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".

%(V2/V1)
The %(V2/V1) setting is the unbalance trip pickup
setting. It is defined by the ratio of negative sequence
voltage to positive sequence voltage (%
Unbalance=V2/V1). Phase sequence will be taken into
account automatically.
