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.

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.

2.9.1 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.

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.

2.10 Configuring transmitter diagnostics

Diagnostics and service functions listed below are primarily for use after field installation.

2.10.1 Configuring power advisory diagnostic

The optional power advisory diagnostic (option code DA0) provides a means to detect issues that may jeopardize the integrity of the electrical loop. Some examples are: water entering the wiring compartment and making contact with the terminals, an unstable power supply nearing end of life, or heavy corrosion on the terminals.

This technology is based on the premise that once a transmitter is installed and powered up, the electrical loop has a baseline characteristic that reflects the proper installation. If the transmitter terminal voltage deviates from the baseline and outside the user configured threshold, the Rosemount 3051 can generate a HART alert or analog alarm.

To make use of this diagnostic, the user must first create a baseline characteristic for the electrical loop after the transmitter has been installed. The loop is automatically characterized with the push of a button. This creates a linear relationship for expected terminal voltage values along the operating region from 4–20 mA, see Figure 2-16.

Reference Manual

Figure 2-16. Baseline Operating Region

A. Terminal voltage B. 4 mA C. Output current D. 20 mA

Overview

Transmitters ordered with power advisory diagnostic (option code da0) are shipped with power advisory off as default and without any loop characterization performed. Once the transmitter is installed and powered up, loop characterization must be performed for Power Advisory diagnostic to function.

When the user initiates a loop characterization, the transmitter will check to see if the loop has sufficient power for proper operation. Then the transmitter will drive the analog output to both 4 and 20mA to establish a baseline and determine the maximum allowable terminal voltage deviation. Once this is complete, the user enters a sensitivity threshold called “Terminal Voltage Deviation Limit” and a check is in place to make sure this threshold value is valid.

Once the loop has been characterized and Terminal voltage deviation limit is set, power advisory actively monitors the electrical loop for deviations from the baseline. If the terminal voltage has changed relative to the expected baseline value, exceeding the configured Terminal Voltage Deviation Limit, the transmitter can generate an alert or alarm.

Note

Power advisory diagnostic in the Rosemount 3051 HART Pressure Transmitter monitors and detects changes in the terminal voltage from expected values to detect common failures. It is not possible to predict and detect all types of electrical failures on the 4–20 mA output. Therefore, Rosemount cannot absolutely warrant or guarantee that power advisory diagnostic will accurately detect failures under all circumstances.

Terminal voltage

This field shows the current terminal voltage value in Volts. The terminal voltage is a dynamic value and is directly related to the mA output value.

Terminal voltage deviation limit ±

The terminal voltage deviation limit should be set large enough that “expected” voltage changes do not cause false failures.

Configuration

Reference Manual

00809-0100-4007, Rev BA

Figure 2-17. Voltage Deviation Limit

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.

Configuration

January 2017

Resistance

This value is the calculated resistance of the electrical loop (in Ωs) measured during the characterize loop procedure. Changes in the resistance may occur due to changes in the physical condition of the loop installation. Baseline and previous baselines can be compared to see how much resistance has changed over time.

Power supply

This value is the calculated power supply voltage of the electrical loop (in volts) measured during the characterize loop procedure. Changes in this value may occur due to degraded performance of the power supply. Baseline and previous baselines can be compared to see how much the power supply has changed over time.

Characterize loop

Loop characterization must be initiated when the transmitter is first installed or when electrical loop characteristics have been intentionally altered. Examples include modified power supply level or loop resistance of the system, changing the terminal block on the transmitter, or adding the Smart Wireless

When the voltage deviation exceeds the set limit, four possible actions can be configured and can be set to “Latched” or “Unlatched”.

When the alert or alarm is “unlatched”, the alert or alarm will disappear if voltage deviation returns to a normal level. A “latched” alarm or alert will not disappear when the voltage deviation returns to normal levels. This requires the user to acknowledge and clear the alert or alarm.

