Attention
An active message will cause the
display to toggle between the nor-
mal settings and the active mes-
sage instance in the upper display,
[Attn]
in the lower display, and the
Zone will flash reflecting the Zone
which generated the message.
Your response will depend on the
message and the controller settings.
Some messages, such as Ramping
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 lon-
ger exists. If an alarm has silencing
enabled, it can be silenced.
Push the Advance Key
