PREFACE
The purpose of this manual is to provide information concerning the components,
functions, installation and maintenance of the NGA2000 FID2 and the System Accessories
of the NGA 2000 System.
Some sections may describe equipment not used in your configuration. The user should
become thoroughly familiar with the operation of this module before operating it. Read
this instruction manual completely.
DEFINITIONS
The following definitions apply to DANGERS, WARNINGS, CAUTIONS and NOTES found throughout
this publication.
DANGER .
Highlights the presence of a hazard which will cause severe personal injury, death, or substantial
property damage if the warning is ignored.
WARNING .
Highlights an operation or maintenance procedure, practice, condition, statement, etc. If not
strictly observed, could result in injury, death, or long-term health hazards of personnel.
CAUTION.
Highlights an operation or maintenance procedure, practice, condition, statement, etc. If not
strictly observed, could result in damage to or destruction of equipment, or loss of effectiveness.
NOTE
Highlights an essential operating procedure,
condition or statement.

SAFETY SUMMARY
If this equipment is used in a manner not specified in these instructions, protective systems may be
impaired.
AUTHORIZED PERSONNEL
To avoid explosion, loss of life, personal injury and damage to this equipment and on-site property,
all personnel authorized to install, operate and service the this equipment should be thoroughly
familiar with and strictly follow the instructions in this manual. SAVE THESE INSTRUCTIONS.
DANGER.
ELECTRICAL SHOCK HAZARD
Do not operate without doors and covers secure. Servicing requires access to live parts which can
cause death or serious injury. Refer servicing to qualified personnel. For safety and proper per-
formance this instrument must be connected to a properly grounded three-wire source of power.
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 effec-
tive, 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 cir-
culation such as to dilute a worst case fuel or sample leak below 25% of the LEL. Doing so will ne-
gate 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 or unauthorized substitution of components may adversely affect safety of this product.
Use only factory documented components for repair.
WARNING.
HAND INJURY HAZARD
Do not place hands or fingers in the Platform front handles when front panel is open. Dropping the
front panel of the Platform while hand or fingers are inside either handle can cause serious injury.
WARNING.
POSSIBLE EXPLOSION HAZARD
Ensure that all gas connections are made as labeled and are leak free. Improper gas connections
could result in explosion or death.
WARNING.
POSSIBLE EXPLOSION HAZARD
Protection against explosion depends upon a special fuel flow restrictor in the fuel inlet fitting. DO
NOT REMOVE THE FUEL INLET RESTRICTOR. Use the correct fuel flow restrictor for the fuel being
used. Do not use 100% hydrogen fuel in a 40% H
2
/60% H
e
configured FID module. Replace with
factory supplied fitting only.
CAUTION .
PRESSURIZED GAS
This module requires periodic use of pressurized gas. See General Precautions for Handling and
Storing High Pressure Gas Cylinders, page P-5.
CAUTION .
OVERBALANCE HAZARD
This analyzer module may tip instrument over if it is pulled out too far and the Platform is not prop-
erly supported.

P-4 Preface Rosemount Analytical Inc. A Division of Emerson Process Management
Model NGA2000 FID2
CAUTION.
CONTROLLED ENVIRONMENT
This equipment is for use in a controlled environment. Refer to Section 1-6 Specifications (page 1-
7) in this manual for environmental conditions.
CAUTION.
HOT OVEN COMPONENTS
The oven and sample manifold are controlled to 80°C. Allow the analyzer to cool down before
touching any of these components.
CAUTION.
OVER-VOLTAGE SPIKING
If this analyzer module is used with a non-Rosemount Analytical power supply, adding Rosemount
Analytical PN 903341 Current Protector in series with the 24V positive power line will prevent over-
voltage spiking and resultant fuse blowing when powering up the instrument.
CAUTION .
STATIC ELECTRICITY
Circuit boards in this instrument are static-sensitive. Take all static precautions when handling the
circuit boards
NOTE
This Analyzer Module is completely leak-tested at the factory for gas leakage. The user is responsi-
ble for testing for leakage at the inlet and outlet fittings on the rear panel (with a test procedure
chosen by the user). The user is also responsible for leak-testing periodically and if any internal
pneumatic components are adjusted or replaced. See leak test instructions in Section 2-6 on page
2-6.

GENERAL PRECAUTIONS FOR HANDLING AND STORING HIGH
PRESSURE GAS CYLINDERS
Edited from selected paragraphs of the Compressed Gas Association's "Handbook of Compressed
Gases" published in 1981
Compressed Gas Association
1235 Jefferson Davis Highway
Arlington, Virginia 22202
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 lo-
cated 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 suit-
able 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 at-
tached 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, precau-
tions must be taken to prevent striking an arc against the cylinder.

DESCRIPTION AND SPECIFICATIONS
1-1 OVERVIEW
This manual describes the Flame Ionization
Detector (FID2) Analyzer Module of
Rosemount Analytical's NGA 2000 Series of
gas analysis components.
The FID2 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 FID2 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 FID2 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 (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.
The gas pressures are continuously
monitored and controlled through electronic
pressure transducers.
The measurement of concentration is placed
on the network, where it can be shown on the
Platform Display or on other data acquisition
devices.
