INTRODUCTION
Thank you for choosing the BT200 BRAIN TERMI-
NAL.
This user’s manual describes how to operate the model
BT200-N00 BRAIN TERMINAL and the model
BT200-P00 BRAIN TERMINAL with printer, and
presents cautionary notes on usage. The contents
display on the BT200 and the items that can be set by
the BT200 depend on the types of instruments used
with the BT200. Please read this manual before using
the instrument.
Note that changes in the specifications, construction, or
component parts of the BT200 may not be reflected in
this manual at the time the changes are made, provided
that postponement of revisions will adversely affect
functional or performance. Please keep the above in
mind when using this manual.
If a problem arises, please inform us of the nature of
the problem and the circumstances under which it
developed, including the model (MODEL),
specification and optional codes (SUFFIX), serial
number (NO.) from the data plate (Figure 2.2). Any
diagrams, data and other information you can include
in your communication will be helpful.
Yokogawa cannot take responsibility for any loss of
instrument function that results from repair undertaken
independently by the customer.
In case of problems, contact the Yokogawa
representative from which the instrument was
purchased, or the nearest Yokogawa office.

1. PRECAUTIONS
1.1 CHECK THE CONTENTS OF
THE PACKAGE
The BT200 BRAIN TERMINAL are thoroughly tested
at the factory before shipment. When the BT200 units
are delivered, visually check to make sure that no
damage occurred during shipment. Also check that the
specifications are as specified in the purchase order by
comparing those with the Model and Specification
Codes in section 2.2
Figure 1.1 BT200

<Toc> <Ind> <1. PRECAUTIONS>
IM 01C00A11-01E
1.2 PRECAUTIONS IN HANDLING
(1) WHERE TO STORE
Store the unit in places meeting the following
conditions:
•Places not exposed to rain or water.
•Ambient storage conditions
Ambient temperature: -15 to 60°C (5 to 140°F)
Ambient humidity:
BT200-N00 ... 5 to 95%RH at 40°C (104°F)
(free from condensation)
BT200-P00 .... 30 to 80%RH at 40°C (104°F)
(free from condensation)
(2) HANDLING NOTES
a. Working temperature and humidity ranges
BT200-N00
Ambient temperature: -15 to 55°C (5 to 131°F)
Ambient humidity: 5 to 95%RH at 40°C (104°F)
(free from condensation)
BT200-P00
Ambient temperature: 0 to 50°C (32 to 122°F)
Ambient humidity: 30 to 85%RH at 40°C (104°F)
(free from condensation)
•Do not leave the unit exposed to direct sunlight
for an extended period of time.
•The LCD (liquid crystal display) may appear
dark or the unit may be disabled due to loss of
the battery capacity at ambient temperatures
below -15°C. (5°F)
b. The unit is not waterproof.
Cover the unit against water when using it
outdoors while it is raining.
Do not allow the unit to fall into water.
c. Note on using a transceiver
While the unit and the associated equipment are
fully protected against high-frequency noise
interferences, a transceiver used near the unit and
the associated equipment or near their cables could
impart high-frequency noise interferences to them.
When using a transceiver for the first time, check
its possible effects on the transmission loop by
bringing it closer to the unit, starting at a point
several meters away, to locate the range of safety.

<Toc> <Ind> <1. PRECAUTIONS> 1-3
IM 01C00A11-01E
d. Following communication is not permitted as it
may result communication error or indication
error:
✽Connecting more than two BRAIN Terminals to
one BRAIN instrument simultaneously.
✽Simultaneous communication by BRAIN
Terminal and DCS.
(3) POWER SUPPLY
a. Note on using dry batteries
•The BT200 model on a standard configuration
comes complete with five alkali batteries. The
unit as shipped, however, is not loaded with
these batteries. Before starting to use the BT200,
load the batteries shipped under the same cover
as instructed in Section 6.1, “Replacing Batter-
ies.”
•Use batteries of a specified voltage (1.5V).
•To avoid possible leaks, remove batteries from
the unit before leaving it out of service for an
extended period of time.
•In the case of the model with printer, printed
characters may become faint when batteries
except alkali type are used.
b. Duration of continuous operation
•When running the unit from alkali batteries: 50
hours least (if the printer is not used).
•If the printer is used, the duration of continuous
operation is reduced according to the rate of
printout (about 10 hours/1,000 lines).
c. Low-voltage indicator
•The BT200 turns on its BATTERY indicator
when the battery voltage falls. Replace the
batteries whenever the BATTERY indicator is on.
d. Autopower-off feature
•The BT200 will switch itself off automatically
when no key access is made for five minutes or
longer.
(4) CAUTION for INTRINSICALLY SAFE TYPE
•Please make sure to refer to “APPENDIX B” for
Intrinsically Safe Type.
•Intrinsically Safe type can not be modified to
equip optional printer afterward.
•Intrinsically Safe Type can not communicate by
using communication cable with 5-pin connector.
•Please use the specified baterry for Intrinsically
Safe Type.

2. INTRODUCTION TO
BT200
The BT200 BRAIN TERMINAL is a portable terminal
used in a 4 to 20 mA DC signal line connected to a
BRAIN instrument (*1).
The 4 to 20 mA DC signal line between the BT200
and the BRAIN instrument can be superimposed with a
communication signal to achieve two-way communica-
tion.
Working as a master, the BT200 Permits:
1. Setting and changing parameters for the BRAIN
instrument
2. Monitoring PV and MV values and self-check
information on the BRAIN instrument, and
3. Directing the BRAIN instrument to enter the
constant current output mode.
(*1) BRAIN instrument
Any instrument in support of BRAIN communi-
cations, including field instruments, such as
differential pressure and pressure transmitters,
vortex flow meters, magnetic flow meters and
temperature transmitters, and CENTUM signal
conditioners (SC).

INTO THE BT200
When plugging the dedicated communication cable
into the BT200, adjust the up arrow mark on the
cable to the
●
mark on the BT200 connector and
push the cable into position until a click sounds.
Note: You cannot plug the connector cable for the BT100 into
the BT200, because the BT200 and BT100 have different
connector structures.

3.2 CONNECTION WITH BRAIN
SERIES INSTRUMENTS
(1) CONNECTION IN THE INSTRUMENT
TERMINAL BOXES
Some Brain Series equipment terminal boxes
have pins for connection to the BRAIN
TERMINAL. When connecting the BRAIN
TERMINAL to Brain Series equipment in the
field, connect as shown in Figure 3.2.a using
the BRAIN TERMINAL cable with IC clips.
Polarities are marked on the terminal box pins
and on the BRAIN TERMINAL
cable; however, no damage will occur if they
are connected with reverse polarity.
(2) CONNECTION IN RELAY TERMINAL
BLOCK
There are no dedicated pins for connecting to
the BRAIN TERMINAL in the field relay
terminal block or in the meter compartment
terminal block. In this case, use the cable with
the alligator clips.

(3) CONNECTION TO SIGNAL CONDITIONER
ESC (signal conditioner communication card) or
EXT (extension card) is provided with a BRAIN
TERMINAL connector (see Figure 3.2.b).
A 5-pin connector cable for the BRAIN TERMI-
NAL is supplied when the BRAIN TERMINAL
comes with /C1 options. This cable is also
available at extra cost.