2.11 Performing transmitter tests

2.11.1 Verifying alarm level

If the transmitter electronics board, sensor module, or LOI/ LCD display is repaired or replaced, verify the transmitter alarm level before returning the transmitter to service. This is useful in testing the reaction of the control system to a transmitter in an alarm state. Thus ensuring the control system recognizes the alarm when activated. To verify the transmitter alarm values, perform a loop test and set the transmitter output to the alarm value (see Figure 2-4, 2-6, and on page 15, and “Verifying alarm level” on page 24).

Note

Before returning transmitter to service, verify security switch is set to the correct position. Refer to

“Verify configuration” on page 7.

2.11.2 Performing an analog loop test

The analog loop test command verifies the output of the transmitter, the integrity of the loop, and the operations of any recorders or similar devices installed in the loop. It is recommended that the 4–20 mA points in addition to alarm levels are verified when installing, repairing, or replacing a transmitter.

The host system may provide a current measurement for the 4–20 mA HART output. If not, connect a reference meter to the transmitter by either connecting the meter to the test terminals on the terminal block, or shunting transmitter power through the meter at some point in the loop.

2.12 Configuring burst mode

Burst mode is compatible with the analog signal. Because the HART protocol features simultaneous digital and analog data transmission, the analog value can drive other equipment in the loop while the control system is receiving the digital information. Burst mode applies only to the transmission of dynamic data (pressure and temperature in engineering units, pressure in percent of range, Scaled Variable, and/or analog output), and does not affect the way other transmitter data is accessed. However, when activated, bust mode can slow down communication of non-dynamic data to the host by 50 percent.

Access to information other than dynamic transmitter data is obtained through the normal poll/response method of HART Communication. A Field Communicator, AMS Device Manager or the control system may request any of the information that is normally available while the transmitter is in burst mode. Between each message sent by the transmitter, a short pause allows the Field Communicator, AMS Device Manager or a control system to initiate a request.

2.13 Establishing multidrop communication

Multidropping transmitters refers to the connection of several transmitters to a single communications transmission line. Communication between the host and the transmitters takes place digitally with the analog output of the transmitters deactivated.

Multidrop installation requires consideration of the update rate necessary from each transmitter, the combination of transmitter models, and the length of the transmission line. Communication with transmitters can be accomplished with HART modems and a host implementing HART protocol. Each transmitter is identified by a unique address and responds to the commands defined in the HART protocol. Field Communicators and AMS Device Manager can test, configure, and format a multidropped transmitter the same way as a transmitter in a standard point-to-point installation.

Figure 2-19 shows a typical multidrop network. This figure is not intended as an installation diagram.

Note

A multidrop transmitter in HART Revision 7 mode has a fixed analog output of 4mA for all but one device. Only one device is allowed to have an active analog signal.

Configuration

January 2017

The Rosemount 3051 is set to address zero (0) at the factory, which allows operation in the standard point-to-point manner with a 4–20 mA output signal. To activate multidrop communication, the transmitter address must be changed to a number from 1 to 15 for HART Revision 5, or 1–63 for HART Revision 7. This change deactivates the 4–20 mA analog output, sending it to 4 mA. It also disables the failure mode alarm signal, which is controlled by the upscale/downscale switch position. Failure signals in multidropped transmitters are communicated through HART messages.

2.13.1 Changing a transmitter address

To activate multidrop communication, the transmitter poll address must be assigned a number from 1 to 15 for HART Revision 5, and 1–63 for HART Revision 7. Each transmitter in a multidropped loop must have a unique poll address.

Explosions could result in death or serious injury.

Installation of this transmitter in an explosive environment must be in accordance with the appropriate local, national, and international standards, codes, and practices. Review the approvals section of the Rosemount 3051 reference manual for any restrictions associated with a safe installation.

 Before connecting a Field Communicator in an explosive atmosphere, ensure the

instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.

 In an Explosion-Proof/Flameproof installation, do not remove the transmitter covers when

power is applied to the unit.

Process leaks may cause harm or result in death.

 Install and tighten process connectors before applying pressure.

Electrical shock can result in death or serious injury.

 Avoid contact with the leads and terminals. High voltage that may be present on leads can

cause electrical shock.

