CHARACTERISTICS
If the U2>BLK1 enabling parameter is set to ON and a binary input is designed for logical block
(Block1), the protection is blocked off whenever the given input is active.
The trip timer is held in reset condition, so the operate time counting starts when the input block goes
down.
[1]
The enabling parameter is available inside the Set \ Profi le A(or B) \ Negative sequence
overvoltage - 59V2 \ U2> Element \ Setpoints menu, while the Block1 function must be assigned to
the selected binary input inside the Set \ Inputs \ Binary input IN1(x) menus (IN1 or INx matching).
Note 1 The exhaustive treatment of the logical block (Block 1) function may be found in the “Logic Block” paragraph inside CONTROL AND MONITOR-
ING section.
