Setting [ZACbyCH_CH*]
The setting is for Zero-ampere control. By this control, the value of flowing current will be
set 'Zero' unconditionally, when the CB is open in the CH. This control can operate when
On is set for the setting [ZACbyCH_CH*]. On the other hand, set Off when this is not
required. Remind that the user has to set either NO, NC, or Both for the setting [CB_CH*]
in order for this control.
