C3PO -
There is some miscommunication occurring here. My understanding of your situation follows. If it is incorrect, ignore the rest of the post:
You have more than 8 solenoids that are 24V, but you only need to activate up to 2 at any one time.
This is do-able from an engineering point of view. The 24V supply can most certainly power 2 valves at once, and it doesn't matter how many valves you aren't using. Great. However, the rules prevent this. Since the penalty of trying to power >8 valves at once is that your robot reboots and you likely lose the match, the rules are written conservatively. I strongly agree with (and proposed) this conservatism.
In post #5, you spoke with respect to tech, but Don responded to you with respect to rules. You interpreted Don's response as if he was also talking tech, which resulted in the confusion.
Long story short, use up to 8 24V solenoids. All other solenoids will have to be 12V. If you wish, request a change for 2011.
