Common problems and solutionsIE1Textile Testing Instruments, Testing Equipment Manufacturer


Symptom: No output or incorrect outputIE1Textile Testing Instruments, Testing Equipment Manufacturer


Possible reasons:


1) The corresponding error of the measuring range leads to a PLC calculation error. Please note some technical indicators for the measurement range. IE1Textile Testing Instruments, Testing Equipment Manufacturer


2) The wiring method is wrong or the wiring order is wrong. IE1Textile Testing Instruments, Testing Equipment Manufacturer


3) The power supply voltage is wrong (24V power supply for 0-10V models). IE1Textile Testing Instruments, Testing Equipment Manufacturer


4)The distance between the transmitter and the collector is too large, which will cause signal interference. IE1Textile Testing Instruments, Testing Equipment Manufacturer


5) The SPS capture port is corrupted. IE1Textile Testing Instruments, Testing Equipment Manufacturer


6) The device is damaged. IE1Textile Testing Instruments, Testing Equipment Manufacturer


Note: IE1Textile Testing Instruments, Testing Equipment Manufacturer


1. The RS485 communication line must use a shielded twisted pair and two 250Ω termination resistors are required if necessary. IE1Textile Testing Instruments, Testing Equipment Manufacturer


2. The operating environment should be free from conductive dust, metal-corrosive and insulation-damaging gases, and avoid direct sunlight and rain. IE1Textile Testing Instruments, Testing Equipment Manufacturer


3. Do not apply this product in an environment of extreme temperature and humidity (working in a high humidity environment of more than 90%RH for a long time will cause drift) . IE1Textile Testing Instruments, Testing Equipment Manufacturer


4. Avoid long-term exposure of components to salt spray, acid, or oxidizing gas (sulphur monoxide, hydrochloric acid, etc.) environments. IE1Textile Testing Instruments, Testing Equipment Manufacturer
