det 0 (shack PT100) (Dewar PT100 ovl) (wall manifold PT100)
det29 (shack AC vent PT100) (shack PT100) (VME trigger crate 3V)
LN supply ON (valve 2 in wall manifold) is c0.2/relay #1, i.e. open main supply to GRETINA with opv 1
NOTE: don't use 'cooldown' for manifold 0 (wall manifold). If bypass valve c0.3 is opened LN from the Dewar actually will flow back through valve c0.1 (even closed) into vent line, as Dewar pressure is higher the building supply pressure.

filling buffer Dewar: opv 0 & opv 3
NEVER open wall box valve 3 (opv 2), LN from buffer Dewar is then released into vault via exhaust!