Electrical shock can result in death or serious injury.

 Avoid contact with the leads and terminals.

Process leaks could result in death or serious injury.

 Install and tighten all four flange bolts before applying pressure.  Do not attempt to loosen or remove flange bolts while the transmitter is in service.

Replacement equipment or spare parts not approved by Emerson for use as spare parts could reduce the pressure retaining capabilities of the transmitter and may render the instrument dangerous.

 Use only bolts supplied or sold by Emerson as spare parts.

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.

3.3 Considerations

3.3.1 Installation considerations

Measurement accuracy depends upon proper installation of the transmitter and impulse piping. Mount the transmitter close to the process and use a minimum of piping to achieve best accuracy. Keep in mind the need for easy access, personnel safety, practical field calibration, and a suitable transmitter environment. Install the transmitter to minimize vibration, shock, and temperature fluctuation.

Installation

Page 41

Reference Manual

00809-0100-4007, Rev BA

Important

Install the enclosed pipe plug (found in the box) in unused housing conduit opening with a minimum of five threads of engagement to comply with explosion-proof requirements.

For material compatibility considerations, see Material Selection Tech nica l Note.

3.3.2 Environmental considerations

Best practice is to mount the transmitter in an environment that has minimal ambient temperature change. The transmitter electronics temperature operating limits are –40 to 185 °F (–40 to 85 °C). Refer to Appendix A: Specifications and Reference Data that lists the sensing element operating limits. Mount the transmitter so that it is not susceptible to vibration and mechanical shock and does not have external contact with corrosive materials.

3.3.3 Mechanical considerations

Steam service

For steam service or for applications with process temperatures greater than the limits of the transmitter, do not blow down impulse piping through the transmitter. Flush lines with the blocking valves closed and refill lines with water before resuming measurement. Refer to Figure 3-9 on page 39 for correct mounting orientation.

Installation

January 2017

Side mounted

When the transmitter is mounted on its side, position the coplanar flange to ensure proper venting or draining. Mount the flange as shown in Figure 3-9 on page 39, keeping drain/vent connections on the bottom for gas service and on the top for liquid service.

3.3.4 Draft range considerations

Installation

For the Rosemount 3051CD0 draft range pressure transmitter, it is best to mount the transmitter with the isolators parallel to the ground. See Figure 3-1 on page 32 for a draft range installation example on a Rosemount 304 manifold. Installing the transmitter in this way reduces oil head effect.

Tilting of the transmitter may cause a zero shift in the transmitter output, but can be eliminated by performing a trim procedure.

Figure 3-1. Draft range Installation Example

A. Isolators

Reducing process noise

Rosemount 3051CD0 draft transmitters are sensitive to small pressure changes. Increasing the damping will decrease output noise, but will further reduce response time. In gage applications, it is important to minimize pressure fluctuations to the low side isolator.

Output damping

The output damping for the Rosemount 3051CD0 is factory set to 3.2. If the transmitter output is still noisy, increase the damping time. If faster response is needed, decrease the damping time. See

“Damping” on page 19 for damping adjustment information.

Reference side filtering

In gage applications it is important to minimize fluctuations in atmospheric pressure to which the low side isolator is exposed.

One method of reducing fluctuations in atmospheric pressure is to attach a length of tubing to the reference side of the transmitter to act as a pressure buffer.

3.4 Installation procedures

3.4.1 Mount the transmitter

For dimensional drawing information refer to Appendix A: Specifications and Reference Data on

page 115.

Process flange orientation

Mount the process flanges with sufficient clearance for process connections. For safety reasons, place the drain/vent valves so the process fluid is directed away from possible human contact when the vents are used. In addition, consider the need for a testing or calibration input.

Note

Most transmitters are calibrated in the horizontal position. Mounting the transmitter in any other position will shift the zero point to the equivalent amount of liquid head pressure caused by the varied mounting position. To reset zero point, refer to “Sensor Trim” on page 10.

