Section 1: Introduction Section 2: Installation Section 3: Commissioning Section 4: Operation and Maintenance Appendix A: Specifications and Reference Data Appendix B: Hazardous Area Approvals Appendix C: Safety Instrumented System (SIS) Transmitter The Rosemount Model 3144P Smart Temperature Transmitter is a microprocessor-based instrument that accepts input from a wide variety of sensors and transmits temperature data to a control system or transmitter interface. The transmitter combines Emerson Process Management reliability with the flexibility of digital electronics. The transmitter is ideal for applications that require high performance and/or remote communication. The AMS software and Model 275 HART® Communicator use HART protocol to interrogate, configure, test, and format the Model 3144P transmitter. Communication can be made with the transmitter from the control room, transmitter site, or across any other two points in the loop provided the loop contains 250 to 1100 ohms of resistance. Special dual-sensor features include Hot Backup®, sensor drift alert, first good, differential and average temperature measurements, and four simultaneous measurement variable outputs in addition to the analog output signal CONSIDERATIONS General www.rosemount.com Electrical temperature sensors, such as resistance temperature detectors (RTDs) and thermocouples (T/Cs), produce low-level signals proportional to temperature. The Model 3144P transmitter converts low-level sensor signals to a standard 4–20 mA dc signal. This current signal is then transmitted to the control room via two power/signal wires. Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Electrical Proper electrical installation is essential to prevent errors due to sensor lead resistance and electrical noise. Shielded cable should be used for best results in electrically noisy environments. The current loop must have between 250 and 1100 ohms resistance for HART communications. Refer to Figure 2-10 on page 2-11 for sensor and current loop connections. Environmental Temperature Effects The transmitter will operate within specifications for ambient temperatures between –40 and 185 °F (–40 and 85 °C). Heat from the process is transferred from the thermowell to the transmitter housing. If the expected process temperature is near or beyond specification limits, consider the use of additional thermowell lagging, an extension nipple, or a remote mounting configuration to isolate the transmitter from the process. Figure 1-1 describes the relationship between housing temperature rise and extension length. 60 (108) 50 (90) 40 (72) 815 °C (1500 °F) Oven Temperature 30 (54) 22 20 (36) 540 °C (1000 °F) Oven Temperature 10 (18) 3044-0123A Housing Temperature Rise, Above Ambient °C (°F) Figure 1-1. Model 3144P Transmitter Housing Temperature Rise versus Extension Length for a Test Installation. 250 °C (482 °F) Oven Temperature 0 3 4 3.6 5 6 7 8 Extension Length (in.) 9 Example: The maximum permissible housing temperature rise (T) can be calculated by subtracting the maximum ambient temperature (A) from the transmitter’s ambient temperature specification limit (S). For instance, suppose A = 40 °C. T=S-A T = 85 °C – 40 °C T = 45 °C For a process temperature of 540 °C (1004 °F), an extension length of 3.6 inches (91.4 mm) yields a housing temperature rise (R) of 22 °C (72 °F), which provides a safety margin of 23 °C (73 °F). A six-inch extension length (R = 10 °C (50 °F)) would offer a higher safety margin (35 °C (95 °F)) and would reduce temperature-effect errors but would probably require extra transmitter support. Gauge the requirements for individual applications along this scale. If a thermowell with lagging is used, the extension length may be reduced by the length of the lagging. 1-2 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Moist or Corrosive Environments The Model 3144P temperature transmitter has a highly reliable dual compartment housing designed to resist moisture and corrosion. The sealed electronics module is mounted in a compartment that is isolated from the terminal side conduit entries. O-ring seals protect the interior when the covers are properly installed. In humid environments, however, it is possible for moisture to accumulate in conduit lines and drain into the housing. NOTE Each transmitter is clearly marked with a tag indicating the approvals. Install the transmitter in accordance with all applicable installation codes and approval and installation drawings (see Appendix B: Product Certifications). Verify that the operating atmosphere of the transmitter is consistent with the hazardous locations certifications. Once a device labeled with multiple approval types is installed, it should not be reinstalled using any of the other labeled approval types. To ensure this, the approval label should be permanently marked to distinguish the used from the unused approval type(s). Mounting Take into account the need for access to the transmitter when choosing an installation location and position. Terminal Side of Electronics Housing Mount the transmitter so the terminal side is accessible. Allow adequate clearance for cover removal. Make wiring connections through the conduit openings on the bottom of the housing. Circuit Side of Electronics Housing Mount the transmitter so the circuit side is accessible. Provide adequate clearance for cover removal. Additional room is required for LCD installation. The transmitter may be mounted directly to or remotely from the sensor. Using optional mounting brackets, the transmitter may be mounted to a flat surface or to a two-inch diameter pipe (see “Optional Transmitter Mounting Brackets” on page A-8). Software Compatibility Replacement transmitters may contain revised software that is not fully compatible with the existing software in your HART communicator. Model 275 HART Communicators and AMS software containing device descriptors for the Models 3144 and 3244MV before December 2001 do not fully support the new features of the Model 3144P. The HART Communicator Field Device Revisions Dev v3,DD v2 should be loaded into the Model 275 HART Communicator to communicate with the new features of the Model 3144P. The Device Descriptors (DD) are available with new communicators or can be loaded into existing communicators at any Emerson Process Management Service Center. See Section 3: Commissioning for more device revisions information. 1-3 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P MODEL 3144P AND MODELS 3144 / 3244MV DIFFERENCES The following table identifies the differences between the Model 3144P and Models 3144 and 3244MV Temperature Transmitters.

Information that potentially raises safety issues is indicated by a warning symbol ( ). Please refer to the following safety messages before performing an operation preceded by this symbol. Warnings Explosions could result in death or serious injury: • Do not remove the transmitter cover in explosive atmospheres when the circuit is live. • Before connecting a HART communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices. • Verify that the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications. • Both transmitter covers must be fully engaged to meet explosion-proof requirements. Failure to follow these installation guidelines could result in death or serious injury: • Make sure only qualified personnel perform the installation. Process leaks could result in death or serious injury: • Install and tighten thermowells or sensors before applying pressure, or process leakage may result. • Do not remove the thermowell while in operation. Removing while in operation may cause process fluid leaks. Electrical shock could cause death or serious injury. If the sensor is installed in a high-voltage environment and a fault or installation error occurs, high voltage may be present on the transmitter leads and terminals: • www.rosemount.com Use extreme caution when making contact with the leads and terminals. Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P COMMISSIONING The Model 3144P must be configured for certain basic variables to operate. In many cases, all of these variables are pre-configured at the factory. Configuration may be required if the transmitter is not configured or if the configuration variables need revision. Commissioning consists of testing the transmitter and verifying transmitter configuration data. Model 3144P Series transmitters can be commissioned either before or after installation. Commissioning the transmitter on the bench before installation using a Model 275 HART Communicator or AMS ensures that all transmitter components are in working order. To commission on the bench, connect the transmitter and the HART Communicator or AMS as shown in Figure 2-10 on page 2-11. Make sure the instruments in the loop are installed according to intrinsically-safe or non-incendive field wiring practices before connecting a communication in an explosive atmosphere. Connect HART Communication leads at any termination point in the signal loop. For convenience, connect them to the terminals labeled “COMM” on the terminal block. Connecting across the “TEST” terminals will prevent successful communication. Avoid exposing the transmitter electronics to the plant environment after installation by setting all transmitter jumpers during the commissioning stage on the bench. When using a HART Communicator, any configuration changes made must be sent to the transmitter by using the “Send” key (F2). AMS configuration changes are implemented when the “Apply” button is clicked. For more information on using the model 275 HART Communicator with the Model 3144P transmitter, see Section 3: Commissioning. Figure 2-1. Installation Flowchart. START HERE Bench Calibration?

Switch Location LCD Meter Faceplate Fail Mode and Security Switch Failure Mode 3144- 0200G33A, 0001B01B Diagram of Switches LCD Connector Security Transmitter Security Switch The transmitter is equipped with a write-protect switch that can be positioned to prevent the accidental or deliberate change of configuration data. Failure Mode Switch The transmitter monitors itself during normal operation with an automatic diagnostic routine. If the diagnostic routine detects a sensor failure or a failure in the transmitter electronics, the transmitter goes into alarm (high or low, depending on the position of the failure mode switch). 2-3 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P The analog alarm and saturation values that the transmitter uses depend on whether it is configured to standard or NAMUR-compliant operation. These values are also custom-configurable in both the factory and the field using the HART Communications. The limits are Table 2-2. Values for standard and NAMUR operation • 21.0 ≤I ≤23 for high alarm • 3.5 ≤I ≤3.75 for low alarm Standard Operation (factory default) Fail High High Saturation Low Saturation Fail Low MOUNTING 21.75 mA ≤I ≤23.0 mA I ≥ 20.5 mA I ≤3.90 mA I ≤3.75 mA NAMUR-Compliant Operation Fail High High Saturation Low Saturation Fail Low 21 mA ≤I ≤23.0 mA I ≥ 20.5 mA I ≤3.8 mA I ≤3.6 mA If possible, mount the transmitter at a high point in the conduit run so moisture from the conduits will not drain into the housing. The terminal compartment could fill with water If the transmitter is mounted at a low point in the conduit run. In some instances, the installation of a poured conduit seal, such as the one pictured in Figure 2-3, is advisable. Remove the terminal compartment cover periodically and inspect the transmitter for moisture and corrosion. Figure 2-2.

