EL3000 CONTINUOUS GAS ANALYZERS | OI/EL3000-EN REV. D 5
Intended use
The gas analyzer is designed for continuous measurement of the
concentration of individual components in gases or vapors.
Any other use is not approved.
The intended use also includes taking note of this operating
instruction.
Note
The version for the measurement of flammable gases and the
explosion-proof design in degree of protection II 3G is designed
for various variants of the gas analyzer and for different
applications.
Measurement of flammable gases
Explosion hazard
Explosion hazard when operating the gas analyzer in
potentially explosive atmospheres.
• Only operate the gas analyzer in the version with stainless
steel gas lines and gas connections (models EL3020 and
EL3040), for the measurement of flammable gases and
vapors, outside hazardous areas.
Observe the following information when measuring flammable
gases*:
• The gas analyzer may only be used for the measurement
of non-incendive gas / air or gas / oxygen mixtures.
• The special conditions for the measurement of flammable
gases (see Special conditions for the model EL3020 gas
analyzer for the measurement of flammable gases on
page 17) must be observed.
• The oxygen sensor, as well as the assemblies of the
integral gas feed (option “Integrated gas feed option –
only in model EL3020, not for Limas23, ZO23, Fidas24)
may not be used for the measurement of flammable
gases.
* A flammable gas is a gas that can be ignited by adding air.
Operation in hazardous areas
Explosion hazard
Explosion hazard when measuring flammable gases in
hazardous areas.
• The gas analyzer in the explosion-proof design (model
EL3040) may only be used for the measurement of non-
flammable gases and vapors.
The model EL3040 gas analyzer is available in explosion-proof
design with degree of protection II 3G (see Use in potentially
explosive atmospheres on page 10).
Important safety instructions
In accordance with the EU Directive 2014/34/EU and the general
requirements for explosion protection and as specified in the
IEC 60079-0 standard, the scope of approvals for our explosion-
protected apparatus is limited to atmospheric conditions,
unless expressly stated otherwise in the certificates.
This also includes the sample gas that is fed in.
Definition of atmospheric conditions
80 to 110 kPa (0.8 to 1.1 bar)
Ambient air with standard oxygen content, typically 21% vol.%
If the atmospheric conditions are not complied with, the
operator is obliged to guarantee the safe operation of our
devices in the absence of the recommended atmospheric
conditions, by means of further measures (e.g. evaluation of the
gas mixture or explosion pressure) and / or supplementary
protective devices.
Improper use
The following are considered to be instances of especially
improper use of the device:
• For use as a climbing aid, for example for mounting
purposes.
• For use as a bracket for external loads, for example as a
support for piping, etc.
• Material application, for example by painting over the
housing, name plate or welding/soldering on parts.
• Material removal, for example by spot drilling the
housing.
