Reclosure via the integrated control functions - on-site control, control via DIGSI,
control via serial interface - can have the same effect as manual reclosure, see param-
eter 1152 Chapter 2.1.4.1 at margin heading „Circuit Breaker Status“.
If the device has an integrated automatic reclosure, the integrated manual closure
logic of the 7SD610 automatically distinguishes between an external control command
via the binary input and an automatic reclosure by the internal automatic reclosure so
that the binary input „>Manual Close“ can be connected directly to the control
circuit of the close coil of the circuit breaker (Figure 2-95). Each reclosure that is not
initiated by the internal automatic reclosure function is interpreted as a manual reclo-
sure, even it has been initiated by a control command from the device.
With the user definable logic functions (CFC) further control functions can be pro-
cessed in the same way as a manual–close command.
