ATM is a complex mechatronics equipment, composed of many parts. The task of the diagnosis center is to quickly determine the cause and components of the fault, and quickly eliminate the fault so that the machine can resume normal work as soon as possible. Before starting to troubleshoot, ask the operator about the situation of the ATM some time before the failure or the moment the failure occurs, and then ask the on-site maintenance engineer what methods and measures have been taken to repair. After understanding the on-site situation, for some simple faults, experienced engineers may have analyzed the cause of the fault and can provide remote technical support and guidance to the on-site engineer, and may be able to eliminate the fault. Even if the fault cannot be eliminated remotely, you can have a preliminary analysis of the machine fault before going to the site and make corresponding preparations (such as accessories, tools, etc.). If you manually adjust the switch or disassemble the components without careful observation, the fault may become more serious. Therefore, carefully observe the indicator lights, transmission components, control boards, power cords and data cables and plugs related to the fault before you start to see if there is an obvious fault indicating the point of failure. This will help to find the cause of the failure as soon as possible. The current financial self-service equipment is highly intelligent, and its self-diagnosis ability is strong. Some fault conditions and diagnosis results will be recorded in the ATM's electronic flow or printed on the transaction log. Carefully check the ATM's electronic log and print out the ATM. From the transaction log, it is possible to obtain useful information for troubleshooting. If you cannot determine the point of failure by using the above methods to eliminate the fault, you must use the instrument to detect each part, whether the voltage is normal, whether the control board is normal, whether the components meet the standard value, and whether the data line is well connected, and use the instrument to determine The specific location of the fault. Some methods can also be used in maintenance to speed up the search for fault points and improve maintenance efficiency. 1. Touch method: For some situations where the fault location cannot be determined by observation, you can feel it by touching it with your hands. For example, touching the surface of a chip or component can sense whether the chip or component is heating (in the power-on state), so as to know which chip or component is damaged or in a critical state. Touch the vacuum nozzle of the ATM cash-out module to know whether the vacuum pump relays the electromagnetic switch or not, so as to determine whether it is normal when the cash is sucked. 2. Comparison method: If there are normal parts that are the same as the abnormal parts, the difference between the two can be compared to determine the cause of the failure. 3. Subs...
