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
continuous dilution purge system is factory-installed (in accordance with
Standard ANSI/NFPA 496-1993, Chapter 6, and it must be functional at all times
during operation. DO NOT DISABLE THIS PURGE SYSTEM.

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.

CAUTION: PRESSURIZED GAS

This module requires calibration with a known standard gas. See General
Precautions for Handling and Storing High Pressure Gas Cylinders at the rear of
this manual.

CAUTION: HAND INJURY HAZARD

Dropping the front panel of the Platform while hand or fingers are inside either
case handle can cause serious injury.

CAUTION: PURGE AIR REQUIREMENT

This Analyzer Module must be used in conjunction with a device (Platform or PC
Interface) that can actively monitor network variables related to pressure or flow
of the continuous dilution purge, or the front panel LEDs of the Analyzer
Module, as installed, must be visible. The purpose of this requirement is to
maintain adherence to ANSI/NFPA 496 standard which assures the continued
viability of the purge system. Under no circumstances should any pressure or
flow indicator be connected to the PURGE AIR OUT outlet of the Analyzer
Module because this may affect the sealing performance of the module.

CAUTION: OVER-VOLTAGE SPIKING

If this Analyzer Module is used with a non-Rosemount Analytical power supply,
adding Rosemount P/N 903341 Current Protector in series with the 24 V positive
power line will prevent over-voltage spiking and resultant fuse blowing when
powering up the instrument.

Note
This Analyzer Module is completely leak-tested at the factory for gas leakage.

1.1 OVERVIEW

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

The FID Analyzer Module is designed to continuously determine the concentration of
hydrocarbons in a flowing gaseous mixture. The concentration is expressed in
parts-per-million or percent of volume.

The entire FID Analyzer Module is designed as a slide-in module (if configured in
stand-alone instrument fashion), removable from the front of the Platform, with gas
connections made from the rear. All electronics relative to sample detection and
conditioning are included in this module.

1.2 TYPICAL APPLICATIONS

The monitoring of atmospheric air for low-level hydrocarbon contaminants and
determining the hydrocarbon content of exhaust emissions from internal combustion
engines are examples of typical applications for the FID Analyzer Module.

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 sample
gas 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. This measure of concentration is placed on the network, where it is can be
shown on the Platform Display or on other data acquisition devices.

OP VIEW

1.4 GAS SAFETY FEATURES

The FID Analyzer Module is designed with a factory installed continuous dilution purge
system in accordance with standard ANSI/NFPA 496 - 1993, Chapter 6. Front-panel
LEDs indicate that the burner flame is lit and that the purge system is enabled. In
addition, fuel gas is automatically shut off when a flame-out condition occurs or the
safety system is disabled.

The purge system is enabled only if there is proper purge gas flow in, purge gas
pressure, and internal case pressure, and after five times the case volume has been
exchanged.

All tubing ahead of the burner is rigid metallic 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 through the combination of an
inlet fuel flow restrictor and purge gas flow.

NTRODUCTION

I

This module is designed to use 100% hydrogen fuel or 40% H

2

/60% He fuel at a
maximum inlet pressure of 3446 hPa-gauge (50 psig). A different flow restrictor is
used for each fuel type.

A standard FID Analyzer Module is only equipped to analyze a non-flammable
sample, below 100% of the LEL.

WARNING: POSSIBLE EXPLOSION HAZARD

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

1.5 FUEL GAS OPTION

The standard FID 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 f or determining
fuel gas type:

1. 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. 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 a constant cylinder
temperature.)

748331-E Rosemount Analytical November 1998

NGA 2000 Flame Ionization Detection Module

1-3

NTRODUCTION

I

2. 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.

An effective way to reduce the effect of internal oxygen is to dilute it with an inert gas.
This can be accomplished with a constant dilution of sample and calibration gases
upstream from 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 quality 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.

Typical flow rates with premixed fuel:

Fuel 100 cc/min
Sample 7 cc/min
Air 400 cc/min

Note that with a 40/60 premixed fuel, the above flow rates 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%) inert/sample and 300 cc (80%) air noted
earlier for straight hydrogen fuel.

Since sample flow in the case of mixed fuel operation is only about 1/6 of that with
straight hydrogen fuel, higher sensitivity is obtained with the latter. However, in any
application where the sample contains more than one species of hydrogen and/or a
varying concentration of oxygen, mixed fuel is preferred.

