Instructions for settingtransmitter switches (prior to installation) and explanations of softwarefunctions are provided in this section.Fast key sequences are listed for each software function. Please refer toAppendices A and B for more information on fast key sequences and othercommunicator operations.SAFETY MESSAGESWarnings ()Procedures and instructions in this section that raise potential safety issuesare indicated by a warning symbol ( ). Refer to the following warningmessages before performing an operation preceded by this symbol.Explosions can result in death or serious injury. Before connecting a communicator inan explosive atmosphere, make sure the instruments in the loop are installed inaccordance with intrinsically safe or nonincendive field wiring practices.Commissioning theTransmitter on the BenchCommissioning consists of testing the transmitter, testing the loop, andverifying transmitter configuration data. Rosemount 1151 Smart PressureTransmitters may be commissioned either before or after installation. Werecommend commissioning the transmitter on the bench before installation.This ensures that all transmitter components are in good working order andheightens familiarity with the device.To avoid exposing the transmitter electronics to the plant environment afterinstallation, set the failure mode and transmitter security switches during thecommissioning stage on the bench.Setting HardwareSwitcheswww.rosemount.comThe Rosemount 1151 Smart Pressure Transmitter contains hardwareswitches that provide user-selectable operation of the failure mode andtransmitter security. The switches are located on the electronics assembly justinside the electronics housing cover, as shown in Figure 2-1.
Reference Manual00809-0100-4593, Rev CAJune 2007Rosemount 1151Fail Safe Mode SwitchFigure 2-1.Transmitter Switch Locations.Transmitter Security SwitchNOTEUser-selectable switches areshown in default positionFailure Mode Alarm SwitchAs part of its normal operation, the Rosemount 1151 Smart continuouslymonitors its own operation. This automatic diagnostic routine is a timed seriesof checks repeated continuously.The electronics faceplate (Part No. 01151-0934-xxxx) has HI and LOuser-selectable failure mode settings. If the diagnostic routine detects a failurein the transmitter in analog output, the transmitter either drives its outputbelow 3.8 mA or above 21.0 mA, depending on the position of the failuremode alarm switch.NOTEWith multidrop (digital) output, the analog output remains at 4 mA, even whena diagnostic failure is detected. This is true for both the HI and LO fail modeswitch settings. A bit is enabled in the digital word to indicate a diagnosticfailure.Transmitter Security (Write-Protection Switch)Once the transmitter has been configured, it may be desirable to protect theconfiguration data from changes. The electronics assembly is equipped with aswitch labeled SECURITY. Figure 2-1 shows the switch location on the circuitside of the electronics housing. In the ON position, the switch prevents theaccidental or deliberate change of configuration data. To enable the sendingof configuration data, simply return the transmitter security switch to the OFFposition.NOTEThe transmitter security switch must be in the OFF position beforeconfiguration changes can be made to the transmitter configuration.2-2
Reference Manual00809-0100-4593, Rev CAJune 2007Commissioning theRosemount 1151 with aHART-BasedCommunicatorRosemount 1151Before putting the Rosemount 1151 Smart Pressure Transmitter intooperation, commission the instrument using a HART-based communicator.To commission on the bench, connect a 17 to 45 V dc power supply and acurrent meter, such as the Rosemount 282 Validator. Make connections asshown in Figure 2-2. The power supplied to the transmitter should not dropbelow the transmitter lift-off voltage. If the transmitter is being configuredwhen the power drops below the lift-off voltage, the configuration informationmay not be interpreted correctly by the transmitter.NOTETo enable communication, a resistance of at least 250 Ω must be presentbetween the communicator loop connection and the power supply.Wiring Diagrams(Bench Hook-up)After the bench equipment is connected as shown in Figure 2-2, turn on theHART-based communicator by pressing the ON/OFF key. The communicatorwill search for a HART-compatible device and will indicate when theconnection is made. If the connection is not made, the communicator willindicate that no device was found. If this occurs, refer to Section 4Troubleshooting.Figure 2-2. Bench Hook-up.24 V dcPowerSupplyRL 250 CurrentMeterNOTEAn alternate location to connect an ammeter is on the set of terminals labeled“TEST.” Connect the positive lead of the ammeter to the positive test terminal,and the negative lead of the ammeter to the negative test terminal.Testing the Equipmentand the LoopTest functions verify that the transmitter, the communicator, and the loop arein good working order. Testing is recommended whenever component failureor a problem with loop performance is suspected.Communicator TestA communicator test is performed to ensure the communicator is workingproperly. Both the HART Communicator 275 and the Rosemount 268Communicator perform self-tests after being turned on. If a problem isdetected, the communicator will list a diagnostic message. Refer toAppendices A and B for diagnostic messages associated with thecommunicator.2-3
