Fidas24: Information on the safe operation of the gas analyzer
CAUTION
The gas analyzer uses hydrogen as a combustion gas!
All the information and instructions contained in this operating instruc-
tion must be complied with without fail to ensure safe operation of the
gas analyzer!
Measures of the manufacturer
The following measures ensure that the enrichment of combustion gas or an
explosive mixture of combustion gas and ambient air cannot occur inside
the gas analyzer during normal operation:
The seal integrity of the combustion gas feed path is checked for a
leakage rate of < 1 × 10−4hPa l/s before delivery.
The combustion gas/air mixture (before and after the ignition point) is
diluted in the detector with compressed air.
The combustion gas feed is not connected to the supply during start-up
until the internal nominal pressures have been set.
The combustion gas feed is switched off if the internal nominal pres-
sures cannot be set during the ignition phase (e.g. because of insuffi-
cient compressed air or combustion air feed).
The combustion gas feed is switched off after several unsuccessful igni-
tion attempts.
If the flame goes out during operation the combustion gas feed is
switched off if the following ignition attempts are unsuccessful.
The interior of the gas analyzer is not assigned to an (explosion protection)
zone; no explosive gas mixture can escape from it to the outside.
Conditions to be complied with by the end user
The end user must comply with the following prerequisites and conditions
to ensure safe operation of the gas analyzer:
The gas analyzer may be used for the measurement of flammable gases
provided that the flammable portion does not exceed 15 vol.% CH4or
C1 equivalents.
The relevant safety regulations for working with flammable gases must
be complied with.
The gas connection diagram (see page 79) must be complied with when
connecting the combustion gas and combustion air.
The combustion gas feed path in the gas analyzer may not be opened!
The combustion gas feed path can become leaky as a result! Escaping
combustion gas can cause fires and explosions, also outside the gas an-
alyzer!
If the combustion gas feed path in the gas analyzer has been opened,
however, it must always be checked for seal integrity (see page 118) with
a leak detector after it has been sealed again (leakage rate
< 1 × 10−4hPa l/s).
The seal integrity of the combustion gas line (see page 116) outside the
gas analyzer and the combustion gas feed path (see page 118) in the gas
analyzer must be checked on a regular basis.
The maximum pressures of combustion gas and combustion air (see
page 34) may not be exceeded.
The maximum combustion gas flow (see page 34) may not be exceeded.

10 EL3000 CONTINUOUS GAS ANALYZERS | CI/EL3000-EN REV. B
The combustion gas flow rate must be limited to a maximum of
10 l/h of H2or 25 l/h of H2/He mixture. For this purpose, the end user
has to provide suitable measures (see page 34) outside the gas analyzer.
A shut-off valve (see page 34) must be installed in the combustion gas
supply line to increase the safety in the following operating states:
Shutting down the gas analyzer,
Failure of the instrument air supply,
Leakage in the combustion gas feed path inside the gas analyzer.
This shut-off valve should be installed outside the analyzer house in the
vicinity of the combustion gas supply (cylinder, line).
If there is no automatic shut-off of the combustion gas supply to the
gas analyzer in case of an instrument supply failure, a visible or audible
alarm must be triggered.
When measuring flammable gases, it must be made sure that in case of
a failure of the instrument air supply or of the analyzer module itself the
sample gas supply to the analyzer module is shut off and the sample gas
path is purged with nitrogen.
The unobstructed exchange of air with the environment must be possi-
ble around the gas analyzer. The gas analyzer may not be directly cov-
ered. The openings in the housing towards the top and at the side may
not be closed. The distance to laterally adjacent built-in components
must be at least 4 mm.
If the gas analyzer is installed in a closed cabinet, adequate ventilation
of the cabinet must be provided (at least 1 change of air per hour). The
distance to adjacent built-in components towards the top and at the
side must be at least 4 mm.

Special requirements
The cables have to be properly inserted in the screwed cable glands and
sealed by screwing the nut firmly in order to comply with degree of case
protection IP65. Cable connectors not in use have to be closed with
suitable vent plugs in order to ensure degree of case protection IP65
here as well.
Purging gas connections not in use during operation have to be closed
with vent plugs.
If the installation site of the gas analyzer is hazardous, the case must not
be opened live and electrical connectors must not be disconnected live.
Due to the low mechanical stability of the display window, the gas ana-
lyzer has to be installed and operated in such a way that mechanical
damage to the display window with an energy exceeding 2 Joule is ruled
out. In the event that the display window is still damaged making it im-
possible to comply with degree of case protection IP65, the gas analyzer
has to be shut down, secured against re-starts and it has to be repaired.
Due to the low UV resistance of the plastic parts of the housing, the gas
analyzer has to be installed and operated in such a way that exposure to
UV radiation is ruled out. In the event that the housing is still damaged
by UV radiation making it impossible to comply with degree of case
protection IP65, the gas analyzer has to be shut down, secured against
re-starts and it has to be repaired.
Replacing the battery
The battery may not be replaced in an explosive atmosphere.
Only the original battery may be used as replacement: Lithium button
cell battery Varta type no. 6032 (3 V CR 3032).
Important safety note
According to EU Directive 2014/34/EU and the general requirements for
equipment installed in explosive atmospheres stated in IEC 60079-0, the
scope of the certification of our equipment is limited to atmospheric condi-
tions, unless specified otherwise in our certificates.

EL3000 CONTINUOUS GAS ANALYZERS | CI/EL3000-EN REV. B 19
Uras26: Preparation for installation
Sample gas
Sample gas inlet conditions
The analyzer must not be used for measurement of ignitable gas/air or
gas/oxygen mixtures.
Temperature The dew point of the sample gas must be at least 5 °C
lower than the lowest ambient temperature in the overall
sample gas path. Otherwise, a sample gas cooler or con-
densate trap is required.
Pressure The analyzer is operated under atmospheric pressure; the
sample gas outlet is open to atmosphere. Internal pres-
sure drop < 5 hPa with standard flow rate 60 l/h. Permis-
sible absolute pressure range: 800 to 1250 hPa. Operation
under lower absolute pressure (e.g. at altitudes above
2000 m) on request. Overpressure in the sample cell max.
500 hPa.
Flow 20 to 100 l/h
Corrosive gases
Highly corrosive associated gas components such as chlorine (Cl2) or hy-
drogen chlorides (e.g. wet HCl) as well as gases or aerosols containing chlo-
rine must be cooled or pre-absorbed.
Flammable gases
In the version with gas lines and connectors made of stain-less steel the
analyzer is suitable for measuring flammable gases in general purpose envi-
ronment. The special requirements for the measurement of flammable gas-
es (see page 43) must be observed.

* Test gas mixture for multiple sample components possible if no
cross-sensitivity is present
Dew point
The dew point of the test gases must be approximately the same as the dew
point of the sample gas.
NOTE
The notes for calibrating must be considered.
Pressure sensor
The pressure sensor is installed in the gas analyzer ex works. Depending on
the version of the gas analyzer it is internally connected as follows:
Internal gas lines made as hoses:
Pressure sensor in the outlet of sample cell 1 with one sample cell
and with separate gas feed paths,
Pressure sensor in the outlet of sample cell 2 with two sample cells
in series..
Internal gas lines made as stainless steel pipes:
Pressure sensor connected to a connection port via an FPM tube.
