Re: Off robot air compressor

Brian,
In order to keep in line with other parts of the manual (electrical) and in keeping with good electrical practice, the best solution is for the limit switch to be monitored by the RC and controlled through a spike. This switch does not handle the current reguired for compressor start and there can't be anything that controls a spike except the RC.

In addition, for all teams using the compressor for the first time, it is acceptable to replace the 20 amp fuse with a 20 amp circuit breaker on the spike that is used for the compressor. The start current for the compressor can exceed 20 amps for a very short time and the fuse will fail after a few starts.

<R65> ...
The fuse on the Spike relay for the air compressor may be replaced with a 20 Amp Snap-Action circuit breaker.
