WARNING: POSSIBLE EXPLOSION HAZARD

This equipment is used in the analysis of sample gases which may be flammable, and the burner fuel used in the ionization process IS flammable. A system of intrinsically safe electronics and an explosion proof tower are used to prevent any ignition of a flammable gas leak. For this to be effective, the module MUST be placed in a well-ventilated area, with unobstructed air flow around it.

DO NOT place it within another enclosure without assuring this ventilation. DO NOT obstruct the vent holes on the top and sides of the module. DO NOT place the FID module within another enclosure unless the latter has a

guaranteed air circulation such as to dilute a worst case fuel or sample leak below 25% of the LEL. Doing so will negate the safety features and may result in an explosion, serious injury, property damage and death.

WARNING: FLAMMABLE SAMPLES

Consult the factory if flammable samples will be measured.

WARNING: PARTS INTEGRITY

Tampering with or unauthorized substitution of components may adversely affect safety of this product. Use only factory-approved components for repair.

WARNING: POSSIBLE EXPLOSION HAZARD

Ensure that all gas connections are made as labeled and are leak free. Improper gas connections could result in explosion and death.

UICK STARTUP PROCEDURE

The purpose of this reference guide is to provide a easy to follow, step by step procedure through initial start up and ignition of the FID2 Analyzer Module. This procedure assumes that the customer has already made all necessary electrical and gas connections and established the proper network connections.

1. Turn on power to the instrument. The #1 LED (POWER) will illuminate. The #3 LED (BLOCK) will begin flas hing.

2. If sample gas has been connected and the sample pressure to the analyzer is sufficient to provide an accurate reading, the #4 LED (SAMPLE) will be illumninated.

3. Allow the analyzer module to warm up and the burner block temperature to reach the proper minimum ignition temperature (50°C). When the burner block temperature reaches the minimum ignition temperature, the #5 LED (IGNITE OK) will come on.

4. The instrument is now ready to be lit. Lighting the burner can be conducted in one of two methods: a) manual ignition from the front panel of the Analyzer Module or b) autoignite from the Platform.

a) To light the instrument from the Analyzer Module, hold the "FUEL

OVERRIDE/IGNITE" switch (located to the left of the indicator lights) in the up (FUEL OVERRIDE) position for 30 seconds. Immediately move the switch to the down (IGNITE) position. The "IGNITE" mode is automatically set to stay on for a preset time period and does not require the switch to be held down. If the lighting procedure was successful, the #2 LED (FLAME) will begin flashing as the flame temperature rises to the correct operating temperature. Once this LED becomes solidly lit, the flame has reached operating temperature.

b) To light the instrument from the Platform using the autoignite mode, simply

press the "light" softkey shown in the "Light Flame" menu of the Platform. The Analyzer Module will begin to go through an automated sequence of enrichment and ignition similar to the manual mode described in step 5. If the burner fails to light on the first try, the Analyzer Module will perform 2 more tries before terminating the autoignite sequence. If the Analyzer Module fails to light after 3 attem pts, an erro r me ssage will be displa yed sho wing th e cau se o f the fault.

5. If the burner fails to light, check all gas connections for proper gas composition and pressure, block temperature, and outlets for obstructions. Repeat step 4.

6. If the flame is lit, the #2 LED will begin f lashing. Once the flame temperature has reached the correct operating temperature, the LED will remain on solid.

7. If the fuel and air pressures and ratios are within proper operating parameters to support a continuous flame operation, the #6 LED (FUEL/AIR) will illuminate. This light will not be on before or during fla me ignition.

8. Once the burner block temperature reaches the control temperature of 80°C, the #3 LED will stay on solid.

9. If the instrument has been successfully lit, the temperatures are up to proper operating levels, and the fuel, air, and sample gases are properly adjusted to support the flame and achieve reliable results, all 6 indicator lights will be lit solid.

The unit is now ready for calibration or burner optimization.

