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 will be
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.
