Reference Manual 00809-0100-4808, Rev CA June 2008 Rosemount 3051N Electrical shock can result in death or serious injury. • FAILURE MODE ALARM Avoid contact with the leads and terminals. High voltage that may be present on leads can cause electrical shock. 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.

Reference Manual 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.

Reference Manual 00809-0100-4808, Rev CA June 2008 REVIEW CONFIGURATION DATA HART Comm 1, 5 Rosemount 3051N 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.
PAGE 20
Reference Manual 00809-0100-4808, Rev CA June 2008 Rosemount 3051N 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 H2O on a range code 1 Rosemount 3051N, and the transmitter detects a pressure of 25 inH2O, it digitally outputs the 25 inH2O reading and a 250% of span reading. However, there may be up to ±5.

Reference Manual Rosemount 3051N 00809-0100-4808, Rev CA June 2008 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. Rerange with a Pressure Input Source and a Communicator HART Comm. 1, 2, 3, 1, 2 Reranging using the communicator and a pressure source or process pressure is a way of reranging the transmitter with a pressure input.
PAGE 23
Reference Manual 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.

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.

Reference Manual 00809-0100-4808, Rev CA June 2008 Rosemount 3051N 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.

Reference Manual 00809-0100-4808, Rev CA June 2008 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.

Reference Manual 00809-0100-4808, Rev CA June 2008 Rosemount 3051N GENERAL 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.
PAGE 39
Reference Manual 00809-0100-4808, Rev CA June 2008 Rosemount 3051N NOTE For steam service, do not blow down impulse piping through the transmitter. Flush the lines with the blocking valves closed and refill the lines with water before resuming measurement. NOTE When the transmitter is mounted on its side, position the Coplanar process flange to ensure proper venting or draining. Keep drain/vent connections on the bottom for gas service and on the top for liquid service.

Diagnostic Messages In addition to the output, the LCD meter displays abbreviated operation, error, and warning messages for troubleshooting the transmitter. Messages appear according to their priority, with normal operating messages appearing last. To determine the cause of a message, use a HART Communicator to further interrogate the transmitter.
PAGE 72
Reference Manual 00809-0100-4808, Rev CA June 2008 Rosemount 3051N Some non-volatile memory faults are user-addressable. Use a HART Communicator to diagnose the error and determine if it is repairable. Any error message that ends in “FACTORY” is not repairable. In cases of non user-addressable errors, you must replace the transmitter. Contact Rosemount Nuclear Instruments Inc. at (952) 949-5210 if you need assistance. FAIL ELECT The transmitter electronics board is malfunctioning due to an internal fault.

Reference Manual 00809-0100-4808, Rev CA June 2008 Operation Rosemount 3051N Normal operation messages appear on the LCD meter to confirm actions or inform you of transmitter status. Operation messages are displayed with other transmitter information, and warrant no action to correct or alter the transmitter settings. ZERO PASS The zero value, set with the local zero adjustment button, has been accepted by the transmitter, and the output should change to 4 mA.

Reference Manual 00809-0100-4808, Rev CA June 2008 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.

Reference Manual 00809-0100-4808, Rev CA June 2008 Rosemount 3051N CONNECTIONS AND HARDWARE 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.

Reference Manual 00809-0100-4808, Rev CA June 2008 Rosemount 3051N 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.

Reference Manual 00809-0100-4808, Rev CA June 2008 Rosemount 3051N 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.

Reference Manual 00809-0100-4808, Rev CA June 2008 Rosemount 3051N The touch screen should be contacted by blunt items only, preferably the stylus included with the Rosemount 375 Field Communicator. The use of sharp instruments, such as screwdrivers, can cause failure of the touch screen interface. Repair of the touch screen requires replacement of the entire Rosemount 375 Field Communicator display assembly, which is possible only at an authorized service center.
