故障现象:日产ORION VH-3C型录象机,按面板上各键均有指示,FF、REW、PLAY(或REC)全不能进行控制,3秒钟后自动关机。经检查发现,该故障是因录象机长期使用跨轮磨损严重,使得跨轮与供带盘(REW)或收带盘(PLAY,FF)之间打滑,不能产生足够的摩擦力来带动带盘转动。微处理器从带盘传感器中检测出带盘停转的信息,并发出停机信号。
Symptom: Nissan ORION VH-3C video recorders, according to the instructions on the panel keys, FF, REW, PLAY (or REC) can not be controlled, 3 seconds after the automatic shutdown. The inspection found that the fault is due to long-term use of video recorders across the wheel wear serious, making the cross between the wheel and the supply reel (REW) or take-up reel (PLAY, FF) between the slip, can not produce enough friction to drive the belt Turn the plate. The microprocessor detects the reel stop information from the reel sensor and issues a shutdown signal.
