General information about system settings

System settings

The system settings

  • define settings for alarms and warnings

  • select the data that will be stored in result files

When to change the system settings

Each system has a set of default settings.

  • Changes to the default settings should be made when the system is installed.

Certain system settings may need to be adjusted in the following cases:

  • If system components are changed: e.g. the alarm and warning limits

  • For specific separation runs: e.g. the monitor and curve settings.

Note: Only the settings for the selected components will be shown for strategies where you select the system components.

How to change the default settings

The table below describes the two different ways to change the default system settings.

Change

Effect

To assign a new value to a parameter within a method.

The specific change is valid only until End in the method. After End the parameter returns to its default setting.

Note: Only some parameters can be changed in the method.

To assign a new value to the system setting.

The new value is valid for all runs and remains until you change the value again or return the setting to its default value. See "How to assign a new value to a system setting" below.

Like the default values, the new value can be changed temporarily in a method.

Note: You must have System settings authorization to assign a new value to an actual system setting.

How to assign a new value to a system setting

The table below describes how to assign a new value to a system setting in the System Control module.

Step

Action

1

Select System:Settings.

Result: The Instructions dialog box for the connected system opens. The illustration below shows the dialog box opened with the Alarms group of settings selected.

2

Click the radio button to select one of the following instruction groups:

  • Alarms

  • Specials

  • Monitors

  • Curves

Result: The instructions for the group are displayed. The parameters are listed below each instruction. The title bar of the dialog box shows the selected instruction group.

3

  • Select a parameter from the list.

  • Change the setting value in the Parameters field.

Result: The parameter is updated with the new value in the list.

4

Click the Set Selected Parameter To Strategy Default Value button to return to the default value (if necessary).

Result: The default setting that was defined in the system strategy is restored. Only the selected parameters will be restored.

5

Click OK.

Limits for monitor signals in methods

If the system strategy allows, limits for certain monitor signals can be set in the method. These limits will only work locally in the method and override the global settings as long as the method is in operation. This feature can be used to set the pH warning threshold to one value during the process operation and another during the system cleaning.
