    < p > < a href= "http://www.91se91.com/news/index_c.asp" > industrial sewing machine < /a > electric control system generally has the function of intelligent automatic fault detection. We can determine what faults the system appears according to the different alarm codes of the system, and further determine which part of the system has problems.

    After determining the fault code, we can use corresponding processing methods to maintain. Different brands of < a href= "http://www.91se91.com > > electric control system < /a > may adopt different fault codes, but the specific categories of their faults are not very different.

    In addition, there are obvious and specific notes on the instructions of the electronic control system.

    < /p >


    < p > industrial a href= "http://www.91se91.com/news/" > sewing machine < /a > during maintenance, technicians can observe the machine with vision and compare with the normal working condition of the system, so as to narrow down the fault area or locate the fault location directly.

    For example: observe whether the controller and the display surface have no scars, whether the plug is off or not, and whether the lead wire is disconnected, whether the components of the circuit board are burnt, broken feet, and pins collide.

    < /p >


    < p > sometimes the operator will replace the corresponding parts on the equipment by using new parts to determine whether the parts are faulty, the location of the fault or the specific components of the fault.

    During maintenance, we should start with large parts and replace them step by step until we find out the faults.

    This method is mainly used in the case of adequate fittings or good electrical control system.

    < /p >


    < p > for example, when maintaining the AC servo system, it is necessary to determine whether it is a system problem. Generally, the method of changing the normal control box is used to determine whether the fault is an industrial sewing machine or a control box.

    In the maintenance of circuit boards, this method is also used to replace the "suspected" fault components in the circuit with good components, observe the changes of the controller and determine the location of the fault.

    < /p >


    < p > sometimes the electromagnet function of the electrical control system of the industrial sewing machine fails to alarm. It can break the solenoid joint or further disconnect the supply voltage of the electromagnet so as to determine whether there is any fault in other circuits.

    When the AC servo controller works normally, the working voltage of each point in the machine indicates the working condition of the machine within a certain range. When the fault occurs, the working voltage will inevitably change.

    The measuring voltage method is to use multimeter to check whether the working voltage of each test point of the plug and circuit board in the machine is larger or smaller.

    When measuring, it is necessary to measure the AC voltage and DC voltage with different gears of multimeter.

    The voltage measurement method is usually measured under < a href= "http://www.91se91.com" > machine < /a > electrified condition. Therefore, attention should be paid to single handed operation, safety first.

    外貿單證流程是什么?

    外貿單證就是指在國際結算中應用的單據、文件與證書,憑借這種文件來處理國際貨物的支付、運輸、保險、商檢、結匯等。因其特殊性,需要不同于一般的單據,主要是運輸單據,包括提單、商業發票、匯票、裝箱單、產地證等。
