2.1 Scope of application

The FIDAMAT 6 gas analyzer is used for the
quantitative determination of hydrocarbons. The
analyzer is also suitable for measurements in
corrosive and condensing gas mixtures.

The measuring principle is based on flame
ionization detection (FID) with a minimum
detection level of about 0.1 ppm. During
combustion of hydrocarbons in a hydrogen flame,
ions are produced which are in turn converted into
a current flow by application of an electrical field.
The current intensity arising from this is a
measure of the number of carbon atoms.

Benefits

The FIDAMAT 6 gas analyzer stands out due to
its very wide scope of application.
Accordingly, measurement is possible:

2.3 Mode of operation

The FIDAMAT 6 measures compound-class-specifically not
component-specifically. It measures the total of all organic carbons in
a measuring gas but giving different weighting to the hydrocarbon
molecules.

As a first approximation, the value displayed is proportional to the
number of C atoms in the molecule in question. In practice, however,
there are deviations from this. The reading deviation for the molecule
in question is expressed by the response factor.

The measuring gas is supplied to the FIDAMAT 6 under overpressure
or drawn in by the built-in diaphragm pump (optionally via a heated
line and an additional filter) and then routed to the flame ionization
detector via a non-clogging fused-silica restrictor. Within the detector
the hydrocarbons contained in the measuring gas are combusted in
an oxy-hydrogen flame. During the combustion process the organic
hydrocarbons are ionized.

Technical description

The ions which are released are converted into an ion current by the
polarization voltage between two electrodes and then measured using
a highly sensitive amplifier.

The current measured is proportional to the number of organic C
atoms of the hydrocarbons in the measuring gas.

A pressure regulator keeps the pressure of the hydrogen constant. A
mutually adjusted system of pump, capillaries and combustion-air
pressure regulator ensures a constant measuring-gas pressure.

After switching on the analyzer, the flame will be ignited as soon as a
flame temperature of 165°C has been reached. The pump is started
automatically once the flame reaches a temperature of 220°C.

The FIDAMAT 6 sends out various signals in the form of floating
contacts:

• Maintenance request
Measuring-gas flow rate (filter / pump)
Fan failure (advance warning for measurement accuracy)
The unit continues to measure as normal and the measured value is
not affected.

• Fault
Hydrogen, combustion air and measuring gas pressure, temperature,
physical section and pump, fault in the electronics (temperature).
The measured value can be affected; under certain circumstances the
unit will switch into a different state (the combustion-gas valve is
closed). See also "List of maintenance requests” on page 6-5.

Note

Sample gases must be free of dust when they enter the analyzers.
Condensate should be avoided. For this reason, it will in most
application cases be necessary to use a gas conditioning device
suitable for the measurement task in question.

6, OXYMAT 6/ 61, CALOMAT 6, ULTRAMAT 23
and also FIDAMAT 6 provide the following
communication methods:

• ELAN interface (also with SIPROM GA)

• PROFIBUS DP / PA

• AK interface

ELAN interface

ELAN is a serial interface (RS 485) built in as
standard and which allows communication
between several analyzers. A maximum of 12
analyzers with no more than four components
may be networked together. Connection can be
made even without a PC.
The following diagram shows how this works.

PROFIBUS DP / PA

PROFIBUS DP / PA is the field-bus market leader.
All Siemens gas analyzers when equipped with an
optional plug-in board (can be retrofitted) have
Profibus capability and meet the mandatory "device
profile for analysis devices” defined by the PNO
(PROFIBUS Nutzer Organisation) (Profibus users
organization). Centralized access to the analyzers
installed in the system is possible using the
SIMATIC PDM operator control utility.

The term "field bus” designates a digital
communication system with which decentrally
installed field devices in a system are networked
together using a single cable and at the same
time connected to automation devices or to a
process control system.

Due to its high transmission speeds coupled with
relatively small data volumes for each device, the
PROFIBUS DP variant is used widely in
production automation, while PROFIBUS PA
takes particular account of properties demanded
in process control, such as large quantities of
data and deployment in explosion-hazard areas.

The benefits to the user lie is considerable
potential for savings in all parts of the system,
from engineering and commissioning, to
operation and maintenance, and later on to
installation expansion.

Technical description

FIDAMAT 6 gas analyzer

2-12 Operating manual – A5E00222135-01

The gas analyzers can be operated from a
control system or a separate PC using the
SIMATIC PDM (Process Device Manager)
operator control utility, a program which runs
under Windows XP or Windows 2000 and which
can also be incorporated into the SIMATIC PCS
7 process control system. This means that is
possible to represent in a clear and logical
manner not only the incorporation of the devices
in the system but also the complex parametrical
structure of the analyzers and operating the units
becomes simply a matter of clicking.
The PROFIBUS users organization (PNO) is an
independent international body representing the
interests of a large number of manufacturers and
users. Alongside services such as giving advice,
training and the certification of devices, its
primary duty is the further development,
standardization and promotion of PROFIBUS
technology. Definition of a mandatory
functionality for a class of devices in a profile is a
necessary condition for devices from different
manufactures behaving in a uniform manner –
what is known as "interoperability”. At the end of
1999 a mandatory profile for analysis devices
was established down thereby ensuring that all
devices in a system with PROFIBUS capability
will work together.

This profile defines the functionalities of the analysis
devices in a block model. For example, the device
block (physical block) describes the measurement
procedure, the analyzer and manufacturer names,
serial number and operational state (in operation,
under maintenance). Different functional blocks
contain the execution of specific functions such as
measured-value processing and alarm response. The
transducer blocks describe the functionality of the
measurement procedure itself as well as control of
the procedure – for example, preprocessing of a
measured value, cross-corrections, curves,
measuring ranges and also switching and control
operations. Data transmission between bus users is
defined in protocols.

Here a distinction is drawn between cyclic and
acyclic services. Time-critical data, such as
measured values and states, are transmitted
using cyclic services. Acyclic services, on the
other hand, permit device parameters to be
interrogated or modified during operation.

All of the gas analyzers in Series 6 (ULTRAMAT
6, OXYMAT 6/ 61, CALOMAT 6, ULTRAMAT 6
and FIDAMAT 6 and also ULTRAMAT 23) have
PROFIBUS capability once fitted with an optional
plug-in board (which can also be retrofitted) (see
also the electronics spare parts from page 7-3
onward of the spare parts list).

AK interface

AK is an interface which is not a standard
integrated part of Series 6 gas analyzers but
which can only be used when an additional board
is fitted. It can be ordered under this order
number:
C79451-A3474-B61

Unlike PROFIBUS and ELAN, communication
with AK is only possible between a device and a
PC and takes place on the master-slave
principle. The devices transfers data only upon
being so requested by a command telegram, and
here it can only process and reply to one
command at a time.

Fig. 2-6: Basic structure of an AK interface

The AK menu can be accessed via function 88
and the parameters set.

The benefit to the user lies in its numerous
functions which are primarily required in the
automotive industry in order to carry out
relinearization,

The principle behind the connection technology
corresponds to an RS 232 and is shown in the
diagram below.

3.1 Safety instructions

Warning

It is essential that you observe the following information and instructions!

Hazardous voltages

Certain parts of this device are carrying hazardous voltages. Before the
unit is switched on, the housing must be closed and grounded.
Failure to comply may result in death, physical injury or damage to
property.
In this regard you should also read and comply with the section entitled
"Electrical connection” on page 3-5.

Poisoning hazard

When toxic or corrosive gases are being analyzed, the exhaust gases
must be taken off in such a way that persons present are not exposed to
any danger. Exhaust gas lines must be made of material which is
resistant to the sample (see also "Design of housing and FID” on page 2-

4).
Failure to comply may result in serious symptoms of poisoning or even
death.

Explosion hazard!

Use of the FIDAMAT 6 gas analyzer for measuring operationally
explosive mixtures is not permitted. If the unit is to be used for measuring
flammable gases which in combination with air or oxygen could form an
explosive mixture, special explosion-protection measures will need to be
taken.

Combustion hazard

During operation the interior of the unit's oven reaches a temperature of
around 200°C. With the aid of function 2 not only the actual temperature
of the oven but also any other temperature setting may be accessed.
Once the unit has been switched off, temperatures fall only at a very slow
rate. This is why the oven is not accessible to operating personnel during
normal operation.
Protective gloves must always be worn during maintenance work. Note
too that hydrogen burns colorlessly. Failure to observe this may result in
serious burns.

