In the Automatic Bypass switch, there has been a mismatch
detected between "open" request and "open" Feedback.
W5.164 Output current high
The output current loading on the system exceeds system
nominal rated current by more than a certain percentage.
W5.165 Output current too high
The system output current has been detected as exceeding
the maximum allowable.
