General Question About Pneumatics

[itsme]

Umm.. A bit confused
Can I connect the relief valve right after the pressure switch in the circuit (as described in the pneumatics manual). And where do you mean the 2 output ports, on the compressor?
And what do you mean about the calibration? My team spin it a bit because we had air coming out from there (on low pressure, something like 20 PSI).
In the manual the relief valve isn't mentioned in the pneumatics sketches.
So is it or isn't it an obligation to put it in the circuit? (ErichH just mentioned that one output port of the compressor already has a relief valve, and I'm pretty sure my team didn't touch that relief valve).

By the way, the pressure switch is now working perfectly. On 115 PSI the compressor stops its action and starts again when pressure is under 95 PSI.
