Today I set up the LASER_UP state which monitors the system once the locking is done.  The power output and PZT voltage output are monitored and if they exceed allowed values guardian goes back to the FIND_LOCK_POINT state to try to find a new locking point.

I also added another assert class that monitors the chiller temperature setpoint throughout the locking process including the final LASER_UP state, so that the temperature set point doesn't run away to a value that can cause the chiller to trip off.  When a chiller setpoint that is outside of the allowed range is detected it goes back to the DOWN state, resets the chiller setpoint and then starts moving back up through to LASER_UP.

Guardian has now also been set up for the X-arm laser, tested, and is now working.

Dave has taken a safe snap of the system in the DOWN guardian state to record new gain settings and the filter settings for when the servos are off.
