Figure 2-99 Logic diagram of the manual closing procedure
Reclosure via the integrated control functions - on-site control, control via DIGSI, control via serial interface -
can have the same effect as manual closure, see parameter 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 auto-
matically 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 2-100). Each closing operation that is not initi-
ated by the internal automatic reclosure function is interpreted as a manual closure, even it has been initiated
by a control command from the device.
With the user definable logic functions (CFC) further control functions can be processed in the same way as a
manual–close command.
