CHARACTERISTICS
For every of the two thresholds the logic block can be set.
Logical block (Block1)
If the U>BLK1 and/or U>>BLK1 enabling parameters are 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 parameters are available inside the Set \ Profi le A(or B) \ Overvoltage - 59 \
U> Element (U>> Element) \ Setpoints menus, 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.
