Section 1 Troubleshooting the FiberOptix
The following sections provide detailed information on troubleshooting issues with the
Fiber Optic system. Subsequent pages list the status messages that may be viewed by
pressing HOME then SHOW STATS. These codes provide the current operational status
of the FOS electronics, connections and sensor. A description of the code, possible
alarms associated with that status code and the issues which may result in the code being
displayed are shown. Subsequent pages show possible symptoms, the possible related
status codes, possible causes and recommended troubleshooting actions.
NOTE: In all cases, if the Fiber optic system is or becomes non-operational, an alternate
AP source will be selected by Autopilot. If Operator mode is selected, an alternate AP
source should be selected by the user.
NOTE: The loss of the fiber optic signal does not impair functionality of the IABP system.
