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

LHMI Home button flashes red.
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
