M7B—E型洗片机的烘干加热电路由200V固态继电器U1加热电阻丝R1过温保护开关S7准备继电器K1的常开触点0V连接形成。由于过温保护开关S7损坏(该开关是过温弹起 ,手动复位的开关 ,损坏后无法按下) ,向北京保税库订购时因无件需等两个月 ,考虑为
Drying heating circuit of M7B-E type chip processor is formed by 200Vsolid state relay U1heating resistance wire R1overheat protection switch S7preparation relay K1 normally open contact0V connection. Due to the damage of the overtemperature protection switch S7 (this switch is an overtemperature bounce and a manually reset switch, which cannot be pressed after being damaged), there are no parts waiting for two months when ordering from the Beijing Bonded Warehouse. Consider this as
