A couple of status screens at the time of shutdown.  Both the diode and crystal chillers are off.  Internal and external shutters
are closed.  The PSL Beckhoff computer will remain on.  The diode currents for all heads have been set to zero.

head 1 diode current: 65.0A
head 2 diode current: 59.8A
head 3 diode current: 59.8A
head 4 diode current: 59.8A

    Autolockers for the pre-modecleaner, intensity stabilisation and frequency stabilisation are off.  I took the input modecleaner
off line.
