Always

) the 67N-2 elements should be supervised by the status of an internal or ex-

ternal automatic reclosing device. Address

with 79 active

determines that the

67N-2 elements will not operate unless automatic reclosing is not blocked. If not de-
sired, then setting

Always

is selected having the effect that the 67N-2 elements will

always operate, as configured.

The integrated automatic reclosing function of 7SJ62/63/64 also provides the option
to individually determine for each time overcurrent element whether instantaneous
tripping, i.e. normal time delayed tripping unaffected by the automatic reclosing, or
blocking shall take place (see Section 2.14).
