"Lid" Error Message

Hey all,

I just got my machine running a few minutes ago after a minor circuit breaker repair. For some reason I keep getting the LID error after running the machine at 3200RPM for a couple minutes. The lid is well secured as far as I can tell. 

Any ideas what the reason might be for this message?

Inside the latch assemblies. Each latch unit has two switches (according to my paper manual; according to the manual on the site, one each). All switches have to be fully and securely closed for a run. You may have a mechanical or connection issue inside a latch unit, or maybe your lid isn't quite square/level after reassembling. If it was working before I'd check the lid first.

When you say the switche(es), are you referring to a component in the latch or on the circuit board? I see no loose connections on the circuit board. 

Thanks again

The lid may be mechanically latched but you might have an issue with the switch(es?) in the latch assembly, or possibly a loose connection to the circuit board (since you had it fully dismantled, it might be good to double-check). At the top of this page you'll see "View Thermo Scientific IEC Centra GP8 product details" under your post's title. Click on that link, then on the Documents tab where you'll find a service manual.
