Re: Fans from the PCM?

Consider the intent of the 'motors must be connected through controllers' rule. It is there to stop mechanisms from moving when the robot is disabled. It is a safety concern and a game-play concern. Is it dangerous or unfair to allow a cooling fan to remain on when the robot is disabled? No, unless you jam your finger into one, then it stings like crazy. Fans used to cool motor controllers stay on when the robot is disabled, I see no intent in the rules that you prevent a fan from cooling a compressor from running while the robot is disabled.

FWIW we used a fan hard-wired to the PDB last year with no comments from any inspectors.
