1) ON delay time : It outputs after setting delay time in spite of output condition. During ON delay time, output lamp is turned on with output after flickering in fast cycle

※

2) Min OFF Time : It lets output not occur within min. OFF time after it is turned off. During min. OFF time, output lamp is turned on with output after it flickers every 1 second intervals

※

3) Min ON Time : It is for avoiding frequent ON/OFF of control output and maintains ON condition in spite of OFF condition during Min ON Time after being turned on.

(In case of sensor error, OFF at once)

※

4) Output at Sensor Error : In case of sensor error such as open wire/short, it sets ON/OFF status of the related output.
