Group web page as shown below.
Figure 13-13. Current Differential Relay Settings Group web page
The above web page will allow the user to save up to four different sets of Current Differential settings
(Groups 0 thru 3). Once set, these groups can be changed “on the fly” to react to various operating
conditions removing the need to change web pages. Check “Group Switching Enable” to enter the
group switching mode. By default Group Switching is disabled and settings for Group 0 is enabled, if
necessary consult RFL before making any changes.
The separate groups of settings are stored on the Control Module and driven from the HMI logic
output based on the value of the HMI output bits selected. Values from 1 to 63 are available in the
drop down menus for the most and least significant bit.
