Section 4 Gradient Pumping for Pressure, Flow, and Concentration Modes
Two-pump concentration gradients enable proportionate use of two
different fluids that combine at the mixer (refer to Figure 4-4 and
Figure 4-5).
This type of pumping uses flow mode (FG) only. A single-pump gra-
dient program is based on either pressure or flow, and controlled by
either time duration (in minutes) or rate of change (units per minute).
The controller's memory can contain a total of up to 200 steps. One
program can contain from 1 to 200 steps.
When operating in Gradient Mode, any connected pumps not used for
gradient are inoperable.
1. To access the gradient programming menus, press PRGM GRAD,
then DUAL SYSTEM GRADIENT (1) and CONTINUE (C).
The home screen will appear, with FG (Flow Gradient) in the
upper left corner.
2. Press PROGRAM (A).
3. At the prompt, enter a file number between 1 and 99. This is the
file name of your program, and can be the name of a new
program you are creating, or a stored program you want to edit
or run. Press ENTER.
If a selected stored program is in a different mode than that of the
controller selected in Step 1, a brief notification will appear, display-
ing the controller's mode and the file's mode. If you attempt to run
the program without changing the mode of either it or the controller,
the program will not run, and the same message will be displayed.
4. To enter the flow rate for this program, either press
FLOWRATE (A) and use the number keys and Enter, or for
maximum possible flow, simply press MAX (C).
