, the overcurrent protection always employs the increased
setting values if the automatic reclosing system is ready. The auto-reclosure function provides the signal
79
ready
for controlling the cold load pickup. The signal
79 ready
is always active if the auto-reclosing system
is available, active, unblocked and ready for another cycle. Control via the cold load pickup function is not
ARcycle- related.
Since control via cold load pickup and cyclic control via auto-reclosing system can run simultaneously, the
overcurrent protection must coordinate the input values of the two interfaces. In this context the cyclic auto-
reclosing control has the priority and thus overwrites the release of the cold load pickup function.
If the protective elements are controlled via the automatic reclosure function, changing the control variables
(e.g. by blocking) has no effect on elements that are already running. The elements in question are continued.
