Why are irrigation functions disabled due to no power on my Rain Bird Control Systems?
- B
  Brian WilliamsSep 13, 2025
  This problem can arise from a couple of issues. First, there may be no primary power to the controller transformer. Check the power input to the controller transformer. The display is being powered by the 9v backup battery. Another reason may be that the front panel ribbon cable is disconnected. Check both ends of the ribbon cable to make sure it is firmly connected to the backplane and front panel.

How do I adjust the number of stations running at once on my Rain Bird Control Systems?
- J
  joe16Aug 23, 2025
  The number of stations operating simultaneously might be due to incorrect SimulStation configurations. To adjust this, turn the dial to Station Settings and select SimulStations. Select LXD SimulStations and adjust the maximum number of simultaneous irrigation stations you want to allow to operate across all programs at any time. Non- Irrigation SimulStations control stations with Non-Irr Priority. You can also select PGM SimulStations and adjust the maximum number of simultaneous irrigation stations you want to allow to operate simultaneously within the currently selected program. Move the Program slide switch to select the other programs (ABCD).

  This issue is often due to incomplete programming. Turn the dial to Test All Stations / Check System, select Confirm Programs, then Program Summary. Missing programming parameters are identified by an N. For programs to run automatically, you need to program Start Days, Start Times, and Station Run Times.
