What to do if Rotem RLD 7.2 has no output in AUTO mode?
- C
  Charles VargasAug 5, 2025
  If your Rotem Controller is powered on but there's no output in AUTO mode using 0-10V control voltage or RX, TX communication lines: * For 0-10V control, ensure that the "+" and "COM" cables are correctly connected. Verify the voltage at the RLD terminal by setting 5V from the controller and measuring it. * For RX, TX communication, double-check that the RX and TX lines are properly connected and that you have interchanged RX and TX.
