OVERVIEW This section contains information on commissioning and operating

Rosemount 3051N Smart Pressure Transmitters. Tasks that should be performed on the bench prior to installation are explained in this section.

When the HART Communicator is referenced, it refers to either the Rosemount 275 or Rosemount 375 as documented in Rosemount Report D2001019.

For your convenience, typical HART Communicator fast key sequences are listed for most software functions. These fast key sequences are the same for both the Rosemount 275 and Rosemount 375 Communicators. If you are unfamiliar with the communicator or how to follow fast key sequences, please refer to Appendix A for communicator operations.

A typical transmitter software configuration data worksheet is provided in Section 5.

SAFETY MESSAGES Procedures and instructions in this section may require special precautions to

ensure the safety of the personnel performing the operations. Information that raises potential safety issues is indicated by a warning symbol ( ). Refer to the following safety messages before performing an operation preceded by this symbol.

Warnings

Explosions can result in death or serious injury.

• Do not remove the transmitter covers in explosive environments when the circuit is alive.

Rosemount 3051N

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.

June 2008

FAILURE MODE ALARM Rosemount 3051N transmitters automatically and continuously perform

self-diagnostic routines. If the self-diagnostic routines detect a failure, the transmitter drives its output outside of the normal saturation values. The transmitter will drive its output low or high based on the position of the failure mode alarm jumper. See Table 2-1 for failure mode and saturation output levels. To select alarm position, see “Configuring Transmitter Alarm and Security Jumper Procedure” in Section 2.

Table 2-1. Standard 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

NOTE

You can alter the actual transmitter mA output values by performing an analog output trim.

NOTE

When a transmitter is in an alarm condition, the hand-held HART Communicator indicates the analog output the transmitter would drive if the alarm condition did not exist. The transmitter will alarm high in the event of failure if the alarm jumper is removed.

Alarm Level Verification Transmitters allow verification testing of alarm current levels. If you replace

the LCD meter, reconfigure or make any changes to the transmitter, verify the transmitter alarm level before you return the transmitter to service. This feature is also useful in testing the reaction of your control system to a transmitter in an alarm state. To verify the transmitter alarm values, perform a loop test and set the transmitter output to the alarm value (see Table 2-1 and “Loop Test” in Section 2).

TRANSMITTER

There are three security methods with the Rosemount 3051N transmitter:

SECURITY

Rosemount 3051N

1. Security Jumper: prevents all writes to transmitter configuration.

2. Local Keys (Local Zero and Span) Software Lock Out: prevents changes to transmitter range points via local zero and span adjustment keys. With local keys security enabled, changes to configuration are possible via HART.

3. Physical Removal of Local Keys (Local Zero and Span) Magnetic Buttons: removes ability to use local keys to make transmitter range point adjustments. With local keys security enabled, changes to configuration are possible via HART.

NOTE

If the security jumper is not installed, the transmitter will continue to operate in the security OFF configuration.

Security Jumper (Write Protect)

Local Zero and Span (Local Keys) Software Lock Out

Physical Removal of Local Zero and Span (Local Keys)

CONFIGURING TRANSMITTER ALARM AND SECURITY JUMPER PROCEDURE

You can prevent changes to the transmitter configuration data with the write protection jumper. Security is controlled by the security (write protect) jumper located on the electronics board or meter face. Position the jumper on the transmitter circuit board in the “ON” position to prevent accidental or deliberate change of configuration data.

If the transmitter write protection jumper is in the “ON” position, the transmitter will not accept any “writes” to its memory. Configuration changes, such as digital trim and reranging, cannot take place when the transmitter security is on.

To enable this feature, see “Local Span and Zero Control (Local Keys)” in Section 2.

To remove the magnetic buttons used to activate the local zero and span, use a small slotted head screwdriver and pry off the small, plastic cap located under the approval tag. Remove button assemblies and discard.

To reposition the jumpers, follow the procedure described below.

1. If the transmitter is installed, secure the loop and remove power.

2. Remove the housing cover opposite the field terminal side. Do not remove the transmitter covers in explosive atmospheres when the circuit is alive.

3. Reposition the jumpers as desired.

• Figure 2-1 shows the jumper positions for Electronics Boards.

• Figure 2-2 shows transmitters with an optional LCD meter.

4. Reattach the transmitter cover. Transmitter covers must be fully engaged to meet explosionproof requirements.

COMMISSIONING THE ROSEMOUNT 3051N WITH A HART-BASED COMMUNICATOR

Commissioning consists of testing the transmitter and verifying transmitter configuration data. You may commission Rosemount 3051N transmitters either before or after installation. Commissioning the transmitter on the bench before installation using a HART-based Communicator ensures that all transmitter components are in good working order and acquaints you with the operation of the device.

Current Meter

00809-0100-4808, Rev CA June 2008

Rosemount 3051N

To commission on the bench, connect the transmitter and the communicator as shown in Figure 2-3. Make sure the instruments in the loop are installed in accordance with intrinsically safe or nonincendive field wiring practices before connecting a communicator in an explosive atmosphere. Connect the communicator leads at any termination point in the signal loop. It is most convenient to connect them to the terminals labeled “COMM” on the terminal block. Connecting across the “TEST” terminals will prevent successful communication. To avoid exposing the transmitter electronics to the plant environment after installation, set all transmitter jumpers during the commissioning stage on the bench.

For 4–20 mA transmitters, you will need a power supply capable of providing

10.5 to 55 V dc at the transmitter, and a meter to measure output current. To enable communication, a resistance of at least 250 ohms, but within the transmitter load limitations (see Figure 3-7 “Power Supply Load Limitations.” in Section 3) must be present between the communicator loop connection and the power supply. Do not use inductive-based transient protectors with the Rosemount 3051N.

