Manual Close Indication of a Circuit Breaker
SIPROTEC, 7UT6x, Manual
C53000-G1176-C230-2, Release date 06.2012
Functions
2.1 General
If a protection function is to make use of an external manual-close command indicated via a binary input, you
must have selected that logical input indication during the configuration of the binary inputs that corresponds
to the side or measuring location to which the protection function is assigned. From the internal control, the
device uses the same switching objects that were selected at the addresses 831 to 840.
Example:
Command Duration
If you have assigned the time overcurrent protection for phase currents to measuring location M4 and want it
to receive the manual-close command from circuit breaker CB2, you connect the Close command for breaker
CB2 to a binary input and allocate that input to „>ManualClose M4“ (No 30354).
The minimum trip command duration 851 is set in address TMin TRIP CMD. This duration is valid for all
protection functions which can issue a trip command. This parameter can only be altered in DIGSI at Display
Additional Settings.
2.1.4.5 Settings
Addresses which have an appended "A" can only be changed with DIGSI, under Additional Settings.