Recommended Mounting with Drain Seal Sealing Compound Thermowell Sensor Hex Conduit for Field Wiring Poured Conduit Seal (Where Required) If mounting the transmitter directly to the sensor assembly, use the process shown in Figure 2-4. If mounting the transmitter apart from the sensor assembly, use conduit between the sensor and transmitter. The transmitter accepts male conduit fittings with 1/2–14 NPT, M20 × 1.5 (CM 20), PG 13.5 (PG 11), or JIS G1/2 threads (M20 × 1.5 (CM 20), PG 13.5 (PG 11), or JIS G1/2 threads are provided by an adapter). Make sure only qualified personnel perform the installation. The transmitter may require supplementary support under high-vibration conditions, particularly if used with extensive thermowell lagging or long extension fittings. Pipe-stand mounting, using one of the optional mounting brackets, is recommended for use in high-vibration conditions. 2-4 3144-0430B Union Coupling with Extension Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P INSTALLATION Typical North American Installation 1.

After-market installation of the LCD meter on a conventional Model 3144P transmitter requires a small instrument screwdriver and the LCD meter kit, which includes: • LCD meter assembly • Extended cover with cover O-ring in place • Captive screws (quantity 2) • 10-pin interconnection header Use the following procedure to install the LCD meter. Once the LCD meter is installed, configure the transmitter to recognize the meter option. Refer to “LCD Meter Options” on page 3-19. 1. If the transmitter is installed in a loop, set the loop to manual and disconnect the power. 2. Remove the housing cover from the electronics side of the transmitter. Do not remove the transmitter covers in explosive atmospheres if the circuit is live. 3. Ensure that the transmitter security mode switch is set to the Off position. If transmitter security is On, then you will not be able to configure the transmitter to recognize the LCD meter. If security On is desired, first configure the transmitter for the LCD meter and then install the meter. 4. Insert the interconnection header in the 10-pin socket on the face of the electronics module. Insert the pins into the electronics LCD interface. 5. Orient the meter. The meter can be rotated in 90-degree increments for easy viewing. Position one of the four 10-pin sockets on the back of the meter to accept the interconnection header. 6. Attach the LCD meter assembly to the interconnection pins. Thread and tighten the LCD meter screws into the holes on the electronics module. 7. Attach the extended cover; tighten at least one-third turn after the O-ring contacts the transmitter housing. Both transmitter covers must be fully engaged to meet explosion proof requirements. 8. Apply power. NOTE Observe the following LCD meter temperature limits: Operating:–4 to 185 °F (–20 to 85 °C) Storage:–50 to 185 °F (–45 to 85 °C) 2-8 Reference Manual 00809-0100-4021, Rev BA April 2003 Multichannel Installations Model 3144P You can connect several transmitters to a single master power supply (see Figure 2-7). In this case, the system may be grounded only at the negative power supply terminal. In multichannel installations where several transmitters depend on one power supply and the loss of all transmitters would cause operational problems, consider an uninterrupted power supply or a back-up battery. The diodes shown in Figure 2-7 prevent unwanted charging or discharging of the back-up battery. Figure 2-7. Multichannel Installations.

Signal wiring does not need to be shielded, but twisted pairs should be used for the best results. Do not run unshielded signal wiring in conduit or open trays with power wiring or near heavy electrical equipment. High voltage may be present on the leads and may cause electrical shock. To wire the transmitter for power, follow the steps below. 1. Remove the transmitter covers. Do not remove the transmitter covers in an explosive atmosphere when the circuit is live. 2. Connect the positive power lead to the terminal marked “+” and the negative power lead to the terminal marked “–” as shown in Figure 2-8. Crimped lugs are recommended when wiring to screw terminals. 3. Tighten the terminal screws to ensure that good contact is made. No additional power wiring is required. 4. Replace the transmitter covers. Both transmitter covers must be fully engaged to meet explosion-proof requirements. NOTE Do not apply high voltage (e.g., ac line voltage) to the transmitter terminals. Abnormally high voltage can damage the unit.

You can use these RTDs in 3-wire configurations by leaving the unneeded leads disconnected and insulated with electrical tape. *** Typical wiring configuration of a Rosemount dual-element RTD is shown (R=Red, W=White, G=Green, B=Black) Sensor Connections Figure 2-9 on page 2-10 shows the correct sensor wiring connections to the transmitter sensor terminals. To ensure an adequate sensor connection, anchor the sensor lead wires beneath the flat washer on the terminal screw. Do not remove the transmitter cover in explosive atmospheres if the circuit is live. Both transmitter covers must be fully engaged to meet explosion-proof requirements. Use extreme caution when making contact with the leads and terminals. RTD or Ohm Inputs If the transmitter is mounted remotely from a 3- or 4-wire RTD, it will operate within specifications, without recalibration, for lead wire resistances of up to 10 ohms per lead (equivalent to 1,000 feet of 20 AWG wire). In this case, the leads between the RTD and transmitter should be shielded. If using only two leads (or a compensation loop lead wire configuration), both RTD leads are in series with the sensor element, so significant errors can occur if the lead lengths exceed one foot of 20 AWG wire. For longer runs, attach a third or fourth lead as described above. To eliminate 2-wire lead resistance error, the 2-wire offset command can be used. This allows the user to input the measured lead wire resistance, resulting in the transmitter adjusting the temperature to correct the error. 2-10 3144-0000F05A B Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Thermocouple or Millivolt Inputs For direct-mount applications, connect the thermocouple directly to the transmitter. If mounting the transmitter remotely from the sensor, use appropriate thermocouple extension wire. Make connections for millivolt inputs with copper wire. Use shielding for long runs of wire. NOTE The use of two grounded thermocouples with a dual option Model 3144P transmitter is not recommended. For applications in which the use of two thermocouples is desired, connect either two ungrounded thermocouples, one grounded and one ungrounded thermocouple, or one dual element thermocouple. Power/Current Loop Connections Use copper wire of a sufficient size to ensure that the voltage across the transmitter power terminals does not go below 12.0 V dc. 1. Connect the current signal leads as shown in Figure 2-10. 2. Recheck the polarity and correctness of connections. 3. Turn the power ON. For information about multichannel installations, refer to page 2-14. NOTE Do not connect the power/signal wiring to the test terminal. The voltage present on the power/signal leads may burn out the reverse-polarity protection diode that is built into the test terminal. If the test terminal’s reverse polarity protection diode is burned out by the incorrect power/signal wiring, the transmitter can still be operated by jumping the current from the test terminal to the “–” terminal. See “Test Terminal” on page 4-3 for use of the terminal. Power/Signal Terminals The signal wire may be grounded at any point or left ungrounded. 250 ≤RL ≤1100 or* Power Supply AMS software or a HART Communicator can be connected at any termination point in the signal loop. The signal loop must have between 250 and 1100 ohms load for communications. 3144-0000A04A Figure 2-10. Connecting a Communicator to a Transmitter Loop. 2-11 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P POWER SUPPLY An external power supply is required to operate the Model 3144P (not included). The input voltage range of the transmitter is 12 to 42.4 V DC. This is the power required across the transmitter power terminals. The power terminals are rated to 42.4 V DC. With 250 ohms of resistance in the loop, the transmitter will require a minimum of 18.1 V DC for communication. The power supplied to the transmitter is determined by the total loop resistance and should not drop below the lift-off voltage. The lift-off voltage is the minimum supply voltage required for any given total loop resistance. See Figure 2-11 to determine the required supply voltage. If the power drops below the lift-off voltage while the transmitter is being configured, the transmitter may output incorrect information. The dc power supply should provide power with less than 2% ripple. The total resistance load is the sum of the resistance of the signal leads and the load resistance of any controller, indicator, or related piece of equipment in the loop. Note that the resistance of intrinsic safety barriers, if used, must be included. NOTE Do not allow the voltage to drop below 12.0 V dc at the transmitter terminals when changing transmitter configuration parameters, or permanent damage to the transmitter could result. Maximum Load = 40.8 X (Supply Voltage - 12.0) Load (Ohms) Figure 2-11. Load Limits. 4–20 mA dc 1240 1100 1000 750 500 Operating Region 250 0 10 Surges/Transients 20 30 40 42.4 12.0 Supply Voltage (V dc) The transmitter will withstand electrical transients of the energy level usually encountered in static discharges or induced switching. However, high-energy transients, such as those induced in wiring from nearby lightning strikes, can damage both the transmitter and the sensor. To protect against high-energy transients, install the integral transient protection board (option code T1) or the Rosemount Model 470 Transient Protector. The integral transient protection board is available as an ordered option or as an accessory. Refer to “ Transient Protection (Option Code T1)” on page A-16 for more information. The Model 470 transient protector is available only as an accessory. Refer to the Model 470 Transient Protector Product Data Sheet (document number 00813-0100-4191) for more information. 2-12 Reference Manual 00809-0100-4021, Rev BA April 2003 Grounding Model 3144P Shielding The currents in the leads induced by electromagnetic interference can be reduced by shielding. Shielding carries the current to ground and away from the leads and electronics. If the ends of the shields are adequately grounded, little current will actually enter the transmitter. If the ends of the shield are left ungrounded, a voltage is created between the shield and the transmitter housing and also between the shield and earth at the element end. The transmitter may not be able to compensate for this voltage, causing it to lose communication and/or go into alarm. Instead of the shield carrying the currents away from the transmitter, the currents will now flow through the sensor leads into the transmitter circuitry where they will interfere with the circuit operation. Shielding Recommendations The following are recommended practices are from API Standard 552 (Transmission Standard) section 20.7 and from field and laboratory testing. If more than one recommendation is given for a sensor type, start with the first technique shown or the technique that is recommended for the facility by its installation drawings. If the technique does not eliminate the transmitter alarms, try another technique. If all techniques unsuccessfully prevent transmitter alarms due to high EMI, contact a Emerson Process Management representative. Ungrounded Thermocouple, mV, and RTD/Ohm Inputs Option 1: recommended for ungrounded transmitter housing 1. Connect the signal wiring shield to the sensor wiring shield. 2. Ensure the two shields are tied together and electrically isolated from the transmitter housing. 3. Ground the shield at the power supply end only. 4. Ensure the shield at the sensor is electrically isolated from the surrounding fixtures that may be grounded. Sensor Wires 4–20 mA loop Shield ground point Connect shields together, electrically isolated from the transmitter 2-13 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Option 2: recommended for grounded transmitter housing 1. Connect the sensor wiring shield to the transmitter housing, provided the transmitter housing is grounded (see "Transmitter Housing"). 2. Ensure the shield at the sensor end is electrically isolated from surrounding fixtures that may be grounded. 3. Ground the signal wiring shield at the power supply end. Sensor Wires 4–20 mA loop Shield ground points Option 3 1. Ground the sensor wiring shield at the sensor, if possible. 2.