Flushing the housing

In accordance with details in the technical data starting on page2-14,
there may be what is to be regarded as a limited escape of flammable
components from leaks in the sample path. With the FIDAMAT 6
there is no need to flush the housing provided it has been ensured
that there is a natural exchange of air from the environment.

Note

However, this does not apply to toxic or corrosive gases! In this regard
the maximum allowable workplace concentration figures must be
observed.

Installation instructions

FIDAMAT 6 gas analyzer
Operating manual – A5E00222135-01 3-3

3.2 General installation requirements

Installation conditions A location as free as possible of vibration should be selected for

installation.

Make sure that the permissible ambient temperature of 5°C – 45°C is
observed during operation (see also "Technical data” on page 2-14).
You should also ensure that the unit is not exposed to direct sun light.

If the FIDAMAT 6 is installed in a cabinet or desktop casing, it must be
accommodated on support or telescopic rails. It can also be fitted into a
swing frame. Mounting the unit by its front end is not satisfactory since the
unit's own weight will place too great a load on the chassis.

Due to the unit's great weight the mountings will need to be sized
correctly. Use all four screws to fix the housing in place.

Ventilation

Although the FIDAMAT 6 has an internal fan you still need to ensure

adequate ventilation. If several devices are installed in a single cabinet,
the FIDAMAT 6 should be fitted as the highest-positioned device due to
the great amount of heat it gives off. If this is not possible, a space of
about 4 - 5 cm (1 height unit) must be left above the unit.

Gas connections Bulkhead connectors with an external pipe diameter of 6 mm or ¼"

(Swagelok) are provided as gas connections. Gas connection
assignments are given in both the gas circuit diagrams and the
identification labeling on the rear panel of the unit.

Electrical connections All connecting cables (apart from the mains power line) must be shielded.

The connected cables are shielded via the plug-in connectors.
The core cross-section should be 0.5 mm². Cables of the type
JE- LiYCY...BD are suggested. The line length of the analog outputs
depends on the load.

Caution

When installing the wiring please observe that the device is emitting
heat. Therefore there must be a minimum distance of >2 cm between
wiring and device.

Maintenance In order to ensure that the unit is not only electrically safe but also is

functionally reliable, the FIDAMAT 6 should be given an annual servicing.
In particular, the gas path inside the unit (containment system) must be
checked for leaks. After each servicing of the containment system, a leak
test must be carried out (in this regard see "Checking for leaks” on
page 4-3).

Installation instructions

FIDAMAT 6 gas analyzer

3-4 Operating manual –A5E00222135-01

Sample gas line For gas entry and exit there is a directly heated entry (sample) and a

directly heated outlet. Separate heated sample supply lines each require
their own energy supply and temperature regulator.
The hexagon of the bulkhead connectors is seated in an anti-rotation lock.
When tightening up the union nuts on the connectors make absolutely
certain that they are properly locked using a suitable wrench. Failure to do
so will mean the risk of the gas line becoming leaky.

The sample is drawn in by a diaphragm pump (approx. 1 l/min) and if at
all possible should be made available at atmospheric pressure.
Notwithstanding this, the analyzer can also be operated at a constant
over- or underpressure of up to 100 hPa.

Exhaust gas line

The greater part of the sample delivered by the pump is routed via a so-

called bypass to the exhaust gas outlet. If the exhaust gases are
flammable, toxic or otherwise injurious to health, it is essential that they
are taken off using the appropriate measures.

If the exhaust gas is to discharge into a collecting main the following
points should be noted:

•

The flow resistance in the collecting main should be kept low by
means of either the shortest length of pipe possible or a transition to
a larger diameter.

•

The exhaust gas line must not be subject to rapid pressure
fluctuations. If this is not the case, you will need to put in a separate
exhaust gas line or fit a damping vessel with throttle value (>1 l)
between the analyzer and the exhaust gas line (pneumatic low-pass
filter).

•

To prevent blockages of the exhaust gas line (for example, due to
condensed water) and thereby damage to the unit due to water
formation, all parts of the line must have a downward gradient. To
this end, it is advisable to install a siphon as a water trap.

Fig. 3-1: FIDAMAT 6, gas and electrical connections

Installation instructions

FIDAMAT 6 gas analyzer
Operating manual – A5E00222135-01 3-5

Sample path within the unit
(containment system)

Sample-wetted materials must be resistant to the sample. Materials used

for the seals are quartz, stainless steel 1.4571, graphite and / or PTFE.

Regular inspections for leaks must be carried out to check the integrity of
the containment system. If the result is negative, the cause of the leaks
must be corrected before you can use the analyzer. A possible remedy in
this case is to fit new seals.

After each servicing of the containment system, a leak test must be
carried out (in this regard see "Checking for leaks” on page 4-3).

Pressure sensors The FIDAMAT 6 has two internal pressure sensors for measuring the

sample pressure (= combustion air pressure) and the hydrogen pressure.

Maintenance Both the electrical safety and the serviceability of all unit components

must be checked regularly. For this reason the FIDAMAT 6 needs an
annual servicing.

The servicing frequency can be reduced in individual cases on the basis
of the owner's judgment if no negative effects on the sample-wetted seals
are to be expected from chemical attack.

The operator panel (viewing window and keyboard) should only be
cleaned by wiping with a damp cloth.

3.3 Gas conditioning

Sample The sample is drawn in through a sample filter heated to 200°C in order to

refilter the sample gases. The filter is made of sintered metal (CrNi steel),
has a pore size of 3 µm and a surface area of 3 cm².

Note

Sample gases must be free of dust when they enter the analyzers.
Condensate should be avoided. For this reason, it will in most
application cases be necessary to use a gas conditioning device
suitable for the measurement task in question.

Supply gas

The supply gases (hydrogen, combustion air) must have a purity level of

5.0 if correct measurement is to be assured. The purity level will need to
be increased in the case of very low concentrations of hydrocarbons
(<1 ppm). The supply gases must be made available with a input pressure
between 2000 and 4000 hPa rel. The pressure of zero gas and test gas is
around 3000 hPa in each case. Higher pressures will result in increased
gas consumption while lower pressure could on the other hand lead to
incorrect calibration (calibration) since sample could also be drawn in as
well.

3.4 Electrical connections

Warning

When carrying out electrical installation, you should observe the
provisions of VDE 0100 or an equivalent international standard relating to
high-voltage systems with nominal voltages below 1000 V.

Failure to comply with these provisions may result in death, physical injury
or damage to property.

3.4.1 Power supply

• An inlet connector for non-heating apparatus is supplied with the unit
and should only be connected to the mains supply line by qualified
personnel (see "Qualified personnel” on page 1-5). The mains supply
line must satisfy the regulations and requirements applicable at the
place of installation and also be provided with a protective conductor
at housing potential. The cross-section of each core must be 1 mm².
The phase-carrying connection cable must be connected at the
marked location in the plug.

• The power cable must be routed separately from the signal lines.

• A power isolator device must be provided in the immediate vicinity of

the unit (load capability shown on nameplate). It must be easily
accessible and have identification labeling.

• A check should be made to ensure that the mains voltage present is
the same as specified on the nameplate.

Caution

Due to the heat radiation a minimum distance of one inch from the
housing must be observed when wiring the device.

3.4.2 Connecting the signal lines

Warning

Signal lines should only be connected to units which are safely electrically
isolated from their auxiliary power.

Installation instructions

FIDAMAT 6 gas analyzer
Operating manual – A5E00222135-01 3-7

• With the FIDAMAT 6 the signal lines are connected to the SUB D
connectors at the rear of the unit.

• The connection cables to the relay outputs, the binary inputs and the
analog inputs and outputs must be shielded. They should be
connected to the corresponding trapezoidal plug (SUB-D plug) as
shown in the allocation lists (see "Pin assignments” on page 3-8).

• The reference ground of the analog inputs is the housing potential.

• The analog output is floating.

• The shielding of the interface line must be connected to housing

potential. The cable shielding must have a large-area connection
with the shielding of the SUB D plug. The cross-section of the cores
should be 0.5 mm². The interface line should not exceed 500 m in
length.

All connecting cables (apart from the mains power line) must be
shielded.

