WARNING
Toxic and/or corrosive gases
When measuring toxic or corrosive gases, it could occur that sample gas accumulates in
the analyzer because of leaks in the gas path.
To prevent the danger of poisoning or damage to parts of the analyzer, the analyzer or the
system must be purged with inert gas (e.g. nitrogen). The gas displaced by purging must be
collected using appropriate equipment and disposed of environmentally-friendly via an
exhaust line.

Analyzers in biogas plants
DANGER
Danger of poisoning
This device is designed to measure hydrogen sulfide and dihydrogen sulfide, H2S)!
Hydrogen sulfide is highly toxic even in small concentrations! The odor threshold for
hydrogen sulfide is very low at 0.02 vpm (20 vpb), but higher concentrations result in
numbing of the olfactory receptors in the nose so that the odor is no longer perceived.
Persons exposed to this gas in concentrations up to 100 vpm for several hours exhibit
symptoms of poisoning such as fatigue, headaches, lack of appetite, lack of concentration,
irritation of the mucous membranes of eyes and respiratory tract, and throat irritations.
Inhalation of H2S concentrations of 500 vpm longer than 30 minutes can cause fatal
poisoning. Concentrations above 1 000 vpm cause death within a few minutes,
concentrations above 5 000 vpm cause death within a few seconds!
When using this device in plant where there may be high concentrations of H2S and you
therefore need to take following continual precautions to prevent the effects of poisoning:
• Connect the gas outlet of the analyzer to a gas exhaust unit so that no gas can escape
into the environment!
• Before you begin maintenance on the analyzer, make sure that the H2S concentration in
the analyzer is close to 0 vpm. Before beginning work, always flush the gas path of the
analyzer and the gas sampler with ambient air or nitrogen for a duration of about 10
minutes .
• Check for leaks in the analyzer at regular intervals!
DANGER
Danger of explosion
This device is used in biogas plants, among other places. When it is used in biogas plants,
you should expect that the sample gas will contain methane, which forms explosive
mixtures with oxygen or air in certain concentrations. These conditions are possible with
certain operating states of the plant.
• To avoid the danger of an explosion, it is essential to install a flame arrester upstream of
the analyzer in the sample gas feed line of biogas plants.

Special versions
The BA 5000 with 2 IR components without pump is also available with two separate gas
paths. This allows the measurement of two measuring points as used e.g. for the NOx
measurement before and after the NOx converter.
The BA 5000 gas analyzer can be used in emission measuring systems and for
process and safety monitoring.
TÜV-approved versions of the BA 5000 are available for measurement of CO, NO, SO2,
and O2 according to 13. BlmSchV, 27. BImSchV, 30. BImSchV (N2O), and TA Luft.
Smallest TÜV-approved and permitted measuring ranges:
● 1- and 2-component analyzer
– CO: 0 to 150 mg/m3
– NO: 0 to 100 mg/m3
– SO2: 0 to 400 mg/m3
● 3-component analyzer
– CO: 0 to 250 mg/m3
– NO: 0 to 400 mg/m3
– SO2: 0 to 400 mg/m3
All larger measuring ranges are also approved. Furthermore, all TÜV-approved versions of
the BA 5000 comply with the requirements of EN 14956 and QAL 1 according to
EN 14181. Conformity of the analyzers with both standards is TÜV-certified. Determination
of the drift in measured value according to EN 14181 (QAL 3) can be carried out manually or
also with a PC using the SIPROM GA maintenance and servicing software. In addition, it is
possible with emission evaluation computers from selected manufacturers to download the
drift data via the analyzer's serial interface and to automatically record and process it in an
evaluation computer.
The analyzers of the BA-7MB2355, BA-7MB2357 and BA-7MB2358 series are
suitability-tested in accordance with EN 15267 (emission measurements).
Version with faster response time:
There is no connection between the two condensation traps, so that the complete sample
gas flow passes through the detector (only 1/3 of the flow in the normal version of the
analyzers), i.e. the response time is 2/3 faster. The functions of all other components remain
unchanged.
Version with chopper section purging:
This version consumes approx. 100 ml/min of purging gas; you must set an inlet pressure of
300 kPa (3 bar).

Operating principle of infrared measurement
27
Description
3.3 Function
This measuring principle is based on the molecule-specific absorption of bands of infrared
radiation, which in turn is based on the "single-beam procedure".
A radiation source (7) operating at 600 °C (1111 °F) emits infrared radiation, which is then
modulated by a chopper (5) at 8 1/3 Hz.
The infrared radiation passes through the analyzer chamber (4), into which sample gas is
flowing, and its intensity is weakened as a function of the concentration of the measured
component.
The receiver chamber (detector) - set up as a two- or three-layer detector - is filled with the
component to be measured. The first detector layer (11) primarily absorbs energy from the
central sections of the sample gas IR bands. Energy from the peripheral sections of the
bands is absorbed by the second (2) and third (12) detector layers. The microflow sensor
generates a pneumatic connection between the upper layer and the lower layers. Negative
feedback from the upper and lower layers leads to an overall narrowing of the spectral
sensitivity band. The volume of the third layer and, therefore, the absorption of the bands,
can be varied using a slide (10), thereby increasing the selectivity of each individual
measurement.
The rotating chopper (5) generates a pulsating flow in the receiver chamber that the
microflow sensor (3) converts into an electrical signal. The microflow sensor consists of two
nickel-plated grids heated to approximately 120 ºC (248 °F), which, along with two
supplementary resistors, form a Wheatstone bridge. The pulsating flow together with the
dense arrangement of the nickel grids causes a change in resistance. This leads to an offset
in the bridge which is proportional to the concentration of sample gas.
Note
Contamination of the analyzer chambers
The sample gases must be fed into the analyzers free of dust. Condensation should also be
prevented in the analyzer chambers Therefore, the use of gas modified for the measuring
task is necessary in most application cases.
Furthermore, the ambient air of the sensor must not have large concentrations of the
components to be measured.

Operating principle of the electrochemical O2 sensor
This oxygen sensor operates according to the principle of a fuel cell. The oxygen is
converted at the boundary layer between the cathode and electrolyte. An electron emission
current flows between the lead anode and cathode and via a resistor, where a measured
voltage is present. This measured voltage is proportional to the concentration of oxygen in
the sample gas.
The acidic electrolyte used is less influenced by interference influences (particularly CO2,
CO, H2, and CH4) than other sensor types.

Description
3.3 Function
Paramagnetic oxygen measurement
Figure 3-6
Operating principle of the paramagnetic O2 sensor
In contrast to other gases, oxygen is highly paramagnetic. This property is used as the basis
for this method of measurement.
Two permanent magnets generate an inhomogeneous magnetic field in the measuring cell. If
oxygen molecules flow into the measuring cell (1), they are drawn into the magnetic field.
This results in the two diamagnetic hollow spheres (2) being displaced out of the magnetic
field. This rotary motion is recorded optically, and serves as the input variable for control of a
compensation flow. This generates a torque opposite to the rotary motion around the two
hollow spheres by means of a wire loop (3). The compensation current is proportional to the
concentration of oxygen.
The calibration point is calibrated using the AUTOCAL function by connecting oxygen
(analogous to calibration of the electrochemical O2 sensor). In order to comply with the
technical data, the zero point of the paramagnetic measuring cell must be calibrated with
nitrogen weekly in the case of all measuring ranges < 5% or every two months in the case of
all larger measuring ranges.

