(2) Precautions for Explosionpr oof section (The analyzer with optional code "FM/CSA T ype Y purging" does not have the e xplosionproof section.)

When handling the screws on the cover of the Protection system, note the following to avoid damaging the screws since they cannot be repaired.

(1) The enclosure is pressurized. Before removing the cover, reduce the internal pres-

sure by loosening the sealing plug for wiring on the enclosure or relevant means.

viii

(2) When removing the cover, prevent any dirt or foreign matter from contaminating the

screw part.

(3) When installing the cover, tighten the screws by hand ; never use tools. (4) Since the screws are coated with MOL YKOTE, do not lubricate them.

(3) Precautions when using hydrogen gas

When using hydrogen gas as the carrier gas, the FID or FPD combustion gas, to ensure safety , install the analyzer in a location equipped with a ventilator or where there is sufficient ventilation. Make sure there are no gas leaks from the pipe joints and inspect for leaks.

(4) Installation site and environment

The analyzer specifications allow it to be used in hazardous areas as defined by Zone1 IIB + H

, T2, T3, T4 (JIS / CENELEC) or DIV1, GPS B, C & D, T1, T2, T3, T4 (FM / CSA).

2T1

However, never install the analyzer in an area where the density of explosive gas persists for a long time.

(5) Wiring works

Model GC1000D / GC1000S, analyzer obtains explosion proof authorization by the complete set including metal fittings of the attachment.

When performing wiring, always use the attached sealing fittings and flameproof packing adapter.

IM 11B03A03-01E 3rd Edition : Aug. 23. 2006-00

(6) Maintenance and inspection

During usual maintenance and inspection, it is not necessary to check the explosionprotected section.

Before opening the door of the explosion-protected section for maintenance and inspection, be sure to turn off the power . After completing maintenance and checks, close the door completely then turn on the power after checking that the specified explosion protection performance is guaranteed. The parts to be checked are described in the Maintenance and Inspection Manual (IM 1 1B03A03 - 04E).

If any of the following damage occurs, contact a Yokogawa sales representative or the Y okogawa sales division

(1) If the screws securing the Protection System (explosionproof construction) are dam-

aged

(2) If the exterior or light transmission section of the enclosures is damaged (3) If packings are cracked or conspicuously deformed

(7) Override function (The analyzer with optional code "FM/CSA T ype Y purg ing" does not have this function.)

WARNING

• When the override function is used, Analyzer becomes an ignition source and the high temperature and the high voltage part will be exposed.

• Please confirm that in the ambient atmosphere, the concentration of explosive gases is less than the allowable limit, by using a gas detector.

To return to the normal operation, turn off “the override switch” and then close the door as it was before turning on power.

In this analyzer, if the pressure of the pressurized / type X purged enclosure system (oven, electronic section) drops while the power is on, the pressurized explosion protection section is activated to stop power supply . Therefore, in case of opening the door of the oven or of the electronic section inadvertently , for maintenance, while the power is on, the protection system is activated to cut off the power .

The “override function” intensively releases this function of protection system.

The override switch is installed in section.

(8) Replacing parts

Always use parts specified by Yokogawa when replacing parts, for replacement, refer to the Maintenance and Inspection Manual (IM 1 1B03A03 - 04E).

1. Principle of Gas Chromatograph

A gas chromatograph is an analyzer which first sends a fixed volume of the sampled multicomponent gas mixture to a column, separates it in the column, then measures the concentrations of the components with a detector. The process gas chromatograph analyzes intermittently , allowing periodic analysis in a specified sequence, thus automatic sampling is possible.

This chapter explains the measurement principle of the GC1000 Process Gas Chromatographs.

1.1 Sampling Mechanism

The process gas chromatograph consists of a sampling mechanism, a column and a detector.

