What to do if Nautel Transmitter shows 'Controller: SWR Shutback'?
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 NV30 and how to fix it?
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 Transmitter shows 'Controller: SWR Shutdown'?
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?
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?
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 NV30 Transmitter displays 'Module #: PS 1 (or 2) High Temp'?
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 NV30 shows 'Exciter A/B: Exgine Offline'?
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 NV30?
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 NV30?
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 NV30 Transmitter?
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.