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 40% H2/60% O2, which tends to produce an unstable signal. The mixed
fuel works better. Note that the choice of fuel determines certain analyzer
characteristics, as shown in Table 1-1.

2.1 UNPACKING

If the FID Analyzer Module is received as a separate unit, 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

If the Analyzer Module requires assembly with other components (e.g., the Platform
and associated I/O Modules), do so at this time. Following the guides on the bottom
left and bottom center of the Platform, carefully slide the Analyzer Module halfway into
place.

CAUTION: HAND INJURY HAZARD

Do not place hands or fingers in Platform front handles when the front panel is
open. Dropping front panel while hand or fingers are inside either handle can

Lift the spring loaded pins on the front of the module, and carefully slide it the rest of
the distance. Secure the module in position by releasing the pins, which seat in the
available holes in the bottom of the case (see Figure 2-1). If the module and Platform
are difficult to assemble, remove the module, ensure the top cover of the module is
firmly seated on the hold down screws, and repeat the assembly procedure.

Connect the network cable to either the NETW ORK 1 or NETWORK 2 connection on
the Analyzer Module (see Figure 2-4), and the NETWORK connection on the
Backplane (see Platform manual). Connect the power cable to both the Analyzer
Module front panel and to the Backplane.

Install I/O Module(s) according to guidelines in the I/O manual. After startup and
calibration have been performed, secure the Front Panel with the six screws provided.

2.3 LOCATION

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.

2-2

November 1998 Rosemount Analytical 748331-ENGA 2000 Flame Ionization Detection Module

The cylinders of fuel, air, and calibration gas(es) and the source of purge air should be
located in an area of relatively constant ambient temperature.

2.4 GASES

NSTALLATION

I

2.4.1 O

VERVIEW

During normal operation, the Analyzer Module requires fuel and air to maintain the
burner flame as well as suitable standard gases for calibration and instrument air for
purge requirements. Criteria for selection of these gases follow in section 2.4.3.

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 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
absorbed hydrocarbons, such as temperature or pressure.

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. 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, hydrocarbon
free, two stage regulator and a shutoff valve.

All new external gas tubing (except for PURGE IN/OUT and SAMPLE BYPASS) is strongly
recommended, preferably pre-cleaned, stain-less 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.
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.

Purge air and burner air should be supplied from separate sources.

It is recommended that no connection be made to the PURGE AIR OUT port. If,
however, the analyzer's location requires interconnection with a venting system, the
3/8" O.D. line should be kept as short as possible, and no longer than four feet.

CAUTION: POSSIBLE INSTRUMENT DAMA GE

No connection should be made to the PRESSURE RELIEF VALVE fitting. Doing
so may cause damage to the instrument.

2.4.3 S

PECIFICATIONS

UEL GAS

F

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 fuel restrictor is marked with a red dot, and the sample capillary is marked with a

red or green dot for mixed fuel applications.
Some applications require the use of 100% hydrogen fuel. When using this option,

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

2-5

NSTALLATION

I

Note
The fuel restrictor and sample capillary are marked with a white dot for 100%

hydrogen fuel applications.

URNER AIR

B

In order to ensure a low background signal, burner air should contain less than 1 ppm
maximum total hydrocarbon content. An alternate 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.

URGE AIR

P

Instrument quality air, nitrogen, or other nonflammable gas is required for the saf ety
purge system.

ALIBRATION GASES

C

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.

ERO GAS

Z

- Analysis is affected by the background gas of the sample. Therefore, it is

recommended to use zero gas with as close to the background composition of the
sample as possible. Normally less than 0.5 THC as CH4 is sufficient.

If the burner fuel is 100% hydrogen, the zero gas, background gas of the sample or
background gas of the span gas cannot be hydrogen or oxygen. These gases
combined with pure hydrogen fuel would generate excessive heat in the burner,
causing deterioration of the internal components of the burner.

PAN GAS

S

- Span gas consists of a specified concentration of methane or other

hydrocarbon in a background gas such as nitrogen. Analysis is affected by the
background gas of the sample. Therefore, span gas containing the same background
gas as the sample is recommended. Then, the background effect is canceled out.

AMPLE GAS

S

- Sample gas should be nonflammable (below 100% of the sample's

LEL). For high sensitivity applications requiring background gas compensation,
contact the factory.

