Agilent 7200 QTOF MS Faults Mainboard Shutdown

Hi all,

Out of the blue our QTOF returned the following series of faults, the instrument was sitting idle for 4/5 days when this occurred:

The fault can be cleared, but will return within a few seconds/minutes, leaving the instrument in an error state.

The instrument has been vented and left overnight. Upon powering back on, the series of faults has immediately returned.

Any help is much appreciated, thanks!

  • The Main board #1 shutdown cascades, so the other three shutdowns more than likely happen due to the MB1 shutdown. That could be something as simple as a not-fully-seated cable to a real problem with the board or any of the three piggybacked to it.  It also shuts down to protect the instrument and so could be related to any of the parts that it controls -- which is a lot!
