Fault detection and judgment: the phenomenon analysis, possible controlling motor positive and reverse bidirectional thyristor has breakdown, caused by losing control effect. Check the bidirectional thyratron VSI and VS2, found the bidirectional thyristor VS2 short circuit between anode and cathode. VS2 out of control, after the replacement of VS2, fault is still. Check the VT4 trigger circuit of transistor, R47, VT5 and resistance, R48, R51, R52. R47 found resistance value. XAWservice manual download site
