Traffic Error
Primary
Abnormally high
amount of Broadcast
and Uni-cast traffic on
port 1 or port 4
Every 1 second Contact site IT department to
check network for
malfunctioning devices
Traffic Error
Secondary
Abnormally high
amount of Broadcast
and Uni-cast traffic on
port 5
Every 1 second Contact site IT department to
check network for
malfunctioning devices
Ambient
Temperature >80C
The ambient
temperature
surrounding the
product has exceeded
80C
Every 1 second Inspect mounting enclosure
for unexpected heat sources
(i.e loose primary cables) and
remove accordingly
Event Rate High Abnormally high
amounts of events have
been generated so the
relay has stopped
logging to prevent
further issues
Every 1 second Ensure settings are not set
close to nominal ratings.
Ensure FlexLogic equations
do not have impractical
timing for status events
IRIG-B Failure A bad IRIG-B input
signal has been
detected
Every 1 second 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.
Version Mismatch CPU and Comms do not
have the same revision
on firmware
Boot-up and Every 1
second
Ensure that both the CPU
and Comms FW was
uploaded during the upgrade
process
SelfTestFWUpdate The updating of the
firmware failed
Every 1 second Re-try uploading firmware. If
the upload doesn’t work a
second time contact factory
Remote CAN IO
Mismatch
The value of the cards
in the slots detected by
the Remote IO does not
match the value
validated by the user
configuration
Every 1 second. A
failure is declared after
60 consecutive failures
Fix the remote CANBUS IO
mismatch.
1. – Failure is logged after the detection of 5 consecutive failures
2. $ – is the slot ID (i.e., F, G, H etc.)
3.To disable Link Error Primary target when not in-use with SE order code, change IP
address to 127.0.0.1
