6.4.4 Circuit breaker operation statistics --- address block 56
The number of trip commands initiated by 7SV512,
i.e. the number of breaker fail occurrences, is
counted. Additionally, the interrupted currents are
stated for each individual pole and given under the
fault annunciations (refer Section 6.4.3) following
each trip command. These currents are accumu-
lated and stored. Counter status and stores are se-
cured against auxiliary voltage failure and can be
read off under address 5600. The address can be
reached by direct addressing
DA 5 6 0 0 E
or by
paging with the keys
Ý
or
ß
until address 5600 is
reached. The counters can be called up using the
key
"
for forwards paging or
#
for backwards pag-
ing.
Entry of the codeword is not required for read-off of
counter states.
