Installation

Set the Current Scaling Parameter Using the Front Panel

1. Press enter to move to the setting state of the desired menu (for example, 

CONF/CURRENT SCALING). 

The Pick text appears in the upper-left part of the display.

2. Press info. Enter the password that is associated with the configuration 

level by pressing the arrow keys (default value is 0002). 

3. Press enter. 

4. Press up and down to scroll through the parameters. 

A parameter can be set when the background color of the line is black. If 
the parameter cannot be set, the parameter is framed.

5. Press enter to select the desired parameter (for example Inom). 

6. Press up and down to change a parameter value. 

If the value contains multiple digits, press left and right to shift from 
digit to digit, and up and down to change the digits. 

7. Press enter to accept a new value. 

To leave the parameter value unchanged, exit the edit state by pressing 
cancel.

Changing the Parameters

IMPORTANT

Almost all parameters and settings can be viewed and modified using the 
front panel interface. Because of the vast selection and modification 
capabilities of the Protection System, the SetPointPS software tool is 
recommended for monitoring and configuring the settings within the 
device.
