6.2.2
Warnings
In case of a warning, the protection relay continues to operate except for those
protection functions affected by the fault. The main unit status LED remains lit as
during normal operation. If the device warning event is configured as alarms, the
LHMI Home button flashes red.
If a warning appears, record the name and code so that it can be
provided to ABB customer service.
On the LHMI, an active warning is indicated with a yellow LED. More information
about the warning and recovery options can be accessed by tapping More Information.
