Rosemount™ 3051G Pressure

Transmitter

with 4-20mA HART® Protocol (Revision 5

and 7)

Note

Before installing the transmitter, confirm the correct device driver is loaded on the host systems. See

System readiness.

NOTICE

This installation guide provides basic guidelines for Rosemount 3051 transmitters. It does not provide

instructions for configuration, diagnostics, maintenance, service, troubleshooting, Explosion-Proof,

Flameproof, or intrinsically safe (I.S.) installations. Refer to the Rosemount 3051 Reference Manual

(document number 00809-0100-5007) for more instruction. This manual is also available

electronically on www.emerson.com.

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. Review the approvals section of the

Rosemount 3051 Reference Manual for any restrictions associated with a safe installation.

Before connecting a HART-based 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/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 otherwise marked, the conduit/cable entries in the housing enclosure use a ½–14 NPT form.

Only use plugs, adapters, glands, or conduit with a compatible thread form when closing these entries.

Physical access

Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end

users’ equipment. This could be intentional or unintentional and needs to be protected against.

Physical security is an important part of any security program and fundamental to protecting your

system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for

all systems used within the facility.

1 System readiness

1.1 Confirm HART revision capability

•If using HART based control or asset management systems, please

confirm the HART capability of those systems prior to transmitter

installation. Not all systems are capable of communicating with HART

Revision 7 protocol. This transmitter can be configured for either HART

Revision 5 or 7.

•For instructions on how to change the HART revision of your transmitter,

see Switch HART revision mode.

1.2 Confirm correct device driver

•Verify the latest device driver (DD/DTM™) is loaded on your systems to

ensure proper communications.

•Download the latest device driver at Emerson.com or FieldComm Group

1.2.1 Rosemount 3051 device revisions and drivers

2 Transmitter installation

2.1 Step 1: Mount the transmitter

2.1.1 Liquid applications

Procedure

1. Place taps to the side of the line.

2. Mount beside or below the taps.

3. Mount the transmitter so that the drain/vent valves are oriented

upward.

Figure 2-1: In-Line Liquid Applications

2.1.2 Gas applications

Procedure

1. Place taps in the top or side of the line.

2. Mount beside or above the taps.

2.2 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 2-5).

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

paint, dust, and lubrication by mounting the transmitter so that the process

can drain away.

2.3 Step 2: Set the switches

Set Alarm and Security switch configuration before installation as shown in

Figure 2-6.

•The Alarm switch sets the analog output alarm to high or low.

—Default alarm is high.

•The Security switch allows (unlocked symbol) or prevents (locked

symbol) any configuration of the transmitter.

—Default security is off (unlocked symbol).

Use the following procedure to change the switch configuration:

Procedure

1. If the transmitter is installed, secure the loop, and remove power.

2. Remove the housing cover opposite the field terminal side. Do not

remove the instrument cover in explosive atmospheres when the

circuit is live.

3. Slide the security and alarm switches into the preferred position

using a small screwdriver.

4. Reattach the transmitter cover. The cover must be fully engaged to

comply with explosion-proof requirements.

BRL ≥ 250

CCurrent meter (optional)

Shielded twisted pair cable should be used for best results. Use 24 AWG or

larger wire that does not exceed 5,000 feet (1500 meters) in length. 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.

CAUTION

Installation of the transient protection terminal block does not provide

transient protection unless the Rosemount 3051 case is properly grounded.

Do not run signal wiring in conduit or open trays with power wiring, or near

heavy electrical equipment.

Do not connect the powered signal wiring to the test terminals. Power could

damage the test diode in the terminal block.

Use the following steps to wire the transmitter:

Procedure

1. Remove the housing cover on the FIELD TERMINALS side.

2. Connect the positive lead to the “+” terminal (PWR/COMM) and the

negative lead to the “–” terminal.

3. Ground housing to fulfill local grounding regulations.

4. Ensure proper grounding. It is important that the instrument cable

shield be:
