The following models, HART protocol revisions and
conguration les are applied in this manual.

In order to classify multiple models, HART protocol
revisions, or conguration les, abbreviated words
or marks are used as below in this manual.
■Appliedmodels
• The following expression is used instead of
model name.
[Model: EJAE]
EJA series or EJA
[Model: EJXA (excluding EJX9A)]
EJX series or EJX
•
EJX
mark indicates specication or function
applied for EJX series only.
■ HART protocol revision
• Two HART protocol revisions are expressed for
short as below.
HART protocol revision 5: HART 5
HART protocol revision 7: HART 7
•
HART 7
mark indicates specication or function
applied for HART 7 only.
Refer to section 2.2 for typical functions for
HART 7.
•
HART 5
mark indicates specication or function
applied for HART 5 only.
■ Output signal
This instruction manual covers both 4 to 20 mA
DC output (Output signal code J) and 1 to 5 V DC
output (Output signal code Q) with HART 7.
• Two analog output signal type may be
expressed for short as below.
4 to 20 mA DC output: 4-20mA
1 to 5 V DC output: 1-5V
•
4-20mA
mark indicates the specication or
function applied for 4 to 20mA only.
• Unless otherwise stated or shown by a mark,
the functions described in the chapter 3 are
applicable for both 4 to 20 mA and 1 to 5 V
output types. Even though, the description may
only show the values for 4 to 20 mA output. For
1 to 5 V output, replace the current mA value
with corresponding voltage V value, with using
the following table.

■ Conguration le
Three conguration les are applied in this
manual.
• DD stands for Device Description (le).
• This manual covers two revision DTM (Device
Type Manager) les based on FDT (Field
Device Tool) standard. The di󰀨erence of
revisions is indicated as follows.
[DTM for FDT 1.2]
DTM (FDT1.2) or [1.2]
[DTM for FDT2.0]
DTM (FDT2.0) or [2.0]
The root referring to a parameter is classied to
Group I or II according to applied conguration le.

As the above, two roots referring to a parameter is
shown in this manual.
