SECTION 1. INTRODUCTION EQUIPMENT DESCRIPTION The Process Gas Chromatograph PGC2000 separates and measures the individual components of gas or liquid samples. It automatically samples and analyzes process streams, using the analyzer's Gas Chromatograph Controller (GCC) to control analytical functions. The analyzer (see Figure 1-1) may be mounted on a wall, a rack, or a floor stand.
This manual refers to these data sheets and drawings as the “Data Package.” PGC2000 WITH FLAME PHOTOMETRIC DETECTOR When the analyzer has a flame photometric detector (FPD), a panel attached to the left side of the analyzer contains the detector, the detector amplifier, and the high-voltage transformer that provides the spark to ignite the FPD (see Figure 1-2).
SYSTEM VARIATIONS This manual supports the PGC2000 basic analyzer. An appendix to the main manual presents additional instructions for special applications such as PGC2002 (simulated distillation), PGC2003 (PNA), PGC2005 (temperature programmed GC), PGC2007 (fuel sulfur), PGC2008 (olefins), and PGC2030 (Sparging Sample Conditioning System).
Power WARNING The Neutral and Ground (Earth) connections to the PGC2000 must be at earth (0 Volts) potential. Failure to maintain earth (0 volts) potential at these connection points constitutes a serious safety hazard. Voltage and Frequency: 100 VAC (+15, -6 VAC), 50/60 Hz ± 10% 120 VAC ±...

Purge Air Alarm The analyzer contains circuits that detect the loss of purge air to the analyzer and generate alarm signals to the operator. The customer has the responsibility to connect the purge alarm to a visual or audible annunciator located in a constantly monitored area, as required by NFPA 496 (1993). Liquid Sample Valve The Liquid Sample Valve (LSV) utilizes two different connection methods for the sample lines.
New analyzers have the sample lines connected to a mounting plate attached to the LSV's mounting flange, as shown in Figure 2-2. Customer Connections Figure 2-2. LSV CONNECTION METHODS, NEW ANALYZERS You must take extreme care to avoid having the sample lines exert force on the sample connections of the Liquid Sample Valve.
1. Do not remove the tube caps, provided at the analyzer tubing ports to prevent deterioration of the columns, until immediately before making each connection. 2. Use an anticorrosion material for the lines and fittings. 3. To ensure using proper size tubing and pipe, refer to the Outline and Mounting Dimensions Diagram contained in the Data Package.
The manifold vent must be plumbed from the analyzer to a safe area at 0 psia or atmospheric vent. To do this, connect appropriate tubing to the manifold vent (see Figure 2-3) and run this tubing to a hazard-free area. MANIFOLD VENT Figure 2-3.

5. Refer to Figure 2-4 (when EPC is installed, the Pressure Control Panel will be blank). The purge air and heater air pressures should be as specified on the label below the corresponding regulator. Purge Air Panel Pressure Control Panel Figure 2-4.
MATCHING COLUMN FLOWS When you are matching column flows, refer to the Data Package for flow rates and valve configurations. Although methods of matching column flows vary with valve configurations, the following procedures apply to most configurations. Verify flows using a flow meter connected to the point being checked (e.g., cell vent).
Checking Total Column Flow To check column flow using a 10-port sample valve and an 8-port selector valve, perform the following steps (other valve configurations use similar procedures): 1. Turn all valves off as described in the previous paragraph. 2. See Figure 2-6. To check total column flow, set Valves One and Two to ON. 3.

