5.1 Troubleshooting
The Web UI provide VersaSync status information that can be used to help
troubleshoot failure symptoms that may occur.
5.1.1 Minor and Major Alarms
Minor Alarm
There are several conditions that can cause the Web UI status lights to indicate a
Minor alarm has been asserted. These conditions include:
Too few GPS satellites, 1st threshold: The GNSS receiver has been tracking
less than the minimum number of satellites for too long of a duration. Refer
to "Troubleshooting GNSS Reception" on page309 for information on
troubleshooting GNSS reception issues.
Major Alarm
There are several conditions that can cause the Web UI status lights to indicate a
Major alarm has been asserted. These conditions include:
Frequency error: Indicates a jump in the oscillator’s output frequency has
been detected. Contact Tech Support for additional information.
1PPS is not in specification: The 1PPS input reference is either not present
or is not qualified.
Not In Sync: A Major alarm is asserted when the Timing System is not in
sync (Input references are not available and the unit is not in Holdover).
Examples of not being synced include:
When the Timing System has just booted-up and has not yet synced
to a reference.
When all input references were lost and Holdover Mode has since
expired.
Timing System Error: A problem has occurred in the Timing System.
Contact Safran technical support if the error continues.
Timing System Hardware Error: An issue has been detected with the unit
hardware. One possible cause is that the oscillator is not functioning prop-
erly.
