I am working with an Agilent 1200 equippped with degasser, quaternary pump, autosampler and DAD. Originally it was eqipped with an ELSD as well but, few days ago we disconnected it.
I disinstalled Chemstation, I disconnected the ELSD, and we re-installed the software.
Now, the problem is that the modules are recognised, they have green icons and they look ready but Chemstation is 'not ready' (red) and not turn into the ready mode (green).
When I launch the run this is what happen:
1) The status of the system change from 'Not Ready' (in red) to 'Run in progress/data aquisition' (in blu)
2) Where it was written 'last run' and '00' it appears 'nRdy Wait' and '10.0'
3) A countdown from 10.0 to 0.0 starts.
4) When the countdown arrive at 0.0 a new window appears: 'instrument nRdy timeout occured'
5) After that the situation comes back to the starting point (Not ready in red)
It looks like the HPLC is waiting for something to be ready but I can not find any info about what it is waiting for. Even in the loogbook I can not have any info a part
'method started'
'instrument running sample vial 1'
'instrument nRdy timeout occured'
and, eventually, 'method aborted'.
I would like to underlight that:
1) I checked the firmwares and they are updated
2) I checked all the cables and they are not loosing
3) The HPLC does not ask for the missing ELSD so, I suppose, it is not the problem...
4) The ELSD was connected via an RS 232 cable to the PC.
I do not know what to do or check...
Do you have any suggestions?
Thanks a lot in advance!
Cheers