LOW RATE

F

- The sample flow rate must be between 0.5 L/min. and 2 L/min. Flow rate

for purge air should be 16 to 18 L/min.

RESSURIZATION/FILTRATION

P

the range of 483 to 1035 hPa-gauge (7 to 15 psig), and internally, should be 345

hPa-gauge (5 psig) nominally. Burner fuel pressures should be: 1725 to 3450
hPa-gauge (25 to 50 psig) for cylinder regulator, 1518 to 1723 hPa-gauge (22 to
25 psig) internal. Burner air pressures should be: 1725 to 3450 hPa-gauge (25 to 50
psig) for cylinder regulator, 965 to 1103 hPa-gauge (14 to 16 psig) internal. Purge air
(external supply) pressure should be between 689 and 1378 hPa-gauge (10 and
20 psig), 689 to 827 hPa-gauge (10 to 12 psig) nominal. The internal purge air
regulator pressure is factory preset at a nominal setting of 551 hPa-gauge (8 psig)
with a supply pressure of 689 hPa-gauge (10 psig). Noncompliance with these
specifications, particularly those concerning purge air, could cause over-pressure
damage to the module. The nominal internal case pressure is about 0.5 to 1.0 inch of
water, and the pressure relief valve is set at 1/3 psig (nominal).

At the very least, the module's safety system, which requires a certain volume of
purge air flowing through the case before allowing burner ignition, will not allow the
instrument to operate.

All internal pressure settings are preset at the factory, but the operator should check
for accuracy. Sample should be filtered for particulates down to two microns.

2.4.4 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

Two electrical connections are required on the Analyzer Module: POWER and
NETWORK. See Figure 2-4. On the Analyzer Module, two NETWORK connectors are
available, either of which is appropriate for: 1) interconnection with the Backplane of
the Platform or 2) "daisy-chaining" with other NGA 2000 components. Connect
Analyzer Module POWER to Backplane POWER or external 24 VDC power source.

3.6 STARTUP PROCEDURE

Apply power to the FID Analyzer Module. If it is associated with a Platform, do this by
plugging in the Platform to a power source. The Platform has no ON/OFF power
button. Once power has been supplied to the Platform, the FID Analyzer Module will
be energized.

30

2064

If the user's system contains only one Analyzer Module, all system components, the
Controller Board and the network "self-install" (bind together) during initial startup. If
the system contains more than one Analyzer Module, the startup sequence will
interrogate the network to locate and identify all components on the network. The user
will have to bind appropriate combinations of components after the startup sequence
(see section 3.7).

After the warm-up period (about one hour for the FID Analyzer module), all modules
are completely functional.

Before introducing gases to the FID, the user should check the general health of the
analyzer module's electronics by reviewing the results of its self test sequence. These
test results can be found by selecting the following from the Main Menu: Technical
Level Configuration, Diagnostic Menus, Analyzer Module Diagnostics, Self Test. All
tested parameters should indicate "Pass."

Descriptions of the tests performed follow:

• EEPROM test - Checks the EEPROM on the Analysis Computer PCB.

• EPROM test - Checks the EPROM on the Analysis Computer PCB.

• RAM test - Checks the RAM on the Analysis Computer PCB.

• Power supply test - Verifies that all internal DC voltages are within the

required tolerances.

• Network test - Checks the internal network interface.

• 20 bit ADC test - Checks the 20-bit ADC on the Analysis Computer PCB by

sending a DC signal through the Preamp PCB and reading the signal back with
the 20-bit ADC.

• 12 bit ADC test - Checks the 12-bit ADC on the Analysis Computer PCB by
sending a DC signal and reading the signal back with the 12-bit ADC.

• Power Supply PCB test - Checks the presence of the Power Supply PCB by
activating the 3-way air solenoid.

• Safety PCB test - Checks the presence of the Safety PCB by sending a
command and reading it back.

• Case temperature test - Compares the temperature read between the Preamp
temperature sensor and the case temperature sensor. They must be within
10°C of each other. This test sometimes fails if the case is opened. The sensor
in the Preamp will take longer to cool off since it is in an enclosure. Re-running
the self-test after thermal equilibrium will produce a positive result if the sensors
are working properly.

The self-test can be repeated at any time by activating the TEST softkey in the Self
Test Results menu.

Set the Range Number (Expert Controls sub-menu) to the desired setting (see Figure
3-12). Introduce all gases at suitable pressures (see Specifications page in the
Preface section of this manual).

