1.5 X-STREAM X2GK: ½19 Inch Table-Top Unit
1.5 X-STREAM X2GK
This compact model for general purposes
can be tted with up to three measurement
channels in various combinations. Power is
supplied by an internal wide range power sup-
ply or a separate external power supply unit.
By default the units are congured for tabletop
use. A carrying handle is optional available
which makes it easy to take the instrument to
varying sampling points. For rack mounting a
X2GK is xed by screws located at the front
panel.
Front panel
The analyzer’s front panel consists of one
4x20-character alphanumeric LCD display, a
membrane keyboard and three status LEDs
(Fig. 1-4). The colors of the LEDs are based on
the NAMUR NE 44 specications. The LEDs
are activated according to the NE 107 stan-
dards and correspond to the following status
messages: “Failure”, “Function check”, “Out of
specication” and “Maintenance request”.
Connection to power supply
AC is supplied by an IEC chassis plug with
power switch and fuse holders. The internal
wide range power supply unit enables the
analyzers to be used worldwide. DC 24 V
power is supplied via a 3-pin socket at the
rear of the unit.
Interfaces
The electrical connections for interface sig-
nals are provided via submin-D connectors,
also mounted at the back of the unit (Fig. 1-4).
For applications where screw-type terminals
are preferred for connecting signal wires, op-
tional adapters are available, which are moun-
ted directly onto the submin-D connectors.
Interface signals
The number of connections varies according
to the number of interfaces installed: a 25-
pin submin-D socket terminal strip is always
included, providing one analog output (4-20
or 0-20 mA) and the contacts for the four
NAMUR status relays.
Further analog outputs can also be provided,
e.g. to provide a measurement signal at dif-
ferent resolutions. A maximum of four analog
outputs are possible.
A serial Modbus interface can also be installed
on request (RS 232 or RS 485 with Modbus
RTU protocol, via 9-pin submin-D male con-
nector
); alternatively an RJ45 socket can also
give access to Ethernet-Modbus-TCP.
Digital inputs and outputs can be used to
control analyzer functions and external
components. The 7 inputs and 9 outputs are
connected to peripheral devices via a 37-pole
submin-D socket terminal strip.
Detailed technical details on the various inter-
faces can be found in
1.3, page 1-9. The
conguration of the connectors are described
in chapter 4 “Installation” and the soft-
ware settings in chapter 6 “Software”.
A further submin-D socket, which is not in
detail described in this manual, is also located
at the rear of the unit, and is designated as a
Service Interface.
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.
