1 About this guide

This guide provides basic guidelines for Rosemount 2051 Pressure
Transmitters. It does not provide instructions for configuration, diagnostics,
maintenance, service, troubleshooting, Explosion-proof, Flameproof, or
intrinsically safe (I.S.) installations. Refer to Rosemount 2051 Reference

Manual for more instructions. This guide is also available electronically at
Emerson.com/Rosemount.

1.1 Safety messages

WARNING

Explosions could result in death or serious injury.

Installation of these transmitters 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 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.

Conduit/cable entries

Unless marked, the conduit/cable entries in the transmitter housing use a
½–14 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.

3.4 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 3-2 illustrates common transmitter assemblies with the bolt length

required for proper transmitter assembly.

10

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 (CS) or stainless steel (SST). Confirm the
material by viewing the markings on the head of the bolt and referencing

Table 3-1. If bolt material is not shown in Table 3-1, contact a local Emerson

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:

Procedure

1. Tighten the bolts by hand.

2. Torque the bolts to the initial torque value using a crossing pattern.
See Table 3-1 for initial torque value.

3.5 O-rings

The two styles of Rosemount flange adapters (Rosemount
3051/2051/2024/3095) each require a unique O-ring (see Figure 3-3). Use
only the O-ring designed for the corresponding flange adapter.

WARNING

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. When compressed, PTFE O­rings tend to cold flow, which aids in their sealing capabilities.

Quick Start Guide 11

B. O-ring
C. PFTE based

D. Elastomer

Note

You should replace PTFE O-rings if you remove the flange adapter.

3.6 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.

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 3-4.)

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

7 Wire, ground, and power up

Use of copper wire of sufficient size to ensure that the voltage across the
transmitter power terminals does not drop below 9 Vdc. Power supply
voltage can be variable, especially under abnormal conditions such as when
operating on battery backup. A minimum of 12 Vdc under normal operating
conditions is recommended. Shielded twisted pair Type A cable is
recommended.

Procedure

1. To power the transmitter, connect the power leads to the terminals
indicated on the terminal block label.

18

March 2020 Quick Start Guide

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.

7.1 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.

Procedure

1. Remove the field terminals housing cover.

2. Connect the wiring pair and ground as indicated in Figure 7-1.

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.

3. Continuously connect the cable shields to the power supply ground.

a) 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.

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

Quick Start Guide 19

Quick Start Guide March 2020

5. Plug and seal unused conduit connections.

7.2 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.

7.3 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.

7.4 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.

7.5 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.

7.6 Signal termination

For every Fieldbus segment a terminator should be installed at the beginning
and at the end of each segment.
