Compressor control system
Thread Content
The process air compressor we use stopped operating twice due to a secondary temperature interlock, but the temperature sensors (with temperature sensitivity) were found to be in good condition. The temperature sensors that were removed after the shutdowns were then reinstalled in their original positions, and it has been three months since then with no problems. Please analyze what exactly the problem is.
It is very likely that the wiring was loose originally, and false signals caused an incorrect shutdown
There is looseness at the connection points or oxidation/rust on the joints, etc
