PREFACE

Electric discharge
The EXA analyzer contains devices that can be
damaged by electrostatic discharge. When servicing
this equipment, please observe proper procedures
to prevent such damage. Replacement components
should be shipped in conductive packaging. Repair
work should be done at grounded workstations using
grounded soldering irons and wrist straps to avoid
electrostatic discharge.
Installation and wiring
The EXA analyzer should only be used with equip-
ment that meets the relevant international and
regional standards. Yokogawa accepts no responsi-
bility for the misuse of this unit.
The instrument is packed carefully with shock
absorbing materials, nevertheless, the instrument
may be damaged or broken if subjected to strong
shock, such as if the instrument is dropped. Handle
with care.
Although the instrument has a weatherproof
construction, the transmitter can be harmed if it
becomes submerged in water or becomes exces-
sively wet.
Do not use an abrasive material or solvent when
cleaning the instrument.
Do not modify the ISC202 transmitter.
Electrostatic charge may cause an explosion hazard.
Avoid any actions that cause the generation of elec-
trostatic charge, e.g., rubbing with a dry cloth.
Warning label
Because the enclosure of the Dissolved Oxygen
transmitter Type ISC202S-A, -P, -F are made of alu-
minium, if it is mounted in an area where the use of
category 1 G Zone 0 apparatus is required, it must
be installed such, that, even in the event of rare
incidents, ignition sources due to impact and friction
sparks are excluded.

1-1. Instrument check

Upon delivery, unpack the instrument carefully 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 textplate affixed to the side of the instrument agrees with your
order. Examples of nameplates are shown below.

Introduction 1-3

1-2. Application

The EXA transmitter is intended to be used for continuous on-line measurement in industrial installa-
tions. 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 indi-
cate dangerous limits of a process, to monitor product quality, or to function as a simple controller for a
dosing/neutralization system.
Yokogawa designed the EXA transmitter to withstand harsh environments. The transmitter may be
installed
either indoors or outside because the IP65 and NEMA 4X housing and cabling glands ensure the unit is
adequately protected. The flexible polycarbonate window on the front door of the EXA allows pushbutton
access to the keypad, thus preserving the water and dust protection of the unit even during routine main-
tenance operations.
A variety of EXA hardware is optionally available to allow wall, pipe, or panel mounting. Selecting a prop-
er installation site will permit ease of operation. Sensors should normally be mounted close to the trans-
mitter in order to ensure easy calibration 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 mtr (150 feet) with a BA10
junction box.
The EXA is delivered with a general purpose default setting for programmable items. (Default settings
are listed in Section 5 and again in Chapter 11). 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 EXA can be adjusted for two different types of temperature
sensors.
To record such configuration adjustments, write changes in the space provided in Chapter 11 of this
manual. Because the EXA is suitable for use as a monitor, a controller or an alarm instrument, program
configuration possibilities are numerous.
Details provided in this user’s manual are sufficient to operate the EXA with all Yokogawa sensor

x The FISCO concept allows the interconnection of several I.S. apparatus not specifically
examined in such combination. The criterion for such interconnection is that the voltage
(Vmax), the current (Imax) and the power (Pi) which I.S. apparatus can receive and remain
intrinsically safe, considering faults, must be equal to or greater that the voltage (Voc, Vt),
the current (Ioc, It) and the power (Poc, Pt) which can be provided by the FM approved
FISCO barrier. In addition, the maximum unprotected residual capacitance (Ci) and
inductance (Li) of each apparatus (other than the terminator) connected to the Fieldbus
must be less than or equal to 5nF and 10 H respectively.
Specifications 2-17
x In each I.S. Fieldbus segment only one active source, normally the FM Approved FISCO
barrier, is allowed to provide the necessary power for the Fieldbus system. All other
equipment connected to the bus cable has to be passive (not providing energy to the
system), except to a leakage current of 50A for each connected device. Seperately
powered equipment needs a galvanic isolation to insure that the I.S. Fieldbus circuit
remains passive.
x The cable used to interconnect the devices needs to comply with the following
parameters:
Loop resistance R’: 15 … 150 /km; Inductance per unit length L’: 0.4 … 1 mH/km
Capacitance per unit length C’: 80 … 200 nF/km
