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.

PREFACE

748331-E Rosemount Analytical November 1998 P-3

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.