Description
3.3 Function
Electrochemical hydrogen sulfide measurement
Figure 3-7
Operating principle of H2S sensor
The hydrogen sulfide (H2S) enters through the diffusion barrier (gas diaphragm) into the
sensor and is oxidized at the working electrode. A reaction in the form of a reduction of
atmospheric oxygen takes place on the counter electrode. The transfer of electrons can be
tapped on the connector pins as a current which is directly proportional to the gas
concentration.
The zero point is automatically recalibrated by the AUTOCAL function when connecting e.g.
nitrogen or air.
Automatic calibration of IR components with air (AUTOCAL)
Figure 3-8
Calibration
The BA 5000 can be calibrated using, for example, ambient air. During this process
(between 1 and 24 hours (adjustable), 0 = no AUTOCAL), the analyzer chamber is purged
with air. The detector then generates the largest signal U0 (no pre-absorption in the analyzer
chamber). This signal is used as the reference signal for zero point calibration. The signal U0
also serves as the initial value for calculating the full-scale value.
BA 5000
01/2015, BE555000
31
Description
3.3 Function
As the concentration of the measured component increases, so too does absorption in the
analyzer chamber. As a result of this preabsorption, the detectable radiation energy in the
detector decreases, and thus also the signal voltage. For the single-beam procedure of the
BA 5000, the mathematical relationship between the concentration of the measured
component and the measured voltage can be approximately expressed as the following
exponential function:
U = U0 ⋅ e-kc with the following parameters:
● c Concentration
● k Unit-specific constant
● U0 Basic signal with zero gas (sample gas without measured component)
● U Detector signal
Changes in the radiation power, contamination of the analyzer chamber, or aging of the
detector components have the same effect on both U0 and U, and result in the following:
U’ = U’0 ⋅ e-kc
Apart from being dependent on concentration c, the measured voltage thus changes
continuously as the IR source ages, or with persistent contamination.
Each AUTOCAL thus tracks the total characteristic according to the currently valid value,
thereby also compensating temperature and pressure influences.
The influences of contamination and aging, as mentioned above, will have a negligible
influence on the measurement as long as U’ remains within a certain tolerance range
monitored by the unit. The tolerance range between two or more AUTOCAL procedures can
be individually parameterized on the BA 5000 and a warning output in the event of
deviations. A fault message is output when the value falls below the original factory setting of
U0 < 50% U. In most cases, this is due to the analyzer chamber being contaminated.
The units can be set to automatically calibrate the zero point every 1 to 24 hours, using
ambient air or nitrogen. The calibration point for the IR-sensitive components is calculated
mathematically from the newly determined U’0 and the device-specific parameters stored as
default values. It is recommendable to check the calibration point once a year using a
calibration gas. For details on TÜV measurements, see Table "Calibration intervals (TÜV
versions)" in section Infrared detector (Page 36).
If an electrochemical O2 sensor is installed, it is recommendable to use air for the AUTOCAL.
In addition to calibration of the zero point of the IR-sensitive components, automatic
calibration of the calibration point of the electrochemical O2 sensor is carried out
simultaneously. The characteristic of the O2 sensor is sufficiently stable following the singlepoint calibration such that the zero point of the electrochemical O2 sensor need only be
checked once a year by connecting nitrogen.

PROFIBUS DP/PA
PROFIBUS DP/PA is the leading fieldbus on the market. All Bühler gas analyzers with an
optional – also retrofittable – plug-in card are Profibus-compatible and comply with the
binding "Device profile for analyzers" defined by the PNO (PROFIBUS International). Central
access to the system analyzers is possible with the SIMATIC PDM software tool.
"Fieldbus" is the name of a digital communication system with which distributed field devices
of a system are linked to each other over a single cable and are simultaneously connected to
programmable controllers or a process control system.
The PROFIBUS-DP version is widespread in factory automation due to its high transmission
speed per device, while PROFIBUS-PA takes the required properties of process engineering
into account, such as use in hazardous areas.
The benefit is the considerable savings potential in all areas of the system, covering project
planning and commissioning, operation and maintenance, up to subsequent system
extensions.
Operation of the gas analyzers from a control system or a separate PC is possible with the
SIMATIC PDM software tool (Process Device Manager). This software executes under
Windows XP/Windows 2000 and can also be integrated in the SIMATIC PCS 7 process
control system. With this, the integration of the devices in the system as well as the complex
parameter structure of the analyzers can be clearly illustrated. Operating becomes simply a
matter of "clicking".
PROFIBUS International (PNO) is an independent institution and represents the interests of
many manufacturers and users. This organization offers services such as consulting, training
and device certification, and understands its primary job as the further development,
standardization and promotion of PROFIBUS technology. The binding functionality definition
for a device class in the form of a profile is the condition for standardized device behavior
from various manufacturers, the so-called interoperability. The binding profile for analyzers
was defined at the end of 1999. With this, the interaction of all PROFIBUS-compatible
devices of a system is guaranteed.
In this profile, the functionalities of the analyzers are defined in a block model: for example,
the physical block describes the measuring procedure, analyzer and manufacturer name,
serial number and the operating state (operation, maintenance). Different functional blocks
contain the execution of certain functions, such as measured value and alarm processing.
The transducer blocks describe the function of the actual measuring process, as well as its
control, e.g. the pre-processing of a measured value, correction of cross-interferences,
characteristics, measuring ranges, as well as switching and control processes. The data
transmission between the bus participants is defined in protocols.
A distinction is made between cyclic and acyclic services. Time-critical data, such as
measured values and status, are transmitted with cyclic services. The acyclic services allow
device parameters to be queried or changed during operation.

operation in potentially explosive environments. The FM/CSA and ATEX approvals do not
apply to these versions.
WARNING
Insufficient ventilation
The device may overheat or start burning in the case of insufficient ventilation.
• Ensure sufficient ventilation between the devices when installing in control cabinets. The
heat sinks at the rear must remain free for air circulation.
• Make sure during operation that the permissible ambient temperature range is always
observed (see General technical data (Page 33)).
NOTICE
Incorrect mounting
The device can be damaged, destroyed, or its functionality impaired through improper
mounting.
• Before installing ensure there is no visible damage to the device.
• Make sure that process connectors are clean, and suitable gaskets and glands are
used.
• Mount the device using suitable tools. Refer to the information in Chapter "Technical

Analyzers in biogas plants
DANGER
Explosion hazard
This device is used in biogas plants, among other places. When it is used in biogas plants,
you should expect that the sample gas will contain methane, which forms explosive
mixtures with oxygen or air in certain concentrations. These conditions are possible with
certain operating states of the plant.
• To avoid the danger of an explosion, it is essential to install a flame arrester upstream of
the analyzer in the sample gas feed line of biogas plants.

