Local control of loadshedding/boosting

Local loadshedding/boosting control of the relay are via using the opto inputs assigned in
input mask. The three levels can be selected by energising one of the three opto input
channels as required by the user. If more than one opto inputs are energised at any one
time then the relay acts on the setting nearest to 0.
For example, if
Level1 = 3 % and Level 2 = +9 %, then level 1 is selected OR
Level1 = 3 % and Level 2 = –3 % then level 2 is selected. The –ve setting has priority
over the +ve setting if both values are equally nearest to 0.
The following cell locations are assigned in the input masks.
