ELECTROSTATIC DISCHARGE
CAUTION
ELECTROSTATIC DISCHARGE
The electronic parts of the Analyzer Module can be irreparably damaged if exposed to
electrostatic discharge (ESD).
The instrument is ESD protected when the covers have been secured and safety precautions observed. When the housing is open, the internal components are not ESD
Although the electronic parts are reasonable safe to handle, you should be aware of the following considerations:
Best ESD example is when you walked across a carpet and then touched an electrical grounded metal
doorknob. The tiny spark which has jumped is the result of electrostatic discharge (ESD).
You prevent ESD by doing the following:
Remove the charge from your body before opening the housing and maintain during work with opened housing, that no electrostatic charge can be built up.
Ideally you are opening the housing and working at an ESD - protecting workstation. Here you can wear a wrist
trap.
However, if you do not have such a workstation, be sure to do the following procedure exactly:
Discharge the electric charge from your body. Do this by touching a device that is grounded electrically (any
device that has a three - prong plug is grounded electrically when it is plugged into a power receptacle).
This should be done several times during the operation with opened housing (especially after leaving the
service site because the movement on a low conducting floors or in the air might cause additional ESDs).

ANALYZER SYSTEM ARCHITECTURE
The NGA 2000 HFID is available as a "stand-alone analyzer" or as a "blind" Analyzer Module (AM). The HFID
analyzer module can be part of the stand-alone analyzer or a component of an analyzers system (Fig. A-1).
The NGA 2000 system made it possible, to configure
the HFID as a flexible "stand-alone analyzer" consisting
of a HFID "Analyzer Module", a Platform (complete with
front panel display/operator interface), and input/output
(I/O) modules.
The “analyzer module” is a “blind” analysis unit but retains all the advanced design features. The AM variant
is designed for integration as part of a NGA 2000 analysis system or special customer developed networks.
The platform/MLT´s front panel can act as operator interface for a stand-alone analyzer or as the a central
interface for multiple Analyzer Modules. In multi analyzer systems, this feature eliminates duplication of the
display/operator interface. In addition to the obvious operational benefits there are significant cost and system
packaging advantages not possible with conventional
analyser configurations.
This flexible network communication architecture is
shown in the schematic of Fig. A-2.

1-1OVERVIEW
NGA 2000 HFID
SECTION 1
DESCRIPTION AND SPECIFICATIONS
This manual describes the Heated Flame Ionization Detector (HFID) Analyzer Module of Emerson Process
Mangement´s NGA 2000 Series of gas analysis components (See Figure 1-2 and 1-3).
The HFID Analyzer Module is designed to continously
determine the concentration of hydrocarbons in a flowing gaseous mixture at a user-selectable temperature
setpoint between 93 °C and 204 °C (200 °F and 400 °F).
The concentration is expressed in parts-per-million or
percent of volume..
The HFID 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.
1-2TYPICAL APPLICATIONS
The monitoring of carbon bed scrubber for low-level hydrocarbon contaminants, determining of the hydrocarbon content of exhaust emissions from internal combustion engines and continuous emissions monitoring of fluegas emissions (e.g. incinerators) are examples of typical
applications for the HFID Analyzer Module
1-3SAFETY GAS FEATURES
The HFID Analyzer Module is designed with a factoryinstalled continous dilution purge system in accordance
with standard ANSI/NFPA 496-1993, Chapter 6. Frontpanel 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 of
the safety system is disabled.
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.
This module is designed to use 40% H2/60% He fuel at a
maximum inlet pressure of 3446 hPa-gauge (50 psig).
A standard HFID 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.
Replace only with factory applied fitting.
Do not use 100 % hydrogen fuel in a 40 % H2 /
60 % He configured Analyzer Module.
An explosion resulting in severe personal injury
or death could occur.
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.

1-4THEORY OF TECHNOLOGY
Instruction Manual
HAS64E-IM-HW
September 2008
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.
With a 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.
+ 90 V
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 aquisition devices.

2-3LOCATION
Instruction Manual
HAS64E-IM-HW
September 2008
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.
WARNING
INSTALLATION RESTRICTIONS
For safety, the Analyzer Module should be installed
in a non-confined, ventilated space. Do not block
any of the rear panel outlets as they are part of the
safety system.
Operating ambient temperature is 15 °C to 35 °C (59 °F
to 95 °F), limited to temperature changes of less than
10 K/hr. Acceptable dew point range is less than 95 %
relative humidity, but not in excess of 45 °C (113 °F) wet
bulb temperature.
The cylinders of fuel, air, and calibration gas(es) and the
source of purge and regulated air should be located in
an area of relatively constant ambient temperature.
2-4GASES
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 minimze 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 precleaned, 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.
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. Depending on the
percent of vapor in the sample, the sample bypass out
connection may be required.
a.Overview
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. In addition, instrument air for regulated air in is required to control the sample pressure at
the sample capillary. Criteria for selection of these gases
follow in Section 2-4c.
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.
2 - 2InstallationEmerson Process Management GmbH & Co.OHG
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.