SAFETY MESSAGES Instructions and procedures 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 ( ). Please refer to the following safety messages before performing an operation preceded by this symbol. Warnings Explosions may result in death or serious injury. • Do not remove the instrument cover in explosive atmospheres when the circuit is live. • Before connecting a HART communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices. • Both covers must be fully engaged to meet explosion–proof requirements. Electrical shock could cause death or serious injury. If the sensor is installed in a high-voltage environment and a fault or installation error occurs, high voltage may be present on transmitter leads and terminals. • www.rosemount.com Use extreme caution when making contact with the leads and terminals. Reference Manual Model 3144P 00809-0100-4021, Rev BA April 2003 MODEL 275 HART COMMUNICATOR The HART Communicator exchanges information with the transmitter from the control room, the instrument site, or any wiring termination point in the loop. To facilitate communication, connect the HART Communicator in parallel with the transmitter (see Figure 2-11). Use the loop connection ports on the rear panel of the HART Communicator. The connections are non-polarized. Do not make connections to the serial port or the NiCad recharger jack in explosive atmospheres. Before connecting the HART communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices Updating the Model 275 HART Communication Software You may need to upgrade the Model 275 HART Communicator software to take advantage of the additional features available in the Model 3144P (field device revision 3). Perform the following steps to determine if an upgrade is required. 1. Turn on your communicator and select 4 Utility, then 5 Simulation. 2. Choose “Rosemount” from the list of manufacturers and “3144 Temp” from the list of models. 3. If the Fld Dev Rev choices include “Dev v3, DD v2,” an upgrade is not required. If the only choice is “Dev v1” or “Dev v2” (with any DD version), than the communicator should be upgraded. NOTE If you initiate communication with an improved Model 3144P using a communicator that only has a previous version of the transmitter device descriptors (DDs), the communicator will display the following message: NOTICE: Upgrade 275 software to access new XMTR functions. Continue with old description? If you select YES, the communicator will communicate properly with the transmitter using the existing transmitter DDs. However, new software features of the DD in the communicator will not be accessible. If you select NO, the communicator will default to a generic transmitter functionality. If YES is selected when the transmitter is already configured to utilize the new features of the improved transmitters (such as Dual Input configuration or one of the added sensor input types–DIN Type L or DIN Type U), the user will experience trouble communicating with the transmitter and will be prompted to turn the communicator off. To prevent this from happening, either upgrade the communicator to the latest DD or answer NO to the question above and default to the generic transmitter functionality. To see a list of enhancements included in the improved transmitters, see “Model 3144P and Models 3144 / 3244MV Differences” on page 1-3. 3-2 Reference Manual 00809-0100-4021, Rev BA April 2003 Menu Tree Model 3144P Figure 3-1 displays a complete Model 3144P menu tree for use with the Model 275 HART Communicator.

Apply changes made (see “Apply AMS Changes” on page 3-5). Average Temperature HART Fast Keys 1, 3, 1, 5, 4 The Model 3144P transmitter configured for dual-sensors can output and display the average temperature of any two inputs. Use the following procedure to configure the transmitter to measure the average temperature. First, configure Sensor 1 and Sensor 2 appropriately. Select 1 Device Setup, 3 Configuration, 2 Sensor Configuration, 1 Change Type and Conn. to set the sensor type and number of wires for Sensor 1. Repeat for Sensor 2.

NOTE If Sensor 1 and/or Sensor 2 should fail while PV is configured for average temperature and Hot Backup is not enabled, the transmitter will go into alarm. For this reason, when PV is Sensor Average it is recommended that Hot Backup be enabled when dual-element sensors are used or when two temperature measurements are taken from the same point in the process. If a sensor failure occures when Hot Backup is enabled while PV is Sensor Average, three scenarios could result: • If Sensor 1 fails, the average will only be reading from Sensor 2, the working sensor. • If Sensor 2 fails, the average will only be reading from Sensor 1, the working sensor. • If both sensors fail simultaneously, the transmitter will go into alarm and the status available (via HART) states that both Sensor 1 and Sensor 2 have failed. In the first two scenarios, where Hot Backup is enabled with PV set to Sensor Average, the 4-20 mA signal is not disrupted and the status available to the control system (via HART) specifes which sensor has failed. AMS For AMS, configure each sensor as indicated above. Right click on the device and select “Configuration Properties” from the menu. Select the Dual Sensor tab to configure the Average Temperature.In the Average Temperature box, Set the Ave Units to the desired output. Set damping if applicable. Apply changes made (see “Apply AMS Changes” on page 3-5). First-Good Configuration HART Fast Keys 1, 3, 1, 5, 5 The First Good device variable is useful for applications in which dual-sensors (or a single dual element sensor) are used in a single process. The first good variable will report the Sensor 1 value, unless Sensor 1 fails. When Sensor 1 fails, the Sensor 2 value will be reported as the first good variable. Once the first good variable has switched to Sensor 2, it will not revert back to Sensor 1 until a master reset occurs or “Suspend Non-PV alarms” is disabled. When the PV is mapped to first good and either Sensor 1 or Sensor 2 fails, the analog output will go to the alarm level, but the digital PV value read through the HART interface will still report the proper first good sensor value. If it is desired that the transmitter not go into analog output alarm while having the PV mapped to first good and Sensor 1 fails, enable “Suspend Non-PV Alarm” mode. This combination will prevent the analog ouput from going to the alarm level unless BOTH sensors fail. AMS For AMS, configure each sensor as indicated above. 3-11 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Right click on the device and select “Configuration Properties” from the menu. Select the Dual Sensor tab to configure the 1st Good. In the 1st Good box, set the 1st Good Units to the desired output. Set damping if applicable. Apply changes made (see “Apply AMS Changes” on page 3-5). Hot Backup Configuration HART Fast Keys 1, 3, 3, 4 The Config Hot BU command configures the transmitter to automatically use Sensor 2 as the primary sensor if Sensor 1 fails. With Hot Backup enabled, the primary variable (PV) must either be First Good or Sensor Average (see “Average Temperature” on page 3-10 for details on using Hot Backup when PV is Sensor Average). You can map Sensors 1 or 2 as the secondary variable (SV), tertiary variable (TV), or quaternary variable (QV). In the event of a primary variable (Sensor 1) failure, the transmitter enters Hot Backup mode and Sensor 2 becomes the PV. The 4–20 mA signal is not disrupted and a status is available to the control system (via HART) that Sensor 1 has failed. An LCD meter, if attached, also displays the failed sensor status. While configured to Hot Backup, if Sensor 2 fails while Sensor 1 is still operating properly, the transmitter continues to report the PV 4–20 mA analog output signal while a status is available to the control system (via HART) that Sensor 2 has failed. In Hot Backup mode, the transmitter will not revert back to Sensor 1 to control the 4–20 mA analog output until the Hot Backup mode is reset. Reset Hot Backup either by re-enabling via HART or by briefly powering down the transmitter. To set up and enable the Hot Backup feature for the Model 3144P transmitter, perform the following procedure: 1. Attach any two sensors to the transmitter as shown in Figure 2-12 on page 2-16. 2. From the Home screen, select 1 Device Setup, 3 Configuration, 1 Variable Mapping, 5 Variable Re-map to set primary, secondary, tertiary, and quaternary variables. The communicator displays the PV, SV, TV, and QV menus in succession. 3. Set PV as First Good or Sensor Average; set secondary, tertiary, and quaternary variables as desired. 4. Select OK after verifying the variable settings from the Variable Mapping menu. 5. Select OK to return the control loop to automatic control. Select HOME to return to the Home screen. 6. From the Home screen, select 1 Device Setup, 3 Configuration, 2 Sensor Configuration, 1 Change Type and Conn, 3 Sensor 1 Setup to configure Sensor 1. 7.

AMS For AMS, configure each sensor as indicated above. Right click on the device and select “Configuration.” Select “Configure Hot Backup.” The wizard will walk through the screens. Drift Alert Configuration HART Fast Keys 1, 3, 3, 5 The Drift Alert command allows the user to configure the transmitter to set a warning flag (via HART) or go into analog alarm when the temperature difference between Sensor 1 and Sensor 2 exceeds a user-defined limit. This feature is useful when measuring the same process temperature with two sensors, ideally when using a dual-element sensor. When Drift Alert mode is enabled, the user will set the maximum allowable difference, in engineering units, between Sensor 1 and Sensor 2. If this maximum difference is exceeded, a drift alert warning flag will be set. When configuring the transmitter for Drift Alert the user also has the option of specifying that the analog output of the transmitter go into alarm when sensor drifting is detected. NOTE The Drift Alert alarm cannot be enabled while Hot Backup is enabled. The Drift Alert warning, however, can be used simultaneously with Hot Backup. For information on configuring the transmitter for Hot Backup see page 3-12. To set up and enable the Drift Alert feature of the Model 3144P, perform the following procedure: 1. Attach any two sensors to the transmitter as shown in Figure 2-12 on page 2-16. 2. From the Home screen, select 1 Device Setup, 3 Configuration, 1 Variable Mapping, 5 Variable Re-map to set primary, secondary, tertiary, and quaternary variables. The communicator displays the PV, SV, TV, and QV menus in succession. 3. Select primary, secondary, tertiary, and quaternary variables as desired. 4. Select OK after verifying the variable settings from the Variable Mapping menu. 3-13 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P 5.

