2.1 Overview
This section contains information on commissioning and tasks that should be performed on the bench
prior to installation.
Field Communicator and AMS Device Manager instructions are given to perform configuration
functions. For convenience, Field Communicator Fast Key sequences are labeled “Fast Keys” for each
software function below the appropriate headings.
2.2 Safety messages
Procedures and instructions in this section may require special precautions to ensure the safety of the
personnel performing the operations. Information that raises potential safety issues is indicated by a
warning symbol ( ). Refer to the following safety messages before performing an operation preceded
by this symbol.

2.3 Commissioning
Commissioning consists of testing the transmitter and verifying transmitter configuration data. The
Rosemount™3051 Pressure Transmitters can be commissioned either before or after installation.
Commissioning the transmitter on the bench before installation using a Field Communicator or AMS
Device Manager ensures that all transmitter components are in working order.
To commission on the bench, required equipment includes a power supply, a milliamp meter, and a Field
Communicator or AMS Device Manager. Wire equipment as shown in Figure 2-1 and Figure 2-2. To
ensure successful communication, a resistance of at least
250 ohms must be present between the Field Communicator loop connection and the power supply.
Connect the Field Communicator leads to the terminals labeled “COMM” on the terminal block.
Set all transmitter hardware adjustments during commissioning to avoid exposing the transmitter
electronics to the plant environment after installation.
When using a Field Communicator, any configuration changes made must be sent to the transmitter by
using the Send key. AMS Device Manager configuration changes are implemented when the Apply
button is clicked.
2.3.1 Setting the loop to manual
Whenever sending or requesting data that would disrupt the loop or change the output of the
transmitter, set the process application loop to manual. The Field Communicator or AMS Device
Manager will prompt you to set the loop to manual when necessary. Acknowledging this prompt does
not set the loop to manual. The prompt is only a reminder; set the loop to manual as a
separate operation.
2.3.2 Wiring diagrams
Connect the equipment as shown in Figure 2-1 for 4–20 mA HART®or Figure 2-2 for 1-5 Vdc HART Low
Power. To ensure successful communication, a resistance of at least 250 ohms must be present between
the Field Communicator loop connection and the power supply. The Field Communicator or AMS Device
Manager may be connected at “COMM” on the transmitter terminal block or across the load resistor.
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 this
manual for any restrictions associated with a safe installation.
Before connecting a Field Communicator in an explosive atmosphere, ensure the instruments in the
loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.
In an explosion-proof/flameproof installation, do not remove the transmitter covers when power is
applied to the unit.
Process leaks may cause harm or result in death.
Install and tighten process connectors before applying pressure.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause
electrical shock.

Configuration
Connecting across the “TEST” terminals will prevent successful communication for 4–20 mA HART
output.
Turn on the Field Communicator by pressing the ON/OFF key or log into AMS Device Manager. The Field
Communicator or AMS Device Manager will search for a HART-compatible device and indicate when the
connection is made. If the Field Communicator or AMS Device Manager fail to connect, it indicates that
no device was found. If this occurs, refer to Section 5: Troubleshooting.