BURNER EXHAUST is a 3/8-inch connection.
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 DAMAGE
No connection should be made to the PRESSURE

c.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 fuel restrictor is marked with a red dot, and
the sample capillary is marked with a red or green
dot for mixed fuel applications.
Burner Air
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.
Purge Air
Calibration Gases
Calibration method and gases depend on the operating
range, and the desired measurement accurancy. In all
methods, zero and span gases are used, and are introduced through the sample inlet at the rear of the module.
ZERO GAS - 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 CH
is sufficient.
SPAN GAS - Span gas consists of a specified concentra-
tion of methane or other hydrocarbon in a background
gas such as nitrogen.
NOTE
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.
Sample Gas
Sample gas should be nonflammable (below 100 % of
the sample´s LEL). For high sensitivity applications requiring background gas compensation, contact the factory.

Pressure / Filtration
SAMPLE PRESSUREat the SAMPLE inlet should be within
the range 345 to 620 hPa-gauge (5 to 9 psig nominal),
and internally, should be between 206.7 and 275.6 hPagauge (3.0 and 4.0 psig).
BURNER FUEL PRESSURE should be:
3101 to 3450 hPa-gauge (45 to 50 psig) for cylinder regulator, 1723 hPa-gauge (25 psig) nominal for internal pressure.
BURNER AIR PRESSURE should be:
1725 to 3450 hPa-gauge (25 to 50 psig) for cylinder regulator, 1035 hPa-gauge (15 psig) nominal for internal pressure.
REGULATED AIR PRESSURE should be:
689 to 1725 hPa-gauge (10 to 25 psig) for cylinder regulator.
PURGE AIR PRESSURE should be:
689 to 1380 hPa-gauge (10 to 20 psig).
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).
2-5LEAK TEST
The Analyzer Module is completely tested at the factory
for gas leakage (leakage rate - 7.5 hPa/min. (- 0.11 psig/
min.) with He or - 2.5 hPa/min. (- 0.036 psig/min.) with
N2). The user is responsible for leakage testing at the
inlet and outlet fittings on the rear panel minimum twice
a year (see Section 4-13).
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).
CAUTION
OVER PRESSURE DAMAGE
Noncompliance with these specifications,
particulary tose concerning purge air, could cause
over-pressure damage to the module.

SECTION 3
OPERATION
3-1OVERVIEW
Once the HFID has been correctly assembled and installed, the analyzer module is ready for operation.
Before operating the system, verify that the Leak Checks
have been performed in accordance with Section 2-5.
In this section, all operations for starting up the analyzer
are explained. For more detailed information about software screens see associated Software Manual.
For the remainder of this section, Analyzer Module interconnection with a Platform or some interfacing component is assumed. Display and Keypad information
refers to that which the user can expect to see and do
with regard to the Front Panel of the Platform.
Depending from the software version that is installed,
menu layout can change, whereas the principle of operation always stays the same.
3-2STARTUP & INITIALIZATION
CAUTION
PRESSURIZED ENCLOSURE
This enclosure shall not be opened unless the area
is known to be free of flammable materials or unless all devices within have been de-energized.
Area classification for the protected enclosure:
Nonclassified.
Pressurization: Type Z
Temperature Identification Number: T4A
Power shall not be restored after enclosure has
been opened (or loss of purge) until enclosure has
been purged for a minimum of 6 (six) minutes at
the minimum pressure of 689 hPa (10 psig).
For safety, the Analyzer Module should be installed
in a non-confined, ventilated space. Do not block
any of the rear panel outlets as they are part of the
safety system.
a)Startup
1.Connect supply gases and outlets to/from module.
2.Turn ON the purge gas only. Wait a minimum of 6
minutes (see Section 3-2b, too)
3.Apply LON connection and power to the HFID 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 HFID
Analyzer Module will be energized.
After switching on the HFID, the analyzer will begin its booting procedure which is apparent on the
screen. The first part of the initialization procedure
is a self check of the software and analyzer components. Various displays will show the status of
the initialization.

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 the Platform
manual for instructions on binding combinations
of modules.
Pressing the F1 key during initializing will reset
the HFID brightness and contrast to factory settings. Pressing the F3 softkey will abort the network initializing, aborting any connection to other
analyzers. In that case, only the menus of the local analyzer will be available.
At the end of the initializing routine the "measure"
screen will display. This screen is the access to all
other channels, menus and submenus. The actual display may differ from that shown depending on any custom configuration.
After the warm-up period (about one hour for the
HFID Analyzer Module), all modules are completely functional.

