Appendix A3
A3.4 Inverter warnings and alarms
The inverters used to drive the dry pump and booster can also generate warnings and alarms if problems are
encountered. Inverter warning and alarm codes are displayed by the PDT if fitted.
The alarm and warning codes are each reported as a 16-bit word encoded as 4 hexadecimal numbers. The codes are
displayed as follows:
1234 5678
Where:
The first 4 digits signify an alarm code and,
The second 4 digits signify a warning code
Digits 1 – 8 are reported as hexadecimal digits from 0 to F.
To determine the cause of a warning or alarm you must first decode each hexadecimal number. 0 indicates that there
is no alert for that bit. Normally you will only see codes of 1, 2, 4 or 8 for each bit but if two or more events occur
in the same bit then these will be added together.
For example:
5 = 1 + 4 so if code 5 is displayed it means that alerts 1 AND 4 are active
B = 1 + 2 + 8 so if code B is displayed it means that alerts 1, 2 AND 8 are active.
To decode inverter warning and alarm codes, refer to Table A31 to convert the hexadecimal digits into alert
combinations and then refer to Table A32 and A33).
