When the XUV-detector has to shut down unexpectedly, it can happen that the Mesytek power supply crashes and can't be 
communicated with. If this happens the Mesytec PS needs to be restarted from hand inside of the ESR. This can be done by 
restarting the crate located at the bottom of the XUV-detector. 

This crash happened during the night shift today and the Mesytec should be restarted today as soon as possible. For 
example when the laser stabilization gets fixed.

In normal operation this should never happen if no mistakes are made.
