Two-column selection valve
The firmware does not recognize the 2-column selection valve (6 port, 2
position) option. Instead, the option is controlled via one of the four I/O event
switches on the separations module's rear panel. You select one column by
turning the switch to Off and the second column by turning the switch to On.
Three-column selection valve
The 3-column selection valve selects any of three column positions. It is
preconfigured before shipment, but you can reconfigure it. For more
information, see "Connect the column selection valve" on page
