Subject: MCautolocker getting stuck 

I've noticed this a couple of times today - when the autolocker runs the mcdown script, sometimes it doesn't seem to actually change the various gain sliders on the PSL FSS. There is no handshaking built in to the autolocker at the moment. So the autolocker thinks that the settings are correct for lock re-acquisition, but they are not. The PCdrive signal is often railing, as is the PZT signal. The autolocker just gets stuck waiting to re-acquire lock. This has happened today ~3 times, and each time, the Autolocker has tried to re-acquire lock unsuccessfully for ~1hour.

Perhaps I'll add a line or two to check that the signal levels are indicative of mcdown being successfully executed.
