1. Before installation, please confirm whether the power supply voltage is consistent with the voltage indicated on the label.

2. The anti rotation level switch should be avoided from being installed at the feed inlet. If it cannot be avoided, a protective baffle can be installed to protect the blades from material impact.

3. When installed horizontally, the inlet of the junction box should be facing downwards vertically, and the cable fixing nut must be locked tightly. If possible, a rain cover can be added.

4. Confirm whether to install horizontally or vertically before installation.

5. When installed horizontally, the blades should be installed at an angle of 10-20 degrees downwards to reduce material impact.

The resistance rotary level switch uses a micro motor to drive the detection blades to rotate at a speed of 5-6 revolutions per minute after deceleration. When the level of the tested material rises and the rotation of the blades is hindered, the detection mechanism generates rotational displacement around the main axis. This displacement causes one of the micro switches to emit a material signal, followed by the other micro switch, cutting off the motor power and stopping it. As long as the material level remains unchanged, this state will be maintained indefinitely. When the material level drops and the detection blade loses its obstruction, the detection mechanism relies on the spring tension to restore its original state. Firstly, one micro switch activates the motor power supply to rotate it, and then another micro switch activates to emit a no material signal. As long as there is no material blocking the rotation of the detection blade, this state will continue.
