Operation
NOTE
• Before using FN310, connect FN110. For
detail on how to install the FN110, refer to
subsection 4.2.1 “Installation of FN110”.
• It is required to set security and network
information to enable this product to be
connected to the field wireless network.
For more details, refer to subsection 6.3
“Connecting to the Field Wireless Network”.
1) Setting the HART Device
Set the parameters of the HART device as
shown in Table 6.1. Refer to the user manual of
the HART device for the setting method.
2) Checking Installation and Wiring
Ensure that the FN310, FN110 and the HART
device are installed correctly according to the
procedures described in section 4 “Installation”,
and section 5 “Wiring”.
3) Connecting to the Field Wireless Network
Insert batteries into the battery case, and install
to the FN310. For details of installation of
battery, refer to subsection 8.3 “Replacing the
Battery Pack” and subsection 8.4 “Replacing
the Batteries”.
Provisioning is to set the security and network
information. For details of provisioning, refer to
section 6.3 “Connecting to the Field Wireless
Network”.
4) Checking parameter of the FN310 and the
HART device
Use the device configuration tool and confirm
that the HART device and the FN310 operate
properly. Check parameter values or change
the setpoints as necessary.
The integral indicator can be used to confirm
that this product is operating properly.
For details on how to confirm this, refer to
subsection 7.4 “Self-Diagnostics”. ISA100
devices display self-diagnostic information
in an easy-to-understand manner using four
categories (Function check, Maintenance
required, Failure, and Out of specification)
according to NAMUR NE107*
* NAMUR NE107 “Self-Monitoring and Diagnosis of Field
Devices”
Confirm operation status by integral indicator
If the FN310 is faulty, an error code is displayed.

Integral Indicator with Error Code
NOTE
If any of the above errors are indicated on the
display of the integral indicator or the device
configuration tool, refer to subsection 8.10.3
“Errors and Countermeasures” for the corrective
action.
Verify and Change HART Device Setting and
Values
Table 6.1 lists the required configuration for the
HART device. These parameters must be set
before connecting the HART device to the FN310.
Refer to the HART device User’s Manual for how to
set the parameters.

NOTE
When HART device is connected as One-to-one
connection, be sure the following precautions.
• Change the output settings of the HART
device before connection as follows.
• 4 mA in a normal operation.
• 3.6 mA or less when sensor failure.
• When the HART device is connected to
the VOUT terminal, the FN310 changes it’s
HART Polling Address automatically. If the
HART Polling Address of the HART device is
0, the FN310 changes it to 1.
