※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.
※5) Manual Output Mode : OFF : Output by PV / ON : Output by MVI,MV2 (-R4 model)
