Installation Instructions
No output or output error
possible reason:
1) The range corresponding error causes the PLC to calculate an error.
2) The wiring method is incorrect or the wiring sequence is wrong.
3) The power supply voltage is incorrect (24V power supply for 0~10V models).
4) The distance between the transmitter and the collector is too long, causing signal disturbance.
5) The PLC collection port is damaged.
6) Equipment damage.
Notes
1) The aging test before use is not less than 48 hours;
2) Electrolyte leakage will cause injury, please do not disassemble the sensor at will;
3) The sensor should avoid contact with organic solvents, paints, chemicals, oils and high-concentration gases;
4) The sensor should not be immersed in an oxygen-free environment for a long time,
otherwise it will damage the performance of the sensor;
5) It should not be used for a long time in an environment containing corrosive gases,
corrosive gases will damage the sensor;
6) It is forbidden to store and use in high concentration alkaline gas for a long time;
7) The air inlet holes must not be blocked or contaminated.
