Use the Select key as described above and enter the Slot Number from
the Common Slots Screen or Master Slot Number List of the desired
Standard parameter to be trended. The selected parameter description will be
displayed for the Data Point. Setting this Slot Number to zero will disable
trending for that particular Data Point. Any or all points can be disabled.
Only displayed if the Associated Slot Number is not zero. This is the
minimum value displayed for the Y-axis. Selecting a parameter for a Data
Point sets this to the default value, which is the lowest value allowed
for that parameter. It can be changed to a value that provides a more
appropriate resolution for the parameter being monitored. To change,
Standard use the Select key as described above and enter the desired value.
The value must always be set to a value less than the Data Point Max.
Otherwise, a red graph is displayed on the Trend screen with the words
TREND MAX MUST BE > TREND MIN. If the parameter selected for this
data point is a digital type (on/off), this value must be set to zero (0). Zero
indicates the OFF state.
Only displayed if the associated Slot Number is not zero. This is the
maximum value displayed for the Y-axis. Selecting a parameter for a Data
Point sets this to the default value, which is the highest value allowed
for that parameter. It can be changed to a value that provides a more
appropriate resolution for the parameter being monitored. To change,
use the Select key as described above and enter the desired value. The
value must always be set to a value greater than the Data Point Min.
Otherwise, a red graph is displayed on the Trend screen with the words
Standard
TREND MAX MUST BE > TREND MIN.
There are 20 Y-axis divisions. If a min-max span is selected that is not
evenly divided by 20, the program will automatically select the next
higher max value that makes the span evenly divided by 20 (if compressor
application is other than P). For example, if 0.0 is selected as the min and
69.0 is selected as the max, the program will insert 70.0 as the max value.
If the parameter selected for this data point is a digital type (on/off), this
value must be set to one (1). One indicates the on state.