TARTUP AND OPERATION

S

Purge air of the following specifications must be present:

Flow: 16 to 18 L/min.
Supply Pressure: 689 to 1378 hPa-gauge (10 to 20 psig).

Noncompliance could cause damage to the module. At the very least, the module's
safety system, which requires a certain volume of purge air flowing through the case
before allowing burner ignition, will not allow the instrument to operate. The lowest
purge air flow/pressure setting possible during burner operation is preferable. Thus,
the user should set the external purge air pressure initially at 689 hPa-gauge (10 psig).
Check the Miscellaneous Control Parameters screen under Technical Diagnostics,
and note whether the Purge Gas (switch) variable is "ON." If it is "OFF," increase
purge air supply by 69 hPa-gauge (1 psig), and recheck the Purge Gas variable until it
reads "ON." DO NOT EXCEED 1378 hPa-GAUGE (20 PSIG). If the maximum setting
is reached, and the Purge Gas variable does not read "ON," contact factory. If the
safety system is initiated successfully (Purge Gas variable is "ON"), continue with the
remainder of the startup procedure.

Note
Do not restrict the PURGE OUT port and the pressure relief valve. They must be

vented to atmospheric pressure.

Two methods of burner ignition are possible: auto-ignition and manual ignition. Note
the four LEDs on the front panel of the Analyzer Module. They provide necessary
information for either ignition procedure. The LEDs, when illuminated, denote the following
information:

Green - unit powered on
Amber - constant illumination indicates case temp. is within 5% of operating

temp. setpoint (i.e., 50°C with burner off, 54°C with burner

on);otherwise, LED will blink
Green - Flame on
Green - purge air system intact (it has filled five volumes of the module

interior)

Auto-ignition provides fuel override and three attempted ignitions (default setting), if
necessary. Manual ignition requires that the Platform front panel, if used, be
disengaged.

CAUTION: HAND INJURY HAZARD

Do not place hands or fingers in Platform front handles when the front panel is
open. Dropping front panel while hand or fingers are inside either handle can
cause serious injury.

3-8

TARTUP AND OPERATION

S

The manual ignition switch on the Analyzer Module front panel must be manipulated in
the following ways:

• Press up and hold for one minute. This opens burner fuel and air solenoids.

• Press down to ignite burner glow plug for up to 10 seconds.

• Repeat as necessary (if fuel and air sources are farther away than 10 feet,

several more attempts may be necessary).

• Flame on is defined true when the flame temperature exceeds 115°C (239°F).

• If the flame has been lit, but the flame temperature increases slowly, perform

the following steps:

# After igniting flame, release switch for 2 sec.
# Press switch down for 2 sec.
# Repeat release switch and press down steps as necessary.

3.7 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 Figures 3-11 through 3-15 and
section 1.5 of the I/O Modules manual for binding instructions.)

3.8 CALIBRATION

See section 2.3.3 for a description of the method for choosing calibration zero and
span gases.

To calibrate the Analyzer Module, introduce zero gas into the SAMPLE INLET, and do
the following:

1. If more than one Analyzer Module is functional and the split Run Mode display is
shown, press the DISPLAY softkey until the desired Analyzer's Run Mode display
is acquired.

2. Press the MENUS softkey to enter the Main Menu.

3. Verify the fuel type in the Miscellaneous Control Parameters menu (under the
Technical Configuration menu structure, select the following from the Main Menu:
Diagnostic menus, Analyzer Module Diagnostics and then Miscellaneous Control
Parameters).

4. Verify the capillary type in the Analyzer Manufacturing Data menu (under the
Technical Configuration menu structure, select the following from the Main Menu:
Technical Level Configuration, Service Menus, Manufacturing Data, Analyzer
Module Data).

5. In the Calibration Gas List menu (from the Main Menu, select Expert Controls and

748331-E Rosemount Analytical November 1998

NGA 2000 Flame Ionization Detection Module

3-9

TARTUP AND OPERATION

S

Setup, Analyzer Module Setup, then Calibration Gas List), enter necessary data,
including the Operational Sample Pressure and the Calibration Gas HC Response
Factor. Common HC factors are: methane (CH4), 1.0, ethane (C2H6), 1.90,
propane (C3H8), 3.00. These factors are not used to compensate the reading, but
are used to select the proper preamp sense resistor.

