Why Schweitzer Engineering Laboratories SEL-3031 remote radio will not link up to the master?
- M
  Michael FlowersAug 3, 2025
  If the Schweitzer Engineering Laboratories Transceiver remote radio won't link to the master, there could be a few reasons. First, ensure that the radio address or mode is correctly configured. The master and remote radios must have the same address and SKIP settings. Also, confirm that the master radio's LINK light is on and that the NID address and SKIP setting are correctly configured on both units. Another potential issue is the antennas. Use QuickSet to issue the RAD command to check the signal strength. If the signal is weak, realign both antennas to improve signal strength and inspect the antenna cables for any damage.

  If you cannot change the radio settings on your Schweitzer Engineering Laboratories Transceiver, it might be due to an invalid password. To resolve this, install the password disable jumper and then change the passwords using the PAS command. Refer to the Password Jumper information on page 2.14 (in the manual) for guidance on disabling passwords.

  Bill WaltersAug 12, 2025
  If the ALARM LED on your Schweitzer Engineering Laboratories Transceiver flashes on every half second, it indicates the radio has detected a VSWR error, possibly due to an open or short on the antenna port. To fix this, check that all connections from the antenna to the radio are secure and inspect the antenna, feedlines, and lightning arrestor for any signs of damage.

Why is the SEC LED flashing on Schweitzer Engineering Laboratories SEL-3031 Transceiver?
- K
  Kyle JonesAug 17, 2025
  If the SEC LED is flashing on your Schweitzer Engineering Laboratories Transceiver, it means that the SEL-3031 detects the encryption card but the card is in reset and doesn't have the key set. To resolve this, use QuickSet and set the KEY setting. Ensure that this setting is the same on both radios.

  If the ALARM LED is ON on your Schweitzer Engineering Laboratories Transceiver, it means that the radio recognized a status failure. Turn the unit off, and then on, and issue the STATUS command. If the alarm signal returns, return the unit to the factory for repair.

  If the wall-mount Schweitzer Engineering Laboratories Transceiver radio will not turn on, the polarity of the power supply wires might be reversed. Check the polarity and reverse the wires if they are connected incorrectly.
