Can't get pneumatics solenoids to work

[Fej]

Hey guys.

So, my team and I have been trying to get some solenoids working so that we can toggle a couple of pistons on and off. Unfortunately, we haven't been able to get the solenoids to work properly.

We're using, as of right now, one 12v double solenoid, P/N SY3240-5L0U. We have tried several units. We have also tried a single solenoid, P/N SY3140-5FU. They were/are connected to a block P/N SY3000-27-1.

We have gotten none of these to work. The code is working fine. The lights on the cRIO light up, and we can hear the solenoids clicking inside the housings. But the air still takes the same path, no matter what screwholes we put the tubes in nor what pressure we use.

We tested the electrical connections, and the solenoids are getting a little over 12v.

Does anyone have any ideas as to what the problem could be?

Thanks!
