4. Responding to a Displayed Message/Error Code
An active message will cause the display to toggle between the normal settings and the
active message in the upper display and [

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 longer exists. If an alarm has silencing enabled, it can
be silenced.