Sampling is carried out by switching a sampling valve. When separating components or detecting concentrations, the sampling valve is set to allow the gas (liquid) to be measured to flow through the sample column. When sampling, the sampling valve leads the gas (liquid) to be measured to a column on a carrier gas. (See Figure1.1)

There are two important points regarding sampling: a regular volume is sampled since repeated sampling is required; and samples are taken quickly and securely . The volume is fixed by measuring a specific gas (liquid) of controlled temperature and pressure using a sample measurement tube. Samples are taken quickly and securely by ensuring that the gas to be measured always flows without interrupt.

1.2 Component Separation Using Column

Three types of columns are available for the GC1000 Process Gas Chromatographs: the packed column, the mega-bore column and the capillary column.

The packed column consists of a stainless pipe, 2 mm in diameter and 0.2 to 2.0 m in length and filled with a bulking agent called a stationary phase.

The mega-bore and capillary columns, of approximate diameter 0.5 mm and 0.3 mm respectively , are coated inside a certain phase called a stationary phase.

The components in the multi-component gas mixture sample with carrier gas, which called mobil phase move through the column, repeatedly absorbing the stationary phase and dissolving from the stationary phase at a certain cyclic rate conforming to a fixed partition coefficient * that is unique to each component.

Since the transfer rates differ depending on the partition coefficient, a multi-component gas mixture gradually separates into discrete components and is separated in the order of the transfer rates.

* Partition coefficient : The concentration ratio of the components, calculated by dividing the component concentration which

is in equilibrium in the stationary phase by the concentration which is in equilibrium in the mobile phase.

Figure 1.2 shows a diagram of how the multi-component gas mixture is led to a column and separated into its discrete components over time.

1.3 Detector

The components separated in the column are led to the detector where the concentration of each component is measured.

The GC1000 Process Gas Chromatographs can be fitted with thermal conductivity detectors (TCD), flame ionization detectors (FID) or flame photometric detectors (FPD). The thermal conductivity detector can measure almost all non-corrosive components but sensitivity is relatively low. On the other hand, the hydrogen flame ionization detector can measure hydrocarbon and the flame photometric detector can measure sulfur compounds, respectively with high sensitivity .

(1)Thermal Conductivity Detector (TCD)

The TCD utilizes the difference in the thermal conductivity between the measured gas and the carrier gas and detects the unbalanced voltage produced in a bridge circuit as a measure of concentration.

Figure 1.3 shows the fundamental principle of the TCD. As shown, there are two streams, each having two filaments. One stream passes the carrier gas only and the other, connected to the column outlet, allows the measured gas to pass during analysis. The filaments in the two streams form a bridge circuit such that the filament in one stream is adjacent to the filament in the other stream. The unbalanced voltage in the bridge is proportional to the concentration of the measured gas (liquid) component.

1-3

The TCD is frequently used to measure the component concentration of the measured gas (liquid).

(2)Flame Ionization Detector (FID)

The FID utilizes the phenomenon that carbon molecules in the measured component (hydrocarbon) are ionized in a hot hydrogen flame. That is, it detects the ionization current which flows between electrodes to which a high voltage is applied. The ionization current is proportional to the concentration of the measured component.

The FID is used to measure the component concentration of gases containing low concentrations of hydrocarbons.

(3)Flame Photometric Detector (FPD)

Figure 1.5 shows the structure of the FPD. As the sample gas containing a sulfur component is led into the excess hydrogen flame, the component containing the sulfur atoms is excited. The FPD detects the luminous intensity of the light emitted when this excited component return to its base state using multiplier phototube and converts it to a voltage. This voltage represents the concentration of the sulfur component in the measured gas.

The FPD can measure on the sulfur component with a high sensitivity of 1 ppm.

3.2 Components and Their Functions

3.2.1. Protection System

The protection system has a explosion-proof construction and is equipped with a built-in protection circuit. The power relay , pressure switch, timer , relays, override switch, etc. are internal to the instrument. The override function is particularly important for maintenance, since it allows the power to be turned on even if there is an internal pressure loss. The system monitors the internal pressures of the electronic section, isothermal oven and the programmed-temperature oven (GC1000D / GC1000T / GC1000W), and if any of them indicates an internal pressure lower than 392 Pa, it shuts down the power supply to those components. After a power shut-down, when the internal pressure is restored, the system automatically purges over the 12 minutes, then turns on the power again. Analyzers of nonexplosion-proof type and with FM/CSA T ype Y purging do not have this protection system.

