All elements can be blocked individually via binary inputs. In this case pickup and, if possible, direction and
grounded phase will still be reported, however, tripping does not take place since the time elements are
blocked.
To support the commissioning, a message is issued if the current and voltage threshold of an element is
exceeded but the ground fault phasor is not inside of the trip range.
