Operating Principle

 DQC-4U-MC-2W Series Level Controller gets signal from each point of the sensor installed in the tank and displays the level of
the liquid in the tank with its LED points.

 As a 2-wire-type controller, the controller is responding only to its compatible level sensor's current output which was converted from its original contact switching signal, by the sensor's current converter.
 LED display enables you to read the current status correctly and easily.
 This is designed to be used for 1 alarm relay and Max. 2 relays to control Max. 2 ea of its connected pumps.

 It is designed for the alternating control in accordance with below orders. ("P" : Pump) 

      Phase 1 : P1 start - P2 also start - Both stop 
      Phase 2 : P2 start - P1 also start - Both stop 
      Phase 3 : P1 start - P2 also start - Both stop 
      Phase 4 : Repeating Phase 2 ...