3.2.2 Electronic Section

The electronic section has a pressurized protection/Type X purged structure and is designed for control of a detector, an isothermal oven, various valves and others, for processing and computation, and for output of the results. The LCD and operation keys on the front of the electronic section allow manual operation of the GC1000 Mark II.

3-2

3.2.3 Pressure and Flow Control Section

The pressure and flow control sections control and indicate the pressures of sample gases, standard gases, carrier gases, FID or FPD hydrogen (or nitrogen) for combustion, or FID or FPD air for combustion. Regulator values or EPC is installed. It also contains pressurereducing valves for controlling purge gases, the air for actuating valves or the vortex tube, an air-actuated valve for balancing atmospheric pressure, a vortex tube and a hydrogen restriction system.

3.2.4 Isothermal Oven

The isothermal oven has an pressurized protection / T ype X purged structure. The temperature is set at a fixed level from 55 to 225°C (setting by 1°C unit). The isothermal oven contains valves such as the sample valve which is air-activated, the back flush valve, the column for separating a multi-component gas mixture into its individual components and leading the components to the detector in sequence, the detector for detecting the components, and the restrictor for controlling the gas flow rate, etc.

There are three types of detector, the thermal conductivity detector (TCD), the flame ionization detector (FID) and the flame photometric detector (FPD); either one or two of these detectors can be used simultaneously (however, the FPD can only be installed in the combustion chamber).

The component signals picked up by the detector are led to the electronic section for signal processing.

IM 11B03A03-01E 3rd Edition : Aug. 23. 2006-00

3.2.5 Programmed-temperature Oven

The programmed-temperature oven has an internal pressure protection / T ype X purged structure. It contains a column that separates multi-component mixture samples into individual components and leads them to the detector in sequence. The temperature can be set to a fixed setting or it can be programmed. The allowable temperature range is 60 to 320°C without a cooling system, or 5 to 320°C with a cooling system, and the temperature can be set to rise from between 0.1 to 30°C/min (setting by 0.1°C unit). Up to three temperature-rise patterns can be programmed.

3.2.6 Analyzer Base Sampling Section

The analyzer base sampling section is equipped with sample and standard gas streams, and controls the sample pressure and flow rate. It also selectively sends the sample to be analyzed in a stream, and can switch the standard gas to the isothermal or the programmed-temperature oven by a valve depending on the signal sent from the electronic section.

If the analyzer does not contain the analyzer base sampling section, then samples can be processed externally by supplying air to a separate sampling section.

4.1 Status and Operation Mode

The GC1000 Mark II has the following statuses:

• Process: Normal measurement, calibration and validation

• Manual: Manual operation

• Lab: Measurement with automatic peak detection, like a laboratory GC

The GC1000 Mark II has the following operation modes:

• Stop: Mode in which the measurement stops

• Run: Mode in which the measurement is running

• Pause: Mode in which the measurement pauses

Figure 4.1 shows the transitions of statuses and operation modes.

When the LCD panel on the GC1000 Mark II or the LCD emulator on a personal computer (PC) connected with the GC1000 Mark II is used, by changing the operation panel to the manual operation panel or lab operation panel, the status will change from Process to Manual or Lab. Likewise, by changing the manual operation panel or lab operation panel to the operation panel, the status will change from Manual or Lab to Process.

When the GCMT on a PC connected with the GC1000 Mark II is used, the status can be changed through command button operation or menu-driven operation.

The following pages describe each status and operation in detail.

4.1.1 Process

In the Process status normal process measurements, calibration, and validation are performed. When power is applied, the status enters Process.

The Process status contains the following measurement statuses.

