can be active. The “dynamic” thresholds are active for the set hold time for the
“dynamic parameters” (see Section 3.12.5, (p. 3-76)) and the “normal”
thresholds are active when no hold time is running. If the residual current
exceeds the set thresholds, timer stages are started. Once the time delays have
elapsed, a signal is issued. If the operating mode of the general starting decision
is set to With start. IN/Ineg, a trip signal is issued as well. The timer stages can
be blocked by appropriately configured binary signal inputs. In addition these
timer stages can also be automatically blocked by single-pole or multipole
starting (depending on the setting).
