Troubleshooting
Below are some possible problems along with a list of things to check if the problem occurs.
No laser emission 3 minutes after start-up
1.
Verify the remote interlock connector is connected and restart the laser.
2.
Verify that autostart is enabled. Click the restart button in the Monitor software or send the command
“@cob1” to force a restart of the laser.
3.
Ensure the laser has adequate heat sinking.
4.
Verify the supply voltage is within the range stated in section 6.6.
5.
Check the base plate temperature (this is displayed in the Cobolt Monitor™ software). If it is outside of the
range 20-50 °C the laser may take longer to stabilize the temperature, or be unable to do so.
6.
Send the command “f?”
7.
If fault code 1 is returned, check that the heat sink is adequate and that the ambient temperature is under
40°C.
8.
If fault code 3 is returned, see interlock fault checklist.
9.
If fault code 4 is returned, there may be a problem with the constant power system.
10.
Contact Cobolt technical support.
Interlock fault
1.
If using a custom interlock system, connect the Cobolt-supplied remote interlock connector plug to check
whether the interlock is correctly wired.
2.
This remote interlock connector should be connected as described in section 7.3.
3.
In the software, check that “Interlock Fault” is not displayed. Send the command “ilk?” to confirm the Remote
Remote interlock connector is not open (returns a 1 if closed).
4.
If it is verified that the Remote Interlock Connector system is closed yet an interlock fault is returned, contact
Cobolt technical support.
Laser emission stops
1.
Ensure the laser has adequate heat sinking.
2.
Check that the Remote Interlock Connector is connected.
3.
Send the command “f?”
4.
If fault code 1 is returned, check that the heat sink is adequate and that the ambient temperature is under
40°C.
5.
If fault code 3 is returned, see interlock fault checklist.
6.
If fault code 4 is returned, there may be a problem with the constant power system.
7.
Contact Cobolt technical support.