• Stream Sequence: Continuously measures streams in order specified in Stream Sequence

• Stream (continuous): Continuously measures the specified stream

• Stream (1 cycle): Measures the specified stream once

• Calibration/V alidation: Performs calibration or validation of the specified number

Figure 4.2 shows the transitions of measurement statuses.

(Same as the status)

Note: When Calibration/V alidation has been specified from Stream Sequence, the measurement status returns to Stream

Sequence after the completion of calibration/validation. When Calibration/Validation has been specified from Stream (continuous), the measurement status returns to Stream (continuous) after the completion of calibration/validation.

The following explain each measurement status in detail.

(1) Stream Sequence

In the Stream Sequence status, the analyzer continuously measures multiple streams in order. When power is applied, the measurement status enters Stream Sequence. Four kinds of stream sequences can be used with the GC1000 Mark II. For each steam sequence 31 streams can be set in order. If number "0" is set as a stream number , the measurement skips the order and goes to the stream specified in the following number. Note that number "0" cannot be set as the first stream number, which needs any number between 1 and 31 to be specified.

(2) Stream (continuous)

In the Stream (continuous) status, the analyzer continuously measures the specified stream. With the GC1000 Mark II, 31 streams can be specified. In the Stream (continuous) measurement status, the analyzer measures the stream specified from among the 31 streams.

(3) Stream (1 cycle)

In the Stream (1 cycle) status, the GC1000 Mark II measures the specified stream once. Like Stream (continuous), the analyzer measures the stream specified from among the 31 streams.

(4) Calibration/Validation

In the Calibration/V alidation status, calibration or validation is performed using a standard sample. V alidation is to verify, using a standard sample, whether the measurement of the GC1000 Mark II is normal. This function can be used in combination with calibration: calibration is conducted when the increased error between a measurement result and a standard sample is seen during the regular validation.

IM 11B03A03-01E 3rd Edition : Aug. 23. 2006-00

Three ways of calibration and three ways of validation can be used with the GC1000 Mark II.

There are three methods for Calibration/V alidation: automatic, semiautomatic and manual. The following explain the actions of three methods.

•Automatic

Calibration or validation is conducted automatically at the specified time. This function is only available when automatic valves are used for streams for calibration or validation.

When Calibration/V alidation is set to automatic, the analyzer starts calibration or validation at the specified starting time and subsequently conducts calibration or validation every time after the specified interval time elapses. When the operation mode is in Stop or Pause at the time of automatic calibration or validation, the calibration or validation for the time is cancelled.

• Semiautomatic When the calibration number or validation number is specified, the valves for streams

for calibration or validation automatically open and the analyzer performs calibration or validation. This function is only available when automatic valves are used for the stream.

• Manual

4-3

When the calibration number or validation number is specified, the valves for all streams are closed so that the analyzer is ready to allow a standard sample to flow. The standard sample is supplied manually for displacement, making the analyzer ready to accept a command. After the displacement is conducted adequately, the analyzer performs calibration or validation by the start command.

Each measurement status has the following operation modes, with the exception of the Stream (1 cycle) and Calibration/V alidation statuses which do not have Stop and Pause.

• Stop: Mode in which the measurement stops

• Run: Mode in which the measurement is running

• Pause: Mode in which the Run mode pauses

For the transitions of the operation modes, refer to Figure 4.1. To transfer from the Run mode to the Stop mode, two commands are used: stop command

and forced stop command, which are explained below.

• Stop command

The measurement stops after an ongoing measurement has been completed.

IM 11B03A03-01E 3rd Edition : Aug. 23. 2006-00

The following explain each operation mode in detail.

(1) Stop

In the Stop mode the measurement stops. When power is applied, the operation mode enters Stop. Settings should be changed in this Stop mode.

CAUTION

If settings are changed in an operation mode other than the Stop mode, the analyzer may not accept the change and run under the previous setting.

When the operation mode is transferred to the Stop mode from others, the on-off statuses of various valves and stream valves remains unchanged.