The cable shielding of the connected lines must be applied over a
large area and without any gaps at the respective threaded connec­tions.
The core cross-section should be 0.5 mm². Cables of the type
JE- LiYCY...BD are suggested. The line length of the analog outputs
depends on the load.

In accordance with details in the technical data, there may be what is to
be regarded as a limited escape of flammable components from leaks in
the sample path. With the FIDAMAT 6 there is no need to flush the
housing provided it has been ensured that there is a natural exchange of
air from the environment. Your attention is particularly drawn to this in the
case where the analyzer is installed in a cabinet.

Warning

However, this does not apply to toxic or corrosive gases! When working
with corrosive or toxic gases the device must be flushed

Start-up

FIDAMAT 6 gas analyzer
Operating manual – A5E00222135-01 4-3

4.2 Start-up preparations

Position of unit The FIDAMAT 6 may only be operated in a vertical position.

Gas conditioning Gas preparation takes place via a heated sample gas filter

(approx. 200°C) with a pore size of 3 µm and with a very limited capacity.
For this reason, samples with a high degree of contamination must be
prefiltered before entering the analyzer.

Check for leaks A leakage inspection should be conducted after any maintenance activity

affecting the flame ionization detector (FID) or the gas path. This is done
as follows:

FID

1. Connect

the sample gas outlet (exhaust gas) to a relative

pressure manometer

(0 - 1000 hPa, resolution 0.1 hPa)

2. Apply an overpressure of about 950 hPa at the sample entry and
close off.

3. Wait two minutes or so, until pressure equalization has occurred and
then make a note of the pressure.

4.

Wait another minute and then read off the pressure
The gas path is satisfactory as far as leaks are concerned when
the pressure drop within a minute does not exceed 10 + 2 hPa.

Note

The temperature of the gas path, including the FID, must remain constant
while this measurement is being taken.

Test conditions: The pressures given are relative pressures.

Test medium: Synthetic air (sample path must not become contaminated)

Test pressure: Operating pressure x 1.5 (operating pressure = 500 hPa)

Unit electrically switched off:

Test pressure [hPa]

Permissible pressure drop ∆ p [hPa]

Operation Before connecting up and switching on the unit, the operator must have

familiarized himself with how the unit is operated (see on page 5-2).

Interfaces

Before the unit is used, the interfaces must be correctly assigned and

parametrized (see "Connecting the signal lines” on page 3-6).

Noise damping The output signal fluctuations caused by noise in the measurement signal

can be reduced by means of function 50. Among other things, this
function allows you to parametrize a low-pas filter which can be assigned
a time constant of up to 300 s.

Temperature influence Make sure that the permissible ambient temperature of 5°C – 45°C is

observed during operation (see also "Technical data” on page 2-14).

Pressure influence If measurement is carried out externally, the unit will carry out an

automatic pressure correction. If there are pressure fluctuations within the
unit, pressure compensation will be carried out automatically.

Start-up

FIDAMAT 6 gas analyzer
Operating manual – A5E00222135-01 4-5

4.3 Start-up and operation

Check Before switching the unit on, check to see that hydrogen, combustion air, zero

gas and test gas are connected and the required pressures are present.

Switching on
mains power Shortly after switch-on, the measured value display appears on the LCD

screen. Above this, on the top line, is the status display (Section 5.1).

Warming up

With the FIDAMAT 6 it is necessary to wait for about one hour for the

warming-up phase to finish. During this time, the oven heats up to 200°C
(accessible via function 2 "Diagnostics values”). In contrast, the
measuring cell and FID are warmed up with a delay whereby their
temperature derives from the setpoint temperature of the oven. Next, the
unit automatically checks in turn to see whether the corresponding
pressure of the sample and combustion air obtains and whether the
hydrogen supply is adequate. If this is the case, the flame is ignited
automatically. The flame burns when the flame temperature is 20°C
higher than the oven temperature.

Not until the unit has detected that the flame is burning will the pump be
switched on.

So as not to block the automatic heating-up procedure, the unit must be in
its measurement state. Here the current operational status can be read off
from the bottom line.

4.3.1 Measuring ranges

Measuring ranges and
measuring spans

The measuring spans desired (initial value of measuring range and final

value of measuring range) should be defined using function 41. Analog
current values 0/2/4 mA to 20 mA are assigned to the initial and final
values.
If the same values are assigned for a measuring range's initial and
starting values this measuring range will be deemed non-existent.
The smallest measuring span (MS) is to be assigned to measuring range
1, and so on. In general, the following arrangement will apply: MS1 < MS2
< MS3 < MS4

Setpoint value of zero point The setpoint value for the zero point is entered under function 22. It

applies to all measuring ranges.

Calibration of zero point Zero calibration is carried out with the aid of function 20. Here both the

setpoint value and the actual value are displayed.

Start-up

FIDAMAT 6 gas analyzer

4-6 Operating manual –A5E00222135-01

Electronically suppressed
zero point If the measuring range initial value (ppm,% vol., etc.) is not at

concentration zero, we speak of measuring ranges with suppressed zero
point (for example, 200 - 300 ppm CO). Here 200 ppm is the initial value,
300 ppm the final value, and 100 ppm the measuring span.

Channels with electronic zero-point suppression are physically identical to
non-suppressed zero points. Where they differ is solely in the parametri­zation of the measuring ranges and of the setpoint value for the
suppressed zero point (200 ppm CO, for example).

The characteristic

curve

is stored from zero to the characteristic final value (as stated on

the nameplate). Units with non-suppressed zero points can be repara-

metrized subsequently to suppressed zero points by modifying this para­meter (functions 22 and 41). It should however be noted that influences
such as noise, temperature and pressure errors are magnified by the
factor

F =

Final value of smallest measuring range

Final value of smallest measuring range – initial value

Here F should not exceed a value of 7. In general it is recommended to
increase the smallest measuring span by about 30%.

Span setpoint value The setpoint value for span should be checked under function 22.

The setpoint value displayed must be the same as the test gas value. If
this is not the case, the values must be made to coincide with the aid of
function 22.

With a total calibration, the leading measuring range should be selected.

The setpoint values must be as far away as possible from the zero point
(at least 60% of the corresponding full-scale value). The corresponding
test gases should be made available for the span calibration. The setpoint
value is input under function 22.

Changing measurement
ranges

For the largest measuring range (according to the nameplate) the

linearized curve is saved in the memory. If the largest measuring range is
changed (function 41) this final value must not be exceeded.

Dropping below the smallest measuring range (according to the
nameplate) is not permitted as in this case noise and the influence of
temperature on the measured value would increase relative to the
measuring range and reproducibility and drift behavior would deteriorate.

Operating manual – A5E00222135-01 4-7

4.3.2 Calibration

Zero calibration Zero calibration is carried out with the aid of function 20. Here both the

setpoint value and the actual value are displayed.

Single and total
calibration Single calibration means that each measuring range is adjusted with its

own test gas. This is to be recommended when the changeover ratio of
the measuring spans exceeds 1:10.

With total calibration only the leading measuring range (function 22) is
adjusted; the other measuring ranges are "pulled in” via the changeover
ratio.

Total calibration can be activated or deactivated with the aid of function

23.

Next, select function 21 and carry out the calibration desired. In this
regard, note that this function cannot be selected unless AUTOCAL is
disabled.

Total calibration therefore means that all measuring ranges are adjusted.
With single calibration, the procedure described above has to be repeated
separately for each measuring range with the corresponding test gases.
(Under function 22 a test gas must be specified for each measuring
range!)

Calibration of zero point,
span Apply zero gas or test gas to the unit at 30 – 90 l/ h (0.5 – 1.5 l/ min).

Note here also the input pressures on page 2-14. Zero point calibration is
carried out with the aid of function 20, span calibration with function 21.

Measured value display (measurement mode)

Entry into the main menu

The measurement component, furnished with a rightward pointing arrow
(►), appears on the right-hand side of the screen. A soft key is assigned
to this component. Pressing this soft key calls the main menu.

The main menu consists of the following sub-sections (sub-menus).
To their
right is shown the corresponding code level:

Diagnosis Not coded
Calibration Code level 1
Measuring ranges Code level 1
Parameters Code level 1
Configuration Code level 2

The code for level 1 is factory-set to "111” and that for level 2 is set to
"222.”

