• To check the status of the output circuits driving the output relay via the LHMI,
select Main menu/Monitoring/I/O status/Binary output modules and then
navigate to the board with the actual binary output to be checked.
• Test and change the relay state manually.
1. To set the IED to test mode, select Main menu/Test/IED test mode/
TestMode and set the parameter to "On".
2. To operate or force the output relay to operate, select Main menu/Test/
Forcing/Binary output values and then navigate to the board with the
actual binary output relay to be operated/forced.
3.
Select the BOn_PO to be operated or forced and press
operate the actual output relay.
Each BOn_PO is represented by two signals. The first signal in LHMI is the
