3. Supply Voltage

◆ Verify correct polarity for 24 V DC - operation !

◆ This product is a Safety Class 1 instrument (provided with a protective earth terminal).

To prevent shock hazard, the instrument chassis and cabinet must be connected to an
electrical ground. The instrument must be connected to the AC power supply mains through
a three-conductor power cable , with the third wire firmly connected to an electrical ground
(safety ground) at the po wer outlet. If the instrument is to be energized via an external power
supply, that goes f or the power supply too.
Any interruption of the protective (grounding) conductor or disconnection of the protectiv e
earth terminal will cause a potential shock hazard that could result in personal injury.
Deliberate disconnection is inadmissible / prohibited !

◆ Use only power supply VSE 2000 or equiv alent power supplys to be in agreement with the
CE - conformity.

◆ In case of exchanging fuses the customer has to be certain that fuses of specified type and
rated current are used. It is prohibited to use repaired fuses or def ective fuse holders or to
short-circuit fuse carriers (fire hazard).

◆ Always disconnect po wer, discharge circuits and remove e xternal voltage sources before
troubleshooting, repair or replacement of any component !

Any work inside the instrument without switching off the power must be
performed by a specialist, who is familiar with the related danger, only !

4. Connection Cables

SAFETY SUMMARY

ELECTROSTATIC DISCHARGE

5. Electrostatic Discharge

The electronic parts of the analyzer can be irreparably damaged if exposed to electrostatic
discharge (ESD).

The instrument is ESD protected when the covers have been secured and safety precautions
observed. When the housing is open, the internal components are not ESD protected anymore.

Although the electronic parts are reasonably safe to handle, you should be aw are of the following
considerations:

Best ESD example is when you walk ed across a carpet and then touched an electrically grounded
metal doorknob. The tiny spark which has jumped is the result of electrostatic discharge (ESD).

You prevent ESD by doing the following:

Remove the charge from your body before opening the housing and maintain during work with
opened housing, that no electrostatic charge can be built up.

Ideally you are opening the housing and working at an ESD - protecting workstation.
Here you can wear a wrist trap.

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

Discharge the electric charge from your body. Do this by touching a device that is electrically
grounded (any device that has a three - prong plug is electrically grounded when it is plugged into
a power receptacle).
This should be done several times during the operation with opened housing (especially after
leaving the service site because the movement on a low conducting floors or in the air might cause
additional ESDs).

PHOTOMETER ASSEMBLY

PYROELECTRICAL DETECTOR

2. Photometer Assembly

Depending on gas component and measuring range, different photometer assemblies will be
realized in BINOS® 100 (M).
Optional the photometer can be sealed to ambient air. In this case all parts are sealed with O ­rings.
The entire photometer assembly is mounted as a unit on the main circuit board (BKS) by means
of a bracket. The main circuit board is inserted into guide rails in the analyzer housing, to which
the front panel (membrane keypad) and the rear panel are assembled.

2.1 Photometer with Pyroelectrical Detector (Solid-state detector)

Fig. 2-1 shows the schematical photometer assembly for dual - channel operation.

The base element for the photometer assembly is the chopper housing (03), upon which the light
source (thermal radiator, 07), the analysis cell (cuvette , 09), and the signal detection unit [filter cell
(14/15), pyroelectrical (solid-state) detector with integrated preamplifier (16)] are all mounted.

The chopper housing also incorporates the duplex filters (04/05) for the selection of spectral band­pass ranges from the broadband emission of the light sources.

Between the two halves of the chopper housing (03), which are sealed together with an O-ring,
is the chopper blade, driven by a stepping motor. Both the chopper housing and the motor
encapsulation are hermetically sealed with respect to the ambient in order to prevent entry of
gases, such as atmospheric CO2, which could produce background absorptivity (preabsorption)
leading to drift effects. An absorber material provides f or constant remo v al of an y tr aces of CO
which may enter the interior of the chopper housing via diffusion.

2

The chopper housing additionally incorporates a photoelectric gate for providing a reference
signal for the phase angle of the chopper blade, plus a temperature sensor (28) for monitoring
continuously the photometer assembly temperature. This temperature information is used by the
signal processing electronics for the compensation of thermal effects .

