ELECTROSTATIC DISCHARGE
SAFETY SUMMARY
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 a ware of the following
considerations:
Best ESD example is when you w alked 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 adv antages of a modular
analyzer system. A TFID Analyz er Module (AM) as “blind” analysis unit it can be part of a multiple
NGA analyzer system or special customer-dev eloped control unit. TFID with front panel displa y/
operator interface is a stand-alone analyzer or central interface (control module) for multiple
analyzer modules.
The TFID is used in se veral areas of industry , safety of environment, research and de velop-ment.
T ypical applications are the LEL control, the emission and ambient air control or the e xhaust gas
PREFACE
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 displa y 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.

THEORY OF TECHNOLOGY AND OPERATION
MEASURING PRINCIPLE
2. Theory of 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.

THEORY OF TECHNOLOGY AND OPERATION
TFID MODE OF OPERATION
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 achiev ed by special transport of the sample gas and
the supply gases. Even big pressure de viations of the sample gas against atmosphere will ha ve
no significant influence to the signal. Two independent electronic differential pressure gauges
keep constant the differential pressure of the constant sample mass flo w to the flame by adding
separate air. The differential pressure system will alwa ys be kept on a constant pressure difference
against atmosphere. Thus, neither deviations of air pressure nor diff erences 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 shor t response times to deter mine the measured values. The compact
detector block is heated between 120 °C and 160 °C (up to 210 °C as option) being pre-selectiv e
to avoid condensation by b u rning and corrosion of the materials.

Rosemount Analytical
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 or ifice is placed
keeping the sample mass flow to the b urner 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 v ery small dead
times are requested, the sucked sample gas can be increased to appro x. 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.

GAS CONDITIONING (SAMPLE HANDLING)
PREPARATION
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 v erified 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.

Rosemount Analytical
The equipment has an internal power supply and is specified f or an operating voltage of 230 Vac
or 115 Vac resp., 50-60 Hz.
For supply of e xternal 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 s witching 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 hav e been previously switched on, in the system.
Y ou will find the “Single menu displa y” and raw values on the display and as secondary value
the message „WarmUp“. If the other secondary values show “Failures”, “MaintenanceRequests” 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 tak es about 45 minutes,
depending on the installed detectors and themostatic control !

SWITCHING ON
❍ 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 f or 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.

Automatic Internal Calibration
❏ Operation will switch from “W armUp” 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 eff ect will vanish after a certain operation time.
Notes:
3
You have to use nitrogen as zero gas for ranges <20 mg/m
in the environment air is more than 10 mg/m
The span gas rate alwa ys has to be greater than the sample gas rate to a void dilution eff ects 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 hydrocarbons.

21.4.1 Wiring with external actors
To connect external actors, observe following rules.
Problems for s witching off inductive loads:
Switching off an inductive consumer (relay, solenoid valve , etc.) can generate high voltage (up to
sev eral 100 V olt) at the connections of the coil. This voltage impuls circulates via connected lines
and could impair the function of near by equipments. Additional the outputs of DIO PCB could
be become wrecked.

PIN ASSIGNMENTS
Solution of problem:
Parallel connection of a silicium diode to the connections of inductiv e loading can short circuit this
voltage impuls to itself. This prevents circulation of voltage impuls via connected lines.
The diode should have following features:
Blocking voltage > 50 V
Forew ard current > 1 A
Diode type 1N4000 (e.g.) fits this requirements.
Connect cathode of diode to postive connection of consumer (see Fig. 21-7). Connect anode of
diode to negative connection of consumer.
