PREFACE
DANGERDANGER
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 equipment that meets the relevant international and
regional standards. Yokogawa accepts no responsibility for the misuse of this unit.
CAUTIONCAUTION
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 excessively wet.
Do not use an abrasive material or solvent when
cleaning the instrument.
Do not modify the DO202 transmitter.
WARNING
WARNING
Electrostatic charge may cause an explosion hazard. Avoid any actions that cause the generation of
electrostatic charge, e.g., rubbing with a dry cloth.

Safety and Modification Precautions
• Follow the safety precautions in this manual when
using the product to ensure protection and safety
of the human body, the product and the system
containing the product.
Because the enclosure of the Dissolved Oxygen
transmitter Type DO202S-A, -P, -F are made of aluminium, 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.

Introduction 1-3
1-2. Application
The EXA transmitter is intended to be used for continuous on-line measurement in industrial installations.
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 dangerous limits of
a process, to monitor product quality, or to function as a simple controller for a BOD/COD system.
Yokogawa designed the EXA analyzer to withstand harsh environments. The transmitter may be installed
either indoors or outside because the IP65 (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 maintenance
operations.
A variety of EXA hardware is optionally available to allow wall, pipe, or panel mounting. Selecting a proper
installation site will permit ease of operation. Sensors should normally be mounted close to the transmitter
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
box.
The EXA is delivered with a general purpose default setting for programmable items. (Default settings are
listed in 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 sensor used. The EXA
can be adjusted for galvanic and polarographics sensors.
30 metres (100 feet) with a BA10 junction
To record such configuration adjustments, write changes in the space provided in APPENDIX 1 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
systems and a wide range of third-party commercially available probes. For best results, read this manual in
conjunction with the corresponding sensor user’s manual.
Yokogawa designed and built the EXA to meet the CE regulatory standards. The unit meets or exceeds
stringent requirements of EMC Directive 89/336/EEC, to assure the user of continued accurate performance
in even the most demanding industrial installations.

2. GENERAL SPECIFICATIONS
General Specifications 2-1
2-1. Specifications
A. Input specifications
The DO202 accepts output from membrane covered
Dissolved Oxygen sensors. These sensors can be
Galvanic type, where the sensor generates its own
driving voltage or Polarographic type, where the sensor uses external driving voltage from the transmitter.
The input range is 0-50 A for Galvanic sensors and 01 A for Polarographic sensors. For temperature compensation the DO202 accepts Pt1000 (DO30 sensor)
and 22kNTC elements (OXYFERM and OXYGOLD
sensors)
B. Measuring range
- Dissolved Oxygen
: 0 - 50 ppm (mg Oxygen
per kg water);
0 - 1999 ppb (mg Oxygen
per 1000 kg water) and 0
- 600 % Saturation of Air
in Water.
- Temperature : -20 to 150ºC (-4 to 302ºF).
C. Temperature compensation
Automatic using Pt1000 or 22kNTC or
manual Range 0 - 100ºC (32 to 212 ºF)
D. Calibration
Semi-automatic one or two point calibration in air
or in water using solubility tables of ISO 5814.
The influence of pressure and salinity is taken
into account when these specifications are
entered. Also a two point manual calibration is
possible.
E. Transmission Signals
Isolated output of 4-20 mA DC, Burn up (21 mA)
or Burn dwon (3.6 mA when HART® comm. nonused, 3.9 mA when HART comm. used) or pulse
of 21 mA to signal failure.
Note: The transmitter contains a switched
power supply. The transmitter requires a
minimum power voltage in order to work
correctly, which is dependant on the load.

mA-HART® communication
A. Input : Two wire system 4-20 mA
B. Power supply : Nominal 24 volt DC loop powered
DO202G : up to 40 volts
DO202S : up to 31.5 volts
Note: The transmitter contains a switched
power supply, drawing its energy
from the 0-4 mA section of the signal.
Consequently the 17 volt limit is
applied at 4 mA. The characteristic of
the unit is such that above about 7 mA
on the output, the terminal voltage can
drop to 14.5 volts without problem. (see
figure 2-2)
C. Transmission: Isolated output of 4 to 20 mA DC.
D. Signal : Maximum load 425 at 24 VDC.

Associated apparatus connected to the FISCO barrier must not use or generate more
than 250 Vrms or Vdc.
x Resistance between FISCO Intrinsically Safe Ground and earth ground must be less than
1.0 Ohm.
x In case of using cable glands in Outdoor location, they shall be UV rated or made of metal.
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.

General Specifications 2-16
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. Separately
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
(C’ = C’ line/line + 0,5 C’ line/screen if both line are floating)
(C’ = C’ line/line + C’ line/screen if the screen is connected to one line)
Length of spur cable: max. 30 m
Length of trunk cable: max. 1 km
Length of splice : max. 1 m
WARNING
- Substitution of components may impair Intrinsic Safety
- To prevent ignition of flammable or combustible atmospheres, disconnect power
before servicing or read, understand and adhere to the manufacturer’s live
maintenance procedures.