6. Press HOME to re-enter the Main Menu, enter the Basic Controls menu, introduce
zero gas and allow its response to stabilize, press the ZERO softkey to enter the
Analyzer Zero menu, press ZERO ag ain and w ait.

7. Press the SPAN softkey to enter the Analyzer Span menu, introduce span gas and
allow its response to stabilize, press SPAN again and wait.

8. Press the HOME softkey to re-enter the Main Menu.

9. Press DISPLAY softkey for the Run Mode display.

If the user is unable to calibrate the Analyzer Module (i.e., when ZERO or SPAN is
initiated, nothing happens), several possible solutions present themselves. 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) will 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 this 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 this
section, ensuring that case temperature and displayed measurement reading are
stable before initiating the calibration routine.

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

3.9 ROUTINE OPERATION

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

so that flow discharged from the BYPASS outlet is between 0.5 and 2.0 L/min. The
reading on the SAMPLE BYPASS pressure gauge should be the same as that used
during adjustment of the span control. Adjust, if necessary.

Adjust the Range Number setting. The Analyzer Module will now automatically and
continuously output the measured hydrocarbon content of the sample. Output is in

3-10

November 1998 Rosemount Analytical 748331-ENGA 2000 Flame Ionization Detection Module

TARTUP AND OPERATION

S

terms of the particular hydrocarbon present in the span gas. Note that readings
obtained during operation depend on the concentration of total hydrocarbons in the
sample.

If maximum sensitivity is required from the FID Analyzer Module, use an optimum
combination of settings on the SAMPLE, FUEL, and AIR pressure regulators. Settings
must be determined experimentally, but the curves in Figures 3-7, 3-8 and 3-9 may be
used as guides.

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 Module Data. Select Maximum
Range, and use the arrow keys to scroll the indicated value. The same applies for
Minimum Range settings.

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; see Figure 3-11). 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.

3.10 SAFETY SYSTEM

The FID Analyzer Module safety system will not allow ignition or continuous burner
function unless the following conditions are present:

• Internal purge gas pressure is at least 380 hPa-gauge (5.5 psig). (Monitor
display message, Purge Gas Pressure in Physical Measurements menu, for the
proper setting.)

• Internal fuel pressure is less than 2064 hPa-gauge (30 psig). (Monitor display
messages, Fuel Supply Pressure in Physical Measurements menu and Fuel
Pressure Status "ON" in Miscellaneous Control Parameters menu for proper
settings. If the internal fuel pressure has exceeded 2064 hPa-gauge [30 psig],
check that the external pressure is less than 3450 hPa-gauge [50 psig]. The
+24 VDC power to the Analyzer Module must be cycled to continue operation.)

• Flow rate for purge air in is at least 16 L/min. and case pressure is greater than

0.5 inch of water. (Monitor display message, Purge Gas "ON" in Miscellaneous
Control Parameters menu for correct state. Proper sealing hardware must be
used in order to obtain the required purge air in flow rate and case pressure.)

• Five case volumes of purge air have been achieved and the three above
conditions are present. The time duration to achieve a safe system is a

748331-E Rosemount Analytical November 1998

TARTUP AND OPERATION

S

minimum of 6 min. The elapsed time can be monitored in the Technical Startup
Analyzer menu. (Monitor the Purge Air Green LED "ON," Purge Control Status
"ON," or Purge Air Alarm for indication of the state of the safety system.)

As stated above, proper sealing hardware is crucial to the successful operation of the
safety system. Therefore, a specific torquing sequence (as shown in Figure 3-10)
must be followed when the front panel of the module is being reinstalled after removal.
All front and rear panel screws must be installed.

Note
Do not over-torque rear panel screws.

Torque Sequence:

Screw #1, 4 to 5 turns
Screw #2, 4 to 5 turns
Screw #3, 4 to 5 turns
Screw #4, 4 to 5 turns
Screw #5, 4 to 5 turns
Screw #6, 4 to 5 turns

CAUTION: QUALIFIED PERSONNEL

This equipment should not be adjusted or repaired by anyone except properly
qualified service personnel.

4.1 BURNER DISASSEMBLY AND CLEANING

Disassemble the burner only if contaminants must be removed. Combustion products
or other contaminants which accumulate inside the burner may form electrical leakage
paths between the collector and the burner contact, resulting in noisy readings.

