1.6 X-STREAM X2GP
The Service Interface is elec-
trically connected to the unit’s
electronic components. If it is
incorrectly handled, damage to
the unit may result.
The Service Interface may only
be used by EMERSON service
personnel or specially trained
staff.
Gas connections
Depending on the conguration of the unit
(number of measurement channels and serial
or parallel connection), sample and calibra-
tion gases are fed into the unit via up to 8
threaded connectors mounted on the rear
panel. The conguration of the connectors is
indicated on an adhesive label located near
the connectors.
An additional, optional connection can be
used for purging the device with
•
inert gas to minimize interference from the
ambient atmosphere when measuring small
concentrations (e.g. of CO
2
)
or
•
air or inert gas when measuring corrosive
and/or ammable gases.
For further information, see section
1.2.6, page 1-5.
Special components
For the analysis of aggressive and/or am-
mable gases, infallible components (WLD;
photometer under development) can be used.
The risk of an uncontrolled release of gases
due to a leak can be minimized by the use
of stainless steel piping and clamping rings.
Further details about the infallible contain-
ment are in the separate manual supplied with
units containing such parts.
Furthermore, intrinsically safe measuring
cells, which prevent the ignition of gas mixtu-
res in the case of a failure, can also be used.
Module type XCA
The full 19-in unit is also available as an ana-full 19-in unit is also available as an ana-
lyzer module without the front control panel,
which can, for example, be integrated into a
measuring system in which control and ana-
lysis of data is performed via interface by an
external data acquisition system.
