5.4.4.4 Alarm indication
SCEFRFLO contains an alarm output for the calculated fault distance. If the
calculated fault distance FLT_DISTANCE is between the settings
Low alarm Dis limit
and
High alarm Dis limit
, the ALARM output is activated.
The ALARM output can be utilized, for example, in regions with waterways or other
places where knowledge of certain fault locations is of high importance.
