This section contains information for troubleshooting the 3051S ERS System.
Diagnostic messages are communicated via the LCD Display or a HART host.
Procedures and instructions in this section may require special precautions to
ensure the safety of the personnel performing the operation. Information that
raises potential safety issues is indicated with a warning symbol ( ). Refer to
the following safety messages before performing an operation preceded by
this symbol.
The 3051S ERS System provides numerous diagnostic alerts via a HART
host, including a Field Communicator and AMS Device Manager.
Table 5-1 lists the possible diagnostic alerts that may be shown with the
3051S ERS System. The table provides a brief description of each alert and
the recommended actions.
Table 5-2 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 a field
communicator or host, follow the procedures described here to verify that
3051S ERS System and process connections are in good working order.
The optional LCD display on the 3051S ERS System can show 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
3051S ERS System. A description of each LCD diagnostic message follows.
Error Messages
An error indicator message appears on the LCD display to warn of serious
problems affecting the operation of the 3051S ERS System. The error
message is displayed until the error condition is corrected; ERROR appears
at the bottom of the display.
Warning Messages
Warning messages appear on the LCD display to alert the user of
user-repairable problems with the 3051S ERS System, or current operations.
Warning messages appear alternately with other information until the warning
condition is corrected or the 3051S ERS System completes the operation that
triggered the warning message.
