If they are loose, please tighten; if they are short circuit, you can use a multimeter to
examine the wire;
Use a multimeter to check the wire is normal or not, act as follows:
Measuring the laser power supply port: IN port - G port, TH port –G port (TL port – G
port) whether the voltage changes normal or not before and after work;
Before work (V) After work (V)
IN port - G port 4.98 0.49
TH port - G port 0.09 3.58
TL port - G port 3.68 0.1
If the wiring is ok;
Go to the Step 4 and check:
Step 4 Check the signal output of the main control panel is normal or not;
1.
If you use laser1 output on the laser controller for machine, set the interface into laser2
output, set the power input of software into POWER2,and set POWER2 display on the control
panel, then test is it normal to use the laser2 output;
Specific location, please refer to the following pictures:
2.
If there is laser beam with laser2 output, then we can make sure the laser1 output of
controller is fault; if there isn’t laser beam with laser2 output, it should be the main control
panel fault without optical signal, and then you need to replace the laser controller.
3.
If you check the machine by following our lesson plan, but still unable to pick out the fault
parts, please contact our Technical Support Division, and send e-mail to:
