The Electric Cabinet consists of one or more low-voltage switchgear and related control, measurement, signal, protection, regulation and other equipment, and is fully assembled by the manufacturer with structural components. It can be manufactured by CNC engraving, sand casting, transparent acrylic(PMMA/PC) 3D Printing. The more common faults of automatic control equipment are: systematic equipment failure, random equipment failure. 1. Systemic device failure. Systemic equipment failure generally refers to the controlled equipment, such as CNC machine tools, if certain indicators in the work meet certain conditions, or exceed a pre-set limit or limit, there will be a specific equipment failure. This kind of failure is a more common fault phenomenon, in order to prevent or avoid the occurrence of such systematic equipment failure, the correct use in accordance with the operating specifications is a practical guarantee, and careful maintenance work should be done. 2.
