5.1 Electrostatic Discharge

The electronic parts of the analyzer can be irreparably damaged if exposed to electrostatic

discharge (ESD).

The instrument is ESD protected when the covers have been secured and safety precautions

observed. When the housing is open, the internal components are not ESD protected anymore.

Although the electronic parts are reasonable safe to handle, you should be aware of the following

considerations:

Best ESD example is when you walked across a carpet and then touched an electrical grounded

metal doorknob. The tiny spark which has jumped is the result of electrostatic discharge (ESD).

You prevent ESD by doing the following:

Remove the charge from your body before opening the housing and maintain during work with

opened housing, that no electrostatic charge can be built up.

Ideally you are opening the housing and working at an ESD - protecting workstation.

Here you can wear a wrist trap.

However, if you do not have such a workstation, be sure to do the following procedure exactly:

Discharge the electric charge from your body. Do this by touching a device that is grounded

electrically (any device that has a three - prong plug is grounded electrically when it is plugged into

a power receptacle).

This should be done several times during the operation with opened housing (especially after

leaving the service site because the movement on a low conducting floors or in the air might cause

additional ESDs).

Preface

The Thermo-FID (TFID) as member of the NGA 2000 familiy has all the advantages of a modular

analyzer system. A TFID Analyzer Module (AM) as “blind” analysis unit it can be part of a multiple

NGA analyzer system or special customer-developed control unit. TFID with front panel display/

operator interface is a stand-alone analyzer or central interface (control module) for multiple

analyzer modules.

The TFID is used in several areas of industry, safety of environment, research and develop-ment.

Typical applications are the LEL control, the emission and ambient air control or the exhaust gas

analysis in the chemistry and combustion engine development. But you can also use the TFID to

optimize a process or to control any limits at operating position.

A lot of auxiliary functions are available by the micro electronic of the TFID. The integrated CPU

allows the operation via menu, the automatic self control and error diagnostics. The display shows

all instruction notes and auxiliary reports in plain language. The very small currents of the FID

detector are always evaluated in the optimum range by the processor controlled dynamic amplifier.

The amplified signals will be digitalized directly at the detector and sent out to the CPU. So, a

falsification of the small detector signal will become impossible and the high resistant screened

cable will become unnecessary.

1. Technical Description

All components of analyzer or analyzer module are incorporated into a 1/1 19" housing.The housing is available as rack mounting (R) or as table-top (T) versions. For analyzer modulesthere is mounted a blind plate instead of an operation front panel.

The Flame Ionization Detector (FID) is designed to continuously determine concentrations ofhydrocarbons.

The TFID offers the following Advantages:a) The instrument is designed modular according to function groups resulting in:

Easy troubleshooting Fast error removal High availability

b) The analyzer is sucking automatically sample gas via a pump system being installed behindthe detector.

c) The sample gas is sucked direct into the detector without using a superposed sample gaspump. Therefrom: No heated sample gas pump No additional heating of sample gas inlet (or heated bypass as option) No “cold” connections leading to condensation; in that way avoiding corrosion and

THEORY OF TECHNOLOGY AND OPERATION

Rosemount AnalyticalMEASURING PRINCIPLE

2. Theory o f Technology and Operation

2.1 Measuring Principle

The Flame Ionization Detector measuring principle is based on ionization of hydrocarbons in a

hydrogen flame (or hydrogen/ helium mixture ).

Since a pure hydrogen flame creates only a very small basic ionization the burning of

hydrocarbons in ppm range results in ionization currents being decades higher than pure

hydrogen.

Thus a constant sample gas stream and a constant hydrogen or H2/He stream are mixed and fed

to the detector over a burner nozzle being put on a negative potential (approx. - 80 Vdc to

- 400 Vdc). In the burner chamber of the detector the mixture is burned by adding hydrocarbon

free air in relation of approx. 10 : 1.

The resulting ions are collected on a polarized electrode, amplified and put to display.

MEASURING PRINCIPLE


2 - 390003806(1) NGA-TFID e 22.06.98


2.2 TFID Mode of Operation

The burning of organic substances in a hydrogen flame will produce electrical charged particles

(ions). A negative acceleration voltage at the burner nozzle will discharge these ions to the

electrode of the current amplifier. The high sensitive amplifier will evaluate the current of this

process. The intensity of this current depends on the concentration of the carbon atoms in the

sample gas. Therefore it is possible to determine the measured value of the organic carbon

(organic C) directly.

A flame is produced in a heated burner chamber by burning pure hydrogen and added clean air.

Besides a part of the sample gas will be fed to the flame. A constant sample mass flow is absolutely

necessary to determine accurate and precise the concentration of the organic carbon. It is also

necessary that deviations of the sample gas pressure may not change the pressure proportions

in the burner chamber and the sample mass flow to the flame.