This manual describes the Flame Ionization Detector (FID 2) Analyzer Module of Rosemount Analytical's NGA 2000 Series of gas analysis components. See Figure 1-

1. The FID 2 Analyzer Module is designed to use a flame ionization technique to

measure the total concentration of hydrocarbon (including certain oxygenated hydrocarbons) components within the sample stream.

The entire FID 2 Analyzer Module is designed as a module with electrical connections at its front, and gas connections made from the rear. All electronics relative to sample control and signal conditioning are included in this module.

1.2 TYPICAL APPLICATIONS

Typical applications for the FID 2 Analyzer Module include:

• The monitoring of atmospheric air for low-level total hydrocarbon contaminants

• Determining the total hydrocarbon content of exhaust emissions from internal

combustion engines

• Carbon bed monitoring

• Determining the total hydrocarbons content of process and product gases from

air separation plants

1.3 THEORY OF TECHNOLOGY

This Analyzer Module uses the flame ionization method of detection. The sensor is a burner in which a regulated flow of gas sample passes through a flame sustained by regulated flows of a fuel gas (hydrogen or a hydrogen/diluent mixture) and air.

Within the flame, the hydrocarbon components of the sample stream undergo a complex ionization that produces electrons and positive ions. Polarized electrodes collect these ions, causing current to flow through an electronic measuring circuit.

The ionization current is proportional to the rate at which carbon atoms enter the burner, and is therefore a measure of the concentration of hydrocarbons in the sample.

1.4 GAS SAFETY FEATURES

The FID 2 module is divided into two parts - a pneumatic section and an electronic section. The two sections are separated by a pair of solid partitions to prevent any leak of gas in the pneumatic section from reaching the electronics. The electrical

748364-D Rosemount Analytical November 1998

NTRODUCTION

connections into the pneumatic section are made intrinsically safe by a series of overvoltage protection devices and current limiting resistors. The burner itself is an explosion-proof assembly. The combination of these two techniques allows the analyzer to meet international safety standards without the use of an expensive continuous-dilution purge - but ONLY when it is installed in a general purpose area with good air circulation.

WARNING: POSSIBLE EXPLOSION HAZARD

Hydrocarbon concentration(s) in the sample gas must be below the Lower Explosion Limit (LEL).

All tubing ahead of the burner is rigid m etallic tubing assembled with ferrule/nut type compression fittings. However, should an internal fuel leak occur, a worst-case leak would be dissipated below 25% of the LEL of hydrogen by natural dilution outside of the pneumatic section before it could be ignited by any external ignition source, and there is nothing within the pneumatic section to ignite it.

The FID 2 is designed to use 100% hydrogen fuel or 40% H2/60% He fuel at a maximum inlet pressure of 3446 hPa-gauge (50 psig). A different flow restrictor is used for each fuel type1.

WARNING: POSSIBLE EXPLOSION HAZARD

Protection against explosion depends upon a special fuel flow restrictor1 at the fuel inlet. DO NOT REMOVE THE FUEL INLET RESTRICTOR.

1.5 FUEL GAS OPTION

The standard FID 2 Analyzer Module requires 40% hydrogen/60% helium burner fuel gas. As an option, the analyzer module can be equipped to use 100% hydrogen fuel. The particular application and characteristics of the sample gas to be measured will dictate the preferred type of fuel. The following guidelines can be used for determining fuel gas type:

For measuring low-level hydrocarbons in ambient air or in other sample gas with relatively constant oxygen content, 100% hydrogen is preferable. It provides the highest obtainable sensitivity and maximum stability.

The fuel restrictor is part of the Flow Control Manifold Assembly, which is specific to an application.

NTRODUCTION

For monitoring internal combustion exhaust emissions or other sample gas with varying oxygen content, mixed fuel is preferable. In fact, a hydrogen/helium mixture is more desirable than a hydrogen/nitrogen mixture. With this type of sample, the use of mixed fuel gas minimizes the error introduced by oxygen synergism.