Setting the Loop to Manual

Wiring Diagrams (Bench Hook-up)

FIGURE 2-3. Bench Hook-up (4–20 mA Transmitters).

Whenever you are preparing to send or request data that would disrupt the loop or change the output of the transmitter, you must set your process application loop to manual. The HART Communicator will prompt you to set the loop to manual when necessary. Keep in mind that acknowledging this prompt does not set the loop to manual. The prompt is only a reminder; you have to set the loop to manual yourself as a separate operation.

Connect the bench equipment as shown in Figure 2-3 and turn on the HART-based Communicator by pressing the ON/OFF key. The communicator will search for a HART-compatible device and will indicate when the connection is made. If the communicator fails to connect, it will indicate that no device was found. If this occurs, refer to Section 4: Troubleshooting.

REVIEW CONFIGURATION DATA

HART Comm 1, 5

NOTE

Information and procedures in this section that make use of HART Communicator fast key sequences assume that the transmitter and communicator are connected, powered, and operating correctly. If you are not familiar with the HART Communicator or fast-key sequences, refer to Appendix A: HART Communicator.

Before you place the transmitter into operation, it is recommended that you review the transmitter configuration data that was set at the factory. You should review the following configuration data:

Transmitter Model Type

Tag Range

Date Descriptor

Message Minimum and Maximum

Sensor Limits

Minimum Span Units

4 and 20 mA points Output (linear or sq. root)

Damping Alarm Setting (high, low)

Security Setting (on, off) Local Zero/Span Keys

NOTE

Regardless of the range points, the Rosemount 3051N 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 in H 3051N, and the transmitter detects a pressure of 25 inH the 25 inH

O reading and a 250% of span reading. However, there may be up

O on a range code 1 Rosemount

O, it digitally outputs

to ±5.0% error associated with output outside of the range points.

Sensor Temperature The Rosemount 3051N contains a temperature sensor just above its pressure

HART Comm. 1, 1, 4

sensor in the sensor module. When reading this temperature, keep in mind that this is not a process temperature reading.

BASIC SETUP

Set Process Variable Units

HART Comm. 1, 3, 2

The PV Unit command sets the process variable units to allow you to monitor your process using the appropriate units of measure. Select from the following engineering units:

•inH2O•bar

• inHg • mbar

•ftH

O • g/cm

•mmH2O • kg/cm

•mmHg •Pa

•psi •kPa

• torr • atm

•inH

O at 4 °C • mmH2O at 4 °C

Set Output Activate the transmitter square root output option to make the analog output

HART Comm. 1, 3, 5

proportional to flow. As the input approaches zero, the Rosemount 3051N automatically switches to a linear output in order to ensure a more smooth, stable output near zero. See Figure 2-5.

The transition from linear to square root is not adjustable. It occurs at 0.8% of ranged pressure input or 8.9% of full-scale flow output.

From 0 percent to 0.6 percent of the ranged pressure input, the slope of the curve is unity (y = x). This allows accurate calibration near zero. Greater slopes would cause large changes in output for small changes at input. From

0.6 percent to 0.8 percent, the slope of the curve equals 42 (y = 42x) to achieve continuous transition from linear to square root at the transition point.

range values as often as necessary to reflect changing process conditions.

You may use one of three methods to rerange the transmitter. Each method is unique; examine all three closely before deciding which method to use.

Reranging using only the communicator changes the values of the analog 4 and 20 mA points independently without a pressure input.

NOTE

Changing the lower or upper range point results in similar changes to the span.

To rerange using only the communicator, enter the fast-key sequence above, select 1 Keypad input, and follow the on-line instructions. Or enter the values

directly from the ONLINE screen.

If the transmitter security jumper is in the ON position, you will not be able to

make adjustments to the zero and span. Refer to Figure 2-1 for the appropriate placement of the transmitter security jumper.

Rerange with a Pressure Input Source and a Communicator

HART Comm. 1, 2, 3, 1, 2

Rerange with a Pressure Input Source and the Local Zero and Span Buttons

Reranging using the communicator and a pressure source or process pressure is a way of reranging the transmitter with a pressure input. When specific 4 and 20 mA points are not known process input can be used. This method changes the values of the analog 4 and 20 mA points.

NOTE

When you set the 4 mA point the span is maintained; when you set the 20 mA point the span changes. If you set the lower range point 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.

To rerange using the communicator and a pressure source or process pressure, enter the fast-key sequence above, select 2 Apply values, and follow the on-line instructions.

NOTE

If the transmitter security jumper is in the ON position, you will not be able to

make adjustments to the zero and span. Refer to Figure 2-1 for the appropriate placement of the transmitter security jumper.

Reranging using the local zero and span adjustments (see Figure 2-6) and a pressure source or process pressure is a way of reranging the transmitter with a pressure input and when a communicator is not available. When specific 4 and 20 mA points are not known process input can be used.

Span and Zero Adjustment Buttons

00809-0100-4808, Rev CA June 2008

Rosemount 3051N

To rerange the transmitter using the span and zero buttons, perform the following procedure:

1. Loosen the screw holding the label on top of the transmitter housing, and rotate the label to expose the zero and span buttons (see Figure 2-6).

2. Using a pressure source with an accuracy three to ten times the desired calibrated accuracy, apply a pressure equivalent to the lower range value to the high side of the transmitter.

3. To set the 4 mA point, press and hold the zero button for at least two seconds, then verify that the output is 4 mA. If a meter is installed, it will display ZERO PASS.

4. Apply a pressure equivalent to the upper range value to the high side of the transmitter.

5. To set the 20 mA point, press and hold the span button for at least two seconds, then verify that the output is 20 mA. If a meter is installed, it will display SPAN PASS.

