FL-5000: How to utilize Real-Time Module Diagnostics

Topic

  • How to utilize Real-Time Module Diagnostics
  • FL-5000 mod self test. 

Environment

  • Product: FL-5000
  • Components: Module (version 212 or newer)
  • Control System: 

Steps

  • FL-5000 “smart” modules self-detect failures with diagnostic LEDs. The number of LEDs that display and whether they are solid on or blinking indicates the failure mode and location.
    • Both LEDs solid on = Critical error; replace the module.
    • Left LED blinking = Loss of communication, but port A is good. Either a cable is
      unplugged/bad or previous module port B is bad. If previous module port B is blinking,
      replace the cable. If previous module port B is solid on, replace the previous module
      and the cable.
    • Right LED blinking = No communication beyond this module, but port B is good. If next
      module port A is blinking, replace the cable. If next module port A is solid on, replace
      the next module and the cable
    • Left LED solid on = Loss of communication, port test failed; bad module or cable.
    • Right LED solid on = No communication beyond this module, port test failed;
      bad module or cable.
    • Blank modules between blinking LEDs = Power supply is unplugged/bad.
  • Notes:
    • If the display shows a Real-Time failure, cycle power to the displays to override the blanking and show content once again.
    • The example images below show displays with 4 modules each; total module numbers will vary depending on display sizes. 
    • Mods wired backwards will automatically show a left arrow (Only with mod version 261 or newer loaded).