Changes in the burner air flow rate have little effect on signal strength. For a given flow, the signal can be optimized by adjusting the fuel flow rate.

NSTALLATION

2.1 UNPACKING

When the FID 2 Analyzer Module is received, carefully examine the shipping carton and contents for signs of damage. Immediately notify the shipping carrier if the carton or contents is damaged. Retain the carton and packing material until all components associated with the Analyzer Module are operational.

2.2 ASSEMBLY

The FID 2 analyzer module MUST NOT be placed within a conventional NGA platform, single module enclosure or dual module enclosure since the latter would not allow free flow of air around the module, thus violating its safety certification. The enclosure is designed so that this would be very hard to do anyway.

There is a special platform specifically designed to accept this module; consult the factory for details.

Install the Platform and I/O Module(s) according to guidelines in the Platform manual.

2.3 LOCATION

WARNING: POSSIBLE EXPLOSION HAZARD

Do not place the FID 2 module within another enclosure unless the latter has a guaranteed air circulation such as to dilute a worst case fuel or sample leak below 25% of the LEL. Failure to will negate the safety features and may result in explosion, serious injury, material damage and death. Also, do not cover the vent holes on the top and sides of the module.

Install the Analyzer Module in a clean, weather-proofed, non-hazardous, vibration-free location free from extreme temperature variations. For best results, install the Analyzer Module near the sample stream to minimize sample transport time.

Operating ambient temperature is 5 °C to 40 °C, limited to temperature changes of less than 10 °C/hr. Acceptable dew point range is less than 95% relative humidity, but not in excess of 40°C wet bulb temperature.

748364-D Rosemount Analytical November 1998

NGA 2000 FID 2 Analyzer Module

NSTALLATION

The cylinders of fuel, air, and calibration gases should be located in an area of relatively constant ambient temperature.

2.4 GASES

During normal operation, the Analyzer Module requires fuel and air to maintain the burner flame as well as suitable standard gases for. Refer to the criteria for selection of these gases in Section 2.4.2.

After initial startup or after startup following a prolonged shutdown, the analyzer may display baseline drift for a considerable period of time, particularly on the most sensitive range.

Commonly, the drift is caused by small amounts of organics (such as hydrocarbons) in the inner walls of the tubing in both the internal flow system and the external gas supply system. Drift results from any factor influencing the equilibrium of these adsorbed hydrocarbons, such as temperature or pressure. Hydrocarbons adsorbed within the analyzer in the gas passageways (or in th e fuel or air lines) will elevate the overall baseline.

Note that this type of drift occurs only when the flame is burning. If drift occurs when the flame is extinguished, the electronic circuitry is at fault or the burner or cabling is contaminated with a conductive film. To minimize drift, use clean fuel and air, keep the analyzer clean, and locate the gas cylinders in an area of relatively constant ambient temperature.

The cylinders supplying all gases each should be equipped with a clean, hydrocarbonfree, two-stage regulator and a shutoff valve.

All new external gas tubing (except for SAMPLE BYPASS) is strongly recommended, preferably pre-cleaned, stainless steel, gas chromatograph-grade tubing. Thoroughly clean before use (if a hydrocarbon-based cleaning solvent such as acetone is used, purge tubing with dry nitrogen or helium for several minutes before using.)

Gas line connections are compression fittings. Do not use pipe thread tape on such fittings.

Since the oxidation of hydrogen is accompanied by the formation of water vapor, the exhaust tubing always should be slanted downward at least 6 degrees from horizontal. Otherwise, water may accumulate in the line, causing back pressure and noisy readings, or may back up in the line and flood the burner.

If the sample is toxic or noxious, or is to be reclaimed, connect the Bypass outlet to a suitable disposal system. Do not use any device that may cause back pressure in the line.

