Bolts are typically carbon steel or stainless steel. 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 Process
Management representative for more information.
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.
Use the following bolt installation procedure:
Procedure
1. Finger tighten the bolts.
2. Torque the bolts to the initial torque value using a crossing pattern.
See Table 1-1 for initial torque value.
3. Torque the bolts to the final torque value using the same crossing
pattern. See Table 1-1 for final torque value.
4. Verify the flange bolts are protruding through the sensor module bolt
holes before applying pressure.

1.5 O-rings
The two styles of Rosemount flange adapters (Rosemount 1151 and
Rosemount 3051/2051/2024/3095) each require a unique O-ring (see Figure
1-3). Use only the O-ring designed for the corresponding flange adapter.
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. When compressed, PTFE O-rings tend to cold
flow, which aids in their sealing capabilities.

Note
You should replace PTFE O-rings if you remove the flange adapter.
1.6 Environmental seal for housing
Thread sealing (PTFE) tape or paste on male threads of conduit is required to
provide a water/dust tight conduit seal 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.
1.7 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
vent path is 360° around the transmitter between the housing and sensor.
(See Figure 1-4.)
Quick Start Guide February 2019
8 Rosemount 2051 Pressure Transmitter and Rosemount 2051CF Series Flowmeter Quick Start Guide

Keep the vent path free of any obstruction, including but not limited to paint,
dust, and lubrication by mounting the transmitter so fluids can drain away.

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.
3. Power terminals are polarity insensitive - connect positive or negative
to either terminal
4. 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.
5. Ensure proper grounding. It is important that the instrument cable
shield:
6. Be trimmed close and insulated from touching the transmitter housing
7. Be connected to the next shield if cable is routed through a junction
box
8. Be connected to a good earth ground at the power supply end
9. Plug and seal unused conduit connections.
10. 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.
11. Replace the housing cover.

4.1.1 Power supply
The dc power supply should provide power with less than two percent ripple.
The transmitter requires between 9 and 32 Vdc at the terminals to operate
and provide complete functionality.
4.1.2 Power conditioner
The DP/PA coupler/link often includes an integrated power conditioner.
4.1.3 Grounding
Transmitters are electrically isolated to 500 Vac rms. Signal wiring can not be
grounded.
4.1.4 Shield wire ground
Shield wire usually requires a single grounding point to avoid creating a
ground loop. The ground point is typically 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 2051 PROFIBUS PA 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 PA control host with either the generic Profile GSD (9700) or
Rosemount 2051 specific GSD (3333) loaded on the host; therefore, it
is not required to change the transmitter identification number at
startup.
5.1.1 Assign address
The Rosemount 2051 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
5.1.2 Configure engineering units
Unless otherwise requested, the Rosemount 2051 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:
