How to install water level float switch?

Drainage and water supply wiring can be described as an art, the use of brown and black wires (normally open contacts) for drainage, the float in the lower level of the contact is not in the state, the float in the upper level, the contact is open; while the water supply requires the use of black and blue wires (normally closed contacts), the float in the upper level of the contact is not in the state, the float in the lower level, the contact is open.

When the buoy body sags, the black wire (common COM) and the brown wire (normally open NO) will be in the disconnected state, while the black wire and the blue wire (normally closed NC) will be in the connected state. However, when the liquid level sensor probe rises and the buoy body follows the float and goes up about 28°, the brown wire and the black wire will be closed and the blue wire and the black wire will be disconnected to achieve the control purpose. On the contrary, when the liquid level falls, the buoy body follows down until the buoy body and the horizontal line down to about 28 °, the control points to restore the starting state. This is even more magical than the organ garden in the cartoon! How to use the weight

The position of the weight of the hammer is installed in the need to control the water level at about 12. For example: a user water tank 2 meters, need to stop the water automatically when the water is full, then the hammer can be installed at 1 meter.

The installation method of the weight is very important, because the correct installation can ensure the normal operation and safety of the equipment. First, thread the float switch cable through the center concave hole of the hammer, then gently push the hammer so that the plastic ring embedded in the top of the hole is dislodged by the force of the cable head. Next, attach this dislodged plastic ring to the cable, then secure the weight as necessary to set the horizontal position and set the level difference in turn.

During this process, special care needs to be taken to avoid the use of intermediate connectors, and if a connector has to be used, the cable connector should never be submerged in water. Finally, pull the cable out by gently pushing the weight until the center of the weight snaps into the plastic, the weight will not slip as long as it is lightly snapped into the plastic ring. If the plastic ring is damaged or missing, it can be replaced with the same light bare copper wire snapped into the cable. In short, the correct installation method can ensure the normal operation and safety of the equipment, so it must be strictly in accordance with the requirements of the operation.
