Solenoid is teh fail

[Joe Finkel]

Mark, when you mention the SMC SY3000 solenoid,you probably also meant
that it has to be 24v as well?

Hi Joe,

It doesn't have to be, but you do probably want to chose all 12v solenoids or all 24v solenoids if you can afford what you need to buy.
If a team has really tight $, then there are a lot of combinations of 12v & 24v solenoids that are possible this year.

One Solenoid Bumper can only support one or the other voltage.
We are allowed two Solenoid Bumpers though, and one could be 12v while the other could be 24v. In addition, 12v solenoids can be driven through the Digital Sidecar Relay outputs w/Spike.

This test bothers me, because the 2009 Festo was wired differently than earlier years. The results you saw could easily mean the 2009 Festo wiring was on pins 1&2 rather than 1&3, or vice-versa.

A guy I work with was telling me about one of the supervisors he had many years back. He quoted him as saying - "Gene, don't give me this bull about how you're absolutely sure. You're a goddang engineer, leave yourself some wiggle room. From now on when I ask you your name, you'd better say 'I'm 95% sure it's Gene.'"

Double-Triple check everything again, have an outside person look at it, and when you're 95% sure that its all correct and it still doesn't work, try replacing it.

Chances are if the replacement doesn't work, you shouldn't have been 95% sure.
Best of luck.

I just have a nagging feeling the vent port has a plug in it. I'd love to see a close-up, non-blurry photo of the valve plumbing.
