Hello Vitor,
this message usually comes up if the require sensor is not detected (either because it is faulty, or because it is not inserted) by the system - e.g. if you want to start a temperature controlled method with Rotor 16, the software will require a pT-Sensor to be installed for the temperature control. If that sensor is not inserted into the rotor, or is not detected by the instrument, the reported error message will pop up.
Can you provide me with more information about the used method, rotor/sensors used, screenshots ...?
Please send this information along with your contact information to: support-asc[at]

Best regards,
René
