FLOAT INSTALLATION GUIDELINES:

As per the name Cable Float Switch, it has 3 important parts,

  • Body of the float – Where the NO/NC Element is molded and activated by a steel ball during the low and high levels of the tank.
  • Weight – Weight plays an important role. The length between the weight and body of float determines Low and High Levels of the tank. Ensure weight should be fixed at distance from the body such that it should not move during operation.
  • Wire – Wire should be fixed to the tank with help of Glands in case of PVC Tanks or through bolts and clamps in case of the civil tank. Wire length from a fixed point to weight is also important. Cable Float Switch has 3 wire common, NO, NC. Different manufacturers have different color codes. Floats supplied with QM-WLC-Eco will have wires as per below color code. (Subjected to changes in the future). Common – Black color wire.NC – Red Color wire at UP position.NO – Blue/Yellow Color wire at UP position. User need not worry about the NC & NO position and can simply follow the color code in the wiring diagram to ensure proper working.
