Initiation of the automatic reclosing function can be caused by internal protective func-
tions or externally using a binary input. The automatic reclosing system can be pro-
grammed such that any of the elements of Table 2-15 can initiate (Starts 79), not
initiate (No influence), or block reclosing (Stops 79):

With the initiation the automatic reclosure function is informed that a trip command is
output and the appropriate reclosing program is executed.
The binary input messages 2715 „>Start 79 Gnd" and 2716 „>Start 79 Ph"
for starting an automatic reclosure program can also be activated via CFC (fast PLC
task processing). Automatic reclosure can thus be initiated via any messages (e.g.
protective pickup) if address 7164 BINARY INPUT is set to Starts 79.
