Environmental seal for housing Thread sealing (PTFE) tape or paste on male threads of conduit is required to provide a water/dust tight conduit seal and meets requirements of NEMA® Type 4X, IP66, IP68, and IP69K. Consult factory if other Ingress Protection ratings are required. For M20 threads, install conduit plugs to full thread engagement or until mechanical resistance is met. Note IP69K rating only available on units with a SST housing and option code V9 in the model string. Note For aluminum housings ordered with M20 conduit entries, transmitters shipped will have 1/2 NPT threads machined into the housing and a 1/2 NPT to M20 thread adapter will be provided. Considerations for environmental sealing listed above should be taken into account when installing the thread adapter. In-line gage transmitter orientation The low side pressure port (atmospheric reference) on the in-line gage transmitter is located on the neck of the transmitter via a protected gage vent (See Figure 1). Keep the vent path free from obstructions including but not limited to paint, dust, and viscous fluids by mounting the transmitter so the process can drain away. Recommended installations have a conduit entry facing the ground so the gage vent is pointing parallel to the ground. Figure 1. In-line Protected Gage Vent Low Side Pressure Port A.

7 March 2018 Use the following steps to wire the transmitter: 1. Remove the housing cover on the FIELD TERMINALS side. 2. Connect the positive lead to the “+” terminal (PWR/COMM) and the negative lead to the “–” terminal. 3. Ensure full contact with Terminal Block screw and washer. When using a direct wiring method, wrap wire clockwise to ensure it is in place when tightening the terminal block screw. Note The use of a pin or a ferrule wire terminal is not recommended as the connection may be more susceptible to loosening over time or under vibration 4. Ground housing to fulfill local grounding regulations. 5. Ensure proper grounding. It is important the instrument cable shield be:  Trimmed close and insulated from touching the transmitter housing  Connected to the next shield if cable is routed through a junction box  Connected to a good earth ground at the power supply end 6. If transient protection is needed, refer to section “Grounding for transient terminal block ” for grounding instructions. 7. Plug and seal unused conduit connections. 8. Reattach the transmitter covers. It is recommended that the cover be tightened until there is no gap between the cover and the housing. The covers must only be capable of being released or removed with the aid of a tool to comply with applicable ordinary locations requirements.  Installation of the transient protection terminal block does not provide transient protection unless the Rosemount 2051HT case is properly grounded.  Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical equipment.  Do not connect the powered signal wiring to the test terminals. Power could damage the test diode in the terminal block.

Figure 4. Wiring Grounding for transient terminal block Ground termination is provided on the outside of the electronics housing and inside the terminal compartment. These grounds are used when the transient protection terminal blocks are installed. It is recommended that 18 AWG or larger wire is used to connect housing ground to earth ground (internal or external). If the transmitter is currently not wired for power up and communication, follow Connect the wiring and power up , step 1 through 8. When the transmitter is properly wired, refer to Figure 4 for internal and external transient grounding locations. Note The Rosemount 2051HT polished 316 SST housing only provides ground termination inside the terminal compartment. 2.4 Verify configuration Verify the configuration using any HART capable configuration tool or Local Operator Interface (LOI) - option code M4. Configuration instructions for a Field Communicator and LOI are included in this step.

11 March 2018 Switch HART Revision mode If the HART configuration tool is not capable of communicating with HART Revision 7, the Rosemount 2051 will load a generic menu with limited capability. The following procedures will switch the HART Revision mode from the generic menu: 1. Manual Setup > Device Information > Identification > Message a.To change to HART Revision 5, Enter: HART5 in the Message field. b.To change to HART Revision 7, Enter: HART7 in the Message field. Note See Table 2 on page 9 to change HART Revision when the correct device driver is loaded. 2.5 Trim the transmitter Devices are calibrated by the factory. Once installed, it is recommended to perform a zero trim on gage transmitters to eliminate error due to mounting position or static pressure effects. A zero trim can be performed using either a Field Communicator or configuration buttons. Note When performing a zero trim, ensure the equalization valve is open and all wet legs are filled to the correct level. 1. Choose your trim procedure. a. Analog zero trim – Sets the analog output to 4 mA. b. Also referred to as a “rerange,” it sets the lower range value (LRV) equal to the measured pressure. c. The display and digital HART output remains unchanged. d. Digital zero trim – Recalibrates the sensor zero. e. The LRV is unaffected. The pressure value will be zero (on display and HART output). 4 mA point may not be at zero. f. This requires the factory calibrated zero pressure is within a range of 3% of the URV [0 ± 3% x URV]. Example URV = 250 inH2O Applied Zero Pressure = ± 0.03x 250 inH2O = ± 7.5 inH2O (compared to factory settings) values outside this range will be rejected by the transmitter Trimming with a Field Communicator 1. Connect the Field Communicator, see “Connect the wiring and power up” on page 6 for instructions. It is not recommended to zero an absolute transmitter, Rosemount 2051HTA model.

2. Follow the HART menu to perform the desired zero trim. Trimming with configuration buttons A zero trim is to be performed using one of the three possible sets of configuration buttons located above the terminal block or under the top tag. To access the configuration buttons on a polished stainless steel housing, remove the terminal side housing cover. To access the configuration buttons on an aluminum housing, loosen the screw on the top tag and slide the tag on the top of the transmitter. Figure 6.
