6.2 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 [
Attn
] in the lower
display.
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.
Push the Advance Key to display [
.9nr
] in the upper display and the message
source (such as [
L.hi
]) in the lower display.
Use the Up and Down keys to scroll through possible responses, such as
Clear
[
CLr
] or Silence [
S.L
]. Then push the Advance or Infinity key to execute the
action.
