Hi all. My autosampler is installed on 5890 series 2 GC and when I begin my method, the autosampler starts to work and then all of a sudden shuts down. When I turn the power off and then on again, the 3 lights come on for just a second but then go off again. I can't get it back on. Any suggestions on what may be wrong? I've checked all the connections and they seem fine. I'm guessing there's an issue with a board or something but I have no idea where to go with it. Thanks in advance!!

Yes it seems to be a problem in the electronics or power supply of the controller. You could try to (please turn OFF the controller first!) disconnect the cable of the 7673 from the back of the controller, then connect the cable again (perhaps in the other position, I mean if it was in FRONT, then reconnect in REAR), turn it on again and let's see. If its only a bad connection it'll be solved, but it seems to be a issue with the electronics.

 If you have not repaired the autosampler:

1 if conncected to a controller are all the LEDs green (located lower left front when facing controller).  If not one LED may be  flashing, which is a error code that can direct you to problem with controller.

2. If controller checks  ok then look at the injection tower for the three LEDs on front, what code do they flash after attempting to inject sample?

All LEDs will flash similiar to morose code-  long and short flashes.  Once you determine the code you can find solution in manuals for controller (board replacement) or injector (motors).

A couple of other things to try is replacing the syringe; if the plunger is sticking that will force a shut down.  What solvent are you rinsing the syringe?  If it is very viscous then you will need to program the syringe to allow for drawing solvent more slowly.
