1.8 X-STREAM X2FD
1.8 X-STREAM X2FD: Cast Aluminum Flameproof Housing
The most obvious X-STREAM 2FD analyzer
feature is its ameproof housing (Fig. 1-10).
This enables its use in Ex-zone 1 hazardous
environments. With its protection type of IP66/
NEMA 4X and sturdy cast aluminum housing
designed for wall-mounting, it can also be
used in other tough environments.
IPx6: In case of occasional ooding, e.g.
heavy seas, water shall not enter in harmful
quantities
IP6x: Protection against penetration by dust.
Live or internal moving parts are completely
protected.
Up to four measuring channels in any com-
bination can be installed in the X-STREAM
X2FD. Optionally, a cover can be installed
over the physical components. This separa-
te volume can be heated up to a maximum
temperature of 60 °C to minimize the effects
of changes in external temperature.
A description of the different piping options is
given in
section 1.2.6, page 1-5.
Front panel
The front panel is physically protected with
a safety glass panel and consists of a 4x20-
character alphanumeric LC display, a keypad
and 3 status LEDs (Fig. 1-11). The colors of
the LEDs are based on the NAMUR NE 44
specications
. The LEDs are activated in line
with NE 107 standards and indicate “Failure”,
“Function check”, “Out of specication” and
“Maintenance request”.
Instead of the LCD
display, a vacuum uorescent display can
be tted.
Electrical connections
Electrical connections are made via internal
screw-type terminals; the corresponding
cables are fed through cable inlets on the
underside of the unit into the housing (Fig.
1-12). The front of the unit opens downwards
once the screws located on the surrounding
ange are removed
.
Power supply
Mains power is connected via screw-type
terminals with integrated fuses, located in
the front right-hand area of the housing. The
internally mounted wide range power sup-
ply unit ensures the analyzers can be used
worldwide.
Interface signals
In the basic conguration, the unit has 36
internal screw-type terminals for interface
signals, providing one analog output (4–20 or
0–20 mA) for each channel and the contacts
for the four NAMUR status relays. Further