PHOTOMETER ASSEMBLY

PYROELECTRICAL DETECTOR

The analysis cells are merely aluminum tubes equipped with sample gas inlet and outlet fittings.
This extremely simple and windowless design enab les easy cleaning of the cells in the e v ent of
contamination.
The only optical surfaces which also might become contaminated are the chopper windows and
the windows of the filter cells; these are accessible upon removal of the cell body.

The filter cell (14/15) has a necked conical shape f or optimal adaptation of the analysis cell beam
cross - sectional profile to the active area of the detectors.

For high measurement ranges (up to 100 %), an adapter cell (10) is required.
The use of a spacer ring (08) creates an analysis cell in the space between the exit window of the
adapter cell and the entrance window of the filter cell.

2.2 Photometer with Gas Detector

Fig. 2-2 shows schematically the photometer assembly.

This assembly is similar to the assembly with p yroelectrical detector.

The analysis cells are separated into two halves b y means of an internal wall along its axis and
both ends are sealed with windows. This divided the analysis cell in measuring side and reference
side.
Sample gas is flowing through measuring side while the closed reference side contains inert gas
(N2).
To prevent measuring errors by preabsorption, two absorber , fitted to the gas connections of the
reference side, absorb CO2 - parts.

The filter cell has a single - stage conical shape.

The gas detector is connected by a shielded cable to the separate preamplifier.
For small measuring ranges the preamplifier is mounted at the analysis cell.
For high measuring ranges the preamplifier is mounted at two holding clamps.

MEASURING PRINCIPLE

IR - MEASUREMENT

3. Measuring Principle

Depending on analyzer model different measuring methods will be used.

3.1 IR - Measurement

The analyzers are non - dispersive infrared photometers (NDIR) using measurement of selectiv e
radiation in a column of gas.
The measuring effect devided from absorption of infra - red radiation is due to the gas being
measured. The gas - specific wavelengths of the absorption bands characterize the type of gas
while the strength of the absorption gives a measure of the concentration of the component
measured. Due to a rotation chopper wheel, the r adiation intensities coming from measuring and
reference side of the analysis cell produce periodically changing signals within the detector.
The detector signal amplitude thus alternates between concentration - dependent and concen­tration - independent values. The difference between the two is a reliable measure of the
concentration of the absorbing gas component.

Dependent on measuring component and measuring concentration, two different measuring
methods will be used.

3.1.1 Interference Filter Correlation (IFC Principle)

The undivided analysis cell is alternately illuminated with filtered light concentrated in one of two
spectral separated wav e length ranges. One of these two spectrally separ ated wave length bands
is chosen to coincide with an absorption band of the sample gas, and the other is chosen such
that none of the gas constituents expected to be encountered in practice absorbs anywhere within
the band.

The spectral transmittance curves of the interference filters used in the BINOS® 100 analyzer and
the spectral absorption of the gases CO and CO2 are shown in Fig. 3-1. It can be seen that the
absorption bands of these gases each coincide with the passbands of one of the interference
filters. The fourth interference filter , used for generating a ref erence signal, has its passband in a
spectral region where none of these gases absorb. Most of the other gases of interest also do not
absorb within the passband of this reference filter.

The signal generation happens by a pyroelectrical (solid-state) detector.

The detector records the incoming IR - radiation. This radiation intensity is reduced by the
absorption of the gas at the according wave lengths. By comparing the measuring and reference
wave length an alternating voltage signal is developed. This signal results from cooling and heating
of the pyroelectrical material of the detector.

IR - MEASUREMENT

3.1.2 Opto - Pneumatic Measuring Principle

A thermal radiator generates the infrared radiation passing through a chopper wheel. This
radiation alternately passes through a filter cell and reaches reaches the measuring and reference
side of the analysis cell with equal intensity.

After passing another filter cell the radiation reaches the pneumatic detector.

The pneumatic detector compares and ev aluates the radiation from the measuring and reference
sides and converts them into voltage signals proportional to their intensity via a preamplifier.

