Pick-up
The
U
set
setting parameter controls the pick-up of the U> function. This defines the maximum allowed
measured voltage before action from the function. The function constantly calculates the ratio
between the
U
set
and the measured magnitude (
U
m
) for each of the three voltages. The reset ratio of
97 % is built into the function and is always relative to the
U
set
value. The setting value is common for
all measured amplitudes, and when the
U
m
exceeds the
U
set
value (in single, dual or all voltages) it
triggers the pick-up operation of the function.

Selects the delay type time counter. The selection possibilities are
dependent (IDMT, Inverse Definite Minimum Time) and independent (DT,
Definite Time) characteristics.

The time dial/multiplier setting for IDMT characteristics. This setting is
only visible when "IDMT" is the selected delay type.

The definite time operating delay. This setting is active and visible when
"DT" is the selected delay type.
When set to 0.000 s, the stage operates as instant without added delay.
When the parameter is set to 0.005...1800 s, the stage operates as
independent delayed.

Determines the time allowed between pick-ups if the pick-up has not led
into a trip operation. During this time the START signal is held on for the
timers if the delayed pick-up release is active.

Selects the resetting characteristics. Either time-delayed or instant after
the pick-up element is released. If activated the START signal is reset
after a set release time delay.

Selects the operating timer resetting characteristics. When actived, the
operating time counter is reset after a set release time if the pick-up
element is not activated during this time. When disabled, the operating
time counter is reset directly after the pick-up element reset.

Selects the time calculation characteristics. If activated, the operating
time counter continues until a set release time even if the pick-up
element is reset.
The pick-up activation of the function is not directly equal to the START signal generation of the
function. The START signal is allowed if the blocking condition is not active.
Read-only parameters
The relay's
Info page displays useful, real-time information on the state of the protection function. It is
accessed either through the relay's HMI display, or through the setting tool software when it is
connected to the relay and its Live Edit mode is active.