NOTE

If the transmitter security jumper is in the ON position, or if the local zero and

span adjustments are disabled through the software, you will not be able to make adjustments to the zero and span using the local buttons. Refer to Figure 2-1 for the proper placement of the transmitter security jumper. Or refer to “Local Span and Zero Control (Local Keys)” in Section 2 for instructions on how to enable the span and zero buttons.

FIGURE 2-6. Local Zero and Span Adjustments.

After you rerange the transmitter using the span and zero adjustments, it is possible to disable the adjustments to prevent further reranging. Refer to “Local Span and Zero Control (Local Keys)” below for more information.

Damping The process variable (PV) Damp command changes the response time of the

HART Comm. 1, 3, 6

transmitter to smooth variations in output readings caused by rapid changes in input. Determine the appropriate damping setting based on the necessary response time, signal stability, and other requirements of the of loop dynamics of your system. The default damping value is 0.4 seconds, to any of eleven pre-configured, nominal damping values between 0 and 25.6 seconds.

LCD Meter Options The Meter Options command allows you to customize the LCD meter for use

HART Comm. 1, 4, 3, 4

in your application. You can configure the meter to display the following information:

• Engineering Units

• Percent of Range

• User-Configurable LCD Scale

• Alternating between any two of the above

The user-configurable scale is a feature that enables you to configure the LCD meter to a custom scale using a HART Communicator. With this feature you can define the decimal point position, the upper range value, the lower range value, the engineering units, and the transfer function. Refer to “Custom Meter Configuration” in Section 6 for complete configuration information.

DIAGNOSTICS AND SERVICE

The Local keys command allows software control over the use of the local span and zero adjustments. To enable or disable the span and zero adjustment buttons on your transmitter, perform the fast key sequence at left.

NOTE

Disabling the local keys does not disable all transmitter configuration changes. With the local keys disabled, you can still make changes to the transmitter configuration—including range values—using a HART Communicator.

The Sensor Temperature Output Unit Selection command selects between Celsius and Fahrenheit units for output of the sensor temperature. The sensor temperature output is accessible via HART only.

The diagnostics and service functions listed here are primarily for use after you install the transmitter in the field. The transmitter test feature is designed to verify that the transmitter is operating properly, and can be performed either on the bench or in the field. The loop test feature is designed to verify proper loop wiring and transmitter output, and should only be performed after you install the transmitter.

routine than that performed continuously by the transmitter. The transmitter test routine can quickly identify potential electronics problems. If the transmitter test detects a problem, messages to indicate the source of the problem are displayed on the communicator screen.

Loop Test The Loop Test command verifies the output of the transmitter, the integrity of

HART Comm. 1, 2, 2

the loop, and the operations of any recorders or similar devices installed in the loop. To initiate a loop test, perform the following procedure:

1. Connect a reference meter to the transmitter. To do so, either connect the meter to the test terminals on the transmitter terminal block, or shunt the power to the transmitter through the meter at some point in the loop.

2. From the ONLINE screen, select 1 Device Setup, 2 Diagnostics and

Service, 2 Loop Test, to prepare to perform a loop test.

3. Select OK after you set the control loop to manual (see “Setting the

loop to Manual”). The communicator displays the loop test menu.

4. Select a discreet milliamp level for the transmitter to output. At the

CHOOSE ANALOG OUTPUT prompt, select 1 4mA, 2 20mA, or

select 3 other to manually input a value. IF test to verify the output of a transmitter, THEN 4 and 20 mA. IF transmitter alarm levels, THEN an alarm state (see Table 2-1).

5. Check the electrical current meter installed in the test loop to verify that it reads the value you commanded the transmitter to output. IF the readings match, THEN configured and functioning properly. IF

CALIBRATION Calibrating a smart transmitter is different from calibrating an analog

transmitter. The one-step calibration process of an analog transmitter is done in three steps with a smart transmitter:

• Rerange—sets the 4 and 20 mA points at the desired pressures;

• Sensor T rim—Adjusts the position of the factory characterization curve

to optimize the transmitter performance over a specified pressure range or to adjust for mounting effects

• Analog Output Trim—Adjusts the analog output to match the plant

standard or the control loop.

Reference Manual

Smart transmitters operate differently than analog transmitters. A smart transmitter uses a microprocessor and sensor memory that contains information about the sensor’s specific characteristics in response to pressure and temperature inputs. A smart transmitter compensates for these sensor variations. The process of generating the sensor performance profile is called factory characterization. Factory characterization also provides the ability to readjust the 4 and 20 mA points without applying pressure to the transmitter.

The trim and rerange functions also differ. Reranging sets the transmitter analog output to the selected upper and lower range points and can be done with or without an applied pressure. Reranging does not change the factory characterization curve stored in the microprocessor. Sensor trimming requires an accurate pressure input and adds additional compensation that adjusts the position of the factory characterization curve to optimize transmitter performance over a specific pressure range.

NOTE

Sensor trimming adjusts the position of the factory characterization curve. It is possible to degrade the performance of the transmitter if the sensor trim is done improperly or with inaccurate equipment. Contact Rosemount Nuclear Instruments, Inc. at 952-949-5210 if you have questions.

Rosemount 3051N

Calibration Overview Complete calibration of the Rosemount 3051N Pressure Transmitter involves

the following tasks:

Configure the Analog Output Parameters

• Set Process Variable Units (page 2-8)

• Set Output Type – Linear or Square Root (page 2-8)

• Set the Range Points (page 2-9)

• Set Damping (page 2-12)

Calibrate the Sensor

• Full Trim (page 2-18)

• Zero Trim (page 2-17)

Calibrate the 4–20 mA Output (Digital-to-Analog [D/A] Signal Conversion)

• 4–20 mA Output Trim (page 2-19) or

• 4–20 mA Output Trim Using Other Scale (page 2-19)

Figure 2-7 illustrates the Rosemount 3051N transmitter data flow. This data flow can be summarized in four major steps:

1. A change in pressure is measured by a change in the sensor output (Sensor Signal).

2. The sensor signal is converted to a digital format that can be understood by the microprocessor (Analog-to-Digital Signal Conversion).

