5.1 Overview
This section contains information for troubleshooting the Rosemount
™
3051S MultiVariable
™
Transmitter (Rosemount 3051SMV). Diagnostic messages are communicated via the LCD display or a
HART
®
host.
5.2 Device diagnostics
5.2.1 HART host diagnostics
The Rosemount 3051SMV provides numerous diagnostic alerts via a HART host. These alerts can be
viewed in Engineering Assistant 6.3 or later, Field Communicator, or AMS Device Manager.
Table 5-1 on page 108 lists the possible diagnostic alerts that may be shown with the Rosemount
3051SMV. The tables also give a brief description of what each alert indicates and the recommended
actions.
Table 5-2 on page 111 provides summarized maintenance and troubleshooting suggestions for the most
common operating problems. If a malfunction is suspected despite the absence of any diagnostic
messages on the Field Communicator or host, follow the procedures described here to verify that
transmitter hardware and process connections are in good working order.
5.2.2 LCD display diagnostics
In addition to output, the LCD display shows abbreviated operation, error, and warning messages for
troubleshooting. Messages appear according to their priority; normal operating messages appear last.
To determine the cause of a message, use a HART host to further interrogate the transmitter.
A description of each LCD display diagnostic message follows.
Error messages
An error indicator message appears on the LCD display to warn of serious problems affecting the
operation of the transmitter. The LCD display shows an error message until the error condition is
corrected; ERROR appears at the bottom of the display.
