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 Section 2.1.5.1 Setting Notes at margin
heading “Circuit Breaker Status”.
If the device has an integrated automatic reclosure, the integrated manual closure logic of the 7VK61 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 2-64). Each closing operation that is not initiated
by the internal automatic reclosure function is interpreted as a manual closure, even it has been initiated by a
control command from the device.

If, however, external close commands which should not activate the manual close function are possible (e.g.
external reclosure device), the binary input
>Manual Close
must be triggered by a separate contact of the
control switch (Figure 2-65).
If in the latter case a manual close command can also be given by means of an internal control command from
the device, such a command must be combined with the manual CLOSE function via parameter 1152
Man.Clos. Imp. (Figure 2-63).
