COMMISSIONING THE
TRANSMITTER

To prepare a Model 3244MV for use with a HART Tri-Loop, you must
configure the transmitter to Burst Command 3, and set the order of the
process variables. In burst mode, the transmitter provides digital
information for the analog current in mA to the Tri- Loop. The Tri-Loop
divides the signal into separate 4–20 mA loops for the primary,
secondary, tertiary, and fourth variables. When using the 3244MV in
conjunction with the Tri-Loop, you must also consider the configuration
of the differential temperature and hot backup features, if used. To
commission a Model 3244MV for use with a HART Tri-Loop, perform
the following procedures.

NOTE

These procedures assume that the sensor and transmitter are
connected, powered, and functioning properly, and that a Model 275
HART Communicator is connected to the transmitter control loop and
is communicating successfully. For information about connecting the
communicator to the transmitter, refer to the Models 3144 and 3244MV
Product Manual, Rosemount publication number 00809-0100-4724.

Set the Transmitter to
Burst Mode

1. From the Home screen, Select

1 Device setup

,

4 Detailed setup

,

3 Output condition

,

2 HART output

,

4 Burst option

to prepare to

set the transmitter to Burst Mode.

The communicator displays the Burst option screen.

2. Select

Process vars/crnt.

The communicator returns to the HART output screen.

3. Select

3 Burst mode

to prepare to enable Burst Mode.

The communicator displays the Burst mode screen.

4. Select

On

to enable burst mode.

The communicator returns to the HART output screen.

5. Select “SEND” to download the new configuration information

to the transmitter.

Set Process Variable
Output Order

1. From the Home screen, select

1 Device setup

,

1 Process variables

,

7 Variable re-map

. Select “OK” to set the control loop to manual.

The communicator displays the Primary Variable screen.

2. Select the item you wish to set as the primary variable at the

“Select PV” prompt.

3. Repeat step 2 for the SV, TV, and QV.

The communicator displays the Variable mapping screen.

4. Select “OK” to accept the order to which the variables are

mapped, or “ABORT” to abort the entire procedure.

NOTE

Take careful note of the process variable output order. You must
configure the Tri-Loop to read the variables in the same order.

5. Select “OK” to return the control loop to automatic control.
