Faults are represented as a hexadecimal word comprising 16 bits:
Bit 0: 1 = Overload
Bit 1: Inverter
Bit 2: Bypass
Bit 3: Rectifier
Bit 4: Input
Bit 5: Phase sequence
Bit 6: Temperature
Bit 7: Battery test failure
Bit 8: Output
Bit 9: Load on bypass
Bit 10: Circulation (for parallel)
Bit 11: Slave receive failure (parallel only)
For example, fault 0009H = 0000000000001001 binary which translates as overload and
battery test failure.
