IMPORTANT NOTICE

This installation 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 2051 reference manual (document number

00809-0200-4101) for more instruction. This manual is also available electronically on

www.emersonprocess.com/rosemount.

WARNING

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. Please

review the approvals section of the 2051 reference manual for any restrictions associated

with a safe installation.

• Before connecting a field communicator in an explosive atmosphere, make sure the

instruments in the loop are installed in accordance with intrinsically safe or

non-incendive field wiring practices.

• In an Explosion-Proof/Flame-Proof 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. Only use plugs, adapters, glands or conduit with a compatible thread

form when closing these entries.

C. Bolting Considerations

If the transmitter installation requires assembly of the process flanges, manifolds, or flange

adapters, follow these 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 1 illustrates common transmitter assemblies with the bolt

length required for proper transmitter assembly.

Figure 1. Common Transmitter Assemblies

Bolts are typically carbon steel or stainless steel. Confirm the material by viewing the

markings on the head of the bolt and referencing Figure 2. If bolt material is not shown in

Figure 2, 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 initialtorque value using a crossing pattern. See Figure 2 for initial

torque value.

4. Torque the bolts to the final torque value using the same crossing pattern. See Figure 2

for final torque value.

5. Verify that the flange bolts are protruding through the isolator plate before applying

pressure.

D. O-rings with Flange Adapters

WARNING

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.

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.

E. Inline Gage Transmitter Orientation

The low side pressure port (atmospheric reference) on the inline 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.)

Keep the vent path free of any obstruction, including but not limited to paint, dust, and

lubrication by mounting the transmitter so that the contaminants can drain away.

STEP 2: TAGGING

STEP 3: CONSIDER HOUSING ROTATION

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

Commissioning (Paper) Tag

To identify which device is at a particular location use

the removable tag provided with the transmitter. Ensure

that the physical device tag (PD Tag field) is properly

entered in both places on the removable

commissioning tag and tear off the bottom portion for

each transmitter.

NOTE

The device description loaded in the host system must

be at the same revision as this device. The device

description can be downloaded from

www.emersonprocess.com/rosemount.

1. Loosen the housing rotation set screw.

2. First rotate the housing clockwise to the desired location. If

the desired location cannot be achieved due to thread limit,

rotate the housing counter clockwise to the desired location

(up to 360° from thread limit).

3. Retighten the housing rotation set screw.

STEP 4: CONNECT THE WIRING AND POWER UP

Power Supply

The transmitter requires between 9 and 32 V dc (9 and 15 V dc for FISCO) to operate and

provide complete functionality.

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.

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.

Shield Wire Ground

To protect the fieldbus segment from noise, grounding techniques for shield wire usually

require a single grounding point for shield wire to avoid creating a ground loop. The ground

point is typically at the power supply.

It is important that the instrument cable shield:

• be trimmed close and insulated from touching the transmitter housing

• be connected to the next shield if cable is routed through a junction box

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

Use of ordinary copper wire of sufficient size to

ensure that the voltage across the transmitter

power terminals does not drop below 9 vdc. To

power the transmitter, connect the power leads to

the terminals indicated on the terminal block label.

The power terminals are polarity insensitive, which

means the electrical polarity of the power leads

does not matter when connecting to the power

terminals. When wiring to the screw terminals, the

use of crimped legs is recommended. Tighten the

terminal screws to ensure adequate contact. No

additional power is needed.

STEP 5: VERIFY CONFIGURATION

Each Foundation fieldbus host or configuration tool has a different way of displaying and

performing configurations. Some use Device Descriptions (DD) or DD methods for

configuration and to display data consistently across platforms. There is no requirement that

a host or configuration tool support these features. Use the following block examples to do

basic configuration to the transmitter. For more advanced configurations see the 2051

reference manual (document number 00809-0200-4101).

NOTE

DeltaV users should use DeltaV Explorer for the Resource and Transducer blocks and

Control Studio for the Function Blocks.

To configure the AI Block

AI Block configuration parameters

Use the Pressure, DP Flow, and DP Level examples for guides.
