Now that we are trying to stay locked on some maintenance days, I've added a "LIGHT_MAINTENANCE" state to the SEI_ENV guardian. This state turns off the end station stage 1 sensor correction and the all of the CPS_DIFF controls. It doesn't include all of the normal environmental tests, but will do the LARGE_EQ transition that we added a while ago, if the peakmon channel goes above 10 micron/s. It won't go to the normal eq state.

I don't think this will work as when the microseism is high, but Oli has been able to do an alignment and work on getting the IFO locked, while people were cleaning the endstations and working in the high bay.

Recovery to normal operations is the same as the normal maintenance state, select AUTOMATIC on SEI_ENV and INIT.
