Using the transmitter with the HART Tri-Loop

To prepare the 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)
• Tertiary Variable (TV)
• Quaternary Variable (QV)
When using the 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
