例1.故障现象:该机送入录像磁带后,自动保护停机。 分析检修:打开上机盖,观察录像带进入带舱后的动作过程,发现当带舱下降到位后,穿带电动机旋转,带动机械部件将磁带拉出,当穿带到半穿带位置时,发现穿带电动机并不停转,而是继续转动;当机械工作方式开关圆形盒内箭头指向“4”时,穿带电动机才停止转动,此时录像磁带停留在非正常位置,录像机自动保护停机。 Example 1. Symptom: The machine into the video tape, the automatic protection downtime. Analysis and maintenance: Open the upper cover, observe the video tape into the cabin after the action process and found that when the tape cabin down in place, wear a motor rotation, mechanical parts driven tape pulled out, when worn to wear half-belt position, found Wear the motor does not stop, but continue to rotate; when the mechanical work switch circular box arrow pointing “4”, wear a motor to stop rotating, this time the video tape to stay in an abnormal position, the recorder automatically protects the shutdown .
