Responding to a Displayed Message
Attention Codes
An active message will cause the display to toggle be-
tween the normal settings and the active message in
the upper display and Attention [Attn] in the lower
display.
Your response will depend on the message and the
controller settings. Some messages, such as Ramp-
ing and Tuning, indicate that a process is underway.
If the message was generated by a latched alarm or
limit condition, the message can be cleared when the
condition no longer exists by simply pushing the In-
finity ˆ key or alternatively, by following the steps
below. If an alarm has silencing enabled, it can also
be silenced.
Push the Advance Key ‰ to display Ignore [ignr]
in the upper display and the message source, such
as Limit High [Li;h1] in the lower display. Use the
Up ¿ and Down ¯ keys to scroll through possible
responses, such as Clear [`CLr] or Silence [`SiL],
then push the Advance
‰
or Infinity ˆ key to ex-
ecute the action. See the table below for further infor-
mation on the Attention Codes.
Note:
Upon power up, the up-
per or left display will
briefly indicate the firm-
ware revision and the
lower or right display will
