Bio-Rad BioLogic Signal Import Module (SIM) - Manual (Page 43)

Position 1 on the AVR9-8 is the default position when the system is powered up or at the end of a
method run unless configured differently from the Edit User Preferences window, available from the
Options menu.
The valve uses 1/4-28 fittings and 1/16” (1.6 mm) OD PEEK tubing supplied with the fitting kit
when plumbing these valves.
Connect the AVR9-8 valve signal cable to any of the available automated valve connectors on the
back of the Workstation (ports 4, 5, or 6). If a Maximizer is in use connect to ports 7, 8, or 9 before
those on the Workstation. If more than three valves are desired, you may connect additional valves
to ports 4, 5, and 6 on the Workstation. All valves will be active.
