Inspect mounting enclosure
for unexpected heat sources
(i.e loose primary cables) and
remove accordingly
Ensure settings are not set
close to nominal ratings.
Ensure FlexLogic equations
do not have impractical
timing for status events
Ensure IRIG-B cable is
connected, check cable
functionality (i.e. physical
damage or perform
continuity test), ensure IRIG-
B receiver is functioning, and
check input signal level (it
may be less than
specification). If none of
these apply, contact the
factory.
Ensure that both the CPU
and Comms FW was
uploaded during the upgrade
process
Re-try uploading firmware. If
the upload doesn't work a
second time contact factory
Fix the remote CANBUS IO
mismatch.
