PREFACE
INTENDED USE STATEMENT
This is a reference manual for the NGA series of analyzers. It contains in depth discussion of the various
features and operational elements of the analyzers, together with information about their use with com-
puters. It is not intended to be a stand-alone document, but should be combined with the individual ana-
lyzer and platform manuals.
A major part of this manual is the description of the NGA variables. These are the names of the packets of
information that are communicated over the NGA digital communication network, and are available for ex-
ternal access. It is vital that no attempt be made to directly affect their values without a complete under-
standing of the results of doing so. Serious damage to the analyzers may result from incorrect
assignments.
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
To avoid loss of life, personal injury and damage to this equipment and on-site property, all per-
sonnel authorized to install, operate and service this equipment should be thoroughly familiar with
and strictly follow the instructions in this manual. Save these instructions.
DANGER.
ELECTRICAL SHOCK HAZARD
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.
DANGER.
POSSIBLE EXPLOSION HAZARD
This equipment may contain modules used in the analysis of sample gases which may be flamma-
ble. If used for analysis of such gases, the module must be protected by a continuous dilution
purge system in accordance with Standard ANSI/NFPA 496-1993, Chapter 6.
WARNING.
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.
WARNING.
PARTS INTEGRITY
Tampering or unauthorized substitution of components may adversely affect safety of this product.
Use only factory documented components for repair.

GLOSSARY OF TERMS
AK
A European automotive protocol that runs on RS232 or RS485.
Analog I/O Module
A self contained computer that uses the Echelon Neuron chip as its processor. It gets data from the net-
work, and it performs the necessary calculations to produce the analog output and the relay indications.
Analyzer Module
The module that contains all sensor/detector components for development of a Primary Variable signal; in-
cludes all signal conditioning and temperature control circuitry.
Backplane
The interconnect circuit board which the Controller Board, Power Supply, Analyzer Module power and net-
work cables, I/O Modules and Expansion Modules plug into.
Bind
The process of connecting various variables in the analyzer module with equivalent variables in the I/O
modules
Calibrate
In ICEE monitoring, to zero, span and linearize an analyzer. In other industries, to zero and span an ana-
lyzer.
CLD
Chemiluminesense Detector Analyzer module
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.
DDE
Dynamic Data Exchange - a Microsoft Windows function that allows programs to talk to other programs.
DDE Server
Rosemount Analytical NGA2000 PC Interface Suite, consisting of software and hardware elements that al-
low communication between NGA2000 components and a personal computer (PC).
DIO
Digital Input/Output board, a special I/O Module that works with the Platform to provide many digital I/O
lines.

P-4 Preface Rosemount Analytical Inc. A Division of Emerson Process Management
NGA2000 Reference
Distribution Assembly
The Backplane and the card cages that hold I/O and Expansion Modules.
Echelon
Echelon Corporation.
Enumerated
An integer number whose value corresponds to a phrase. These are used to express one of several pos-
sibilities.
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.
Expert
Refers to the controls and configuration capability appropriate for engineering personnel.
Failure
A form of alarm: Failure indicates an unrecoverable hardware or software failure such as some component
not responding to network communications or a safety related failure such as lack of purge air in a FID
module.
FID
Flame Ionization Detector Analyzer module.
Floating point
A four byte IEEE floating point number (in Motorola format). This is a number that can take a very wide
range of values, but provides only about seven digits of precision. The analyzer main reading is expressed
as a floating point number. There can be up to 7 floating point variables in an array.
Health
Alarm status.
HFID
Heated Flame Ionization Detector Analyzer module.
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.
Inrush Current Limiting
To limit the current drawn by a piece of electronics when it is first switched on.
IIR
Infinite-Impulse-Response
