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.

A. Housing rotation set screw (5/64-in.)
Procedure
1. Loosen the housing rotation set screw using a 5/64-in. hex wrench.
2. Rotate the housing clockwise to the desired location.
3. If the desired location cannot be achieved due to thread limit, rotate
the housing counterclockwise to the desired location (up to 360°
from thread limit).
4. Retighten the housing rotation set screw to no more than 7 in-lb
when it reaches the desired location.
2.3 Set the switches
Use the following procedure to change the switch configuration:
Set Simulate and Security switch configuration before installation as shown
in Figure 2-14.
•The Simulate switch enables or disables simulated alerts and simulated
AI Block status and values. The default Simulate switch position is
Enabled.
•The Security switch allows (unlocked symbol) or prevents (locked
symbol) any configuration of the transmitter.

2.4 Connect wiring and power up
Use copper wire of sufficient size to ensure that the voltage across the
transmitter power terminals does not drop below 9 Vdc. Power supply
voltage can be variable, especially under abnormal conditions, such as when
January 2020 Quick Start Guide

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.

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.
Quick Start Guide January 2020
16 Rosemount 3051

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.
January 2020 Quick Start Guide
Quick Start Guide 17

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.
2.5 Verifying configuration
Verify the configuration using any HART capable configuration tool or LOI
option code M4.
This section includes configuration instructions for a Field Communicator
and LOI. See Rosemount 3051 Reference Manual for instruction on
configuring with AMS Device Manager.