3. Corrections are performed in the microprocessor to obtain a digital representation of the process input (Digital PV).

4. The Digital PV is converted to an analog value (Digital-to-Analog Signal Conversion).

Figure 2-7 also identifies the approximate transmitter location for each calibration task. Note that the data flows from left to right, and a parameter change affects all values to the right of the changed parameter.

Not all calibration procedures should be performed for each Rosemount 3051N transmitter. In addition, some procedures are appropriate for bench calibration but should not be performed during field calibration. Table 2-2 identifies the recommended calibration procedures for each type of Rosemount 3051N transmitter for both bench and field calibration.

Deciding Which Trim Procedure to Use

Sensor Trim You can trim the sensor using either the full trim or the zero trim function. The

2-16

To decide which trim procedure to use, you must first determine whether the analog-to-digital section or the digital-to-analog section of the transmitter electronics is in need of calibration. To do so, refer to Figure 2-7 and perform the following procedure:

trim functions vary in complexity, and their use is application-dependent. Both trim functions alter the transmitter’s interpretation of the input signal.

A zero trim is a single-point 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 full trim over the full sensor range.

1. Connect a pressure source, a HART Communicator, and a digital readout device to the transmitter.

2. Establish communication between the transmitter and the communicator.

3. Apply pressure equal to the upper range point pressure (100 inH

for example).

4. Compare the applied pressure to the Process Variable (PV) line on the Communicator On-line Menu. IF communicator does not match the applied pressure, and you are confident that your test equipment is accurate, THEN

5. Compare the Analog Output (AO) line on the communicator on-line menu to the digital readout device. IF

Rosemount 3051N

When performing a zero trim, ensure that the equalizing valve is open and all wet legs are filled to the correct levels.

NOTE

Do not perform a zero trim on Rosemount 3051N Absolute pressure transmitters. A zero trim is zero-based, and absolute pressure transmitters

reference absolute zero. To correct mounting position effects on a Rosemount 3051N Absolute Pressure Transmitter, perform a low trim within the full sensor trim function. The low trim function provides a “zero” correction similar to the zero trim function but it does not require the input to be zero-based.

A full trim is a two-point sensor calibration where two end-point pressures are applied, and all output is linearized between them. You should 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 factory-established characterization curve is not changed by this procedure. The trim values allow you to optimize performance over your specified measuring range at the calibration temperature.

Zero Trim To calibrate the sensor with a HART Communicator using the Zero Trim

HART Comm. 1, 2, 3, 3, 1

function, perform the following procedure.

1. Vent the transmitter and attach a communicator to the measurement loop.

2. From the communicator menu select 1 Device setup, 2 Diagnostics and service, 3 Calibration, 3Sensor trim, 1 Zero trim to prepare to adjust the zero trim.

NOTE

The transmitter must be within 3% of true zero (zero-based) in order to calibrate it using the zero trim function.

3. Follow the commands provided by the communicator to complete the adjustment of the zero trim.

Compensating Rosemount 3051N Range 4 and 5 Differential Transmitters for Line Pressure

Rosemount 3051N Range 4 and Range 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 (P

) in these applications.

Rosemount 3051N differential pressure transmitter ranges 0, 1, 2, and 3 do not require this procedure because the optimization occurs in the sensor. See “Static Pressure Effect” on page 5-3 for additional details.

Applying high static pressure to Rosemount 3051N Range 4 and Range 5 pressure transmitters causes a systematic shift in the output. This shift is linear with static pressure; correct it by performing the “Full Trim” on page 2-18, after determining the corrected input values as noted below.

The following specifications show the static pressure effect for Rosemount 3051N Range 4 and Range 5 transmitters used in differential pressure applications:

Zero Effect:

±0.1% of the upper range limit per 1000 psi (6,9 MPa) for line pressures (P

) from 0 to 2000 psi (0 to 13,8 MPa)

±[0.2 + 0.2 (P

-2000) / 1000]% of the upper range limit per 1000 psi

(6,9 MPa) for line pressures above 2000 psi (13,8 MPa) and ≤ 3626 psi (25 MPa)

Span Effect:

Correctable to ±0.2% of reading per 1000 psi for line pressures from 0 to 3626 psi.

2-20

The systematic span shift caused by the application of static line pressure is –1.00% of input reading per 1000 psi for 3051N Range 4 transmitters, and –1.25% of reading per 1000 psi for Range 5 transmitters.

Use the following example to compute corrected input values.

Example

A Rosemount 3051ND4 transmitter will be used in a differential pressure application where the static line pressure is 1200 psi. The transmitter is ranged so that the output is 4 mA at 500 inH

O and 20 mA at 1500 inH2O.

To correct for systematic error caused by high static line pressure, first use the following formulas to determine corrected values for the low trim and high trim.

= LRV + S (LRV) Ps

Where: LTc = Corrected Low Trim Value

LRV = Lower Range Value

S = –(Systematic Span shift per specification)

0 + (0.01/1000 psi)(1500 in H20)(1200 psi)

To complete a Rosemount 3051N full trim, enter the corrected values for low trim (LT) and high trim (HT). Refer to “Full Trim” on page 2-18.

Enter the corrected input values for low trim and high trim through the communicator keypad after you apply the nominal value of pressure as the transmitter input.

NOTE

After calibrating Rosemount 3051N Range 4 and Range 5 transmitters for high differential pressure applications, rerange the 4 and 20 mA points using the communicator to maintain the systematic static line pressure correction. You may re-zero the 4 mA point at line pressure after installation using the local zero button without affecting the completed calibration.

