Binary Pump Dashboard Panel

Module Graphic

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

	Indicates that an External Contacts board is installed.
	When the solvent level falls below the specified volume, the yellow warning is shown; when the bottle is empty, the red error is shown. The tooltip for the bottle shows the solvent name. If Level Sensing is configured, clicking on the solvent bottle displays the Level Sensing Assignment dialog box. Otherwise the Bottle Fillings dialog box is displayed.
	(G4220A/B, G7120A and G7132A) Indicates that the ISET option is installed but with no active method (gray) or installed and active (black).
	Indicates the presence of a solvent selection valve. Use the context menu to switch the valve.
	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.

The following pump actuals are displayed:

Flow	The current solvent flow rate (in mL/min).
Pressure	The current pump pressure (in bar or psi).
Ripple	(Not G4220A/B, G7120A or G7132A) The current ripple (in %).
Tuning <Channel>	(G4220A/B, G7120A and G7132A) Indicates the tuning efforts of 1290 Infinity pumps. For pumps operating as expected, the signal should stay in a range of -1 to +1 within the full scale of -2 to +2.
Pressure Limit	The current maximum pressure limit.
Composition A, B	The percentage contribution of each of the solvent channels to the current solvent composition. When a solvent selection valve is fitted, the channels are shown in the graphic.
Purge Status	The current status of the pump purge. (G4220A/B only)
Prepare Pump	Displays the current pump preparation operation and the remaining duration for Purge or Conditioning, or the run time for Prime. (G7120A and G7132A only)
Mixer	The installed mixer type. (G4220A/B, G7120A and G7132A)

The context menu contains the following commands:

	Control	Displays the pump's Control dialog box.
	Method	Displays the pump's Method Setup dialog box.
	Error Method	Set Error Method Sets the error method to the method that is currently available in the hardware. The error methods are loaded automatically on all modules if an error occurs. Clear Error Method Removes the currently loaded error method.
	Identify Device	Causes the LED on the front of the module to blink for a few seconds.
	Switch On/Off	Toggles the status of the pump, on or off.
	Switch Solvent Selection Valve A/B	Switches the solvent selection valve to the alternative position. These menu items are present only when a solvent selection valve is configured.
	Bottle Fillings	Displays the Bottle Fillings dialog box.
	Level Sensing Assignment	Displays the Level Sensing Assignment dialog box. The menu item is present only when Level Sensing is configured.
	Zero	Displays the Zero dialog box. The menu item is present only when Level Sensing is configured.
	Purge On/Off	Allows you to control the purging of the system. (G4220A/B only)
	Prime On/Off	Allows you to prime the pump heads if they are full of air. (G4220A/B only)
	Conditioning On/Off	Allows you to switch pump conditioning on and off. See Conditioning for more information. (G4220A/B only)
	Prepare Pump	Displays the Prepare Pump dialog box. (G7120A and G7132A only)
	Seal Wash Prime	Allows you to ensure that all air bubbles in the seal wash lines are removed (for example, after the seal wash solvent bottle has been refilled). (G7120A and G7132A only)
