New trip indication timer
The new trip indication timer can be configured to allow a second trip indication on
the LCD. When several protection stages trip, the first trip indication is displayed
until the time, as specified by the NEW TRIP IND. setting value, has expired. After
this, a new trip indication can displace the old one. The basic protection functions
are not affected by the NEW TRIP IND. setting.
