问:XG501型500mAX线机一般摄影正常,但在滤线器摄影时,按曝光手开关PA,保险丝6RD烧断,怎样检修? 答:电路如图所示。当按下曝光手开关PA时,则辅助继电器SFJ经由:101—SFJ—250—PA—102通电。其常开触点SFJ_4闭合。如此时已按下技术选择开关2号按钮,则电动诊视床滤线器摄影继电器HLJ经由:102—PA—250—SFJ_4—256—FZJ_3—282—2号按
Q: The XG501 500mAX line camera is normally photographed normally. However, when the line filter is photographed, press the exposure switch PA and the fuse 6RD is blown. How do you troubleshoot? Answer: The circuit is as shown in the figure. When the exposure hand switch PA is pressed, the auxiliary relay SFJ is energized via: 101-SFJ-250-PA-102. Its normally open contact SFJ_4 is closed. In this case, the technical selection switch No. 2 button has been pressed, and the electric medical bed filter device photographing relay HLJ is pressed by: 102-PA-250-SFJ_4-256-FZJ_3-282-2.