5.2 Gas connections and internal gas path
5.2.1
Gas connections
Sample gas line
A pipe with a outer diameter of 6 mm or 1/4" is present as the gas connection. The materials
used in the gas path must be suitable for the respective measurement.
If you wish to exit the sample gas into a collective exhaust line, observe the following points:
● The exhaust line must be free of rapid changes in pressure. If this is not possible, either a
separate exhaust line must be installed, or a damping vessel with a capacity > >1 l must
be installed between the analyzer and the exhaust line.
● The exhaust gas line must always be routed with a falling gradient away from the device
since moisture can condense in it.
Path for AUTOCAL/zero gas
The gases for the AUTOCAL calibration must be sucked in via a fine filter. The amount of the
measured gas component must be negligibly small in the AUTOCAL gas (zero gas). In
particular when carrying out an AUTOCAL for CO2 ranges <1%, the air must be routed via a
CO2 absorber (e.g. soda lime).
Path for chopper section purging
With CO2 ranges < 0.1%, the chopper section is purged with clean nitrogen or CO2-free
synthetic air at an inlet pressure of 300 ... 350 kPa (43 ... 51 psi).
Path for pressure sensor
The internal atmospheric pressure sensor is routed via a hose to connection 6. It is therefore
possible to connect the pressure sensor (e.g. when using analyzer cabinets or houses) such
that it is guaranteed that only changes in atmospheric pressure are recorded.
5.2.2
Gas preparation
The sample gas must be sufficiently conditioned to prevent contamination of the parts
through which it flows. The BA 5000 is usually preceded by the following elements:
● Gas sampling device with filter
● Sample gas cooler
● Analysis filter (approx. 1-2 μm)
● External gas suction pump (with sample gas lines >20 m/65 1/2 ft)

● The analog outputs are floating, but have a common negative pole.
● As a measure to suppress sparking across the relay contacts (e.g. limit relays), RC
elements must be connected as shown in the following figure. Note that the RC element
results in a drop-out delay for an inductive component (e.g. solenoid valve). The RC
element should be sized according to the following rule of thumb:
– R = RL/2; C = 4L/R2L,
where R = 100 Ω and C = 200 nF are sufficient.
– You must use a non-polarized capacitor for the RC element.

Use in biogas plants
DANGER
Danger of poisoning
This device is designed to measure hydrogen sulfide and dihydrogen sulfide, H2S)!
Hydrogen sulfide is highly toxic even in small concentrations! The odor threshold for
hydrogen sulfide is very low at 0.02 vpm (20 vpb), but higher concentrations result in
numbing of the olfactory receptors in the nose so that the odor is no longer perceived.
Persons exposed to this gas in concentrations up to 100 vpm for several hours exhibit
symptoms of poisoning such as fatigue, headaches, lack of appetite, lack of concentration,
irritation of the mucous membranes of eyes and respiratory tract, and throat irritations.
Inhalation of H2S concentrations of 500 vpm longer than 30 minutes can cause fatal
poisoning. Concentrations above 1 000 vpm cause death within a few minutes,
concentrations above 5 000 vpm cause death within a few seconds!
When using this device in plant where there may be high concentrations of H2S and you
therefore need to take following continual precautions to prevent the effects of poisoning:
• Connect the gas outlet of the analyzer to a gas exhaust unit so that no gas can escape
into the environment!
• Before you begin maintenance on the analyzer, make sure that the H2S concentration in
the analyzer is close to 0 vpm. Before beginning work, always flush the gas path of the
analyzer and the gas sampler with ambient air or nitrogen for a duration of about 10
minutes .
• Check for leaks in the analyzer at regular intervals!
DANGER

6.3.1
Leaks in the gas paths
Checking for leaks is most easily performed by connecting a U-tube manometer to the
sample gas inlet. You can check for leaks as follows:
1. Block the sample gas outlet
2. Create an overpressure of around 150 hPa (rel.) at the sample gas inlet.
3. Wait for about 60 seconds for the temperature of the incoming gas to be compensated.
4. Read the pressure on the manometer and note it
5. Wait a further 15 minutes and note the pressure again after this period.
6. Compare the two pressure values.
The sample gas path is sufficiently tight when the pressure has changed by no more than
2 hPa (2 mbar) over 15 minutes.
For analyzers with H2S sensors
:The sample gas path is sufficiently tight when the pressure has changed by no more than
5 hPa (5 mbar) over 15 minutes.

● The analyzer is set to the correct operating voltage
● All gas preparation elements are connected and ready for operation, and have been

● All required connections to and from the analyzer have been established
Following successful checking, connect the analyzer to the power supply and switch it on.
Wait for the warm-up phase to elapse (see Warm-up phase (Page 95)).
6.4.1
AUTOCAL
The analyzer carries out an automatic calibration with the connected medium during the
warm-up phase following switching-on. This AUTOCAL adjusts the zero point and sensitivity
of the IR channels. If an O2 sensor is present, its sensitivity is additionally calibrated using
the ambient air (20.95% O2).
Note
Analyzers with H2S sensor
The hydrogen sulfide sensor is not calibrated during the course of this first AUTOCAL. The
zero point of the H2S sensor is only calibrated starting from the second AUTOCAL of the
analyzer.
Note
Analyzers without electrochemical O2 sensor
In the case of analyzers without an electrochemical O2 sensor, the AUTOCAL can be carried
out with nitrogen, but in the case of analyzers with an electrochemical O2 sensor, it is
essential to use air. The correct medium is selected depending on the used configuration
(gas connections) and cannot be parameterized using the software.
Note
Analyzers with paramagnetic O2 sensor
In the case of analyzers with a paramagnetic O2 sensor, the input menu can be used to
select whether the AUTOCAL is to be carried out with air or N2, and thus whether the
sensitivity (20.95 % O2) or the zero point of the sensor is calibrated.

Note
Analyzers with small CO2 measuring ranges
In the case of analyzers with small CO2 measuring ranges, it is necessary to connect the
chopper section purging. This can be carried out with nitrogen or synthetic air with an inlet
pressure of 300 ... 350 kPa (3 ... 3.5 bar). The purging equipment must be connected at least
30 min before switching on in order to guarantee good purging of the analyzer unit.
You can manually trigger an AUTOCAL during operation by pressing the CAL key or also
activate an AUTOCAL via the binary input or the communication interface. The analyzer can
also execute an AUTOCAL cyclically, i.e. at regular intervals.
Duration
The duration of the AUTOCAL depends on various factors. It is
● Approx. 12 minutes for analyzers with H2S sensor
● Approx. 3 minutes for analyzers with O2S sensor
● Approx. 2 minutes for analyzers which only measure IR components
This is made up as follows:
● Twice the set purge time (see Calibration: AUTOCAL/drift values: Purge time (Page 125))
● Duration of the internal electronic adjustment (corresponds to two and a half times the
time constant T90 within (see Parameters: Time constants (Page 132)).
Note
An AUTOCAL is carried out twice during the warm-up phase; the first time approx. 5 min
after switching on, and the second time after approx. 30 min.