(2) Run

In the Run mode, the measurement runs. If the Auto Start Set is set to Enabled, the GC1000 Mark II automatically enters the Run mode after the time set for the "Auto start time" elapses after power is applied. When the operation mode is transferred from the Stop mode to the Run mode, the measurement starts after the Warming up time for displacement in the sample stream elapses. For the Warming up time, see Section 4.3, “Method”. If a level 1 alarm occurs during the Run mode, the mode changes to the Stop mode after an ongoing measurement of the stream has been completed.

4-4

(3) Pause

In the Pause mode, the measurement pauses at the specified Pause Time. For the Pause Time, see Section 4.3, “Method.”

When the operation mode is transferred from the Pause mode to the Run mode, the measurement resumes at the Pause Time.

When the operation mode is transferred from the Stop mode to the Pause mode, the on-off statuses of various valves including stream valves become those at the Pause Time of the stream to be measured next.

IM 11B03A03-01E 3rd Edition : Aug. 23. 2006-00

4.1.2 Manual

In the Manual status, various operations and measurements can be performed manually . The operations available in the Manual mode are:

• On/off of various valves

• On/off of stream valves

• On/off of several heaters

• On/off of several types of detector (only On for FID and FPD)

When the status is transferred from Process to Manual, all the various valves and stream valves turn Off.

The Manual mode contains the following operation modes.

• Stop: Mode in which measurement stops

• Run: Mode in which measurement runs

For the transitions of the operation modes, refer to Figure 4.1. The following explain each operation mode in detail.

(1) Stop

In the Stop mode the manual measurement stops.

4-5

4.1.3 L a b

(2) Run

In the Run mode the manual measurement runs. During the Run mode, the GC1000 Mark II detects peaks automatically until the mode turns to Stop. When the mode turns to Stop, the concentration in area percentage is calculated from the area of peaks detected. The calculated concentration values are displayed on the Laboratory Analysis Results display panel. For five seconds after the operation mode turns from Run to Stop, the GC1000 Mark II does not accept the run command in order to process analysis calculations and others.

In the Lab status the lab measurement runs. The GC1000 Mark II performs continuous measurements for times specified in the lab settings.

In the Run mode in Process, peaks are detected according to the on/off of the set gate, while in Lab, peaks are detected automatically like a laboratory GC. This mode can be used for determining gate timing when a column system is changed.

The Lab mode contains the following operation modes.

• Stop: Mode in which measurement stops

• Run: Mode in which measurement runs

For the transitions of the operation modes, refer to Figure 4.1. The following explain each operation mode in detail.

(1) Stop

In the Stop mode the lab measurement stops.

(2) Run

In the Run mode the lab measurement runs. In the Run mode, GC1000 Mark II performs measurements according to the lab settings. If a level 1 alarm occurs during the Run mode, the mode changes to the Stop mode after an ongoing lab measurement has been completed.

IM 11B03A03-01E 3rd Edition : Aug. 23. 2006-00

4.2 Stream

In the GC1000 Mark II, 31 streams can be used. Parameters needed to be specified for streams are:

• Stream valve number

Any one stream valve number from among the numbers of 1 to 31 should be specified for a stream.

If the stream valves are automatic, the stream valve of the specified valve turns on/off. If the stream valves are manual, this setting does not have any effect on the operation.

The same stream valve number can be specified for different streams. When multiple measurements are performed in one stream, the same stream valve number should be specified.

A standard sample stream should be specified as one of the streams.

• Method number

Any number from 1 to 4 should be specified for a method number.

There are three types for the stream:

• Measurement stream

4-6

Used for measuring process samples.

• Validation stream

Comparing measured results before and after calibration, or checking if the GC1000 Mark II is operating properly can be performed using a standard sample. The validation stream is used for standard sample measurement in such case.

• Calibration stream

Used for measuring a standard sample at calibration. The calibration stream may be used in combination with the validation stream.

