PSL restarted 
after the power glitch the PSL had to be restarted.  Justin and I followed the procedure to start it in low power mode, we reset the kepco HV supply to 200mA, as Christina wrote in her alog instead of the 400mA in the procedure.  We also reset the LRA, even though we were starting it in low power mode I wasn't sure if the beckhoff computer had lost power or not.  

The only hitch was that we couldn't open the external shutter, the situation was similar to  last time , 
H1:PSL-MIS_FLOW_OK was 0, although H1:PSL-MIS_FLOW_INMON was within the limits.  We tried the reset button on the medm screen, which didn't do anything, and we tried caput which also didn't change the value.  Jim and Dave managed to open it, they will write a log about what they did.  

The PMC is now locked, but the medm screen reports -30W transmitted power.  H1:PSL-PWR_PMC_TRANS_GAIN is now -0.024, while it was 1 before the power glitch.  

The ISS is not staying locked, which was also the case before the power glitch.

The safe.snap files for the PSL are out of date, Dave did a burt to friday and the PMC transmission is now making sense. The ISS is also locked now.

The new configuration for the shutter is that you have to press the reset button on the MEDM laser screen each time the system is restarted. Did you had any other problems?

The power supply should be set to 400mA as in the procedure, I think this isn't right in my alog. 

Please go ahead and create new safe.snap files.