•Case temperature test - Compares the tempera-
ture read between 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.
•Oven/Sample Temperature test - Compares the
temperature read between the sample temperature sensor and the oven temperature sensor.
They must be within 50°C of each other.
5.Wait for the Purge Air green LED to illuminate.
b)Temperature/Pressure Settings and Check
1.Introduce the remaining supply gases. (See section 1-5 Specifications)
2.Set and verify the internal gas pressures.
Check pressure settings with the values defined
in your Test Data Sheet (Figure 3-12).

Supply Pressure: 689 to 1,378 hPa-gauge
(10 to 20 psig)
This, the user should set the external purge air
pressure initially at 689 hPa-gauge (10 psig).
Check the "Miscellaneous Control Parameters"
screen (Figure 3-2), 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.

Noncompliance could case 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.

c)Ignition of the Flame
1.Manual or Auto-Ignite the flame. The Flame-On
green LED should be illuminated.
Two methods of burner ignition are possible:
auto-ignition and manual ignition
(Note: The burner is easier to ignite when the oven
has reached the desired setpoint temperature.)
Auto-Ignition of the Flame
Auto-ignition provides fuel override and three attempted ignitions (default setting), if necessary.
Before ignition and operation, Fuel Flow must be
set on "ON" in "Light Flame" display screen under
Basic Controls (Figure 3-7) and oven temperature must be at least 85°C.
Manual Ignition of the Flame
The manual iginition 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).
•If the flame has been lit, but the flame tem-
perature increases slowly, perform the following steps:
1) After igniting flame, release switch for 2
seconds
2) Press switch down for 2 seconds
3) Repeat release switch and press down
steps as necessary.
4.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 . continous illumination implies oven has
reached operating temp. within ± 6 °C of
setpoint.
•Green - flame on
•Green - purge air system intact (it has filled
five volumes of the module interior)
5.Check and re-adjust the internal pressures if
required.
The unit is ready for operation.
3-3BINDING
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.
2.Allow the case and oven to warm up approximately
1 to 2 hours.
3.Verify that all 4 LEDs are illuminated.

3-4CALIBRATION PROCEDURE
The HFID analyzer module may require periodic calibration with known zero and span gases in order to maintain a desire level of analytical accurancy. It is recommended, after initial startup, that the HFID Analyzer Module is calibrated at least once every eight hours.
This practice should continue until evidence indicates
that some other interval is more appropriate depending
on the analytical accurancy required.
Calibration is the process of flowing known zero or span
calibration gas into the analyzer for a specified period
(averaging time), after which the analyzer will automatically set its zero or span factors so that the concentration measurement equals the calibration gas value. A
limit can be set, beyond which any attempt by the analyzer to reset its concentration measurement will cause
a warning alarm. In this case, user intervention would
be required to reset the alarm and attempt another calibration.

Zero (Span) ranges:
Used to select wether to calibrate ranges "TOGETHER"
or "SEPARATELY". If together, zeroing or spanning will
go through each range one by one. If the change required is too great, it will fail and send an alarm if warning alarms are enabled. In this case, Disable Calibration Adjustment Limits and try again. First check that the
calibration gases are correct. If non-zero gases are used,
or the changes are great, zero and span may have to
be repeated a few times.
In case that a system calibration is used, set all ranges
to "SEPARATELY".
Please note that Software will accept only span gas values that are a factor of 10-110% of the measuring range.
From that, it is possible, that not all of the four measuring ranges can be calibrated altogether. In that case
you will have to set the option to "SEPARATELY".
In case that a calibration is not possible because the
difference of display to the true value is too great, switch
of the "CalCheck" option.
Set the time used by the analyzer to average its reading
during calibration. A longer time will give a better calibration.
When using a system calibration, take care that averaging time is long enough for the analyzer to reach a
settled reading. Otherwise, calibration may fail !
Calibration failure alarm:
When turned on ("yes"), issues a warning if the analyzer has to change its calibration by more than the Cal
Failure Error, if warning alarms are enabled.
Cal failure error allowed:
The percentage by which the calibration can change
before an alarm is triggered if the Calibration Failure
Alarm is enabled.
Calibration time out:
Sets how long the analyzer will wait for the signal to
stabilize before issuing a Warning.

c)Problems with Calibration
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 the correct zero and span calibration gases
are being used properly. If so, attempt to recalibrate
according to instructions at the beginning of Section 3-4, ensuring that the oven, sample and case
1
temperatures 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.
Push the softkey F4 again to start the spanning sequence. Be sure to have span gas flowing through your
analyzer and to have it purged before.
When the spanning sequence is finished, the "Calibration status" will turn to "READY".
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.
3.Recalibrate the analyzer module according to instructions at the beginning of section 3-4, ensuring that oven, sample, and case temperatures and
displayed measurement reading are stable before
initiating the calibration routine.
4.Enable Calibration Adjustment Limits in the Calibration Parameters menu (Figure 3-5).
NOTE
If the range selections straddle 72 5ppm, CH4, the
zero and span calibration for each range must be
done separately.

