Re: Solenoid LEDs not on / VEX Base Leak

Sravan.....(I know you are a mentor and not a student...I would never ask to skype w/ a student directly)....Do you have skype? (Please answer only in a PM).

There are problems, and I'd like to help you get them sorted out quickly in real time (as I know your time is very short w/ Tuesday night coming very fast)....They did not teflon tape a number of threaded fittings at the compressor and the pressure relief valve Pic #4 (Fix those firstly, and always back that check valve at the compressor w/ a wrench not allowing it to turn).

That "T" at Tank #2 (right hand tank in the pic), in Pic #1 needs at least a 1" longer pc. of tubing (The tubing between the "T" and tank you cannot even see). Harder to remove from those fittings too! That will leak always!

The 3 potential leaks or more at the compressor (it appears they left out the teflon tape at the following threads.....Compressor Check Valve to "T"...."T" to bell (though I cannot see that too well in pic #4), Bell to Brass Pressure Relief Valve...NOTE: Make sure that no teflon tape gets on the end with the hole or beyond the end of the threads or in the actual bell reducer...That could plug up the hole in the pressure relief valve!

OK, then follow the hose to the first "T" and 1st (left Clippard tank)....Remove and replace that tube w at least / 1" longer tube between tank/T.

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.
