on the proportional gain and integral time settings.

Window Comparator (Disconnection Detection ODc/OIDc/O2Dc)

•The Inverter activates the window comparator output when the O/OI/O2 analog input value is
within the upper and lower limit levels of the window comparator. This function allows you to
monitor analog input based on the desired level (e.g. to detect a disconnection).
