Fault phenomenon: all are out of the light is not normal, on the high side, string into the current meter, ammeter display abnormal, or a current for a long time, or, sometimes, is not controlled.
The cause of the problem: the main reason is that laser't type selection, main board, wiring board, power supply or is connected line and cooling water circulation system failure cause.
Method: 1, parameter Settings, see the laser type is correct, it is a major cause of continuous light failure.
2, pull the nine core line, see if there is a line is loose.
Connection is not reliable.
3, on the power supply line (
Removing, according to the laser power supply of some key, is to analyze the power or motherboard failure.
4, some normal, explain the power supply trouble-free.
5, some also not normal, suggests that there is something wrong with the power supply.
6, when the power supply is normal, connected to the line of control, switch control pin in a patch panel is measured with a multimeter, no light, in a normal more than 4 v, the voltage is lower than 3 v, the main output is not normal;
Light, the foot should be under 2 v voltage, higher than 2.
5 FuShu out is not normal.
In July and see if the water cycle is normal, water, water protector if there's any problem.
