on vidio Level relay, operating principle # liquid level relay VSR-05 Tense

 Connect the device according to the diagram.

 The relay will not energize when it is
 energized if the water level in well between low

 electrode and the lower electrode. When the water
 levet touches to the upper electrode relay activates
 and the water level drops and drops below the

 the low electrode relay is deactivated.
  When the relay is activated 1(16NC) and
 2(15-com) contact poles are open circuits 2(15-com)

 and contact poles 3(18-no) become shorted.
  When the relay has deactivated 1(16-NC) and
 2(15-com) numbered contacted poles are short

 circulated 2(15-Com) and 3(18-no) numbered
 the contact poles become open circuits.When the relay has deactivated 1(16-NC) and

 2(15-com) numbered contacted poles are short
 circulated 2(15-Com) and 3(18-no) numbered
 the contact poles become open circuits.
  Sensitivity adjustment: You can adjust the
 sensitivity by button (100KΩ). Make sure the
 the electrodes are in contact with the water while you are
 adjust the sensitivity level. Then turn the knob towards 100KΩ. When the device detects the electrodes pulls the relay.
 In order to provide the device to detect the electrodes, the resistance value of the liquid must be lower than the adjusted value
 beforehand.
