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 per­formance 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 effec­tive, 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 circu-
lation such as to dilute a worst case fuel or sample leak below 25% of the LEL. Doing so will negate 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.

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 located 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 suitable 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 attached to a pressurized system.
7. No part of cylinder should be subjected to a temperature higher than 125 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, precautions must be taken to prevent striking an arc against the cylinder.

QUICK STARTUP PROCEDURE

Instruction Manual
748412-E
March 2003
The purpose of this reference guide is to pro­vide a easy to follow, step-by-step procedure through initial start-up an ignition of the FID2 Analyzer Module. This procedure assumes that the customer has already made all nec­essary electrical and gas connections and es­tablished the proper network connections.
1. Turn on power to the instrument. The #1 LED (POWER) will illuminate. The #3 LED (BLOCK) will begin flashing.
2. If sample gas has been connected and the sample pressure to the analyzer is sufficient to provide and accurate read­ing, the #4 LED (SAMPLE) will be illu­minated.
3. Allow the analyzer module to warm-up and the burner block temperature to reach the proper minimum ignition tem­perature (50°C). When the burner block temperature reaches the mini­mum ignition temperature, the #5 LED (IGNITE OK) will come on.
4. The instrument is now ready to be lit. Lighting the burner can be conducted in one of two methods: a) manual ignition from the front panel of the Analyzer Module or b) auto-ignite from the Plat­form.
a. To light the instrument from the
Analyzer Module, hold the “FUEL OVERRIDE/IGNITE” switch (located to the left of the indicator lights) in the up (FUEL OVERRIDE) position for 30 seconds. Immediately move the switch to the down (IGNITE) po­sition. The “IGNITE” mode is auto­matically set to stay on for a preset time period and does not require the switch to be held down. If the light­ing procedure was successful, the #2 LED (FLAME) will begin flashing as the flame temperature rises to the correct operating temperature. Once the LED becomes solidly lit, the flame has reached operating temperature.
b. To light the instrument from the Plat-
form using the auto-ignite mode, simply press the “light” softkey shown in the “Light Flame” menu of the Platform. The Analyzer Module will begin to go through an auto­mated sequence of enrichment and ignition similar to the manual mode described in step 5. If the burner fails to light the first try, the Analyzer Module will perform 2 more tries be­fore terminating the auto-ignite se­quence. If the Analyzer Module fails to light after 3 attempts, an error message will be displayed showing the cause of the fault.
5. If the burner fails to light, check all gas connections for proper gas composition and pressure, block temperature, and outlets for obstructions. Repeat step 4.
6. If the flame is lit, the #2 LED will begin flashing. Once the flame temperature has reached the correct operating tem­perature, the LED will remain on solid.
7. If the fuel and air pressures and ratios are within proper operating parameters to support a continuous flame opera­tion, the #6 LED (FUEL/AIR) will illumi­nate. This light will not be on before or during flame ignition.
8. Once the burner block temperature reaches the control temperature of 80°C, the #3 LED will stay on solid.
9. If the instrument has be successfully lit, the temperatures are up to proper op­erating levels, and the fuel, air, and sample gases are properly adjusted to support the flame and achieve reliable results, all 6 indicator lights will be lit solid.
The instrument is now ready for calibration or burner optimization.

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.

1-4 GAS SAFETY FEATURES

The FID2 module is divided into two parts - a pneumatic section and an electronic section. The two sections are separated by a pair of solid partitions to prevent any leak of gas in the pneumatic section from reaching the elec­tronics. The electrical connections into the pneumatic section are made intrinsically safe by a series of over-voltage protection devices and current limiting resistors. The burner it­self is an explosion-proof assembly. The combination of these two techniques allows the analyzer to meet international safety stan­dards without the use of an expensive con­tinuous-dilution purge - but ONLY when it is installed in a general purpose area with good air circulation.
WARNING
POSSIBLE EXPLOSION HAZARD
Hydrocarbon concentration(s) in the sam­ple gas must be below the Lower Explo­sion Limit (LEL).
The FID2 is designed to use 40% H fuel at a maximum inlet pressure of 3446 hPa­gauge (50 psig).

WARNING
POSSIBLE EXPLOSION HAZARD
Protection against explosion depends upon a special fuel flow restrictor at the fuel inlet. DO NOT REMOVE THE FUEL INLET RESTRICTOR.