SECTION 4. TECHNICAL DESCRIPTION FUNCTIONAL DESCRIPTION Figure 4-1 shows a typical analytical flow system, using the flame ionization detector for illustration. Connections at the right side of the analyzer cabinet provide all gas and air inputs. Sliding plate valves, liquid sample valves, or a combination of both, provide control and measurement of the sample.
The carrier gas has three purposes: to purge the columns and cell prior to introducing a sample, to sweep the sample into the detector cell, and to backflush the backflush column. An externally mounted pressure regulator and gauge regulate the input flow. The sample system, together with the GCC, controls the calibration sample input.
4. If, after six attempts to light the flame, it still is not lit, the ignition sequence terminates and the hydrogen is shut off. ***** Chroma Board ***** Detector: FID Flame: Lit Ignitor: Off H2: None Hardware Zero: 5.10mV ( 4.7%) Software Zero: 3.18mV...
The cell consists of a polarized jet, a collector, and a chamber in which hydrogen fuel and sample are burned in air. A current, whose magnitude is proportional to the concentration of the sample, flows between the jet and the collector. This current goes to the FID Amplifier Assembly. The FID Amplifier Assembly provides ignition control for the FID cell and amplification of the detector cell output signal prior to routing the signal to the control section for signal processing.
Flame Photometric Detector (FPD) Flame photometric detection works on the principle that when sulfur is burned in a hydrogen-rich atmosphere, luminescence (light) characteristic to sulfur is produced. The FPD cell (see Figure 4-5) consists of a teflon burner chamber equipped with a spark ignition system, and a photomultiplier tube which is thermoelectrically temperature controlled.
Simultaneous Dual Detectors Simultaneous dual detectors function in parallel using any two detectors. To accomplish this simultaneous processing requires one Chroma I/O Board in the analyzer for each detector. Chroma I/O Board #1 is in GCC Card Cage slot 2 and Chroma I/O Board #2 is in slot 1. Stream assignments and method tables determine which detector processes each stream and method.
Figure 4-6). While the Background screen provides information on both detectors, other screens will show the data from only one of the two detectors at a time. ********** B A C K G R O U N D ********** ABB Analytical GCC Remote 0.1 803V031-1R (Sim Dual Det) (C) 2001 19-JUN-2002...
To view the data from the second Chroma I/O Board, enter "2" in the highlighted box on the screen and then press the F2 (Select Chroma Bd and View) soft key.

Select the desired mode for Detector 2 and then press the F2 (Exit and Update) soft key to save this setting. ********** Control Parameters **********...
Since there is no dummy stream in Master/Master mode, all Link column entries are "00". In Master/Slave mode, the Link column in the Stream Assignment screen shows which stream the slave is using. Because only the Master detector controls the actual streams used, this slave stream is a "dummy"...
• Vista Basic commands identify the detector by placing the Chroma I/O Board number after the alarm name (e.g., CUR_STRM (1) or INTEGER = RAI (1,0), where the first digit identifies the Chroma I/O Board). Before starting an analysis, the GCC prompts for the Chroma I/O Board to use during the analysis. The selected Chroma I/O Board must be in Master mode or the analysis will not start.
TCD Amplifier PCB The TCD Amplifier PCB, on the left side wall of the GCC, amplifies the thermal conductivity detector output signal and provides it to the Chroma I/O Board for processing. FPD Amplifier and Interface PCBs The FPD Amplifier PCB linearizes and amplifies the flame photometric detector output signal and applies it to the Chroma I/O Board for processing.
Communications PCB (Option) The Communications PCB, in any open slot in the GCC Card Cage, provides a two-channel interface between the GCC and the VistaNET. This PCB is not used when the analyzer has the optional Ethernet PCB. See "VISTANET OPTION" for a detailed explanation of the VistaNET option. VistaNET Interconnect PCB (Option) The VistaNET Interconnect PCB, located on the side of the GCC Card Cage, provides low-speed interface between the GCC and the VistaNET.

