A well designed, properly adjusted sampling system is essential to optimum performance of any gas chromatograph. If a good sample is not obtained for analysis, the whole purpose of the system is compromised.
The purpose of the sample handling system is to transfer a conditioned fluid sample that is compatible with gas chromatography requirements.
The Sample Conditioning System (SCS) is located between the process stream and the Analyzer, and is usually mounted on the lower portion of the Analyzer stand. It serves these purposes:
- Extracts final sample from the fast loop,
- Performs final filtration,
- Performs stream switching for a multi-stream Analyzer, and
- Adjusts the final pressure, temperature, and flow control on the selected sample
flowing to the sample valve.
The following points should be considered in selecting and installing a sampling system:
- Sample Paint
- Sample Volume and Flow Rate
- Sample Conditioning
- Contamination Precautions
- Valving
- Calibration Gas
2.1.1 Sampling Point Location
Gas samples must be representative of the process stream and must be taken from a location where stratification or separation of components does not occur. The sampling point should be as close as feasible to the Analyzer.
2.1.2 Sample Volume and Flow Rate
An adequate response time for sample analysis requires that sample volumes should generally be as small as possible, and the flow rate between the sampling point and the Analyzer should be as high as possible, consistent with accuracy. To minimize time lag and to prevent back diffusion, dryers and filters in the sampling line should be as small as possible. When long sampling lines cannot be avoided, flow velocity in the line can be increased by decreasing the downstream pressure.
2-2
EQUIPMENT DESCRIPTION
MODEL 1000 SEP 2005
Typically, pressure is reduced at the sample point with a pressure regulating sample probe. The input pressure to the Analyzer can be adjusted between 10 and 20 pounds per square inch, gauge (psig). Reducing the pressure at the sample point avoids the problem of heavy liquid dropout in the sample line during cold weather. The flow rate in the sample line is set at 50 cubic centimeters (cc) per minute with the restrictor valve at the Analyzer.
The Model 1000 is capable of accepting liquid phase samples also. In this case, the pressure is regulated by means of a back pressure regulator located on the SCS mounting plate. If the stream is at ambient pressure or under slight vacuum, an educator or pump may be used to force sample through the sample loop. In this situation, sample shut-off technique with equalizing coil is employed to ensure consistency of the sample volume.
Use this general rule to approximate sample lag time caused by the length of sample line. Sample line constructed of 1/8-inch tubing contains approximately 1 cc of volume per foot. Therefore, with a flow rate of 50 cc per minute, the lag time of the sample between the sample point and the Analyzer is calculated by dividing the length of the line (in feet) by 50. For example, the sample in a 100 foot sample line will take 2 minutes to travel the length of the line.
2.1.3 Sample Conditioning
Sample systems should contain at least one filter to remove solid particles from the sample stream. Most applications require fine-element filters upstream of the Analyzer.
2.1.4 Contamination Precautions
Several precautions are recommended to minimize the possibility of contaminating samples. Except in special applications, filters should be of either the ceramic or the porous metallic type to avoid the absorption losses characteristic of fiber or paper filters. Pressure regulators and flow controllers containing cork or felt filters or absorbent diaphragms should not be used. Sampling lines for noncorrosive streams should be stainless steel tubing and must be clean and free of grease. Lines must be pressure tight to prevent diffusion of moisture or atmospheric gases into the sample. Pipe threads should be dressed only with Teflon tape on pipe threads and never with pipe thread compounds (dope).
EQUIPMENT DESCRIPTION
2-3
SEP 2005 MODEL 1000
2.1.5 Valving
A block valve should be installed immediately downstream of the sample takeoff point to permit shutdown of the system for maintenance. Block valves should be either gate valves or cocks of the proper material and packing, and should be rated for the process line pressure. Tight seating of all connections is essential.
2.1.6 Calibration Gas
A calibration gas used for Process analysis should be blended to Primary Standards. Primary Standards are blended using weights that are traceable to the National Bureau of Standards (NBS). If the calibration standard is a gas, the standard 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 (0°F) is listed in the following table. No dropout will occur in this calibration gas if it is blended at a pressure below 250 psig.

