 Change Burst Enable—Turns Burst Mode on and
off. Actual valves are Burst Enable = Disabled(Polled),
Enabled.
 Burst Command—There are four burst mode
commands. Command 3 is recommended for use with
the Rosemount 333 HART Tri-Loop HART-to-analog
signal converter. The other three are not used at this
time.
 Change Burst Command—Allows you to pick the
command to be sent from the instrument when Burst
Mode is on. Select HART Univ Cmd 1, HART Univ
Cmd 2, HART Univ Cmd 3, or DVC6000 Cmd 148.
 Cmd 3 Configured Pressure—Command 3
provides the following variables:
Primary variable—analog input in % or ma,
Secondary variable—travel target in % of ranged
travel,
Tertiary variable—supply or output pressure in psig,
bar, kPa, or kg/cm
2
. Select Cmd 3 Configured
Pressure from the Burst menu to select if the output A,
output B, differential (A−B), or supply pressure is sent.
Quaternary variable—travel in % of ranged travel.
Protection
 Protection
When the digital valve controller is in SIS mode, and
protection is on, the instrument cannot be taken Out of
Service. Protection must be turned off to change the
instrument mode.
To change an instrument’s protection, press the Hot
key on the Field Communicator and select Protection
or select Configure, Detailed Setup, Mode and
Protection, and Protection.
Two levels of protection are available:
 None—Neither setup nor calibration is protected.
Allows changing calibration and setup parameters.
 Config & Calib—Both setup and calibration are
protected. Prohibits changing calibration and protected
setup parameters.
Table 4-3 lists configurable parameters in the
instrument and the requirements for modifying these
parameters, in terms of instrument mode and
protection.

WARNING
Changes to the tuning set may cause
the valve/actuator assembly to stroke.
To avoid personal injury and property
damage caused by moving parts,
keep hands, tools, and other objects
away from the valve/actuator
assembly.
Travel Tuning Set— There are eleven tuning sets to
choose from. Each tuning set provides a preselected
value for the digital valve controller gain settings.
Tuning set C provides the slowest response and M
provides the fastest response. Table 4-2 lists the
proportional gain, velocity gain and minor loop
feedback gain values for preselected tuning sets.
In addition, you can select User Adjusted or Expert,
which allows you to modify tuning of the digital valve
controller. With User Adjusted, you specify the
proportional gain; an algorithm in the Field
Communicator calculates the velocity gain and minor
loop feedback gain. With Expert you can specify the
proportional gain, velocity gain, and minor loop
feedback gain.