A constant mass flow over a long period is achieved by special transport of the sample gas and

the supply gases. Even big pressure deviations of the sample gas against atmosphere will have

no significant influence to the signal. Two independent electronic differential pressure gauges

keep constant the differential pressure of the constant sample mass flow to the flame by adding

separate air. The differential pressure system will always be kept on a constant pressure difference

against atmosphere. Thus, neither deviations of air pressure nor differences in altitudes will have

any influence to the measured values.

Instead of a conventional heated sample gas pump a heated air jet injector is inserted each behind

the burning chamber resp. behind the flame arrestor. As option it is also possible, that an unheated

diaphragm pump is used instead of the heated air jet injectors.

The suction pump can be placed either on the rear side of TFID or external.

The sample gas has no direct contact with the used control fittings. Even the electronic sample

gas flow control happens without a flow meter and without direct contact with the sample gas.

Because of this construction the Thermo-FID has a very small dead volume. As consequence the

Thermo-FID has very short response times to determine the measured values. The compact

detector block is heated between 120 °C and 160 °C (up to 210 °C as option) being pre-selective

to avoid condensation by burning and corrosion of the materials.

TFID MODE OF OPERATION


2 - 4 90003806(1) NGA-TFID e 22.06.98

Rosemount AnalyticalSAMPLE GAS TRANSPORT

2.3 Sample Gas Transport

The sample gas transport through the detector is realized by two independent pumps as standard.

2 heated air jet injectors and as option one unheated diaphragm pump sucking before or behind

the burner chambers are used.

The pumps create before and behind the burner chamber an underpressure being kept constant

via 2 independent differential pressure gauges to different pressures.

Between the differential pressure gauges and before the burner chamber an orifice is placed

keeping the sample mass flow to the burner nozzle constant.

Using this principle of sample gas transport a heated pump is not necessary.

Pressure deviations of about -300 mbar to + 600 mbar against atmosphere do not have any

significant influence on the result. With a optional sucking pump -200 mbar to + 600 mbar against

atmosphere is possible. This means very low response times and no additional heating of the

sample inlet.

The volume of the sucked sample gas is about 10 to 25 l/h (25 l/h as standard). If very small dead

times are requested, the sucked sample gas can be increased to approx. 80 - 100 l/h as option.

At detector sample gas inlet a flame trap is located which has detector temperature.

Behind the heated flame trap working also as sample gas filter an electronic flow control is placed

being not in direct contact with the sample gas. This is avoiding contamination.

All materials being in contact with sample gas are heated to 120 - 210 °C (pre-selective) and high

corrosion resistant.

The analyzer/module must not operate in explosive atmosphere without

supplementary protective measures !

Free flow of air into and out of the TFID (ventilation slits) must not be

hindered by nearby objects or walls !

For rack installation be sure, that the TFID has space on top and on bottom of

min. 1/2 HU to avoid overheating !

The installation site for the TFID has to be dry and remain above freezing

point at all times. The TFID must be exposed neither to direct sunlight nor

to strong sources of heat.

Be sure to observe the permissible ambient temperatures (c.f. Item 20: Technical

Data). For outdoor installation, we recommend to install the TFID in a protective

cabinet. At least, the TFID has to be protected against rain (e.g., shelter).

For Installation site please take care about safe way to reach the analyzer.

The equipment has to be installed as near as possible to the sample point , in order to avoid

low response time caused by long sample gas lines.

5.2 Gas Conditioning (Sample Handling)

The conditioning of the sample gas is of greatest importance for the successful operation of any

analyzer according to extractive method.

All gases have to be supplied to the TFID as conditionned gases !

When the instrument is used with corrosive gases, it is to be verified that there

are no gas components which may damage the gas path components.

The gas has to fulfill the following conditions:

It must be

free of condensable constituents being not compatible with detector temperature

free of dust

free of aggressive constituents which are not compatible with the material of the gas

paths.

have temperatures and pressures which are within the specifications stated in “Technical

Data” of this manual.

Inflammable or explosive gas mixtures may not be introduced into the TFID

without supplementary protective measures !

When analysing vapours, the dewpoint of the sample gas has to be at least 10 °C below the

detector temperature in order to avoid the precipitation of condensate in the gas paths.

Suitable gas conditionning hardware may be supplied or recommended for specific analytical

problems and operating conditions.

The equipment has an internal power supply and is specified for an operating voltage of 230 Vac

or 115 Vac resp., 50-60 Hz.

For supply of external components (external heater) there is built in a 230 Vac or 115 Vac outlet

plug (female, max. 4 A). For temperature control of the external heater there are terminal strips

to connect the thermo element of the external heater (Pt 100) to the TFID (Fig. 6-1).