NOTE Enabling Drift Alert Option Warning only (Step 13) will set a flag (via HART) whenever the maximum acceptable difference between Sensor 1 and Sensor 2 has been exceeded. If it is desired for the the transmitter’s analog signal to go into alarm when Drift Alert is detected, select Alarm in Step 13. The Drift Alert alarm cannot be enabled when Hot Backup is enabled; The Drift Alert alarm can only be enabled if Hot Backup is disabled. AMS For AMS, configure each sensor as indicated above. Right click on the device and select “Configuration Properties” from the menu. Select the Dual Sensor tab to configure the Senosr Drift Alert. In the Drift Alert box, enable the Drift Alert Option. Enter the DrftLm limit and define the Drift Limit Units. Set damping if applicable. Apply changes made (see “Apply AMS Changes” on page 3-5). DEVICE OUTPUT CONFIGURATION Device output configuration contains PV range values, alarm and saturation, HART output, and LCD meter options. PV Range Values HART Fast Keys 1, 3, 4, 1 The PV URV and PV LRV commands, found in the PV Range Values menu screen, allow the user to set the transmitter’s lower and upper range values using limits of expected readings. See Table A-2 on page A-5 for unit and range setting limits. The range of expected readings is defined by the Lower Range Value (LRV) and Upper Range Value (URV). The transmitter range values may be reset as often as necessary to reflect changing process conditions. From the PV Range Values screen select 1 PV LRV to change the lower range value and 2 PV URV to change the upper range value. 3-14 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Reranging the transmitter sets the measurement range to the limits of the expected readings. Setting the measurement range to these limits maximizes transmitter performance; the transmitter is most accurate when operated within the expected temperature range for the application. The rerange functions should not be confused with the trim function. Although reranging the transmitter matches a sensor input to a 4-20 mA output, as in conventional calibration, it does not affect the transmitter’s interpretation of the input. AMS Right click on the device and select “Configuration Properties” from the menu. Select the Analog Output tab to define the upper and lower range values. From the Analog Input Range box, enter the URV and LRV. Apply changes made (see “Apply AMS Changes” on page 3-5). Process Variable Damping HART Fast Keys 1, 3, 4, 1, 3 The PV Damp command changes the response time of the 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 loop dynamics of the system. The default damping value is 5.0 seconds and can be reset to any value between 0 and 32 seconds. The value chosen for damping affects the response time of the transmitter. When set to zero (i.e., disabled), the damping function is off and the transmitter output reacts to changes in input as quickly as the intermittent sensor algorithm allows. Increasing the damping value increases transmitter response time. When damping is enabled, the transmitter will output a value at time (t) according to the following equation: Output(t) = Input(ts) – De(–t/damping) D = input step change at time t = 0 At the time to which the damping time constant is set, the transmitter output is at 63 percent of the input change; it continues to approach the input according to the damping equation above. For example, as illustrated in Figure 3-2, if the temperature undergoes a step change—from 100 degrees to 110 degrees, and the damping is set to 5.0 seconds, at 5.0 seconds, the transmitter outputs 106.3 degrees, or 63 percent of the input change, and the output continues to approach the input curve according to the equation above.. 3-15 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Figure 3-2.

If Sensor 1 is mapped as your primary variable, select the Sensor 1 tab. • Snr1 damp Apply changes made (see “Apply AMS Changes” on page 3-5). Alarm and Saturation HART Fast Keys 1, 3, 4, 2 The Alarm/Saturation command allows the user to view the alarm settings (Hi or Low). With this command it is also possible to change the alarm and saturation values. To change the alarm values and saturation values, select the value to be changed, either 1 Low Alarm, 2 High Alarm, 3 Low Sat., 4 High Sat, or 5 Preset Alarms. Enter the desired new value. It must fall within the guidelines given below. • The low alarm value must be between 3.50 and 3.75 mA • The high alarm value must be between 21.0 and 23.0 mA The low saturation level must be between the low alarm value plus 0.1 mA and 3.9 mA. Example: The low alarm value has been set to 3.7 mA. Therefore, the low saturation level, S, must be as follows: 3.8 ≤S ≤3.9 mA. The high saturation level must be between 20.5 mA and the high alarm value minus 0.1 mA. Example: The high alarm value has been set to 20.8 mA. Therefore, the low saturation level, S, must be as follows: 20.5 ≤S ≤20.7 mA. Preset alarms can either be 1 Rosemount or 2 NAMUR-compliant. Use the failure mode switch on the front side of the electronics (see “Switch Location” on page A-7) to set whether the output will be driven to high or low alarm in the case of failure. 3-16 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P AMS For AMS, configure each sensor as indicated above.

