SMC Networks PF3A703H-L Operation Manual page 55

●When the set value and hysteresis of the switch output (OUT1/2) is set within the zero-cut range.
The operating point of the switch output will be changed, depending on the zero-cut setting value.
However, please note that the set value and hysteresis of the switch output will not be changed.
To maintain the on-off point, set the value and hysteresis without the zero cut-off range.
