P0923ZJ这类设备如接线盒、线端子、螺栓螺母等处。这类故障产生的原因除了设备本身的制作工艺原因外还和安装工艺有关，
如有人认为电线和螺钉连接是压的越紧越好，但在二次维修时很容易导致拆卸困难，大力拆卸时容易造成连接件及其附近部件的损害。长期的打火、锈蚀等也是造成故障的原因。根据工程经验，这类故障一般是很难发现和维修的。所以在设备的安装和维修中一定要按照安装要求的安装工艺进行，不留设备隐患。3. The third type of fault point may occur on some elements or equipment in switch, limit position, safety protection and field operation
The reason may be due to long-term wear, or corrosion and aging due to long-term use. For example, the distribution cart on the kiln tail ball storage of the production line moves frequently, and the dust on the site is large, so the contact of the proximity switch is deformed, oxidized, and blocked by dust, resulting in poor contact of the contact or insensitive action of the mechanism. The treatment of this kind of equipment failure is mainly reflected in regular maintenance to keep the equipment in good condition at all times. For limit switches, especially those on heavy equipment, in addition to regular maintenance, multiple protection measures should be added in the design process.
4. The fourth kind of fault point may occur in the sub-equipment of PLC system
Such equipment as junction box, wire terminal, bolt and nut, etc. The causes of such failures are not only related to the manufacturing process of the equipment itself, but also related to the installation process. For example, some people think that the tighter the wire and screw connection is, the better, but it is easy to cause difficulties in disassembly during secondary maintenance, and it is easy to cause damage to the connector and its nearby components during heavy disassembly. Long-term sparking and corrosion are also the causes of the failure. According to engineering experience, such failures are generally difficult to find and repair. Therefore, the installation and maintenance of the equipment must be carried out according to the installation process required by the installation, without leaving any hidden danger of the equipment.
