V-Protection Module – Voltage Protection [ANSI 27/59]
Setting Group Parameters of the Voltage Protection Module
Parameter Description Setting range Default Menu path
Function Permanent activation or
deactivation of
module/stage.

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".
