Setting Notes

General
During configuration of the scope of functions for the device (address 126) the available characteristics were
determined. Depending on the configuration and the order variant, only those parameters that apply to the se-
lected characteristics are accessible in the procedures described below.
At address 2601 Operating Mode you switch time overcurrent protection ON or OFF.
If not all stages are required, each individual stage can be deactivated by setting the pickup threshold to ∞. But
if you set only an associated time delay to ∞ this does not suppress the pickup signals but prevents the timers
from running.
One or several stages can be set as instantaneous tripping stages when switching onto a fault. This is chosen
during the setting of the individual stages (see below). To avoid a spurious pickup due to transient overcurrents,
the delay SOTF Time DELAY (address 2680) can be set. Typically, the presetting of 0 is correct. A short delay
can be useful in case of long cables for which high inrush currents can be expected, or for transformers. The
time delay depends on the severity and duration of the transient overcurrents as well as on which stages were
selected for the fast switch onto fault clearance.
