pneumatics module/robot inspection

[chaparoel]

Hello,
This year our team is not going to use pneumatic so we have the question that if it is obligatory to put the pneumatic control module to pass the inspection.The issue is that we currently only have a burned control module so we are seeing if we need to get another in order to pass inspection.

Thank you very much

No it is not necessary to have the PCM on your robot.

That's weird. Our team had the same problem where our PCM randomly stopped working... We replaced it with a new PCM and it started working fine so yeah...

We ran into a similar problem, as stated by my teammate.

Maybe try asking around? We also practiced at another team's field today, and we are using their backup for now.Once ours is shipped, we will replace their backup with our new one.

Also, any idea how yours blew? I'd hate to have it happen again if it was preventable...

R88 The pressure switch requirements are:
A. It must be Nason P/N: SM-2B-115R/443
B. It must be connected to the high-pressure side of the pneumatic circuit (i.e. prior to the pressure regulator) to sense the “stored” pressure of the circuit.
C. The two wires from the pressure switch must be connected directly to the pressure switch input of the PCM controlling the compressor or, if controlled using the roboRIO and a Spike relay, to the roboRIO.
D. If connected to the roboRIO, the roboRIO must be programmed to sense the state of the switch and operate the relay module that powers the compressor to prevent over-pressuring the system.

The PCM is by far the easier method. If you don't use one, you do have to use a Spike Relay for compressor control. You may replace the 20 amp fuse with a 20 amp breaker for this application only. All other motors must only use the 20 amp fuse.
