GSK983Ma-V User:

Hello sir, the GSK983Ma-V shows SYSTEM ERROR as soon as turning it on, the alarm code is 902, and the spindle is running the wrong direction, neither the RESET button nor the STOP button can stop it, what should we do?

It seems the problem come from the main board of the GSK983Ma-V milling CNC controller, please send it back for check.
