为了安全起见,要求柴油机正常工作后,启动机不能再动作。此要求可以通过电器系统控制实现,既简单又方便(见附图)。启动时,点火开关上的启动端子C与电源端子B接通,启动端子C与继电器JD2的电源3由导线连通,由此电流通过继电器JD2的常通触点5到达继
For safety reasons, the diesel engine is required to work properly, the starter can no longer move. This requirement can be achieved by controlling the electrical system, which is simple and convenient (see attached figure). When starting, the start terminal C on the ignition switch is connected to the power terminal B, the start terminal C and the power supply 3 of the relay JD2 are connected by wires, and the current passes through the normally-on contact 5 of the relay JD2 to reach the relay