Initial calibration
Initial calibration with calibration gas
Following installation of the analyzer, we recommend a calibration using calibration gas (see
Calibration (Page 112)). The calibration should be carried out with a gas containing a
sufficient concentration of the measured component (between 70 and 100% of the full-scale
value in nitrogen or synthetic air).
Note
The calibration gas is connected via the sample gas path.
The analyzer must have been in operation for at least 30 minutes before commencing with
measurements since a good stability of the analyzer unit is only guaranteed after this time
(99% value).
Make sure that the gas flow is between 1.2 and 2.0 l/min.
Any noise which may occur can be suppressed by adjusting various time constants (see
Parameters: Time constants (Page 132)).
The calibration should be repeated every six to twelve months depending on the ambient
conditions.

Warm-up phase
Figure 7-4
Warm-up phase, measuring mode, and input mode
Immediately following switching-on, the BA 5000 tests the
display elements. During this test, all elements light up
simultaneously for approx. five seconds.
The adjacent display subsequently appears with the remaining
warm-up period which is counted down in seconds to 00:00
(minutes:seconds).
The analyzer initially carries out an AUTOCAL during the
warm-up phase. The flow of AUTOCAL gas (nitrogen or air) is
displayed in the bottom line, and the remaining time is shown
in the line above this. This calibration cannot be interrupted.
Following the calibration, the analyzer switches to purging with
sample gas. At the end of the purging phase, the analyzer
switches to measuring mode; however, full measuring accuracy is only reached after approx. 30 min if a further AUTOCAL
has been automatically carried out by the analyzer. The warmup phase is then finished.

Measuring mode
The measured components are output on the display together
with their values and the units in mg/m3, vpm or volume percent. With a change in the analyzer status, the corresponding
letter appears in the last two columns ("P" in the example; see
also Display and operator panel (Page 91)). The analyzer remains in measuring mode until an AUTOCAL (automatic, remote-controlled or manual) is carried out or until you manually
switch the analyzer to input mode.
If analyzers are installed in closed analysis cabinets, opening
the cabinet door may result in brief drifting of the measured
values. This is a result of the temperature exchange which then
takes place.
If '*****" is displayed in measuring mode without a fault being
present, this means:
• Concentration in sample gas more than 5% higher than the
largest measuring range
• Signal saturation resulting from excessively high sample gas
concentrations

CAUTION
Unauthorized operation
The analyzer must only be calibrated and/or parameterized by trained specialists with
adherence to these operating instructions.
Once you have selected input mode, the first menu to appear is
the main menu which displays four menu items. You can use
these to select the individual input functions of the BA 5000:
Analyzer status
With these functions you can call submenus which provide information on the analyzer
status, e.g. entries in the logbook, diagnostics data, and factory data (see Analyzer status
(Page 103) for menu structure).
Calibration
With these functions you can calibrate the zero and sensitivity of the analyzer using
calibration gas (see Calibration (Page 112) for menu structure).
Parameters
With these functions you can match the analyzer functions to your specific application, e.g.
by entering limits, measuring ranges, and time constants (see Parameters (Page 126) for
menu structure).
Configuration
With these functions you can define the assignments of the analyzer interfaces etc., e.g. the
assignments of relays and current outputs (see Configuration (Page 134) for menu
structure).

Code levels
The BA 5000 is provided with two code levels to protect against unauthorized or
unintentional inputs. As soon as you call a function protected by a code for the first time, you
will be requested to enter the three-digit code number.
Note
You should change the factory-set codes once you have become acquainted with operation
of the BA 5000 (see section Configuration: Special functions: Changing the
codes/language (Page 145)).
The lowest code level (level 1) is factory-set to "111", and the higher level (level 2) to "222".
The following are protected by code level 1:
● The dialogs "Logbook/faults" and "Maintenance requests" in the menu "Analyzer status",
submenu "Status",
● the menu "Calibration" ,
and
● the menu "Parameters".
The following is protected by code level 2:
● The menu "Configuration".
Note
If the analyzer requests you to enter code level 1, you can enter level 2 instead. Level 1 is
then enabled simultaneously. Level 1 is automatically enabled as soon as the higher code
level 2 has been enabled.
Following input of a code, inputs are possible until the analyzer is recoded.
Note
In order to code the analyzer again when the input procedures have been finished (to protect
against unauthorized and unintentional interventions), press the <MEAS> key in measuring
mode.

The initial display of the "Parameters" submenu appears.
Press the <ENTER> again to call the "Measuring ranges" submenu.
Now select components 1 to 4 for which the subsequently set
ranges are to apply. Up to four components can be present.
If your analyzer is configured accordingly, you can select another component by pressing one of the
<↑> or <↓> keys. In this example, this is component 3.
Press the <ENTER> key. The analyzer switches one level lower
and now offers functions applicable to the selected measuring
range.
The adjacent display appears with the functions selectable for
this range (MR). You can select these by pressing the <↑> or
<↓> key, and branch to the selected function by pressing the
<ENTER> key.
In this example, the adjacent display appears following selection of the function "Switch ranges CO".
The first line contains the heading, the second line the parameter and its value to be changed; the cursor is positioned in this
line. Only supplementary information is
present in lines 3 and 4.
To switch over the measuring range, proceed as follows:
• Press the <ENTER> key.
The cursor jumps to the measuring range number which you
can change using one of the <↑> and <↓> keys.

You cannot carry out any further settings here. To do so, you
must leave the menu display again. This is possible:
• By pressing the <ESC> key. You then return by one step in
the menu sequence
• by pressing the <MEAS> key. You then have the following
possibilities:
– To process the previous menu item further using
<ENTER>
– or return to measuring mode using <↑> or <→> and
subsequently <ENTER>, where all modifications are
imported which you have made since the last decoding
operation,
– or return to measuring mode using <↓> and <ENTER>
without importing the modifications..
Once you have carried out the above sequence on the analyzer, you are already acquainted
with the important points for operation of the BA 5000.
7.4.3.3
The ESC key
You can trigger two different functions by pressing the <ESC> key:
● Firstly, you can cancel a commenced procedure, e.g.:
– The input of a number
– A calibration procedure with calibration gas
– Any function if a fault occurs, e.g. if the flow of sample gas to the analyzer is missing.
● Secondly, you can use the <ESC> key to move to the next higher level in menu structure
("scroll back"). This procedure is the opposite to selection of a submenu using the
<ENTER> key ("scroll forwards"). If you repeatedly press the <ESC> key, you return back
to the main menu step-by-step. If you press the <ESC> key again in the main menu, the
analyzer switches over from input to measuring mode. All inputs are imported at the
same time. However, you will not be asked to confirm the inputs.

