SPECIAL FUNCTIONS
TriLoop The Rosemount 333 HART Tri-Loop HART-to-Analog Signal Converter is
capable of converting a digital HART burst signal into three additional 4-20
mA analog signals.
To set the Rosemount 3300 transmitter up for the HART Tri-Loop do the
following:
1. Make sure that the 3300 transmitter is properly configured.
2. If RCT is used for the 3300 setup, it is recommended that the Receive
Buffer and Transfer Buffer for the selected COM port are adjusted as
described below in section “To set the COM port buffers.” Otherwise the
Burst Mode can not be turned off by RCT (for further information on other
options for turning off the Burst Mode see “To turn off the Burst Mode.”
3. Assign transmitter variables Primary Variable, Secondary Variable etc.
HART command [1,1,1,1].
RCT: Setup>Output tab.
4. Configure variable units: Length, Volume and Temperature.
HART command [1,3,2,1-3].
