Safety messages

NOTICE

This guide provides basic guidelines for Rosemount™ 3051S Series Pressure Transmitters. It also
provides the basic electronic 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 3051S
HART Reference Manual for more instruction. This document is also available electronically on

Emerson.com/Rosemount.

WARNING

Explosions could result in death or serious injury.

• Do not remove the transmitter cover in explosive atmospheres when the circuit is live.

• Both transmitter covers must be fully engaged to meet explosion-proof requirements.

• Ensure device is installed in accordance with intrinsically safe or non-incendive field practices.

Process leaks could result in death or serious injury.

• To avoid process leaks, only use the O-ring designed to seal with the corresponding flange

adapter.

Electrical shock could cause death or serious injury.

• Avoid contact with the leads and terminals. High voltage that may be present on leads can cause

electrical shock.

1.5 Bolting considerations

If the transmitter installation requires assembly of a process flange,
manifold, or flange adapters, 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 as spare parts.

Figure 1-4 illustrates common transmitter assemblies with the bolt length

required for proper transmitter assembly.

Note

For all other manifolds, contact Customer Central technical support.

Bolts are typically carbon steel or stainless steel. Confirm the material by
viewing the markings on the head of the bolt and referencing Table 1-1 . If
bolt material is not shown in Table 1-1, contact the local Emerson
representative for more information.

Use the following bolt installation procedure:

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 1-1 for initial torque value.

4. Torque the bolts to the final torque value using the same crossing
pattern. See Table 1-1 for final torque value.

1.6 O-rings with flange adapters

WARNING

Failure to install proper flange adapter O-rings may cause process leaks,
which can result in death or serious injury. Only use the O-ring that is
designed for its specific flange adapter.

A. Flange adapter
B. O-ring
C. PTFE-based profile (square)

D. Elastomer profile (round)

Whenever the flange or adapters are removed, visually inspect the O-rings.
Replace them if there are any signs of damage, such as nicks or cuts. If the O­rings are replaced, re-torque the flange bolts and alignment screws after
installation to compensate for seating of the O-rings.

1.7 In-line gage transmitter orientation

The low side pressure port (atmospheric reference) on the in-line gage
transmitter is located under the sensor module neck label. (See Figure 1-6)

Keep the vent path free of any obstruction, including but not limited to
paint, dust, and lubrication by mounting the transmitter so that any
contaminants can drain away.

2 Tagging

Commissioning (paper) tag

To identify which device is at a particular location, use the removable tag
provided with the transmitter. Ensure the physical device tag (PD Tag field)
is properly entered in both places on the commissioning tag. Tear off the
bottom portion of the tag and write “physical tag” on this portion. This can
now be given to the person who can associate the device ID to the desired
tag.

3 Consider housing rotation

To improve field access to wiring or to better view the optional LCD display:

Procedure

1. Loosen the housing rotation set screw.

2. Turn the housing up to 180° left or right of its original (as shipped)
position.

3. Re-tighten the housing rotation set screw.

Figure 3-1: Transmitter Housing Set Screw

A. LCD display
B. Housing rotation set screw (3/32-in.)

CAUTION

Do not rotate the housing more than 180° without first performing a
disassembly procedure. Over-rotation may sever the electrical
connection between the sensor module and the electronics.

4 Connect wiring and power up

Prerequisites

The transmitter requires 9-32 Vdc to operate. Type A FOUNDATION™ Fieldbus
wiring 18 awg twisted shielded pair is recommended.

Procedure

1. Remove and discard orange conduit plugs.

2. Remove the housing cover labeled “Field Terminals.”

3. Connect the power leads to the terminals indicated on the terminal
block.

Figure 4-1: Transmitter Wiring

A. Minimize distance
B. Trim shield and insulate
C. Ground for transient protection

D. Insulate shield

E. Connect shield back to power supply ground

Note

The device 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, follow terminal polarity. When wiring to
the screw terminals, Emerson recommends using crimped legs.

February 2021 Quick Start Guide

4. CAUTION

When the enclosed threaded plug is utilized in the conduit opening,
it must be installed with a minimum thread engagement in order to
comply with explosion-proof requirements. For straight threads, a
minimum of seven threads must be engaged. For tapered threads, a
minimum of five threads must be engaged.

Plug and seal the unused conduit connection with the provided
conduit plug.

5. 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.

6. Reinstall the housing cover and tighten so the cover is fully seated
with metal to metal contact between the housing and cover in order
to meet explosion proof requirements.

Note

Installation of the transient protection terminal block does not
provide transient protection unless the Rosemount 3051S case is
properly grounded.

4.1 Ground signal wiring

Do not run signal wiring in conduit or open trays with power wiring, or near
heavy electrical equipment. Grounding terminations are provided on the
sensor module and inside the terminal compartment. These grounds are
used when transient protection terminal blocks are installed or to fulfill local
regulations.

Procedure

1. Remove the Field Terminals housing cover.

2. Connect the wiring pair and ground as indicated in Figure 4-1.
The cable shield should:

• Be trimmed close and insulated from touching the transmitter

housing

• Continuously connect to the termination point

• Be connected to a good earth ground at the power supply end

3. Replace the housing cover. It is recommended the cover be
tightened until there is no gap between the cover and the housing.

4. Plug and seal the unused conduit connection with the provided
conduit plug.

4.2 Conduit electrical connector wiring (option GE or GM)

For Rosemount 3051S with conduit electrical connectors GE or GM, refer to
the cordset manufacturer’s installation instructions for wiring details. For FM
Intrinsically Safe, non-incendive or FM FISCO Intrinsically Safe hazardous
locations, install in accordance with Rosemount drawing 03151-1009. See
the Rosemount 3051S Reference Manual.

4.3 Power supply

The transmitter requires between 9 and 32 Vdc to operate and provide
complete functionality.
