1、導軌式升降機廠家http://www.ydpcb.com.cn/介紹有些電路短路，觸點粘合，導軌式升降機開關不開等，這種短路不發作大電流，一般表現為電梯失控或電路上呈現某一繼電器不能打開。
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、導軌式升降機廠家談到電源短路，短路后發作極大的短路電流，能將熔斷器熔體焚毀；由于缺陷表象明顯，對導軌式升降機電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、導軌式升降機廠家http://www.ydpcb.com.cn/建議也可以根據繼電器的有關電路進行分段斷開，逐步將缺陷查清。
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.
