After the PSL was shut off today from work on the interlock system (currently relevant alog), Jason and I were looking at how a few of ther autolockers were turned off and noticed that the ISS autolocker was not turned off. Digging into the LASER_PWR node we saw that this is where the FSS & PMC autolockers were turned off, but not the ISS. There was a comment saying that we don't need to turn it off, but Jason says this is not correct. We added it in to be turned off and also noticed that the channel that it checks before turning these off is out of date. Updated. Below is the svn diffs of our changes. These changes are committed and loaded in.
