The loss of load supervision function LOFLPTUC is used to detect a sudden load loss which is considered as a fault condition.
LOFLPTUC starts when the current is less than the set limit. It operates with the definite time (DT) characteristics, which means that the function operates after a predefined operate time and resets when the fault current disappears.
The function contains a blocking functionality. It is possible to block function outputs, the definite timer or the function itself.
