1. Introduction

Thank you for purchasing the DPharp EJX series

pressure transmitter/EJA series pressure

transmitter (“transmitter”).

The transmitters are precisely calibrated at the

factory before shipment. To ensure both safety and

e󰀩ciency,pleasereadthismanualcarefullybefore

operating the instrument.

This manual describes the BRAIN protocol

communication functions of the transmitter and

explains how to set the parameters for the

transmitters using the BT200 handheld terminal.

For information on the installation, wiring, and

maintenance of the transmitters, please refer to the

user’s manual of each model.

WARNING

When using the transmitters in a Safety

Instrumented System application, refer to the

Functional Safety Manual (Document No.:

TI 01C25A05-01EN or TI 01C25A05-21EN for

option code SLT) and follow the instructions and

procedures described there.The document can

be downloaded from the website of Yokogawa.

(Website address:

https://www.yokogawa.com/solutions/products-

platforms/eld-instruments/)

In order to satisfy the requirement of Safety

Instrumented System, executing parameters

setting is required. Please refer to 3.2 “Setting

Parameters Using the BT200” for setting range.

Please also refer to the status output setting in

the same clause. After installing the transmitter,

1.1 Safe Use of This Product

For the safety of the operator and to protect the

instrument and the system, please be sure to follow

this manual’s safety instructions when handling this

instrument. If these instructions are not heeded,

the protection provided by this instrument may be

impaired. In this case, Yokogawa cannot guarantee

that the instrument can be safely operated. Please

pay special attention to the following points:

(a) Installation

• This instrument may only be installed by an

engineer or technician who has an expert

knowledge of this device. Operators are not

allowed to carry out installation unless they

meet this condition.

• With high process temperatures, care must

be taken not to burn yourself by touching the

instrument or its casing.

• Never loosen the process connector nuts when

the instrument is installed in a process. This can

lead to a sudden, explosive release of process

uids.

• When draining condensate from the pressure

detector section, take appropriate precautions

to prevent the inhalation of harmful vapors and

thecontactoftoxicprocessuidswiththeskin

or eyes.

• When removing the instrument from a

hazardous process, avoid contact with the

processuidandtheinteriorofthemeter.

• All installation shall comply with local installation

requirements and the local electrical code.

(b) Wiring

• The instrument must be installed by an

engineer or technician who has an expert

knowledge of this instrument. Operators are not

• Wait10min.afterthepoweristurnedo󰀨,before

opening the covers.

(d) Maintenance

• Please carry out only the maintenance

procedures described in this manual. If you

require further assistance, please contact the

nearestYokogawao󰀩ce.

• Care should be taken to prevent the build up of

dust or other materials on the display glass and

the name plate. To clean these surfaces, use a

soft, dry cloth.

(e) Modication

• Yokogawa will not be liable for malfunctions or

damageresultingfromanymodicationmade

<2. Connection> 2-1

IM 01C25T03-01E

2. Connection

The BRAIN communication signal is superimposed

onto the 4 to 20 mA DC analog signal. Since

the modulated wave is a communication signal,

superimposing it on the normal signal will,

from basic principles, cause no error in the DC

component of the analog signal. Thus, monitoring

can be performed via the BT200 while the

transmitter is on-line.

2.1 Connecting the BT200

IMPORTANT

Analog output may change temporally in

connecting with BRAIN terminal due to an initial

currentowedtoit.Topreventcommunication

signala󰀨ectingtheuppersystem,itis

recommendedtoinstallalow-passlter

(approximately 0.1s)

Connection to the transmitter with the BT200

can be made by either connecting to the BT200

connection hooks in the transmitter terminal box or

by connecting to a relaying terminal or a terminal

board.

When Powering On

For models with the integral indicator code “D”, the

display shows all segments in the LCD and then

changes to the displays shown below sequentially.

All segments display Model name (3 s)

NOTE

For output signal code “D”, this function is

available for software revision 2.02 or later.

Software revision can be checked by the

parameter M15: SOFT REV.

Refer to section 3 “Operation” how to call up the

parameter.

NOTE

LCD display can be set to all segments display

only by the parameter I41: POWER ON INF.

ON Show All segments display, Model name and

Communication Protocol when powering on.

OFF Show All segments display when powering on.

Refer to section 3 “Operation” how to call up the

parameter.

<3. Operation>3-1

IM 01C25T03-01E

3. Operation

The transmitter is equipped with BRAIN

communications capabilities, so that range

changes, Tag No. setup, monitoring of self-

diagnostic results, and zero point adjustment

can be handled remotely via the BT200 BRAIN

TERMINAL, the FieldMate Versatile Device

Management Wizard or the CENTUM CS

console. This section describes procedures for

setting parameters using the BT200. For further

information on the BT200, see the BT200 User’s

Manual (IM 01C00A11-01E).

IMPORTANT

Communication signal is superimposed on

analog output signal. It is recommended to set

alow-passlter(approximately0.1s)tothe

receiverinordertoreducetheoutpute󰀨ect
