Re: Solenoid LEDs not on / VEX Base Leak

For reference (after the original skype call)...Here is the test manifold I asked you to build up using a "T", 1 straight tube fitting, 1 pressure gauge 0~130 PSI or higher, and 1 pressure dump valve....a ball type valve)...Assemble using teflon tape on all threaded fittings.

This is how to assemble our test fitting!

(We will relieve pressure here)Pressure Dump Valve---------"T"----------Straight or 90 degree Hose Fitting (We will connect to the system many times here).
I
I
0~130 PSI Pressure Gauge (We will watch pressure and bleed down or look for leakage here).

Note: It does not matter which ends of the "T" each item is on.

Next: Make sure you can control the compressor on/off via the PDP & robot controls properly. Then we make sure that the compressor threaded fittings are all taped properly, and then we will disconnect from the tanks and install our new test manifold on that first tube.

Turn on and run the compressor up to 120~125 PSI and test the pressure relief valve. Turn off the compressor if it goes beyond 125 PSI before the pressure relief valve starts leaking at the hole in the end (DO NOT ALLOW IT TO EXCEED 130 PSI!)....You can feel leaking by putting a finger over the end where the hole is of the Brass Pressure Relief valve. It should start leaking somewhere between 115 PSI and 125 PSI (Do we need to adjust it?) We will do this action live on skype.

Re: Solenoid LEDs not on / VEX Base Leak

My general philosophy on teflon is you can't have too much on a fitting. I can't see it poking out of any of your connections which would make me say you don't have enough. Wrap it around there 3 or 4 times. I have the same philosophy for tightening the fittings. Tighten em until you can't tighten them anymore. I don't know if this is a good philosophy, but its always worked very well for me. Leaks are very mimimal.

Well. that would be why. We were thinking they were supposed to light up indicating the Solenoid was being powered or it was initialized. I'll test out the buttons and see if that works.

Solenoid lights are working when pressed. Thanks for the clarification Mark.

Now to fix the leak.