Reference Manual00809-0100-4593, Rev CAJune 2007Rosemount 1151Transmitter TestHART Comm.1, 2, 1, 1Rosemount 268F2, F2Although the Rosemount 1151 Smart Pressure Transmitter performscontinuous self-diagnostics, a more extensive diagnostic routine can beinitiated with the transmitter test function. The transmitter test routine canidentify an electronics failure.If the transmitter test detects a problem, messages to indicate the source ofthe problem are displayed.Loop TestHART Comm.1, 2, 2Rosemount 268F2, F3The loop test allows verification of the output of the transmitter, the integrity ofthe loop, and the operation of any recorders or similar devices. Ifcommissioning the transmitter on the bench, repeat this test after thetransmitter has been installed in the field.A reminder appears to set the loop to manual. Do so and proceed. The nextdisplay selects a discrete milliampere transmitter output level. To commandthe transmitter to output 4 mA, for example, select 4 mA. Check the currentmeter installed in the test loop to verify that it reads 4 mA. If so, end the looptest. If the output is not 4 mA, then the receiving meter is malfunctioning or thetransmitter requires a digital trim as described on page 2-12.Review Configuration DataHART Comm.1, 5Rosemount 268Review KeyReview of the transmitter factory configuration data is recommended.Checking the Transmitter OutputHART Comm.2Rosemount 268PVProcess variable readings can be obtained in engineering units andmilliamperes. If the milliampere display does not agree with the actual loopreading given by a multimeter, a 4–20 mA trim is required.The last step of start-up and commissioning is to check the transmitter output.Obtain process variable readings in engineering units and milliamperes. If thisdisplay does not agree with the actual loop reading given by a multimeter, a4–20 mA trim is required (see page 2-19).Range PointsHART Comm.1, 3, 3Rosemount 268F3, F2, F1The Rosemount 1151 Smart 4 and 20 mA range points can be viewed andedited with these fast key sequences.2-4

This data flowcan 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 understoodby the microprocessor (Analog-to-Digital Signal Conversion).3. Corrections are performed in the microprocessor to obtain a digitalrepresentation of the process input (Digital PV).4. The Digital PV is converted to an analog value(Digital-to-Analog Signal Conversion).2-5

Both the HARTCommunicator 275 and the Rosemount 268 will prompt for this setting whennecessary. Keep in mind that simply acknowledging this prompter does notset the loop to manual. It is only a reminder; the loop must be set to manual asa separate operation.Change Non-Output Related InformationThe Rosemount 1151 Smart contains several configuration parameters thatdo not directly affect the transmitter output. These parameters include: Date Descriptor Message Meter typeSending Data to the TransmitterHART Comm.NoteRosemount 268F3, F4Whenever transmitter configuration data is updated with a HART-basedcommunicator, the entered data must be sent to the transmitter memory.NOTEDepending on the task, an option to enter the data (or end changes and enterthe data) will appear at the end of the configuration function. Follow theon-screen prompts to complete the send data function.Review the transmitter memory to ensure that configuration changes havebeen entered.Configure the AnalogOutput ParametersSetting UnitsHART Comm.1, 3Rosemount 268F3, F2By setting the output units, a process can be monitored using the specifiedunits. This is important if a plant uses units which differ from those preset byRosemount Inc. Output units can be selected from among 14 output options: inH20 inHg ftH20 mmH20 mmHg psi bar mbar g/cm2 kg/cm2 Pa kPa torr atmRerangingOne of the most common configuration tasks involves reranging thetransmitter 4 and 20 mA points.2-7
Reference Manual00809-0100-4593, Rev CAJune 2007Rosemount 1151Reranging matches the transmitter range points with the applied processpressures. It can be performed three ways: using the communicator only,using the communicator and a reference pressure, or using the integral zeroand span buttons and a reference pressure.To decide which method is appropriate, consider the following: Reranging with only the communicator changes the analog 4 and 20mA points independently without a pressure input.This means that when you change either the 4 or 20 mA setting, you alsochange the span. For instance:If the transmitter is ranged so that4 mA 0 inH2O, and20 mA 100 inH2O,and you change the 4 mA setting to 50 inH2O using the communicator only,the new settings are:4 mA 50 inH2O, and20 mA 100 inH2O.Note that the span was also changed from 100 inH2O to 50 inH2O, while the20 mA setpoint remained at 100 inH2O.To obtain reverse output, simply set the 4 mA point at a greater numericalvalue than the 20 mA point. Using the above example, setting the 4 mA pointat 100 inH2O and the 20 mA point at 0 inH2O will result in reverse output.NOTEThe 4 and 20 mA output is based on the transmitter's existing digitalcalibration. Before reranging with the keypad, make sure the transmitter iscorrectly interpreting the process variable input. To match the transmitter'sreading in engineering units to plant standard, use the sensor trim functionunder “Digital Trim” in this section. Reranging with a pressure input and the communicator maintains thesame analog span. Reranging with a pressure input and the zero and span buttonsmaintains the same analog span.For instance, if the transmitter is ranged so that:4 mA 0 inH2O, and20 mA 100 inH2O,and you then change the 4 mA setting to 50 inH2O using the communicator (orbuttons) and a pressure input, the new settings are:4 mA 50 inH2O20 mA 150 inH2OThe 100 inH2O span is maintained.It is also important to note that when using a pressure source, the 4 and 20mA setpoints are based on the transmitter’s interpretation of the pressureinput provided. It is possible that when a plant standard is input, thetransmitter reads it as a slightly different value. Although the 4 and 20 mAsetpoints will operate properly within these applied settings, the transmitter’sdigital output in engineering units may indicate a slightly different value.2-8
Reference Manual00809-0100-4593, Rev CAJune 2007Rosemount 1151The sensor trim function under “Digital Trim” can be used to match thetransmitter’s reading in engineering units to your plant standard, therebyeliminating any discrepancy.NOTEReranging only the 4 mA or the 20 mA with a pressure input will maintain theinitial span width.NOTEDo not rearing the transmitter such that the 4 and 20 mA range points—upperrange value (URV) and lower range value (LRV)—are outside the high andlow digital sensor trim values. To optimize performance, the digital trim spanshould be equal to or slightly greater than the 4–20 mA span.Reranging with a Communicator OnlyHART Comm.1, 2, 3, 1, 1Rosemount 268F
Rosemount 1151 Commissioning the Rosemount 1151 with a HART-Based Communicator Before putting the Rosemount 1151 Smart Pressure Transmitter into operation, commission the instrument using a HART-based communicator. To commission on the bench, connect a 17 to 45 V dc power supply and a current meter, such as the Rosemount 282 Validator.