IM 11B03A03-01E 3rd Edition : Aug. 23. 2006-00

4.3 Method

Activation timing for various valves and parameters with regard to the temperature of the isothermal/programmed-temperature ovens should be specified for Method. Four Methods can be used with the GC1000 Mark II. Parameters needed to be specified are described below. For setting procedures, refer to the LCD Panel Operation Manual, IM 11B03A03-05 E.

• Analysis cycle

Time from start (0 second) to stop of analysis

• Warming up time Time required for displacement in sample streams. An appropriate displacement time

should be determined considering the diameter and length of the sample stream tubing, sample flow rate and delay time.

A positive value should be specified for the W arming up time. But displacement in sample streams is implemented before the start of analysis (0 second) so that the Warming up time actually acts as a negative value.

• Peak detection stop time

Time to stop peak detection compulsorily, which is usually specified to around five seconds earlier than the pause time. The time must be the analysis cycle time minus one second, or less.

4-7

In case of the GC1000D/GC1000T/GC1000W, the heater should be turned of f at the time of peak detection stop time.

• Pause time

Time when the GC1000 Mark II can be stopped without adversely affecting the column system. Usually the pause time should be set after peaks of all components have been eluted (after the peak detection stop time) for the analysis cycle time minus 3 seconds, or less.

• DO on time/DO off time

These can be used for notifying a supervisory computer or system of analysis end timing and other information by using contacts. They can also be used as a reading signal when analog outputs are employed.

• Stream valve on time/stream valve off time

Time to turn on/off stream valves. As stream valves usually turns on from the Warming up time, the stream valve on time should be set as a negative value. The values to be set should be the Warming up time minus one second, or more, and the analysis cycle time minus two seconds, or less.

• V1 to V8 on/off time

Time to turn on/off valve 1 to valve 8 - sample valves, back flush valves, column switching valves, and atmosphere balance valves. On/off can be set for three times each. The time to be set should be the Warming up time minus one second, or more, and the Analysis Cycle Time minus two seconds, or less.

• Initial control temperature

Displayed on the GC1000D/GC1000T/GC1000W that uses a temperature program. The temperature of the programmed-temperature oven at the start of analysis should be specified.

• Initial temperature time

Displayed on the GC1000D/GC1000T/GC1000W that uses a temperature program. The time for holding the initial control temperature should be specified.

4.5 Computation and Processing

The following are processed using chromatograms obtained as detection signals. For the setting procedure, see the LCD Panel Operation Manual, IM 1 1B03A03-05E.

• Peak processing

• Deviation processing

• Additional processing

• Signal processing

Each processing is outlined below. For details, see the Technical Guide, IM 11B03A03-03E.

4.5.1 Peak Processing

This processing detects peaks from a detector signal and determines the concentrations of components based on the area or height of each peak. The retention times, peak half-width and so on are also determined from the detected peaks.

4.5.2 Deviation processing

This processing determines the value obtained by subtracting the sum of the concentrations of components computed by peak processing from the total sum of set concentrations.

4-20

4.5.3 Additional processing

There are the following three types of processing in the additional processing:

• Linear computation processing This processing determines the total sum of the concentrations of each component

computed in the peak processing multiplied by individual coefficients.

• Ratio computation processing This processing determines the ratio of concentrations of two components obtained

by the peak processing.

• Separation capability processing This processing determines the separation capability using retention time and peak

half-widths of two adjacent components determined by the peak processing.

IM 11B03A03-01E

3rd Edition : Aug. 23. 2006-00

4.5.4 Signal Processing

There are three types of processing in the signal processing:

• Base level processing The detector signal at a time set for base level processing within the analysis cycle

avoiding component signals is used as the base level value. If the base level processing is not set, the detector signal immediately after the start of analysis is employed as the base level value.

• Signal level processing The differences between the detector signals at each time set for signal level process-

ing within the analysis cycle and the base level value, are used as the signal level values. If more than one base level processing is set, the base level value immediately before a base level processing is used for signal level processing.

• Noise level processing Among the preceding 20 data for detector signals at a time set for noise level process-

ing within the analysis cycle, the maximum and minimum values are used as noise level values.