Entry into a
sub-menu

Once a sub-menu has been selected, you will be asked for the code for

the operator level (exception: the "Diagnosis” submenu is accessible
without restrictions).

Decoding level 2 also decodes level 1.
With decoding, signaling to the outside can take place via a relay contact
provided a corresponding relay has been configured via function 71 with
CTRL. The warming-up and calibration phases of the unit are also
signaled via this relay contact.

With decoding the measured value memory is also activated, provided it
was set under function 77. The coding of the unit is to be seen on the
display (Fig.:

Measured value display) as the symbol ■ CODE,

decoding with

□ CODE.

Return to
measuring mode

From any location in the menu structure, pressing the MEAS key will take
you back immediately to measuring mode. Any input you may have
started will be aborted.

Before the jump, the question shown on the left will appear.

Pressing the YES or NO soft keys takes you back to measuring mode.
YES causes the changes to be saved in the main memory of the
parameter memory, NO discards them.

Pressing the ESC key takes you back to the last function screen.
Changes are accepted without checking with you first.

Coding the unit

Following a return via ESC or MEAS to measuring mode, the unit can
be coded again by pressing MEAS again

(■ code) and thus returned to measuring mode. All states brought into
existence with decoding are thereby cancelled.

Quick selection of
functions In the case of frequent operator activity a "power user” feature has been

implemented to allow the user to go directly to the desired function screen
from the "Measured value display” screen. This allows direct access to the
desired settings by inputting functions. This simply bypasses menu levels.
However these functions can only be launched from measuring mode and
include the following operator steps:

• In measuring mode ("Measured value display” screen), input
the number of the desired function using the number key.

• Press the soft key with the ► arrow.

• If the desired function is protected by a code, you will be

asked to input the code (see "Entry into the main menu”).

5.3.1 Diagnosis

When the diagnostic functions are selected in the main menu by pressing
the first soft key ("Diagnosis”) the adjacemt display appears.

Access to diagnostic functions is not restricted. For this reason you will
not be asked for the code.

Every unit provides the following diagnostic functions:

1 Factory data When this function is selected, important manufacturer's data for the unit

are displayed:

Motherboard:

• Firmware no.:
Order number of the software held in the EPROM for the
motherboard

• Order no.:
Information about ordering data for the unit

• Serial no.:
Information about date of manufacture and unit serial number

• Article status:
Information about hardware configuration of the unit

• Software status and date
Information about the unit's functional scope at the motherboard

2 Diagnostic values The most important diagnostic values are listed under function 2. They

may allow conclusions to be drawn for evaluating setting activities or
errors.

3 Logbook In the logbook will be found a list of all errors which resulted in a

maintenance request (W) or a fault message (S). (see also on page 6-5
"List of maintenance requests”)
Limit alarm (LIM) and function check (CTRL) are also recorded.
These, however, do not trigger a maintenance request or fault message.

The logbook contains a maximum of eight pages, each of which can hold
four messages. It works on the principle of the cyclic buffer – in other
words, when all eight pages (all 32 slots) are occupied, the oldest
message will be overwritten.

Logbook entries can be deleted or locked (function 60) and even switched
off individually (function 87).

Note

If an error occurs and its error message has been switched off with
function 87, there will be no reaction at an interface which may have been
configured. This applies to the ELAN interface and also to the analog
output and relay output.

Operation

FIDAMAT 6 gas analyzer
Operating manual –A5E00222135-01 5-11

In the case of maintenance, function 110 Diagnostic service should also
be taken into consideration. This menu is however only accessible to
maintenance personnel.

4 Display measurement
ranges

The measuring ranges defined under function 41 are listed under

function 4. However, they cannot be modified in this menu.

5.3.2 Calibration

If at all possible, calibration should be carried out using test gases which
very closely resemble the sample both in composition and concentration.
If the measuring task is to measure hydrocarbons in nitrogen, a hydro­carbons in nitrogen test gas should also be used. If, for example, propane
in synthetic air were to be used here, the measurement result would be
falsified by the response factor of the methane compared with the
propane and by the oxygen error.

The FIDAMAT 6 provides both manual and automatic calibration
(AUTOCAL: function 24). The latter is only possible with the aid of an
optional board which in addition contains eight binary inputs and eight
relay outputs.

Setpoint values for zero-point and span calibration must be set under
function 22.

20 Zero-point calibration

Calibration of the zero point is carried out for all measuring ranges
simultaneously even if the span of the measuring ranges is being adjusted
individually.

The calibration procedure should not therefore be initiated until the
measured value (actual value) has stabilized following addition of the zero
gas.

If the measured value fails to settle, the time constant (function 50) should
be increased before carrying out calibration.

Operation

FIDAMAT 6 gas analyzer

5-12 Operating manual –A5E00222135-01

21 Span calibration of

Single calibration:

The display shows as many measuring ranges as was previously defined
via function 41. The adjacemt display therefore represents an example of
single calibration of four measuring ranges.

If measuring range 3, for example, is to be adjusted, the corresponding
softkey should be pressed.

The setpoint value and the current (ACTUAL) value for measuring range 3
appear on the screen.

Once the actual value has stabilized, the calibration procedure can be
started by pressing the fourth soft key. The actual value is now brought
into agreement with the setpoint value.

In the case of an inadvertently incorrect calibration (after using the wrong
calibration gas, for example), pressing the "ABORT" soft key will reload
the original calibration.

Total calibration:

Total calibration means that all measuring ranges are adjusted
simultaneously. The "leading” measuring range is defined under function
22 (see also menu 23 "General and single calibration”). It makes sense to
select the largest measuring range as the leading range.
The setpoint value and the current value for the "leading” measuring
range appear on the screen.

Once the actual value has stabilized, the calibration procedure can be
started by pressing the fourth soft key. The actual value is now brought
into agreement with the setpoint value.

In the case of an inadvertently incorrect calibration (after using the wrong
calibration gas, for example), pressing the "ABORT" soft key will reload
the original actual value.

22 Setting setpoint values

The adjacent example to the left shows setpoint value input in the case of
total calibration. The fourth measuring range has been chosen as the
leading measuring range.

In the case of single calibration, it is not possible to specify the leading
measuring range.

Operation

FIDAMAT 6 gas analyzer
Operating manual –A5E00222135-01 5-13

23 Total and
single calibration:

This function is used for selecting general or single calibration of the
measuring ranges.

With total calibration a "leading measuring range” is adjusted and all of
the other measuring ranges are "pulled in” via the changeover ratio.

If this function is not activated (see illustration), each measuring range will
be adjusted individually.

24 AUTOCAL

Automatic calibration (AUTOCAL) cannot be carried out unless the unit
has an additional electronic module (optional board).

If it does not and an AUTOCAL parameter is selected, the corresponding
message will be shown on the display.

AUTOCAL / check
operating mode

This subfunction allows you to parameterize various AUTOCAL operating
modes.

AUTOCAL / Check on / off

When the "AUTOCAL off” state is active (shown as

□) it will not be

possible to operate the "AUTOCAL Start by cycle” (parameter) or
"AUTOCAL Start by binary input” switches.

Even "AUTOCAL run once”
is switched off. The cycle time continues to run. Nevertheless no
automatic calibration is initiated.

AUTOCAL / check Start by cycle
AUTOCAL can be activated to use a regularly repeating cycle provided

the "Time between two AUTOCALs” has been set.
"AUTOCAL – check” is used for checking the calibrations. As with
"AUTOCAL”, the sequence parameterized in the "AUTOCAL sequence”
menu is carried out. In contrast to "AUTOCAL” no new calibrations are
however performed, but deviations from selectable calibration tolerances
are checked.

Operation

FIDAMAT 6 gas analyzer

5-14 Operating manual –A5E00222135-01

AUTOCAL / check Start by binary input
AUTOCAL can be activated via a binary input provided one has been

configured with the aid of function 72.

AUTOCAL run once
In the "AUTOCAL on” state, an AUTOCAL sequence can be started at

any time by means of the "AUTOCAL run once” soft key – provided the
unit is in the measuring state. A run initiated in this way does not have any
influence on the time cycle of an AUTOCAL run – in other words, the
cycle time continues to run independently of this.

After AUTOCAL initiation, this item disappears until the process has
completed.

AUTOCAL abort
An automatic calibration run which is in progress can be stopped at any

time by means of the "AUTOCAL abort” soft key. This results in all
calibration data so far obtained being discarded and the calibration data
valid before AUTOCAL started (zero point and span) being used as
previously.

