How to Adjust Sensitivity?
Connect the power and signal cables, and adjust the water level of the container or pipe between the upper and lower edges of the black sensor film. Use a small screwdriver to rotate the potentiometer in the upper-left corner of the sensor. The anti-clockwise rotation sensitivity increases, and the clockwise rotation sensitivity decreases. As show below:
If the sensitivity is too low, turn the potentiometer counterclockwise until the red indicator lights on.
If the sensitivity is too high, turn the potentiometer clockwise until the red indicator off.
| After powered,level sensor doesn't react(water level to reach the sensor point indicator does not light, the sensitivity adjustment no response)
| ① Power is not connected
||Check and connect the power supply
| ②Power line + - Reversed
| ③ The power module is damaged
||Replace the circuit board where the power module is located
|④ Sensitivity is too low
|The indicator light is always on
|| ①Sensitivity is too high
|| Adjust sensitivity
| ② The initialization parameter is modified abnormally
|| Return to factory re-initialization
| ③ The sensor has a debris or other metal parts close
||Clean debris, and keep a certain distance from the metal parts
