With 7SJ64 and single-phase voltage transformer connection the voltage connected
to voltage input V is always interpreted as the voltage which is to be synchronized.

The configuration of the binary in- and outputs, i.e. the individual adaptation to the
plant conditions, is described in the SIPROTEC 4 System Description. The connec-
tions to the plant are dependent on this actual configuration. The presettings of the
device are listed in Appendix A, Section A.5. Check also whether the labelling corre-
sponds to the allocated annunciation functions.
If binary inputs are used to switch setting groups, please observe the following:
• Two binary inputs must be dedicated to the purpose of changing setting groups
when four groups are to be switched. One binary input must be set for „>Set
Group Bit0", the other input for „>Set Group Bit1". If either of these input
functions is not assigned, then it is considered as not controlled.
• To control two setting groups, one binary input set for „>Set Group Bit0" is suf-
ficient since the binary input „>Set Group Bit1", which is not assigned, is con-
sidered to be not controlled.
• The status of the signals controlling the binary inputs to activate a particular setting
group must remain constant as long as that particular group is to remain active.
The following table shows the allocation of the binary inputs to the setting groups A to
D and a simplified connection diagram for the two binary inputs is illustrated in the fol-
lowing figure. The figure illustrates an example in which both Set Group Bits 0 and 1
are configured to be controlled (actuated) when the associated binary input is ener-
gized (high).
