5.4.3 ANALOG INPUT MINIMUM/MAXIMUM
PATH: ACTUAL VALUES ÖØ A3 LEARNED DATA ÖØ ANALOG IN MIN/MAX
The 489 learns the minimum and maximum values of the analog inputs since they were last cleared. This information can
be cleared using the S1 489 SETUP ÖØ CLEAR DATA ÖØ CLEAR ANALOG I/P MIN/MAX setpoint. When the data is cleared, the
present value of each analog input will be loaded as a starting point for both minimum and maximum. The name of the input
and the units will reflect those programmed for each input. Analog Input minimums and maximums will not update if a digi-
tal input programmed as Test Input is shorted.
If no Analog Inputs are programmed in the
S11 ANALOG I/O setpoints menu, the THIS FEATURE NOT PROGRAMMED flash
message will appear when an attempt is made to enter this group of messages.
