Actual 120 PSI for Storage
The software for pneumatics is pretty sweet - plug everything in, initialize something and away it goes.
The problem is, the cutoff of the automated switch happens anywhere between 110 and 115 PSI. How are teams able to get 120 PSI of storage volume? Is that switch adjustable? (caveat - I haven't done more than a cursory look over pneumatic rules since 2011, which is when the electronics team took over that duty). |

Maybe Q&A adjustment of the pressure switch just to be sure? |
Re: Actual 120 PSI for Storage
The switch can be manually adjusted, however it requires breaking the factory seal around the outside of the switch itself - which has rendered it illegal in the eyes of inspectors in the past. Your mileage may vary.

As far as I know, there's no way to adjust them. |

Re: Actual 120 PSI for Storage
Everyone,
The pressure switch may not be adjusted per R76. The adjustment is to set the position of the microswitch internal to the assembly for operation. It is set at the factory to overcome the differences in microswitch operation from unit to unit. Through testing, the switch is actually a lot more accurate than it appears, as the gauges used on most robots do not have the precision needed to read 120 psi with any repeatability. |

Re: Actual 120 PSI for Storage
We also have the same issue. Ours usually says 112 PSI.

Re: Actual 120 PSI for Storage
Ours only reaches 105 psi.
