7th. Installation method
Open installation holes on the panel where the sensor needs to be installed, and place the nuts in the upper and lower
fixing holes of the sensor or in the front and rear fixing holes to tighten to achieve up and down or front and rear fixing.
8th. Instructions method
When the sensor is working normally, put the liquid pipe into the pipe clamp wire groove. The instruction light is on
and the output is high, indicating that there is liquid passing through the current position of the tube. The indicator light is
off and the output is low, indicating that no liquid is passing through the current position of the tube .
9th. Sensitivity setting steps
The sensitivity of the product shall be calibrated in strict accordance with the standard before delivery; However, in the
actual use process, it may be necessary to fine tune the accuracy of sensitivity according to the on-site environment to achieve a
better experience effect.
1. Connect the sensor circuit as required.
2. Align the liquid level in the liquid pipe with the center of the sensor.
3. Turn on the power supply to power up the sensor.
4. After the mark line of the sensor (sensitivity calibration line) and the sensor gnd wire are shorted for about 1 second, the
mark line is converted from high level to low level, and the LED lamp of the sensor flashes to indicate that the sensor enters the
calibration state. After entering the calibration state, the mark line and the gnd wire are separated, and the calibration is
completed successfully when the LED lamp is always on.
Precautions: In normal use, the mark wire of the sensor(sensitivity calibration line) can only be suspended in the air and cannot
be connected to the positive or negative pole of the power supply.
（
It is recommended that the sensitivity calibration line be
connected to the negative pole (GND) through a switch. When setting the sensitivity, the switch should be closed, and it should
be disconnected in normal use.
