Why does the relay on my Omega LVU500 close but not open again?
- S
  Sandra HigginsAug 17, 2025
  If the relay on your Omega Transmitter closes but doesn't reopen, an inductive kick might be holding it closed. If switching 24 VDC, ensure a diode is installed as a snubber. Note that the LVU500 series uses latching relays, so when power is removed, the relays will remain in their last state; for example, if the relay is energized, it will remain energized even when power is removed.

  If the LVCN414-SW software cannot detect the LVU500 series when connected to your computer with your Omega Transmitter, check the following: * Ensure the LVU500-USB Fob is connected to the USB port. * Verify all four wires (Red, Black, White, and Green) are securely attached to the Fob. * Check the Device Manager to confirm that both drivers (LVCN414-SW Configuration & EchoFob) are present. * If the above steps don't work, reinstall the LVCN414-SW software while the computer is in Safe Mode.

Why does my Omega LVU500 always jump to the LOST condition?

  If your Omega Transmitter always jumps to the LOST condition, check the dimensional configuration (Sensor Height and Fill Height) of the LVU500 series. Ensure that the Fill-H setting corresponds to the full level of liquid (measured from the bottom up) and not the distance from the transmitter to the liquid (top down).
