HART
Communication Signal:
BRAIN or HART communication signal (superim-
posed on 4 to 20 mA DC signals)
Note: HART is a registered trademark of the HART Com-
munication Foundation.
Conditions of Communication Line:
Supply Voltage: 20.6 to 35 V DC
Load Resistance: 250 to 600 Ω (including cable
resistance)
Refer to Figure 2.
HART Protocol Revision:
HART protocol revision can be selected from 5 or 7
when ordering. (“-J” only)
The protocol revision can be changed by user con-
figuration.
The HART protocol revision at the time of shipment
is shown by the last number at the serial number
column of the name plate.
Note: Protocol revision supported by HART configuration
tool must be the same or higher than that of AXR.

Indicator (*2):
Full dot-matrix LCD (128 x 64 pixels)
Operational switch: 4 magnet switches (including
push switches)
Lightning Protector:
When optional code A is selected, the lightning pro-
tector is built into the power supply and digital output
terminals.
Protection:
General-purpose Use/TIIS Flameproof type:
IP66/IP67, NEMA Type 4X
Explosion proof type except for TIIS:
In the case of explosion proof type except TIIS,
refer to description of “Enclosure” in “HAZARDOUS
AREA CLASSIFICATION”.
Converter Coating:
Case and Cover: Corrosion-resistant coating
Coating Color: Mint-green paint (Munsell 5.6 BG
3.3/2.9 or its equivalent)
Converter Material:
Case and Cover: Aluminum alloy
Mounting/Shapes:
• Electrical Connection: ANSI 1/2 NPT female
ISO M20 x 1.5 female
JIS G1/2 (PF1/2) female
• Direction of Electrical Connection: The direction can
be changed even after delivery.
• Terminal Connection: M4 size screw terminal
Grounding:
Grounding resistance of 100 Ω or less is necessary.
When the optional code A is selected, grounding
resistance of 10 Ω or less shall be required.
* This also applies to TIIS explosion proof types.
* For an explosion proof type except for TIIS, follow
the domestic electrical requirements in each coun-
try.
Functions
How to Set Parameters (*2):
Both of four push buttons and magnet switches can
be used for setting. The magnet switches can be
used to set parameters without opening the case
cover.
The magnet switches need operational magnets
(optional code BM). These are also available as part
number F9840PA.
Users can choose a language on indicator from Eng-
lish, Japanese, German, French, Italian, and Span-
ish. Parameters can also be set with the configuration
tool (Such as HHT (handheld terminal) or FieldMate,
etc.). The language for the HHT is English only.
Instantaneous Flow Rate/Totalized Value Display
Functions (for models with an indicator) (*2):
The full dot-matrix LCD enables user selections of
displays from one line to three lines for:
• Instantaneous flow rate
• Instantaneous flow rate (%)
• Instantaneous flow rate (bar graph)
• Current output value (mA)
• Totalized forward-direction flow rate
• Totalized reverse-direction flow rate
• Totalized differential flow rate
• Tag No.
• Results of electrode adhesion diagnosis
• Communication type