Operation
7.4 Operating modes
An example will clarify this:
The analyzer is in measuring mode and is uncoded.
Switch from measuring mode to input mode using
<ENTER>, select the menu item "Parameters" using the
<↑> or <↓> key, and press <ENTER> to confirm.
In this manner, you enter the first submenu.
Now press <ESC> and then
<ENTER> again. You have returned by one level and then
moved forwards by one level again; you are therefore in the
same menu again.
Press the <ESC> key twice, you are back in measuring
mode again.
7.4.3.4
The CAL key
If the analyzer is in measuring mode, pressing the <CAL> key triggers a single, automatic
calibration with ambient air or nitrogen (AUTOCAL).
The <CAL> key cannot be used during the warm-up phase.
If the flow is too low during a zero calibration triggered by pressing the key, the analyzer
remains in this status until either the flow is sufficient or the zero calibration is aborted by
pressing the <ESC> key.
In addition to the <CAL> key, an AUTOCAL can also be triggered via the binary input. The
binary input has priority over the key.
7.4.3.5
The PUMP key
If the analyzer is equipped with an internal sample gas pump, this can be switched on and
off using the <PUMP> key. If the pump is switched off while the analyzer is in input mode, it
is also switched on again by pressing the <MEAS> key if parameterized accordingly (see
Configuration: Inputs/outputs/pump: Pump at CAL/MEAS (Page 144)).
In addition to use of the <PUMP> key, the pump can also be switched on and off via the
binary input. The binary input has priority over the key.

BA 5000 via further submenu items.
In this example, the status of the O2 sensor is shown in the last
line. If the analyzer is equipped with software for operating an
H2S sensor, the text 'Probe status' is shown in the last line with
the following options:
• Only H2S sensor:
The analyzer calls this function directly.
• H2S and O2 sensors:
You will be requested to select the associated sensor.
8.1.1.1
Analyzer status: Status: Logbook/faults
This dialog displays the contents of a logbook. This contains all recorded faults. Each type of fault only appears
once in the logbook and is output in alphanumeric text (an
overview of the possible faults can be found in section
Faults (Page 183)).
Viewing the logbook is protected by code level 1.
Following access to the logbook you can:
• Display all recorded faults in succession using the <→>
key
• Delete the currently displayed fault message using the
<ENTER> key.
If further faults are present, these appear in succession.
You should delete all fault messages whose causes
have been eliminated.
Note
By deleting the fault message you do not eliminate the
cause of the fault (see section Faults (Page 183)).
A corresponding text is output when all stored faults have
been displayed. Terminate display of the logbook using the
<→> key.
Note
If the analyzer is in measuring mode, you can recognize
the occurrence of a fault in that an "F" appears at the right
edge. A "! at the right edge signals that a fault has been
logged which is no longer present.

Analyzer status: Status: Maintenance request
This dialog indicates the logged maintenance requests. A
maintenance request is set if the values of certain parameters
have reached defined limits, but the analyzer is still able to
measure (e.g. AUTOCAL deviation or O2 sensor status; see
also section Analyzer status: Status: O2 sensor status
(Page 106)). A corresponding message is output in alphanumeric text.
Access is protected by code level 1.
Following access to the maintenance request list you can:
• Display all recorded faults in succession using the <→> key
• Delete the currently displayed fault message using the
<ENTER> key. If present, the next maintenance request is
then displayed. You should delete all maintenance requests
whose causes have been eliminated.
Note
If the analyzer is in measuring mode, you can recognize the
occurrence of a maintenance request in that an "M" appears at
the right edge.
8.1.1.3
Analyzer status: Status: AUTOCAL deviation
This dialog indicates the deviation in setpoint between several
AUTOCAL procedures. The parameters have the following
meanings:
• The text in the two top lines provides information on the
number of AUTOCAL procedures which have been carried
out since the reference value for AUTOCAL was last set
(see section Configuration: Special functions: AUTOCAL
deviation (Page 146)).
• Deviation is the measured deviation of the actual value from
the reference value, displayed in % of the set measuring
range (with autoranging, range 1 is assumed). This
deviation must not be above the set maximum value.
• Max. allowed is the maximum permissible value for the
deviation. Refer to section Configuration: Special functions:
AUTOCAL deviation (Page 146) for setting the maximum
value.
This function is specific to the component.

Functions
8.1 Analyzer status
8.1.1.4
Analyzer status: Status: O2 sensor status
The probe voltage of the O2 sensor is reduced during use due
to its aging process. Therefore the probe voltage is measured
with each AUTOCAL. A warning (maintenance request) is output if the value drops below 6.0 mV. The oxygen sensor should
therefore be replaced when this value is reached. An exact
measurement is no longer possible if the probe voltage falls
below the minimum value of 5.0 mV (fault message "Sensitivity
of O2 sensor too low").
• The reading (actual value) is the probe voltage measured
on the sensor during the last AUTOCAL.
• The warning (maintenance request) and fault are the two
minimum values where a maintenance request or fault
message is output when fallen below.
8.1.1.5
Analyzer status: Status: H2S sensor status
The H2S sensor ages with increasing operating time, thereby
steadily decreasing its sensitivity. If a value below the minimum value for a warning is determined during calibration of the
sensitivity, the service life of the sensor has almost been
reached (maintenance request). If the sensitivity drops further
below the value for a fault, the fault message "Sensitivity of
H2S sensor too low" is output. The sensor must then be replaced.
• The reading (actual value) is the sensor sensitivity
measured during the last sensitivity calibration.
• The warning (maintenance request) and fault are the two
minimum values where a maintenance request or fault
message is output when fallen below.

Calibration: Infrared measuring range: Start with Range MR 1/2
The analyzer interrupts the current measurement if you call
one of these two dialogs. If the parameter 'With AUTOCAL'
• was set to OFF, the analyzer expects an immediate flow of
calibration gas;
• if the value is set to ON, an AUTOCAL is carried out prior to
the flow of gas.
The values of the setpoint and actual-value calibrations are
displayed in the first two lines.
If the analyzer recognizes a flow of calibration gas, the display
changes as shown. If the measured value in the second line
remains constant for more than approx. 10 s or does not
change significantly, press the <ENTER> key.
The analyzer then compares the setpoint and actual value
(measured value) of the calibration. If the deviation between
the values is within the tolerance, the adjacent message 'o.k.'
is output.
If the actual value deviates by more than approx. 20% from the
setpoint determined in the factory, the message 'not o.k.' appears instead (no calibration possible).

In this menu you can:
• Permit or cancel the switching over between measuring
ranges
• Set the full-scale values
• Define a hysteresis.
Note
Please note that the range parameters only refer to the measuring ranges at the analog
outputs (see section Configuration: Inputs/outputs/pump: Analog outputs (Page 137)). The
display always shows the complete, physically possible range.
8.3.1.1
Parameters: Measuring ranges: Switch ranges
In the second line of this dialog you can set the measuring
range 1 or 2 or permit autoranging (automatic switching over
between these two ranges).
The 'Actual range' parameter can have the following values:
• 1:
The analyzer is set to the smaller range (MR 1).
• 2:
The analyzer is set to the larger range (MR 2).
• 1/2:
The analyzer is set to the larger range (MR 2). The start-ofscale value of the analog output corresponds in this case to
the full-scale value of the smaller range (MR 1), the fullscale value of the analog output corresponds to that of the
larger range (MR 2).
The result is that the analog output of the analyzer has a
range with zero offset (e.g. 90 ... 100%).
• AR:
The analyzer switches over automatically from one range to
the other (AR = autoranging). Setting of the switchover
criteria is described in section Parameters: Measuring
ranges: Hysteresis (Page 129).