RF = CC/A, for peak area analysis of a given component RF = CC/H, for peak height analysis of a given component • Normalized, in which the controller calibrates the analyzer against the external standard, then calculates the sum of all peak areas and determines the percent contribution of each component peak Normalized calibration requires you to provide the component concentration value of each component to be analyzed in a calibration stream.
between the various components is established (at installation), only the K-factor is changed during calibration. Preparing a Method Table This subsection explains how to prepare a method table by constructing a sample method table. Figure 4-12 shows a chromatogram of the analysis to be controlled. This analysis is 90 seconds long and has three components to measure: A, B, and C.
2. On the Commands screen, cursor down to TABLE EDIT and then press the F2 (Methods) soft key. 3. The Method Table #?? screen will appear (see Figure 4-14). Use the number keys on the GCC front panel to enter the number “1” for this method (the method number given in Figure 4-13 data).
5. Cursor to the Calibration Type line. The current choice is underlined. To change the choice, cursor right or left to the desired type (in this case Ext Std) and then cursor to the next line. Moving the cursor up or down sets the new choice. 6.
14. Enter “30” for Component #1’s time and then cursor right to select “Component.” Since this is the first component entered into the table, “Undefined” will appear in the Value column. 15. Cursor right to the Value column. The Component Definition screen will appear (see Figure 4- 17), which will allow you to define this component.
3. In steps 4 through 7, review the Cal Define & Cycle Time screen and make changes as necessary. 4. When the Method Table #01 (or other number you have chosen) appears, locate the specific line you want to change. 5.
4. On the second Print Tables screen, enter the Method Table number and then press the F2 (Print Selected Table) soft key. The Method Table and Component Table will print (see Figure 4-19). METHOD TABLE #01 8:25:29 Fri 30 Sep 1994 Cycle Time = 00140 TIME FUNCTION...
method has forced gating and slope detection on at the same time, the controller uses the one turned on first, ignoring the second one and sending an alarm to tell you that both peak detection methods were on. Forced Gating When a component's elution time is known, forced gating can measure the peak.
higher number causes the system to respond less quickly but is more sensitive. For that reason the default is set at 8, a median value that provides both good response and sensitivity for most applications. Peak width only has meaning when slope detect is running. Slope Detect On tells the method that slope detection will be used for this analysis.
peak which begins on a valley point (see Figure 4-22). Since the tangent skim termination search operates only during a single peak, it is activated by setting Tangent Skim at the proper time in the method table (no On/Off is required). To use tangent skim, choose a time in the method table that occurs at a point before the peak in question and set Tangent Skim.
different peak areas in adjacent analyses (see Figure 4-23). By selecting “Pk End =Vly” you can force the routine to call it a valley each time it occurs, thus removing the indecision and stabilizing the calculations. “Pk End =Base” is used the same way as “Pk End =Vly.” Selecting “Pk End =Vly” or “Pk End=Base”...
“Proj Reverse” is a reverse projection flag that identifies the end of a desired peak or group of peaks. It is set in the baseline after the end of the peak (see “HBR” in Figure 4-25). With reverse projection, “Proj Term” is set before the start of the peak—and before “Proj Reverse” (see “HBT” in Figure 4-25). The system then measures the peak that occurs between HBT and HBR.
Another method for handling badly tailing peaks is “End=Crest+” (see Figure 4-27). This code forces the end of the peak to be the crest time plus the time specified in the code, providing a reproducible end to the peak even if the crest of the peak is moving. To use this command, insert “End = Crest+” into the method together with a specified time after the crest.
NOTE If any of the above conditions exist, an error will occur. Stream Step Stream Step begins the automatic sample purge of the sample stream being analyzed. It must occur after completion of the sample inject for this stream. This is particularly important when the current stream being analyzed requires multiple sample injections.

Short Report This report (see Figure 4-34) gives basic information on the analysis, which you can use to check analyzer operation periodically. It is a one-line report which provides the stream number, injection time, and concentration for each component by number. The Short Report comes in two forms: •...
will reduce the classification to Nonhazardous/General Purpose. Since the Y and Z Purge systems are identical except for nomenclature, the following explanation applies to both. The purge air enters the analyzer system through a pressure regulator, an orifice, and a gauge used to set purge flow, and then into the electronics housing where purge air flow is maintained until a fault condition exists.
The X Purge cycle time depends totally on the application, but it may vary with analyzer configuration and condition. Refer to the analyzer label or Data Package for specific purge specifications. Once X Purge applies power to the analyzer, power continues to the analyzer as long as the electronics housing maintains air purge pressure.
6. With X Purge reset, the air purge timed cycle begins in the electronics housing. When you use Override during start-up, it overrides the X Purge control of power to the analyzer, but the air purge timed cycle continues. Once the electronics housing has pressurized and X Purge completes its timed purge cycle, the analyzer will have power from the X Purge.

