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.
