Maximum Current

 

The maximum current log collects information on events where the unit load

Log Summary

 

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 de-

 

 

fined 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. Press the METERS

 

 

pushbutton on the main menu bar to display the Unit Meter screens. Scroll

 

 

through the meter screens using the up or down arrow pushbuttons on the menu