Reprocessing takes saved data and sends it back through peak detection in an off-line mode, then produces a report available to VistaNET (but not displayed on the screen).
REMOTE GC OPERATION OPTION The analyzer can operate with other ABB GCC front panels. To implement this option requires the following changes to the analyzer: an optional PCB and several changes in wiring connections and switch settings. This section of the manual explains how to prepare the analyzer for remote operation and how to operate it in this configuration.
The first five switch positions on SW1 (labeled 0 through 4 on the PCB), determine the analyzer's address. Switch positions 6, 7 and 8 are always ON ("1"). Figure 4-58 shows how to identify the address from the switch positions. Switch No.
When you set the No Analyzer switch ON, the front panel will communicate only with other GC’s; the front panel will not communicate with an attached analyzer. When the Lock Out Remote switch is ON, another front panel on the network cannot access this front panel, but this front panel can access other network front panels.

SOLENOID VALVES The PGC2000 uses two different types of solenoid valves in the Purge Air Panel, a vented type and a non-vented type (see Figure 4-65). Since these solenoids are not interchangeable, you must ensure that a replacement solenoid is the same type as the solenoid being replaced.
SECTION 5. MAINTENANCE PREVENTIVE MAINTENANCE The analyzer design eliminates the need for extensive and complex maintenance. Where preventive maintenance procedures require specific time frames or intervals, you should maintain an inspection log and inspection data. Figure 5-1 lists inspection routines, with recommended time intervals for each routine.

SECTION 6. TROUBLESHOOTING TROUBLESHOOTING GUIDELINES This section provides troubleshooting information by category. Included in this information are symptoms, causes, and suggested tests for further fault isolation. These tests are described in Section 7, listed by Test Procedure (TP) number. BASELINE PROBLEMS Baseline or Signal Offset (TCD) Symptom: Baseline (detector signal) is continually offset to the positive or the negative with no short term drift up or down scale (see Figure 6-1).
8. A continuous presence of sample at the detector due to sample valve leakage. Perform Test Procedure 3 (Sample Valve Leaking/Column Flooding). 9. Filament failure. Perform Test Procedure 6 (Filament TCD Test). Cyclic Short Term Drift Symptom: Baseline (detector signal) is experiencing a cyclic short term drift (see Figure 6-2) indicated by detector signal, graphics display, or strip chart recorder (if used).
Perform Test Procedure 3 (Sample Valve Leaking/Column Flooding); or Test Procedure 30 (Checking Temperature Table Values), steps 1 to 3, 8, and 9. Another possible cause could be detector filament deterioration. Baseline Continuous Noise Symptom: Baseline (detector signal) with no sample injection appears as noise similar in appearance to “grass”...
b. The gases may be pure, but contaminated tubing or hardware components in the analyzer or cylinder regulator(s) contaminate the makeup gases as they pass through them. The FID detects theses contaminants, resulting in a noisy baseline. c. An FID is generally equipped with a catalytic air cleanup unit to remove hydrocarbon impurities from the burner air.
Perform Test Procedure 11 (Common Usage of Gases), Test Procedure 13 (Burner Air Catalytic Cleanup Unit), or Test Procedure 14 (Coaxial Cable), as applicable. Replace or clean the FID (see "FID REPAIR" in Section 8). Signal Offset (FPD) NOTE Because of the sulfur addition in the FPD detector, the FPD will always have a background level.
a. Electrical noise from the FPD amplifier could result from a noisy power supply or defective component of the PCB. b. Loose electrical connections can cause electrical signals to be sporadic. c. Since the FPD amplifier input impedances are extremely high, low noise coaxial cable connects the detector and the FID amplifier.
5. Baseline offset extreme. See "Baseline or Signal Offset (TCD)" or "Baseline or Signal Offset (FID)." 6. Column broken or connection in the column train disconnected. Perform Test Procedure 7 (Column Train Problems). 7. TCD Failure. Perform Test Procedure 5 (TC Detector Balance) and Test Procedure 6 (Filament TCD Test), as applicable.
Additional Peaks of Unknown Origin (Mystery Peaks) Symptom: Chromatograph displays extra peaks or a noted difference in composite chromatograph appearance from that of the calibration (see Figure 6-10). Unknown TIME TIME NORMAL MYSTERY PEAKS Figure 6-10. MYSTERY PEAKS Cause: If only present on calibration sample and not on process, verify that the correct calibration and proto fuel samples are being analyzed.
above the bubble point of the sample, the sample will bubble in the sample chamber, causing an inconsistent liquid fill of the sample loop. This results in a continuously variable sample size. A defective sample valve stem or leaking seal(s) can also cause nonrepeatability. Perform Test Procedure 20 (Variable Sample Size).
Cause: The gating in the method needs to be modified to ensure gating of the missing peak in the report. This can be done by modifying the gate ON/OFF time in the method table. See "PEAK DETECTION" in Section 4 for detailed instructions. Peak Inversion Symptom: The peaks on the strip chart recorder are reversed or negative (see Figure 6-13).
The peaks may in fact be too large and saturating the detector or column. The splitter may be out of adjustment, or the liquid sample size may be too large. Possibly the detector gain jumper at the detector electronics is not setup correctly. The sample valve may be injecting an excessively large sample volume due to deformation or a scratch in sample stem or worn seals.
Peak Discrimination Symptom: Discrimination is the non linear unequal dilution of hydrocarbons in the column train. Typically the heavier components will tend to dilute more than the lighter components. Cause: Discrimination is usually the result of a leak or incorrectly adjusted sample splitter. The leak or split might cause more of the heavier components to be exhausted out the splitter vent or leak exit than the lighter components;...

