Door Detection Sensors Reporting Failed

Symptoms

  • Why does my controller show a few door switches reporting as failed?

Environment

  • Vanguard Display
  • Vanguard Control board (VCB)
  • Multiple door switch's

Cause

  • Too many door switches added in peripherals. the sign has two door switches but each switch is wired in series so any "open" triggers the single door detection sensor. The Traffic Cabinet has two door switches, and each switch is wired in series so any "open" triggers the single door detection sensor.

Resolution

  • Delete unnecessary door switches.
  • Refer to  config sheet for correct setup of peripherals.
  • Open and close doors in the display and TC  one at a time and verify they report properly in the View Peripherals menu in the controller.