1-5 FUEL GAS OPTION

The standard FID2 Analyzer Module requires 40% hydrogen/60% helium burner fuel gas.
For monitoring internal combustion exhaust emissions or other sample gas with varying oxygen content, mixed fuel is preferable. In fact, a hydrogen/helium mixture is more desir­able than a hydrogen/nitrogen mixture. With this type of sample, the use of mixed fuel gas minimizes the error introduced by oxygen synergism.
/60% He
2
All tubing ahead of the burner is rigid metallic tubing assembled with ferrule/nut type com­pression fittings. However, should an internal fuel leak occur, a worst-case leak would be dissipated below 25% of the LEL of hydrogen by natural dilution outside of the pneumatic section before it could be ignited by any ex­ternal ignition source, and there is nothing within the pneumatic section to ignite it.
Changes in the burner air flow rate have little effect on signal strength. For a given flow, the signal can be optimized by adjusting the fuel flow rate.

INSTALLATION

2-1 UNPACKING

When the FID2 Analyzer Module is received, carefully examine the shipping carton and contents for signs of damage. Immediately no­tify the shipping carrier if the carton or con­tents is damaged. Retain the carton and packing material until all components associ­ated with the Analyzer Module are opera­tional.

2-2 ASSEMBLY

The FID2 analyzer module MUST NOT be placed within a conventional NGA platform, single module enclosure or dual module en­closure since the latter would not allow free flow of air around the module, thus violating its safety certification. The enclosure is de­signed so that this would be very hard to do anyway.
There is a special platform specifically de­signed to accept this module; consult the fac­tory for details.

2-3 LOCATION

WARNING.
POSSIBLE EXPLOSION HAZARD
Do not place the FID2 module within an­other enclosure unless the latter has a guaranteed air circulation such as to dilute a worst case fuel or sample leak below 25% of the LEL. Failure to will negate the safety features and may result in explo­sion, serious injury, material damage and death. Also, do not cover the vent holes on the top and sides of the module.
Install the Analyzer Module in a clean, weather-proofed, non-hazardous, vibration­free location free from extreme temperature variations. For best results, install the Ana­lyzer Module near the sample stream to mini­mize sample transport time.
Operating ambient temperature is 5 °C to 40 °C, limited to temperature changes of less than 10 °C/hr. Acceptable dew point range is less than 95% relative humidity, but not in ex­cess of 40°C wet bulb temperature.
The cylinders of fuel, air, and calibration gases should be located in an area of rela­tively constant ambient temperature.
CAUTION .
PRESSURIZED GAS

2-4 GASES

a. Overview

During normal operation, the Analyzer Module requires fuel and air to maintain the burner flame as well as suitable stan­dard gases for. Refer to the criteria for selection of these gases in Section 2-4c on page 2-2.
After initial startup or after startup follow­ing a prolonged shutdown, the analyzer may display baseline drift for a consider­able period of time, particularly on the most sensitive range.
Commonly, the drift is caused by small amounts of organics (such as hydrocar­bons) in the inner walls of the tubing in both the internal flow system and the ex­ternal gas supply system. Drift results from any factor influencing the equilibrium of these adsorbed hydrocarbons, such as temperature or pressure. Hydrocarbons adsorbed within the analyzer in the gas passageways (or in the fuel or air lines) will elevate the overall baseline.
Rosemount Analytical Inc. A Division of Emerson Process Management Installation 2-1
Instruction Manual
748412-E March 2003
Note that this type of drift occurs only when the flame is burning. If drift occurs when the flame is extinguished, the elec­tronic circuitry is at fault or the burner or cabling is contaminated with a conductive film. To minimize drift, use clean fuel and air, keep the analyzer clean, and locate the gas cylinders in an area of relatively constant ambient temperature.
The cylinders supplying all gases each should be equipped with a clean, hydro­carbon-free, two-stage regulator and a shutoff valve.
All new external gas tubing (except for SAMPLE BYPASS) is strongly recom­mended, preferably pre-cleaned, stainless steel, gas chromatograph-grade tubing. Thoroughly clean before use (if a hydro­carbon-based cleaning solvent such as acetone is used, purge tubing with dry ni­trogen or helium for several minutes be­fore using.)
Gas line connections are compression fit­tings. Do not use pipe thread tape on such fittings.
Since the oxidation of hydrogen is ac­companied by the formation of water va­por, the exhaust tubing always should be slanted downward at least 6 degrees from horizontal. Otherwise, water may accumu­late in the line, causing back pressure and noisy readings, or may back up in the line and flood the burner.
If the sample is toxic or noxious, or is to be reclaimed, connect the Bypass outlet to a suitable disposal system. Do not use any device that may cause back pressure in the line.
Model NGA2000 FID2
exhaust and bypass must be vented at atmospheric pressure to a non-classified location in accordance with ANSI/NFPA-
496.

