2.22.7 Flexible Function
The flexible functions can be used for various protection, supervision and measuring
purposes. Up to 12 flexible functions can be created in 7UT613/63x.
The flexible functions can be configured as independent protective functions (e.g.
further time overcurrent protection for measuring locations), create additional stages
for already existing protective functions or used for monitoring or control functions.
When determining the function scope (Section 2.1.3) the number of flexible functions
can be given.
Every flexible function is configured by defining analogue input value(s), type of mea-
sured value processing and logic link. Setting limit values, delay times, etc. can be
reset with the setting groups (see section 2.1.5 under „Setting Groups“)
2.22.7.1 Function Description
General When creating a flexible function you determine how the measured values (lead to the
device) are to be processed. The measured values can be directly detected (e.g. cur-
rents) or mathematically combined (e.g. positive sequence system of the currents or
current and voltage power).
The measured values can be monitored for overshooting or undershooting of a con-
figurable threshold value. Delays, blocking and logical configuration possibilities are
possible via user-definable logic functions (CFC).
A flexible function can signal the state that needs to be monitored, be used as control
function or initiate tripping of one or more circuit breakers. The latter starts the circuit
breaker failure protection with the trip command, if it has the same assignment char-
acteristics.
Measured Values All measured values given to the device can be used as analogue input quantities for
a flexible function.
Three-phase values can be processed together or individually. Together means that
the three-phase currents of a measuring point exceeding a common limit value have
to be monitored, but have to be announced and processed individually. All settings are
for all three currents. A flexible function can be created for each of the three phase
