operation signals are summarized by the "OR" logic of Figure 2.23-4. This logic has selection
scheme that is prescribed by scheme switch [FL-Dir]. As a result, the FL can record the current
and voltage data if the fault occurs in either the forward direction or the reverse direction.
Note: For the FL calculation, it is required to fit the direction of the FL calculation
between the FL and other protection function. For example, if Forward is set for
the scheme switch [FL-Dir], user should set Forward for the respective scheme
switches [Z*S-DIR], [Z*G-DIR] and [OC*]. If the contradiction is found in the
direction, the FL does not run. Additionally, it is required to check that the
respective settings of the protection functions are placed properly. For further
information, see section 2.23.3(iii).
