Commands and Tips for Thermo Scientific Devices
Finnigan/TSP: FL2000 and FL3000 Detectors: Troubleshooting

Why does the batch and the sample abort and the detector does not respond?

If the value for NumberOfScans and/or for the area to be scanned, specified by either ScanStartEmWavelength and ScanEndEmWavelength or ScanStartExWavelength and ScanEndExWavelength, is too large, it may happen that the sample is interrupted and the batch is stopped. (The reason is that the firmware does not respond.) Turn the instrument off and on again.

Why does the batch abort?

a) The batch aborts due to a communication timeout.

b) A TSP device is not ready for communication.

In both cases, the reason may be that TSP devices communicate via the Start and/or Stop input. Make sure that no cables are connected to these inputs or remove them if necessary.

Why doesn't the fluorescence detector respond?

Due to the extensive communication during connecting the device (following the Connect command), it may take up to 1 min until the device finally responds. The respective message is logged in the Audit Trail.