Aborting in this way has no effect on the time cycle. All valid calibration
events are retained.

AUTOCAL sequence
This subfunction allows you to group several calibration phases into one

AUTOCAL sequence.

The sequence used for automatic calibration can be defined as you see
fit. It is possible to put together a sequence consisting of as many as
twelve different phases.

In addition to inputting a zero gas and up to four test gases for each
component, you can also program in flushing with sample gas, and a
sample gas intermediate operation period as well as a signaling contact.
This signaling contact will be available provided it has already been
assigned to a relay output by function 71.

Sample gas intermediate
operation A sample gas intermediate operation period may become necessary

if the system is only permitted to leave measurement mode for a very
specific time. If the necessary flushing times then add up to a period
greater than the permitted outage time, there must be a return to
measurement mode between the individual calibration runs.

Signaling contact The signaling contact can, for example, be used for starting an

automatic calibration run in a second unit or for signaling the start or
end of an AUTOCAL run.

Relay outputs If relay outputs have been defined for sample, zero gas, test gases

and / or measurement or calibration (function 71), the corresponding
external solenoid valves will be operated via these outputs. The same
applies to the "AUTOCAL" signaling contact as well – this is closed for
about one second when the command is being executed.

Operation

FIDAMAT 6 gas analyzer
Operating manual –A5E00222135-01 5-15

Example:
The following sequence is to be programmed:

1. Zero gas calibration, with zero gas flushing after 15 minutes

2. Calibration with test gas 1, with flushing with test gas after
10 minutes

3. Flushing with sample: 8 minutes

4. Sample gas intermediate operation: 30 minutes

5. Calibration with test gas 2, with flushing after 8 minutes

6. Calibration with test gas 3, with flushing after 8 minutes

7. Calibration with test gas 4, with flushing after 10 minutes

8. Flushing with sample: 8 minutes

9. Momentary signaling contact so as to be able to start
"AUTOCAL" in another unit or channel.

Note

The FIDAMAT 6 only has one connection for test gas. Additional test
gases will need to be connected up externally and switched using
external valves.

Zero gas 2 is not used with the FIDAMAT 6!

AUTOCAL / check Cycle parameters

With this subfunction various time constants for activating a cyclically
repeating AUTOCAL run can be parameterized.

• Time between two AUTOCAL cycles.
Any setting between 0 and 1 (hour) will be accepted by the unit. Here
a "0” does not correspond to any AUTOCAL cycle.

• Time until the first AUTOCAL run (from time when setting made).
If a "0” is input here and AUTOCAL is switched on (see "AUTOCAL
on / off”) the analyzer will start the AUTOCAL sequence immediately.
If AUTOCAL is switched off, the unit will not start an AUTOCAL
sequence unless AUTOCAL is switched on within a minute of the "0”
being input. If this does not occur, from time the "0” is input the entire
time between two AUTOCAL cycles will be cancelled.

This internal clock will therefore run even when AUTOCAL is
switched off! It starts the first time the unit is switched on, and needs
to be reset to the current time via function 58.

• Number of cycles before test-gas calibration is performed.

With every AUTOCAL run the zero point is calibrated. If, in order to save
on test gas, the span is not to be adjusted as well every time the zero
point is calibrated, a value greater than 1 must be entered in the line
"Perform test gas calibration every : : cycle.”

Note

As long as AUTOCAL is activated (AUTOCAL

■), access to functions

20 and 21 will also be blocked.

Should you still attempt to access the

functions, a corresponding message will appear in the display.

5. Following a fault-free AUTOCAL run they will both be reset.
W10 will be retained in the logbook.

5.3.3 Measuring ranges

When the measuring range functions are selected in the main menu by
pressing the third soft key ("Measuring ranges”) the adjacemt display
appears.

40 Select measuring ranges

It is possible to select a fixed measuring range or to switch over to
automatic measuring range changeover. All possible selections are
subject to mutual interlocking.

Automatic measuring range changeover is possible under the following
conditions:

• At least two measuring ranges must be available. A measuring
range is deemed present when:

• measuring range initial value ≠ full-scale value

• The measuring spans must be made larger

• The measuring range must adjoin each other or overlap

This yields the following permitted measuring range arrangements which
are shown in the following diagrams:

Operation

FIDAMAT 6 gas analyzer

5-18 Operating manual –A5E00222135-01

Only two measuring range types are distinguished:

type A: The full-scale value must be less than the full-scale value which follows it. This

means that the upper measuring range limit is higher with each successive
measuring range.

smr : start of measuring range
emr: end of measuring range
LP: lower changeover point: select

smaller measuring range

UP: upper changeover point: select

larger measuring range

The following applies to measuring range changeover:

Operation

FIDAMAT 6 gas analyzer
Operating manual –A5E00222135-01 5-19

If the upper changeover point (OU) is crossed, the next largest available
measuring range will be selected. If the lower changeover point (UU) goes below
that of the next smallest available measuring range, this will be selected. The UU
is located at 80% (HystA) of the measuring range. The OU is located at 90%
(HystE) of the measuring range.

type B: The full-scale value must be greater than or equal to the full-scale value

which follows it. Since the measuring spans must at the same time become
larger, the measuring range initial values of the following measuring ranges
must always be smaller.

smr : start of measuring range
emr: end of measuring range
LP: lower changeover point: select

smaller measuring range

UP: upper changeover point: select

larger measuring range

The following applies to measuring range changeover:

If the upper changeover point (OU) is crossed downwardly, the next largest available measuring range will
be selected. If the lower changeover point (UU) of the next smallest available measuring range is exceeded,
this will be selected.

The UU is located at 10% (100% - HystE) of the measuring range.
The OU is located at the start of the measuring range (mba).

41 Define measuring ranges

A maximum of four measuring ranges can be defined whose initial values
are assigned to the lower value (0/ 2/ 4 mA) and whose final values are
assigned to the upper value (20 mA) of the analog output.

If the message "Measuring ranges implausible” appears, this means that
automatic measuring range changeover is not possible.
If the initial or final value is 0, the measuring range will be switched off.

Operation

FIDAMAT 6 gas analyzer

5-20 Operating manual –A5E00222135-01

5.3.4 Parameters

Following selection of parameter functions in the main menu by pressing
the fourth soft key ("Parameters”) the adjacemt display appears, showing
parameter functions 50 to 53. If you press the fifth soft key ("…more”), this
will display parameter items 54 to 61 instead.

50 Electrical time constants With the aid of this function various time constants which reduce noise

can be set. The reduction feature corresponds more or less to a low-pass
filter with the corresponding time constant. The display delay is shown in
90% time.

The time constant ti is effective within an action interval which is to be
parameterized and which is defined as a percentage of the smallest
measuring span. On the one hand it damps minor changes in measured
value (noise, for example) but has no effect immediately the measured
value exceeds the action interval. In this case the measured value is
damped by the external time constant ta.

Values up to 100% can be parameterized for the action interval and
values up to 300 s for the time constants ti and ta. A low display delay
(90% time) can still be achieved by a skilful combination of these three
parameters despite a high level of noise suppression.

The effect of the damping parameters set can be observed on the bottom
line where the measured value is shown "live.”

51 Limits For each measurement component the unit can monitor up to four limits

which can be assigned to the measuring range as desired.
Any relay can be assigned to each limit (see function 71).

Only positive limit values up to 100% can be parameterized.

Furthermore, you can specify whether a limit alarm should be activated
when the limit value entered is exceeded or fallen below.

The limit value is assigned to the measuring range by repeatedly pressing
the third soft key. Here pointers travel above the boxed measuring range
identification numbers and indicate the measuring ranges where limit
monitoring is to be activate (in the example to the left this is measuring
range 3).

Operation

FIDAMAT 6 gas analyzer
Operating manual –A5E00222135-01 5-21

Limit monitoring can be switched off individually for any limit value (see
also function 52).

Tripping of a limit relay is recorded in the logbook (function 3). As soon as
the cause of this disappears, the limit relay will reset automatically.
If you press the fifth soft key ("…more”), the program will jump to the next
limit screen.

52 On / off functions

Unit-specific on / off functions can only be accessed via the first
component.
This menu allows you to switch off in a simple manner the functions which
are listed in the adjacemt display.

