Quick Start Guide
NOTICE
This guide provides basic guidelines for Rosemount 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 Rosemount 3051 Reference Manual for more instruction.
This manual is also available electronically EmersonProcess.com/Rosemount.
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. Review the approvals section of the Rosemount
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.
To avoid process leaks, only use the o-ring designed to seal with the corresponding flange adapter.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and the terminals. High voltage that may be present on leads can cause
electrical shock.
Conduit/cable entries
Unless marked, the conduit/cable entries in the transmitter housing use a 1/2–14 NPT thread form. Entries
marked “M20” are M20 ⫻1.5 thread form. On devices with multiple conduit entries, all entries will have
the same thread form. Only use plugs, adapters, glands, or conduit with a compatible thread form when
closing these entries.
When installing in a hazardous location, use only appropriately listed or Ex certified plugs, adapters, or
glands in cable/conduit entries.

1.4 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 2 illustrates
common transmitter assemblies with the bolt length required for proper
transmitter assembly.
Figure 2. Common Transmitter Assemblies
A. Transmitter with coplanar flange
B. Transmitter with coplanar flange and optional flange adapters
C. Transmitter with traditional flange and optional flange adapters
D. Transmitter with coplanar flange and optional manifold and flange adapters
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. If bolt material is
not shown in Table 1, contact the local Emerson Process Management
representative for more information.
Use the following bolt installation 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 for initial torque value.
4. Torque the bolts to the final torque value using the same crossing pattern.
See Table 1 for final torque value.
5. Verify that the flange bolts are protruding through the isolator plate before
applying pressure.

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:
A. Flange adaptor
B. O-ring
C. PTFE based (profile is square)
D. Elastomer (profile is 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-rings.

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 3.)
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.
Figure 3. In-line Gage Low Side Pressure Port
A. Low side pressure port (atmospheric reference)
2.0 Consider housing rotation
To improve field access to wiring or to better view the optional LCD display:
1. Loosen the housing rotation set 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. Retighten the housing rotation set screw.

6.0 Trim the transmitter
Note
Transmitters are shipped fully calibrated per request or by the factory default of full scale
(span = upper range limit).
6.1 Zero trim
A zero trim is a single-point adjustment used for compensating mounting
position effects. When performing a zero trim, ensure the equalizing valve is open
and all wet legs are filled to the correct level.
There are two methods to compensate for mounting effects:
Field Communicator
Transmitter zero adjustment buttons
Select the appropriate method and follow instructions below:
Using the Field Communicator
If zero offset is within 3% of URL, follow the Using the Field Communicator
instructions below. This zero trim will affect the 4–20 mA value, the HART PV, and
the display value.
1. Equalize or vent the transmitter and connect Field Communicator.
2. At the menu, input the HART Fast Key sequence (refer to Table 2 or Table 3).
3. Follow the commands to perform a zero trim.
Using the transmitter zero adjustment buttons
Using the transmitter zero adjustment buttons, the lower range value (LRV) will
be set to the pressure applied to the transmitter. This adjustment will affect the
4–20 mA value only. Perform the following steps to perform a rerange using the
zero adjustment buttons.

7.0 Safety Instrumented Systems (SIS)
The following section applies to Rosemount 3051C Transmitters used in SIS
applications.
7.1 Installation
No special installation is required in addition to the standard installation practices
outlined in this document. Always ensure a proper seal by installing the
electronics housing cover(s) so that metal contacts metal.
The loop must be designed so the terminal voltage does not drop below 10.5 Vdc
when the transmitter output is 22.5 mA.
Position the security switch to the ON position to prevent accidental or deliberate
change of configuration data during normal operation.
7.2 Configuration
Use any HART-compliant master to communicate with and verify configuration of
the Rosemount 3051.
User-selected damping will affect the transmitters ability to respond to changes
in the applied process. The damping value + response time must not exceed the
loop requirements.
Note
1. Transmitter output is not safety-rated during the following: configuration changes,
multidrop, loop test. Alternative means should be used to ensure process safety during
transmitter configuration and maintenance activities.
2. DCS or safety logic solver must be configured to match transmitter configuration.
Figure 13 identifies the two alarm levels available and their operation values. Position
the alarm switch to the required HI or LO alarm position.
