How to troubleshoot and solve equipment failures?

When equipment fails, first observe the fault phenomenon, such as whether the equipment stops running, whether there are abnormal sounds or smells, whether there are problems with the packaging quality, etc. Then, find the possible causes of the failure according to the equipment's instructions and maintenance manual. Common causes of failure include electrical failure, mechanical failure, sensor failure, etc. If it is a simple failure, such as loose sensors, packaging material blockage, etc., the operator can troubleshoot and solve it by himself; if it is a more complex failure, such as motor damage, controller failure, etc., professional maintenance personnel are required to repair it.
