"Overfilling" the accumulators accomplishes nothing except stressing the compressor/breaker and wasting electricity.
1. The check valve begins to "leak" at 120PSI. Feel free to overfill, but it will only waste electricity and give our team an easier time. Rules indicate that this must be the first thing in the pneumatics line after the compressor.
2. It's far easier to adjust the pressure sensors instead. I have ours set at 120 PSI (well, the point just before the valve starts to leak) and approx 100 PSI. This creates a buffer zone in case of miniscule leaks.
The code is smaller too...
Code:
Compressor:
if low_pressure = ON then Compressor_on
if high_pressure = OFF then Compressor_off
goto Compressor_return
Compressor_on:
compressor_relay = ON
goto Compressor_return
Compressor_off:
compressor_relay = OFF
goto Compressor_return
Compressor_return:
return
Sometimes the simplest approach is the easiest. I'll let you do the reading on how this works. If you just implement it, then it will not get you anywhere.
Anyways, FIRST is about sharing and it's nice to be of help. Just remember the KISS principle. Keep It Simple, Stupid. Another thing:
The technical manuals and team updates contain a ton of pneumatics information, READ THEM.
