Subject: PMC got unlcoked 

Came this morning to find the PMC was unlocked since 6AM. Laser is still on, but PMC REFL PD DC shows dead white constant 0V on PMC screen. All the controls on the PMC screen show constant 0V actually except for the PMC_ERR_OUTPUT which is a fast channel.


Is PSL Acromag already failing?


I restarted the IOC but it didn't help.

I am now rebooting c1psl... That seemed to help. PMC screen seem to be working again. I am able to lock the PMC now.

IMC was locking easily once some switches on the MC servo screen were put to normal states.

TTs were grossly misaligned. Onces they where aligned, arm cavities were locking easily. Dither align for the X arm is very slow though...
