11.6 SETTINGS 11.6.1 DESCRIPTION
The LPS-D performs protection functions in a power system according to the device settings values. The set-
tings are grouped into categories. The LPS-D has four settings groups. ALPS-Link provides for uploading the
settings from the device, modifying and these modified settings can either be downloaded to the device or
stored in a local file. The settings can also be loaded from these local files for download, etc.
11.6.2 UPLOAD SETTINGS
The settings can be uploaded from a connected device for viewing and modifying. An upload command will get
all the settings of all the categories from the connected device.
To upload settings, connect to the desired device. From the Device menu, choose the Settings item. From the
drop down menu, choose the Get Settings item. Choose the Upload item in the pop up menu. The Settings
dialog box with the uploaded settings will appear.
For an upload command, the device sends the latest settings available with it. That means, if you download
settings to the device and request an upload before sending the END message, the device will send those
downloaded settings.
In the Settings dialog box, you can modify the settings of a category you desire, save them locally, print them
and/or download them to the device.
From the Protection Category field, you can select a particular category. Click the scroll button to see the list
of available categories. Selecting a particular category displays only the settings of that category. You can view
and modify the values of the settings in that category only. If you want to view and modify all the settings of all
the categories, select All in the category field. See Figure 11–11: PROTECTION CATEGORY SCROLL LIST.
The dialog box has two parts, one has the list of all the settings selected in a category. This is more like a table
with the setting number, setting name, the setting value, the units of that setting and the new value if entered.
Once a setting is selected from the list, the second part of the dialog box displays the description of the setting
and the value(s) in that setting. You can change the value of a setting by entering the new value in the Change
to field. For some settings you can only choose one of the available values. If the text box is a combo box,
select the value from the list.
If the (?) button is displayed next to the field, the value is to be entered by you. Clicking on this button will dis-
play the valid ranges for that setting.
You can download the settings to the device by clicking the Download button. It is possible to download either
all the settings of all categories or only the changed values. When you choose the Download button, a dialog
box appears so that you can select between All and Changed Values only. Choose the Cancel button to quit
the download operation. You can also download Protection Settings, General Settings, or both categories.
After a successful download, a dialog box displaying the download status of the settings and requesting confir-
mation for sending an END message will appear. If you want to send the END message immediately, choose
the Yes button. If you do not want to send the END message immediately, choose the No button.
The END message can be sent explicitly by clicking on the END button in the settings dialog box.
The settings can be saved to a file. Choose the Save Locally button in the Settings dialog box. A File Save
dialog box appears where you can select the name and location of the settings file.
The Close button will close the dialog box. Any modifications to the settings (downloaded or not) will be lost if
not saved explicitly using the Save Locally button. If the settings are changed, a message box appears asking
if you wish to save the changes. Choose Yes to save the changes and a File Save dialog box appears. You
can choose No to quit without saving or choose Cancel to get back to the settings dialog box.
A hard copy of the settings can be obtained by choosing the Print button in the Settings dialog box.
