The Pump User Interface (Dashboard Panel)

Module Graphic

The items in the pump graphic have the following meaning and function:

The level of solvent in the bottle is denoted by the gray area. When the solvent level falls below the specified volume, the area turns yellow. When the bottle is empty, the area turns red. Clicking the solvent bottle displays the Bottle Fillings dialog box. The tooltip for the bottle shows the solvent name.

Indicates that the ISET option is installed but with no active method (light gray) or installed and active (dark gray).

The pressure setpoints. The red line shows the current maximum pressure limit; the gray area shows the current pressure (also shown as text).

The current solvent flow rate (in mL/min) is displayed above the pressure display.

Instrument Signals

The following pump signals are displayed:

**Table:** Pump signals (isocratic pump)
Flow	The current solvent flow rate (in mL/min).
Pressure	The current pump pressure (in bar, psi or MPa, see Instrument Configuration).
Ripple	The current ripple (in %).
Pressure Limit	The current maximum pressure limit.

**Table:** Pump signals (quaternary pump)
Flow	The current solvent flow rate (in mL/min).
Pressure	The current pump pressure (in bar, psi or MPa, see Instrument Configuration).
Ripple	The current ripple (in %).
Pressure Limit	The current maximum pressure limit.
Composition A:B	The contributions of channels A and B to the current solvent composition.
Composition C:D	The contributions of channels C and D to the current solvent composition.

Context Menu

The context menu of the dashboard panel contains the following commands:

	Control	Displays the pump's Control dialog box.
	Method	Displays the pump's Method Setup dialog box.
	Set Error Method	Sets the method that is loaded if an error occurs to the method that is currently available in the hardware.
	Identify Device	Causes the LED on the front of the module to blink for a few seconds.
