Mechanical part description

Note: When the M18 product and M30 product have 4-20mA analog output, the meter connection method is different from that of the 550,600 product. Since the output terminal of the M18 and M30 products is powered by VDD, as shown in Figure 1, the meter should be connected to the power supply port. Between the output terminal and the output terminal, the connection instruction diagram is shown in Figure 2:

4. Sensor function description

Switch point and advance interval setting and adjustment of switch output and analog output products

Switch value and analog output can be set using the adjustment terminal, specifically, there are 8 working modes that can be set.

The specific setting method of each type of bean flour is the following steps.

In the first step, the user selects a distance set by himself, or puts the sensor into a lost wave state.

The second part, connect the calibration terminal to the power supply or GND, keep it connected until the yellow light flashes (if the wave is lost, the red light flashes).

In the third step, the user selects the second distance set by himself, or lets the sensor enter the lost wave state.

The fourth step, connect the calibration terminal to GND or power supply (the state is different from the second step), keep it connected until the yellow light flashes (if the wave is lost, the red light flashes).

There are 8 working modes of switch output

1. Window normally open mode (analog output products are in positive linear working mode or distance measurement mode).

2. Window normally closed mode (analog output product is in negative linear working mode or liquid level measurement mode).

3. Single point normally open mode.

4. Single point normally closed mode.

5. Single-point normally open mode with large hysteresis interval.

6. Single point normally closed with large hysteresis interval mode.

7. Whether to detect the normally open mode.

8. Whether to detect normally closed mode.

Description of RS485 output model products.

There are 3 working modes,

1: Automatic measurement mode, the sensor continuously measures the liquid level and distance, and the user can read the measurement results through the 485 interface at any time.

2: If the user does not initiate a 485 communication, the sensor will initiate a measurement and report the result.

3: Sleep mode, the product enters sleep mode, the user first wakes up the sensor through the 485 interface, and then initiates a measurement and obtains the result before the sensor sleeps again.

5. Installation conditions

When installing, pay attention to protect the surface of the sensor to avoid injury. If you work in an environment with heavy volatile gas or dust and heavy condensation, you need to clean the surface of the sensor regularly to avoid sensitivity reduction or failure to work. The installation thread should not be over-tightened, which will cause the sensor to be pressurized and not work properly.