The detector consists of a gas-filled absorption and a compensation chamber which are
interconnected via a flow channel.

MEASURING PRINCIPLE

IR - MEASUREMENT

In principle the detector is filled with the infrared active gas to be measured and is only sensitive
to this distinct gas with its characteristic absorption spectrum. The absorption chamber is sealed
with a window which are transparent for infrared r adiation [usually CaF2 (Calcium fluoride)].

When the IR - radiation passes through the reference side of the analysis cell into the detector,
no preabsorption occurs. Thus the gas inside the absorption chamber is heated, expands and
some of it passes through the flow channel into the compensation chamber .

When the IR - radiation passes through the open measurement side of the analysis cell into the
detector, a part of it is absorbed depending on gas concentration. The gas in the absorption
chamber then is heated less than in the case of radiation coming from reference side. Absorption
chamber gas become colder, gas pressure in the absorption chamber is reduced and some gas
of compensation chamber passes through the flow channel into the absorption chamber.

The flow channel geometry is designed in such a way that it hardly impedes the gas flow by
restriction. Due to the radiation of chopper wheel, the different radiation intensities lead to
periodically repeated flow pulses within the detector.

The microflow sensor ev aluates this flow and converts it into electrical voltages.
The electronics, which follow , evaluate the signals and convert them into the corresponding display
format.

3.1.3 Technique

The broadband emission from two IR sources (in the case of dual - channel analyzers) passes
through the chopper blade, then, if IFC, through combinations of interference filters, if
optopneumatic principle depending on application through an optical filter (reduction of influ­ences) and enters the analysis cells. The light transmitted through these cells is f ocused by filter
cells onto the according detector. The preamplified detector output signal is sent to microprocessor
circuitry , which converts the analytical signals to results expressed directly in physical concentr a­tion units (Vol.-%, ppm, mg/Nm3 etc.).

The oxygen senor incorporate a lead/gold oxygen cell with a lead anode (1) and a gold cathode
(2), using a specific acid electrolyte. T o avoide moisture losses at the gold electrode a sponge sheet
is inserted on the purged side.

Oxygen molecules diffuse through a non-porous T eflon membrane (4) into the electrochemical cell
and are reduced at the gold-cathode. Water results from this reaction.
On the anode lead oxide is formed which is transferred into the electrolyte. The lead anode is
regenerated continuously and the electrode potential therefore remains unchanged for a long
time.
The rate of diffusion and so the response time (t90) of the sensor is dependent on the thickness
of the Teflon membrane.

5. Preparation

Please check the packing and its contents immediately upon arrival.
If any damage or missing items are found, then we request that you notify the forwarder to
undertake a damage surve y and report the loss or damage to us immediately.

5.1 Installation

The analyzer must not operate in explosive atmosphere without supplementary protective
measures !

The installation site for the analyzer has to be dry and remain above freezing point at all times.
The analyzer must be exposed neither to direct sunlight nor to strong sources of heat.
Be sure to observe the permissible ambient temperatures (c.f. Item 24: Technical Data).

For outdoor installation, we recommend to install the analyzer in a protectiv e cabinet. At least, the
analyzer has to be protected against rain (e.g., shelter).

The analyzer has to be installed as near as possible to the sample point, in order to av oid low
response time caused by long sample gas lines.
In order to decrease the response time, a sample gas pump with a matching high pumping rate
may be used. Ev entually, the analyzer has to be operated in the bypass mode or by an ov erflow
valve to prevent too high flow and too high pressure (Fig. 5-1).

GAS CONDITIONNING (SAMPLE HANDLING)

5.2 Gas Conditionning (Sample Handling)

The conditionning of the sample gas is of greatest importance for the successful operation of any
analyzer according to extractiv e method.

Only conditionned gas has to be supplied to the analyzer !

The gas has to fullfil the following conditions:

It must be

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

paths.

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

Data” of this manual.

Inflammable or explosive gas mixtures may not be intr oduced into the analyzer
without supplementary protective measures !

When analysing vapours, the dewpoint of the sample gas has to be at least 10 °C below the
ambient temperature in order to avoid the precipitation of condensate in the gas paths .

