Section 3 Single & Multiple Independent Pump Operation
3.5.3 STORE The store key is operational when in the programmed gradient
mode. It is used to save the program gradient parameters and
exit the programming (parameter entry) mode.
3.5.4 LIMITS The controller allows the user to set the minimum and maximum
flow rate limits, the minimum and maximum pressure limits,
and the maximum rate the pump will run while controlling the
pressure in constant pressure mode.
• When using a single controller to operate multiple
pumps, you need to select the appropriate pump before
setting any pump parameters. The available pumps will
be displayed above the softkeys. These selections correspond
with the connector that the pump control cable is
plugged into on the rear panel of the pump controller. To
select a pump, press the softkey under the pump designation.
The top line of the screen will indicate the pump
which is currently selected.
• The high and low limits you set cannot exceed the pump
specifications.
To set the limits
1. Press the LIMITS key on the keypad. To display the Limits
menu, Figure 3-7, enter the number of the limit you wish

five limit setpoint menus to appear, MAX PRESS, MIN
