elements with directional feature! The
device will trip non directional if this
parameter is set to active and no direction
could be determined. Direction detection is
impossible e.g. if the required quantities for
the direction detection cannot be measured
or validated. Direction detection is also
impossible if the frequency deviates
significantly from the nominal frequency.
Caution: If this parameter is set to inactive,
the protective element will trip only if the
direction can be detected.

VX Blo VX Blo = active means that the IG-stage will
only excite if a residual voltage higher than
the pickup value is measured at the same
time. VX Blo = inactive means that the
excitation of the IG stage does not depend
on any residual voltage stage.
