Checking the communication link operation

There are several different communication links on the product. First check that all
communication ports that are used for communication are turned on.
1. Check the front communication port RJ-45.
1.1. Check that the uplink LED is lit with a steady green light.
The uplink LED is located on the LHMI above the RJ-45 communication
port on the left. The port is used for direct electrical communication to a PC
connected via a crossed-over Ethernet cable.
1.2. Check the communication status of the front port via the LHMI in Main
menu/Test/Function status/Communication/DOSFRNT:1/Outputs.
Check that the LINKUP value is 1, that is, the communication is working.
When the value is 0, there is no communication link.
2. Check the communication status of the rear port X1 via the LHMI in Main
menu/Tests/Function status/Communication/DOSLAN1:1/Outputs.
The X1 communication port on the rear side of the IED is for optical Ethernet via
LC connector.
• Check that the LINKUP value is 1, that is, the communication is working.
When the value is 0, there is no communication link.

Checking the time synchronization

• Select Main menu/Diagnostics/IED status/General and check the status of the
time synchronization on Time Synch.
The Time synch value is Ready when the synchronization is in order.
Note that the time synchronization source has to be activated.
Otherwise the value is always Ready.

Running the display test

To run the display test, either use the push buttons or start the test via the menu.
• Select Main menu/Tests/LED test.
•
Press or simultaneously
All the LEDs are tested by turning them on simultaneously. The display shows a
set of patterns so that all the pixels are activated. After the test, the display returns
to normal state.