Consider housing rotation

The electronics housing can be rotated up to 180 degrees in either direction to improve field access, or to better view the optional LCD/LOI Display. To rotate the housing, perform the following procedure:

1. Loosen the housing rotation set screw using a

2. Turn the housing left or right up to 180° from its original position. Over rotating will damage the

transmitter.

3. Re-tighten the housing rotation set screw.

Installation

January 2017

A. Housing rotation set screw (5/64-in.)

Electronics housing clearance

Mount the transmitter so the terminal side is accessible. Clearance of 0.75-in. (19 mm) is required for cover removal. Use a conduit plug in the unused conduit opening. Three inches of clearance is required for cover removal if a meter is installed.

Environmental seal for housing

For NEMA® 4X, IP66, and IP68 requirements, use thread seal (PTFE) tape or paste on male threads of conduit to provide a watertight seal.

Always ensure a proper seal by installing the electronics housing cover(s) so that metal contacts metal. Use Rosemount O-rings.

Flange bolts

The Rosemount 3051 can be shipped with a coplanar flange or a traditional flange installed with four

1.75-inch flange bolts. Mounting bolts and bolting configurations for the coplanar and traditional

flanges can be found on page 34. Stainless steel bolts supplied by Emerson are coated with a lubricant to ease installation. Carbon steel bolts do not require lubrication. No additional lubricant should be applied when installing either type of bolt. Bolts supplied by Emerson are identified by their head markings.

Bolt installation

Only use bolts supplied with the Rosemount 3051 or sold by Emerson as parts for the Rosemount 3051 transmitter. The use of non approved bolts could reduce pressure. Use the following bolt installation procedure:

3.4.2 Impulse piping

Mounting requirements

Impulse piping configurations depend on specific measurement conditions. Refer to Figure 3-9 on

page 39 for examples of the following mounting configurations:

Liquid measurement

 Place taps to the side of the line to prevent sediment deposits on the transmitter’s process isolators.  Mount the transmitter beside or below the taps so gases can vent into the process line.  Mount drain/vent valve upward to allow gases to vent.

Installation

Page 49

Reference Manual

00809-0100-4007, Rev BA

Gas measurement

 Place taps in the top or side of the line.  Mount the transmitter beside or above the taps so liquid will drain into the process line.

Steam measurement

 Place taps to the side of the line.  Mount the transmitter below the taps to ensure that the impulse piping will stay filled with

condensate.

 In steam service above 250 °F (121 °C), fill impulse lines with water to prevent steam from contacting

the transmitter directly and to ensure accurate measurement start-up.

Note

For steam or other elevated temperature services, it is important that temperatures at the process connection do not exceed the transmitter’s process temperature limits.

Best practices

The piping between the process and the transmitter must accurately transfer the pressure to obtain accurate measurements. There are five possible sources of error: pressure transfer, leaks, friction loss (particularly if purging is used), trapped gas in a liquid line, liquid in a gas line, and density variations between the legs.

The best location for the transmitter in relation to the process pipe is dependent on the process. Use the following guidelines to determine transmitter location and placement of impulse piping:

 Keep impulse piping as short as possible.  For liquid service, slope the impulse piping at least 1 in./ft (8 cm/m) upward from the transmitter

toward the process connection.

 For gas service, slope the impulse piping at least 1 in./ft (8 cm/m) downward from the transmitter

toward the process connection.

 Avoid high points in liquid lines and low points in gas lines.  Make sure both impulse legs are the same temperature.

 Use impulse piping large enough to avoid friction effects and blockage.  Vent all gas from liquid piping legs.  When using a sealing fluid, fill both piping legs to the same level.  When purging, make the purge connection close to the process taps and purge through equal lengths

of the same size pipe. Avoid purging through the transmitter.

 Keep corrosive or hot (above 250 °F [121 °C]) process material out of direct contact with the sensor

module and flanges.

 Prevent sediment deposits in the impulse piping.  Maintain equal leg of head pressure on both legs of the impulse piping.  Avoid conditions that might allow process fluid to freeze within the process flange.

