I am new to writing in the forum, but I have been reading for a long time now and I really learn a lot and really just love this resource.
I have a 5975C MSD running with Chemstation E.02.00 SP2. The GC is a 7890A with an FPD installed.
For the last few months the system periodically shuts itself off in the middle of a run. Initially the error was a 'BitMap Error' where the line in the TIC when absolutely crazy out of the chemstation window onto the desktop. There is actually a thread about this on this forum. I reinstalled Chemstation on a fresh PC, but with the SP2 and I transferred our methods and sequence files. This didn't the "BitMap Error" problem initially, however, leaving the window minimized and not having it run maximized seems to have stopped that error from occurring.
Now we are getting an error that says "MS Instrument Control and Calibration has encountered a problem and needs to close". Some times this is accompanied by, literally, 500 small windows that say "Data Retrieval Failure" and some time not.
Sometime we have no error at all, except that Chemstation has completely closed and and the only indication is in the MSLog which is kind of scares. Normally the error in the log says "No responce, cannot bring MS online (possible bad address or exsisting lock) (error 209)" Error 209 pertains to the Foreline pressure I think which was fine at that moment. In this situation I bealive that the MSD thought it was going into Vent State as if the Foreline pressure exceeded 300mTorr - which it hadn't and wasn't actually vented. After a vent cycle is the only time I can think of that Chemstation closes automatically.
I've remade all our methods from the default.m and run our sequences from the default sequence and haven't had an error in about 200 injections except this morning so I'm kind of eliminating a corrupt method or seq.
Last night we had the same error window, but nothing had been recorded in the log. It stopped recording yesterday morning the when sequence finished, but it had run around 30 injections since then with nothing recorded in the log, but the log restarted after I re-started chemstation.
Also, when chemstation is closed the GC goes into ready Status which is not good for us as it is coupled to a TD via remote start/stop cable. This doesn't happen on the other instruments. Is it possible to set the GC to go into waiting for host status when chemstation is closed.
I'm really really at a loss. Any insight would be SO helpful.
At this point I am leaning towards needing to replace the Smart Card - any thoughts on that.
I think we are going to try another fresh install of Chemstation with out the PS2 - could the FPD be creating problems in our method files?
This is a new issue, the instrument has run well as a VOA instrument for about 10 years.
Looking forward to hearing from you.
Thank you very much!
