Figure 341: Voltage profile causing a reset of the PICKUP signal for step 1, and inverse time delay
Definite timer delay
When definite time delay is selected, the function will trip as shown in figure 342. Detailed
information about individual stage reset/operation behavior is shown in figure 343 and figure 344
respectively. Note that by setting
tResetn
=
0.0s
, instantaneous reset of the definite time delayed
stage is ensured.
