NGA 2000 Flame Ionization Detection Module
PURPOSE/SAFETY SUMMARY
The purpose of this manual is to provide information concerning the components,
functions, installation and maintenance of this particular NGA 2000 module.
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.
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 this
equipment should be thoroughly familiar with and strictly follow the instructions
in this manual. Save these instructions.
If this equipment is used in a manner not specified in these instructions,
protective systems may be impaired.
DANGER is used to indicate the presence of a hazard which will cause severe
personal injury, death, or substantial property damage if the warning is ignored.
WARNING is used to indicate the presence of a hazard which can cause severe
personal injury, death, or substantial property damage if the warning is ignored.
CAUTION is used to indicate the presence of a hazard which will or can cause minor
personal injury or property damage if the warning is ignored.
NOTE is used to indicate installation, operation or maintenance information which is
important but not hazard-related.
Operate this equipment only when covers are secured. Servicing requires
access to live parts which can cause death or serious injury. Refer servicing to
qualified personnel.
For safety and proper performance, this module must be connected to a
properly grounded three-wire source of electrical power.
WARNING: ELECTRICAL SHOCK HAZARD
PREFACE
P-2 November 1998 Rosemount Analytical 748331-ENGA 2000 Flame Ionization Detection Module
WARNING: POSSIBLE EXPLOSION HAZARD
WARNING: PARTS INTEGRITY
WARNING: FLAMMABLE SAMPLES
CAUTION: OVERBALANCE HAZARD
CAUTION: PRESSURIZED GAS
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.
Consult the factory if flammable samples will be measured.
Tampering with or unauthorized substitution of components may adversely
affect safety of this product. Use only factory-approved components for repair.
Ensure that all gas connections are made as labeled and are leak free. Improper
gas connections could result in explosion and death.
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.
This Analyzer Module may tip instrument over if it is pulled out too far and the
Platform is not properly supported.

NGA 2000 Flame Ionization Detection Module
CAUTION: HAND INJURY HAZARD
CAUTION: PURGE AIR REQUIREMENT
CAUTION: OVER-VOLTAGE SPIKING
Dropping the front panel of the Platform while hand or fingers are inside either
case handle can cause serious injury.
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.
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.
The user is responsible 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 2.4.4.

GLOSSARY
ANALYZER MODULE
The module that contains all sensor/detector components for development of a
Primary Variable signal; includes all signal conditioning and temperature control
circuitry.
BACKPLANE
The interconnect circuit board which the Controller Board, Power Supply, Analyzer
Module power and network cables, I/O Modules and Expansion Modules plug into.
CONTROL MODULE
The Operator Interface plus the Controller Board.
CONTROLLER BOARD
The computer board that serves as the Network Manager and operates the Display
and Keypad.
DISTRIBUTION ASSEMBLY
The Backplane and the card cages that hold I/O and Expansion Modules.
EXPANSION MODULE
A circuit board that plugs into the Backplane from the front of the Platform and
performs special features not related to I/O functions.
I/O MODULE
A circuit board that plugs into the Backplane from the rear of the Platform. Has a
connector terminal for communication with external data acquisition devices and
provides an input/output function.
OPERATOR INTERFACE
The Display and Keyboard.
PLATFORM
Any workable collection of the following: Controller Board, Power Supply, Distribution
Assembly, Enclosure and Operator Interface.
POWER SUPPLY
Any of a variety of components that provides conditioned power to other NGA 2000
components, from the Power Supply Board that plugs into the front of the Backplane
in a stand-alone instrument to several larger ones that can power larger collections of
modules and components.
