Commands and Tips for Thermo Scientific Devices
Thermo Scientific Accela/Surveyor Plus PDA and TSP UV6000 PDA Detectors: Troubleshooting

How can I turn on the lamps?

The PDA detector does not automatically turn on the lamps at power-up. To turn on the lamps, connect the PDA detector to Chromeleon, and issue the corresponding commands.

Why can't I reconnect the PDA detector?

It is not always possible to reconnect the PDA detector after a breakdown in communication. In this case, turn the detector off and on before reconnecting.

Why can't I start data acquisition?

Is an AS3500 or an AS3000 autosampler installed for which Inj Hold Active has been set to HI? Set this option to LO; otherwise, data acquisition cannot start.

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 are connected with the System Interconnect Cable or communicate via the Start and/or Stop input. Make sure that no cables are connected to these inputs or remove them if necessary.