DEVICE INFORMATION Access the transmitter information variables online using the HART Communicator or other suitable communications device. The following is a list of transmitter information variables. These variables include device identifiers, factory-set configuration variables, and other information. A description of each variable, the corresponding fast key sequence, and a review of its purposes are provided. Tag HART Fast Keys 1, 3, 5, 1 The Tag variable is the easiest way to identify and distinguish between transmitters in multi-transmitter environments. Use it to label transmitters electronically according to the requirements of the application. The defined tag is automatically displayed when a HART-based communicator establishes contact with the transmitter at power-up. The tag may be up to eight characters long and has no impact on the primary variable readings of the transmitter. Date HART Fast Keys 1, 3, 5, 2 The Date command is a user-defined variable that provides a place to save the date of the last revision of configuration information. It has no impact on the operation of the transmitter or the HART-based communicator. Descriptor HART Fast Keys 1, 3, 5, 3 The Descriptor variable provides a longer user-defined electronic label to assist with more specific transmitter identification than is available with the tag variable. The descriptor may be up to 16 characters long and has no impact on the operation of the transmitter or the HART-based communicator. Message HART Fast Keys 1, 3, 5, 4 The Message variable provides the most specific user-defined means for identifying individual transmitters in multi-transmitter environments. It allows for 32 characters of information and is stored with the other configuration data. The message variable has no impact on the operation of the transmitter or the HART-based communicator. AMS Right click on the device and select “Configuration Properties” from the menu. Select the Device tab to enter alpahnumeric device information. Apply changes made (see “Apply AMS Changes” on page 3-5). 3-18 Reference Manual 00809-0100-4021, Rev BA April 2003 MEASUREMENT FILTERING Model 3144P 50/60 Hz Filter HART Fast Keys 1, 3, 6, 1 The 50/60 Hz Filter command sets the transmitter electronic filter to reject the frequency of the ac power supply in the plant. The 60 Hz normal, 50 Hz normal, 60 Hz fast, and 50 Hz fast modes can be chosen (normal mode is the default mode). On software release 5.3.4, the fast mode cannot be enabled. If fast mode is selected it will display the normal mode. NOTE In high noise environments, normal mode is recommended. Master Reset HART Fast Keys 1, 2, 1, 3 Master Reset resets the electronics without actually powering down the unit. It does not return the transmitter to the original factory configuration. AMS Right click on the device and select “Diagnostics and Calibration” from the menu. Choose “test,” then “Master Reset.” The wizard will perform the reset Intermittent Sensor Detect HART Fast Keys 1, 3, 6, 2 The following steps indicate how to turn the Intermittent Sensor Detect feature ON or OFF. When the transmitter is connected to a Model 275 HART Communicator, use the fast key sequence and choose ON or OFF (ON is the normal setting). AMS Right click on the device and select “Configuration Properties” from the menu. Select the Electronics tab. From the Measurement Filtering Box, configure the Intermit detect. The wizard will perform the reset Apply changes made (see “Apply AMS Changes” on page 3-5). Intermittent Threshold HART Fast Keys 1, 3, 6, 3 The threshold value can be changed from the default value of 0.2%. Turning the Intermittent Sensor Detect feature OFF or leaving it ON and increasing the threshold value above the default does not affect the time needed for the transmitter to output the correct alarm signal after detecting a true open sensor condition. However, the transmitter may briefly output a false temperature reading for up to one update in either direction (see Figure 3-4 on page 3-23) up to the threshold value (100% of sensor limits if Intermittent Sensor Detect is OFF). Unless rapid response rate is necessary, the suggested setting of the Intermittent Sensor Detect mechanism is ON with 0.2% threshold. 3-19 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Figure 3-3. Open Sensor Response 20 High Alarm 15 Normal open sensor responses When Intermittent Sensor Detect is OFF, a false temperature output is possible when an open sensor condition is detected. A false temperature output in either direction up to the threshold value (100 % of sensor limits if Intermittent Sensor Detect is OFF) is possible when an open sensor condition is detected. 10 5 0 0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 644-644_03 Transmitter Output (mA) 25 1.6 Time (seconds) Intermittent Sensor Detect (Advanced Feature) The Intermittent Sensor Detect feature is designed to guard against process temperature readings caused by intermittent open sensor conditions (an intermittent sensor condition is an open sensor condition that lasts less than one update). By default, the transmitter is shipped with the Intermittent Sensor Detect feature switched ON and the threshold value set at 0.2% of sensor limits. The Intermittent Sensor Detect feature can be switched ON or OFF and the threshold value can be changed to any value between 0 and 100% of the sensor limits with a HART communicator. Transmitter Behavior with Intermittent Sensor Detect ON When the Intermittent Sensor Detect feature is switched ON, the transmitter can eliminate the output pulse caused by intermittent open sensor conditions. Process temperature changes (∆T) within the threshold value will be tracked normally by the transmitter’s output. A ∆T greater than the threshold value will activate the intermittent sensor algorithm. True open sensor conditions will cause the transmitter to go into alarm. The threshold value of the Model 3144P should be set at a level that allows the normal range of process temperature fluctuations; too high and the algorithm will not be able to filter out intermittent conditions; too low and the algorithm will be activated unnecessarily. The default threshold value is 0.2% of the sensor limits. Transmitter Behavior with Intermittent Sensor Detect OFF When the Intermittent Sensor Detect feature is switched OFF, the transmitter tracks all process temperature changes, even if they are the consequence of an intermittent sensor. (The transmitter in effect behaves as though the threshold value had been set at 100%.) The output delay due to the intermittent sensor algorithm will be eliminated. AMS Right click on the device and select “Configuration Properties” from the menu. Select the Electronics tab. From the Measurement Filtering Box, configure the Intermit threshold. Apply changes made (see “Apply AMS Changes” on page 3-5). 3-20 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Open Sensor Holdoff HART Fast Keys 1, 3, 6, 4 The Open Sensor Holdoff option, at the normal setting, enables the Model 3144P to be more robust under heavy EMI conditions. This is accomplished through the software by having the transmitter perform additional verification of the open sensor status prior to activating the transmitter alarm. If the additional verification shows that the open sensor condition is not valid, the transmitter will not go into alarm. For users of the Model 3144P that desire a more vigorous open sensor detection, the Open Sensor Holdoff option can be changed to a fast setting. With this setting, the transmitter will report an open sensor condition without additional verification of the open condition. AMS Right click on the device and select “Configuration Properties” from the menu. Select the Electronics tab. From the Measurement Filtering Box box, configure the Open Snsr Holdoff. Apply changes made (see “Apply AMS Changes” on page 3-5). DIAGNOSTICS AND SERVICE Test Device HART Fast Keys 1, 2, 1 The Test Device command initiates a more extensive diagnostics routine than that performed continuously by the transmitter. The Test Device menu lists the following options: • 1 Loop test verifies the output of the transmitter, the integrity of the loop, and the operations of any recorders or similar devices installed in the loop. The ability to simulate an alarm is also available. See “Loop Test” below for more information. • 2 Self Test initiates a transmitter self test. Error codes are displayed if there is a problem. • 3 Master Reset sends out a command that restarts and tests the transmitter. A master reset is like briefly powering down the transmitter. Configuration data remains unchanged after a master reset. • 4 Status lists error codes. ON indicates a problem, and OFF means there are no problems. AMS Right click and select “Diagnostics and Calibration.” Choose “Test” and select “loop test,” “self test,” or “master reset.” Right-click on device and choose “status” to view errors. 3-21 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Loop Test HART Fast Keys 1, 2, 1, 1 The 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. To initiate a loop test, perform the following procedure: 1. Connect an external ampere meter to the transmitter. To do so, shunt the power to the transmitter through the meter at some point in the loop. 2. From the HOME screen, select 1 Device Setup, 2 Diag/Serv, 1 Test Device, 1 Loop Test before performing a loop test. Select OK after you set the control loop to manual. The communicator displays the loop test menu. 3. Select a discreet milliampere level for the transmitter to output. At the CHOOSE ANALOG OUTPUT prompt, select 1 4mA, 2 20mA, or select 4 Other to manually input a value between 4 and 20 milliamperes. Select Enter. It will indicate the fixed output. Select OK. 4. Check the installed transmitter in the test loop to verify that it reads the value that it was commanded to output. If the readings do not match, either the transmitter requires an output trim or the current meter is malfunctioning. After completing the test procedure, the display returns to the loop test screen and allows the user to choose another output value. To end the Loop Test, Select 5 End and Enter. The Test device screen will appear. The transmitter can simulate alarm conditions based on the transmitter’s current hardware and software alarm configurations. To initiate Simulation Alarm, perform the following procedure: 1. From the Home screen, select 1 Device Setup, 2 Diag/Serv, 1 Test Device, 1 Loop Test, 3 Simulate Alarm. 2. Based on the choosen alarm conditions, the transmitter will display an alarm. 3. To return the transmitter to normal conditions, select 5 End. AMS Right click and select “Diagnostics and Calibration.” Choose “Test” and select “Loop Test.” The loop test wizard will walk through the process to fix the output for either sensor 1 or 2. The trasmitter must be returned to normal conditions (turn off loop test) before placing back in process Right click and select “Diagnostics and Calibration.” Choose “Test” and select “Loop Test.” The loop test wizard will walk through the process to fix the analog output. From the loop test wizard screen choose “END.” A message will apppear indicating that it is OK to return to normal. 3-22 Reference Manual 00809-0100-4021, Rev BA April 2003 MULTIDROP COMMUNICATION Model 3144P Multidropping 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. Many of the Rosemount SMART FAMILY® transmitters can be multidropped. With the HART communications protocol, up to 15 transmitters can be connected on a single twisted pair of wires or over leased phone lines. The application of a multidrop installation requires consideration of the update rate necessary from each transmitter, the combination of transmitter models, and the length of the transmission line. Each transmitter is identified by a unique address (1–15) and responds to the commands defined in the HART protocol. Figure 3-4. Typical Multidropped Network Power Supply Impedance Power Supply 4–20 mA 250 Ω Handheld Terminal Computer or DCS HART Interface Model 3144P HART transmitter Figure 3-4 shows a typical multidrop network. Do not use this figure as an installation diagram. Contact Emerson Process Management product support with specific requirements for multidrop applications. A HART-based communicator can test, configure, and format a multidropped Model 3144P transmitter the same as in a standard point-to-point installation. NOTE The Model 3144P is set to address 0 at the factory, allowing it to operate 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 between 1 and 15. This change deactivates the 4–20 mA analog output, sending it to 4 mA. The failure mode current also is disabled. AMS Right click and select “Configuration Properties” from the menu screen. Select the “HART” tab. From here, assign the polling address. 3-23 Reference Manual 00809-0100-4021, Rev BA April 2003 USE WITH THE HART TRI-LOOP Model 3144P To prepare the Model 3144P transmitter with dual-sensor option for use with a Model 333 HART Tri-Loop, you must configure the transmitter to Burst Mode and set the process variable output order. In Burst Mode, the transmitter provides digital information for the four process variables to the HART Tri-Loop. The HART Tri-Loop divides the signal into separate 4–20 mA loops for up to three of the following choices: • primary variable (PV) • secondary variable (SV) • tertiary variable (TV) • quaternary variable (QV) When using the Model 3144P transmitter with dual-sensor option in conjunction with the HART Tri-Loop, consider the configuration of the differential, average, first good temperatures, Sensor Drift Alert, and Hot Backup features (if applicable). NOTE These procedures assume that the sensors and the transmitter are connected, powered, and functioning properly, and that a Model 275 HART Communicator is connected to the transmitter control loop and is communicating successfully. For communicator usage instructions, see “Commissioning” on page 2-2. Set the Transmitter to Burst Mode To set the transmitter to burst mode, follow the steps below. 1. From the Home screen, select 1 Device setup, 3 Configuration, 4 Device output configuration, 3 HART output, 4 Burst option to prepare to set the transmitter to burst command 3. The communicator displays the Burst option screen. 2. Select Process vars/current. The communicator returns to the HART output screen. 3. Select 3 Burst mode to prepare to enable Burst Mode. The communicator displays the Burst Mode screen. 4. Select On to enable Burst Mode. The communicator returns to the HART output screen. 5. Select Send to download the new configuration information to the transmitter. Set Process Variable Output Order To set the process variable output order, follow the steps below. 1. From the Home screen, select 1 Device setup, 3 Configuration, 1 Variable Mapping, 5 Variable Remapping. Select OK to set the control loop to manual. The communicator displays the Primary Variable screen. 2. Select the item to be set as the primary variable at the Select PV prompt. 3. Repeat step 2 for the SV, TV, and QV. The communicator displays the Variable mapping screen. 4. Select OK to accept the order to which the variables are mapped, or Abort to abort the entire procedure. 3-24 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P NOTE Take careful note of the process variable output order. You must configure the HART Tri-Loop to read the variables in the same order. 5. Select OK to return the control loop to automatic control. AMS Right click and select “Configuration” from the menu screen. Select “Set Variable Mapping” . The “Set Variable Mapping wizard” will go through the mapping procedure. Special Considerations To initiate operation between a Model 3144P transmitter with dual-sensor option and the HART Tri-Loop, consider the configuration of both the differential, average, first good temperatures, Sensor Drift Alert, and Hot Backup features (if applicable). Differential Temperature Measurement To enable the differential temperature measurement feature of a dual-sensor Model 3144P operating in conjunction with the HART Tri-Loop, adjust the range end points of the corresponding channel on the HART Tri-Loop to include zero. For example, if the secondary variable of the transmitter is to report the differential temperature, configure the transmitter accordingly (see “Set Process Variable Output Order” on page 3-24) and adjust the corresponding channel of the HART Tri-Loop so one range end point is negative and the other is positive. Hot Backup To enable the Hot Backup feature of a Model 3144P transmitter with dual-sensor option operating in conjunction with the HART Tri-Loop, ensure that the output units of the sensors are the same as the units of the HART Tri-Loop. Use any combination of RTDs or thermocouples as long as the units of both match the units of the HART Tri-Loop. Using the Tri-Loop to Detect Sensor Drift Alert The dual-sensor Model 3144P transmitter sets a failure flag (via HART) whenever a sensor failure occurs. If an analog warning is required, the HART Tri-Loop can be configured to produce an analog signal that can be interpreted by the control system as a sensor failure. Use these steps to set up the HART Tri-Loop to transmit sensor failure alerts. 1. Configure the dual-sensor Model 3144P variable map as shown . Variable Mapping PV SV TV QV Sensor 1 or Sensor Average Sensor 2 Differential Temperature As Desired 2. Configure Channel 1 of the HART Tri-Loop as TV (differential temperature). If either sensor should fail, the differential temperature output will be +9999 or –9999 (high or low saturation), depending on the position of the Failure Mode Switch (see “Failure Mode and Security Switch Locations” on page 2-5). 3-25 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P 3. Select temperature units for Channel 1 that match the differential temperature units of the transmitter. 4. Specify a range for the TV such as –100 to 100 °C. If the range is large, then a sensor drift of a few degrees will represent only a small percent of range. If Sensor 1 or Sensor 2 fails, the TV will be +9999 (high saturation) or –9999 (low saturation). In this example, zero is the midpoint of the TV range. If a ∆T of zero is set as the lower range limit (4 mA), then the output could saturate low if the reading from Sensor 2 exceeds the reading from Sensor 1. By placing zero in the middle of the range, the output will normally stay near 12 mA, and the problem will be avoided. 5. Configure the DCS so that TV < –100 °C or TV > 100 °C indicates a sensor failure and, for example, TV ≤–3 °C or TV ≥ 3 °C indicates a drift alert. See Figure 3-5. DIFFERENTIAL TEMPERATURE Figure 3-5.

