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

/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.

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.
