voltage of the switched feeder. This setting does not apply for a close command via the integrated control
functions. If the synchronism check is desired, the device must either feature the integrated synchronism
check function or an external device for synchronism check must be connected.
If the internal synchronism check is to be used, the synchronism check function must be enabled; an addi-
tional voltage U
meterised in the Power System Data 1 (address 210 U4 transformer = Usy2 transf. and the associated
factors).
If no synchronism check is to be performed with manual closing, set MAN. CLOSE = w/o Sync-check. If a
check is desired, set with Sync-check. To not use the MANUAL CLOSE function of the device, set MAN.
CLOSE to NO. This may be reasonable if the close command is output to the circuit breaker without involving
the 7VK61, and the relay itself is not desired to issue a close command.
For commands via the integrated control (on site, DIGSI, serial interface) address 1152 Man.Clos. Imp.
determines whether a close command via the integrated control regarding the MANUAL CLOSE handling for
the protection functions (like instantaneous re-opening when switching onto a fault) is to act like a MANUAL
CLOSE command via binary input. This address also informs the device to which switchgear this applies. You
can select from the switching devices which are available to the integrated control. Select the circuit breaker
which operates for manual closure and, if required, for automatic reclosure (usually Q0). If none is set here, a
CLOSE command via the control will not generate a MANUAL CLOSE impulse for the protection function.

Addresses which have an appended "A" can only be changed with DIGSI, under "Additional Settings".
The table indicates region-specific presettings. Column C (configuration) indicates the corresponding secon-
dary nominal current of the current transformer.