SEP 2005 MODEL 1000
2.2.2.1 Primary Plate
The primary plate contains precisely machined internal passages that enter and exit the valve at top ports, each of which is connected to the top and/or bottom of the plate within the valve. The primary plate, which is the only metallic element that comes in contact with the sample, is isolated from the remainder of the valve by specially formulated diaphragms.
GC valve should be torqued to 30 Ft. lbs.
2.2.2.2 Actuating Subassemblies
Below the primary plate, pistons are operated by pneumatic pressure applied to actuating diaphragms through ports in the base plate.
2.2.2.3 Operation
When pneumatic pressure is applied to the actuating diaphragms, the pistons are actuated, thus forcing the sealing diaphragm against the primary plate. This closes the passages that are connected at the bottom of the plate. When pressure is removed, the pistons are free to move, and flow is resumed through the passages.
2.2.3 Detector Subsystem
The operation of the Analyzer detector subsystem was previously discussed in the "Theory of Operation" section of this manual.
2.2.4 Analyzer Preamplifier Unit
The electrical output from the detector is amplified by the Analyzer preamplifier unit. The preamplifier also supplies drive current to the detector bridge. The voltage signal is converted to a 4 to 20-milliamp (mA) current loop for transmission to the GC Controller. The signal is proportional to the concentration of a component detected in the gas sample. The preamplifier provides four different gain channels and compensates for baseline drift. The signals from the preamplifier are then sent to the GC Controller, where they provide the basis for analysis computations and a chromatographic trace, or chromatogram.

2.3 CONTROLLER
The GC Controller is a microprocessor-based device that provides the GC System with highly accurate timing, precision calculations, pertinent report generation, and an interface with other devices. The Controller provides both analog outputs and a direct digital link with output devices through RS-232C, RS-422, or RS-485 ports. Volatile portions of the program are protected by a lithium battery backup if power is lost or turned off at the unit.
The GC Controller can be linked directly to a PC by serial connection, by a telecommunication link that uses Modbus protocol, or ethernet connection. This provides the preferred method for operating the GC System. Limited control of the GC System is also possible through a built-in keypad and display, which are optional components of the purged, hazardous environment GC Controller package. The local alphanumeric keypad and display allow for maintenance and minor adjustments in a hazardous environment.

EQUIPMENT DESCRIPTION
2-11
SEP 2005 MODEL 1000
For operating a printer (in a nonhazardous area) at the GC Controller site, a DB-25 parallel port is available on the GC Controller's Terminal Board (TB) for field wiring.
For connecting a PC to the GC Controller at the GC Controller site (for setup, operation, or maintenance in a nonhazardous area), a DB-9 serial port connector is available on the Controller's front panel.
The STD-Bus Card Cage inside the GC Controller is equipped with two cards. Card slots are preassigned so that cables can be consistently routed. However, the COM4A Board, the Modem Board and the Ethernet Board may be piggy-backed in any order on the CPU Board. If the Radicom modem is used, it must be the top board in the card cage assembly.
An optional stream switching assembly (with either AC or DC solenoids) can be controlled by the GC Controller, allowing for switching up to 12 streams.
2.3.1.1 Analog Inputs and Outputs
The GC Controller can accommodate eight fully differential analog 4 to 20 mA input signals. Four of the analog inputs are used by the associated Analyzer, and they are filtered with transient protection. The additional four input ports provide the ability to accept signals from other Analyzers, so that the analytical report of the chromatograph can include other information on the gas stream, such as water or sulphur content. Transient protection and shield terminations are available for these inputs.
There is capability for a maximum of ten analog outputs. Two analog outputs are available as standard components of the Controller; the other eight analog outputs are optional. All ten analog outputs are current type: 4-20 mA, not isolated. Also, all ten analog outputs can be calibrated by the MON2000 software.

