1、类故障点可能发生在开关、极限位置、安全保护和现场操作上的一些元件或设备上。

其原因可能是因为长期磨损，也可能是长期不用而锈蚀老化。对于这类设备故障的处理主要体现在定期维护，使设备时刻处于完好状态。对于限位开关尤其是重型设备上的限位开关除了定期检修外，还要在设计的过程中加入多重的保护措施。

2、第四类故障点可能发生在PLC系统中的子设备。

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。

1, Class failure points may occur in switches, limit positions, safety protection and field operation on some components or equipment.

The reason may be because of long-term wear and tear, or it may be rust and aging after long-term use. The troubleshooting of such equipment faults is mainly reflected in regular maintenance to keep the equipment in good condition at all times. For limit switches, especially limit switches on heavy equipment, in addition to regular maintenance, multiple protective measures should be added in the design process.

2, the fourth type of failure point may occur in the PLC system of the sub-equipment.

Such devices as junction boxes, wire terminals, bolts and nuts. The reason for this kind of failure in addition to the production process of the equipment itself is also related to the installation process, such as some people think that the wire and screw connection is the tighter the better, but it is easy to lead to disassembly difficulties in the secondary maintenance, and it is easy to cause damage to the connector and its nearby parts when vigorously disassembling. Long-term ignition, corrosion and other causes of failure. According to engineering experience, this kind of fault is generally difficult to find and repair. Therefore, the installation and maintenance of the equipment must be carried out in accordance with the installation process of the installation requirements, leaving no hidden dangers of the equipment.以上翻译结果来自有道神经网络翻译（YNMT）· 通用场景
