2. Operating the VFM 3100
2.1 Introduction
Communication with the VFM 3100 is carried out using the HART
Model 275 Communicator or the optional Local Digital Display/Con-
figurator. General instructions for using the HART Configurator can
be found in MAN 4250, HART Communicator Product Manual.
Vortex-specific instructions for using the HART configurator will be
found in chapter 8 of this document. Complete instructions for using
the Local Configurator will be found in chapter 9.
Note: For proper communication with VFM 3100, the HART
configurator must contain the DD for the KROHNE VFM 3100.
This DD is available from KROHNE, or any other authorized HART
Foundation source.
2.2 Passwords
The transmitter itself has no password. Rather, security measures,
i.e., the ability to access functions such as calibration, configuration,
and testing, are associated with the configurators used to communi-
cate with the transmitter. The HART Communicator has no security
measure other than access to the device itself. The Local Digital Dis-
play/Configurator requires a password that is user definable. See
chapter 9.
2.3 Configuration Database
In order to function, the transmitter requires specific embedded
information, termed the “configuration database”. The parameters in
this database are listed in Table 8, and defined in chapter 9.
Each VFM 3100 is shipped from the factory with an operating confi-
guration database; however, the VFM 3100 will not provide an accu-
rate measurement if the configuration does not fit the application.
Be sure to check the configuration of each VFM 3100 prior
to start-up!
