- Wiring
- Emergency stop button has been pressed
Possible Solutions:
- Ensure all interlocks are closed, front lid and rear door magnet.
- the magnet can shift when changing the tube – ensure it lines up with the black sensor on the left hand side of the door as you look at the back of the machine
- Check tube for damage (use caution as you are near High Voltage)
- Cracks or leaks in the tube
- HV leads are securely connected (red and black leads to either end of the tube)
- Ensure chiller is turned on and there are no blockages
- You should see a steady flow of coolant through system
- Ensure Chiller Signal Cable is plugged in at chiller and laser machine.
- Visually check cable for any damage.
- Ensure laser output is turned on within the job file
- RDworks, select profile, is output option set to yes
- Ensure power is being supplied to the PSU. (use caution as you are near High Voltage)
- use a multimeter
- Ensure all wiring on the laser tube is securely fitted. (use caution as you are near High Voltage)
- HV leads to Tube ends
- Are the leads securely attached
- Is the lead still taped to the tube?
- Are the Power supply leads connected to HV leads (grey brown screw in connectors that connect the red and black HV lines to the machine)