EQUIPMENT DESCRIPTION
MODEL 1000 SEP 2005
2.3.1.2 Digital Inputs and Outputs
The Controller has the capability of sixteen digital inputs used as follows:
5 - to read a Modbus address, as defined by DIP switch positions. 2 - to indicate presence and type of front panel as defined by switch positions 1 - Spare 1 - temperature sensor input to shut off LCD backlight 1 - GC alarm, optically isolated, with transient protection 5 - stream flow alarms, optically isolated, with transient protection 1 - photocell detector, front panel backlight (night on, day off)
The Controller has the capability of 22 digital outputs used as follows:
6 - Analyzer control 8 - driver outputs for DC air solenoids (stream switching, 12 total streams) 5 - alarms, optically isolated, with transient protection 3 - front panel indicators (green, yellow, red)
The digital transient-protected discrete outputs can furnish up to 50 mA. If more current is required (up to 0.5A), a special transient protection plug-in module should be installed (see Appendix C, this manual, for transient protection module details).
2.3.1.3 Communications
There are 3 to 8 communication ports externally available (depending on options package selected). The communications ports can use either RS-232, RS-422, or RS-485 protocol, selected by Data Interface Chips via the CPU Board. The communications ports on these boards are normally configured at the factory, as specified by the customer's communications requirements. The Modbus switch positions are also normally set at the factory as specified by the customer. If any changes need to be made in the field, refer to the drawings in the rear of this manual.
EQUIPMENT DESCRIPTION
2-13
SEP 2005 MODEL 1000
2.3.1.4 Driver Outputs
The GC Controller has eight stream switch outputs, 120 mA continuous current, which can be used to control optional AC or DC solenoid switch boards. This increases stream switch capability from the standard capability of four gas streams and 1 calibration gas (CAL) system to a maximum capability of twelve streams.
The optional stream switching assembly (AC or DC solenoid systems) has provisions for eight stream routes, but adding this option has the net effect of adding only seven more stream routes to the standard stream capacity of five (thus giving a total stream capacity of twelve). The reason is, when the optional stream switch assembly is installed, one of the Analyzer’s standard five stream routes becomes dedicated to the optional stream switch assembly.
2.3.1.5 General Controller Specifications
a. Power requirements (without current outputs): 63.25VA typical for basic instrument
b. Voltage options:
1. 115 VAC ±15 percent, 50 to 60 Hz @ 0.33 A

2.3.2 Optional Keypad and Display
A keypad and liquid crystal display (LCD), optionally built into the enclosure's front panel, are available for the purged and rack mount versions of the GC Controller. The built-in keypad and LCD are especially useful for the purged version. They permit onsite display, control, and data entry at a GC Controller that is situated in a hazardous environment. Note, however, that the control capabilities offered through the built-in keypad and LCD are more limited than those available through a PC connected to the GC Controller.
For details on using the Controller's built-in keypad and LCD, see Section 4, this manual.
2.3.2.1 Keypad
The front panel keypad is an 18-Key data/function entry device arranged so that the ALT key causes the lower key markings to be displayed/entered. The designations marked on the top of the keys will be displayed/entered when the ALT key is not pressed.
2.3.2.2 Display
The Controller display, measuring 5.5 x 2 inches, is capable of 8 lines by 41 characters. It is certified for use with a purged NEMA 4X, Class C and D, enclosure. The display is capable of producing the complete alphabet and numbers from the keypad. The video display on the Controller may show a truncated (or curtailed) version of the displays available at the PC. Although the keypad/display located at the Controller site can do many of the functions that the PC software can do remotely, any extensive operations are more conveniently performed through MON2000 on the larger screen and keypad of a PC. A few adjustments will be more conveniently accomplished at the Controller site.
2.3.3 Alarm Specifications
In the GC Controller there is the capacity for 36 alarms. There are also operator defined alarms. Some of the alarms are active only if the configuration of the Controller requires the function that is associated with those alarms. Active alarms are shown in the ALARMS menu.

