1. INTRODUCTION AND GENERAL DESCRIPTION
TheYokogawaEXAxtISC450Gisaconverter
designed for industrial process monitoring,
measurement and control applications. This
instruction manual contains the information
needed to install, set up, operate and maintain
the unit correctly. This manual also includes a
basic troubleshooting guide to answer typical
user questions.
Yokogawa can not be responsible for the
performance of the EXAxt converter if these
instructions are not followed.
1-1. Instrument check
Upondelivery,unpacktheinstrumentcare-
fully and inspect it to ensure that it was not
damaged during shipment. If damage is found,
retain the original packing materials (including
the outer box) and then immediately notify the
carrier and the relevant Yokogawa sales office.
Make sure the model number on the nameplate
affixed to the top of the instrument agrees with
your order. Example of the nameplate is shown

on the nameplate.
1-2. Application
The EXAxt converter is intended to be used for
continuous on-line measurement of Conductiv-
ity and/or Concentration in industrial instal-
lations. The unit combines simple operation
and microprocessor-based performance with
advanced self-diagnostics and enhanced
communications capability to meet the most
advanced requirements. The measurement
can be used as part of an automated process
control system. It can also be used to indicate
operating limits of a process, to monitor product
quality, or to function as a controller for a dos-
ing/dilution system.
Sensorsshouldnormallybemountedcloseto
the converter in order to ensure easy calibra-
tion and peak performance. If the unit must
bemountedremotelyfromthesensors,WF10
extension cable can be used, up to a maximum
of50metres(150feet),withaBA10junction
box, and up 10 metres standard sensor cable.
The EXAxt is delivered with a general purpose
default setting for programmable items (see
Chapter 5). While this initial configuration
allows easy start-up, the configuration should
be adjusted to suit each particular application.
An example of an adjustable item is the type
of temperature sensor used. The EXAxt can
be adjusted for a number of different types of
temperature sensors.
Details provided in this instruction manual
are sufficient to operate the EXAxt with all
Yokogawa sensor systems and a wide range
of third-party commercially available probes.
Forbestresults,readthismanualinconjunc-
tion with the corresponding sensor instruction
manual.
Yokogawa designed the EXAxt converter to
withstand industrial environments. It meets all
the CE regulatory standards. The unit meets or
exceeds stringent requirements (see section
2) without compromise, to assure the user of
continued accurate performance in even the
most demanding industrial installations.
