SAFETY INSTRUCTIONS
Intended Use Statement
X-STREAM flameproof analyzers are intended to be used in hazardous (classified) areas of Zone 1
or Division 2, depending on the nameplate label marking. Installation in Zone 0 or Division 1 is
not permitted and causes risk of explosion!
X-STREAM series gas analyzers are intended to be used as analyzers for industrial pur
-
poses. They must not be used in medical, diagnostic or life support applications. Using
X-STREAM
Enhanced
analyzers as safety devices is prohibited where redundancy and/or SIL
classification or equivalent is needed. No independent agency certifications or approvals are to
be implied as covering such applications!
The X-STREAM enhanced flameproof analyzer can measure flammable and non-flammable gases
with various measurement methods. Ambient temperature range is -20°C to 55°C. The maximum
sample gas pressure inside the containment system is 1100 hPa (1.45 psig). For flammable gas
-
es the maximum gas flow into the containment is 1.5 l/min and need to be controlled externally.
With a special option maximum sample gas pressure in the containment system is 1500 hPa
(7.25 psig). Then the maximum flow into the containment system is 1.0 l/min. Applications with
an internal release of oxygen in concentrations greater than that found in air or other oxidizer are
outside the scope of the used standards and the X-STREAM enhanced flameproof certificate.
Sample gases are allowed to contain Oxygen only up to 21%.
Equipment for flammable sample gas can be identified by the ordering code on level 2 (Options A,
B, ...) and the respective note on the type plate. Equipment for non-flammable sample gas can
be identified by the ordering code on level 2 (Options 1, 2, ...) and the respective note on the
type plate.
It is not allowed to measure sample gas which is explosive frequently or over long periods.
Special version “Vapor Recovery” is for ambient temperature -20°C to 50°C and non-flammable
sample gas only.
General Safety Notice / Residual Risk
If this equipment is used in a manner not specified in these instructions, protective systems may
be impaired.
Despite of incoming goods inspections, production control, routine tests and application of state-
of-the-art measuring and test methods, an element of risk remains when operating a gas analyzer!
Even when operated as intended and observing all applicable safety instructions, some residual
risks remain, including, but not limited to, the following:
•
An interruption of the protective earth line, e.g. in an extension cable, may result in risk to
the user.
•
Live parts are accessible when operating the instrument with doors open or covers removed.
•
The emission of gases hazardous to health may even be possible when all gas connections
have been correctly made.
Avoid exposure to the dangers of these residual risks by taking particular care when installing,
operating, maintaining and servicing the analyzer.