This simplified operator action means that the longer routes through the
various menu levels are not needed for these functions. However, for the
sake of clarity, the function numbers are still quoted.

Activated functions are indicated by ■, inactivated by □. If you press

the fifth soft key ("more”), the program will jump to the next screen.

In addition to the functions listed in Table 5-2, additional maintenance
functions can be accessed with the aid of function 52. These are reserved
for the use of maintenance personnel only and are hidden until the
maintenance code (code level 3) is input.

53 Status messages

With the aid of this function a maximum of three different states can be
shown in the measured values display.

Functional check shows the current state of the unit (for example,
warming-up phase, calibration, and so on) or which actions the operator
should carry out (for example, decoding the unit). After quitting a menu,
press the MEAS key twice. If you do not do so, the analog output will
remain with the fault current.

Note

If functional check is active, this could result in falsification of the
measured value. Since the functional check is no longer displayed, the
measured value will have to be checked.

Table 5-3: Status message The status type "Code” always appears on the status line. Should a

fault occur during operation, the message "Maintenance request”,
"Fault” and "Measurement protection” will appear on the status line,
depending on the weighting given to the fault. This message is
displayed in alternation with the status messages.

In addition, with communication via the ELAN interface – also alternating
– the message "Remote” will appear, together with the unit state.

54 Graphic
measured value representation

This function allows you to track on screen the measured value time
curves for the last 10 minutes or 24 hours.

Following selection of a time axis (time period) the measured value is
plotted against the time axis. The very latest measured value is located at
the extreme left of the time axis at t = 0.

Operation

FIDAMAT 6 gas analyzer

5-24 Operating manual –A5E00222135-01

Under "Parameters” a specific measuring range can be assigned to the
measured value axis. In addition there is also the possibility of an
"optimum measured value display.” This means that when this parameter
is activated the program automatically carries out rescaling of the
measured value axis. Here the scale is adjusted to suit the measured
value scatter.

55 Measured-value display

This function allows you to suppress output of negative measured values.

It is also possible to specify the total number of positions and the number
of positions after the decimal point.

It should be noted that no more than five positions can be displayed (the
decimal point counts as one position).

56 LCD contrast

With this function you can adjust the contrast of the display to a brighter or
darker setting.

If the contrast is set wrong, by pressing the third soft key ("Default
setting”) you can restore the contrast set in the factory.

It is also possible to carry out an LCD test by pressing the fourth soft key
("test”). A succession of test images is displayed.

If the LCD was grossly incorrect and the unit is in measured value display,
if you press the key sequence
ENTER, you can restore the default setting.

57 Ignite flame

To get the FID running the hydrogen flame must be ignited.
This is done via function 57.

Ignition is activated  or deactivated  by pressing the second hot key.
In addition, the temperature of the flame and of the sample stream are
shown on the display.
When the flame is burning, "Flame burning” appears on the display. If the
flame goes out, this message disappears.

58 Date and time

With this function you can set the time and date precisely.
When the function is called, the presets shown in the screen shot on the
left appear in the display.

The cursor will already be standing on the first position of the date display
which can be changed in the order day, month, year. The same procedure
applies to the time (hours, minutes).

The unit has a system clock which is not protected against power failure
(not a real-time clock).

Attention

When switched off, the clock remains at a standstill and is not updated.

The main importance of the settings is for trouble-shooting. With the aid of
the time and date it is easier to classify faults which have occurred and
which are always recorded in the logbook (function 60).

By pressing the third soft key ("Set clock”) the data which have been set
are taken over for use. They will then appear at the bottom edge of the
screen.

Operation

FIDAMAT 6 gas analyzer

5-26 Operating manual –A5E00222135-01

59 Measurement point changeover

This function allows you to assign a maximum of six measurement points
and to cycle through them automatically.

What this requires is that the measurement point relays have already
been parameterized via function 71 ("Relay assignment”) and these will
then control the corresponding solenoid valves.

A time duration is also assigned to each measurement point relay and is
to be input into the corresponding editing field. For this, values between 0
and 60 (minutes) are possible.

If you press the fifth soft key you can switch measurement point
changeover on and off.

It is also possible to assign a signal relay to each measurement point
relay. This will make possible a measurement point identification which is
separate from the measurement point relay. These signal relays will also
need to be configured via function 71.

60 Logbook settings

With the aid of this function, logbook entries can be deleted or locked (see
also function 3).
The logbook entries can also be deleted by the key
sequence ENTER.
This is, however, only possible in the measured value display.

5 5 55

This cannot be used for suppressing status messages such as
maintenance requests or fault messages which will still be displayed even
if the logbook is locked.

61 Internal valves

With the aid of this function, the internal valves can be operated to control
the gases.

Pressing the corresponding soft key activates  or de-

activates □ the valves.

The internal valves open or close the hydrogen, combustion air, zero gas
and test gas streams.

5.3.5 Configuration

All of the following functions in this block are only accessible via the level
2 code.

Entry menu

When the configuration functions have been selected in the main menu,
pressing the fifth soft key ("…more”) takes you to more configuration
functions.

70 Analog output

With the aid of this function you can determine the lower value of the
measuring range 0 - 20 mA/ 2 - 20 mA/ 4 - 20 mA/ NAMUR = 4 - 20 mA
with limit at 3.8 mA. See also the table below.

The desired value is selected by pressing the soft key assigned to it and
simultaneously the two other values are reset.

In addition, the analog output can be negated; for example, 0 … 100 ppm
THC ≡ 0 ... 20 mA or 0 ... 100 ppm THC ≡ 20 ... 0 mA.

Note

The second analog output is not used.

Negative measured values: Should negative measured values prove to be
unsuitable for further processing, by activating this function you can limit
the negative measured values at the analog output to 0 (or 2/ 4/ 3.8
(NAMUR)) mA. The display continues to show the correct measured
value.

71 Relay assignment

In the basic unit, six programmable relays are available. Their reversible
output contacts (max. 24 V / 1 A) can be used for signaling, controlling
valves, and so on.
Should these six relays be insufficient it is possible to obtain a further
eight relays by installing an additional electronics module (option).

One of the functions listed in Table 5.4 can be assigned to each relay but
each function may only be assigned once. What this means is that a fault
signal, for example, cannot be sent to two relays.

Pin assignments for the individual relays in the non-energized state can
be seen in the assignments diagram "Electrical connections” on page 3-5.
The unit is shipped with the relays preset.

Up to four inputs can be configured in a menu screen. Switching to further
menu screens – and thus to more binary inputs – is always done by
pressing the fifth soft key ("…more”).

72 Binary inputs

In the basic version of the unit, six floating binary inputs are available
['0' = 0 V (0...4.5 V); '1' = 24 V (13 ... 33 V)] which can be configured as
required. Should these six inputs be insufficient, you will need to install an
additional electronics module with a further eight binary inputs (optional).

This is where the manner of functioning of the binary inputs is defined.

With the operating mode NAMUR (■) the binary inputs behave as
shown in Table 5.6 by 'N'.

If operating mode NAMUR is not activated (□), the binary inputs will

behave compatibly with the software edition states of the older version
V4.3.0 (marked with 'X' in Table 5.6).

One of the control functions listed below can be assigned to each input as
required but each function may only be assigned once.

Pin assignments for the individual inputs can be seen in the assignments
diagram 'Electrical connections' on page 3-6.
The unit is shipped with none of the binary inputs preset. Up to four inputs
can be configured in a menu screen. Switching to further menu screens –
and thus to more binary inputs – is always done by pressing the fifth soft
key ("…more”).

Attention

It is essential that any changes made to the configuration of the binary
inputs are saved to the user data memory by means of function 75.
Failure to do so runs the risk of an earlier (and unwanted) configuration
being accessed when 'Load user data' (function 75) is executed.

Operation

FIDAMAT 6 gas analyzer

5-32 Operating manual –A5E00222135-01

Example 1:

The following procedure allows you to adjust the measuring range via the
binary inputs.

1. Zero gas:

The "Zero gas'” relay is opened and thus switches into calibration
mode.

2.

Test gas:
Relay 1, 2, 3 or 4 of the test gas is opened. Distinguishing which
relay is concerned will be made clear by the following differentiation:

•

With total calibration ON:
The relay corresponds to the measuring range number which has
already been selected under function 22 (on page 5-12).

