Using the HARTR Tri‐Loop™ HART‐to‐Analog
™
Signal Converter with Fisher
FIELDVUE™ Digital
Valve Controllers
Tri‐Loop Signal Converter Operation with FIELDVUE Digital Valve
Controllers
The Rosemount™ 333U (alarm high) and 333D (alarm low) HART Tri‐Loop HART‐to‐Analog Signal Converter is used to
read values from the digital valve controller and present them as 4 to 20 mA signals accessible to AI channels on
traditional host systems. This device accepts a HART burst command 3 from a smart instrument and converts it into up
to three 4 to 20 mA analog output signals. The output signals then can be read by a control system's analog input
channels. Refer to the appropriate HART Field Device Specification instruction manual supplement for command 3
variables (see Related Fisher Documents on page 2).
Figure 1 shows a typical installation of the Tri‐Loop signal converter with a digital valve controller.
The Tri‐Loop signal converter may be used with the following FIELDVUE digital valve controllers:
D DVC6200 or DVC6000 HW2 digital valve controllers
Note
Burst mode communication is not supported with HART 7 in firmware revisions 2-6.
D DVC2000 digital valve controllers
D DVC6000 digital valve controllers
The Tri‐Loop signal converter outputs will go to their fail state when any of the following occur:
D there is a loss of burst mode communication from the smart instrument or
D there is a device malfunction reported by the smart instrument.
Loss of power to channel 1 will cause all channels to go to no output. Loss of power to either channel 2 or 3 will not
affect the remaining channels.
When in its fail state, a 333U signal converter generates a current of 21.75 mA or greater. A 333D generates a fail state
current which is less than 3.75 mA.
The Tri‐Loop signal converter is not recommended for FIELDVUE digital valve controller in split-range applications.

Installation Considerations
The Tri‐Loop HART‐to‐analog signal converter design allows three different din‐rail mounting options:
D Asymmetrical 32mm G rail
D Symmetrical 35 x 7.5 mm top hat rail
D Symmetrical 35 x 15 mm top hat rail
As shown in figure 1, the signal converter must be installed on the safe side of an Intrinsic Safety (IS) barrier. It is
approved for FM and CSA ordinary location, and bears the CE marking to indicate compliance with applicable EC
directives. It is not approved nor designed for nuclear‐qualified applications.
Figure 1 also shows a HART filter as a convenient connection point for the two additional connections to the loop
wires. The necessity of a HART filter depends upon the control system; the Tri‐Loop signal converter does not add a
requirement for a filter. If a filter is required, the HF340 din rail mount filter provides a convenient method for
connecting field wiring between the control system, the signal converter and the digital valve controller. If no filter is
required, the HF341 is available without filter action (straight‐through).

Tri‐Loop Signal Converter Configuration From Fisher
The Tri‐Loop HART‐to‐analog signal converter ships from Fisher pre‐configured with one of the choices listed in table
1. As shown in the table the unit is available with either a high or low fail state. The channel 1 variable is always travel
and the channel 2 variable is always travel target. Channel 3 is disabled, but can be configured by the user, using a Trex
Device Communicator, a 475 Field Communicator, or AMS Suite: Intelligent Device Manager.

CHANNEL
TRI‐LOOP MODEL FAIL STATE
333D Low
333U High
1. Configurations of channels are preset, but can be changed with the HART or Field Communicator, or AMS Device Manager.
The burst message from FIELDVUE digital valve controllers configured for fail‐open actuators associates 0% travel with
an open valve. Therefore, channel 1 of the Tri‐Loop should be configured to provide a 20 mA output when the valve is
open and a 4 mA output when the valve is closed (range is 100 to 0 rather than 0 to 100).

Power Source
Each output channel on the signal converter connects to a separate control system analog input channel. Each channel
operates on a terminal voltage of 11 to 42.4 VDC. The signal converter is powered from the channel 1 power source.
Enabling Burst Mode
For a FIELDVUE digital valve controller to communicate with the Tri‐Loop signal converter, the burst mode must be
enabled. You can use a Field Communicator, ValveLink software, or AMS Device Manager to enable burst mode in the
digital valve controller.
Note
The path to access Burst varies depending on the DD revision of the digital valve controller. Refer to the appropriate instruction
manual to verify path.
Note
HART devices connected to an instrument which is actively using burst mode communication may experience some HART
communication errors. You should not be concerned unless the errors do not clear after a few moments or if they disrupt ValveLink
software configuration, calibration, or diagnostic activities. If a disruption occurs, disable burst mode during these activities and
turn it back on when completed.

Once burst mode is enabled, the digital valve controller will continue to burst HART command 3 until the burst mode
is disabled. Even if instrument power is lost, the instrument will continue to burst command 3 when power is restored.
Troubleshooting
Refer to table 2 for Tri‐Loop diagnostic status messages.
To reach the Diagnostic Status menu using the Trex communicator or the Field Communicator, select
Diagnostics/Service, Test Device, and Status (fast key sequence 1‐1‐1).
Other Tri‐Loop parameters can be access using the Trex communicator, Field Communicator or AMS Device Manager.
Refer to figure 2 for the menu tree, and table 3 for the fast‐key sequence.
