–
Check the input signal level (it may 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
: An Ethernet connection has failed.
•
How often the test is performed
: Monitored every five seconds.
•
What to do
: Check Ethernet connections. Port 1 is the primary port and port 2 is the secondary port.
•
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 SNTP configuration and network connections.
•
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.
•
What to do
: The “xxx” text denotes the data item that has been detected as oscillating. Evaluate all logic pertaining to
this item.
