February 12, 2025

The provided context does not contain specific steps for setting up the Nautel VX150 to auto-recover from an AC power outage. However, it does mention power supply modules, surge protection, and alarms, which may be relevant to power recovery. To ensure auto-recovery, verify that the AC power wiring is installed correctly, use the recommended power supply module, and check that the transmitter resumes normal operation upon power restoration. If further configuration is needed, refer to the transmitter's installation or troubleshooting manual.

    VX150 TO VX2 TROUBLESHOOTING MANUAL ELECTRICAL SCHEMATICS Unique Symbols Nautel uses unique symbols on electrical schematics to describe logic (two-state) signals. These signals differ from single-state signals or analog signals that may have multiple values. Type of Inputs and Outputs On electrical schematics, names used to describe logic (two-state) input and output signals are prefixed with a # symbol.
