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.

 Rerange by manually setting range points with a Field Communicator, AMS Device Manager, or LOI.  Rerange with a pressure input source and a Field Communicator, AMS Device Manager, LOI, or local

zero and span buttons

Rerange with an applied pressure source using local zero and span buttons

If ordered, local zero and span buttons (option code D4) can be used to rerange the transmitter with an applied pressure. Refer to Figure 2-9 on page 13 for analog zero and span button location.

To rerange the transmitter using the span and zero buttons, perform the following 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 zero button for at

 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 transmitter detects a pressure of 25 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.

Configuration

January 2017

Reference Manual

00809-0100-4007, Rev BA

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.