•

With total calibration OFF:
The relay corresponds to the measuring range number of the
measuring range currently selected.

3.

Zero-point calibration is carried out.
This will not take place until the previous steps have been carried out
and the setting "Common zero-point calibration ON” has been
enabled. This means that it is necessary for the unit to be in
calibration mode.

4.

Span calibration is carried out.
Here too it should be noted that the unit must be in measurement
mode for the calibration actually to be carried out. The measuring
range currently selected is adjusted.

The following diagrams should make the procedure clear:

73 ELAN configuration

With the aid of this dialog you can set the parameters for an ELAN
network.

• Channel address:
This is where the channel address can be specified. Addresses from 1
to 12 can be set. In an ELAN network each address may only be used
once.

• Measured-value telegrams (on / off):
The autonomous transmission of measured values cyclically every 500
ms can be switched on or off here.

When putting together your own communication control system, there
is a simple possibility to examine an ELAN telegram.
However, to prevent unnecessary load on the unit and the ELAN
network this function should only be enabled when actually needed.

74 Reset

This function is used for restarting (warm start) (see ”Warming up” on
page 4-5).
Launching this function puts the unit in the warm-up phase. Only when
this phase has ended is the unit fully ready for operation.

75 Save or
load data

With this function you can save user-specific data in the user data
memory.

This should happen, for example, following successful start-up of a
system. All individual settings are then saved and can if necessary be
reloaded ("Load user data”).

This is important when repair or maintenance work is to be carried out on
a unit, for example, or when a new parameterization needs to be tried out.

If necessary, the state as shipped from the factory can be restored with
the aid of the function "Load factory data”.

In addition, this menu incorporates a safety check question. To really load
the data into the memory, you must first answer "Yes” to this question.
Answering "No” aborts.

Attention

It is essential that any changes made to the configuration of the relay
outputs are saved to the user data memory by means of function 75.
Failure to do so runs the risk of an earlier (and unwanted) configuration
being accessed when "Load user data” (function 75) is executed.

The next diagram gives an overview of the interactions between the various memory modules.

Fig. 5-5: Memory modules

76 Suppression of
short-duration fault signals

This function is used for getting rid of unwanted steep-edged faults which
exceed a configurable threshold.

Steep-edged faults ("spikes”) are caused by electromagnetic interference
or occasional mechanical jolts. These faults can be suppressed by
inputting a "blanking-out time” of 0…5 s. The time input causes the last
measured value before a spike occurred to be output and the
measurement result is thus no longer affected.

Input can be made in steps of 0.1 s.

If a change in concentration follows immediately upon a fault, this change
may under certain circumstances be displayed after a delay.
When activating this function, the settings for function 50 ("Electrical time
constants”) must be taken into account since this function is executed
first.

78 Calibration tolerances

The calibration tolerance at the zero point defines in percentage form the
maximum deviation with respect to the smallest measuring span.
The calibration tolerance for span defines in percentage form the
maximum deviation with respect to the current measuring span.
With the aid of this function it is possible to signal changes in the zero
point or span with respect to the last calibration as "maintenance request”
provided a relay output has been configured for "maintenance request”
under function 71.

For this function to be effective the unit must also have been set to "Total
calibration” (function 22).

The calibration tolerance, which can be set between 0 – 99%, relates in
the case of the zero point to the smallest measuring range span, and in
the case of the span to the measuring range span in which total
calibration is carried out.

Let this be made clearer with the aid of an example:
Measuring range 1: 5 ... 100 ppm THC
Measuring range 2: 20 ... 200 ppm THC
Smallest measuring span: 95 ppm THC
Measuring range in which
calibration is carried out: Measuring range 2

Response threshold for zero point 95 ppm THC x 10% = 9.5 ppm THC

Response threshold for
span 180 ppm THC x 10% = 18 ppm THC

If the zero point (or the span) now deviates with respect to the last
calibration performed by more than the configured value, the
corresponding relay with signal a maintenance request.

Operation

Operating manual –A5E00222135-01 5-37

79 Change codes

This function allows you to replace the factory codes ("111” for level 1,
"222” for level 2) to be replaced by your own. If the value "000” is now
entered for a code, code locking is cancelled and access to the
corresponding operator control level is now unrestricted.

80 Selftest

The following three tests will allow you to test the functional serviceability
of the unit.

• Keyboard test:

With the keyboard test all of the keys on the control panel can be
tested.
With the five soft keys on the right-hand edge the corresponding
item can be made to appear or disappear. If a number key or sign
key is pressed, the corresponding number will be displayed in the
editing field on the bottom line of the screen.
Pressing the "INFO" key will issue a plain-text message; here the
"MEAS" and "ESC" retain their return functions.

• Relay and binary-input test

The first screen shot shows the status of the six relay and binary
inputs in a standard unit. If an option board is fitted, on a second
screen page a further eight relays or binary inputs will be found.With
the relay test individual relays can be activated. This is done via the
input field. With a "1” the relay picks up, with a "0” it returns to its
release state. The input field will not allow you to input anything
except "0” and "0.”

After you quit function 80 the relays will have the status which they
had before the relay and binary inputs test was selected.

The current state of the binary inputs is shown in the "Binary”
column.

• Analog test

With the analog test the analog output can be set for testing
purposes to a constant current of between 0 and 24000 µA.

The analog input shows the current input currents in µA.

81 Language selection

With the aid of this function the unit can be switched over to a second

dialog language.

The unit is always shipped with the language ordered. As a rule English is
provided as the second language (if English is the first language, Spanish
will be set as the second).

83 Accompanying
gas correction

With the FIDAMAT 6, accompanying gas correction is not usually

necessary. Should an accompanying gas correction still be required in a
particular case, it will first be necessary to decide what type of
accompanying gas influence is involved. By pressing the first soft key you
can ascertain the type of accompanying gas influence. The following
distinctions are possible:

• No accompanying gas influence

• Accompanying gas correction with constant accompanying gas

influence

• Accompanying gas correction with variable accompanying gas
influence via analog inputs

• Accompanying gas correction with variable accompanying gas
influence via ELAN

Accompanying gas correction will be disabled while an calibration (zero
point or span) is in progress. Once calibration is completed and the unit
has returned to measurement mode, it will be reactivated.

Accompanying gas correction with constant accompanying gas
influence

The unit must be informed of the value of the zero point offset – here
referred to as the accompanying gas deflection.
In addition, you can specify whether accompaning gas correction is only
to apply to certain measuring ranges.

Operation

FIDAMAT 6 gas analyzer
Operating manual –A5E00222135-01 5-39

With a variable accompanying gas the situation is different.
What is concerned here is a variable accompanying gas influence which
can be picked up by a suitable separate gas analysis device and which is
then fed as an analog current or digital signal (via ELAN) into the device
for accompanying gas offsetting.

If accompanying gas correction is to use the RS 485 serial interface
(ELAN), the same inputs should be made as with accompanying gas
correction via analog input.

The following are also required:
Channel number and component number of the accompanying gas analysis
device. The display will show the gas type assigned to the channel and
the component, and also the device status (see also function 82
"Pressure compensation”).

In addition, the parameter "Measured-value telegrams” (function 73) must
be set to "on” for the device which is supplying the correction data.

85 Switch valves

With this function you can switch up to six valves by hand. This is done
via the relays assigned to the individual valves and which are available on
the motherboard and option board.

A requirement is that the corresponding relays must have already been
configured under function 71 ("Relay assignment”). The function "Switch
valves” applies only for the relay configurations "Zero gas”, "Test gas
1…4” and "Sample”.

Only one valve can be switched in each case since the valves are
interlocked.

86 Linear temperature
compensation

The FIDAMAT 6 is temperature-compensated both at the zero point and
also for the span. Should an additional temperature fault occur during
operation it can be compensated with this function.

Temperature compensation at the zero point:

Starting from a mean physical temperature, two different correction
variables can be defined for areas of higher temperature and of lower
temperature.

Temperature compensation in the measured value (sensitivity):

The procedure is the same for the zero point, but the change is with
respect to the measured value.

Operation

FIDAMAT 6 gas analyzer

5-40 Operating manual –A5E00222135-01

Note

Should the zero point deviate towards minus during a temperature
change, ∆ will be positively signed and vice versa. The same applies
to the measured value.

