P05.17
Switch aft. FB alarm Changeover if closing is incomplete
– When this parameter is enabled and the
switching device does not close successfully
(no feedback on presence of opening com-
mand), not only the corresponding feedback
alarm (A03 or A04) is triggered, but changeover
to the secondary line is also controlled.
