No more vacuum upstream of Experimental hutch (after Be-window) and big primary pump in fault state

The big primary pump at the end of the Optics hutch needs for its operation cooled water. In the case of a water cut, the pump should be preferably shut down. If not done it will stop in a fault state. To make it working back (once water is circulating again), one should first stop it which will erase fault state and that put ON again. And wait...until vacuum reach 10-4 level to continue the experiment.