Information that raises potential safety issues is indicated by a warning symbol ( ). Please refer to the following safety messages before performing an operation preceded by this symbol. Warning Explosions may result in death or serious injury. • Do not remove the instrument cover in explosive atmospheres when the circuit is live. • Before connecting a HART communicator in an explosive atmosphere, make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices. • Both transmitter covers must be fully engaged to meet explosion-proof requirements. Electrical shock could cause death or serious injury. If the sensor is installed in a high-voltage environment and a fault or installation error occurs, high voltage may be present on transmitter leads and terminals. • Use extreme caution when making contact with the leads and terminals. Failure to follow these installation guidelines could result in death or serious injury: • Make sure only qualified personnel perform the installation. Process leaks could result in death or serious injury: www.rosemount.com • Install and tighten thermowells or sensors before applying pressure, or process leakage may result. • Do not remove the thermowell while in operation. Removing while in operation may cause process fluid leaks. Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P CALIBRATION Calibrating the transmitter increases the precision of your measurement system. The user may use one or more of a number of trim functions when calibrating. To understand the trim functions, it is necessary to understand that smart transmitters operate differently from analog transmitters. An important difference is that smart transmitters are factory-characterized; they are shipped with a standard sensor curve stored in the transmitter firmware. In operation, the transmitter uses this information to produce a process variable output, dependent on the sensor input. The trim functions allow the user to make adjustments to the factory-stored characterization curve by digitally altering the transmitter’s interpretation of the sensor input. Calibration of the Model 3144P may include the following procedures: Trim the Transmitter • Sensor Input Trim: digitally alter the transmitter’s interpretation of the input signal • Transmitter Sensor Matching: generates a special custom curve to match that specific sensor curve, as derived from the Callendar-Van Dusen constants • Output Trim: calibrates the transmitter to a 4–20 mA reference scale • Scaled Output Trim: calibrates the transmitter to a user-selectable reference scale. The trim functions should not be confused with the rerange functions. Although the rerange command matches a sensor input to a 4–20 mA output—as in conventional calibration—it does not affect the transmitter’s interpretation of the input. One or more of the trim functions may be used when calibrating. The trim functions are as follows • Sensor Input Trim • Transmitter Sensor Matching • Output Trim • Output Scaled Trim Sensor Input Trim HART Fast Keys 1, 2, 2, 1, 1 The Sensor Trim command allows the user to digitally alter the transmitter’s interpretation of the input signal as shown in Figure 4-1 on page 4-3. The sensor trim command trims, in engineering (°F, °C, °R, K) or raw (Ω, mV) units, the combined sensor and transmitter system to a site standard using a known temperature source. Sensor trim is suitable for validation procedures or for applications that require profiling the sensor and transmitter together. Perform a sensor trim if the transmitters digital value for the primary variable does not match the plant’s standard calibration equipment. The sensor trim function calibrates the sensor to the transmitter in temperature units or raw units. Unless the site-standard input source is NIST-traceable, the trim functions will not maintain the NIST-traceability of your system 4-2 Reference Manual 00809-0100-4021, Rev BA April 2003 . Application: Linear Offset Solution: Single-Point Trim Method: 1. Connect sensor to transmitter. Place sensor in bath between range points. 2. Enter known bath temperature using the Model 275 HART Communicator. Application: Linear Offset and Slope Correction Solution: Two-Point Trim Method: 1. Connect sensor to transmitter.

Right click on the device and select “Diagnostics and Calibration” from the menu. Select “Calibrate,” then “Sensor Trim,” then “Sensor Input Trim.” The wizard will continue through the process. The transmitter may be restored to the factory default by selecting: “Diagnostics and Calibration,” “Sensor Trim,” “Revert to Factory Trim.” The wizard will recall the factory trim for a given sensor Apply changes made (see “AMS” on page 3-5). Active Calibrator and EMF Compensation HART Fast Keys 1, 2, 2, 1, 3 The transmitter operates with a pulsating sensor current to allow EMF compensation and detection of open sensor conditions. Because some calibration equipment requires a steady sensor current to function properly, the “Active Calibrator Mode” feature should be used when an Active Calibrator, which requires a constant sensor current, is connected. Enabling this mode will temporarily set the transmitter to provide steady sensor current unless two sensor inputs are configured. Disable this mode before putting the transmitter back into the process. Disabling this mode will set the transmitter back to pulsating current. “Active Calibrator Mode” is volatile and will automatically be disabled when a Master Reset is performed (via HART) or when power is cycled. EMF compensation allows the transmitter to provide sensor measurements that are not affected by unwanted voltages, which are typically due to thermal EMFs in the equipment connected to the transmitter or by some types of calibration equipment. If this equipment also requires steady sensor current, the transmitter must be set to “Active Calibrator Mode.” However, the steady current does not allow the transmitter to perform EMF compensation. As a result, a difference in readings between the Active Calibrator and actual sensor may exist. If a reading difference is experienced and the difference is greater than the plant’s accuracy specification allows, perform a sensor trim with “Active Calibrator Mode” disabled. In this case, an active calibrator capable of tolerating pulsating sensor current must be used or the actual sensors must be connected to the transmitter. When the Model 275 HART Communicator or AMS asks if an Active Calibrator is being used when the sensor trim routine is entered, select No. This will leave the “Active Calibrator Mode” disabled. Contact a Emerson Process Management representative for more information. Transmitter-Sensor Matching HART Fast Keys 1, 3, 2, 1, 1 The Model 3144P accepts Callendar-Van Dusen constants from a calibrated RTD schedule and generates a special custom curve to match that specific sensor Resistance vs. Temperature performance. Matching the specific sensor curve with the transmitter significantly enhances the temperature measurement accuracy. See the comparison below: 4-5 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P System Accuracy Comparison at 150 °C Using a PT 100 (α=0.00385) RTD with a Span of 0 to 200 °C Standard RTD Model 3144P Standard RTD Total System(1) ±0.10 °C ±1.05 °C ±1.05 °C Matched RTD Model 3144P Matched RTD Total System(1) ±0.10 °C ±0.18 °C ±0.21 °C (1) Calculated using root-summed-squared (RSS) statistical method TotalSystemAccuracy = ( TransmitterAccuracy ) 2 + ( SensorAccuracy ) 2 The following input constants, included with specially-ordered Rosemount temperature sensors, are required: R0 = Resistance at Ice Point Alpha = Sensor Specific Constant Beta = Sensor Specific Constant Delta = Sensor Specific Constant Other sensor may have “A,B, or C” values for constants.

Calibrate the analog output signal at regular intervals to maintain measurement precision. To perform a digital-to-analog trim, perform the following procedure: 1. From the HOME screen, select 1 Device setup, 2 Diag/Service, 2 Calibration, 2 D/A trim. Set the control loop to manual and select OK. 2. Connect an accurate reference meter to the transmitter at the CONNECT REFERENCE METER prompt. To do so, shunt the power to the transmitter through the reference meter at some point in the loop. Select OK after connecting the reference meter. 3. Select OK at the SETTING FLD DEV OUTPUT TO 4 MA prompt. The transmitter outputs 4.00 mA. 4. Record the actual value from the reference meter, and enter it at the ENTER METER VALUE prompt. The communicator prompts the user to verify if the output value equals the value on the reference meter. 5. If the reference meter value equals the transmitter output value, then select 1 Yes and go to step 6. If the reference meter value does not equal the transmitter output value, then select 2 No and go to step 4. 6. Select OK at the SETTING FLD DEV OUTPUT TO 20 MA prompt and repeat steps 4 and 5 until the reference meter value equals the transmitter output value. 7. Return the control loop to automatic control and select OK. AMS Right click on the device and select “Diagnostics and Calibration” from the menu. Select the “Calibrate” and choose the “D/A Trim.” This wizard will go through the required changes. Scaled Output Trim HART Fast Keys 1, 2, 2, 3 The Scaled D/A Trim command matches the 4 and 20 mA points to a user-selectable reference scale other than 4 and 20 mA (2–10 volts, for example). To perform a scaled D/A trim, connect an accurate reference meter to the transmitter and trim the output signal to scale as outlined in the ”Output Trim” procedure. AMS Right click on the device and select “Diagnostics and Calibration” from the menu. Select the “Calibrate” and choose the “Scaled D/A Trim.” This wizard will go through the required changes. 4-8 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P HARDWARE Diagnostics with HART Communicator If a malfunction is suspected despite the absence of a diagnostics message on the HART communicator display, follow the procedures described in Table 4-1 to verify that transmitter hardware and process connections are in good working order.

