Explosions could result in death or serious injury.

 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.

2.3 Commissioning

Commissioning consists of testing the transmitter and verifying transmitter configuration data. The Rosemount Commissioning the transmitter on the bench before installation using a Field Communicator or AMS Device Manager ensures that all transmitter components are in working order.

To commission on the bench, required equipment includes a power supply, a milliamp meter, and a Field Communicator or AMS Device Manager. Wire equipment as shown in Figure 2-1 and Figure 2-2. To ensure successful communication, a resistance of at least 250 ohms must be present between the Field Communicator loop connection and the power supply. Connect the Field Communicator leads to the terminals labeled “COMM” on the terminal block.

Set all transmitter hardware adjustments during commissioning to avoid exposing the transmitter electronics to the plant environment after installation.

When using a Field Communicator, any configuration changes made must be sent to the transmitter by using the Send key. AMS Device Manager configuration changes are implemented when the Apply button is clicked.

2.3.1 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. The Field Communicator or AMS Device Manager will prompt you to set the loop to manual when necessary. Acknowledging this prompt does not set the loop to manual. The prompt is only a reminder; set the loop to manual as a separate operation.

™

3051 Pressure Transmitters can be commissioned either before or after installation.

2.3.2 Wiring diagrams

Connect the equipment as shown in Figure 2-1 for 4–20 mA HART® or Figure 2-2 for 1-5 Vdc HART Low Power. To ensure successful communication, a resistance of at least 250 ohms must be present between the Field Communicator loop connection and the power supply. The Field Communicator or AMS Device Manager may be connected at “COMM” on the transmitter terminal block or across the load resistor.

Configuration

Reference Manual

00809-0100-4001, Rev KA

Connecting across the “TEST” terminals will prevent successful communication for 4–20 mA HART output.

Turn on the Field Communicator by pressing the ON/OFF key or log into AMS Device Manager. The Field Communicator or AMS Device Manager will search for a HART-compatible device and indicate when the connection is made. If the Field Communicator or AMS Device Manager fail to connect, it indicates that no device was found. If this occurs, refer to Section 5: Troubleshooting.

2.9.2 Set output (transfer function)

The Rosemount 3051 has two output settings: linear and square root. Activate the square root output option to make analog output proportional to flow. As input approaches zero, the Rosemount 3051 automatically switches to linear output in order to ensure a more smooth, stable output near zero (see

Figure 2-10).

For 4–20 mA HART output, the slope of the curve is unity (y = x) from 0 to 0.6 percent of the ranged pressure input. This allows accurate calibration near zero. Greater slopes would cause large changes in output (for small changes at input). From 0.6 to 0.8 percent, curve slope equals 42 (y = 42x) to achieve continuous transition from linear to square root at the transition point.

Note

For a flow turndown of greater than 10:1 it is not recommended to perform a square root extraction in the transmitter. Instead, perform the square root extraction in the system.

2.9.3 Rerange

The Range Values command sets each of the lower and upper range analog values (4 and 20 mA points and 1 and 5 Vdc points) to a pressure. The lower range point represents 0 percent of range and the upper range point represents 100 percent of range. In practice, the transmitter range values may be changed as often as necessary to reflect changing process requirements. For a complete listing of range & sensor limits, refer to “Range and sensor limits” on page 93.

Note

Transmitters are shipped from Emerson (zero to upper range limit).

Note

Regardless of the range points, the Rosemount 3051 will measure and report all readings within the digital limits of the sensor. For example, if the 4 and 20 mA points are set to 0 and 10 inH transmitter detects a pressure of 25 inH reading.

Select from one of the methods below to rerange the transmitter. Each method is unique; examine all options closely before deciding which method works best for your process.

 Rerange with a Field Communicator or AMS Device Manager only.  Rerange with a pressure input source and a Field Communicator or AMS Device Manager.  Rerange with a pressure input source and the local zero and span buttons (option D4).

If the transmitter security switch is ON, adjustments to the zero and span will not be able to be made. Refer to “Configure security and alarm” on page 44 for security information.

Rerange with a Field Communicator or AMS Device Manager only.

The easiest and most popular way to rerange is to use the Field Communicator only. This method changes the range values of the analog 4 and 20 mA points (1 and 5 Vdc points) independently without a pressure input. This means that when you change either the 4 or 20 mA setting, you also change the span.

An example for the 4–20 mA HART output:

If the transmitter is ranged so that

4 mA = 0 inH 20 mA = 100 inH

and you change the 4 mA setting to 50 inH

4 mA = 50 inH 20 mA = 100 inH

Note that the span was also changed from 100 inH 100 inH

O, and

O using the communicator only, the new settings are:

O, and

O to 50 inH2O, while the 20 mA setpoint remained at

To obtain reverse output, simply set the 4 mA point at a greater numerical value than the 20 mA point. Using the above example, setting the 4 mA point at 100 inH 0 inH

O will result in reverse output.

Rerange with a pressure input source and a Field Communicator or AMS Device Manager

Reranging using the Field Communicator and applied pressure is a way of reranging the transmitter when specific 4 and 20 mA points (1 and 5 Vdc points) are not calculated.

Configuration

Reference Manual

Note

The span is maintained when the 4 mA point (1 Vdc point) is set. The span changes when the 20 mA point (5 Vdc point) is set. If the lower range point is set to a value that causes the upper range point to exceed the sensor limit, the upper range point is automatically set to the sensor limit, and the span is adjusted accordingly.

Rerange with a pressure input source and the local zero and span buttons (option D4)

Reranging using the local zero and span adjustments (see Figure 2-11 on page 20) and a pressure source is a way of reranging the transmitter when specific 4 and 20 mA (1 and 5 Vdc) points are not known and a communicator is not available.

Config uration

Note

When you set the 4 mA (1 Vdc) point the span is maintained; when you set the 20 mA (5 Vdc) 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 the transmitter using the span and zero buttons, perform the following procedure:

1. Loosen the screw holding the certifications label on the top of the transmitter housing. Slide the label to expose the zero and span buttons. See Figure 2-11.

2. Apply the desired 4 mA (1 Vdc) pressure value to the transmitter. Push and hold the zero adjustment button for at least two seconds but no longer than 10 seconds.

3. Apply the desired 20 mA (5 Vdc) pressure value to the transmitter. Push and hold the span adjustment button for at least two seconds but no longer than 10 seconds.

2.9.4 Damping

The “Damp” command introduces a delay in the micro-processing which increases the response time of the transmitter; smoothing variations in output readings caused by rapid input changes. Determine the appropriate damping setting based on the necessary response time, signal stability, and other requirements of the loop dynamics within your system. The default damping value is 0.4 seconds and it can be set to any of ten pre-configured damping values between 0 and 25.6 seconds. See list below.

 0.00 second  0.05 second  0.10 second

 0.20 second  0.40 second  0.80 second

 1.60 seconds  3.20 seconds  6.40 seconds

 12.8 seconds  25.6 seconds

The current damping value can be determined by executing the Field Communicator Fast Keys or going to Configure in AMS Device Manager.
