NOTICE

This 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 HART Revision 5 and 7 Reference Manual for more

instruction. This manual is also available electronically on Emerson.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

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 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.

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.

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 2 on

page 6 illustrates common transmitter assemblies with the bolt length required

for proper transmitter assembly.

Figure 2. Common Transmitter Assemblies

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 or stainless steel. Confirm the material by

viewing the markings on the head of the bolt and referencing Table 2 on page 7.

If bolt material is not shown in Table 2, contact a local Emerson 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 2 for initial torque value.

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

See Table 2 for final torque value.

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

applying pressure.

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.)

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.

Figure 3. In-line Gage Low Side Pressure Port

A. Low side pressure port (atmospheric reference)

Installing high pressure coned and threaded connection

The transmitter comes with an autoclave connection designed for high

pressure applications. Follow the steps below to properly connect the

transmitter to your process:

1. Apply a process-compatible lubricant to the gland nut threads.

2. Slip the gland nut onto the tube, then thread the collar onto the tube end

(the collar is reverse threaded).

3. Apply a small amount of process-compatible lubricant applied to the tube

cone to help prevent galling and facilitate sealing. Insert the tubing into the

connection and tighten finger tight.

4. Tighten the gland nut to a torque of 25 ft-lb.

Note

A weep hole has been designed into the transmitter for safety and leak detection. If fluid

begins to leak from the weep hole, isolate the process pressure, disconnect the

transmitter, and reseal until the leak is resolved.

2.2 Consider housing rotation

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

1. Loosen the housing rotation set screw using a 5/64-in. hex wrench.

2. Turn the housing left or right maximum up to 180° from its original

position.(1)

Note

Over rotating can damage the transmitter.

3. Re-tighten the housing rotation set screw to no more than 7 in-lb when

desired location is reached.

bracket holes.

Quick Start Guide

January 2017

Use the following procedure to change the switch configuration:

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.

Quick Start Guide

Use the following steps to wire the transmitter:

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. Tighten the terminal screws to ensure full contact with the 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.

Note

The use of a pin or ferrule wire terminal is not recommended as the connection may be

more susceptible to loosening over time or under vibration.

4. Ground housing to fulfill local grounding regulations.

5. Ensure proper grounding. It is important that the instrument cable shield be:

a. Trimmed close and insulated from touching the transmitter housing

b. Connected to the next shield if cable is routed through a junction box

c. Connected to a good earth ground at the power supply end

6. If transient protection is needed, refer to section “Grounding for transient

terminal block” on page 11 for grounding instructions.

7. Plug and seal unused conduit connections.

8. Replace the housing cover.

Figure 7. Wiring

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.
