2.26.10 Set Points (Measured Values)

SIPROTEC 4 devices allow thresholds (set points) to be set for some measured and metered values. If one of
these set points is reached or is exceeded positively or negatively during operation, the device generates an
alarm which is displayed as an operational indication. This can be configured to LEDs and/or binary outputs,
transferred via the interfaces and interconnected in DIGSI CFC. In addition you can use DIGSI CFC to config-
ure set points for further measured and metered values and configure these via the DIGSI device matrix.
In contrast to the actual protection functions the limit value monitoring function operates in the background;
therefore it may not pick up if measured values are changed spontaneously in the event of a fault and if pro-
tection functions are picked up. Furthermore, since an indication is only issued when the set point limit is re-
peatedly exceeded, the limit value monitoring functions do not react as fast as protection functions trip signals.