3.4.3 Process connections

Coplanar or traditional process connection

Install and tighten all four flange bolts before applying pressure, or process leakage will result. When properly installed, the flange bolts will protrude through the top of the sensor module housing. Do not attempt to loosen or remove the flange bolts while the transmitter is in service.

Flange adapters

Rosemount 3051DP and GP process connections on the transmitter flanges are 1/4–18 NPT. Flange adapters are available with standard disconnect from the process by removing the flange adapter bolts. Use plant-approved lubricant or sealant when making the process connections. Refer to “Dimensional drawings” on page 97 for the distance between pressure connections. This distance may be varied ± both of the flange adapters.

To install adapters to a coplanar flange, perform the following procedure:

1. Remove the flange bolts.

2. Leaving the flange in place, move the adapters into position with the o-ring installed.

3. Clamp the adapters and the coplanar flange to the transmitter sensor module using the larger of the bolts supplied.

4. Tighten the bolts. Refer to “Flange bolts” on page 33 for torque specifications.

Whenever you remove flanges or adapters, visually inspect the PTFE O-rings. Replace with o-ring designed for Rosemount transmitter if there are any signs of damage, such as nicks or cuts. Undamaged O-rings may be reused. If you replace the O-rings, retorque the flange bolts after installation to compensate for cold flow. Refer to the process sensor body reassembly procedure in Section 6: Trouble-

shooting.

Note

PTFE O-rings should be replaced if the flange adapter is removed.

3.4.4 Inline process connection

Installation

January 2017

Inline gage transmitter orientation

Interfering or blocking the atmospheric reference port will cause the transmitter to output erroneous pressure values.

The low side pressure port on the inline gage transmitter is located in the neck of the transmitter, behind the housing. The vent path is 360 degrees around the transmitter between the housing and sensor (See

Figure 3-10).

Keep the vent path free of any obstruction, such as paint, dust, and lubrication by mounting the transmitter so that the process can drain away.

Installing high pressure coned and threaded connection

The transmitter comes with an autoclave connection designed for high pressure applications. Follow the steps below to properly connect the transmitter to your process:

1. Apply a process-compatible lubricant to the gland nut threads.

2. Slip the gland nut onto the tube, then thread the collar onto the tube end (the collar is reverse threaded).

3. Apply a small amount of process-compatible lubricant applied to the tube cone to help prevent galling and facilitate sealing. Insert the tubing into the connection and tighten finger tight.

4. Tighten the gland nut to a torque of 25 ft-lb.

Note

A weep hole has been designed into the transmitter for safety and leak detection. If fluid begins to leak from the weep hole, isolate the process pressure, disconnect the transmitter, and reseal until the leak is resolved.

3.5.1 Rosemount 305 Integral Manifold installation procedure

To install a Rosemount 305 Integral Manifold to a Rosemount 3051 Transmitter:

1. Inspect the PTFE sensor module O-rings. Undamaged O-rings may be reused. If the O-rings are damaged (if they have nicks or cuts, for example), replace with O-rings designed for Rosemount transmitter.

Important

If replacing the O-rings, take care not to scratch or deface the o-ring grooves or the surface of the isolating diaphragm while you remove the damaged O-rings.

2. Install the Integral Manifold on the sensor module. Use the four 2.25-in. manifold bolts for alignment. Finger tighten the bolts, then tighten the bolts incrementally in a cross pattern as seen in Figure 3-12 to final torque value. See “Flange bolts” on page 33 for complete bolt installation information and torque values. When fully tightened, the bolts should extend through the top of the sensor module housing.

4.6.2 Power supply for 4–20 mA HART

Transmitter operates on 10.5–42.4 Vdc at the terminal of the transmitter. The dc power supply should provide power with less than two percent ripple. A minimum of 16.6 V is required for loops with a 250 Ω resistance.

Note

A minimum loop resistance of 250 Ω is required to communicate with a Field Communicator. If a single power supply is used to power more than one Rosemount 3051 Transmitter, the power supply used, and circuitry common to the transmitters, should not have more that 20 Ω of impedance at 1200 Hz.