AS SPECIFICATIONS

Fuel Gas — Standard analysis usually requires mixed fuel, i.e., 40% (±2 %) hydrogen and 60% helium. H2/He mixed fuel is recommended over H2/N2 fuel because of better linearity in concentration output. Such blends are supplied by many gas vendors specifically for this use, with a guaranteed maximum total hydrocarbon content of 0.5 ppm, measured as methane. This specification should be used when obtaining these mixtures.

Note: The Analyzer fuel inlet restrictor fitting and Detector fuel gas capillary inlet are

marked with white dots for pure hydrogen fuel applications and with green dots for mixed fuel applications.

Note: Some applications require the use of 100% hydrogen fuel. When using this

option, always ensure that sample gas pressure (4 to 5 psig) is present when fuel flow is present. Otherwise, the flame tip may be damaged.

Burner Air — In order to ensure a low background signal, hydrocarbon free grade air

with less than 1 ppm maximum total hydrocarbon content is highly recommended. An alternative source for burner air and zero gas (see CALIBRATION GASES below) is a combination diaphragm pump and heated palladium catalyst. This process continuously removes moderate amounts of hydrocarbons and carbon monoxide from ambient air.

Calibration Gases — Calibration method and gases depends on the type of fuel gas used, the operating range, and the desired measurement accuracy. In all methods, zero and span gases are used, and are introduced through the sample inlet at the rear of the module.

Zero Gas  It is recommended that the gas should have a composition as close to the background composition of the sample as possible.

Span Gas



Span gas consists of a specified concentration of methane and other

hydrocarbons in a background gas such as nitrogen.

Sample Gas — Sample gas must be nonflammable (below 100% of the sample's LEL).

Flow Rate — The sample flow rate must be between 0.5 L/min. and 2 L/min. Pressure/Filtration — See Table 2-1 for input pressure specifications.

Noncompliance with these specifications could cause over-pressure damage to the module.

All internal pressure settings are preset at the factory, but the operator should check for accuracy. It is essential that the sample be filtered for particulates down to 0.1 microns. A suitable filter is the Balston type 95S6 with 0.1 micron filter element. It should normally be replaced on a two week schedule, depending on the sample.

Leak Test — The Analyzer Module is completely tested at the factory for gas leakage. The user is responsible for testing for leakage at the inlet and outlet fittings on the rear panel. The user is also responsible for internal leak testing periodically and if any internal pneumatic components are adjusted or replaced (with a test procedure chosen by the user).

2.5 ELECTRICAL CONNECTIONS

Note Electrical installation must be in compliance with National Electrical Code

(NEC/NFPA 70) and/or any state or local codes.

Two electrical connections are required on the Analyzer Module: POWER and NETWORK. See Figure 2-3. On the Analyzer Module, two NETWORK connectors are available, either of which is appropriate for: 1) interconnection with the Back plane of the Platform or 2) "daisy-chaining" with other NGA 2000 components, or 3) connection to a PC via a suitable LONTALK adapter and software such as the NGA DDE server and client. Connect Analyzer Module POWER to Back plane POWER or external 24 VDC power source.

TARTUP AND OPERATION

11. Auto-ignite the flame. The Flame LED should then be continuously illuminated when the flame is successfully lit.

Auto-ignition provides fuel override and three attempted ignitions (default setting), if necessary.

Before ignition and operation, Fuel Flow must be set to ON in "Light Flame" display screen under Basic Controls.

The front panel ignition switch must be manipulated in the following ways: a. Press up and hold for 30 seconds. This puts the system into the enriched

mode, with lower air flow. b. Press down to turn on the burner glow plug for up to 10 seconds. c. Repeat as necessary (if fuel and air sources are farther away than 10 feet,

several more attempts may be necessary).

Flame on is defined as true when the flame temperature is greater than the

block temperature by the amount contained in the variable FLAME_DELTA. d. If the flame has been lit, but the flame temperature increases slowly, perform

the following steps:

1) After igniting flame, wait for 2 seconds.

2) Press switch down momentarily.

3) Repeat release switch, wait and press down steps as necessary.

