Summary
A roughing map describes all of the pumps that share a roughing manifold.
Up to five roughing maps can be set up on a multi-pump On-Board System
through the Network Terminal.
If several Cryopumps on the same manifold begin FastRegen, then they
must all be started at the same time. The Network Terminal coordinates the
simultaneous starting of pumps through Regeneration Groups as
described within this section.