GENERAL CONSIDERATIONS

Special Draft Range 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

It is best to mount the transmitter with the isolating diaphragms parallel to the ground. Installing the transmitter in this way reduces oil head effect and provides for optimal temperature performance.

Be sure the transmitter is securely mounted. Tilting of the transmitter may cause a zero shift in the transmitter output.

Reducing Process Noise

It is often difficult to isolate the actual process variable from process noise in draft range applications. Pressure fluctuations and air currents can make accurate draft range measurements difficult to obtain.

There are two recommended methods of reducing process noise: output damping and, in gage applications, reference side filtering.

Output Damping

The output damping for the Rosemount 3051ND0 is factory set to 3.2 seconds as a default. If the transmitter output is still noisy, increase the damping time. If faster response is needed, decrease the damping time. Damping adjustment information is available in Section 2: Transmitter Functions.

MECHANICAL CONSIDERATIONS

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. Another method is to plumb the reference side to a chamber that has a small vent to atmosphere. If multiple draft transmitters are being used in an application, the reference side of each device can be plumbed to a chamber to achieve a common gage reference.

IMPORTANT

Install the enclosed pipe plug in unused conduit openings with a minimum of five threads engaged to comply with explosion proof requirements.

The following figures show dimensional drawings and installation examples of the Rosemount 3051N transmitters, including mounting brackets.

NOTE

For Rosemount 3051ND0 and 3051ND1, mount the transmitter solidly to prevent tilting. A tilt in the physical transmitter may cause a zero shift in the transmitter output.

Rosemount 3051N

Mounting The Rosemount 3051N Pressure Transmitter weighs approximately 6.0 lb

(2,7 kg) without additional options. For complete weight information, including options, see “Physical Specifications” in Section 5. Optional mounting brackets available with the Rosemount 3051N allow mounting to a panel or wall. The B4 Bracket Option for use with the Coplanar flange is 316 SST and provided with 316 SST bolts.

Bracket option B2 is a polyurethane painted carbon steel bracket designed for use in panel mounting the traditional flange (H2). The B2 bracket is provided with carbon steel bolts.

Bracket option BS is a 316LSST bracket provided with carbon steel bolts that is designed for use in panel mounting the traditional flange (option code H2). It is the same bracket used on other Rosemount Nuclear Instruments, Inc. nuclear qualified transmitters, including the Rosemount 1153 Series D and Rosemount 1154.

Bracket option PM is a SST pipe mount bracket assembly designed for use in pipe mounting the traditional Flange (option code H2). It is the same bracket used on other Rosemount Nuclear Instruments, Inc. nuclear qualified transmitters, including the Rosemount 1154 Series H.

When installing the transmitter to the mounting bracket, torque the mounting bolts to 21 ft.-lbs.

Dimensions and typical mounting configurations are contained in this section.

NOTE

The transmitter is calibrated in an upright position at the factory. If you mount the transmitter in any other position, the zero point will shift by an amount equivalent to the liquid head caused by the varied mounting position. To reset the zero point, refer to “Sensor Trim” in Section 2.

Mounting Requirements

Refer to Figure 3-6 for examples of the following mounting configurations:

Liquid Flow 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.

Gas Flow 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 Flow 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.

• Fill impulse lines with water to prevent the steam from contacting the transmitter directly and to ensure accurate measurement start-up.

00809-0100-4808, Rev CA June 2008

FIGURE 3-6. Typical Installation Examples to Illustrate Transmitter and Impulse Piping Locations.

Impulse Piping

The piping between the process and the transmitter must accurately transfer the pressure to obtain accurate measurements. There are several 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 depends on the process itself. 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 inch per foot (8 cm per m) upward from the transmitter toward the process connection.

• For gas service, slope the impulse piping at least 1 inch per foot (8 cm per 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.

• Keep the liquid head balanced on both legs of the impulse piping.

• Avoid conditions that might allow process fluid to freeze within the process flange.

2. Turn the housing up to 180 degrees to the left or right of its original (as

shipped) position. Do not rotate the housing more than 180 degrees.

Over-rotation will sever the electrical connection between the sensor module and the electronics module.

3. Retighten the housing rotation set screw.

The transmitter terminal block is in the compartment of the electronics housing labeled “FIELD TERMINALS.” The other compartment contains the transmitter electronics module. Connections for the HART-based communicator are attached beneath the terminal screws on the terminal block. Figure 3-7 shows power supply load limitations for the transmitter.

Power Supply 4–20 mA Transmitters

The dc power supply should provide power with less than 2 percent ripple. The total resistance load is the sum of the resistance of the signal leads and the load resistance of the controller, indicator, and related pieces. Note that the resistance of intrinsic safety barriers, if used, must be included.

NOTE

A minimum loop resistance of 250 ohms is required to communicate with a HART-based communicator. With 250 ohms of loop resistance, the transmitter will require a minimum of 16 volts to output 20 mA. If a single power supply is used to power more than one Rosemount 3051N transmitter, the power supply used, and circuitry common to the transmitters, should not have more than 20 ohms of impedance at 1200 Hz. For additional details, see Figure 3-7 "Power Supply Load Limitations."

Rosemount 3051N

Wiring To make connections, perform the following procedure:

1. Remove the housing cover on the side marked “FIELD TERMINALS.” Do not remove the cover in explosive atmospheres when the circuit is alive. All power to the transmitter is supplied over the signal wiring.

2. Connect the lead that originates at the positive side of the power supply to the terminal marked “+” and the lead that originates from the negative side of the power supply to the terminal marked “–”. Avoid contact with the leads and terminals. Do not connect the powered signal wiring to the test terminals. Power could damage the test diode in the test connection.

