    What to do if Nautel Transmitter shows 'Controller: SWR Shutback'?
    • K
      Kristopher ShahAug 18, 2025
      If the Nautel Transmitter controller displays an 'SWR Shutback' error, which is often due to a transient SWR condition like an arc or lightning in the output transmission line or antenna system, try pressing the Reset button to clear the latched condition. Also, inspect the output transmission line for any punctures or damage.

    What causes 'Module #: PS 1 (or 2) AC Fail' in Nautel NV5 and how to fix it?
    • B
      brandonmooreAug 20, 2025
      The 'Module #: PS 1 (or 2) AC Fail' error in your Nautel Transmitter indicates that one of the two module power supplies is reporting an AC failure because its AC input voltage is less than 175 V AC. To resolve this, check the AC voltage applied to the power supply module that is reporting the error.

    What to do if Nautel NV5 Transmitter shows 'Controller: SWR Shutdown'?
    • F
      fullerpatrickAug 23, 2025
      The 'Controller: SWR Shutdown' message on your Nautel Transmitter means there have been repeated SWR Foldback alarms, equivalent to a 3:1 SWR. See 'Controller: SWR Foldback' for troubleshooting tips.

    What does 'Module #: PS 1 (or 2) Fail' mean on a Nautel Transmitter?
    • C
      Cindy HollandAug 26, 2025
      The message 'Module #: PS 1 (or 2) Fail' on a Nautel Transmitter indicates that the output voltage of the power supply module is outside its acceptable range, based on the control setting. If the DC voltage is out of tolerance, replace the power supply module.

    How to troubleshoot 'Exciter A/B: Dead Air' on Nautel Transmitter?
    • S
      Sandra PowellAug 28, 2025
      The 'Exciter A/B: Dead Air' error on a Nautel Transmitter means the exciter’s audio modulation level is below the level specified in the dead air settings of the active preset. To fix this, check the appropriate program inputs and the dead air setting for the preset.

    What to do if my Nautel Transmitter displays 'Module #: PS 1 (or 2) High Temp'?
    • J
      Jason KellerAug 30, 2025
      If your Nautel Transmitter displays 'Module #: PS 1 (or 2) High Temp', it means the power supply module's operating temperature has exceeded its internal threshold. Temporarily pull out the power supply module.

    Why Nautel Transmitter shows 'Exciter A/B: Exgine Offline'?
    • I
      Ian RogersSep 2, 2025
      The 'Exciter A/B: Exgine Offline' error on a Nautel Transmitter means the exciter isn't communicating with the Exgine PWB (A3). Check the ribbon cable between the Exgine PWB (A3) and J15 of the NVE exciter PWB (A1), and also check the Exgine PWB itself.

    How to fix 'Exciter A/B: PA Over Temperature' on Nautel Transmitter?
    • M
      Matthew EdwardsSep 4, 2025
      The 'Exciter A/B: PA Over Temperature' error on a Nautel Transmitter indicates that the temperature sensed within the exciter’s RF power stage exceeds 70°C (158°F). Check the exciter fan’s air path to resolve this.

    What causes 'Controller: VDC A (or B) Fan Fail' in Nautel NV5 Transmitter?
    • R
      rperrySep 7, 2025
      The 'Controller: VDC A (or B) Fan Fail' error in your Nautel Transmitter occurs if the fan A or B voltage, measured on the power supply distribution PWB (A7), is below the low fan voltage threshold (40 V). Verify the voltage on TP1 (A) or TP2 (B) of the power supply distribution PWB. If the voltage is low, check the connections between the fan power supply module, its PS interface PWB and the power supply distribution PWB.

    What does 'Exciter A/B: Invalid HD Data' mean on Nautel NV5 Transmitter?
    • F
      farmerstaceySep 9, 2025
      The 'Exciter A/B: Invalid HD Data' error on a Nautel Transmitter means IBOC data is detected from the Exgine PWB, but it's not usable (all logic 0s). Check the IBOC data source.
