Lock 'lost' on Bruker 400MHz NMR
 

Lock 'lost' on Bruker 400MHz NMR

I had just finished refilling the nitrogen and powering up the NMR after the holiday shutdown and went through the normal startup routine (cf, ii, cfbsms). When I ran lockdisp I could not get the lockdisplay window to appear, appearing to be stuck on 'checking rs-channel' and failing after 11 attempts.

Any help in the matter would be appreciated.

System details: XwinNMR 2.7 on SGI O2 with IRIX. Bruker Avance DPX400.

Things checked already:

• List item
• 2H cable connected
• No error lights on console, all power rails up, no loose cabling
• Restarted console and re-attempted to lockdisp -> failed
• Restarted computer and re-attempted to lockdisp -> failed
• Attempted autolock from bsmsdisp control panel -> failed, LOCK AH No FFASignal
