HELP!! Pneumatics Problems!

[Geenie]

I'm new to pneumatics programing. I can't figure out why this code is not working. PLEASE HELP! Thank you.

Have you Created the references to the Solenoids yet?

Assuming you have, The values you are using are for a Double Solenoid.
Make sure you that, when you created the references, you set the solenoids to double.
If they are Single Solenoids, Use the On/Off Values.

Also, are you sure you are getting data from your joystick?
Make sure that you look on the Default Dashboard, under the 2 Graphs in the center, there should be some lights that indicate the button presses.

You have an extra copy of the Joystick 2/Buttons SmartDashboard function showing in your picture, but that shouldn't break the pneumatic part of your code.

How are you trying to run it?

Do the green lights on the solenoid module light up in response to the buttons being pressed?

[Geenie]

this is the the Begin VI


The lights that corresponds to the buttons on the solenoid module light up when the buttons are pressed.

If this is true, that means your code is fine and working as it should.
The next suspects are the electrical wiring or the pneumatic plumbing/pressure.

The trouble will be downstream of the solenoid module.
Next check would be if the indicator LED on the solenoid itself is lighting up when you press the buttons.

Potential issues include:

• Is the solenoid breakout power LED on?
• Is the solenoid valve marked as 12v or 24v?
• Is the power wired into the solenoid breakout the matching 12v or 24v required by the solenoid?
• Is the solenoid pneumatic plumbing in the correct ports?
• Is the system pressurized (these piloted solenoids need at least 20 psi to work.

I checked the wiring. So on the module 9472, only lights 1 and 3 light up, but I have in Begin VI(picture on earlier reply) I have solenoid 1,2,3 and 4 called. When I connect the signal cables to the bumper and enable the robot the connection, only one side where the solenoid and the wire signal cables are connected light up. The other side of the solenoid where the signal cable is connected doesn't light up. Also only the cable connected to bumper relay 2 makes the connection light up. When I se all the other relays, the solenoid doesn't light up. Also I'm using the pneumatics bumper, instead of a solenoid breakout, is that the problem?

[Geenie]

I'm using a pnematic bumper instead because our solenoid is 24V and our solenoid breakout is only 6 to 20V, but the bumper LED does light up. And out power wired matches. The system is pressurized, and the ports should be correct.

The way double solenoids work is that one side turns on while the other side simultaneously turns off with only one side of the solenoid should light up at a time.
So for a normal code response you should see the solenoid module LEDs
for button 2 alternate lighting the 0 & 1 LEDs (the first and second LEDs). One is on while the other is off.
So when you start you should probably see just the 1&3 LEDs light up, but when you press and continue to hold buttons 2&3, then you should see the 0&2 LEDs light up while 1&3 go off.

I'm not sure what you are referring to with "pneumatic bumper" vs "solenoid bumper" unless you are just talking about different model years. The breakout you are using has 2-pin connections?