12. Check and re-adjust the internal pressures if required. The Fuel/Air light must be lit for proper operation.

13. The unit is now ready for first binding as described in Section 3.5, and then optimization as described below.

3.4 OPTIMIZATION PROCEDURE

Although the module has been set up for best operation at the factory, settings can change and your application may be different. The following shows how to optimize the operation of the FID 2 for your application.

1. Ignite the flame of the FID 2 using the startup procedure as above.

2. Verify that the mixed fuel supply pressure at the Analyzer’s rear panel bulkhead is between 49 and 50 psig.

3. Allow the Analyzer module response to stabilize. Typically allow 1 to 4 hours.

4. Select the desired range to optimize. For best results use a span gas with a concentration of 100 ppm CH4 or greater. This will minimize the effects of the THC contamination in the fuel and burner air supply.

5. Set the internal sample pressure to the desired operating level. The sample pressure must be kept constant throughout the optimization procedure.

6. Set the internal burner air pressure to between 965 to 1103 hPa-gauge (14 to 16 psig). The burner air pressure must be kept constant throughout the optimization procedure.

7. Set the internal fuel pressure to 345 hPa-gauge (5 psig). Calibrate the instrument as stated below.

8. Introduce the span gas and monitor the reading until it is stable. Increase the internal fuel supply setting in the following sequence: 600 hPa-gauge (8.7 psig), 625 hPa-gauge (9.1 psig), 650 hPa-gauge (9.4 psig), 675 hPa-gauge (9.8 psig), 700 hPa-gauge (10.1 psig), and 725 hPa-gauge (10.5 psig). Monitor the reading at each fuel pressure setting. Wait at least 2 minutes between fuel setting changes. Record all the readings.

9. Review the readings for each fuel pressure setting. Select the fuel pressure setting that produces a reading that is within 1% from the maximum. For this condition the FID 2 is operating at its optimized plateau.

3.5 BINDING

To achieve full coordination between Analyzer Modules and associated I/O Modules, the user must bind those components together in the System Set Up portion of the Technical Configuration Menu in software. (See the Platform manual for binding instructions.)

Note If binding is attempted after ignition, the flame may be extinguished. If this

occurs, it must be re-ignited.

3.7 CALIBRATION DETAILS

The range change resistor in the preamp has some effect on the way the spans work. In most NGA analyzers it is possible to make them zero and span all ranges together or separately. If this option is selected, the analyzer attempts to determine if a zero or span is appropriate using the supplied zero and span gases, and if the gases are suitable it will go ahead and zero or span as many ranges as it can. The FID 2 however may switch gains between ranges, and if so it will not be able to zero or span the ranges on the other side of the switching point.

The switching point is determined by a number of factors, including the gas response factor, the sample pressure, the type of fuel and the capillary use d. In general it will occur at about 600ppm of methane on a low range instrument. This means that if the ranges are set at 10, 100, 1000, 5000, the analyzer will be able to span the lower two, or the higher two at once, but not all four.

Generally, it is best to operate the analyzer on a single range and calibrate that, or to calibrate the ranges individually.

If the user is unable to calibrate the Analyzer Module (i.e., when ZERO or SPAN is initiated, nothing happens), several possible solutions may be tried. One solution relates to the use of an incorrect gas for zeroing or spanning (e.g., using a high concentration gas to zero or a zero gas to span the Analyzer Module). Simply recalibrating with the appropriate gas(es) may not correct the problem because the ZERO OFFSET or SPAN FACTOR has been set to an extreme value in the process.

To remedy the problem, do the following:

1. Verify that correct zero and span calibration gases are being used properly. If so, attempt to recalibrate according to instructions at the beginning of the previous section, ensuring that case temperature and displayed measurement reading are stable before initiating the calibration routine. If incorrect gases were used in the initial, failed calibration, skip to Step 2.

