Common high-temperature industrial television faults and troubleshooting methods
Summary: After mastering some of the causes and solutions for high-temperature industrial television failures, if similar situations are encountered in later work, the difficulties can be easily solved. Common failures and assistant methods are as follows:
Master some High-temperature industrial television After understanding the causes and solutions of common malfunctions, future similar issues will be easily resolved. Common malfunctions and solutions are as follows:
(1) When High-temperature industrial television there is no image output from the camera, check the video head and video cable connections to ensure they are secure.
(2) When the operator function keys fail, first check if the operator's indicator lights are on normally; then check if the control cable is connected incorrectly and if the control relay is functioning properly.
(3) When there is no image on the monitor, first check if the controller power supply and system power supply are normal, and if the camera power supply is normal; then check if the monitor is in "AV" mode.
(4) When the device automatically exits abnormally, do not push the system into the furnace wall before all faults are eliminated. Be sure to use the manual method to exit. After cutting off the system power, turn on the power and check according to the above procedure.
(5) When the monitor image is unclear or the image is reduced, this may be due to furnace dust or tar contaminating the objective lens components. In this case, the protective device should be withdrawn from the furnace, the power should be cut off, the protective device opened, the camera removed, the lens checked, and cleaned with lens paper.
(6) When High-temperature industrial television the image is distorted, first check the grounding of the equipment and eliminate poor grounding or repeated grounding; then check if the spacing and routing of the power lines comply with electrical specifications; then check if any strong magnetic field equipment shares the power supply system, and consider adding an isolation transformer for separate power supply to the system.
