CRYOGENICS
Cryopump on a roughing manifold and they are to be put through a
FastRegen, then they must all be started and run at the same time so that
they can all be roughed at the same time. This also means that if there is a
Cryopump in the process of FastRegen, then no other Cryopump on that
roughing manifold can start a FastRegen until that Cryopump is finished.
This is not true for Full regeneration. Full regenerations can be started and
stopped at any time, even if another pump on the same roughing map is in
regeneration.
