Configuration Reference Manual
July 2020 00809-0100-4007
To rerange the transmitter using the Zero and Span buttons:
Procedure
1. Loosen the screw holding the top tag of the transmitter housing. Rotate the label to
expose the Zero and Span buttons.
2. Confirm device has local Zero and Span buttons by verifying blue retainer under the
tag.
3. Apply transmitter pressure.
4. Rerange the transmitter.
a) To change the zero (4 mA point) while maintaining the span, press and hold
the Zero button for at least two seconds; then release.
b) To change the span (20 mA) point while maintaining the zero point, press
and hold the Span button for at least two seconds and then release.
Note
4 and 20 mA points must maintain the minimum span defined in the Specifications
section of the Rosemount 3051 Product Data Sheet.
2.7.4
• If the transmitter security is on, you cannot adjust the zero and span. Refer to
Configuring transmitter security for security information.
• The span is maintained when you set the 4 mA point. The span changes when
you set the 20 mA point. If you set the lower range point to a value that causes
the upper range point to exceed the sensor limit, the transmitter automatically
sets the upper range point to the sensor limit and adjusts the span accordingly.
• Regardless of the range points, the Rosemount 3051 measures and reports all
readings within the digital limits of the sensor. For example, if you set the 4 and
20 mA points to 0 and 10 inH2O, and the transmitter detects a pressure of 25
inH2O, it digitally outputs the 25 inH2O reading and a 250 percent of range
reading.
Damping
The damping command changes the response time of the transmitter; higher values can
smooth variations in output readings caused by rapid input changes.
CAUTION
Improper assembly
Improper assembly of manifolds to traditional flange can damage sensor module.
For safe assembly of manifold to traditional flange, bolts must break back plane of
flange web (i.e., bolt hole) but must not contact sensor module housing.
Severe changes in the electrical loop may inhibit HART® communication or the ability
to reach alarm values. Therefore, Rosemount cannot absolutely warrant or guarantee
that the correct Failure alarm level (High or Low) can be read by the host system at the
time of annunciation.

2.9.1 Configuring alarm and saturation levels
24 Rosemount 3051
In normal operation, the transmitter drives the output in response to pressure from the
lower and upper saturation points. If the pressure goes outside of the sensor limits, or if
Reference Manual Configuration
00809-0100-4007 July 2020
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 selfdiagnostic 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
Set transmitter alarm.
Table 2-4: Rosemount Alarm and Saturation Values
Level 4-20 mA saturation 4-20 mA alarm
Low 3.9 mA ≤ 3.75 mA
High 20.8 mA ≥ 21.75 mA
Table 2-5: NAMUR-Compliant Alarm and Saturation Values
Level 4-20 mA saturation 4-20 mA alarm
Low 3.8 mA ≤ 3.6 mA
High 20.5 mA ≥ 22.5 mA
Table 2-6: Custom Alarm and Saturation Values
Level 4-20 mA saturation 4-20 mA alarm
Low 3.7 - 3.9 mA 3.6 - 3.8 mA
High 20.1 - 22.9 mA 20.2 - 23.0 mA
You can configure failure mode alarm and saturation levels using a Field Communicator,
AMS Device Manager, or 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 provides 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.

2.9.3
Configuring scaled variable
With the scaled variable configuration, you can create a relationship/conversion between
the pressure units and user-defined/custom units. There are two use cases for a scaled
variable. The first is to allow custom units to be displayed on the transmitter's LOI/LCD
display. The second is to allow custom units to drive the transmitter's 4-20 mA output.
If you desire custom units to drive the 4-20 mA output, you must remap scaled variable as
the primary variable. Refer to Re-mapping device variables.
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 cause by
process noise. Emerson highly recommends using the low flow cut off function in order
to have a stable output and avoid problems due to process noise at a low flow or no
flow condition. Enter a low flow cutoff value that is practical for the flow element in the
application.

Us a differential transmitter in a level application. Once installed on an empty tank with the
taps vented, the process variable reading is -209.4 inH2O. The process variable reading is
the head pressure created by fill fluid in the capillary. Based on Table 2-7, the scaled
variable configuration would be as follows:

DP Flow example
Use a differential pressure transmitter in conjunction with an orifice plate in a flow
application where the differential pressure at full scale flow is 125 inH2O.
Emerson highly recommends using 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. Enter a
low flow cutoff value that is practical for the flow element in the application. 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:
Table 2-8: Scaled Variable Configuration for Flow Application
Scaled variable units gal/h
Scaled data options square root
2.9.4
Pressure value position 2 125 inH2O
Scaled variable position 2 20,000 gal/h
Low flow cutoff 1000 gal/h
Note
Pressure value position 1 and scaled variable position 1 are always set to zero for a flow
application. You don't have to configure these values.
Re-mapping device variables
Use the re-mapping function to configure the transmitter primary, secondary, tertiary,
and quaternary variables (PV, 2V, 3V, and 4V). You can map the PV with a Field
Communicator, AMS Device Manager, or the LOI. You can only re-map variables (2V, 3V,
and 4V) via Field Communicator or AMS Device Manager.
Note
The variable assigned to the primary variable drives the 4-20 mA output. You can select
this value as Pressure or Scaled Variable. The 2, 3, and 4 variables only apply if you are
using HART® burst mode.