2. Make the following selections from the Main Menu: Expert Controls and Setup,

Analyzer Module Setup, then Calibration Parameters. Disable Calibration Adjustment Limits.

3. Recalibrate the analyzer module according to instructions at the beginning of the previous section, ensuring that case temperature and displayed measurement reading are stable before initiating the calibration routine.

3-12

4. Enable Calibration Adjustment Limits in the Calibration Parameters menu.

TARTUP AND OPERATION

3.8 ROUTINE OPERATION

After binding and calibration, proceed as follows: Supply sample gas to the SAMPLE INLET. Adjust external flow controller or throttle

valve so that flow discharged from the BYPASS outlet is between 0.5 and 1.0 L/min. The reading on the SAMPLE pressure gauge should be the same as that used during adjustment of the span control. Adjust, if necessary.

Adjust the Range Number setting. If maximum sensitivity is required from the FID 2 Analyzer Module, use an optimum

combination of settings on the SAMPLE, FUEL, and AIR pressure controllers. Settings must be determined experimentally, but the curves in Figures 3-7, 3-8 and 3-9 may be used as guides for the FID 2 optimization procedur e abov e.

The Analyzer Module will not allow the user to increase the upper limit of a range beyond the "maximum range" software setting. To change the "maximum range" value, select the following from the Main Menu: Technical Configuration Menu, Service

Menus, Manufacturing Data, and Analyzer Manufacturing Data. Select Minimum/maximum ranges and tags… and then Maximum Range, and use the arrow

During shutdown, always turn off fuel gas first, then the air and sample gases. The flame can also be turned off by setting Ignition System Enable to "Off" in the Light Flame menu (under Basic Controls). Subsequently, remember to set Ignition System Enable to "On" before attempting to ignite the flame.

After initial startup, or startup following a prolonged shutdown, the Analyzer Module requires about one day's continuous operation to stabilize. For several days afterwards, calibrate daily. The frequency of subsequent calibrations can be reduced as experience dictates, consistent with the accuracy requirements of the particular application.

TARTUP AND OPERATION

3.9 SHUT DOWN PROCEDURE

If the FID 2 is to be left in the powered down state for any length of time greater than a few hours, it is important that the flame tower be dried out before it cools off. This is to avoid condensation causing corrosion. If the sample contains halogenated compounds this is even more important.

Flush the flame tower with burner air for around an hour after the flame has been turned off. Simply leave the burner air flowing. When no evidence of condensation can be seen in the exhaust tubing, it is safe to switch off the FID 2 power.

If this precaution is not taken, corrosion can occur making it hard or impossible to light the flame.

3.10 SAFETY SYSTEM

The FID 2 Analyzer Module safety system is entirely passive. The pneumatic section of the analyzer is designed to be intrinsically safe, except for the flame tower itself which is designed to be explosion proof. Intrinsic safety design ensures that any energy released in the hazardous area (the pneumatic section) will not be enough to ignite any hydrogen that may have leaked. This is achieved by limiting the voltage and the current in all the circuitry that enters this area. It is therefore essential that NO modifications are done to the circuit boards. Any repairs should be performed at the factory where the correct components will be used.

The flame tower is designed to be explosion proof. This is achieved by careful control of the spacing and clearances of the assembly, and the presence of the various flow restrictive devices and the outlet flame arrestor. It is essential that no changes be

made to this device that can impact any of these clearances, and thus that any repairs of the device are such as to maintain its designed clearances. It is

recommended that any repairs of the flame tower be performed in the factory or at other authorized Rosemount service centers.

A temperature safety system activates when the burner flame temperature exceeds 225

message on t he light flame menu screen. After cooling to below 225°C, the unit can be re-ignited normally. Verify that the proper fuel is being used. Do not use H2 in

a unit configured for mixed fuel.

Since the proper methane – non-methane process should be run under 200°C, you should not experience this failure mode. If it occurs, contact Rosemount Analytical factory service.

