Types of messages
The display module is capable of storing up to 100 messages. When the message
log is full, the system deletes the oldest message to make room for the most
recent one.
The types of messages include:
• Error Messages—Error messages indicate a problem that may require user
action.
The Fault LED illuminates when you view an error message. It also
illuminates to indicate that an unviewed error message is in the queue and
was followed by other types of messages. When scrolling backward to view
all error messages, the LED illuminates only when an error message is in the
text display window.
• Informational Messages—Informational messages provide feedback on
non-critical changes.
• User Input Messages—User input messages indicate an issue that requires a
choice. The user can choose a selection before the end of a time-out period or
allow the controller to default to a standard choice. User input messages only
occur during system power up.
The Fault LED flashes when a user input message is in the text display
window and requires input. If the user does not provide input within the
time-out period, the message remains, but the LED stops flashing.
A complete list of error messages is available ("Display messages" on page 85 ).
Using the interface
• Scrolling—To view older messages, scroll backward with the Up button
(indicated by the up arrow). To view newer messages, scroll forward with the
Down button (indicated by the down arrow).
The arrival of new messages supersedes the display of any previous
messages. When a new message arrives, the display ignores its previous
scrolling position and presents the new message.
