Instruction Manual
HASX2E-IM-HS
02/2012
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 channels, series or parallel pi-
ping), up to eight tube ttings are provided for
the supply of sample and calibration gases.
The assignments of the ttings is given on an
adhesive label situated near the ttings.
A further optional tube tting enables the
housing to be purged with either
• Inert gas to minimize interference from
ambient atmospheres when measuring
very small concentrations (e.g. CO
2
)
or:
• air or inert gas whe measuring aggressive
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 (TCD)
can be used. The risk of an uncontrolled
release of gases due to a leak can be mi-
nimized by the use of stainless steel piping
and clamping rings. Further details about the
infallible containment are in the separate ma-
nual 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.

Dual compartment variation XXF
The dual compartment variation XXF sup-
ports separating electronics and physics,
e.g. for measurement of corrosive or solvent
gases. For such applications the electronics
are installed in the upper compartment, while
measurement physics are in the lower com-
partment. This separation is also available as
gastight version.
XXF also provides more space e.g. for instal-
lation of optional signal converter elements
for system integrators.
