3 Checking the self supervision signals
3.1 Reconfiguring the IED
I/O modules configured as logical I/O modules (BIM, BOM or IOM) are supervised.
I/O modules that are not configured are not supervised.
Each logical I/O module has an error flag that indicates signal or module failure. The error flag
is also set when the physical I/O module of the correct type is not detected in the connected slot.
3.2 Setting the IED time
This procedure describes how to set the IED time from the local HMI.
1. Display the set time dialog.
Navigate to:
Settings\Time\System time
Press the E button to enter the dialog.
2. Set the date and time.
Use the Left and Right arrow buttons to move between the time and date
values (year, month, day, hours, minutes and seconds). Use the Up and
Down arrow buttons to change the value.
3. Confirm the setting.
Press the E button to set the calendar and clock to the new values.
3.3 Checking the self supervision function
