2.5 Configuration overview
This section contains information on commissioning and tasks that should be performed on the bench
prior to installation, as well as tasks performed after installation as described in
“Performing transmitter
tests” on page 21 .
Field Communicator, AMS Device Manager, and Local Operator Interface (LOI) instructions are given to
perform configuration functions. For convenience, Field Communicator Fast Key sequences are labeled
“Fast Keys,” and abbreviated LOI menus are provided for each function below.
Full Field Communicator menu trees and Fast Key sequences are available in Appendix C: Field
Communicator Menu Trees and Fast Keys . LOI menu trees are available in Appendix D: Local Operator
Interface.
2.6 Configuration basics
The Rosemount 2051G can be configured either before or after installation. Configuring the transmitter
on the bench using either a Field Communicator, AMS Device Manager, or LOI ensures all transmitter
components are in working order prior to installation. Verify that the security switch is set in the unlock
position (
) in order to proceed with configuration. See Figure 4-2 on page 37 for switch location.
2.6.1 Configuring on the bench
To configure on the bench, required equipment includes a power supply, and a Field Communicator,
AMS Device Manager, or an LOI (option M4). Wire equipment as shown in
Figure 2-4 below. To ensure
successful HART communication, a resistance of at least 250
Ω
s must be present between the
transmitter and the power supply, see “Power supply” on page 40 for details. Connect the Field
Communicator leads to the terminals labeled “COMM” on the terminal block.
