5.3.3 Setting Auxiliary (SV-3 or Splitter) Valve Control
Control for an auxiliary valve is selected by pressing the right soft key.
This option is available if a valve is connected to the Auxiliary port on
back of the Econo Gradient Pump. The valve type is automatically
recognized. The SV-3 diverter valve must be connected if you wish to
program a collection window with either the model 2110 or 2128
Fraction collector. With an auxiliary valve and Gradient Mixer
attached, the LCD display would look like this:

5.4 PROGRAM MODE
The Econo Gradient Pump can be programmed to perform up to six
sequential steps automatically. Selections made in the Setup screen
will be reflected in the Program screen. The Program screen will
display the program step (either time or volume), the %B if a Gradient
Mixer is present, and the flow rate/motor speed (RPM.) For the first
program step, the time (or volume) parameter is -0- and is not
editable. Here is an example of a Program screen where volume and
flow rate have been selected in Setup and a Gradient Mixer is
connected.
