Why does my Eltek BC2000 Controller show Unknown System?

During new installation / turn up of the plant, if the Eltek Controller displays Unknown System, make sure at least one rectifier module is inserted in the shelf.
Why does my Eltek BC2000 Controller show Unknown System?
During new installation / turn up of the plant, if the Eltek Controller displays Unknown System, make sure at least one rectifier module is inserted in the shelf.
Why is the Rectifier Alarms LED (Red) on my Eltek BC2000?
If the Rectifier Alarms LED (Red) is on, on the Eltek Controller, make sure rectifier shelves are not wired for 120V, 1 Phase AC input.
What to do if my Eltek BC2000 is not responding?
If the Eltek Controller is not responding, power cycle the controller by disconnecting it from the backplane of the shelf (it does not need to be removed, just powered off), and then reconnecting the controller to the shelf. Wait for 3 minutes or more to see if the message “Controller not responding” returns. If the message “Controller not responding” returns, or if the message “Starting App” persists (without returning to the main screen), contact Eltek Technical Support.
