Minor Alarm
There are several conditions that can cause the front panel Fault lamp, or 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 322 for information on troubleshooting GNSS reception
issues.

Troubleshooting
Note: If SecureSync was just recently powered-up
or rebooted and input references are applied, no
troubleshooting may be necessary. Allow a few
minutes for the input reference to be declared valid
(allow 35 – 40 minutes for a new install with
GNSS input).
1) Make sure the Input Reference Priority table still
has the desired inputs enabled, based on desired
priority. Refer to "Configuring Input Reference
Priorities" on page 157 .
2) Make sure desired input references are still con
nected to the correct port of SecureSync.
3) Verify GNSS antenna installation (if applic
able). Make sure the antenna has a clear view of
the sky.
1) Verify GNSS antenna is connected to
SecureSync GNSS input connector
2) Check antenna cable for presence of an open
or a short. Refer to XXX for additional information.