The transmitter features a modular design for easy maintenance. If a malfunction is suspected, check for an external cause before performing the diagnostics as discussed in this section. Test Terminal The test terminal, marked as TEST or (“T”) on the terminal block, and the negative (-) terminal accept MINIGRABBER™, or alligator clips, and facilitate in-process checks (see Figure 2-8 on page 2-10). The test and the negative terminals are connected across a diode through which the loop signal current passes. The current measuring equipment shunts the diode when connected across the test (T) and negative (-) terminals; so as long as the voltage across the terminals is kept below the diode threshold voltage, no current passes through the diode. To ensure that there is no leakage current through the diode while making a test reading, or while an indicating meter is connected, the resistance of the test connection or meter should not exceed 10 ohms. A resistance value of 30 ohms will cause an error of approximately 1.0 percent of reading. Sensor Checkout If the sensor is installed in a high-voltage environment and a fault condition or installation error occurs, the sensor leads and transmitter terminals could carry lethal voltages. Use extreme caution when making contact with the leads and terminals. To determine whether the sensor is at fault, either replace it with another sensor or connect a test sensor locally at the transmitter to test remote sensor wiring. Transmitters with Option Code C7 (Trim to Special Sensor), are matched to a specific sensor. Select any standard, off-the-shelf sensor for use with the transmitter, or consult the factory for a replacement special sensor/transmitter combination. Disassembling the Electronics Housing The transmitter is designed with a dual-compartment housing; one compartment contains the electronics module, and the other compartment contains all wiring terminals and the communication receptacles. Removing the Electronics Module The Model 3144P electronics module is located in the compartment opposite the wiring terminals. Use the following procedure to remove the electronics module. NOTE The electronics are sealed in a moisture-proof plastic enclosure referred to as the electronics module. The module is a non-repairable unit; The entire unit must be replaced if a malfunction occurs. 4-12 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P 1. Disconnect the power to the transmitter. 2. Remove the cover from the electronics side of the transmitter housing (see “ Transmitter Exploded View” on page A-7). Do not remove the covers in explosive atmospheres when the circuit is live. Remove the LCD meter, if applicable. 3. Loosen the two screws that anchor the electronics module assembly to the transmitter housing. 4. Firmly grasp the screws and assembly and pull it straight out of the housing, taking care not to damage the interconnecting pins. NOTE Note the transmitter’s security switch position (ON or OFF) and the failure mode switch position (LO or HI). If you are replacing the electronics module with a new one, make sure the security and alarm switch is set in the same position. Transmitter Security and Failure Mode Switches The transmitter security and failure mode switches are located on the front of the electronics module, as shown in “Switch Location” on page A-7. See “Mounting and Installation” on page 2-6 for more information. ASSEMBLING THE ELECTRONICS HOUSING Replacing the Electronics Module Use the following procedure to reassemble the electronics housing for the Model 3144P transmitter: 1. Examine the electronics module to ensure that the failure mode and transmitter security switches are in the desired positions. 2. Carefully insert the electronics module to mate the interconnecting pins with the necessary receptacles on the electronics board. 3. Tighten the two mounting screws. Replace the LCD meter, if applicable. 4. Replace the cover. Tighten 1/6 of a revolution after the cover begins to compress the O-ring. Both transmitter covers must be fully engaged to meet explosion proof requirements. LCD Meter Diagnostic Messages The LCD meter displays abbreviated diagnostic messages for troubleshooting the transmitter. To accommodate two-word messages, the display alternates between the first and second word. Some diagnostic messages have a higher priority than others, so messages appear according to their priority, with normal operating messages appearing last. The meter displays messages simultaneously on the Process Variable and Process Variable Unit lines as shown in “LCD Meter Faceplate” on page A-7. Messages on the Process Variable line refer to general device conditions, while messages on the Process Variable Unit line refer to specific causes for these conditions. A description of each diagnostic message follows. 4-13 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P [BLANK] If the meter does not appear to function, make sure the transmitter is configured for the meter option you desire. The meter will not function if the LCD Meter option is set to Not Used. FAIL -or- HDWR FAIL This message indicates one of several conditions including: • The transmitter has experienced an electronics module failure. • The transmitter self-test has failed. If diagnostics indicate a failure of the electronics module, replace the electronics module with a new one. Contact the nearest Emerson Process Management Field Service Center if necessary. SNSR 1 FAIL -or- SNSR 2 FAIL The transmitter has detected an open or shorted sensor condition. The sensor(s) might be disconnected, connected improperly, or malfunctioning. Check the sensor connections and sensor continuity. SNSR 1 SAT -or- SNSR 2 SAT The temperature sensed by the transmitter exceeds the sensor limits for this particular sensor type. HOUSG SAT The transmitter operating temperature limits (–40 to 185 °F (40 to 85 °C)) have been exceeded. LOOP FIXED During a loop test or a 4–20 mA output trim, the analog output defaults to a fixed value. The Process Variable line of the display alternates between the amount of current selected in milliamperes and “WARN.” The Process Variable Unit line toggles between “LOOP,” “FIXED,” and the amount of current selected in milliamperes. OFLOW The location of the decimal point, as configured in the meter setup, is not compatible with the value to be displayed by the meter. For example, if the meter is measuring a process temperature greater than 9.9999 degrees, and the meter decimal point is set to 4 digit precision, the meter will display an “OFLOW” message because it is only capable of displaying a maximum value of 9.9999 when set to 4 digit precision. HOT BU Hot Backup is enabled and Sensor 1 has failed. This message is displayed on the Process Variable line and is always accompanied by a more descriptive message on the Process Variable Unit line. In the case of a Sensor 1 failure with Hot Backup enabled, for example, the Process Variable line displays “HOT BU,” and the Process Variable Unit line alternates between “SNSR 1” and “FAIL.” 4-14 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P 3144-3144_03A, 03B Figure 4-3. Hot Backup Display. WARN DRIFT ALERT Drift Alert warning is enabled and the difference between Sensor 1 and Sensor 2 has exceeded the user-specified limit. One of the sensors may be malfunctioning. The Process Variable line displays “WARN” and the Process Variable Unit line alternates between “DRIFT” and “ALERT.” 3144-3144_03C, 03D Figure 4-4. Sensor Drift Alert Display. ALARM DRIFT ALERT The analog output is in alarm. Drift Alert alarm is enabled and the difference between Sensor 1 and Sensor 2 has exceeded the user-specified limit. The transmitter is still operating, but one of the sensors may be malfunctioning. The Process Variable line displays “ALARM” and the Process Variable Unit line alternates between “DRIFT” and “ALERT.” ALARM The digital and analog outputs are in alarm. Possible causes of this condition include, but are not limited to, an electronics failure or an open sensor. This message is displayed on the Process Variable line and is always accompanied by a more descriptive message on the Process Variable Unit line. In the case of a Sensor 1 failure, for example, the Process Variable line displays “ALARM,” and the Process Variable Unit line alternates between “SNSR 1” and “FAIL.” WARN The transmitter is still operating, but something is not correct. Possible causes of this condition include, but are not limited to, an out-of-range sensor, a fixed loop, or an open sensor condition. In the case of a Sensor 2 failure with Hot Backup enabled, the Process Variable line displays “WARN,” and the Process Variable Unit line alternates between “SNSR 2” and “RANGE.” 4-15 Reference Manual 00809-0100-4021, Rev BA April 2003 AMS Screens Diagnostic Messages Model 3144P AMS provides advanced diagnostic messages, as well as help screens for the messages. Using the help screens can provide quick reference to remedying the situation. The trouble shooting section for this manual can also be pasted in AMS to assist in quick and accurate troubleshooting reference. Alarms and Alerts Right click on the device and select “Process Variables”. This screen shows the sensor reading and status of the sensor and transmitters. If no alarms or alerts are activated, the screen will look like this: Sensor Failure When the transmitter has detected an open or shorted sensor condition, the sensor(s) might be disconnected, connected improperly, or malfunctioning. Check the Sensor connections and continuity. Replace the sensor if necessary. By right-clicking on the device and selecting “status,: the status screen appears. This screen shows an overview of the transmitter health. Red bars indicate system changes or that the transmitter is not working properly and should be investigated. 4-16 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Hot BackUp® Hot Backup is enabled and Sensor 1 or Sensor 2 has failed. The following is displayed on the Process Variable Screen. The suspect sensor should be investigated as soon as possible, and replaced as necessary. Sensor Drift Alert When the Drift Alert warning or alarm is enable, they indicate that the differences between Sensor 1 and Sensor 2 has exceeded the user-specified limit. One of the sensors may be malfunctioning. The sensors should both be investigated at the earliest opportunity.

Local Indication Optional five-digit LCD meter includes 0–100% bar graph. Digits are 0.4 inches (8 mm) high. Display options include engineering units (°F, °C, °R, K, ohms, and millivolts), percent, and milliamperes. The display can also be set to alternate between engineering units/milliamperes, Sensor 1/Sensor 2, Sensor 1/Sensor 2/Differential Temperature, and Sensor 1/Sensor2/Average Temperature. All display options, including the decimal point, may be reconfigured in the field using a Model 275 HART Communicator or AMS. Humidity Limits 0–100% relative humidity Transient Protection (option code T1) The transient protector helps to prevent damage to the transmitter from transients induced on the loop wiring by lightning, welding, heavy electrical equipment, or switch gears. The transient protection electronics are contained in an add-on assembly that attaches to the standard transmitter terminal block. Option code G1 external ground lug assembly is included with the Transient Protector option code T1.The transient protector has been tested per the following standard: • ASME B 16.5 (ANSI)/IEEE C62.41-1991 (IEEE 587)/ Location Categories A2, B3. 6kV/3kA peak (1.2 50 µS Wave 8 20 µS Combination Wave) 6kV/0.5kA peak (100 kHz Ring Wave) 4kV peak EFT (5 50 µS Electrical Fast Transient) • Loop resistance added by protector: 22 ohms max. • Nominal clamping voltages: 90 V (common mode), 77 V (normal mode) Temperature Limits Description Operating Limit Storage Limit Without LCD Meter –40 to 185 °F –40 to 85 °C –4 to 185 °F –20 to 85 °C –60 to 250 °F –50 to 120 °C –50 to 185 °F –45 to 85 °C With LCD Meter Turn-on Time Performance within specifications less than 5.0 seconds after power is applied to transmitter Failure Mode The Model 3144P features software and hardware failure mode detection. An independent circuit is designed to provide backup alarm output if the microprocessor hardware or software fails. A-2 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P The alarm levels are user-selectable using the failure mode switch. If failure occurs, the position of the hardware switch determines the direction in which the output is driven (HI or LO). The switch feeds into the digital-to-analog (D/A) converter, which drives the proper alarm output even if the microprocessor fails. The values at which the transmitter drives its output in failure mode depends on whether it is configured to standard, or NAMUR-compliant (NAMUR recommendation NE 43, June 1997) operation. The values for standard and NAMUR-compliant operation are as follows: Table A-1. Operation Parameters Linear Output: Fail High: Fail Low: Standard (1) NAMUR-Compliant(1) 3.9 ≤ I ≤20.5 21.75 ≤I ≤23 (default) I ≤3.75 3.8 ≤I ≤20.5 21.5 ≤I ≤23 (default) I ≤3.6 (1) Measured in milliamperes Custom Alarm and Saturation Levels Custom factory configurations of alarm and saturation levels are available for valid values with option code C1. These values can also be configured in the field using a HART Communicator. Physical Conduit Connections The standard field mount housing has ½–14 NPT conduit entries. Additional conduit entry type are available, including PG13.5 (PG11), M20 X 1.5 (CM20), or JIS G ½. When an of these additional entry types are ordered, adapters are placed in the standard field housing so these alternative conduit types fit correctly. See Dimensional drawings for increased dimensions. HART Communicator Connections HART communicator connections are permanently fixed to power/signal block.

