NOTE! If the input type for a loop is set to “skip,” the loop
display will be blank for that loop.
The scanning loop display sequentially displays the infor-
mation for each loop. The data for each loop displays for one
second. To activate the scanning loop display, go to the loop
display, then press and hold the + side of the p key for
three seconds. To exit the scanning mode, press any key.
Alarm Displays
If an alarm condition occurs, the controller displays an
alarm code or alarm message.
Two-Character Alarm Codes
If a process, deviation 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
acknowledged, the alarm code stops blinking. The alarm
code remains on the display until the condition that caused
the alarm is corrected.

pears in the first line of the loop display, as shown in Figure
3.5.
