thats a rough picture because i can't see the circuit lands.
I'm assuming that jumpers at 1,3,6 is 100 volts
In that case i think that jumpers at 2,4,6 would be 120 volts
and jumpers at 2 and 5 would be 240 volts
or jumpers at 3 and 5 would be 220 volts
You can verify this by removing jumpers at 1,3,6 and installing at 2 and 5
Then measure with ohmmeter that purple and grey are 0 ohms
and that blue is 0 ohms to one side of the ac line.
with all jumpers removed there should be 0 ohms between the tops of
jumpers 1,2,3,4 and are tied to common.
