1、导轨式升降机厂家http://www.sdjwsjj.com/介绍有些电路短路，触点粘合，导轨式升降机开关不开等，这种短路不发作大电流，一般表现为电梯失控或电路上呈现某一继电器不能打开。
Guide rail type elevator manufacturers introduced some short circuit, adhesive contact, elevator guide rail type switch etc., this short circuit does not produce high current. In general, the for elevator control circuit or present a relay can not be opened.
2、导轨式升降机厂家谈到电源短路，短路后发作极大的短路电流，能将熔断器熔体焚毁；由于缺陷表象明显，对导轨式升降机电路剖析即能查看清楚。
Guide rail type elevator manufacturers talked about the power of short circuit, short circuit attack great short-circuit current, fuse burned; due to the obvious defects of representation, to guide rail type lifter circuit analysis can clearly see.
3、导轨式升降机厂家http://www.sdjwsjj.com/建议也可以根据继电器的有关电路进行分段断开，逐步将缺陷查清。
The guide rail type elevator manufacturers recommendations can also be based on the relay of the circuit to be broken open, and gradually identify the defects.
