Operating Principle

 DLC-4U-M-2W 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, 1 buzzer relay, and Max. 2 relays to control Max. 2 ea of its connected pumps.

 It is designed for both alternating and sequential controls and either mode can be selected by using its internal jumper pin. Each mode runs in accordance with below orders. ("P" : Pump)

   Control order in Alternating mode     
      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 ...

   Control order in Sequential mode     
      Phase 1 : P1 start - P2 also start - Both stop 
      Phase 2 : P1 start - P2 also start - Both stop 
      Phase 3 : P1 start - P2 also start - Both stop 
      Phase 4 : Repeating Phase 3 ...