Suitable gas conditionning hardware may be supplied or recommended for specific analytical
problems and operating conditions.

5.2.1 Gas Flow Rate

The gas flow rate should be within the range 0.2 l/min to maxi. 1.5 l/min !

A constant flow rate of about 1 l/min is recommended.

PRESSURE CORRECTION / CROSS COMPENSATION

8.1 Pressure Correction

T o eliminate faulty measurements due to changes in barometric pressure or sample gas pressure,
the operator is offered the opportunity to enter the current pressure expressed in hP a (mbar) in
a range of 800 to 1300 hPa. The concentration values computed by the analyzer will then be
corrected to reflect the barometric pressure or sample gas pressure resp. entry.

The entry is effected using

and

It is possible to integrate a pressure sensor with a range of 800 - 1100 hPa.
The concentration values computed b y the analyzer will then be corrected to reflect the
barometric pressure to eliminate faulty measurements due to changes in barometric
pressure (see technical data). .
In this case it is not possible to enter pressure value manually. In attempting to enter
pressure value manually , the analyzer will automatically rev ert to the display of measured
pressure value.

CALIBRATION

9. Calibration

T o insure correct measurement results, zeroing and spanning should be carried out once a week.
Spanning can be performed only after zeroing before .

For the calibration procedure the required test gases hav e to be f ed to the analyz er through the
respective gas inlets (cf . section 5.3) with a no - back - pressure gas flo w rate of about 1 l/min (the
same as with sample gas) !

After switching on the analyzer, wait at least approx. 15 to 50 minutes
(depending on installed detectors) before admit gas to the analyzer !

Note !

For operation with optional, e xternal solenoid valves the solenoid v alves are activ ated automati­cally by the respective function (via digital outputs). If the analyzer is in “calibration mode”, a digital
status signal “calibration” can given optional (see Item 10.3).

Zeroing

For zeroing, the analyz er has to be flushed with nitrogen (N2) or adequate zerogas
(e. g. synth. air or conditionned air).

Spanning

The span gas concentration should be in a range of 80 % - 110 % of full - scale range !
For low er span gas concentrations the measuring accuracy could be lo wer for sample
gas concentrations, which are higher than the span gas concentration !
Spanning for o xygen measurement can be done using ambient air as span gas, if the
oxygen concentration is known and constant.

When using span gas mixtures the entry for “C.Cal” must be set to “0”
(see section 8.3) !

11. Measurement / Switching Off

11.1 Measurement

The primary step in the measurement of the concentration of a gas component is the admission
of sample gas to the analyzer.

Analyzer warming-up after switching on takes about 15 to 50 minutes,
depending on the installed detectors !

❍ Admit sample gas at the gas inlet fitting.

❍ Set the gas flow rate to approx. 1 l/min.

The analyzer must be in the “analysis mode”, i. e. the displays must show

Note !

If some other mode has been selected, the analyzer will automatically return to the analysis display
when a period of 60 - 120 seconds has elapsed after the last key actuation or after the last
completion of an operation !

SERIAL INTERFACE (OPTION)

GENERAL

12.2 General

The analyzer is equipped with a serial interface enabling communications with a host computer .
The host computer can call up, prescribe, or alter parameters, as well as initiate analyzer
operations, using standardized protocols. The optional BSI 10 plug in circuit board constitutes the
hardware interface. This may be configured as RS 232 C or RS 485 interface. The RS 485 interface
permits networking several analyzers. Each analyzer may then be addressed using an assign­ment numerical ID - code.

Communications are always initiated b y the host computer; i.e ., analyzer beha ve passiv ely until
the host computer requests information from them or demands commencement of an action.

Communications use so - called “telegrams” being exchanged between the host computer and
the analyzer(s). Syntax for these telegrams is established in protocols.

T elegrams alwa ys commence with the "$" start character, immediately follow ed by a three - digit
instruction code.

Subsequent elements of telegrams are segregated by the ";" h yphen c haracter .

The final element of all telegrams transmitted must be the “CR” termination character .