c. Gas Specifications

Fuel Gas — Standard analysis usually
requires mixed fuel, i.e., 40% (±2 %) hy­drogen and 60% helium. H is recommended over H of better linearity in concentration output. Such blends are supplied by many gas vendors specifically for this use, with a guaranteed maximum total hydrocarbon content of 0.5 ppm, measured as meth­ane. This specification should be used when obtaining these mixtures.
Burner Air — In order to ensure a low
background signal, hydrocarbon free grade air with less than 1 ppm maximum total hydrocarbon content is highly rec­ommended. An alternative source for
burner air and zero gas (see Calibration Gases below) is a combination diaphragm
pump and heated palladium catalyst. This process continuously removes moderate amounts of hydrocarbons and carbon monoxide from ambient air.
Calibration Gases — Calibration method
and gases depends on the type of fuel gas used, the operating range, and the desired measurement accuracy. In all methods, zero and span gases are used, and are introduced through the sample inlet at the rear of the module.
Zero Gas It is recommended that the
gas should have a composition as close to the background composition of the sample as possible.

sample be filtered for particulates down to 0.1 microns. A suitable filter is
the Balston type 95S6 with 0.1 micron fil­ter element. It should normally be re­placed on a two week schedule, depending on the sample.
Pressure/Filtration — See Table 2-1 on
page 2-4 for input pressure specifications. Noncompliance with these specifications could cause over-pressure damage to the module.
Leak Test — The Analyzer Module is
completely 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. The user is also
responsible for internal leak testing peri­All internal pressure settings are preset at the factory, but the operator should check
for accuracy. It is essential that the
odically and if any internal pneumatic
components are adjusted or replaced
(with a test procedure chosen by the
user).

2-5 ELECTRICAL CONNECTIONS

NOTE
Electrical installation must be in compli­ance with National Electrical Code (NEC/NFPA 70) and/or any state or local codes.
Two electrical connections are required on the Analyzer Module: POWER and NETWORK. See Figure 2-3 below. On the Analyzer Mod­ule, two NETWORK connectors are available, either of which is appropriate for: 1) intercon­nection with the Back plane of the Platform or
2) "daisy-chaining" with other NGA 2000
components, or 3) connection to a PC via a suitable LONTALK adapter and software such as the NGA DDE server and client. Connect Analyzer Module POWER to Back plane POWER or external 24 VDC power source.
Connect the network cable to either the NETWORK 1 or NETWORK 2 connection on the Analyzer Module front panel, and the NETWORK connection on the LON I/O mod­ule if used with a Platform, or directly to a computer using appropriate LONTALK adapter hardware and software such as the NGA DDE server. Connect the power cable to both the Analyzer Module front panel and to a 24V 5A minimum power supply.

b. Manometer Method

The FID2 Analyzer Module is completely tested at the factory for gas leakage. The user is responsible for testing for leakage only at the inlet and outlet fittings on the rear panel.
CAUTION
SENSOR PRESSURE
Do not expose the sensor to pressure in excess of 1.0 psig as this may cause dam­age.

a. Flow Indicator Method

Supply air or inert gas such as nitrogen, at 1 psig (6.8 hPa), to the analyzer through a flow indicator with a range of 0 to 250 cc/min. Install a shut-off valve at the sample gas outlet. Set the flow rate to 125 cc/min.
FID2 Analyzer Module
Install a water-filled U-tube manometer at
the sample gas outlet. Install a shut-off
valve at the sample gas inlet. Admit air or
inert gas to the inlet shut-off valve until
the analyzer is pressurized to approxi-
mately 50 hPa. The water column will be
about 500 mm.

Figure 2-5. Leak Test - Manometer Method
Close the inlet shut-off valve and, follow-
ing a brief period for pressure equilibrium,
verify that the height of the water column
does not drop over a period of about 5
minutes. If the water column height drops,
the system is leaking and must be cor-
rected before the introduction of any
flammable sample gas or application of
power.

c. Troubleshooting Leaks

Liberally cover all fittings, seals, and other
possible sources of leakage with a suit-
able leak test liquid such as SNOOP (part
837801). Bubbling or foaming indicates
leakage. Checking for bubbles will locate
most leaks but could miss some, as some
areas are inaccessible to the application
of SNOOP. For positive assurance that
system is leak free, perform one of the
tests in Section 2-6 above.
