Quick Start Guide
NOTICE
This guide provides basic guidelines for Rosemount 2051 Transmitters. It does not provide instructions for
configuration, diagnostics, maintenance, service, troubleshooting, Explosion-Proof, Flame-Proof, or
intrinsically safe (I.S.) installations. Refer to the Rosemount 2051 Reference Manual for more instruction.
This manual is also available electronically on EmersonProcess.com/Rosemount.
Explosions could result in death or serious injury.
Installation of this transmitter in an explosive environment must be in accordance with the appropriate local,
national, and international standards, codes, and practices. Review the approvals section of the Rosemount
2051 Reference Manual for any restrictions associated with a safe installation.
In an Explosion-proof/Flameproof installation, do not remove the transmitter covers when power is
applied to the unit.
Process leaks may cause harm or result in death.
To avoid process leaks, only use the o-ring designed to seal with the corresponding flange adapter.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and the terminals. High voltage that may be present on leads can cause
electrical shock.
Conduit/cable entries
Unless marked, the conduit/cable entries in the transmitter housing use a 1/2–14 NPT thread form. Entries
marked “M20” are M20 ⫻1.5 thread form. On devices with multiple conduit entries, all entries will have
the same thread form. Only use plugs, adapters, glands, or conduit with a compatible thread form when
closing these entries.
When installing in a hazardous location, use only appropriately listed or Ex certified plugs, adapters, or
glands in cable/conduit entries.

Quick Start Guide
2.4 Bolting considerations
If the transmitter installation requires assembly of the process flanges, manifolds,
or flange adapters, follow the assembly guidelines to ensure a tight seal for
optimal performance characteristics of the transmitters. Use only bolts supplied
with the transmitter or sold by Emerson™as spare parts. Figure 3 on page 6
illustrates common transmitter assemblies with the bolt length required for
proper transmitter assembly.
Figure 3. Common Transmitter Assemblies
A. Transmitter with coplanar flange
B. Transmitter with coplanar flange and optional flange adapters
C. Transmitter with traditional flange and optional flange adapters
D. Transmitter with coplanar flange and optional manifold and flange adapters
Bolts are typically carbon steel or stainless steel. Confirm the material by viewing
the markings on the head of the bolt and referencing Table 2. If bolt material is
not shown in Table 2, contact a local Emerson Process Management
representative for more information.
Carbon steel bolts do not require lubrication and the stainless steel bolts are
coated with a lubricant to ease installation. However, no additional lubricant
should be applied when installing either type of bolt.
Use the following bolt installation procedure:
1. Finger tighten the bolts.
2. Torque the bolts to the initial torque value using a crossing pattern.
See Table 2 for initial torque value.
3. Torque the bolts to the final torque value using the same crossing pattern.
See Table 2 for final torque value.
4. Verify the flange bolts are protruding through the sensor module bolt holes
before applying pressure.

2.5 O-rings with flange adapters
2.6 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, and IP68. 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.
2.7 In-line gage transmitter orientation
The low side pressure port (atmospheric reference) on the in-line gage
transmitter is located in the neck of the transmitter, behind the housing.
The vent path is 360° around the transmitter between the housing and sensor.
(See Figure 4.)
Table 2. Torque Values for the Flange and Flange Adapter Bolts
Bolt material Head markings Initial torque Final torque
Carbon Steel (CS) 300 in-lb 650 in-lb
Stainless Steel (SST) 150 in-lb 300 in-lb
Failure to install proper flange adapter O-rings may cause process leaks, which can result in death or
serious injury. The two flange adapters are distinguished by unique O-ring grooves. Only use the O-ring
that is designed for its specific flange adapter, as shown below:
O-ring location
A. Flange adapter
B. O-ring
C. PTFE based (profile is square)
D. Elastomer (profile is round)
Whenever the flanges or adapters are removed, visually inspect the O-rings. Replace them if there are
any signs of damage, such as nicks or cuts. If you replace the O-rings, re-torque the flange bolts and
alignment screws after installation to compensate for seating of the PTFE O-ring.

Note
The Rosemount 2051 power terminals are polarity insensitive, which means the electrical
polarity of the power leads does not matter when connecting to the power terminals. If
polarity sensitive devices are connected to the segment, terminal polarity should be
followed. When wiring to the screw terminals, the use of crimped legs is recommended.
2. 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. No additional power is needed.
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.
6.1 Signal wiring grounding
Do not run signal wiring in conduit or open trays with power wiring, or near heavy
electrical equipment. Grounding terminations are provided on the outside of the
electronics housing and inside the terminal compartment. These grounds are
used when transient protect terminal blocks are installed or to fulfill local
regulations.
1. Remove the field terminals housing cover.
2. Connect the wiring pair and ground as indicated in Figure 8.
a. Trim the cable shield as short as practical and insulate from touching the
transmitter housing.
Note
Do NOT ground the cable shield at the transmitter; if the cable shield touches the
transmitter housing, it can create ground loops and interfere with communications.
b. Continuously connect the cable shields to the power supply ground.
c. Connect the cable shields for the entire segment to a single good earth
ground at the power supply.
Note
Improper grounding is the most frequent cause of poor segment communications.
3. Replace the housing cover. It is recommended that the cover be tightened
until there is no gap between the cover and the housing.
4. Plug and seal unused conduit connections.
6.2 Power supply
The transmitter requires between 9 and 32 Vdc (9 and 30 Vdc for intrinsic safety,
and 9 and 17.5 Vdc for FISCO intrinsic safety) to operate and provide complete
functionality.

Quick Start Guide
6.3 Power conditioner
A Fieldbus segment requires a power conditioner to isolate the power supply,
filter, and decouple the segment from other segments attached to the same
power supply.
6.4 Grounding
Signal wiring of the Fieldbus segment can not be grounded. Grounding out one of
the signal wires will shut down the entire Fieldbus segment.
6.5 Shield wire ground
To protect the Fieldbus segment from noise, grounding techniques for shield wire
require a single grounding point for shield wire to avoid creating a ground loop.
Connect the cable shields for the entire segment to a single good earth ground at
the power supply.
6.6 Signal termination
For every Fieldbus segment a terminator should be installed at the beginning and
at the end of each segment.
6.7 Locating devices
Devices are frequently installed, configured, and commissioned over time by
different personnel. A “Locate Device” capability has been provided to assist
personnel in finding the desired device.
From the device Overview screen, select the Locate Device button. This will
launch a method allowing the user to display a “Find me” message or enter a
custom message to display on the device LCD display.
When the user exits the “Locate Device” method, the device LCD display
automatically returns to normal operation.
Note
Some hosts do not support “Locate Device” in the DD.

DP Level example
7.6 Display pressure on the LCD display meter
Select the Pressure check box on the display configuration screen.
8.0 Zero trim the transmitter
Note
Transmitters are shipped fully calibrated per request or by the factory default of full scale
(span = upper range limit).
A zero trim is a single-point adjustment used for compensating mounting
position and line pressure effects. When performing a zero trim, ensure the
equalizing valve is open and all wet legs are filled to the correct level.
The transmitter will only allow 3–5% URL zero error to be trimmed. For greater
zero errors, compensate for the offset by using the XD_Scaling, Out_Scaling and
Indirect L_Type which are part of the AI Block.
1. To use guided setup:
a. Navigate to Configure >Guided Setup and select Zero Trim.
b. The method will execute the zero trim.
2. To use manual setup:
a. Navigate to Overview > Calibration > Sensor Trim and select Zero Trim.
b. The method will execute the zero trim.
