Note
These messages are seen only if the corresponding RTDs are programmed. The actual
messages reflect the RTD Names as programmed.
The 489 will learn the maximum temperature for each RTD. This information can be
cleared using the
S1 489 SETUP ZV CLEAR DATA ZV CLEAR RTD MAXIMUMS setpoint. The
RTD maximums will not update if a digital input programmed as Test Input is shorted. If no
RTDs are programmed in the
S7 RTD TEMPERATURE setpoints page, the THIS FEATURE

flash message will appear when an attempt is made to enter this
group of messages.

PATH: ACTUAL VALUES ZV A3 LEARNED DATA ZV ANALOG INPUT MIN/MAX
Note
These messages are seen only if the corresponding Analog Inputs are programmed. The
actual messages reflect the Analog Input Names as programmed.
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 ZV CLEAR DATA ZV
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 digital input programmed as Test Input is
shorted.
