5. Description of Sensor Functions
Adjusting the analogue output.
The analogue output can be programed as the user want. Such as
working at switch output or working at liner output all the
parameters can be set by the RS485 interface.
There is 8 types of output functions can be programed.
All the setting routine as follows,
step 1 set one pointed distance by the RS485,
step 2 set another pointed distance by the RS485.
Step3 set the output type liner or switch, and set the related
output options
Step4 reboot the sensor.
1. Window mode normally-open and liner mode positive slope output
function.
2. Window mode normally-closed and liner mode negative slope output
function.
3. Single switching point, normally-open function.
4. Single switching point, normally-closed function.
5. Single switch point with hysteresis gap normally-open function.
6. Single switch point with hysteresis gap normally-closed
function.
7. Detection of object presence-normal open function.
8. Detection of object presence-closed open function.
Switching point, Setting distance only after power on. The internal
clock can assure can't be changed after 5 minutes after power on.
If want to change the switching point, the user can only setting
the request distance after power restart.
For the RS485 output type.
There are 2 kinds of working style,
One for auto measure, the sensor will measure the distance or level
repeatedly, and the measurement period can be set by the UART. The
measure result can be fetched every time.
The other style is power save mode when the sensor is sleep, until
the sensor received the inquiry command with pre-code.
Communication protocol is Modus-RTU.
For example the measure result can be read by access the register
0x101 by Modbus protocol.
For more information please contact us for the software engineering
guide.

7. Installation conditions
If the sensor is installed at the environment temperature fall
below 0℃, It should do well on the protective measures. In case of
direct mounting of the sensor in a through hole using the steel
nuts, it has to be fixed at the middle of the housing thread.