3. Plug and seal unused conduit connections on the transmitter housing to avoid moisture accumulation in the terminal side of the housing. If you do not seal the unused connections, mount the transmitter with the electrical housing positioned downward for drainage. Install wiring with a drip loop. Arrange the drip loop so the bottom is lower than the conduit connections and the transmitter housing.

NOTE

Signal wiring needs to be shielded, but use twisted pairs for best results. In order to ensure proper communication, use 24 AWG or larger wire, and do not exceed 5000 feet (1 500 meters).

Do not use inductive-based transient protectors, including the Rosemount 470, as they can adversely affect the output of Rosemount 3051N 4–20 mA transmitters.The Rosemount 3051N includes the transient protection terminal block (T1) as standard.

Signal Wiring Grounding

Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical equipment. You may ground the signal wiring at any one point on the signal loop, or leave it ungrounded. The negative terminal of the power supply is a recommended grounding point.

Grounding the Transmitter Case

ENVIRONMENTAL CONSIDERATIONS

The transmitter case should always be grounded in accordance with national and local electrical codes. The most effective transmitter case grounding method is 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 ( ), and is standard on all Rosemount 3051N transmitters.

• External Ground Assembly: This assembly is included as standard

with the transient protection terminal block (T1) included with the Rosemount 3051N

NOTE

Grounding the transmitter case using the threaded conduit connection may not provide a sufficient ground. The standard transient protection terminal block (T1) does not provide transient protection unless the transmitter case is properly grounded. Use the above guidelines to ground the transmitter case. Do not run the transient protection ground wire with signal wiring as the ground wire may carry excessive current if a lightning strike occurs.

The following guidelines can help optimize transmitter performance. Mount the transmitter to minimize ambient temperature changes, vibration, mechanical shock, and to avoid external contact with corrosive materials. “Specifications and Reference Data” in Section 5 lists transmitter temperature operating limits.

Access Requirements When choosing an installation location and position, take into account the

need for access to the transmitter.

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 technicians when the vents are used. In addition, consider the possible need for a testing or calibration input.

Housing Rotation

See “Housing Rotation” in Section 3.

Terminal Side of Electronics Housing

Mount the transmitter so that the terminal side is accessible. A 0.75-inch (19 mm) clearance is required for cover removal. Use a conduit plug on the unused side of the conduit opening.

Circuit Side of Electronics Housing

Provide 0.75 inches (19 mm) clearance for cover removal. Three inches of clearance is required for cover removal if a meter is installed.

Exterior of Electronics Housing

The integral span and zero adjustments are located under the label plate on the top of the transmitter. Allow a minimum of 1.0 inch of clearance above the transmitter if you intend to use the integral zero and span adjustments.

Cover Installation Always install the electronics housing covers metal-to-metal to ensure a

3-14

proper seal.

Installing the Meter For transmitters ordered with the LCD meter, the meter is shipped installed.

Installing the meter on an existing Rosemount 3051N transmitter requires a small instrument screwdriver and the meter kit (when the kit is made available by Rosemount Nuclear Instruments, Inc.).

To maintain the Rosemount 3051N qualification status, any piece parts for the Rosemount 3051N (if available) must be supplied by RNII.

The meter kit includes:

• one LCD meter assembly

• one extended cover with O-ring installed

• two nylon standoffs

• two captive screws

• one ten-pin interconnection header

Use the following procedure and Figure 6-1 to install the LCD meter.

the transmitter is installed in a loop, THEN secure the loop and

1. IF disconnect power.

2. Remove the transmitter cover opposite the field terminal side. Do not remove the instrument covers in explosive environments when the circuit is alive.

3. Remove the failure mode and alarm jumpers from the electronics module and insert them in their new positions above and below the meter readout on the meter assembly.

6-3

4. Insert the interconnection header in the ten-pin socket exposed by removal of the jumpers.

5. Remove the two captive screws from the electronics module. To do so, loosen the screws to release the module, then pull out the screws until they are stopped by the captive thread inside of the circuit board standoffs. Continue loosening the screws and remove them.

6. If necessary, rotate the electronics housing up to 180 degrees (left or right) to improve field access or to better view the LCD meter. To rotate the housing:

a. Loosen the housing rotation set screw using a

hex wrench.

b. Turn the housing up to 180 degrees to the left or right of its original

(as shipped) position. Do not rotate the housing more than 180

degrees. Over-rotation will sever the electrical connection between the sensor module and the electronics module.

c. Retighten the housing rotation set screw.

7. Decide which direction to orient the meter. Insert the long meter screws into the two holes on the meter assembly that coincide with the holes on the electronics module. You can install the meter in 90-degree increments for easy viewing. Position one of the four connectors on the back of the meter assembly to accept the interconnection header.

8. Attach the meter assembly to the electronics module by threading the screws into the captive threads and attaching the meter assembly to the interconnection pins. Tighten the screws to secure the meter assembly and electronics board in place.

9. Attach and tighten the extended cover. Transmitter covers must be fully engaged to meet explosion proof requirements and to achieve the proper environmental seal.

Rosemount 3051N

Option PM is a SST pipe mount bracket assembly designed for use in pipe mounting the Traditional Flange (H2). It is the same bracket used on other RNII nuclear qualified transmitters, including the Rosemount 1154 Series H.

When installing the transmitter to the optional mounting brackets, torque the bolts to 21 foot-pounds. See “Mounting” in Section 3 for additional mounting considerations.

June 2008

Traditional Flange (H2) The traditional flange option converts the mounting configuration of the

Rosemount 3051N to one similar to traditional style transmitters. This allows the Rosemount 3051N to replace traditional transmitters without changing existing manifolds, impulse piping, or bracket arrangements. The traditional flange also allows a higher process temperature at the process ports (300 °F [149 °C]) because of its ability to dissipate heat.

The traditional flange fits most existing mounting brackets. If a new bracket is required, use one of the bracket options described earlier. Figure 6-3 in Section 6 shows the traditional flange.