4-21

IM 11B03A03-01E

3rd Edition : Aug. 23. 2006-00

4.6 Alarm Processing

There are four alarm levels. For details of alarms, see the Alarm Message Manual, IM 1 1B03A03-06E.

• Level 1 Alarms for system or hardware failures. When an alarm is generated, the alarm

condition is maintained until it is reset. If a level-1 alarm is generated in the Run or Lab mode, the operation mode changes to

Stop at the end of the measurement being executed.

• Level 2 Alarms for measuring conditions failure. When an alarm is generated, the alarm condition is maintained until it is reset.

• Component Alarms when measurement results such as concentrations and retention times be-

come out of each specified range. If an alarm is generated, the alarm condition is maintained until it is reset.

• Level 3

4-22

Alarms for minor failures or information other than level-1 and level-2 alarms. The alarm condition is not maintained.

5. Actions of External Input and Output Signals

5.1 Analog Hold Output

Up to 36 outputs are available as option. Actions of analog hold output are different between when the actual stream is specified and

when "99" is specified for the stream number in setting analog hold output. Actions of contact output are different whether a contact output is used or not as a stream identification signal. The following explains actions of analog output as well as contact output. If "99" is specified for the stream number, contact output must be used as a stream identification signal. For actions of contact output other than stream identification signals, refer to Section 5.2, “Contact Output.”

(3) Holding Register (Set Data)

(1) Time setting value

This is a set of four registers used by the DCS to set the device clock. When the time setting request coil (address 00003 for GC1000 Mark II and GCIU, 00001 for the analyzer server) is activated, these entries are used for the year, month/day, hour and minute/second. Since all devices on the highway synchronize to the analyzer server clock on a regular basis, the analyzer server clock should be regularly set.

(2) Range setting command

This address allows the range of the component indicated by the specified stream number and peak number to be changed on the GC1000 Mark II.

(3) Analysis value

These addresses display the same data as the analysis value in the input resister, however values cannot be written to theses addresses. Only these addresses support real number (floating point) form.

(4) Input Register (Measured Data)

(1) Stream number

The currently active stream number on the GC1000 Mark II is displayed. In Stop or Manual mode, the stream number is 0. In Lab mode, the stream number is 32.

(2) Starting peak number

The starting peak number assigned to each stream on the GC1000 Mark II is displayed. The maximum number of analysis values, including peaks of all streams, is

255. The number is 0 if no peak is assigned.

(3) Peak number

Peak number assigned to each stream on the GC1000 Mark II is displayed. See the Figure 5.5 below.

Example: the peak number of Stream 2, Peak 3 is 7.

This register contains the latest sampling time for each stream on the GC1000 Mark II. Hour and minutes are stored.

Example : 15:23

Hour Minute

0F17 (hexadecimal)

F0520.EPS

(5) Analysis value

This register contains each analysis value. The value is represented by a fraction to the full scale or by a real number (floating point format). The full scale is set in advance for each analysis value and the scaling factor is user selectable as either 9999 or 65535. The real number format conforms to the IEEE standard and requires two registers per peak.

The fraction format is calculated as follows: (Analysis value x Scaling factor)/Full scale value For example, if the analysis result is 5 ppm and the range is 0-20 ppm, the value read

using a scaling factor of 9999 is

x 9999 = 2499 (09C3)

F0521.EPS

For the real number format, units such as % and ppm are considered. For example, the real number value converted from 1.5 is directly transmitted as 1.5%. The GC1000 Mark II updates analysis values at the end of each cycle. The GCIU updates the average values according to the userset scan interval.

(6) Retention time

This register contains the retention time for each measured stream of the GC1000 Mark II. The unit is in seconds.

IM 11B03A03-01E

3rd Edition : Aug. 23. 2006-00

(7) Calibration factor

This register contains the calibration factor for each calibrated stream of the GC1000 Mark II. Since the factors are in the range of 0.000 to 9.999, each value is multiplied by 1000 and displayed as integers, i.e., 0000 to 9999.
