③分析辅助电路
辅助电路包括执行元件的工作状态显示、电源显示、参数测定、照明和故障报警等。这部分电路具有相对独立性，起辅助作用但又不影响主要功能。辅助电路中很多部分是受控制电路中的元件来控制的。
④分析联锁与保护环节
生产机械对于安全性、可靠性有很高的要求，实现这些要求，除了合理地选择拖动、控制方案外，在控制线路中还设置了一系列电气保护和必要的电气联锁。在电气控制原理图的分析过程中，电气联锁与电气保护环节是一个重要内容，不能遗漏。
⑤体检查
经过“化整为零”，逐步分析了每一局部电路的工作原理以及各部分之间的控制关系之后，还必须用“集零为整”的方法检查整个控制线路，看是否有遗漏。特别要从整体角度去进一步检查和理解各控制环节之间的联系，以达到正确理解原理图中每一个电气元器件的作用。
