1.5 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 1-10 illustrates common transmitter assemblies with the bolt length
required for proper transmitter assembly.

Bolts are typically carbon steel (CS) or stainless steel (SST). Confirm the
material by viewing the markings on the head of the bolt and referencing
Table 1-1. If bolt material is not shown in Table 1-1, contact a local Emerson
representative for more information.
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 1-1 for initial torque value.
Quick Start Guide February 2019

4. Torque the bolts to the final torque value using the same crossing
pattern. See Table 1-1 for final torque value.
5. Verify the flange bolts are protruding through the isolator plate before
applying pressure.

1.6 O-rings with flange adapters
WARNING
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.

B. O-ring
C. PFTE-based profile (square)
D. Elastomer profile (round)
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.
1.7 Environmental seal for housing
Thread sealing (PFTE) tape or paste on male threads of conduit is required to
provide a water/dust tight conduit seals 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.
1.8 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
Quick Start Guide February 2019

vent path is between the housing and sensor of the transmitter (see Figure
1-12).
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.

2 Consider housing rotation
To improve visibility of optional LCD display:
Procedure
1. Loosen the housing rotation screw.
2. First 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 360° from thread
limit).
3. Re-tighten the housing rotation screw (see Figure 2-1).

3 Set jumpers and switches
3.1 Security
After the transmitter is configured, you may want to protect the configuration
data from unwarranted changes. Each transmitter is equipped with a security
jumper that can be positioned ON to prevent the accidental or deliberate
change of configuration data. The jumper is labeled “Security”. The security
jumper also prevents changes made using the Local Operator Interface.
3.2 Simulate
The simulate jumper is used in conjunction with the analog input (AI) block.
This jumper is used to simulate the pressure measurement and is used as a
lock-out feature for the AI block. to enable the simulate feature, the jumper
must be moved to the “ON” position after power is applied. This feature
prevents the transmitter from being accidentally left in simulate mode.

4 Connect wiring and power up
Use the following steps to wire the transmitter:
Procedure
1. Remove the housing cover on the field terminals side.
2. Connect the power leads to the terminals indicated on the terminal
block label.
•Power terminals are polarity insensitive - connect positive or
negative to either terminal.
3. 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.
Note
The use of a pin or a ferrule wire terminal is not recommended as the
connection may be more susceptible to loosening over time or under
vibration.
4. Ensure proper grounding. It is important that the instrument cable
shield:
•Be trimmed close and insulated from touching the transmitter
housing
•Be connected to the next shield if cable is routed through a
junction box
•Be connected to a good earth ground at the power supply end
5. Plug and seal unused conduit connections.
6. 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.
7. Replace the housing cover.

4.1 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 electronics housing 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.
Procedure
1. Remove the Field Terminals housing cover.
2. Connect the wiring pair and ground as indicated in Figure 4-3. The
cable shield should:
3. Be trimmed close and insulated from touching the transmitter
housing.
4. Continuously connect to the termination point.

6. Replace the housing cover. It is recommended the cover be tightened
until there is no gap between the cover and the housing.
7. Plug and seal unused conduit connections.
4.1.1 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.
4.1.2 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.
4.1.3 Grounding
Signal wiring of the Fieldbus segment cannot be grounded. Grounding out
one of the signal wires will shut down the entire Fieldbus segment.
4.1.4 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.

5 Basic configuration
5.1 Configuration tasks
The transmitter can be configured via either the local operator interface (LOI)
– option code M4, or via a Class 2 Master (DD or DTM™ based). The two basic
configuration tasks for the PROFIBUS PA Pressure transmitter are:
Procedure
1. Assign address.
2. Configure engineering units (scaling).
Note
Rosemount 3051 Profibus Profile 3.02 devices are set to identification
number adaptation mode when shipped from the factory. This mode
allows the transmitter to communicate with any Profibus control host
with either the generic Profile GSD (9700) or Rosemount 3051 specific
GSD (4444) loaded on the host; therefore, it is not required to change
the transmitter identification number at startup.
5.2 Assign address
The Rosemount 3051 Pressure Transmitter is shipped with a temporary
address of 126. This must be changed to a unique value between 0 and 125 in
order to establish communication with the host. Usually, addresses 0–2 are
reserved for masters or couplers, therefore transmitter addresses between 3
and 125 are recommended.
Address can be set via either:
•LOI – see Table 5-1 and Figure 5-1
•Class 2 Master – see Class 2 Master manual for setting address
5.3 Configure engineering units
Unless otherwise requested, the Rosemount 3051 Pressure Transmitter ships
with the following settings:
•Measurement mode: Pressure
•Engineering units: inches H2O
•Scaling: None
Engineering units should be confirmed or configured before installation. Units
can be configured for Pressure, Flow or Level measurement.
Measurement type, Units, Scaling, and Low Flow Cutoff (when applicable) can
be set via either:
