Add in detection of output overvoltage fault
If bit 5 of the lower byte to STATUS_WORD (STATUS_BYTE) is on when the
power is on, the power supply is indicating that it has detected an
output overvoltage fault condition. Log an error pointing to the power
supply that is indicating this overvoltage condition.
