The System Control module

Introduction

The System Control module is used to perform and monitor separation runs.

The System Control panes

The System Control module contains four different display panes that can be opened all at once or in any combination:

  • The Run Data pane.

  • The Curves pane.

  • The Flow Scheme pane.

  • The Logbook pane.

The Run Data pane

The Run Data pane displays the current values for the selected run parameters. The values are updated at regular intervals, which are defined in the system strategy. See the illustration below:

The Curves pane

The Curves pane displays monitor signal values graphically. See the illustration below:

The Flow Scheme pane

The Flow Scheme is a graphical representation of the chromatography system. During a run, the Flow Scheme displays open flow paths in color. Monitor signals can be displayed numerically. See the illustration below:

The Logbook pane

The Logbook pane displays all actions during a separation run, e.g. method start and end, base instruction, method instructions and manual instructions such as Pause or Hold. See the illustration below:

The Status bar

The Status bar in the bottom of the System Control module displays the current status of the separation run. See the illustration below:

The current system status is represented by the colored dot:

  • A green dot represents a running system.

  • A red dot represents a system in Pause state.

  • A yellow dot represents a system in a Hold state.

  • A white dot represents a system in an End state.

Toolbar icons in the System Control

The table below describes the toolbar icons in the module:

Icon

Function

 

The Run icon opens the Run dialog box, which shows all available methods. If a method is loaded, Run Setup opens.

 

The Hold icon suspends execution of the method, while liquid is still pumped at the current flow rate and eluent concentration.

 

The function of the Pause icon depends on the strategy. The Pause icon suspends execution of the method and stops all pumps so that the system comes to a standstill.

 

The Continue icon resumes the execution of a paused or held method.

 

The End icon terminates the method execution and puts the system into an End state.

 

The Customise Panes icon opens the Customise Panes dialog box, which is used to select the display panes that are open.

 

The View Documentation icon opens the documentation pages. Run notes can be entered in the Notes page and settings can be changed.

 

The View Properties icon opens the Properties dialog box, which is used to control the data display in the System Control panes.

 

The Connect System icon is used to connect a system.

 

The Disconnect System icon is used to disconnect the system.

 

The Take Control of the System icon is used to leave the view mode for the system and change into a control mode.

 

The Leave Control of the System icon is used to leave the control mode for the system and change into a view mode.
