IMPORTANT NOTICE

This installation guide provides basic guidelines for Rosemount® Model 3051

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 Model 3051 reference manual (document number

00809-0100-4001) for more instruction. This manual is also available

electronically on www.rosemount.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. Please review the approvals section of the

Model 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/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.

STEP 2: CONSIDER HOUSING ROTATION

STEP 3: SET THE JUMPERS

If alarm and security jumpers are not installed, the transmitter will

operate normally with the default alarm condition alarm high and the

security off.

Housing Rotation

To improve field access or to

better view the optional LCD

meter:

1. Loosen the housing rotation

set screw.

2. Turn the housing left or right up

to 180° from its original

position. Over rotating will

damage the transmitter.

3. Retighten the set screw.

STEP 4: CONNECT THE WIRING AND POWER UP

Use the following steps to wire the transmitter:

1. Remove the housing cover on the side marked FIELD

TERMINALS.

2. Connect the positive lead to the "+" terminal, and the negative lead

to the "–" terminal.

NOTE

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

could damage the test diode in the test connection. Shielded, twisted

pair cable should be used for best results. Use 24 AWG or larger wire

and do not exceed 5,000 feet (1 500 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.

Figure 2 shows wiring connections necessary to power a Model 3051

and enable communications with a hand-held HART communicator.

For low-power transmitters, refer to the reference manual.

Wiring in the Field Transient Wiring

Installation of the transient protection terminal block does not provide

transient protection unless the Model 3051 case is properly grounded.

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 = 43.5 (Power Supply Voltage – 10.5)

A check (⻫) indicates the basic configuration parameters. At minimum,

these parameters should be verified as part of the configuration and

STEP 6: TRIM THE TRANSMITTER

NOTE

Transmitters are shipped from Rosemount Inc. fully calibrated per

request or at the factory default of full scale.

Zero Trim

A zero trim is a single-point adjustment used for compensating

mounting position effects. When performing a zero trim, ensure that

the equalizing valve is open and all wet legs are filled to the correct

level.

If zero offset is less than 3% of true zero, follow the “Using the Model

275 HART Communicator” instructions below. If zero offset is greater

than 3% of true zero, follow the “Using the Transmitter Zero

Adjustment Button” instructions below to rerange.

Using the Model 275 HART Communicator

Using the Transmitter Zero Adjustment Button

Fast Keys Steps

1, 2, 3, 3, 1 1. Vent the transmitter and connect HART communicator.

2. At the menu, input the HART Fast Key sequence.

3. Follow the commands to perform a zero trim.

1. Loosen the certifications label screw and

rotate the label to expose the zero

adjustment buttons.

2. Set the 4 mA point by pressing the zero

button for 2 seconds. Verify that the output

is 4 mA. A meter will display ZERO PASS.
