Connect the lower KF16
manifold tube to the KF16
low control port on the
FPG8601 mounting post.
Connect the FPG8601
vacuum isolation valve
(valve 9) to the bottom of
the lower mounting post at
the KF25 connection.
Mount the valve so that
main body is vertical and
the lateral KF25 port is to
the left (viewed from the
front).
Connect the 1/8 in.
pneumatic line labeled 9
from the FPG8601
vacuum isolation valve
(valve 9) to the V9 port on
the front of the FPG8601.
Level the FPG8601 using
the bubble level on the top of the platform and the back two leveling feet.
3.3.10.3 INSTALL THE REFERENCE VACUUM CDG ASSEMBLY
The PG7601 and FPG8601 reference vacuum CDGs are delivered with an
isolation valve connected to them. This valve is normally closed and serves
to maintain vacuum on the CDG at all times as exposing the CDG to
atmospheric pressure will cause zero shifts. New CDGs are shipped with
vacuum behind the isolation valve. Do not break the valve fittings or operate
the valve without establishing vacuum first.
Connect the FPG8601 reference vacuum CDG assembly (CDG, KF16
clamp/o-ring, KF16 pneumatic valve) to the KF16 port on the front of the
mounting post. Install so that the CDG body is in the vertical position.
Connect the CDG electrical cable to the VACUUM SENSOR electrical
connector on the front of the FPG8601 platform.
Connect the 1/8 in. pneumatic line labeled 12 from the CDG isolation valve
(valve 12) to the V12 port on the front of the FPG8601.