2.3.3.1 Status Indicators
Three colored LED status indicators are located at the side of the display on the front panel. The indicators are arranged from yellow, green, and red. When illuminated, the LED status indicators signify the following:
- Yellow LED: When illuminated, the Yellow LED indicates that an out-of-tolerance value or an alarm condition was entered into the Controller memory for printout with the analysis. The Controller memory retains the alarm for printout until the operator clears the alarm(s). This indicator is partially application controlled and may be set at different out-of-tolerance levels with different applications.
- Green LED: When illuminated, the Green LED indicates that the Controller is operating. If the green LED is illuminated and the Controller does not accept changes, a password lockout may have been entered. If a password has been entered, the password must be re-entered before the Controller program can be changed.
- Red LED: When illuminated, the Red LED indicates an out-of-tolerance value or an alarm condition in the RUN mode that requires operator action. Alarm contacts are closed under these conditions. The Red LED is automatically turned off and contacts opened by the Controller at the start of the next analysis.

Follow these general precautions for field wiring digital and analog input/output (I/O) lines:
(1) Metal conduit must be used for all process signal wiring.
(2) Metal conduit used for process signal wiring must be grounded at conduit support points
(grounding the conduit at multiple points helps prevent induction of magnetic loops between the conduit and cable shielding).
»
(3) Use suitable lubrication for wire pulls in conduit to prevent wire stress.
(4) All process signal wiring should be a single, continuous length between field devices and the
GC Controller. If, however, length or conduit runs require that multiple wiring pulls be made, the individual conductors must be interconnected with suitable terminal blocks.
(4) Use separate conduits for AC voltage and DC voltage circuits.
(5) Do not place digital or analog I/O lines in same conduit as A-C power circuits.
(6) Use only shielded cable for digital I/O line connections.
(a) Ground the shield at only one end.
(b) Shield-drain wires must not be more than two AWG sizes smaller than the
conductors for the cable.
INSTALLATION AND SETUP
3-7
SEP 2005 MODEL 1000
(7) When inductive loads (relay coils) are driven by digital output lines, the inductive transients
must be diode clamped directly at the coil.
(8) Any auxiliary equipment wired to the GC Controller must have its signal common isolated
from earth/chassis ground.
Applicable to the digital and analog I/O lines connecting to the GC Controller, including the Analyzer-Controller Interconnect lines: Any loop of extra cable left for service purposes inside the GC Controller purged housing must not be placed near the conduit entry for AC power.
If the above precaution is not followed, the data and control signals to and from the GC Controller can be adversely affected.

Follow these general precautions for conduit installation:
(1) 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.
(2) 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.
(3) Temporarily cap the ends of all conduit run runs immediately after installation to prevent
accumulation of water, dirt, or other contaminants. If necessary, swab out conduits prior to installing the conductors.
(4) Install drain fittings at the lowest point in the conduit run; install seals at the point of entry
to the GC Controller's purged housing to prevent vapor passage and accumulation of moisture.
(5) Use liquid-tight conduit fittings, such as Myers Scru-Tite or similar, for conduit which is
®®
exposed to moisture.
When conduit is installed in hazardous areas (e.g., areas classified as NEC Class I, Division 1, Groups C and D), follow these general precautions for conduit installation:
(6) All conduit runs must have an explosion-proof sealing (potting) fitting located within 18
inches (45.5 centimeters) distance from the conduit entrance to explosion-proof housings.

- Use small sizes to minimize time lag and prevent back diffusion.
- Install a minimum of one filter to remove solid particles. Most applications require
fine-element filters upstream of the Analyzer.
- Do use ceramic or porous metallic type filters. Do not use cork or felt filters.
Pressure Regulators and Flow Controllers in Sample Line: Do not use types containing cork or
felt filters, or absorbent diaphragms.
Pipe Threads, Dressing: Do use Teflon tape. Do not use pipe thread compounds (dope).
Valving:
- Install a block valve downstream of sample takeoff point for maintenance and
shutdown.
- Block valve should be gate valve or cock valve type, of proper material and packing,
and rated for process line pressure.

