Figure 259: Voltage profile causing a reset of the PICKUP signal for step 1, and inverse time delay
Definite time delay
When definite time delay is selected the function will operate as shown in figure 260.
Detailed information about individual stage reset/operation behavior is shown in figure
252 and figure 253 receptively. Note that by setting tResetn = 0.0s instantaneous reset
of the definite time delayed stage is ensured
