2.13 Using the transmitter with the HART Tri-Loop
To prepare the Rosemount 644 Transmitter with dual-sensor option for use with a Rosemount 333 HART
Tri-Loop, the transmitter must be configured to Burst Mode and the process variable output order must
be set. In Burst Mode, the transmitter provides digital information for the four process variables to the
HART Tri-Loop. The HART Tri-Loop divides the signal into separate 4–20 mA loops for up to three of the
following choices:
Primary Variable (PV)
Secondary Variable (SV)
Ter tiary Variable (TV)
Quaternary Variable (QV)
When using the Rosemount 644 Transmitter with dual-sensor option in conjunction with the HART
Tri-Loop, consider the configuration of the differential, average, first good temperatures, Sensor Drift
Alert, and Hot Backup features (if applicable).
Note
The procedures are to be used when the sensors and transmitters are connected, powered, and
functioning properly. Also, Field Communicator must be connected and communicating to the
transmitter control loop. For communicator usage instructions, see “Field Communicator” on page 9.
