[BI_52b] is the binary input for inputting the normally closed contact of the circuit breaker;
[CLP.ShortRst] is the binary signal of the short resetting function;
[CLP.St_50/51] is the binary signal which denotes anyone of th e selected protective elements
picked up;
[CLP.Init] is the binary signal for initiating the cold load pickup logic function (for example, a
binary input signal from other relevant relay);
[CLP.En] is the logic setting of the cold load pickup logic function;
[CLP.Blk] is the binary signal for blocking the cold load pickup logic function;
“t
Cold
” is the setting [CLP.t_Cold], the time setting for ensuring the cold load condition is met;
“t
Rst
” is the setting [CLP.t_Rst], the time setting for resetting the cold load pickup logic
function;
“t
ShortRst
” is the setting [CLP.t_ShortRst], the time setting for fast resetting the cold load pickup
logic function.
3.11.2 Cold Load Pickup Logic Settings
All the settings of the cold load pickup logic are listed in the following table. For the information
