9.2.6 Maximum Current Log

Press the METERS pushbutton on the main menu bar to display the Unit Meter screens.
Scroll through the meter screens using the
Maximum Current Log Summary screen is displayed.
The maximum current log collects information on events where the unit load exceeds a
user-defined current limit within a user-defined time interval. The user can choose a time
period up to 9999 minutes and a load limit up to 100%. The user can also select whether
the limit defined is a three-phase average of the individual phase currents or is a limit
defined for each phase individually. In the first case an event is logged if the average across
the phases exceeds the defined limit within a given time period and in the second case an
event is logged if any individual phase exceeds the defined limit within a given time period.
The Maximum Current Log Summary screen displays the number of times the limit has
been exceeded, the date of the last log reset, the maximum percent of full load, and the
total time over the limit. It also displays the average percent load over the limit. This
measurement differs, depending on whether a three-phase average or an individual phase
measurement is selected. Figure 9-21 shows the Maximum Current Log Summary screen.
