In addition to the menu options, certain functions and modes are
selectable from the front panel keyboard.
These keys place the system in Constant Pressure Mode or Constant
Flow Mode, respectively. Information for these operating modes can be
found in Section 3.10 "Operating Modes".
This key is used to place the pump system in Gradient Mode. For com-
plete information about gradient programming, refer to Section 4
"Gradient Pumping for Pressure, Flow, and Concentration Modes".
The HOLD key is used while a gradient is running. When HOLD is
pressed, the program clock freezes and current gradient parameters
are maintained.
To resume the gradient, press the HOLD key again or the RUN key.
The RECALL key can only be used when the pump(s) are stopped or
when in HOLD Mode. The RECALL key is used to recall a previously
programmed gradient. When you select this option, the controller
automatically loads the gradient and switches the pump to program
Gradient Mode.
1. Press RECALL and use the number keys to enter the number
name of the gradient you wish to recall. Press E
2. If you enter a number of a gradient that does not exist, the con-
troller briefly displays the message "FILE NUMBER DOES NOT
EXIST." It then assumes you will be creating a new gradient
under that number and displays the program gradient run
screen.
The key is operational in the programmed Gradient Mode. It is
STORE
used to save the program gradient parameters and exit the Pro-
gramming (parameter entry) Mode.
The REFILL key manually places the pump in Refill Mode.
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 currently
selected pump.
• The maximum and minimum limits you set cannot exceed the
pump specifications.
