Machine short circuit detection
Machine short circuit detection
Question: customers receive the machine, the insurance replacement insurance is immediately burned, burned.
Reason: machine parts or lines have a short circuit phenomenon.
Solution: need to find the location of the specific short circuit.
1 the machine does not connect the power cord. Check the links in each location using a universal table. The multimeter in the following position, two pen will alarm a bit short.
一
2 first check if there is a short circuit in the laser power supply (Figure two). If the alarm is short circuit. Need to pull off the two power lines, and then again to detect whether there is a short circuit (Figure three), if no alarm to detect the power supply line down again.
二
3 check if there is a short circuit in the DC power supply (Figure four). If the alarm is short circuit. Need to pull off the two power lines, and then again to detect whether there is a short circuit (Figure five), if no alarm again to detect the power supply cord down the power supply
三
4, if more separate distribution are not the problem, you need to check the cable, to check whether the existence of the breakage phenomenon of the line and then find replacement
