What should I do if there is a temperature alarm?

in FAQs about Laser Marking, ,

Confirm whether the laser power supply is normal.

If it is normal, you need to make a short connector for the laser marking control board. CON2 10 and 11 are shorted, 14 and 16 are shorted, then open the Ezcad to start mark to see if there is an error prompt, if there is no prompt, continue to check the laser or try to restart the laser.