Perform the following procedure to make wiring connections:

1. Remove the housing cover on terminal compartment side. Do not remove the cover in explosive atmospheres when the circuit is live. Signal wiring supplies all power to the transmitter.

2. For 4–20 mA HART output, connect the positive lead to the terminal marked (pwr/comm+) and the negative lead to the terminal marked (pwr/comm –). Do not connect the powered signal wiring to the test terminals. Power could damage the test diode.

3. Plug and seal unused conduit connection on the transmitter housing to avoid moisture accumulation in the terminal side.

4.6.4 Signal wiring grounding

Signal cable shield grounding is summarized in Figure 4-7 on page 58. The signal cable shield and unused shield drain wire must be trimmed and insulated, ensuring that the signal cable shield and drain wire do not come in contact with the transmitter case. See “Transmitter case grounding” on page 59 for instructions on grounding the transmitter case. Follow the steps below to correctly ground the signal cable shield.

1. Remove the field terminals housing cover.

2. Connect the signal wire pair at the field terminals as indicated in Figure 4-6. The cable shield should:

 be trimmed close and insulated from touching the transmitter housing  continuously connect to the termination point  be connected to a good earth ground at the power supply end

Reference Manual

00809-0100-4007, Rev BA

3. At the field terminals, the cable shield and shield drain wire should be trimmed close and insulated from transmitter housing.

4. Reattach the Field Terminals Housing Cover; cover must be fully engaged to comply with explosion proof requirements.

5. At terminations outside the transmitter housing, the cable shield drain wire should be continuously connected.

a. Prior to the termination point, any exposed shield drain wire should be insulated as shown in

Figure 4-7 (B).

Transmitter case grounding

Always ground the transmitter case in accordance with national and local electrical codes. The most effective transmitter case grounding method is a direct connection to earth ground with minimal impedance. Methods for grounding the transmitter case include:

 Internal ground connection: The internal ground connection screw is inside the FIELD TERMINALS

side of the electronics housing. This screw is identified by a ground symbol ( ). The ground connection screw is standard on all Rosemount 3051 Transmitters. Refer to Figure 4-8 on page 59.

 External ground connection: The external ground connection is located on the exterior of the

transmitter housing. Refer to Figure 4-9 on page 59. This connection is only available with option V5 and T1.

Transient protection terminal block grounding

The transmitter can withstand electrical transients of the energy level usually encountered in static discharges or induced switching transients. However, high-energy transients, such as those induced in wiring from nearby lightning strikes, can damage the transmitter.

The transient protection terminal block can be ordered as an installed option (option code T1) or as a spare part to retrofit existing transmitters in the field. See “Spare parts” on page 150 for part numbers. The lightning bolt symbol shown in Figure 4-10 on page 60 identifies the transient protection terminal block.

5.4 Calibration overview

The Rosemount 3051 Pressure Transmitter is an accurate instrument that is fully calibrated in the factory. Field calibration is provided to the user to meet plant requirements or industry standards.

Complete calibration of the transmitter can be split into two halves, sensor calibration and analog output calibration.

Sensor calibration allows the user to adjust the pressure (digital value) reported by the transmitter to be equal to a pressure standard. The sensor calibration can adjust the pressure offset to correct for mounting conditions or line pressure effects. This correction is recommended. The calibration of the pressure range (pressure span or gain correction) requires accurate pressure standards (sources) to provide a full calibration.

Like the sensor calibration, the analog output can be calibrated to match the user's measurement system. The analog output trim (4–20 mA output trim) will calibrate the loop at the 4 and 20 mA points.

The sensor calibration and the analog output calibration combine to match the transmitter’s measurement system to the plant standard.

Calibrate the 4–20 mA output

 4–20 mA output trim (page 70)  4–20 mA output trim using other scale (page 70)

5.4.1 Determining necessary sensor trims

Bench calibrations allow for calibrating the instrument for its desired range of operation. Straight forward connections to pressure source allow for a full calibration at the planned operating points. Exercising the Transmitter over the desired pressure range allows for verification of the analog output.

