Setting for second turn point in the bias axe of the differential
characteristics.

Setting for the second slope of the differential characteristics.
The pick-up settings can be selected via setting groups. The pick-up activation of the function is not
directly equal to the TRIP signal generation of the function. The TRIP signal is allowed if the blocking
condition is not active.
The following figure presents the differential characteristics with default settings.
