Parameter Description Setting range Default Menu path
ExBlo Fc Activate (allow) or inactivate (disallow)
blocking of the module/stage. This
parameter is only effective if a signal is
assigned to the corresponding global
protection parameter. If the signal becomes
true, those modules/stages are blocked that
are parameterized "ExBlo Fc=active".

I< To prevent unintended operation during
faults, this threshold should be used to
distinguish between load current and
overcurrent. A current above this threshold
will be seen as overcurrent and LOP will be
inhibited. If the current detector identifies
load current as overcurrent (threshold to
low), a LOP situation will not be detected
and if the threshold is too high, a fault
situation will be identified as LOP which
results in blocking of protection functions.
