VACUUM PUMPS

The ADCS-601-AF vacuum pumps are stand alone products for which separate Operation and
Maintenance manuals are available with much more complete information than is included in this
manual. A copy of the manual is provided on the ADCS-601-AF Support CD.

There are two vacuum sources in the ADCS-601-AF system.

- Utility vacuum source

: The utility vacuum source provides vacuum to the pressure

controllers so that they can control pressure under atmospheric pressure. The utility vacuum
source is a dry, scroll pump that is normally located under the Reference Bench and has
single connection to the Control Cabinet rear panel.

- Reference vacuum source

: The reference vacuum source provides vacuum to the

reference circuit of the PG7601 and FPG8601 pressure standards for operation in absolute
mode. The reference vacuum source consists of a roughing pump and a turbo molecular
pump. The roughing pump is a dry, scroll pump located under the Reference Bench. The
turbo molecular pump is mounted to the bottom surface of the Reference Bench and includes
a Controller mounted in a bracket under the Reference Bench.

See the original manufacturer Operation and Maintenance Manuals for additional information on the turbo
molecular pump and turbo pump controller.
