     The LON channel is DSLC/MSLC and EGCP-3 compatible. It may only be used with specified Woodward equipment. Fault Detection (Board Hardware) Each PowerSense board has a red fault LED that is turned on when the system is reset. During initialization of a board, which occurs after every CPU reset, the CPU turns the Fault LED on.

  • Page 102: Dle Serial Communication Board

    The Atlas system can be provided with a DLE serial communications board. The DLE board has six ports—three RS-422 ports for communication with Honeywell pressure transducer modules, and three RS-485 ports for use with Woodward LQ series and EM series drivers. All ports are special purpose and are not designed for general communication functions.

    The wiring must be one continuous cable between nodes, and must meet the requirements of EIA RS- 485 for 500 kbps except that Woodward recommends that the maximum cable lengths be cut in half because typical prime mover installations have high levels of electrical interference.
  • Page 104 Some users may not use both the RS-422 and RS-485 ports in their application. In this case, one LED will stay on all the time. This only signifies that one side of the board is not being used. It is not a failure unless a flash code appears. Woodward...