Upon receipt of the terminate character, the analyzer attempts to e valuate the current contents
of its input buffer as a valid telegram. If the syntax of the transmitted telegram is correct, the
analyzer will transmit a response telegram to the host computer. This consists of the start
character, an instruction code, requested data, a bloc k - parity byte, and the termination character.

If the syntax of the transmitted telegram was not correct, the analyzer will transmit a status telegram
containing an error message to the host computer. Each terminate character reception thus
initiates an analyzer response.

12 - 2

90002953(1) BINOS® 100(M) e [4.01] 25.09.96

SERIAL INTERFACE (OPTION)

GENERAL

T o avoid detecting transmission errors, the host computer can insert a message -length parity byte
immediately preceding the terminate character for verification by the analyzer.

The analyzer invariab ly transmits message - length parity bytes immediately preceding termina­tion characters.

The elapsed time between the reception of star t characters and termination characters is not
limited by the analyzer; i.e ., there are no “time - out” periods.

If the host computer transmits any new characters before the analyzer has responded to the
preceding telegram, the analyzer’s input buffer will reject them; i.e., these characters will be
ignored by the analyzer.

The transmission rate may be set between 600 and 4.800 baud.
An echo - mode may also be activ ated.

The analyzer software is configured such as that telegrams ma y be sent to the host computer at
time intervals of 150 ms and greater.

In contrast to RS 232 C operation, simultaneous transmission and reception is not implemented
in this standard. This would not result in damage to the electronics, but could lead to destroy of
data. The analyzer behav es passively in this mode of operation; i.e., it keeps its transceiver set f or
reception whenever it is not transmitting. Since the time periods for transmission and reception are
controlled by protocols, “data collisions” are excluded.

TELEGRAM SYNTAX

12.4 Telegram Syntax

Telegrams are assembled as f ollows:

12.4.1 Start Character ( “$” = Hex 24)

If the start character is missing, this will result in transmission of an appropriate status telegram
by the analyzer.

12.4.2 Terminate Character ( “CR” = Hex OD)

If the terminate character is missing, no decoding of the transmitted information will be performed,
and the analyzer will not respond. No response message will be transmitted.

12.4.3 Instruction Code

Each instruction is assigned a unique three digit numerical instruction code. If a received
instruction code should be other than three - digits in length or contain non - numerical ASCII­characters, the analyzer will transmit an appropriate status telegram. Reception of unassigned
instruction codes will also result in the transmittal of a status telegram.

In the RS 232 C mode of operation, the instruction code immediately follows the start character;
in the RS 485 mode of operation, the start character is followed by a two - digit de vice identification
code, the separator character. “;”, and a three - digit instruction code, in this order.

12.4.4 Hyphen Character ( “;” = Hex 3B)

Individual elements of a telegram line are separated by this hyphen character. Missing hyphen
characters can lead to misinterpretations of telegrams, and will result in transmission of an
appropriate status telegram.

STATUS TELEGRAM

12.4.5 Status Telegram

If telegram syntax is faulty, or analyzer is unable to act upon an instruction received, then the
analyzer will transmit a status telegram to the host computer .

These status telegrams are listed here for ref erence:

NUMERICAL REPRESENTATION / BLOCK PARITY CHECK

12.4.6 Numerical Representations

Telegrams may contain integers or real numbers. The f ormats for these numbers are subject to
the following restrictions.

Integers: - maximum value = 216 - 1

- positive numbers only accepted

- no decimal points allowed

Real: - maxim um of 6 digits accepted

- no alphabetic characters (e.g. 2.2E-6) allowed

- analyzer output is 6 - digit real numbers

12.4.7 Block Parity Check

The master control computer may insert a message - length parity byte into telegrams. These
invariably consist of tw o characters .

The message - length parity byte is the cumulatively EXCLUSIVE - OR correlation of all pre viously
transmitted characters of the telegram line. Representation is in hexadecimal format. For example,
if the decimal value should be decimal 13, this will be represented by the two characters “OD”, i.e.,
030H and 044H.

The verification procedure may be enabled or disabled at the analyzer (see Section 12.3.4).
