4-1 Installation - Abstract
To stay in compliance with regulations regar-
ding electromagnetic compatibility it is recom-
mended to use only shielded cables, as
optionally available from Emerson Process
Management or equivalent. Customer has to
take care that the shield is connected in pro-
per way. Shield and signal connector enclosure
need to be conductively connected, submin-d-
plugs and sockets must be screwed on the
analyzer.
Using external submin-d-to-terminal adaptor
elements (option) affects electromagnetic
compatibility. In this case the customer has to
take measures to stay in compliance and has
to declare conformity, when required by legis-
lation (e.g. European EMC Directive).
4-2 Gas Conditioning
Furthermore the gases must be
- dry
- free of dust
- free of aggressive components affecting
gas path materials (e.g. by corrosion).
If moisture can not be avoided take care that
the gas‘ dew point is at least 18 F (10 °C) below
ambient temperature to avoid condensation
within the gas path.
The fieldhousing version X-STREAM F offers
the option to be ordered with thermostat
controlled pipes allowing a maximum dew point
of 77 °F (25 °C).
Pressure and flow must be within the limits given
by the measurement specifications table 3-7
(
3-4, page 3-17).
To ensure trouble-free analyzer operation
one has to attach great importance to gas
conditioning:
All gases must be conditioned
before supplying!
When supplying corrosive
gases ensure that gas path
components are not affected!
Flammable gases must not
supplied without additional
protective measures!
It is prohibited to supply explo-
sive gases!
