new festo valves
 

anyone know how to hook up the new festo valves with electrical and pneumatics. cant seems to find it.

also it says 24v, will it work on 12v?

im looking for the pdf drawing and instructions for the old and new festo's. you the D shape one and the new longer rectangle one

The 2-port side of the Festo get fittings and are then tubed to either end of the cylinder.
On the 3-port side only the middle port gets a fitting and that's the air-in port from your 60psi regulator.
Each end gets a wire connector and each side gets wired back to pins on the Solenoid bumper (cannot be wired to a Spike relay). You can take the 2-pin connector cables that came in the KOP, cut them in half and use an end for each side of the solenoid.

It needs 24v so the Solenoid bumper must have it's power wired to the Power Distribution Panel's two open 24v connections (for the cRIO power).

Search the Festo site for VUVG-L10-B52-T-M7-1P3

Here's what it looks like with the ports on and wiring.
The blue dots on the top are for manual operation. Push them for a momentary test or push & twist them with a screwdriver to stay on. Make sure you have a working pressure of 1.5-8 bar.:ahh: Okay, okay it needs at least 22 psi to operate.

Im sorry for not understanding this but does this mean that we don't connect the pneumatic solenoid to a 20 amp fuse on the power distribution board?

Re: new festo valves
 

Correct. You supply 24 V to the Solenoid Breakout Board as per:

<R45> All electric power utilized by the ROBOT shall be distributed from the load terminals of the Power Distribution Board. Circuits may not bypass the Power Distribution Board to connect directly to the 120-amp loop.

A. The cRIO-FRC power input must be connected to the 24 Vdc supply terminals on the Power Distribution Board. With the exception of one Solenoid Breakout Board, no other electrical load can be connected to these terminals.

Thanks a lot Ted

go here: http://usfirst.org/roboticsprograms/....aspx?id=10934
and look at robot power distribution diagrams.

there are 12 and 24 vdc variants

Re: new festo valves
 

is there wiring diagrams for both festos?

Re: new festo valves
 

Just to clarify, any debris that gets into the valve body can potentially lock it up internally. If you leave any of the ports unconnected you need to make sure it can't ever get debris in it (dirt, trash, metal files from drilling on the robot, etc). Otherwise, typically you can discharge through some small length of tubing or into a filtered output line so you can have a buffer or a protection against that.

Be careful, the 2009 Festo is 12v and not compatable with the 2010 Festo which is 24v.

By "other" Festo I assume you mean the 2009 KOP Festo?
That is NOT legal for use on the robot this year, because it is commercially available.
2009 Festo Wiring
The 2 wires then go back to a 12v Solenoid Bumper or a Spike (Spike is then controlled by a PWM cable connected to a Digital Sidecar Relay.

The 2010 Festo wiring is just plug in the wired connectors that came with it, then the red and black wires go to a 24v Solenoid Bumper.

Re: new festo valves
 

So are you still allowed to use the 2009 festos?

Re: new festo valves
 

the diagram like last year says that all the analog and pneumatic bumpers go directly to a 20-30 amp on the power distribution board???

Re: new festo valves
 

Grab the latest revision of the Robot Power Distribution Diagram.

The first diagram in that document is the same as last year and is for teams using 12V solenoids.

The second page contains a schematic for teams using 24V solenoids where the solenoid breakout (in the second to last slot on the cRIO) is connected to the 24V supply on the end of the Power Distribution board.

The third page shows how to wire a system to use 2 Solenoid Breakout boards to power both 12V and 24V solenoids on the robot.

Re: new festo valves
 

Im sorry but im not exactly getting this but from what i've been hearing/reading the pneumatic bumper is connected to the 24v source on the distribution board (2 left over leads on the WAGO connector that connects the cRio to the Distribution board) and then the two ends of the solenoid being connected to the bumper right? So if this is right that means were gonna have to use 2010 and only the 2010 festo valves hence the 2008 and 2009 SMC and Festo valves are not going to have the right amount of voltage thus not working right???? This years pneumatics are complicated:mad: we should have sticked with the old SMC and Festo solenoid
thanks for you help

Hey thanks alot I just didn't realize that I could scroll down. Im so sorry but not that i've cleared the air with that it'll be much easier thanks !:D
