5, Debugging method and switch wiring diagram
Return the adjusting nut to a state of basic weakness, connect the C, NO, NC wires of the switch to the signal light. Observe the status of the signal light, connect the signal light to a green light (C is the common terminal, and when C is connected to NC at the factory, the green light will light up), and adjust the adjusting nut up and down according to the set point indicator to set it to the desired set point. (The downward pressure increases and the upward pressure decreases).
