SECTION 5 - TROUBLESHOOTING
INTRODUCTION
This section contains all of the possible error messages that can dis-
play on the STT04 terminal.
The troubleshooting tables have four columns:
•
The Message column lists the errors (alphabetically) exactly as
they appear on the terminal.
•
The Affected Device column lists the device type the error can
affect. Some probable cause and corrective action may vary
depending on the affected device.
•
The Probable Cause column provides a brief explanation of the
cause of the error.
•
The Corrective Action column lists corrective actions to take for
each error.
ERROR MESSAGES
When the Status key is pressed, if a problem exits an error message
is displayed. The errors are based on an internal priority structure
where the most critical error takes priority over less critical errors.
ABB digital FSK devices only show one error message at a time. If
more than one error message is present, the one holding the highest
priority must be corrected before other lower priority messages can
be viewed. HART device error messages only occupy one line on the
LCD, therefore more than one error message can be viewed at one
time. Table
5-1 lists the HART error messages in alphabetical order.
Table 5-2 lists ABB FSK device specific and common STT error mes-
sages in alphabetical order.
NOTE: The most common cause of field problems occur due to wir-
ing errors or DCS system configuration errors. Check these areas
first before proceeding.