FIGURE 6-3. Typical Traditional Flange.

TRANSIENT PROTECTION TERMINAL BLOCK (T1)

INTRODUCTION This appendix provides basic communicator information on both the

Rosemount 275 and Rosemount 375 HART Communicators when used with a Rosemount 3051N Smart Pressure Transmitter. The Rosemount 275 and Rosemount 375 HART Communicators are not qualified, but may be used as Measurement and Test Equipment (MTE) as documented in Rosemount Report D2001019.

When the HART Communicator is referenced, it refers to either the Rosemount 275 or Rosemount 375.

This brief appendix will familiarize you with the HART Communicator but is not meant to replace the HART Communicator product manual. For additional information on the HART Communicator, refer to the HART Communicator Product Manual, publication number 00809-0100-4275 (Rosemount 275) or 00375-0047-0001 (Rosemount 375).

NOTE

You may need to upgrade the software in your HART Communicator in order to take advantage of all features of the Rosemount 3051N. If you initiate communication with a Rosemount 3051N using a Communicator that has a previous version of the transmitter Device Descriptors (DDs), the communicator will display the following message:

Notice: Upgrade software to access XMTR function. Continue with old description?

If you select YES, the communicator will communicate properly with the transmitter using the existing Rosemount 3051N DDs. However, software features added since the revision of the DDs in the communicator will not be accessible. If you select NO, the communicator will default to a generic transmitter functionality. Contact Rosemount Nuclear Instruments, Inc. at (952) 949-5210.

CONNECTIONS AND HARDWARE

FIGURE A-2. Rosemount 275 Rear Connection Panel with Optional NiCad Recharger Pack.

The HART Communicator can interface with a transmitter from the control room, the instrument site, or any wiring termination point in the loop through the communicator connections as shown in Figure A-2 and Figure A-3. To communicate, connect the HART Communicator in parallel with the instrument or load resistor. The connections are non-polarized. Before connecting the HART Communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or nonincendive field wiring practices.

NOTE

The HART Communicator needs a minimum of 250 ohms resistance in the loop to function properly. The HART Communicator is not a measurement device and does not need to be calibrated; it is a communications device through which you can read and adjust the transmitter configuration information. All variable outputs displayed by the communicator are functions of the transmitter.

Use this key to quickly access important, user-selectable options when connected to a HART-compatible device. Pressing the HOT KEY turns the HART Communicator on and displays the Hot Key Menu. See “Customizing the Hot Key Menu” in the Rosemount 275 HART Communicator manual for more information.

June 2008

Function Keys Use the four software-defined function keys, located below the LCD, to

perform software functions. On any given menu, the label appearing above a function key indicates the function of that key for the current menu. As you move among menus, different function key labels appear over the four keys. For example, in menus providing access to on-line help, the HELP label may appear above the F1 key. In menus providing access to the ONLINE MENU, the HOME label may appear above the F3 key. Simply press the key to activate the function. See your Rosemount 275 HART Communicator manual for details on specific function key definitions.

Alphanumeric and Shift Keys

FIGURE A-7. HART Communicator Alphanumeric and Shift Keys.

Data Entry Some menus require data entry. Use the alphanumeric and shift keys to enter

all alphanumeric information into the HART Communicator. If you press an alphanumeric key alone from within an edit menu, the bold character in the center of the key appears. These large characters include the numbers zero through nine, the decimal point (.), and the dash symbol (–).

To enter an alphabetic character, first press the shift key that corresponds to the position of the letter you want on the alphanumeric key. Then press the alphanumeric key. For example, to enter the letter “R”, first press the right shift key, then the “6” key (see Figure A-8). Do not press these keys simultaneously, but one after the other.

Fast Key Sequences HART fast key sequences provide quick on-line access to most transmitter

variables and functions. Instead of stepping your way through the menu structure using the action keys, you can press a HART fast key sequence to move from the ONLINE MENU to the desired variable or function. On-screen instructions guide you through the rest of the screens.

Fast Key Sequence Conventions

Fast Key Sequence Example

MENUS AND FUNCTIONS

The fast key sequences for the Rosemount 275 use the following conventions for their identification:

1 through 9–Refer to the keys located directly below the dedicated keypad.

Left Arrow–Refers to the LEFT ARROW directional key.

HART fast key sequences are made up of the series of numbers corresponding to the individual options in each step of the menu structure. For example, from the ONLINE MENU you can change the date. Following the menu structure, press 1 to reach Device Setup, press 3 for Basic Setup, press 4 for Device Info, press 1 for Date. The corresponding HART fast key sequence is 1, 3, 4, 1.

HART fast keys are operational only from the ONLINE MENU. If you use them consistently, you will need to return to the ONLINE MENU by pressing HOME (F3) when it is available. If you do not start at the ONLINE MENU, the HART fast key sequences will not function properly.

Use Table A-1, an alphabetical listing of most on-line functions, to find the corresponding HART fast key sequences. These codes are applicable only to Rosemount 3051N transmitters and the HART Communicator.

The HART Communicator is a menu driven system. Each screen provides a menu of options that can be selected as outlined above, or provides direction for input of data, warnings, messages, or other instructions.

Main Menu When the HART Communicator is turned on, one of two menus will appear. If

the HART Communicator is connected to an operating loop, the communicator will find the device and display the ONLINE MENU (see below). If it is not connected to a loop, the communicator will indicate that no device was found. When you press OK (F4), it will display the MAIN menu.

The MAIN menu provides the following options:

• Offline–The Offline option provides access to offline configuration data and simulation functions.

• Online–The Online option checks for a device and if it finds one, brings up the ONLINE MENU.