87 Fault on / off

Signaling of maintenance requests and faults (see Tables 6.5.1 and 6.5.2)
can be switched off separately with this function so that there will be no
logbook entry, no status message and no outward-directed signaling.

88 AK configuration

This function cannot be accessed unless the unit has an additional
AK electronics module.

The following parameters of the serial interface can be set:

Baud rate: 300, 600, 1200, 2400, 4800

90 PROFIBUS
Configuration

This function cannot be accessed unless the unit has an additional
PROFIBUS electronics module.

This function allows you to set the PROFIBUS station address. The
address can be set between 0…126.

The configuration behavior of the unit can be set with the "ID number”.
Parameters 0, 1 and 3 can be selected and have the following
significance:

0: Only the PROFILE identification number is acknowledged

positively.

1: Only the device-specific identification number is acknowledged

positively.

3: Only the PROFILE identification number for multivariable devices

(complex analysis devices) is acknowledged positively.

91 Start-up state

With this function you can put the unit into various start-up states.
With this function there is also the possibility of a standby setting. This
is used for relieving the load on the pump without interrupting
operations.

Standby: In this setting the pump is switched off.

Quitting this mode results in the pump
being started and the unit going into
measurement mode.

Time-out This setting allows you to reduce gas

consumption; the pump is switched off.
This mode is quit via the warm-up phase.

Time-out without heating This setting allows you to reduce gas

consumption and output. The pump is
switched off. The heating is also switched
off. This mode is quit via the warm-up
phase.

92 Pressure values

In this menu various values relating to the pressure are output and
can in part be modified.

In the case of the hydrogen pressure the following values are
displayed:

• Set pressure: Displayed automatically

• Max. deviation: If this deviation from the setpoint pressure is

exceeded the unit will quit the measurement
state. This value can be changed.

• Actual pressure: Displayed automatically

Operation

FIDAMAT 6 gas analyzer

5-42 Operating manual –A5E00222135-01

In the case of combustion air pressure there is a further value which
can be input in addition to the functions listed above.

• Min. increase at pump start-up:

When the pump starts the combustion air pressure must rise by this
value for the unit to go into measurement mode. This value can be
changed.

93 Units

The measurement unit can be changed in this menu. Its name cannot on
the other hand be changed.

The following settings for the units are possible:

ppm C

6.1 Maintenance concept

Warning

Before opening the unit shut off both the gas and power supply.

Use the appropriate tools for setting work so as to prevent short
circuits occurring on the electronic boards.

Incorrect assembly, installation or calibration can under certain
circumstance result in dangerous gas escaping. This represents
endangerment of the health of personnel (symptoms of poisoning,
chemical burns) and the unit can also suffer damage from corrosive
attack.

In the case of the FIDAMAT 6, only the pump needs regular
maintenance. It is recommended that the pump diaphragm be
changed every six months.

6.1.1 Pump maintenance

First of all, disconnect the analyzer from the power supply.

Remove the unit cover and open the oven.
The pump can now be taken out of the unit. Care should be taken that the
gas connections at the pump do not get damaged.

A pump defect may be noticed by reduced pump performance and also
increased noise in the measurement signal. Check the filter disk as well –
it could be clogged.

Note

Please observe also Section 'Check for leaks' on page 4-3.

6.1.2 Replacing the filter plate

The filter plate must be replaced at longer or shorter intervals, depending
on the application.
The seal will also need to be changed at the same time in order to
ensure the filter does not leak. After the inserted insulation material has
been removed, the filter is accessible from the rear of the unit.

Note

Please observe also Section 'Check for leaks' on page 4-3.

Maintenance

FIDAMAT 6 gas analyzer
Operating manual –A5E00222135-01 6-3

6.2 Replacing the motherboard and option board

Replacing or installing the motherboard or option board is a simple
matter.

Removal and installation
of the motherboard To remove the board, follow the following procedure:

• Disconnect the analyzer from the power supply

• Unscrew and remove the housing cover

• Remove the data connector from the housing back panel

• Undo the 3 screws which are located between the SUB D connectors

at the rear of the unit

• Pull out the ribbon-cable plug-in connectors from the motherboard

• Carefully remove the motherboard

Removal of option board /
adapter board The procedure is the same as for the motherboard. Unlike the

motherboard, only two screws are used in each case to fix the option
board and the adapter board to the unit back panel.

The reverse order of operations applies to installing the two boards.

6.3 Changing fuses

Warning

Always disconnect the unit from the power supply before changing fuses!

Apart from this, the requirements applicable to operator and maintenance
personnel described in Section 1.6 will apply.

The unit is protected against various influences (for example, mains
voltage, heating) by several fuses.
However, should even just one mains fuse be defective, nevertheless
replace both of them!

To replace the temperature fuse, proceed as follows:

1. Disconnect the analyzer from the power supply

2. Remove the housing cover panel

Maintenance

FIDAMAT 6 gas analyzer

6-4 Operating manual –A5E00222135-01

Warning

During operation the interior of the unit's oven reaches a temperature of
200°C. The actual temperature of the oven may be ascertained via the
diagnostic values.
Once the unit has been switched off, temperatures fall only at a very slow
rate. Protective gloves must always be worn during maintenance work.
Failure to observe this may result in serious burns.

3. Open the oven.

4. Remove the temperature fuse by undoing the fastener clip.

5. Undo the clamp used to connect the temperature fuse and remove it.

The reverse order of operations applies to installing the new temperature
fuse.

6.4 Cleaning the unit

Surface The front panel and control panel can be wiped clean. In explosion-hazard

areas they should only be cleaned by wiping with a damp cloth. As
cleaning agent we recommend water with conventional commercial
detergent added.

Only slight pressure should be applied to the surface of the screen when
cleaning it as otherwise the thin film could be damaged.

It is absolutely essential to ensure that no water gets into the unit
while it is being cleaned.

Interior When the unit has been opened, the interior can, if necessary, be

carefully cleaned with a compressed air gun.

6.5 Maintenance request and fault message

The FIDAMAT 6 is capable of detecting functional irregularities. These
appear on the status line as "maintenance request” or ”fault”. At the same
time they are registered in the logbook and can be viewed there. By
pressing the soft key beside an entry, the corresponding message can be
acknowledged. The messages will reappear if the cause of them has not
been corrected.

When a new message occurs, the record saved in the logbook is shifted
by one memory location. There are 32 memory locations in all. Once all
32 memory locations are occupied, the arrival of a further record (no. 33)
causes the oldest (no. 1) to be overwritten.

Function 60 allows you to lock the logbook and even to delete all of the
messages it contains. This may be useful during trial operation in
particular.
Under function 87 all messages can be switched off separately. During
normal operation use of this possibility is not recommended.

Maintenance

FIDAMAT 6 gas analyzer
Operating manual –A5E00222135-01 6-5

Maintenance request

Should there be indications of changes to parameters within the unit,

"maintenance request” will appear on the status line of the display. At the
time of their occurrence, changes of this kind will not affect the measuring
capability of the unit. But to guarantee long-term measuring capability,
remedial measures may need to be taken.

If the relay output of the unit has been configured correspondingly (see
also "Calibration” on page 5-11), signaling to the outside may also take
place.

Fault Defects in the hardware or changes in unit parameters which render the

unit unserviceable for measurement purposes will cause a fault message
to be generated. "Fault” then appears on the status line, provided the unit
is in measurement mode. The measured value flashes and remedial
measures must be taken without fail.

As with the maintenance request, there can be signaling to the outside via
the relay output (function 71). In addition the analog output can be linked
to the output current range which was set using function 77 (measured
value memory).

Other messages In addition to maintenance requests and fault messages, other important

messages are recorded in the logbook.

Table 6-2: Causes of fault messages

6.5.3 Other faults

Within an appropriate period of time according to the drift information
(see also "Technical data” on page 2-14) the unit should be calibrated at
the zero point (function 20) and at deflection (function 21) using the
corresponding test gases.
Attention should be given to clean gas preparation.
In most cases a greater zero point drift is an indication of matter or dust
particles being deposited in the analysis chamber (see "Cleaning”
on page 6-4).

Fault Possible cause and remedy

Large zero point drift towards +

Check gas preparation (filter), clean analysis
chamber (see "Cleaning” on page 6-4)

Large span drift Detector leaking, FID nozzle defective

Sensitivity markedly dependent on flow rate

Exhaust gas line restricted, for example by
condensed water