AS SAFETY FEATURES

A.1 GAS SAFETY FEATURES

The NGA 2000 Flame Ionization Detector Analysis Module is designed to meet international safety standards in accordance with IEC 1010 and other related documents. The gas handling part of the module is designed to be intrinsically safe, other than the flame tower which is explosion proof (Ex"i" and Ex"d" respectively)

The standard module is only equipped to analyze a non-flammable sample, below 100% of the lower flammable limit.

WARNING: POSSIBLE EXPLOSION HAZARD

Protection against explosion depends upon a special fuel flow limiting restrictor in fuel inlet fitting. Do not remove fuel inlet restrictor. Use the correct fuel flow limiting restrictor for the fuel being used. Do not use 100% hydrogen fuel in a 40% H2/60% He configured Analysis Module. Replace only with factory supplied fitting.

A.2 FUEL GAS OPTION

For the burner fuel gas, the standard analyzer requires 40% hydrogen and 60% helium. Through the selection of the hydrogen fuel option, the analyzer can be equipped to use 100% hydrogen fuel. This factory installed option can be ordered as a matrix item.

The preferred type of fuel depends on the particular application and the characteristics of the sample gas:

For measuring low-level hydrocarbons in ambient air, or in other sample gas with relatively constant oxygen content, 100% hydrogen is preferable. It provides the highest obtainable sensitivity and the maximum stability. Zero drift caused by ambient temperature variations of the fuel cylinder is somewhat lower for 100% hydrogen than for mixed fuel. (With either fuel, it is desirable to maintain cylinder temperature constant.)

748364-D Rosemount Analytical November 1998

NGA 2000 FID 2 Analyzer Module

A-1

PPENDIX

AS SAFETY FEATURES

A. G

For monitoring vehicular exhaust emissions, or other sample gas with varying oxygen content, mixed fuel is preferable; and a hydrogen/helium mixture is more desirable than a hydrogen/nitrogen mixture. With this type of sample, the use of mixed fuel gas minimizes the error introduced by oxygen synergism.

An effective way to reduce the effect of internal oxygen is to dilute it with an inert gas. This might be accomplished by a constant dilution of sample and calibration gases ahead of the burner but it is simpler and more accurate to provide that diluent in the form of premixed fuel. Both nitrogen and helium have been used as a diluent, but helium has proven to be most effective in improving the equality of response to the various species of hydrocarbons.

As indicated earlier the flame output signal is optimum when the ratio of hydrogen flow to inert flow is about 40/60; therefore, this is the chosen composition for hydrogen/helium premixed fuel.

The sample flow is kept low to maximize the dilution effect while still providing adequate sensitivity. The burner air flow is normally about four times the fuel flow, and changes have little effect on signal strength. For a given flow, the signal can be optimized by adjusting the fuel flow rate.

YPICAL FLOW RATES WITH PREMIXED FUEL

It is worth noting that with a 40/60 premixed fuel, the above flows amount to 40 cc (8%) hydrogen, 67 cc (13%) inert plus sample and 400 cc (79%) air, which compare closely to the 30 cc (8%) hydrogen, 45 cc (12%) sample and 300 cc (80%) air given earlier for straight hydrogen fuel.

Since the sample flow in the case of mixed fuel operation is only about one-sixth of that with straight hydrogen fuel, it is clear that higher sensitivity is obtained with straight hydrogen fuel operation. However, in any application where the sample contains more than one species of hydrocarbon and/or a varying concentration of oxygen, the mixed fuel operatio n shoul d be used .

The mixed fuel is recommended, not only for sample containing variable concentrations of oxygen, but also for a specific pure gas application. If straight oxygen samples are used with straight hydrogen fuel, the mixture entering the burner is essentially 100% H2 which tends to produce an unstable signal. The mixed fuel works better. Note that the choice of fuel determines certain analyzer characteristics as tabulated in Table A-2.

C.1 INSTRUCTIONS

This section provides a means of rapidly finding any desired function or configuration factor in the menu system.

