Photo Cells

[Guest]

I have some gate operators which are currently installed which only have connections for 1 set of photo cells on the board, naturally I can add a second set in series but this will mean the gates will stop when the external set of cells is broken, does any body do a bit bit of wizardry that I can add in to make the boards act like a 2 independant photo cell board as there are 6 of these in place.