A preferred method for operating a Model 1000 GC System is from a connected personal computer (PC). The PC must be...
(a) running MON2000 software, and (b) connected to the GC System by a serial link.
This section of the manual addresses the various possibilities for wiring a serial connection between a PC and the GC System.
3.4.3.1 Before Connecting
Before connecting a PC to the GC Controller, determine the following:
(1) What serial ports are available at the PC? When you select one, consider these points:
(a) FACT: Standard PC serial ports are type RS-232.
(b) 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).
(c) PC serial ports can be designated as "COM1" through "COM8," and they can be used
by other peripheral equipment attached to the PC, such as printers, mice, or modems, etc.
3-38
INSTALLATION AND SETUP
MODEL 1000 SEP 2005
You will need to connect the GC Controller to one of the PC's available, or unused serial ports.
To determine which PC serial ports are already being used by other equipment and which port can be used for connecting to the GC Controller, note existing serial connections, refer to your PC user's manual, and use diagnostic software (such as Norton Utilities™).
(2) What serial ports are available at the GC Controller? When you select one, consider these
points:
(a) The GC Controller's COM1 serial channel is usually reserved for connecting a PC,
especially for service or troubleshooting purposes, since the GC Controller's easy-access front panel serial port is connected to serial channel COM1 (see Figure 3-7).
Figure 3-7. The Front Panel Serial Port is Connected to GC Controller's Serial Channel
COM1
INSTALLATION AND SETUP
3-39
SEP 2005 MODEL 1000
(b) COM8 is used for the display/keypad when unit has COM5-8 option (COM4A
Board). However, when the unit has a display/keypad but does not have the COM8 option, COM4 must be RS-232, and is used for the display/keypad. Therefore, there is no COM4 output on the field terminal board.
(c) The optional Modem piggy-backs on to the CPU 104 BUS (See Internal Modem for
the Gas Chromatograph, drawing BE-20767).
(d) Any one of the Controller's eight serial channels could also be reserved for
connecting to a Data Collection Systems (DCS) or multi-drop serial data highway system (and thus, would be unavailable for a serial PC connection).
(3) Is the connection to be made in a...
- Nonhazardous environment?
- Short distance between the PC and Controller?
- With temporary or permanent cable connection?
(a) See Section 3.4.3.2, "PC-to-GC, Front Panel Quick and Easy RS-232."
(4) Is the connection to be made in a...
- Hazardous or nonhazardous environment?
- Short distance between the PC and Controller?
- Permanent cable connection?
(a) See Section 3.4.3.3, "PC-to-GC, Permanent Cable Connection for Short Distance RS-
232."
(5) Is the connection to be made with a...
- Long distance between the PC and Controller?
- Permanent cable connection?

INSTALLATION AND SETUP
MODEL 1000 SEP 2005
3.4.3.2 PC-to-GC, Front Panel Quick and Easy RS-232
The easiest way to connect a PC to the GC Controller is with an 'off-the-shelf', straight-through serial cable connected to the GC Controller's front panel DB-9 serial port jack.
To connect a PC to the GC Controller's front panel DB-9 serial port jack, proceed as follows:
SERIOUS PERSONAL INJURY OR DEATH POSSIBLE
Do not operate a PC in a hazardous environment. Do not make or break front panel wiring connections in a hazardous environment. In a hazardous environment, ensure that field connections to the Analyzer or GC Controller (including serial port) are made through explosion-proof conduit or flameproof glands.
Failure to observe all safety precautions could result in serious injury or death.
(1) Obtain a "straight-through" serial cable:
(a) 50 feet long or less,
(b) DB-9 or DB-25 female plug at one end (for PC connection), and
(c) DB-9 male plug at the other end (for GC connection).
(d) You can buy this type of cable, with plug-ends already installed, from most computer
supply retailers, so there should be no need to custom-wire a serial cable for this type of connection. (If, however, it is necessary to custom-wire a cable because of circumstances, see guidelines provided in Appendix A, this manual.)
(2) Connect the serial cable's plugs to the appropriate serial port jacks at the PC and GC (front
panel). Then use the software MON2000 to "Connect" and operate the GC as needed.
INSTALLATION AND SETUP
3-41
SEP 2005 MODEL 1000
3.4.3.3 PC-to-GC, Permanent Cable Connection for Short Distance RS-232
Another way to connect a PC to the GC Controller is with straight-through serial cable connected to one of the GC Controller's internal serial ports located on the Controller's Terminal Board for Field Wiring (TB).
If the length of cable can be 50 feet or less, connect the serial cable to one of the GC Controller's serial ports configured for RS-232. (Recall that output from a standard PC serial port follows RS­232 serial definition.) Cable that is longer than 50 feet, when used for RS-232 serial transmission, can result in spurious loss or corruption of data.
To connect a PC to one of the GC Controller's internal serial port jacks, proceed as follows:
(1) Access the GC Controller's Terminal Board for Field Wiring (TB).
(a) If necessary, see instructions provided in Section 3.4.1, step (1).
(2) Choose an available serial port on the TB that is configured for RS-232 serial protocol.
Unless specified otherwise by customer order, all serial channels on all versions of the GC Controller are configured by default from the factory for RS-232. For the Rack mount, retrofit, and purged versions of the GC Controller, and serial channel, COM4 is used for the keypad and display without the COM4A Board. With the COM4A Board installed, COM8 is used for the keypad and display. For further details, see Section 3.4.4, this manual, and drawing DE-20782, GC Controller drawings addendum.
(a) The easiest option is to use a "straight-through" serial cable, like the one described
for the GC Controller front-panel connection (see Section 3.4.3.2), and connect it to either one of the DB-9 female jacks on the TB.

