EL3000 CONTINUOUS GAS ANALYZERS | CI/EL3000-EN REV. C 7
• The combustion gas flow rate must be limited to a
maximum of 10 l/h H
2
or 25 l/h H
2
/He mixture. Suited
measures (see Combustion gas parameter on page 31)
outside the gas analyzer must be provided by the
operator for this purpose.
• In order to increase the safety level under the following
operational conditions, a shut-off valve (refer to
Combustion gas parameter on page 31) must be installed
in the combustion gas supply line:
– when shutting down the gas analyzer,
– in case of instrument air supply failure,
– in case of a leak in the combustion gas 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).
• Should the combustion gas supply to the analyzer module
not shut off automatically in the event of an instrument
air supply failure, an alarm that is visible or audible to the
operator must be triggered (refer to Failure of
instrument air supply on page 108).
• When measuring combustion gases, it must be ensured
that if either the instrument air supply or the analyzer
module should fail, the sample gas supply to the analyzer
module will be shut off and the sample gas path purged
with nitrogen.
• The unobstructed exchange of air with the environment
must be possible around the gas analyzer. The gas
analyzer must not be directly covered. 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.
Notes on data safety
This product is designed to be connected to a network interface
and to communicate information and data via this network
interface.
It is the operator’s sole responsibility to provide and
continuously ensure a secure connection between the product
and your network or any other network (as the case may be).
The operator must implement and uphold appropriate measures
(such as the installation of firewalls, the application of
authentication measures, data encryption, the installation of
anti-virus programs, etc.), in order to protect the product, the
network, the connected systems and the interface from any
breaches of security, unauthorized access, interference,
intrusion, loss and/or theft of data or information.
ABB Automation GmbH and its subsidiaries do not accept
liability for any damage and/or loss resulting from such
breaches of security, unauthorized access, interference,
intrusion or loss and/or theft of data or information.