CAUTION See "AIR PURGING" in Section 4 for the override function. Do not perform override until you have read Section 4 completely and you understand and can perform the procedure requirements. Install a temperature monitor and verify ambient temperature. Ensure air flow into the Controller housing.
CAUTION See "AIR PURGING" in Section 4 for the override function. Do not perform override until you have read Section 4 completely and you understand and can perform the procedure requirements. The temperature controllers must be stable with respect to tracking the set point. Symptom: The actual temperature is not stabilizing at the set point temperature.
Low Oven Temperature CAUTION It is the customer’s responsibility to ensure that the area is safe and and hazard- free, and will remain so the entire time the analyzer is open. This responsibility includes ensuring adequate ventilation in analyzer shelter and obtaining proper work permits, etc.
2. Air supply pressure is low. Verify correct air pressures. If necessary make adjustment. 3. Vortex cooler not adjusted. Perform Test Procedure 41 (Programmed Temperature Oven Cool Down). 4. Listen for cool down solenoid to operate and introduce increased vortex cooler air flow. If this does not happen, perform Test Procedure 41 (Programmed Temperature Oven Cool Down).
No Analyzer Keypad Response Symptom: Pressing keypad on analyzer front panel produces no response on CRT or other analyzer output. Cause: No response by keypad could indicate defective keypad or malfunction or defect in keypad cabling from keypad to keypad assembly PCB. The CRT Control PCB or associated wiring or connections may be defective.
6. Replace LOCOM PCB (set-up address switch). Symptom: Cannot contact or use remote networking feature. Cause: Previous remote communication was not terminated. 7. Search for analyzer that is accessing another remote, or that is itself being accessed, then terminate the access. See "REMOTE GC OPERATION OPTION"...
Low Carrier Pressure Hardware Alarm Symptom: Low carrier gas alarm. If carrier is in short supply and not corrected, carrier flow rates will reduce as the gas is depleted. Analyzer data will become erroneous as carrier pressure drops below the analyzer requirement. Causes: The following can be causes for low carrier pressure alarm.
Symptom: If X purge system is installed, analyzer power will be removed and cannot be restored until purge air is restored. Causes: The following can be the causes of loss of purge. 1. Air supply to analyzer has been shut off. Perform Test Procedure 1 (Carrier, Makeup, and Utility Gas Supplies).
Page 197
Cause: Possible causes for analyzer not powering up are as follows: 1. If attempting to Override X-Purge, light intensity may not be sufficient to energize Override, or cover to X-Purge electronics housing is not removed. 2. Power is disconnected. Check power distribution circuit breakers and local disconnect switch. (Watch for lock-out tag-out).
ELECTRONIC PRESSURE CONTROL TROUBLESHOOTING The Pressure Control Assembly (see Figure 6-15) requires special tools and equipment for repair. If you suspect a problem with this assembly please contact your ABB service representative. Figure 6-15. EPC PRESSURE CONTROL ASSEMBLY 6-28 2000-OSM, F1...

