3. Report RPM Ranges. All of the data for each selected channel & gage is compared against
this set of ranges & limits. Up to 5 ranges can be selected from the resulting range list which will
look like that in the previous figure, but with the values as set for the “Report RPM Ranges.” The
ranges are set in the Limits Configuration dialog box, discussed in chapter 4. Note that the Range
dependant delay values [set in Limits Configuration (reference chapter 4)] are ignored.
4. > (Greater Than) Report Limits Delay. This selection uses the Report Ranges and Limits.
When “> Report Limits Delay” is selected the report generator only examines the data beyond the
specified delay time, added to the first data record that was detected within a specific RPM range.
For example: If data record number 100 was the first record that was stored when the turbine
RPM was in the range of 85,000 to 100,000 RPM, and data records were being saved at a constant
rate of 1 per second, and the specified delay value of 1.0 minute was given, then the first record
that will be used in the report will be record number 160. All further records acquired in the
85,000 to 100,000 RPM range will also be used in the calculations for Minimum, Average, or
Maximum values compared against the selected Report limit values. Note, however, if the
turbine should slow down enough that a range change is detected, and then speed back up to the
85,000 to 100,000 RPM range, another delay time will be observed before addition records are
added to the previous ones for generating the report.
5. < (Less Than) Report Limits Delay. This selection uses the Report Ranges and Limits.
When “< Report Limits Delay” is selected the report generator only examines the data before the
specified delay time, added to the first data record that was detected within a specific range. Other
than this difference, this option behaves much like the greater than (>) option.
