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
and
or
to
operate the actual output relay.
Each BOn_PO is represented by two signals. The first signal in LHMI is the
actual value “1” or “0” of the output, and in PCM600 a lit or dimmed diode.
