Quick Start Guide
NOTICE
This guide provides basic guidelines for the Rosemount 3051S MultiVariable Transmitter (3051SMV). It also
provides the basic Rosemount 3051SMV configuration guidelines for the Rosemount 3051SFA Reference
Manual, Rosemount 3051SFC Reference Manual, and Rosemount 3051SFP Reference Manual. It does not
provide instructions for diagnostics, maintenance, service, or troubleshooting. Refer to the Rosemount
3051SMV Reference Manual for more instruction. All documents are available electronically at
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
3051SMV Reference Manual for any restrictions associated with a safe installation.
Before connecting a Field Communicator in an explosive atmosphere, ensure the instruments in the loop
are installed in accordance with intrinsically safe or non-incendive field wiring practices.
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.
Install and tighten process connectors before applying pressure.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and 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.

1.5 Bolting considerations
If the transmitter installation requires assembly of a process flange, manifold, or
flange adaptors, follow these assembly guidelines to ensure a tight seal for
optimal performance characteristics of the transmitter. Only use bolts supplied
with the transmitter or sold by Emerson™Process Management as spare parts.
Figure 1 illustrates common transmitter assemblies with the bolt length required
for proper transmitter assembly.

A. Transmitter with coplanar flange
B. Transmitter with coplanar flange and optional flange adaptors
C. Transmitter with traditional flange and optional flange adaptors
D. Transmitter with coplanar flange and optional manifold and flange adaptors
Bolts are typically carbon steel or stainless steel. Confirm the material by viewing
the markings on the head of the bolt and referencing Table 1. If bolt material is
not shown in Table 1, contact the local Emerson Process Management
representative for more information.

Use the following bolt installation procedure:
1. 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.
2. Finger-tighten the bolts.
3. Torque the bolts to the initial torque value using a crossing pattern.
See Table 1 for initial torque value.
4. Torque the bolts to the final torque value using the same crossing pattern.
See Table 1 for final torque value.
5. Verify the flange bolts are protruding through the module isolator plate
before applying pressure.

1.6 O-rings with flange adaptors
2.0 Consider housing rotation
To improve field access to wiring or to better view the optional LCD display:
1. Loosen the housing rotation set screw.
2. Turn the housing up to 180° left or right of its original (as shipped) position.
3. Retighten the housing rotation set screw.
Figure 3. Transmitter Housing Set Screw
A. Feature board
B. Housing rotation set screw (3/32-in.)
Failure to install proper flange adaptor O-rings may cause process leaks, which can result in death or
serious injury. The two flange adaptors are distinguished by unique O-ring grooves. Only use the
O-ring designed for its specific flange adaptor, as shown below:
A. Flange adaptor
B. O-ring
C. PTFE (profile is square)
D. Elastomer (profile is round)
Whenever the flanges or adaptors 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-rings.

Note
Do not rotate the housing more than 180° without first performing a disassembly
procedure. See Section 4 of the Rosemount 3051SMV Reference Manual for more
information. Over-rotation may sever the electrical connection between the sensor module
and the feature board electronics.
3.0 Set the switches
The transmitter’s default configuration sets the alarm condition to high (HI) and
the security to off.
1. If the transmitter is installed, secure the loop and remove power.
2. Remove the housing cover opposite the field terminals side. Do not remove
the housing cover in explosive environments.
3. Slide the security and alarm switches into the preferred position by using a
small screwdriver.
4. Reinstall the housing cover so that metal contacts metal to meet
explosion-proof requirements.

B. Alarm
4.0 Connect wiring and power up
Note
Do not connect the power across the test terminals. Power could damage the test diode in
the test connection. Twisted pairs yield best results. Use 24 AWG to 14 AWG wire and do
not exceed 5,000 feet (1500 meters).
Use the following steps to wire the transmitter:
1. Remove the cover on the field terminals side of the housing.
2. Connect the positive lead to the “PWR/COMM +” terminal, and the negative
lead to the “PWR/COMM –” terminal.
3. If the optional process temperature input is not installed, plug and seal the
unused conduit connection. If the optional process temperature input is being
utilized, see “Install optional process temperature input (Pt 100 RTD sensor)”
on page 9 for more information.

4. If applicable, install wiring with a drip loop. Arrange the drip loop so the
bottom is lower than the conduit connections and the transmitter housing.
5. Reinstall the housing cover and tighten so that metal contacts metal to meet
explosion-proof requirements.
Figure 5 shows the wiring connections necessary to power a Rosemount
3051SMV and enable communications with a hand-held Field Communicator.

A. Power supply
Note
Installation of the transient protection terminal block does not provide transient protection
unless the Rosemount 3051SMV housing is properly grounded.
4.1 Conduit electrical connector wiring (option GE or GM)
For Rosemount 3051SMV with conduit electrical connectors GE or GM, refer to
the cordset manufacturer’s installation instructions for wiring details. For FM
Intrinsically Safe, Division 2 hazardous locations, install in accordance with
Rosemount drawing 03151-1009 to maintain outdoor rating (NEMA®4X and
IP66). See the Rosemount 3051SMV Reference Manual.
NOTICE
When the enclosed pipe plug is utilized in the conduit opening, it must be installed with a minimum
engagement of five threads in order to comply with explosion-proof requirements. Refer to the
Rosemount 3051SMV Reference Manual for more information.

4.2 Power supply
The dc power supply should provide power with less than two percent ripple. The
total resistance load is the sum of the resistance of the signal leads and the load
resistance of the controller, indicator, intrinsic safety barriers, and related
components.
Figure 6. Load Limitation
4.3 Install optional process temperature input
(Pt 100 RTD sensor)
Note
To meet ATEX/IECEx Flameproof certification, only ATEX/IECEx Flameproof cables
(temperature input code C30, C32, C33, or C34) may be used.
1. Mount the Pt 100 RTD sensor in the appropriate location.
Note
Use shielded four-wire cable for the process temperature connection.
2. Connect the RTD cable to the Rosemount 3051SMV by inserting the cable
wires through the unused housing conduit and connect to the four screws on
the transmitter terminal block. An appropriate cable gland should be used to
seal the conduit opening around the cable.
3. Connect the RTD cable shield wire to the ground lug in the housing.
Maximum Loop Resistance = 43.5 ⫻(Power Supply Voltage – 12.0)
HART®communication requires a minimum loop resistance of 250Ω.
