Initiation
Initiation of the automatic reclosing function can be caused by internal protection functions or externally via
binary inputs. The automatic reclosing function can be programmed in such manner that any of the elements
of the following Table can initiate (Starts 79), not initiate (No influence), or block reclosing (Stops
79):

On initiation, the automatic reclosure function is informed that a trip command was issued and the respective
reclosing program is now being executed.
The binary input messages 2715
>Start 79 Gnd
and 2716
>Start 79 Ph
for starting an automatic reclo-
sure program can also be activated via CFC (fast PLC task processing). Automatic reclosure can thus be initi-
ated via any messages (e.g. protective pickup) if address 7164 BINARY INPUTis set to Starts 79.
