Pneumatic Problems

[Spiders]

So we have all the pnuematics set up correctly running 60 on the regulater and 115 (?) on the pressure switch before it stops, but the pneumatic wont extend, the double solenoid is connected to the spikes with fwd and rev on each but is not working?? not even the manual buttons work! whats wrong?

[seanl]

did you wire the solenoid by putting the
2 black together which goes into the breaker panel
wiring the 2 red wires with diodes going to the relay?

...? um no lemme try

[Spiders]

so the black go to the 20 amp breaker and the red each have there own spike?

[seanl]

2 blacks go to ground on the breaker panel. and the 2 reds go to the spike with a diode to the m+ and m- on the spike.

[Spiders]

we dont have any diodes, do we have to have them?

[seanl]

im not sure on this but... i think you can have the black and red going to 2 different spikes or.. if you have any extra led u can use those(light emitting DIODE );)

[Spiders]

its like this atm

[Spiders]

nvm it corrupted

[seanl]

i cant really tell anything from that pic

[Spiders]

is the magnetic switch have to be on there also?

[Spiders]

here is another, the red are coming from the dble soliniod

Diodes have not been required on Spikes for several years. You should have the two blacks running to the ground on your circuit breaker, a red to M+, and a red to M-. Of bigger concern here, though, is that your solenoids aren't even switching manually... hopefully someone with more pneumatics expertise than I can offer some insight.

[Spiders]

so the two reds are goin to one spike then?

[Spiders]

dang we are really confused on these lol

[jgannon]

so the two reds are goin to one spike then?
That is how we have wired ours, yes. There are other ways of doing it, but this one definitely works.

[seanl]

yea they both go to one spike and the blacks go to the ground on the breaker panel. thanks jgannon i guess i learned something new today. excuse me for my mistake.

[Spiders]

oh

[seanl]

are you guys going to LA regional?

[Spiders]

:mad: grr there still not working:confused:

[Spiders]

are you guys going to LA regional?

yeh, we are

[Spiders]

maybe there not working cuz the magnetic switches arent plugged in? where do they plug into?

[seanl]

cool come by and say hi well be there and i cant help you with the magnetic switch.

[jgannon]

maybe there not working cuz the magnetic switches arent plugged in? where do they plug into?
The magnetic switches are an optional accessory. If you were using them, they would plug into the RC. However, they are most definitely not required for the solenoids to operate.

[Spiders]

the tubes goin to the pnuematic are A and B while P is coming from the cylinders correct? while ea and eb are sealed?

[seanl]

you don't seal the empty holes those are the vents that might jut be your problem.

[Spiders]

ok.. where gonna open them.. still doesnt work..

[Spiders]

how far do these have to be open?

those look open all the way it should work like that.

yeh, that is what weve been using

[Spiders]

we just switched to our extra soleniod hopefully that other one was defective :P

[Spiders]

well one of the manual buttons work on this one but nothing else

[seanl]

so u have ea ab open
A, B to the piston
p is air in

[Spiders]

FINALLY! we switched out the wires and connected a black and red to the spikes so each spike has a black and red

[Spiders]

thnx for the help! :)

[Spiders]

oh i thought we where going to L.A. one but where going to the SD one, didnt know there was SD one lol