8.3.1.3
Parameters: Measuring ranges: Hysteresis
In the third and fourth lines of this dialog, you can set the value
at which the analyzer switches from one range to the other.
The values are specified in % of the full-scale value of range 1
(MR1) (see section Parameters: Measuring ranges: Setting
measuring ranges (Page 128)).
Note
The hysteresis is only active if the "Actual range" parameter
has been set to the value "AR" (autoranging) in the dialog
"Switch ranges"(Parameters: Measuring ranges: Switch ranges
(Page 127)).
The two switchover points should be as far apart as possible,
and the switchover point from MR1 to MR2 must be greater
than that from MR2 to MR1.
The following conditions have been assumed in the display:
• Your analyzer has two ranges:
– MR1 from 0 to 400 mg/m3
– MR2 from 0 to 2000 mg/m3.
• The hystereses are defined as:
– MR1->MR2 at 100%
– MR2->MR1 at 90%.
This means:
• If your analyzer is working in the smaller range (MR1), it
switches over to the larger range (MR2) when a value
greater than 400 mg/m3 SO2 is measured
• If your analyzer is working in the larger range (MR2), it
switches over to the smaller range (MR1) when a value less
than 360 mg/m3 SO2 is measured (=90% of 400 mg/m3).

Parameters: Time constants
You can use this function to set various time constants to suppress noise in the measured signal. During processing of the
measured signals, these time constants reduce the noise by
delaying the signal. The time constant "T90 within" is effective
within an adjustable interval whose threshold values are defined as a percentage of the smallest measuring range. The
time constant dampens small changes in signal (e.g. noise),
but becomes immediately ineffective if a fast change in signal
exceeds a threshold. If the threshold is exceeded, the signal is
dampened by the time constant "T90 outside" until it falls below
the threshold value again. "T90 within" then becomes effective
again.

The following values are possible for the time constants:
• T90 within: 0.1 to 99.9 (s)

8.5
Automatically executed functions
A protection and purging function is implemented by means of software since H2S
concentrations above the specified continuous concentration impair the functionality and
service life of the H2S probes (50 ppm and 5000 ppm).
In addition, a purging function is implemented for the 50 ppm H2S probe in order to allow an
intermittent measurement above the permissible continuous concentration.
These functions are executed automatically when certain operating states occur.
8.5.1
Probe protection function
Definition of probe protection function
A value 1.1 times the specified range can be considered as the maximum continuous
concentration. Although a measurement above such a concentration is still correct, the probe
is damaged by longer exposure. The maximum continuous concentration remains constant
even when changing the large measuring range. The maximum continuous concentration for
the 5000 vpm H2S probe is 5500 vpm.
The protection function is also implemented with the 50 vpm probe for compatibility reasons
even though its maximum continuous concentration is 12.5 vpm. The protection function is
executed above this value.
Execution of this function is the same for all probes. The function test is set during execution
of the protection function in order to signal that the displayed value is incorrect.
How the protection function works
The protection function is triggered if the continuous measured value of H2S is greater than
the maximum continuous concentration (110 % of full-scale value) in measuring mode for a
period of 3 seconds.
The following occurs when the protection function starts:
● The H2S measured value display is set to "*****"
● An "H" (H2S protection function running) is displayed in the measurement screen at the
right edge where the test letter "!" appears (fault no longer pending has been logged).
● The zero gas valve is opened
● The "Function control" status is set.
As long as the protection function is active, the zero gas valve remains open during the zero
gas purge time. The device then switches to purging of the sample gas path with sample
gas. This process is repeated if the maximum continuous concentration is exceeded within
the sample gas purge time.
This process is repeated up to 6 times. If the sample gas concentration is still too high after
the 6th repeat, the zero gas valve remains permanently open and the fault 28 "H2S probe
protection" is entered in the logbook.
BA 5000

157
Functions
8.5 Automatically executed functions
If the maximum continuous concentration is not exceeded again, the protection state is
terminated and the H2S measured value is displayed again. Furthermore, the function control
and the test letter "H" are deleted.
Return to measuring mode
An active protection function can be interrupted as follows:
● Automatic: The measured value in the sample gas purge time remains permanently
below the maximum continuous concentration prior to completion of the 6th repeat.
● Set the protection function to 'OFF' by changing the parameter in the limit display or via
ELAN
● Start a different state such as calibrate, AUTOCAL, etc.
● Acknowledgment of the fault "H2S probe protection" in the logbook
Sequence parameter
The zero gas purge time is twice the AUTOCAL purge time. The sample gas purge time is
equal to the AUTOCAL purge time. The AUTOCAL purge time is an adjustable parameter
whose setting is described in section Calibration: AUTOCAL/drift values: Purge time
(Page 125).
The protection function can be enabled and disabled using the menu item 'H2S probe
protection' (see section Parameters: Limits: H2S sensor protection (Page 131)). The function
is ON with the factory setting.
The device remains in measuring mode while the protection function is running. You can
read out via ELAN or PROFIBUS whether the protection function of the analyzer is being
processed, and in which step.

Probe purging function
Hydrogen sulfide measurement: Purging function of 50 vpm probe
Hydrogen sulfide (H2S) is a corrosive gas, especially in wet condition and in combination with
other gases. A selectable protection function has been implemented (see section Probe
protection function (Page 157)) since H2S concentrations above the permissible continuous
concentration impair the functionality and service life of the H2S probes. A purging function
has additionally been integrated for the 50 vpm probe, enabling a discontinuous
measurement above its permissible continuous concentration.
The permissible continuous concentration is 12.5 vpm. Although a measurement above such
a concentration is still correct, the probe is damaged after a certain period. This period can
be set in accordance with the experience gained using the sensor between 10 und
20 minutes using the AUTOCAL purge time (the purging duration corresponds to twice the
AUTOCAL purge time). For this reason measurements above a concentration of 12.5 vpm
must be carried out discontinuously and alternately with purging gas. The probe can be used
for a measurement again following a purging time of equal duration with air.
The function test is set during execution of the purging function in order to signal that the
displayed value is incorrect.
How the purging function works
The purging function is triggered if the continuous measured value of H2S is greater than the
permissible continuous concentration (12.5 vpm) in measuring mode for a period equal to
the duration of the zero gas purge time.
Following triggering of the purging function:
● The last measured values of all components are 'frozen' if the 'Analog outputs with
FCTRL' parameter has been set to 'Hold', or the current measured values are still
displayed for all other settings.
● A "V" (H2S purging function running) is displayed flashing in the measurement screen at
the right edge where the test letter "!" appears (fault logged, no longer pending).
● The zero gas valve is opened.
● The "Function control" status is set.
As long as the purging function is active, the zero gas valve remains open during the zero
gas purge time. The device then switches to the sample gas path. The status 'Function
control (FCTRL)' remains set and the test letter "V" flashes during the zero gas purge time
and the subsequent pre-purging phase. This signals that the displayed measured values are
incorrect. The status 'Function control' and the test letter are deleted following the prepurging phase, and the current measured values displayed again. Monitoring of the H2S
threshold for the permissible continuous concentration is already re-activated during the prepurging phase.