3-5ROUTINE OPERATION
a)Operation
After case, oven, and sample temperature stabilization,
calibration, and binding, proceed as follows:
Supply heated sample gas to SAMPLE INLET. Adjust
external flow controller or throttle valve so that the sample
inlet pressure is between 345 to 620 hPa-gauge (5 to 9
psig.), 485 hPa-gauge (7 psig.) nominal. The reading
on the SAMPLE pressure gauge and sample and oven
temperatures should be the same as that used during
adjustment of the zero and span calibration gas control.
Adjust the Range Number setting. The Analyzer Module will now automatically and continously output the
measured hydrocarbon content of the sample. Output
is in terms of particular hydrocarbon present in the span
gas. Note that readings obtained during operation depend on the concentration of total hydrocarbons in the
sample.
The Analyzer Module will not allow the user to increase
the upper limit of a range beyond the "maximum range"
software setting.
To now check back physical parameters of the HFID
Analyzer Module with the values defined in your Test
Data Sheet, that you received with the analyzer, you
have to select the "Physical Measurements"-Menu.
You will find excerpt of a Test Data Sheeta as an example on the next page in figure 3-12.

After starting up the Analyzer Module, the Measure Mode
Display is displayed as shown in figure 3-10.
After initial startup, or startup following a prolonged shutdown, the Analyzer Module requires about one day´s
continous operation to stabilize. For several days afterwards, calibrate daily. The frequency of subsequent
calibrations can be reduced as experience dictates,
consistent with the accurancy requirements of the particular application.
HOMEESCAPEINFO
Figure 3-11: Physical Measurements Display
The menu "Physical Measurements" lets you monitor
physical measurement parameters of the HFID analyzer.
b)Sensitivity
If maximum sensitivity is required from the HFID Analyzer Module, use an optimum combination of settings
on the FUEL, and AIR pressure regulators. Settings must
be determined experimentally, but the curves in Figures
3-14 and 3-15 may be used as guides.
c)Shutdown
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" on the Light
Flame menu (under Basic Controls, Figure 3-7). Subsequently, remember to set Ignition System Enable to
"On" before attempting to ignite the flame.

3-6 SAFETY SYSTEM
The HFID Analyzer Module safety system will not allow
ignition or continous burner function unless the following conditions are present:
•The internal purge gas pressure is at least 380
hPa-gauge (5.5 psig).
Monitor message "Purge Gas Pressure" in "Physical Measurements" menu (Figure 3-11) for proper
setting.
•Flow rate for purge air in is at least 16 l/min and
case pressure is greater than 0.5 inches of water.
(Monitor display message "Purge Gas (ON)" in
"Miscellaneous Control Paramteres" menu (Figure 3-2) 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 minimum of 6 min. (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 torque sequence (shown in
Figure 3-13) 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.

4-13 LEAKAGE TEST
The gas path system should be leak tested at least twice
a year and after maintenance, replacement or repair of
gas path parts.
a)Required Tools
•Test Medium
•external Manometer
•Swagelok® Blind Unions SS (2)
•Swagelok® Blind Unions brass (2)
•tube piece with rubber stopper
b)Procedure
To perform a leakage testing, proceed as follows (see
figure 4-23):
1.Close gas supplies and disconnect the gas connections
2.Close „Fuel IN“, „Burner Air IN“, „Bypass OUT“
and „Regulated Air IN“ with blind unions
3.Close „Exhaust“ with a tube piece with rubber stopper.
4.Connect a pressure meter to „Sample IN“ fitting
5.Connect test medium supply (N2 or He) to the pressure meter
6.Supply Analyzer Module with the test medium with
a pressure of max. 250 hPa (3.63 psig) and close
supply. Since HFID internal it comes to equalization of pressure, supply is to open and to close
repeatedly until manometer doesn’t show pressure changes.
CAUTION
POSSIBLE INSTRUMENT DAMAGE
The pressure of the test medium must
not exceed 250 hPa (3.63 psig) !
7.Watch the manometer.
Over a period of about 5 minutes the pressure
drop may not be higher than 7.5 hPa/min. (- 0.11
psig/min.) using Helium (He) or 2.5 hPa/min.
(- 0.036 psig/min.) using Nitrogen (N2).
If the specifications (see table 4-1) were adhered to,
then the test is finished.
