2.4 Configuration basics
Set all transmitter hardware adjustments during commissioning to avoid exposing the transmitter
electronics to the plant environment after installation.
The Rosemount 3051 can be configured either before or after installation. Configuring the transmitter
on the bench using either a Field Communicator, AMS Device Manager, or LOI ensures all transmitter
components are in working order prior to installation. Verify the security switch is set in the unlock
position ( ) in order to proceed with configuration. See Figure 4-2 on page 53 for switch location.
2.4.1 Configuring on the bench
To configure on the bench, required equipment includes a power supply, and a Field Communicator,
AMS Device Manager, or LOI (option M4). Wire equipment as shown in Figure 2-1 below. To ensure
successful HART Communication, a resistance of at least 250 Ω must be present between the
transmitter and the power supply, see “Power supply for 4–20 mA HART” on page 56 for details.
Connect the Field Communicator leads to the terminals labeled “COMM” on the terminal block.

Configuring with a LOI
The LOI requires option code M4 to be ordered. To activate the LOI push either configuration button.
Configuration buttons are located on the LCD display (must remove housing cover to access), or
underneath the top tag of the transmitter. See Ta b le 2 - 2 for configuration button functionality and
Figure 2-3 for configuration button location. When using the LOI for configuration, several features
require multiple screens for a successful configuration. Data entered will be saved on a screen-by-screen
basis; the LOI will indicate this by flashing “SAVED” on the LCD display each time.
LOI menu trees are available in Appendix D: Local Operator Interface (LOI).

2.5 Setting the loop to manual
Whenever sending or requesting data that would disrupt the loop or change the output of the
transmitter, set the process application loop to manual control. The Field Communicator, AMS Device
Manager, or the LOI will prompt you to set the loop to manual when necessary. The prompt is only a
reminder; acknowledging this prompt does not set the loop to manual. It is necessary to set the loop to
manual control as a separate operation.
2.6 Verify configuration
It is recommended that various configuration parameters are verified prior to installation into the
process. The various parameters are detailed out for each configuration tool. Depending on what
configuration tool(s) are available follow the steps listed relevant to each tool.

2.7.2 Setting transmitter output (transfer function)
The Rosemount 3051 has two output settings: Linear and Square root. As shown in Figure 2-6 on
page 11, activating the square root options makes analog output proportional to flow, and includes a
fixed Low Flow Cutoff at 5 percent.
However, for Differential Pressure (DP) Flow and DP Level applications it is recommended to use scaled
variable. Refer to “Configuring scaled variable” on page 17 for setup instructions.

2.7.3 Rerange the transmitter
The range values command sets each of the lower and upper range analog values (4 and
20 mA points) to a pressure. The lower range point represents 0% of range and the upper range point
represents 100% of range. In practice, the transmitter range values may be changed as often as
necessary to reflect changing process requirements. For a complete listing of range and sensor limits,
refer to “Range and sensor limits” on page 91.
Select from one of the methods below to rerange the transmitter. Each method is unique; examine all
options closely before deciding which method works best for your process.

If the transmitter security is on, adjustments to the zero and span will not be able to be made. Refer
to “Configuring transmitter security” on page 53 for security information.
The span is maintained when the 4 mA point is set. The span changes when the
20 mA point is set. If the lower range point is set to a value that causes the upper range point to
exceed the sensor limit, the upper range point is automatically set to the sensor limit, and the span is
adjusted accordingly.
Regardless of the range points, the Rosemount 3051 will measure and report all readings within the
digital limits of the sensor. For example, if the 4 and 20 mA points are set to 0 and 10 inH

2.7.4 Damping
The damping command changes the response time of the transmitter; higher values can smooth
variations in output readings caused by rapid input changes. Determine the appropriate damping setting
based on the necessary response time, signal stability, and other requirements of the loop dynamics
within your system. The damping command utilizes floating point configuration allowing the user to
input any damping value within 0–60 seconds.

2.9 Detailed transmitter setup
2.9.1 Configuring alarm and saturation levels
Config uration
In normal operation, the transmitter will drive the output in response to pressure from the lower to
upper saturation points. If the pressure goes outside the sensor limits, or if the output would be beyond
the saturation points, the output will be limited to the associated saturation point.
The Rosemount 3051 Transmitter automatically and continuously performs self-diagnostic routines. If
the self-diagnostic routines detect a failure, the transmitter drives the output to configured alarm and
value based on the position of the alarm switch. See “Setting transmitter alarm” on page 55.

Failure mode alarm and saturation levels can be configured using a Field Communicator, AMS Device
Manager, and the LOI. The following limitations exist for custom levels:
Low alarm level must be less than the low saturation level
High alarm level must be higher than the high saturation level
Alarm and saturation levels must be separated by at least 0.1 mA
The configuration tool will provide an error message if the configuration rule is violated.
Note
Transmitters set to HART multidrop mode send all saturation and alarm information digitally; saturation
and alarm conditions will not affect the analog output. See also “Establishing multidrop
communication” on page 27.

The scaled variable configuration allows the user to create a relationship/conversion between the
pressure units and user-defined/custom units. There are two use cases for scaled variable. The first use
case is to allow custom units to be displayed on the transmitter's LOI/LCD display. The second use case is
to allow custom units to drive the transmitter's 4–20 mA output.

If the user desires custom units to drive the 4–20 mA output, scaled variable must be re-mapped as the
primary variable. Refer to “Re-mapping device variables” on page 20.
The scaled variable configuration defines the following items:
Scaled variable units - Custom units to be displayed.
Scaled data options - Defines the transfer function for the application
– Linear
– Square root
Pressure value position 1 - Lower known value point with consideration of linear offset.
Scaled variable value position 1 - Custom unit equivalent to the lower known value point.
Pressure value position 2 - Upper known value point
Scaled variable value position 2 - Custom unit equivalent to the upper known value point
Linear offset - The value required to zero out pressures effecting the desired pressure reading.
Low flow cutoff - Point at which output is driven to zero to prevent problems caused by process
noise. It is highly recommended to use the low flow cutoff function in order to have a stable output
and avoid problems due to process noise at a low flow or no flow condition. A low flow cutoff value
that is practical for the flow element in the application should be entered.

DP Flow example
A differential pressure transmitter is used in conjunction with an orifice plate in a flow application where
the differential pressure at full scale flow is 125 inH
scale flow is 20,000 gallons of water per hour. It is highly recommended to use the low flow cutoff
function in order to have a stable output and avoid problems due to process noise at a low flow or no flow
condition. A low flow cutoff value that is practical for the flow element in the application should be
entered. In this particular example, the low flow cutoff value is 1000 gallons of water per hour. Based on
this information, the Scaled Variable configuration would be as follows:

2.9.4 Re-mapping device variables
The re-mapping function allows the transmitter primary, secondary, tertiary, and quaternary variables
(PV, 2V, 3V, and 4V) to be configured as desired. The PV can be remapped with a Field Communicator,
AMS Device Manager, or a LOI. Variables (2V, 3V, and 4V) can only be re-mapped via Field Communicator
or AMS Device Manager.
Note
The variable assigned to the primary variable drives the 4–20 mA output. This value can be selected as
Pressure or Scaled Variable. The 2, 3, and 4 variables only apply if HART burst mode is being used.
