8 LOCAL USER INTERFACE
This category can be used to view event information logged when certain functions are performed by the relay. Information
displayed for each event consists of: Event number and its time of occurrence on the top line; date of occurrence of event
on the second line; detailed event description on the third and fourth lines. The user may use the arrow keys to view the
event information. The user can also enter an event number followed by the [ENT] key to display the information for a spe-
cific event. An error message is displayed if the user enters an invalid event number. Listed below is a list of the possible
event messages available:
