Indication Troubleshooting
All available Input References have
been lost. The Reference Status table
on the HOME page will show the cur-
rent status of all inputs (Green is valid
and Red is invalid or not present).
1. Make sure the Input Reference Pri-
ority table still has the desired ref-
erence inputs Enabled, based on the
desired priority. See
Input Reference Priorities" on
page 105
.
2. Make sure the desired input ref-
erences are still connected to the cor-
rect input port of VelaSync.
3. Verify GNSS antenna installation (if
applicable). See
GNSS Reception" on the next
page
.
Note: If VelaSync was just recently
powered-up or rebooted and input ref-
erences are applied, no troubleshoot-
ing may be necessary. Allow at least
10-20 minutes for the input references
to be declared valid and NTP to align
to the System Time (allow an addi-
tional 35-40 minutes for a new install
with GNSS input).
1. Verify in the Configure Reference Pri-
orities table that all available ref-
erences enabled. See
Input Reference Priorities" on
page 105
.
2. Verify that the Reference Status on
the HOME page shows "OK" (Green)
for all available references.
3. Verify NTP is enabled and con-
figured correctly. See
ence Configuration" on page 70
