Help for 7VE611 relay needed

Help for 7VE611 relay needed

Help for 7VE611 relay needed

(OP)
For my current project I have to design closing of Circuit Breakers in 1,5 breakers scheme via check synchronizing relay. By reasons out of my responsibility it was chosen that conventional control scheme will be used - control switches, not bay controllers.
It was desided to use 7VE611 check synchronozing relay from Siemens. I see in their User Manual that for 1,5 breaker scheme there is a special voltage circuits connection, which allows to use one relay per diameter. But I cannot find how to implement that connection for activation of SYNC function groups - how to set the relay that when activate for example (via BI) SYNC function 1 relay to compare voltages between inputs Va and Vb, etc. for other groups.
If somebody has solved this problem please give me advice.
I am in contact with local Siemens representatives, but at the moment they are very busy with some urgent matters and cannot spare time for that until next week.  

------------------------
It may be like this in theory and practice, but in real life it is completely different.

Hi lz5pl.
I would like verify your Q, I'll ask our local guys.
One device per diameter, 6 (six) VT inputs ( phase to neutral or phase to phase). Two chanlles per breaker.
3 group of setting and 3 contacts-synch OK ( include LL-DB, etc..).
You need by external binary inputs change group according to breaker and close right contact ( if SC OK).
Are you need check also, that only one binary input is 1 logical in the same time?

Are possible add 3 (three) additional contactors ( voltage and close command) for simlify logic ?

Best Regards.
Slava
