I have pulled the Ladder listing from the GE 90/30 without any other documentation.
Viewing the ladder print out, I see several instances where the same contact is used in series with no vertical wires between.
I have this rung (actually rung 48 in a MANUAL Block)
-]1[------]2[----]3[---]4[----]5[---]4[-----------------------<+>
<+>------]6[----]7[---]8[--------]etc[------------------------------( )
All the contacts are NO, with contact 4, an %I0006 (vacuum sense bellows), used twice in series on this one rung.
Is this for a purpose? Redundancy? Or legacy of some earlier edit?
Inquiring minds....
TIA
