Common problems

4
  • Shutdown indicator LED is illuminated.
    Fix: Resolve shutdown condition.
  • Lug Door Open indicator LED is illuminated.
    Cause: Lug-box door is open.
    Fix: Close lug-box door. If condition remains unresolved, inspect lug-box door safety switch for proper operation.
  • Low Load indicator LED is illuminated.
    Cause: Genset has operated at less than 30% capacity for more than 15 minutes.
    Fix: Increase electrical load. If unable to operate genset at more than 30% load, use a smaller generator.
  • Emergency Stop indicator LED is illuminated.
    Cause: Emergency Stop switch is active (pushed in).
    Fix: Deactivate (pull out) Emergency Stop switch.
