The number of trips initiated by the 7SJ62 is counted, as long as the position of the
circuit breaker is monitored via breaker auxiliary contacts and binary inputs.
Furthermore, the fault current in each pole of the circuit breaker is determined for each
trip signal. The fault current is indicated in the fault messages and is added to previ-
ously stored fault current values in the statistic-counters to maintain an accumulation
of fault currents, per pole, experienced by the breaker over time.
The operating hours under load are also stored (the current value in at least one phase
is larger than the limit value set under address  %NU&ORVHG , 0,1). The
counter and memory levels are secured against loss of auxiliary voltage.
Setting or resetting of the statistical counters listed above takes place under the menu
item $1181&,$7,21 → 67$7,67,& by overwriting the counter values shown.
