丹东XXQ-2505机准备灯不亮的故障比较常见,它影响到整机的正常工作,针对这一问题,现按电路原理图找出了一个简易快速解决办法,简介如下: 由电路原理图可以看出,电源接通后,由电子计时器供给电容C_(228)一个充电电压,C_(228)两端电压逐渐上升,经过一段时间后电压充到一定大小,一使BG_(211)管导通,于是继电器J_(201)动作,触点J_(201-1)闭合,准备灯亮,J_(201-2)闭合使J_(204)动作,高压部分具备正常工作条件。所以J_(201)是否工作则是一个关键,BG_(211)、R_(238)、R_(237、226)、CID_(202)、R_(230)、W_(206)的异常都将影响J_(201)的工作。
Dandong XXQ-2505 machine lights do not light the more common failures, which affect the normal work of the machine, in response to this problem, according to the circuit schematic to find a simple and quick solution, as follows: The circuit diagram can be It can be seen that after the power is turned on, the capacitor C_ (228) is supplied with a charging voltage from an electronic timer, and the voltage across C_ (228) gradually increases. After a period of time, the voltage is charged to a certain magnitude, Then, the relay J_ (201) is actuated, the contact J_ (201-1) is closed, and the ready lamp is on. J_ (201-2) is closed and the J_ (204) is actuated, and the high voltage part has normal working conditions. Therefore, whether J_ (201) is working or not is a key issue. The abnormalities of BG_ (211), R_ (238), R_ (237,226), CID_ (202), R_ (230) and W_ (206) 201) work.
