IMPORTANT NOTICE

This installation guide provides basic guidelines for Rosemount 3051C/T transmitters

(reference manual document number 00809-0100-4051). It does not provide

instructions for diagnostics, maintenance, service, or troubleshooting. This document

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 3051C/T reference manual for any

restrictions associated with a safe installation.

• Before connecting a HART communicator in an explosive atmosphere, ensure 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.

• Install and tighten process connectors before applying pressure.

Electrical shock can result in death or serious injury.

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

leads can cause electrical shock.

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 initial torque 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.

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.

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 process can drain away.

Figure 3. Inline Gage Transmitter

STEP 2: CONSIDER HOUSING ROTATION

STEP 3: SET SWITCHES (OPTION D1)

(

If alarm and security adjustment option is not installed, the transmitter will operate normally

with the default alarm condition alarm high and the security off.

To improve field access to wiring or to better

view the optional LCD display:

1. Loosen the housing rotation set screw.

2. First, using a 5/64-in. hex wrench, 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 180°

from thread limit).

3. Retighten the housing rotation set screw.

STEP 4: CONNECT WIRING AND POWER UP

Connect Wiring and Power Up

Use the following steps to wire the transmitter:

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

2. Connect the positive lead to the “+” terminal, and the negative lead to the “–” terminal.

NOTE

Do not connect the power across the test terminals. Power could damage the test diode in

the test connection. Twisted pairs yield best results; shielded signal wiring is not necessary.

Use 24 AWG or larger wire and do not exceed 5,000 feet (1500 meters).

3. Plug and seal unused conduit connections.

4. 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.

5. Replace the housing cover.

The figures below show the wiring connections necessary to power a 3051C/T and enable

communications with a hand-held HART communicator.

Transmitter Wiring (4-20 mA / HART)

Installation of the transient protection terminal block does not provide transient protection

unless the 3051 case is properly grounded.

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 sensor module and

inside the Terminal Compartment. These grounds are used when transient protect terminal

blocks are installed or to fulfill local regulations. See Step 2 below for more information on

how the cable shield should be grounded.

1. Remove the Field Terminals housing cover.

2. Connect the wiring pair and ground as indicated in Figure 6. The cable shield should:

a. Be trimmed close and insulated from touching the transmitter housing.

b. Continuously connect to the termination point.

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

Figure 6. Wiring

3. Replace the housing cover. It is recommended that the cover be tightened until there is

no gap between the cover and the housing.

4. Plug and seal unused conduit connections.

Power Supply

The dc power supply should provide power with less than two percent ripple. The total

resistance load is the sum of the resistance of the signal leads and the load resistance of

the controller, indicator, and related pieces. Note that the resistance of intrinsic safety

barriers, if used, must be included.

Maximum Loop Resistance =
