Security and password access

Access to the transmitter via the NFC interface requires the use
of an authentication password. The NFC interface supports
two access accounts, each with a separate password. There is
one user account for normal use and an account to reset the
user account passwords.
Enter the account authentication password in the Velox phone/
tablet productivity app before bringing the configuration
device into contact with the transmitter. Data exchange will not
be successful if an incorrect password is used.
IMPORTANT (NOTE)
Password and PIN details are entered via the Setting
option in the Instrument List pane – refer to page
48 for navigation details.
User account 1 to 3 – standard level privileges
Factory default password: am2k
These are the main user account for general access to the
transmitter and has a user-settable password.
Process values, user configuration settings, transmitter
diagnostics conditions and logger data are accessible with the
standard level privileges provided by the User account.
All configuration changes made to the device FEX45X are
recorded and maintained in the audit log, the date and time are
stamped with the identity of the user account used to make the
configuration changes. Such information can be exported from
the Audit Log Retrieve feature.
IMPORTANT (NOTE)
For FEX45X, the 2nd and 3rd User accounts are
disabled by default.
These are the only items that users generally require and are
expected to know during normal flow meter use. Advanced
settings and factory-specific configuration (not needed to for
normal flowmeter configuration and control) are accessible only
with high levels of access privilege. Temporary elevated access
privileges can be obtained only with a meter specific one-time
use command generated by ABB technical support and service
teams.
IMPORTANT (NOTES)
• It is strongly recommended that the account's
factory default authentication password is changed
from the factory default on commissioning the
flowmeter.
• When changing a password, record it somewhere
secure, especially if each flowmeter has a unique
password. If a password is lost or unknown, it must
be reset to the factory default password using a
single-use hash code that is specific to the
applicable meter. This will reset the flowmeter to
the factory default settings and allow access to it.
Contact your ABB technical support or service engineer for help
if you need access to advanced settings or factory
configuration. (Note, more data is exchanged via the NFC
connection with higher levels of access so it takes longer to
read from the flowmeter when these privileges are being
granted.)
IMPORTANT (NOTE)
The command code/single-use hash code is specific
to the applicable meter and generated by ABB
technical support/service teams only. Contact your
regular ABB technical support or service engineer for
help if you need to reset the user account password.
