logic of this zero-phase signal, turn the "Zero-point signal logic reverse" relay on or off as shown in the
following table.
If the same input is specified for both the near-point signal and the zero-phase signal, the logic of the zero-
phase signal will be specified by the device of the near-point signal (DOG), and not by one of the following
devices. In this case, the operation will be performed at the front and rear ends of the near-point signal
(DOG) without using the zero-phase signal. This is similar to the operation of the ZRN instruction.