The NGA menu system is necessarily complex due to the wide variety of configuration possibilities available with the NGA architecture.

This section consists of a series of titles describing the function or configuration desired, with a series of menu titles that show the path taken to that function.

The menu selections are sometimes abbreviated; Basic Controls is referred to as Basic for example, Expert controls and set up as Expert, and Technical level configuration as Technical.

CALCHKLIMITS if enabled forces the analyzer not to accept a calibration if the

calibration gas is more than CALFPC away from the target (as a percentage of the current fullscale range). If disabled it allows calibration no matter how far off the measurement is.

CALTIME sets the time over which the analyzer averages good measurement during the calibration cycle. This value should normally be left in the default setting.

PPENDIX

D. FID 2 M

ENU STRUCTURE

CALFAIL enables (or disables) the specific calibration failure alarm. If the analyzer determines that it cannot perform any of the possible calibrations, the calibration failure specific alarm will be set if CALFAIL is enabled.

CALFPC determines the allowable calibration error if CALCHKLIMITS is enabled. CALFPC is a percentage of the range on which the calibration is currently being

performed. It is normally left at 5%. CALTIMEOUT determines how long the analyzer will wait for a stable reading before

performing the calibration. Once this time has passed, the analyzer will calibrate anyway, though if the result is out of the CALFPC limits and CALCHKLIMITS is set, the calibration will not be accepted.

ZERORNGS determines whether the analyzer will attempt to zero all the ranges at once (see the discussion elsewhere on the po ssibility of this).

CALRANGES allows you to calibrate all the ranges at once, if the calibration gas is less than 110% of the fullscale value of each range.

Curve 2, 3, 4 menus are similar. The coefficients must add up to 1 to within 0.2% to achieve a 0.2% linearity. The A0 coefficient is the zero offset, and it should normally be set to zero. The upper limit shows the range over which the linearizer can work – and the over and under range percentages show the limit points.

Outside this range the transfer function will be a straight line whose slope is the gradient of the linearizer curve at the end point. This stops an inflected curve from playing havoc with the calibration algorithms.

Also, the curve must be uninflected! Any negative slope will make the calibration fail. The analyzer will detect this and fail to calibrate.

LONPVUPDATE

AMDELAYTIME

AFT90_ determines the filtering applied to each range. The time value is the time constant of the filter applied. This value also affects the degree of the median filter used.

The LONPVUPDATE variable controls how fast the analyzer puts the PVA signal (the main reading) onto the LON network. For normal operation this should be set to 10 samples per second, but for fastest performance set it to ASAP. If you have more than four analyzers on one network, setting all the analyzers to ASAP may overload the network, showing up as sluggish menu response. In this case, set them to 10 per second.

AMDELAYTIME determines the group delay of the PVA signal from this analyzer. It may be set between 0 and 30 seconds. Its effect is to delay the PVA from this analyzer by that amount, useful if you are trying to synchronize several analyzers that are measuring a common sample.

NITS MENU

Controls the units of these values as displayed on the control module screen and as reported by the DDE server when in "Native" mode. The actual variable contents are always in SI units.

The SI pressure unit is hPa (hecto-Pascals). These are supposed to be absolute pressures, but enough people find this confusing that we decided to report them as gauge pressures instead, using hPa as the "unit". Generally (except for barometric pressure readings) all NGA pressure readings are gauge.

Range settings are as described above. Linearization functions leads to a series of screens that support such self-linearization

capabilities as this analyzer has. As with most NGA analyzers, the polynomial selflinearization function is not enabled, while the mid-point correction is. The former menus are not described here. The midpoint correction allows you to set up to 3 mid points as well as the zero and span point for each range, such that the analyzer’s transfer function is a series of straight lines passing through these points. This correction is in addition to any polynomial linearization applied. This function may be used to force agreement with arbitrary mid-point gases whose values are accepted for regulatory reasons, despite any evidence to the contrary.
