Blocking protection is used to energize rotational equipment that has not been active for an extended period of time. This is typically done to prevent bearings and seals from deteriorating prematurely. The input values Max Time Off (Default value = 7 Days) and Blocking On Time (Default value = 5 seconds) control the behavior of the output. The output is energized for the Blocking On Time if it has been off longer than the Max Time Off.