(b) Another option is to use a Direct Serial Connect Cable (P/N 3-2350-068), or fabricate
one like it.
- Connect the DB-9 female plug end to the DB-9 male serial port on the PC.
- Connect the cable's exposed leads to the GC serial port on the TB.
- When the DB-9 female plug of the cable is connected to a standard PC, its six leads will be configured for RS-232 as shown in Table 3-4.

3.4.3.4 PC-to-GC, Long Distance with RS-422 or RS-485
RS-422 and RS-485 serial protocols are recommended for longer distance serial connections between the PC and GC System (i.e., distances greater than the 50 feet).
To connect a PC to one of the GC Controller's internal serial port jacks that accept RS-422 or RS-485 serial protocol, proceed as follows:
(1) Obtain the following equipment:
(a) An asynchronous line driver / interface device with RS-232 input, and RS-422 or RS-
485 output. (See Appendix A, this manual, for example brand and model.)
(b) Shielded, computer-grade, twisted pair cable (to connect the asynchronous line driver
device to the GC).
(c) A straight-through serial cable (to connect the PC to the line driver).
(2) Connect the straight-through serial cable from the PC's serial port to the RS-232 serial port
of the line driver device. Then connect the twisted pair cable to the RS-422/RS-485 serial port of the line driver.
(3) Configure the line driver for data communications equipment (DCE) operation. (See
Appendix A, this manual, for an example configuration of a "Black Box" brand, model LD485A-MP "RS-232/RS-485 Multipoint Line Driver.")
(4) Access the GC Controller's Terminal Board for Field Wiring (TB).
(a) If necessary, see instructions provided in Section 3.4.1, step (1).

(5) Choose an available serial port on the TB that is configured for RS-422 or RS-485 serial
protocol, and connect the twisted pair cable from the line driver. (See Appendix A, this manual, for example connection.) (Also see Section 3.4.4, this manual for list of ports and terminals assigned to serial communications.)
When the unit has the COM4A Board installed, COM8 is used for the display/keyboard. However, if the unit does not have the COM4A Board installed, the display/keyboard uses COM4 and it must be RS-232. Therefore, there is no COM4 output on the Field Termination Board.

The GC Controller has four serial communications channels: COM1, COM2, COM3, and COM4. Through jumper settings, they can be configured for the following serial signal definitions: RS-232, RS-422, or RS-485.
The serial signal definitions and the ports that support them are as follows:

The serial ports and terminals listed above are located on the GC Controller’s Terminal Board for Field Wiring (TB).
Serial ports configured for RS-232 are most commonly used for direct serial communication between the Controller and a PC or modem.
