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
selected 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 pick-up due to transient overcur-
rents, the delay SOTF Time DELAY (address 2680) can be set. Typically, the presetting of 0s is correct. A
