Automatic Thermal Shutdown Monitoring

Once NI-RFSG has completely loaded, the RF enclosure is powered on. After that time, circuitry on the NI 5610 upconverter module continuously monitors device temperature. The RF enclosure is powered off before the temperature raises high enough to damage the NI 5610.

If safe temperature limits are exceeded, the NI RF signal generator hardware is shut down and the NI-RFSG software returns an error. You must perform a device reset to restore power to the RF enclosure. Reset the NI RF signal generator hardware by right-clicking both hardware modules in MAX and selecting Reset Device or by calling the niRFSG Reset Device VI or the niRFSG_ResetDevice function.

Note  The NI 5610 is warm to the touch during normal operation. It should never reach a temperature high enough to cause thermal shutdown unless the fan or vents on the PXI or PXI Express chassis are blocked or the filters on the fans are excessively dusty. If you get a thermal shutdown error, make sure that the filters are clean and that you have a clear path for airflow through your PXI or PXI Express chassis. Review the guidelines in the Maintain Forced-Air Cooling Note to Users document that shipped with the product and make any necessary adjustments to ensure that the device is cooled effectively.
