•
How often the test is performed
: Every second
.
•
What to do
: Check direct input and output configuration and wiring.
•
Latched target message
: No.
•
Description of problem
: A bad IRIG-B input signal has been detected.
•
How often the test is performed
: Monitored whenever an IRIG-B signal is received.
•
What to do
: Ensure the following:
–
The IRIG-B cable is properly connected.
–
Proper cable functionality (that is, check for physical damage or perform a continuity test).
–
The IRIG-B receiver is functioning.
–
Check the input signal level (it can be less than specification).
If none of these apply, then contact the factory.
•
Latched target message
: No.
•
Description of problem
: No PTP enabled port has good PTP signal input.
•
How often the test is performed
: Activated when no acceptable signal is being received.
•
What to do
: Ensure the following:
–
The Ethernet cable(s) are properly connected.
–
At least one PTP grandmaster-capable clock is functioning.
–
If strict PP is enabled, that entire network is PP compliant.
–
The network is delivering PTP messages to the relay.
•
Latched target message
: No.
•
Description of problem
: The SNTP server is not responding.
•
How often the test is performed
: Every 10 to 60 seconds.
•
What to do
: Check that Ethernet cable(s) are properly connected. Check that configuration for the SNTP server
corresponds to the actual server settings. Check connectivity to the server (ping the server IP address.
•
Latched target message
: No.
•
Description of problem
: A discrepancy has been detected between the actual and desired state of a latching contact
output of an installed type “4L” module.
•
How often the test is performed
: Upon initiation of a contact output state change.
•
What to do
: Verify the state of the output contact and contact the factory if the problem persists.
•
Latched target message
: No.
•
Description of problem
: A data item in a configurable GOOSE data set is oscillating.
•
How often the test is performed
: Upon scanning of each configurable GOOSE data set.