Vibration Effect Transmitters tested to the following specifications with no effect on performance: Frequency Acceleration 10–60 Hz 60–2000 Hz 0.21 mm peak displacement 3g Self Calibration The analog-to-digital measurement circuitry automatically self-calibrates for each temperature update by comparing the dynamic measurement to extremely stable and accurate internal reference elements. Power Supply Effect Less than ±0.005% of span per volt RFI Effect Worst case RFI effect is equivalent to the transmitter’s nominal accuracy specification, according to Table on page A-5, when tested in accordance with IEC 61326, 10 V/m, 80 to 1000 MHz, with unshielded cable. CE Electromagnetic Compatibility Compliance Testing The Model 3144P meets all requirements listed under IEC 61326: Amendment 1, 1998. Emerson Process Management Conformance to Specifications For example, the Reference Accuracy distribution for the Model 3144P is shown to the right. Our Specification Limits are ± 0.10 °C, but, as the shaded area shows, approximately 68% of the units perform three times better than the limits. Therefore, it is very likely that you will receive a device that performs much better than our published specifications. Conversely, a vendor who “grades” product without using Process Control, or who is not committed to ± 3 performance, will ship a higher percentage of units that are barely within advertised specification limits. Typical Accuracy Lower Specification Limit –3σ –2σ 1σ 2σ 3σ Note: Accuracy distribution shown is for the Model 3144P, PT 100 RTD sensor, Range 0 to 100 °C. (1) Sigma (σ) is a statistical symbol to designate the standard deviation from the mean value of a normal distribution. A-4 –1σ Upper Specification Limit 3144-GRAPH A Rosemount product not only meets its published specifications, but most likely exceeds them. Advanced manufacturing techniques and the use of Statistical Process Control provide specification conformance to at least ± 3(1). Our commitment to continual improvement ensures that product design, reliability, and performance will improve annually.

Reference Accuracy Example When using a Pt 100 (α = 0.00385) sensor input with a 0 to 100 °C span: Digital Accuracy would be ±0.10 °C, D/A accuracy would be ±0.02% of 100 °C or ±0.02 °C, Total = ±0.12 °C. Differential Capability Exists Between Any Two Sensor Types (dual-sensor option) For all differential configurations, the minimum and maximum input range is X to +Y where: • X = Sensor 1 minimum – Sensor 2 maximum • Y = Sensor 1 maximum – Sensor 2 minimum. Digital Accuracy for Differential Configurations (dual-sensor option) • Sensor types are similar (e.g., both RTDs or both T/Cs): Digital Accuracy = 1.5 times worst case accuracy of either sensor type. • Sensor types are dissimilar (e.g., one RTD, one T/C): Digital Accuracy = Sensor 1 Accuracy + Sensor 2 Accuracy. A-5 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P Ambient Temperature Effect Transmitters may be installed in locations where the ambient temperature is between –40 and 85 °C (–40 and 185 °F). Each transmitter is individually characterized over this ambient temperature range at the factory in order to maintain excellent accuracy performance. The factory characterization technique is accomplished through extreme hot and cold temperature profiling with individual adjustment factors programmed into each transmitter. Transmitters automatically adjust for component drift caused by changing environmental conditions. Table A-3.

Although the Model 3144P is not certified for functional safety per IEC61508, a complete Failure Modes, Effects, and Diagnosis Analysis (FMEDA) was completed to determine the safe failure fraction (SFF) when using this device in a SIS application. FMEDA are the device characteristics that are taken into account when attempting to achieve functional safety certification per IEC61508 of a device. From the FMEDA, failure rates are determined for all temperature sensing device options. Furthermore, the Safe Failure Fraction is calculated for each of the four different input device configurations. The Model 3144P is an isolated 2-wire 4-20 mA SMART device classified as Type B according to IEC61508. It contains self-diagnostics and is programmed to send its output to either a high or low failure state upon internal detection of a failure. The analysis shows that the device has a safe failure fraction between 60 and 90% (assuming that the logic solver is programmed to detect over-scale and under-scale currents). The device has a safe failure fraction of over 90% when used with a temperature sensing device, such as thermocouple or RTD. The device can detect open and short circuit failures of these temperature sensing devices. Table C-1. Definitions Abbreviation λ H λL Description Fail High (1) Failure that will result in an output current that is higher than 20 mA Fail Low(1) Failure that will result in an output current that is lower than 4 mA λDU Fail Dangerous Undetected Failure that is dangerous and that is not being diagnosed by internal diagnostics SFF Safe Failure Fraction Fraction of the overall failure rate of a device that results in either a safe fault or a diagnosed unsafe fault. (1) Detected by the logic solver. www.rosemount.com Definition Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P FAILURE RATE DATA Model 3144P with and without a RTD The failure rates for the Model 3144P transmitter operating in 4-wire RTD mode, excluding the failure rates for the sensing device, are as follows: • λH = 32.85 * 10-9 failures per hour • λL = 351.96 * 10-9 failures per hour(1) • λDU = 74.29 * 10-9 failures per hour • SFF = 83.82%(2) If these are combined with failure rates for a closely coupled, shock protected, 4-wire RTD then the total failure rates for the temperature sensing subsystem are as follows: Model 3144P with and without a Thermocouple • λH = 32.85 * 10-9 failures per hour • λL = 2331.96 * 10-9 failures per hour (1) • λDU = 94.29 * 10-9 failures per hour • SFF = 96.17%(2) The failure rates for the Model 3144P transmitter operating in thermocouple mode, excluding the failure rates for the sensing device, are as follows: • λH = 32.85 * 10-9 failures per hour • λL = 344.16 * 10-9 failures per hour(1) • λDU = 74.29 * 10-9 failures per hour • SFF = 82.62% If these are combined with failure rates for a closely coupled thermocouple then the total failure rates for temperature sensing subsystem are as follows: (1) (2) C-2 • λH = 32.85 * 10-9 failures per hour • λL = 5094.16 * 10-9 failures per hour(1) • λDU = 329.29 * 10-9 failures per hour • SFF = 93.96%(2) Assuming the specified failure state is low. Assuming the high and low out of range signals are detected by the logic solver. Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P INSTALLATION No special installation practices are necessary with the Model 3144P in a Safety Instrumented System. However, a full review of the Failure Mode and Security switches is required. Follow the standard installation requirements (see Section 2: Installation). Switches Failure Mode Switch The transmitter monitors itself during normal operation using an automatic diagnostic routine. If the diagnostic routine detects a sensor failure or a failure in the transmitter electronics, the transmitter goes into high or low alarm, depending on the position of the failure mode switch. The analog alarm and saturation values that the transmitter uses depend on whether it is configured to standard (set by the factory) or NAMUR-compliant operation. These values are also custom-configurable in both the factory and the field using the Model 275 HART Communicator. The limits are: • 21.0 ≤I ≤23 for high alarm • 3.5 ≤I ≤3.75 for low alarm The values for standard and NAMUR operation are as follows: Characteristics Standard Operation NAMUR-Compliant Operation Fail High High Saturation Low Saturation Fail Low 21.75 mA ≤I ≤23.0 mA I ≥ 20.5 mA I ≤3.90 mA I ≤3.75 mA 21.0 mA ≤I ≤23.0 mA I ≥ 20.5 mA I ≤3.8 mA I ≤3.6 mA Transmitter Security Switch The transmitter is equipped with a write-protect switch that can be positioned to prevent both accidental and deliberate change of configuration data. Changing Switch Position The Failure Mode and Security switches are located on the top center of the electronics module (see Figure C-1). The electronics module is on the electronics side of the transmitter housing. For transmitters with LCD meters, the electronics module is located behind the LCD meter faceplate. Without a LCD meter 1. If the transmitter is installed, set the loop to manual. 2. Remove the housing cover on the electronics side of the transmitter. Do not remove the transmitter cover in explosive atmospheres when the circuit is live. 3. Set the switches to the desired position (see Figure C-1). 4. Replace the transmitter cover. Both transmitter covers must be fully engaged to meet explosion-proof requirements. 5. Set the loop to automatic control. C-3 Reference Manual 00809-0100-4021, Rev BA April 2003 Model 3144P With a LCD meter 1. If the transmitter is installed, set the loop to manual. 2. Remove the housing cover on the electronics side of the transmitter. Do not remove the transmitter cover in explosive atmospheres when the circuit is live. 3. Remove the housing cover, unscrew the LCD meter screws and gently slide the meter straight off. 4. Set the switches to the desired position (see Figure C-1). 5.
