Up to four separate and distinct Protection Settings Groups can be programmed and stored in the LPS-D.
Selection of the settings group to be used can be made via the keypad, through the communications link or
through external contacts applied to selected programmable inputs.
The General Settings category applies to all schemes and all settings groups regardless of which Settings
Group is selected.