• Transfer–The Transfer option provides access to options for transferring data either from the HART Communicator (memory) to the transmitter (device) or vice versa. Transfer is used to move off-line data from the HART Communicator to the transmitter, or to retrieve data from a transmitter for off-line revision.

NOTE

Online communication with the transmitter automatically loads the current transmitter data to the HART Communicator. Changes in on-line data are made active by pressing SEND (F2). The transfer function is used only for off-line data retrieval and sending.

• Frequency Device–The Frequency Device option displays the frequency output and corresponding pressure output of current-to-pressure transmitters. This is not applicable to the

Rosemount 3051N.

• Utility–The Utility option provides access to the contrast control for the HART Communicator LCD screen and to the autopoll setting used in multidrop applications. Note that although the Rosemount 3051N has multi-drop capability, which is a HART protocol feature, the Rosemount 3051N is not qualified/dedicated for use in multi-drop mode.

Once selecting a MAIN menu option, the HART Communicator provides the information you need to complete the operation. If further details are required, consult the HART Communicator manual.

Online Menu The ONLINE MENU can be selected from the MAIN menu as outlined above,

or it may appear automatically if the HART Communicator is connected to an active loop and can detect an operating transmitter.

NOTE

The MAIN menu can be accessed from the ONLINE MENU. Press the left arrow action key to deactivate the on-line communication with the transmitter and to activate the MAIN menu options.

When configuration variables are reset in the on-line mode, the new settings are not activated until the data is sent to the transmitter. Press SEND (F2) when it is activated to update the process variables of the transmitter.

On-line mode is used for direct evaluation of a particular meter, re-configuration, changing parameters, maintenance, and other functions.

Analog Output Trim Digital Trim operation that allows adjustment of the output electronics to

conform to the plant standard. Three types of analog output trim are available: 4–20 mA Trim, 4–20 mA Other Scale, and Low Power. See “Analog Output Trim” in Section 2 . Low Power is not approved for use with the Rosemount 3051N.

Cloning Off-line operation that uses the HART Communicator (Rosemount 275 or

Rosemount 375) to copy configuration data from one transmitter to one or more other transmitters that require the same data.

Commissioning Functions performed with a HART-based communicator and the transmitter

which test the transmitter, test the loop, and verify transmitter configuration data. See “Commissioning the Rosemount 3051N with a HART-Based Communicator” in Section 2 .

Configuration Process of setting parameters that determine how the transmitter operates. Damping Output function that increases the response time of the transmitter to smooth

the output when there are rapid input variations. See “Damping” in Section 2 .

Descriptor Sixteen-character field for additional identification of the transmitter, its use, or

location. The descriptor is stored in the transmitter and can be changed using the HART-based communicator.

Digital Trim Format function that allows you to adjust the transmitter characterization for

purposes of digital calibration to plant standards. Digital Trim includes two separate operations: Sensor Trim and Analog Output Trim. See “Transmitter Functions” in Section 2.

Failure Mode Alarm Transmitter function that drives the analog output to a jumper-selectable high

or low value in the event of an electronics failure. See “Failure Mode Alarm” in Section 2 .

Factory Characterization Factory process during which each sensor module is subjected to pressures

and temperatures covering the full operating range. The sensor module memory stores data generated from this process for use by the microprocessor in correcting the transmitter output during operation.

Full Trim Sensor Trim function in which two accurate, end-point pressures are applied,

and all output is linearized between them. The selected end points should always be equal to or outside the LRV and URV. See “Full Trim” in Section 2 .

HART (Highway Addressable Remote Transducer) Protocol

Communications standard that provides simultaneous analog and digital signal transmission between control rooms and field devices such as transmitters. All Rosemount SMART FAMILY products communicate using the HART protocol.

Lower Range Limit (LRL) Lowest value of the measured variable that the transmitter can be configured

to measure.

Rosemount 3051N

June 2008

Lower Range V alue (LRV) Lowest value of the measured variable that the analog output of the

transmitter is currently configured to measure.

Multidropping 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.

Note that although the Rosemount 3051N has multi-drop capability, which is a HART protocol feature, the Rosemount 3051N is not qualified/dedicated for use in multi-drop mode.

Reranging Configuration function that changes the transmitter 4 and 20 mA settings. See

“Rerange” in Section 2 .

Send Data HART-based communicator command that transfers configuration data from

the hand-held communicator’s memory to the transmitter memory.

Sensor Trim Digital Trim function that allows you to adjust the digital process variable

reading to a precise pressure input. Zero Trim and Full Trim are the two Sensor Trim functions. See “Sensor Trim” in Section 2 .

Smart Term used to describe instruments that are microprocessor-based and feature

advanced communications capabilities. See Section 1: Introduction.

SMART FAMILY Rosemount pressure, temperature, level, and flow instruments with

microprocessor-based digital electronics.

Span Algebraic difference between the upper and lower range values. Tag Eight-character field for identifying the transmitter. The tag is stored in the

transmitter and can be changed using the HART Communicator (Rosemount 275 or Rosemount 375) and the Transmitter Information function.

Transmitter Address Unique number (1-15) used to identify a multidropped transmitter.

Transmitters that are not multidropped have 0 as an address. Note that although the Rosemount 3051N has multi-drop capability, which is a HART Protocol feature, the Rosemount 3051N is not qualified/dedicated for use in multi-drop mode.

Transmitter Security Jumper-selectable feature that prevents accidental or deliberate changes to

configuration data. See “Transmitter Security” in Section 2 .

Upper Range Limit (URL) Highest value of the measured variable that the transmitter can be configured

to measure.

Upper Range Value (URV)

Highest value of the measured variable that the analog output of the transmitter is currently configured to measure.

Zero Trim A zero-based, one-point adjustment used in differential pressure applications

to compensate for mounting position effects or zero shifts caused by static pressure. See “Zero Trim” in Section 2 .
