Quick Start Guide
NOTICE
This guide provides basic guidelines for Rosemount 2051 Wireless Transmitters. It does not provide
instructions for configuration, diagnostics, maintenance, service, troubleshooting or intrinsically safe (I.S.)
installations. Refer to the Rosemount 2051 Wireless Reference Manual for more instruction. This manual is
also available electronically on Emerson.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
2051 Wireless 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.
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.
Shipping considerations for wireless products:
The unit was shipped to you without the power module installed. Remove the power module prior to shipping
the unit.
Each power module contains one “D” size primary lithium-thionyl chloride battery. Primary lithium batteries
are regulated in transportation by the U.S. Department of Transportation, and are also covered by IATA
(International Air Transport Association), ICAO (International Civil Aviation Organization), and ARD (European
Ground Transportation of Dangerous Goods). It is the responsibility of the shipper to ensure compliance with
these or any other local requirements. Consult current regulations and requirements before shipping.

1.0 Wireless considerations
1.1 Power up sequence
The power module should not be installed on any wireless device until the
Emerson™Smart Wireless Gateway (Gateway) is installed and functioning
properly. This transmitter uses the green power module (order model number
701PGNKF). Wireless devices should also be powered up in order of proximity
from the Gateway, beginning with the closest. This will result in a simpler and
faster network installation. Enable active advertising on the Gateway to ensure
new devices join the network faster. For more information, see the Emerson
Smart Wireless Gateway Reference Manual.
1.2 Connecting the transmitter with a Field Communicator
In order for the Field Communicator to interface with the Rosemount 2051
Wireless, the power module must be connected. This transmitter uses the green
power module (order model number 701PGNKF). Figure 1 shows how to connect
the Field Communicator to the transmitter. Open the power module
compartment to hook up the leads.

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 a local Emerson representative for more
information.
2.5 Bolt installation
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 the flange bolts are protruding through the isolator plate before
applying pressure.
2.6 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 6 illustrates
common transmitter assemblies with the bolt length required for proper
transmitter assembly.

2.7 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 between the housing and sensor of the transmitter. (See Figure 7.)
Keep the vent path free of any obstruction, including but not limited to paint,
dust, and lubrication by mounting the transmitter so the process can drain away.
Figure 7. In-line Gage Low Side Pressure Port
A. Low side pressure port (atmospheric reference)
3.0 Consider housing rotation
To improve visibility of optional LCD display:
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 8 on page 8).

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

5.0 Trim the transmitter
Devices are calibrated by the factory. Once installed, it is recommended to
perform a zero trim on gage and differential pressure transmitters to eliminate
error due to mounting position or static pressure effects. A zero trim can be
performed using either a Field Communicator or configuration buttons.
For instructions using AMS Wireless Configurator, see the Rosemount 2051
Wireless Reference Manual.
Note
When performing a zero trim, ensure the equalization valve is open and all wet legs are filled
to the correct level.

5.1 Trimming with a Field Communicator
1. Equalize or vent the transmitter and connect Field Communicator.
2. At the menu, input the HART Fast Key sequence.
3. Follow the commands to perform a zero trim.
From the Home screen, enter the Fast Key sequence.
For connecting with a Field Communicator, refer to Figure 1 on page 3.
5.2 Trimming with digital zero trim button
1. Set the transmitter pressure.
2. Remove the electronics housing cover.
3. Press and hold the Zero button for two seconds to perform a digital zero trim.
4. Reinstall transmitter housing cover. Ensure a proper seal by installing the
electronics housing cover so the polymer contacts polymer (i.e. no O-ring
visible).

Note
A zero trim can also be completed using AMS Wireless Configurator once the device has
joined the network.
It is not recommended to zero an absolute transmitter, Rosemount 2051CA or 2051TA models.

Quick Start Guide
6.0 Verify transmitter configuration
Operation can be verified in four locations:
At the device via the Local display (LCD display)
By using the Field Communicator
Via the Smart Wireless Gateway’s integrated web interface
Via AMS Wireless Configurator
6.1 Verify transmitter configuration using LCD display
The LCD display will show the output values at the same rate as the wireless
update rate. Refer to the Rosemount 2051 Wireless Reference Manual for error
codes and other LCD display messages. Press and hold the Diagnostic button for
at least five seconds to display the TAG, Device ID, Network ID, Network Join Status,
and Device Status screens.
6.2 Verify transmitter configuration using Field Communicator
For HART Wireless transmitter communication, a Rosemount 2051 Wireless
Transmitter Device Descriptor is required. For connecting with a Field
Communicator, refer to Figure 1 on page 3.
From the Home screen, enter the Fast Key sequence.