Return to measuring mode
An active purging function can be exited or interrupted if:
● The H2S measured value remains permanently below the threshold for the permissible
continuous concentration during the pre-purging phase
● The probe protection function is triggered
● A different device status is started such as calibration, AUTOCAL, etc.
Sequence parameter
The zero gas purge time is twice the AUTOCAL purge time. The pre-purging phase is equal
to the AUTOCAL purge time. The AUTOCAL purge time is an adjustable parameter whose
setting is described in section Calibration: AUTOCAL/drift values: Purge time (Page 125).
The device remains in measuring mode while the protection function is running. You can
read out via ELAN or PROFIBUS whether the protection function of the analyzer is being
processed, and in which step.

H2S sensor with 'large' measuring range
This section reflects the experiences gained with operation of a sensor for a measuring
range of 0 to 5000 vpm H2S.
Packaging
The transport packaging is not gas-tight. To prevent drying-out of the sensor and the
possibility of malfunctions, the sensor may only be stored for a period up to 3 months.
Storage and transport
Storage at an excessively high humidity (tropics, several months) results in swelling of the
electrolyte which could damage the electrolyte vessel.
As a rule of thumb: The sensor can be used for 12 months following manufacture and
storage.
Battery
The BA 5000 must be operated continuously since the H2S sensor has its own battery whose
voltage is retained through operation of the BA 5000. This battery has a
(theoretical) service life of approx. 4 years.
With the analyzer switched off, the power supply to the sensor is from its own battery. The
resulting discharging of the battery impairs the sensor functionality and results in zero and
span drifts as well as increased signal noise Once a battery has been discharged, it requires
a charging time of up to two days before the sensor works correctly again.
Details on restart following voltage drop
● Brief outage - charging time of several hours
● Outage of two hours or longer - charging time of two days or longer
Materials used in the sample gas path
As a result of its polarity and good solubility in water, H2S accumulates on various materials.
These adsorption and desorption effects lead to increases in the response times. Therefore,
the inlet piping for the sample gas should be made of PTFE. Other materials should only be
used for short gas lines.

Application note
9.1 H2S sensor with 'large' measuring range
Environmental conditions
● The ambient temperature at the installation location must not exceed 40 °C (104 °F)
● The maximum storage temperature for the H2S sensor is 55 °C (131 °F)
● The variation in output signal is 15 vpm, and the detection limit is 30 vpm
● The sensor service life is approx. 12 months
● The permissible ambient pressure is 750 ... 1200 hPa (11 ... 17 psi)
● The display delay (T90 time) is <80 s with a sample gas flow of approx. 1 ... 1.2 l/min
● The repeatability is < 4% referred to the full-scale value
Ambient temperature
The influence of ambient temperature on the sensor is 3%/10 °C, referred to the full-scale
value of 5000 vpm. This corresponds to a value of 150 vpm/10 °C.
With measuring ranges below 1500 vpm, it is therefore necessary to select the installation
location such that temperature stability is guaranteed. If this is not possible, a system cabinet
with cooling or heating components must be provided to enable correct operation.
We additionally recommend carrying out an AUTOCAL with ambient air every 3 hours. This
measure can compensate additional temperature variations e.g. between day and night.
AUTOCAL / zero
An AUTOCAL of the zero point should be carried out every 60 minutes. On the one hand,
this AUTOCAL is used to protect the sensor, but it also compensates the influence of
temperature variations during the day.
Sample switchover between raw gas / pure gas
The sensor only functions correctly if the values at the measuring point do not greatly differ
from one another. We cannot recommend switching over between measuring points on the
raw gas side (high H2S concentration) and the pure gas side (low H2S concentration), since
the difference between the H2S concentrations of the two gas flows is too large for a reliable
measurement.
Pressure influence
Abrupt changes in pressure must be avoided. Although the sensor compensates pressure
variations within approx. 20 seconds, it cannot handle pressure surges which may occur
when switching over between samples.

BA 5000
01/2015, BE555000
Application note
9.1 H2S sensor with 'large' measuring range
Flow
The sample gas should flow continuously and at a constant rate, also during an AUTOCAL.
While an AUTOCAL is being carried out, the sample gas flow must be diverted by means of
appropriate valve switching.
Reason: H2S is highly soluble in water and accumulates in the condensate. This
accumulation increases as the sample gas pressure increases. This effect can result in
significant delays in the response time.
Influencing variables
The hydrogen sulfide sensor cannot be used if the associated gas contains the following
components:
● Compounds containing chlorine
● Compounds containing fluorine
● Heavy metals
● Aerosols
● Further influencing variables:
– NH3: The NH3 concentration should be kept below 5 vpm. Loading with 300 vpm NH3
during a test resulted in a loss in sensitivity of approx. 20% within 14 days.
– SO2: The SO2 concentration should be kept below 10 vpm. Loading with 100 vpm SO2
during a test resulted in a cross-interference of <30 ppm H2S.
– NO: The NO concentration should be kept below 10 vpm. Loading with 200 vpm NO
during a test resulted in a cross-interference of <100 ppm H2S.
H2 influence
The 5000 ppm sensor can be damaged by a flow of H2 >2%. Although the cross-sensitivities
are low, the influence of H2 on the electrolyte results in a sluggish response of the sensor
and drifting of the baseline. This process is reversible, i.e. the sensor recovers in the
absence of H2.
H2 in the sample gas results in a zero drift. The magnitude and direction of the drift can differ
from sensor to sensor, and also depend on the previous loading of the sensors and the H2
concentration of the sample gas. With constant loading, this drift becomes stationary after a
few hours. The absence of H2 generates a countermovement with the same order of
magnitude and of similar duration. The sensor regenerates itself within a few hours.

Application note
9.1 H2S sensor with 'large' measuring range
Calibration and basic conversion
The H2S concentration of the sample gas itself initially leads to a zero drift toward larger
measured values. This drift stops after a while (approx. 1 hour). The drift is reversed when
the H2S concentration is reduced and returns toward zero. The magnitude of the deviation
depends on the H2S concentration. This drift is caused by the chemical conversion of the
quantity of H2S dissolved in the electrolyte.
Therefore make sure during the monthly calibration with calibration gas that the duration of
the calibration is approximately as long as the AUTOCAL time. In this case this is 5 minutes
since the AUTOCAL time for this application is 5 minutes. Optimum calibration accuracy is
achieved in this manner.
Calibration of the measured value drift
The deflection signal of the sensor is subject to drift. This drift can be detected only through
regular review and corrected as needed. This involves using a calibration gas with a defined
concentration of hydrogen sulfide.
To keep potential measurement uncertainty within strict limits, we recommend a monthly
calibration with a calibration gas with a concentration of 2500 ... 3000 vpm H2S.
When using smaller H2S concentrations, the technical specifications are changed linearly
(shifting of characteristic). For example, a calibration gas with a concentration of 1000 vpm
H2S results in a variation in output signal of 2500/1000 = 25 vpm * 2.5/1 ~ >60 vpm.