Be sure, that all gas supply valves are closed !.

Connect network to other analyzers / modules (see Fig. 6-1).

Connect mains line and internal power supply (see Fig. 6-1, Plug POWER).

Verify before operation whether the line voltage stated on the label of the

TFID agrees with that of your mains line!

Optional connect external heater to voltage supply and Pt-100 to terminal strips (Fig. 6-1).

Switchin On the TFID via mains switch (Fig. 6-1, switch to its "I" position).

For analyzers only:

The analyzer must be switched on only after switching on all modules connected

to the network.

Upon switching on, the TFID will perform a self-diagnostic test routine.

After switching on, the software integrates automatically all the individual modules, which are

incorporated in the TFID via network and have been previously switched on, in the system.

You will find the “Single menu display” and raw values on the display and as secondary value

the message „WarmUp“. If the other secondary values show “Failures”, “Maintenance-

Requests” and “Function-Control” you can see “YES” for each of them.

For further informations about the displays while switching on look at the respective software

manual.

Warming-up after switching on takes about 45 minutes,

depending on the installed detectors and themostatic control !

SWITCHING ON

6 - 390003806(1) NGA-TFID e 16.06.98


Put in the span gas concentration (Vol.-% or ppm) of the span gas certificate, the number

of carbon atoms, the name of the span gas and the response factor (see Item 20.5) !

The correctness of these values is very important for the automatic calibration !

(The standard concentration of the span gas is approx. 500 ppm propane in nitrogen.)

Now, you can start the pneumatic operations:

Open the supply gas valves and set up the supply gas pressure values !

The calculator will start with the automatic startup procedure after the catalyst and the

detector have reached the necessary temperature.

The following procedures will run automatically:

Test of the temperatures

Test of the control sensors

Calibration of the differential pressures

If all inputs are working correct the startup procedure will continue automatically with:

Switch on of the sample gas system - pump will start automatically

Control of the fuel gas (hydrogen or H2/He) pressure

Set up of the fuel gas (hydrogen, H2/He) flow rate for the flame

After fuel gas, zero and span gas pressure are correct and warm-up is finished the

messages “Failure” and “Maintenance-Request” will disappear

Ignition of the flame

After a successful ignition of the flame the automatic internal calibration will start.

SWITCHING ON

6 - 4 90003806(1) NGA-TFID e 16.06.98


Automatic Internal Calibration

Operation will switch from “WarmUp” to “Calibration” and Function Control shows “YES”.

When the procedure is finished Operation shows “Ready” and Function Control “NO”.

The internal automatic Calibration procedure will be:

Purging with zero gas

After the purging time: Zero calibration.

Purging with span gas

After the purging time: Span calibration.

Purging free with zero gas

Switching to sample gas

The calculator will switch to the measurement cycle if the current calibration curve agrees with

the reference calibration curve of the initial calibration.

The first startup may contain some mistakes:

Maintenance request will be set if the deviation from the initial calibration curve is more than

entered value

The deviation from the initial calibration curve during the first startup of the system happens

normally only for small ranges. This effect will vanish after a certain operation time.

Notes:

You have to use nitrogen as zero gas for ranges <20 mg/m3 if the concentration of hydrocarbons

in the environment air is more than 10 mg/m3 and cannot be transformed catalytic to CO2.

The span gas rate always has to be greater than the sample gas rate to avoid dilution effects with

the air. Normally, you can achieve it with a span gas pressure of 3 bar abs.

A suitable span gas is propane in nitrogen or in synthetical air. The span gas concentration should

be 60 to 80% of the required measurement range. It can be necessary to calculate “response factors”

because the measurement signal of a flame ionization detection may differ for different hydrocar-

bons.

Before start of measurement we recommend entry of the desired TFID parameters and to zero

and span the TFID.

21.4.1 Wiring with external actors

To connect external actors, observe following rules.

Problems f or switc hing off inductive loads:

Switching off an inductive consumer (relay, solenoid valve, etc.) can generate high voltage (up toseveral 100 Volt) at the connections of the coil. This voltage impuls circulates via connected linesand could impair the function of near by equipments. Additional the outputs of DIO PCB couldbe become wrecked.

Solution of pr oblem:

Parallel connection of a silicium diode to the connections of inductive loading can short circuit thisvoltage impuls to itself. This prevents circulation of voltage impuls via connected lines.

The diode should have following features:Blocking voltage > 50 VForeward current > 1 ADiode type 1N4000 (e.g.) fits this requirements.

Connect cathode of diode to postive connection of consumer (see Fig. 21-7). Connect anode ofdiode to negative connection of consumer.