4. Leak check every connection outside the analyzer on the entire carrier flow path. Perform step 5 only after step 4 has been completed and all leaks are repaired. 5. Loosen inlet fitting nut and check for presence of carrier or makeup gas using a leak detector solution.
CAUTION See "AIR PURGING" in Section 4 for the override function. Do not perform override until you have read Section 4 completely and you understand and can perform the procedure requirements. 1. Stop Analysis at the end of the current analysis cycle, and make no sample injection until procedure is completed.
1. Stop Analysis at the end of the analysis and make no sample injection until procedure is completed. 2. Reduce isothermal and programmed temperature oven air temperatures by reducing oven air pressures to zero psig. 3. Open Isothermal oven. 4. Inspect for disconnected or loose tubing connections or broken column in the column train from the carrier regulator outlet to the column vent.
2. Perform Test Procedure 30 (Checking Temperature Table Values) and Test Procedure 9 (Baseline Cyclic Carrier Regulator), as applicable. TP 11: COMMON USAGE OF GASES 1. Are other analyzers serviced from the same burner air, carrier, or burner fuel source, experiencing noise? If Yes, then the noise problem is most likely related to a common utility gas, tubing, fitting, or regulator.
2. Gently move or touch coaxial cable, while monitoring detector output on recorder. Some movement of signal is normal, but spikes of noise should not occur. 3. If noise spikes are systematically generated, check the coaxial cable connections. 4. If the connections are correct and tight, replace coaxial cable. TP 15: FID REDUCED SENSITIVITY CAUTION It is the customer’s responsibility to ensure that the area is safe and and hazard-...
TP 16: FID WILL NOT LIGHT CAUTION Do not ignite the FID flame if the temperature is below operational level. Low oven temperature will result in condensation damage to the flame cell. 1. Ensure burner air and burner fuel are adjusted to the values shown on application data sheets. 2.
1. Disconnect the cell vent and hold a reflective surface such as a mirror, wrench or other suitable object at such an angle that you can see the reflective surface. 2. If the flame is ignited, you will be able to see the condensed water vapor form on the reflective surface.
14. Remove power and disconnect the cable between J9A and J9. Check continuity between J9A terminals 1, 2, and 3 and J9 terminals 1, 2, and 3, respectively. If any wires are open replace the cable, apply power and repeat step 11. 15.
4. Compare the temperature zone temperatures with those of your application data sheets sent with your chromatograph. Perform Test Procedure 30 (Checking Temperature Table Values) and make any necessary table corrections. Bubbles at the sample valve effluent generally indicate the sample temperature is above the bubble point of the sample. Carrier gas displacement of sample stem groove volume may be occurring due to leaking valve seals, causing varying sample size.