Reason: H2S is highly soluble in water and accumulates in the condensate. This
accumulation increases as the sample gas pressure increases. This effect can result in
significant delays in the response time.
Gas moisture
The calibration gas must have the same moisture as the sample gas.
If the sensor is used with a very dry gas for a longer period, e.g. when feeding biogas into
the natural gas network, it is necessary to carry out an AUTOCAL with ambient air every 60
minutes. The dew point of the air should be in the range of approx. 9 °C ... 12 °C
(48 °F ... 54 °F). The AUTOCAL purge time should be at least 5 minutes. This prevents
premature drying-out of the sensor.
H2 influence
The internal design of the 5/50 ppm sensor means that it is immune to the influence of H2.
NH3 influence
Loading of 300 vpm NH3 results in destruction of the H2S sensor within 2 to 3 days.
AUTOCAL / zero
An AUTOCAL of the zero point should be carried out every 60 minutes. On the one hand,
this is used to protect the sensor, but it also compensates the influence of temperature
variations during the day.

regular review and corrected as needed. This involves using a calibration gas with a defined

The analyzer can detect and display various fault statuses. These fault statuses are divided
into maintenance requests and faults.
11.1
Maintenance requests
Maintenance requests are references to certain changes in the analyzer which - at the time
of occurrence - have no influence on the analyzer measurements. However, remedial
measures are recommended to guarantee that measurements remain possible.
If the analyzer is in measuring mode, you can recognize the occurrence of a maintenance
request in that an "M" appears at the right edge of the measurement screen.
Maintenance requests are logged and can be called in input mode
using the menu path "Analyzer status - Status - Maintenance requests" (see section Analyzer status: Status: Maintenance request
(Page 105)). The corresponding message texts are stored. You can

Error and system messages
11.1 Maintenance requests
The analyzer outputs a maintenance request in the following cases:
● Message "AUTOCAL drift beyond tolerance"
The zero drift of a component is too large during the AUTOCAL procedure. The
AUTOCAL parameters can be entered as described in section Calibration:
AUTOCAL/drift values (Page 124). Using the conditions defined for the AUTOCAL
deviation (see section Configuration: Special functions: AUTOCAL deviation (Page 146)),
the actual deviation may deviate from the maximum permissible value. In such cases it
may be meaningful to set a shorter interval between two AUTOCAL procedures. If this
does not improve the situation, contact the servicing department.
● Message "O2 sensor"
The measured voltage of the O2 sensor has dropped as a result of aging, but is still within
the permissible range. This means that it is not necessary to replace the O2 sensor
immediately, but this will soon be exhausted. This would be the correct time to order a
new O2 sensor.
● Message "Temperature beyond tolerance"
The contrast control is no longer guaranteed if the LCD temperature is outside the
permissible tolerance. It may then be difficult to read the display, or it could remain dark
in the worst case. If this fault occurs because of an excessively high ambient
temperature, provide sufficient ventilation or air conditioning. If the fault still occurs,
contact the servicing department.
● Message "H2S sensor status"
If this message occurs, the measuring reserve of the H2S sensor is almost used up. We
recommend that you then replace the sensor. If the measuring reserve of the H2S sensor
is used up completely, the fault message "Measured value channel 3 beyond tolerance"
is displayed. A measurement is no longer possible.
● External maintenance requests
These are signaled via the binary inputs. The analyzer must be equipped with an add-on
board for this.

12.2 Scrapping the analyzer
Disposal of the electrochemical oxygen sensor
The exhausted or faulty O2 sensor is hazardous waste and must be packed and disposed of
accordingly!
The exhausted O2 sensor is electronic waste with the code number 160215, that is, a
'dangerous component removed from used devices'. It must therefore be disposed of
correctly and in an environmentally-friendly manner by a local waste disposal company.
WARNING
Danger of chemical burns
The O2S sensor contains acetic acid, which leads to burns on unprotected skin.
Therefore do not use any tools when replacing the sensor module which could damage the
sensor due to sharp edges or squeezing.
If contact with the acid occurs nevertheless, rinse the affected skin immediately with plenty
of water!
Disposal of hydrogen sulfide sensor
The exhausted or faulty H2 sensor is hazardous waste and must be packed and disposed of
accordingly!
The exhausted H2S sensor is electronic waste with the code number 160215, that is, a
"dangerous component removed from used devices". It must therefore be disposed of
correctly and in an environmentally-friendly manner by a local waste disposal company.
WARNING
Danger of chemical burns
The H2S sensor contains sulfuric acid, which leads to burns on unprotected skin.
Therefore do not use any tools when replacing the sensor module which could damage the
sensor due to sharp edges or squeezing.

Returned delivery
Note
Return delivery of contaminated device components
Device components which have come into contact with radioactive gases or substances, or
have been exposed to radioactive or high-energy radiation, may no longer be returned.
The owner of the device must ensure in such cases that the contaminated device
components are disposed of correctly in accordance with the local directives at the location
of use.
The gas analyzer or replacement parts should be returned in their original packaging. If the
original packaging is no longer available, we recommend that you wrap the device in plastic
foil and pack it with shock-absorbing material (wood wool, cellular rubber, or similar material)
in a sufficiently large box. If you use wood shavings, the stuffed layer on each side should be
at least 15 cm thick.
For overseas shipping, shrink-wrap the devices in an additional PE foil which is at least 0.2
mm thick, with a desiccant (e.g. silica gel) enclosed! For this type of shipping, you must also
line the inside of the transport container with a double layer of tar paper.
If you return your device for repair, enclose the filled-in decontamination declaration as well
as the filled-in fault description. In the case of guarantee claim, please enclose your
guarantee card.
Decontamination declaration
With this declaration you confirm "that the device/spare part has been thoroughly cleaned, is
free of residues, and that the device/spare part represents no danger for mankind and
environment."
If the returned device/spare part has come into contact with poisonous, corrosive, flammable
or polluting substances, you must thoroughly rinse, clean and neutralize the device/spare

ESD guidelines

ESD guidelines
Definition of ESD
All electronic modules are equipped with large-scale integrated ICs or components. Due to
their design, these electronic elements are highly sensitive to overvoltage, and thus to any
electrostatic discharge.
The electrostatic sensitive components/modules are commonly referred to as ESD devices.
This is also the international abbreviation for such devices.
ESD modules are identified by the following symbol:
NOTICE
ESD devices can be destroyed by voltages well below the threshold of human perception.
These static voltages develop when you touch a component or electrical connection of a
device without having drained the static charges present on your body. The electrostatic
discharge current may lead to latent failure of a module, that is, this damage may not be
significant immediately, but in operation may cause malfunction.

ESD guidelines
B.1 ESD guidelines
Electrostatic charging
Anyone who is not connected to the electrical potential of their surroundings can be
electrostatically charged.
The figure below shows the maximum electrostatic voltage which may build up on a person
coming into contact with the materials indicated. These values correspond to IEC 801-2
specifications.
Figure B-1
Electrostatic voltages on an operator
Basic protective measures against electrostatic discharge
● Ensure good equipotential bonding:
When handling electrostatic sensitive devices, ensure that your body, the workplace and
packaging are grounded. This prevents electrostatic charge.
● Avoid direct contact:
As a general rule, only touch electrostatic sensitive devices when this is unavoidable (e.g.
during maintenance work). Handle the modules without touching any chip pins or PCB
traces. In this way, the discharged energy can not affect the sensitive devices.
Discharge your body before you start taking any measurements on a module. Do so by
touching grounded metallic parts. Always use grounded measuring instruments.
