Blocking, if the assigned signal is active
Fig. 43: Principle of the activation and blocking of an example protection stage named »name«.
To block a particular protection stage temporarily by an active signal:
•
There is for each protection stage a setting »ExBlo«, to which a signal can be
•
assigned. This signal can be selected from a list of device-internal and external
signals. (“External signals” are those received from a Digital Input.) The blocking
becomes active when the assigned signal is active.
