Parameter settings of both analog value comparators:
A simple circuit can be implemented if a switching point of
the controller is assigned to the digital switching point of the
analog input. This switching point is 8 V DC (CL-DC1,
CL-DC2) and 9.5 V (CL-AC1).
Parameter settings:
Example: Analog value comparator, detection of
operating states
Several analog value comparators can be used to evaluate
different operating states. In this case 3 different operating
states are evaluated.
