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 page267 for information on troubleshoot-
ing 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 ref-
erence.
When all input references were lost and Holdover Mode has since expired.
Timing System Error: A problem has occurred in the Timing System. Contact Oro-
lia technical support if the error continues.
5.1.2 Troubleshooting: System Configuration
One of the first tasks when troubleshooting a unit is to read out the current system con-
figuration (you may also be asked for this when contacting Orolia Technical Support.)
