Basic Configuration/Start-Up
5. Set the Rosemount 3300 Series in Burst Mode.
HART command [1, 4, 5, 2, 3].
RCT: Device Commands > Details > Set Burst Mode option.
6. Select Burst option 3 = Process variables and current (Process vars/crnt).
HART command [1,4,5,2,4].
7. Install the Tri-Loop. Connect Channel 1 wires, and optionally wires for Channel 2 and
Channel 3.
8. Configure Tri-Loop Channel 1:
a. Assign variable: Tri-Loop HART command [1,2,2,1,1].
Make sure the SV, TV, and QV match the configuration of the Rosemount 3300
Series Transmitter.
b. Assign units: Tri-Loop HART command [1,2,2,1,2]. Make sure the same units are
used as for the Rosemount 3300 Series Transmitter.
c. Set the Upper Range Value and the Lower Range Value: Tri-Loop HART command
[1,2,2,1,3-4].
d. Enable the channel. Tri-Loop HART command [1,2,2,1,5].
9. (Optional) Repeat steps a-d for Channels 2 and 3.
10. Connect wires to Tri-Loop Burst Input.
11. Enter the desired tag, descriptor, and message information:
Tri-Loop HART command [1,2,3].
12. (Optional) If necessary, perform an analog output trim for Channel 1 (and Channel 2
and 3 if they are used).
Tri-Loop HART command [1,1,4].