Backplane PCB The Controller Backplane PCB has six jumpers to set up (see Figure 8-27). Figure 8-27. BACKPLANE PCB JUMPER LOCATIONS Jumpers JP1 and JP5 are used to bypass pressure switch connection points for certain analyzer configurations. Since the purge switches are daisy chained in series, it is necessary to jumper across switches that are not connected.
• Revision E or later: the shunt goes between pins 1 and 2 for normal operation (a Chroma I/O PCB dedicated to a single detector amplifier); the shunt is installed between pins 2 and 3 when the outputs of two detector amplifiers are applied to a single Chroma I/O PCB. DTC Backplane PCB The Digital Temperature Controller (DTC) PCB has eight jumpers and one switch to set up (see Figure 8-28 for location).
JP1 is the service diagnostics jumper. For normal operation the shunt is installed between pins 1 and 2. For service diagnostic screen use (only) the shunt is installed between pins 2 and 3. After servicing, the shunt must be reinstalled between pins 1 and 2. JP4 is the VAC Conditioning Board jumper.
VAC Conditioning PCB There can be either one or two VAC Conditioning PCBs, depending on the application. Each board has two jumpers to be set, JP4 and JP5 (see Figure 8-30). These jumpers are set according to the voltage supplied to the board, as follows (JP4 is the hot side and JP5 is the neutral side): Applied Voltage JP4 Shunt JP5 Shunt...
FID Amplifier PCB The jumper on this PCB relates to intercolumn detector usage. For normal operation shunts should be installed in the first two positions at the right side of J18. These shunts are removed for an application using intercolumn detectors (see Figure 8-32). Figure 8-32.
The carrier jumper is normally connected between WT9 and WT10 (single carrier). For dual carrier applications this jumper is connected between WT7 and WT8. The temperature jumpers are normally connected between WT1 and WT2 and between WT4 and WT5 (low temperature). For high temperature applications these jumpers are connected between WT1 and WT3 and between WT4 and WT6.
EPC Multibus PCB This board has one jumper and one switch to set up (see Figure 8-35). JP1 is the service diagnostics jumper. For normal operation the shunt is installed between pins 1 and 2. For installation and service the shunt is installed between pins 2 and 3. After installation or service, the shunt must be reinstalled between pins 1 and 2.
Chroma I/O PCB (old type) CAUTION This board can only be used when the analyzer also has the old type Single Board Computer PCB (identified by a toggle Reset switch). This board, part number 3528515-2, has two jumpers which are mutually exclusive. When there is only one Chroma I/O PCB in the analyzer, or the board is used as Chroma I/O PCB #1 in a simultaneous dual detector analyzer, the jumper will be located between the terminals of JP1 (see Figure 8-37).
JP1: When there is only one Chroma I/O PCB in the analyzer, or the board is used as Chroma I/O PCB #1 in a simultaneous dual detector analyzer, the shunt is installed between pins 1 and 2. When the board is used as Chroma I/O PCB #2, the shunt is installed between pins 2 and 3. JP2 through JP6: These jumpers are installed between pins 2 and 3 on the Chroma I/O PCB (later revisions of this board will have the jumpers hard-wired).

DUAL AIR CLEANUP ASSEMBLY CAUTION It is the customer’s responsibility to ensure that the area is safe and and hazard- free, and will remain so the entire time the analyzer is open.
2. Turn off oven air to the isothermal oven and allow all temperature zones to cool. 3. Turn off air supply to air cleanup unit. 4. Open the isothermal oven door. 5. Label the tubing on both sides of the associated unions with temporary numbered tape labels. The labels are later used to ensure correct tubing connections when the air cleanup is reinstalled.
Installing the Air Cleanup Tubes 1. To install an air cleanup tube, insert the short end of the catalytic air tube through the larger tube passage of the body and align it with the inside air inlet port connection of the top cap. 2.
2. Connect the tube connections to their respective reducing unions while matching the numbers on the temporary labels. 3. Remove the temporary tape labels. 4. Apply carrier and air to the air cleanup assembly. 5. Using a liquid leak detection solution, test for leaks and make necessary repairs before proceeding.
11. The temperature of the air cleanup assembly can also be monitored from this screen. The time required to achieve stability is two hours. 12. Press the F1 soft key as necessary to return to the Background screen. Air Cleanup Final Preparation 1.
CAUTION See “AIR PURGING” in Section 4 for the X Purge override function. Do not perform override until you have read Section 4 completely and you understand and can perform the procedure properly. NOTE To ensure the integrity of the components within the CP Valve, use the tools in CP Valve Tool Kit 754K003-1 when assembling or disassembling the CP Valve.

SECTION 10. VISTA BASIC INTRODUCTION Vista BASIC is for the user familiar with the fundamentals of BASIC programming languages and general programming techniques. This information is provided for reference only, not as a tool for teaching BASIC programming. "ALPHABETIC LISTING" lists the Vista BASIC commands, functions and statements in alphabetical order, with descriptive information included in each listing.
• The maximum number of programs allowed is 8. In each program, • the maximum number of source program lines allowed is 50; • the maximum number of variables allowed is 49; • the maximum number of characters allowed in a string is 255; •...
For exponential form floating point numbers, a fixed point constant is followed by the letter E and an optionally signed integer with no blanks separating them. Numbers between 0 and 1.0E ±38 approximately can be represented. Negative values are indicated with the unary negation operator (-). Examples of valid floating point constants are: 0.123 -10.123...
and those values can then be accessed by another BASIC program. Thus, the COMMON! array is a mechanism whereby information and data values can be passed between BASIC programs. Another characteristic of the COMMON! array is that the memory allocation is static. That is, the COMMON! array stays around forever and the values are retained between program modifications and compilations.
