FPG8601 Manifold Connection
Connect the normally closed pneumatic valve to the bottom of the lower mounting post.
Connect a piece of the supplied flexible tubing to the drive port of each valve.
Connect valve driver 9 to the vacuum reference valve with the supplied tubing.
Connect valve driver 10 to the bypass valve with the supplied tubing.
Connect valve driver 11 to the vacuum control reference valve with the supplied tubing.
Connect the open end of the reference vacuum sensor valve to the front of the mounting post. Make
sure the vacuum reference sensor is in the vertical position.
Always mount the vacuum reference sensor in the orientation used for zeroing. A significant zero-shift can
occur when the sensor is not mounted in the orientation in which it was zeroed (see Section 8.3). It is
recommended that the sensor be zeroed in the vertical orientation. When zeroed horizontally, the rotation
of the sensor also affects the zero. This makes it difficult to mount remove and remount sensor without
affecting the zero.