If the instrument is to be operated at the highest sensitivity, traces of such
contaminants can cause erroneous readings. For best performance, clean the burner
per the following procedure:

ISASSEMBLY

D

1. Power OFF the module.

2. Shut fuel gas, air and sample gases OFF.

3. Slide Analyzer Module from the Platform (if applicable).

CAUTION: HAND INJURY HAZARD

Do not place hands or fingers in Platform front handles when the front panel is
open. Dropping the panel while hand or fingers are inside either handle can
cause serious injury.

4. On the combustion chamber, disconnect the polarizing voltage cable and amplifier
input cable.

5. Disconnect the four connectors attached to the burner (one to glow plug, two to
preamp board , and one to thermistor).

748331-E Rosemount Analytical November 1998

NGA 2000 Flame Ionization Detection Module

NGA 2000 F

LAME IONIZATION DETECTION MODULE

6. Disconnect the four gas supply
tubes (two air, one fuel and one
sample).

7. Disconnect the exhaust tube.

8. Remove the burner assembly by
loosening the two securing nuts.

9. Unscrew the burner cap retainer
ring, and remove burner cap.

10. Loosen clamp; lifting straight up,
remove combustion chamber­chimney assembly from the
manifold.

Note
If the old burner tip assembly is to

be used again, do not touch it with
bare hands or any materials likely
to contaminate it with
hydrocarbons, salt, etc.
Additionally, all items used for
cleaning (tweezers, swabs, etc.)
must be absolutely free of
contamination.

3. Replace burner cap (and flameout sensor assembly), with flameout sensor
assembly in-line with burner exhaust.

4. Install burner onto module base.

5. Connect all leads and tubing. Replace module cover and install module into
Platform.

Note
Fittings using Teflon pipe seal tape:
Replace Teflon pipe seal tape to maintain a tightly sealed burner assembly.

4.2 COMPONENT REPLACEMENT

Components which may require replacement include; sample capillary, fan, fuses,
EPROM, printed circuit boards and front panel LED's.

Replacement of each of these components require sliding out the bottom chassis from
the enclosure.

Three fuses that may be replaced are located on; 1) the Network/Power Assembly, 2)
the Safety Board and 3) the Power Supply Board. If the thermal fuse on the Safety
Board or the Power Supply Board require replacement, this indicates a overheating
condition, which denotes a wider problem requiring troubleshooting.

EPROM's should only be replaced by qualified electronics personnel because special
tools and knowledge are required.

For accessibility when replacing printed circuit boards, the printed circuit board
mounting panel has been designed to swing down.

4.3 BURNER STARTUP TROUBLESHOOTING

If unable to startup burner, check the following:

1. All supply gas cylinder pressures are within specifications (see Specifications in
Preface section).

2. Correct gases are being supplied to each back panel inlet.

3. Air, not zero gas (if nitrogen), is being supplied to burner.

4. Burner exhaust is being vented to atmospheric pressure, and is not tied to either
purge air exhaust or another FID exhaust.

5. Burner exhaust continuously slopes downward until reaching atmospheric pressure
vent.

6. Parameters "IS/WAS" match in the Physical Measurement Parameters screen
(see Figure 3-13); use NEXT softkey to view all parameters.

AINTENANCE AN D TROUBLESHOOTING

7. As a last resort, check burner fittings for leaks (purge air pressure is higher than
the pressure in any of the lines connected to the burner; thus, any leak would be

the fitting rather than

into

out

of it).

Used by Permission

1. Never drop cylinders or permit them to strike each other violently.

2. Cylinders may be stored in the open, but in such cases, should be protected against
extremes of weather and, to prevent rusting, from the dampness of the ground. Cylinders
should be stored in the shade when located in areas where extreme temperatures are
prevalent.

3. The valve protection cap should be left on each cylinder until it has been secured
against a wall or bench, or placed in a cylinder stand, and is ready to be used.

4. Avoid dragging, rolling, or sliding cylinders, even for a short distance; they should be
moved by using a suitable hand-truck.

5. Never tamper with safety devices in valves or cylinders.

6. Do not store full and empty cylinders together. Serious suckback can occur when an
empty cylinder is attached to a pressurized system.

7. No part of cylinder should be subjected to a temperature higher than 125°F (52°C). A
flame should never be permitted to come in contact with any part of a compressed gas
cylinder.

8. Do not place cylinders where they may become part of an electric circuit. When electric
arc welding, precautions must be taken to prevent striking an arc against the cylinder.
