Alarm Displays
If an alarm condition occurs, the controller displays an alarm
code or alarm message.
Two-Character Alarm Codes
If a process, deviation, ambient warning or failed sensor alarm
occurs, a two-character alarm code appears in the lower left
corner of the loop display.
The alarm code blinks and you cannot change the display until
the alarm has been acknowledged. After the alarm is acknowl-
edged, the alarm code stops blinking. The alarm code remains
on the display until the condition that caused the alarm is cor-
rected.