“Trim the pressure signal” on page 66 discusses how the trim operations change the calibration. It is

possible to degrade the performance of the transmitter if a trim is done improperly or with inaccurate equipment. The transmitter can be set back to factory settings using the recall factory trim command in

“Recall factory trim—sensor trim” on page 68.

For transmitters that are field installed, the manifolds discussed in “Rosemount 305, 306, and 304

Manifolds” on page 43 allow the differential transmitter to be zeroed using the zero trim function. Both

3- and 5-valve manifolds are discussed. This field calibration will eliminate any pressure offsets caused by mounting effects (head effect of the oil fill) and static pressure effects of the process.

Determine the necessary trims with the following steps.

1. Apply pressure.

2. Check digital pressure, if the digital pressure does not match the applied pressure, perform a digital

Trimming with configuration buttons

Local configuration buttons are external buttons located underneath the top tag of the transmitter. There are two possible sets of local configuration buttons that can be ordered and used to perform trim operations: Digital Zero Trim and Local Operator Interface. To access the buttons, loosen screw and rotate top tag until buttons are visible.

 Local operator interface (M4): Can perform both digital sensor trim and the 4–20 mA output trim

(analog output trim). Follow same procedures listed in trimming with Field Communicator or AMS listed below.

 Digital zero trim (DZ): Used for performing a sensor zero trim. See “Determining calibration

frequency” on page 64 for trim instructions.

All configuration changes should be monitored by a display or by measuring the loop output. Figure 5-1 shows the physical differences between the two sets of buttons.

5.4.2 Determining calibration frequency

Calibration frequency can vary greatly depending on the application, performance requirements, and process conditions. Use the following procedure to determine calibration frequency that meets the needs of your application.

1. Determine the performance required for your application.

2. Determine the operating conditions.

3. Calculate the Total Probable Error (TPE).

4. Calculate the stability per month.

5. Calculate the calibration frequency.

Step 5: Calculate calibration frequency.

5.4.3 Compensating for span line pressure effects (range 4 and 5)

Rosemount 3051 Range 4 and 5 Pressure Transmitters require a special calibration procedure when used in differential pressure applications. The purpose of this procedure is to optimize transmitter performance by reducing the effect of static line pressure in these applications. The Rosemount 3051 Differential Pressure Transmitters (ranges 0 through 3) do not require this procedure because optimization occurs at the sensor.

The systematic span shift caused by the application of static line pressure is -0.95% of reading per 1000 psi (69 bar) for Range 4 transmitters, and –1 percent of reading per 1000 psi (69 bar) for Range 5 transmitters. Using the following procedure, the span effect can be corrected to ±0.2 percent of reading per 1000 psi (69 bar) for line pressures from 0 to 3626 psi (0 to 250 bar).

Use the following example to compute correct input values.

Example

A range 4 differential pressure HART transmitter (Rosemount 3051CD4...) will be used in an application with a static line pressure of 1200 psi (83 bar). The transmitter output is ranged with 4mA at 500 inH

(1,2 bar) and 20 mA at 1500 inH

O (3,7 bar). To correct for systematic error caused by high static line

pressure, first use the following formulas to determine the corrected values for the high trim value.

High trim value:

HT = (URV – [S/100 ⫻ P/1000 ⫻ LRV])

HT = Corrected high trim value

Where:

URV = Upper range value

S = Span shift per specification (as a percent of reading)

P = Static line pressure in psi

Operation and Maintenance

In this example:

Complete the upper sensor trim procedure as described in “Perform a sensor trim” on page 67. In the example above, when calculating the stability per month, apply the nominal pressure value of 1500 inH

O LO. However, enter the calculated correct upper sensor trim value of 1517.1 inH2O with a Field

Communicator.

Note

The Range Values for the 4 and 20 mA points should be at the nominal URV and LRV. In the example above, the values are 1500 and 500 inH Field Communicator. Modify, if needed, by following the steps in “Rerange the transmitter” on page 11.

