2.1.6 Environmental seal for housing

For NEMA® 4X, IP66, and IP68 requirements, use thread sealing (PTFE) tape
or paste on male threads of conduit to provide a water and dust tight seal.
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.

2.1.7 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 degrees around the transmitter between the housing and
sensor (see Figure 2-12).

Keep the vent path free of any obstruction, such as paint, dust, and
lubrication, by mounting the transmitter so that the process can drain away.

operating on battery backup. Emerson recommends a minimum of 12 Vdc
under normal operating conditions and shielded twisted pair Type A cable.

Procedure

1. To power the transmitter, connect the power leads to the terminals
indicated on the terminal block label.

E. Connect shield back to the power supply ground

Note

The Rosemount 3051 power terminals are polarity insensitive, which
means the electrical polarity of the power leads does not matter
when connecting to the power terminals. If polarity sensitive devices
are connected to the segment, follow terminal polarity. When wiring
to the screw terminals, Emerson recommends using crimped legs.

2. Ensure full contact with 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.

16 Rosemount 3051

January 2020 Quick Start Guide

Note

Emerson does not recommend using a pin or ferrule wire terminal, as
the connection may be more susceptible to loosening over time or
under vibration.

2.4.1 Ground signal wiring

Do not run signal wiring in conduit or open trays with power wiring or near
heavy electrical equipment. Emerson provides grounding terminations on
the outside of the electronics housing and inside the terminal compartment.
Use these grounds when transient protect terminal blocks are installed or to
fulfill local regulations.

Procedure

1. Remove the field terminals housing cover.

2. Connect the wiring pair and ground as indicated in Figure 2-15.
a) Trim the cable shield as short as practical and insulate from

touching the transmitter housing.

Note

Do not ground the cable shield at the transmitter; if the cable
shield touches the transmitter housing, it can create ground
loops and interfere with communications.

b) Continuously connect the cable shields to the power supply

ground.

c) Connect the cable shields for the entire segment to a single

good earth ground at the power supply.

Note

Improper grounding is the most frequent cause of poor
segment communications.

3. Replace the housing cover. Emerson recommends tightening the

cover until there is no gap between the cover and the housing.

4. Plug and seal unused conduit connections.

2.4.2 Power supply

The transmitter requires between 9 and 32 Vdc (9 and 30 Vdc for intrinsic
safety and 9 and 17.5 Vdc for FISCO intrinsic safety) to operate and provide
complete functionality.

Quick Start Guide 17

Quick Start Guide January 2020

2.4.3 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.

2.4.4 Grounding

Signal wiring of the Fieldbus segment cannot be grounded. Grounding out
one of the signal wires will shut down the entire Fieldbus segment.

2.4.5 Shield wire ground

To protect the Fieldbus segment from noise, grounding techniques for
shield wire require a single grounding point for shield wire to avoid creating
a ground loop. Connect the cable shields for the entire segment to a single
good earth ground at the power supply.

2.4.6 Signal termination

For every Fieldbus segment, install a terminator at the beginning and end of
each segment.

2.4.7 Locating devices

Frequently, different personnel install, configure, and commission devices
over time. A Locate Device capability uses the LCD display (when installed)
to assist personnel in finding the desired device.

From the device Overview screen, select the Locate Device button. This
launches a method allowing you to display a Find me message or enter a
custom message to display on the device LCD display.

When you exit the Locate Device method, the device LCD display
automatically returns to normal operation.

Note

Some hosts do not support Locate Device in the DD.

2.6 Trim the transmitter

Emerson calibrates the devices at the factory. Once they are installed,
Emerson recommends performing a zero trim on gage and differential
pressure transmitters to eliminate error due to mounting position or static
pressure effects. You can perform a zero trim using either a Field
Communicator or configuration buttons.

For instructions on trimming the transmitter with AMS Device Manager, see
the Rosemount 3051 HART Revision 5 and 7 Reference Manual.

Note

When performing a zero trim, ensure that the equalization valve is open and
all wet legs are filled to the correct level.

CAUTION

Emerson does not recommend zeroing an absolute transmitter, Rosemount
3051CA or 3051TA models.

Choose your trim procedure.

1. Analog zero trim: Sets the analog output to 4 mA.

• Also referred to as rerange, it sets the lower range value (LRV)

equal to the measured pressure.

• The display and digital HART output remains unchanged.

2. Digital zero trim: Recalibrates the sensor zero.

• The LRV is unaffected. The pressure value will be zero (on display

and HART output). 4 mA point may not be zero.

• This requires that the factory calibrated zero pressure is within a

range of 3% of the URL (0 + 3% x URL).

Example

URV = 250 inH2O

Applied Zero Pressure = +0.03 x 250 inH2O = +7.5 inH2O (compared to
factory settings). The transmitter will reject values outside this range.
