FTS 370x Alarms Review

Vanguard Medium 370d tower light

POWER FAIL

Description:

  • Input power failure
  • PCB 1 is operating on battery backup
  • Possible cause: Input power loss

Next steps:

  • Check internal and external breaker

CFG ALARM

Description:

  • SC is detecting devices that it is currently not configured to support

Next steps:

  • Check CONFIG settings

TWR SYNC

Description:

  • SC is detecting devices that it is currently not configured to support

Next steps:

  • Check CONFIG settings

BIND ALARM

Description:

  • 1 or more SCs are not bound correctly
  • A ‘SYS COMM’ alarm will accompany the ‘BIND ALARM’
  • 1 or more SCs are bound to the same connected equipment

Next steps:

  • Unbind and rebind tower while following the correct “power down” procedure
  • See FTS 370x binding process for more information

DAY ALARM

Description:

  • FH is exhibiting a white day alarm
  • Possible causes:
    • Light output decreased by 25%
    • Skips 4 or more consecutive flashes

Next steps:

  • Check A2D values

WNIGHT ALARM

Description:

  • FH is exhibiting a white night alarm
  • Possible causes:
    • Light output decreased by 25%
    • Skips 4 or more consecutive flashes

Next steps:

  • Check A2D values

RNIGHT ALARM

Description:

  • FH is exhibiting a red night alarm
  • Possible causes:
    • Light output decreased by 25%
    • Skips 4 or more consecutive flashes

Next steps:

  • Check A2D values

BCN COMM

Description:

  • FH not communicating with SC
  • Possible causes:
    • Not detecting PLC from SC (wiring or power related)
    • Failed core PCB

Next steps:

PD ALARM

Description:

  • More than 19 hours have passed since the system has changed modes via the photodiode (system 1 only)

Next steps:

  • Check photodiode connections
  • Verify that outside light sources are not influencing PHD operation
  • Suggested parts: photodiode, PCB1

 

Possible options to control the mode until the site visit, if current/active NOTAM is present:

  • Change the tower type to red.
  • Verify if the photodiode has failed in night mode by checking photodiode mode on the home page. If yes, then set Disarm Photodiode Alarm to On in the tower lighting configuration web page.
  • Start long duration mode override to red night for dual tower types.

 

Recommend the customer’s compliance department be notified before changes are made.

IR ALARM

Description:

  • FH is exhibiting an IR alarm
  • Possible causes:
  • Light output decreased by 25%
  • Skips 4 or more consecutive flashes

Next steps:

  • Check A2D values

GPS ALARM

Description:

  • GPS sync has not occurred for a period of 1 hour or more
  • Possible causes:
    • GPS antenna failure or damage
    • GPS chip on PCB3 Smart Board

Next steps:

  • Verify unobstructed view of the sky

IR N/A

Description:

  • Infrared is not available or supported by the attached FH

Next steps:

  • Verify correct FH and/or core PCB is installed

MKR COMM

Description:

  • The SC is experiencing a comm failure with the connected marker interface board and is not detecting PLC from SC (wiring or power related)

Next steps:

  • Replace marker board

MKR ALARM

Description:

  • The connected marker interface board is reporting failure of 1 or more markers
  • The exact marker(s) that have faulted are included in the INFORM

Next steps:

  • Replace MKR
  • Recommend having spare MKR PCB

POWER FAIL

Description:

  • Any communication failure in the system will generate a SYS COMM failure on System 1.
  • The SYS COMM alarm will be accompanied by a specific communication alarm if the failure is local to System 1.
  • Absence of a specific communication failure on System 1 indicates a communication failure on a subordinate unit (System 2-6).
  • A communication failure on any subordinate unit will be accompanied by a SYS COMM alarm.

Next steps:

  • Varies based on alarms accompanied with SYS COMM
  • Rebooting every 4-5 minutes = PCB1 failure
  • “Reboot Code A” in event log every 10 minutes = Failure of data cable link (RS485) between controllers
  • Verify configuration is appropriate (specifically # of BCNs)

LI TEST MODE

Description:

  • System 1 is conducting a lighting inspection test

Next steps:

  • User initiated LI

LOW DC

Description:

  • Output voltage (~60 VDC) to the connected FH and marker tier (if present) is low

Next steps:
