How to troubleshoot the electrical system of the injection molding machine?

Sometimes the failure of the electrical control system is more complicated, and now the injection molding machines are all controlled by microcomputers, and the software and hardware are intertwined. When encountering a failure, you are the first to think that you are nervous. When troubleshooting Consider, think about.

Most of the faults in the operation of the injection molding machine are caused by the poor contact of the switch. Therefore, when judging the fault, the internal circuit and power supply part should be checked first according to the fault and the indicator light in the cabinet. Safety circuit, AC and DC power supply, etc., if you are familiar with the circuit, you can solve it soon.

Some faults are by no means as simple and intuitive as the relay circuit. Many protection links of the PC injection molding machine are hidden in its software and hardware systems. The faults and causes are strictly corresponding to the results and conditions. When finding faults, the order is very important. The relationship between them is associated and guessed, and the doubts are eliminated one by one until the fault is eliminated.
