4.3.2 Fault codes
NOTICE: if a fault occurs on the sensor during a gas alarm, the
fault overrides the alarm.
Sensor faults can be decoded using the following table. Note that
multiple faults can be reported at the same time. For example, fault code
00000003 is a combination of codes 00000001 (no sensor signal) and
00000002 (voltage out of specification 1 V).
NOTICE: if the “last fault” field indicates that a fault has occurred
at a certain time, but the corresponding “current fault” field does not
indicate a fault, the problem has been resolved on its own and no
service action is required.
