      In what cases will the RUN output on a Power Supply Unit turn ON?

      The RUN output will turn ON when the CPU Unit is in MONITOR Mode or RUN Mode as long as a fatal error has not occurred.

      Normally, the RUN output turns ON approximately one second after the CPU Unit power is turned ON. The RUN output will turn OFF when the CPU Unit enters PROGRAM Mode or a fatal error occurs. The RUN output is enabled only for the Power Supply Unit on the CPU Rack.