5.5 Trim the pressure signal

5.5.1 Sensor trim overview

A sensor trim corrects the pressure offset and pressure range to match a pressure standard. The upper sensor trim corrects the pressure range and the lower sensor trim (zero trim) corrects the pressure offset. An accurate pressure standard is required for full calibration. A zero trim can be performed if the process is vented, or the high and low side pressure are equal (for differential pressure transmitters).

Zero trim is a single-point offset adjustment. It is useful for compensating for mounting position effects and is most effective when performed with the transmitter installed in its final mounting position. Since this correction maintains the slope of the characterization curve, it should not be used in place of a Sensor Trim over the full sensor range.

When performing a zero trim, ensure that the equalizing valve is open and all wet legs are filled to the correct levels. Line pressure should be applied to the transmitter during a zero trim to eliminate line pressure errors. Refer to “Manifold operation” on page 45.

Note

Do not perform a zero trim on Rosemount 3051T Absolute Pressure Transmitters. Zero trim is zero based, and absolute pressure transmitters reference absolute zero. To correct mounting position effects on a Rosemount 3051T Absolute Pressure Transmitter, perform a low trim within the sensor trim function. The low trim function provides an offset correction similar to the zero trim function, but it does not require zero-based input.

Upper and lower sensor trim is a two-point sensor calibration where two end-point pressures are applied, all output is linearized between them, and requires an accurate pressure source. Always adjust the low trim value first to establish the correct offset. Adjustment of the high trim value provides a slope correction to the characterization curve based on the low trim value. The trim values help optimize performance over a specific measurement range.

Performing a digital zero trim (option DZ)

A digital zero trim (option DZ) provides the same function as a zero/lower sensor trim, but can be completed in hazardous areas at any given time by simply pushing the zero trim button when the transmitter is at zero pressure. If the transmitter is not close enough to zero when the button is pushed, the command may fail due to excess correction. If ordered, a digital zero trim can be performed by utilizing external configuration buttons located underneath the top tag of the transmitter, see Figure 5-1

on page 64 for DZ button location.

1. Loosen the top tag of the transmitter to expose buttons.

2. Press and hold the digital zero button for at least two seconds then release to perform a digital zero trim.

c. Manifold:

Troubleshooting

January 2017

– Hold the process flange in place by installing the two alignment screws to finger tightness

(screws are not pressure retaining). Do not overtighten as this will affect module-to-flange alignment.

– Install the four 1.75-in. flange bolts by finger tightening them to the flange.

– Hold the process flange in place by installing the two alignment screws to finger tightness

(screws are not pressure retaining). Do not overtighten as this will affect module-to-flange alignment.

– Hold the flange adapters and adapter O-rings in place while installing (in the desired of the

four possible process connection spacing configurations) using four 2.88-in. bolts to mount securely to the coplanar flange. For gage pressure configurations, use two 2.88-in. bolts and two 1.75-in. bolts

– Contact the manifold manufacturer for the appropriate bolts and procedures.

3. Tighten the bolts to the initial torque value using a crossed pattern. See Table 6-5 on page 81 for appropriate torque values.

4. Using same cross pattern, tighten bolts to final torque values seen in Table 6-5 on page 81.

ASTM-A-193 Class 2, Grade B8M—Option L8 150 in-lb (17 N-m) 300 in-lb (34 N-m)

Note

If you replaced the PTFE sensor module O-rings, re-torque the flange bolts after installation to compensate for cold flow.

Note

For Range 1 transmitters: after replacing O-rings and re-installing the process flange, expose the transmitter to a temperature of 185 °F (85 °C) for two hours. Then re-tighten the flange bolts in a cross pattern, and again expose the transmitter to a temperature of 185 °F (85 °C) for two hours before calibration.

6.5.4 Installing drain/vent valve

1. Apply sealing tape to the threads on the seat. Starting at the base of the valve with the threaded end pointing toward the installer, apply five clockwise turns of sealing tape.

2. Tighten the drain/vent valve to 250 in-lb. (28.25 N-m).

3. Take care to place the opening on the valve so that process fluid will drain toward the ground and away from human contact when the valve is opened.
