Broken fan on argon laser
Locked
|
Dear List,
The fan on the argon laser of our Zeiss LSM510 has stopped working. The laser itself switches on but after a few minutes it will turn itself off, presumably due to overheating. I was wondering if anyone else has enocuntered this problem and if it can be rectified without replacing the entire laser unit. Many thanks in advance, Andrew |

Something similar happened to us recently. Have you tried a different power supply?

Just some more details: Our power supply (melles Griot) has a parallel-type connector with a plug (may not be using correct terminology). This plug must be well connected for the laser to operate properly. If it is loose then you may experience fan shut-down and other troubles.

Hello Andrew (& Listers),
The fan is a replaceable part, and yes the plasma
tube has a thermal switch on the cooling fins located at the anode
end. The tube usually breaks before the $0.50 thermal switch does... so I
would find a fan quickly. If you need help locating the correct replacement, we
can steer you in the right direction - please let me know which model laser you
have on your machine...
Best Regards,

Hi Andrew,
If the fan is a physically separate part that is linked to the laser unit by a power cable and an air handling tube, then my former lab dealt with the same problem a few years ago. Before replacing the fan (~$400 as an aftermarket part), make sure to check the relevant fuses in the laser power supply ($5 at Radio Shack). Replacing the fan unit will not fix a blown fuse. Melles Griot should provide you with diagrams to find the appropriate fuse for your particular model. One caution - It can be fiendishly awkward to get at the fuses in some M-G power supply boards. You might wan an experienced computer surgeon around to consult. Good luck and all the best, TF On Oct 28, 2009, at 7:11 AM, Andrew Lindsay wrote: > Dear List, > > The fan on the argon laser of our Zeiss LSM510 has stopped working. > The > laser itself switches on but after a few minutes it will turn itself > off, > presumably due to overheating.

Dear Andrew,
Yes your Laser is shutting down due to overheating! Don't run the laser too long with no fan as it will damage the laser tube. I would definitely check fuses in power supply or replace the laser Power supply if you have a spare, but I have had the umbilical cord go bad and cause the laser to run even when the fan is not working. The Fan motor could also be burnt out and need replacing. Do you have a fan on top of the laser or the remote cooling package? Regards Don Elsmore

Hi Andrew
We've had this happen in the past with the fan for the Argon laser on our Leica SP5. The fan stops or fails to switch on and there is an inbuilt safety mechanism which disables the Argon laser if the fan isnt on, so that it cant overheat. The actual problem in our case was a build-up of dust in the fan, so the fan just needed to be cleaned. Goodluck!

Cautious note: In my experience, many problems with the cooling system
of a laser, air-cooled or water-cooled, are actually problems with the flow sensors that manufacturers install to verify that there is enough coolant flow. A good precaution, but apparently these sensors are brittle components: I think we had two replacements on our Leica SP2, and the service people told us this is a relatively frequent problem.
