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.
